DETAILED DESCRIPTION - FIG. 1 illustrates an embodiment of an occupancy sensing system in accordance with some inventive principles of this patent disclosure. The embodiment of FIG. 1 contains a pc workstation 10 and an occupancy sensor 12 organized to watch a space 14 associated with the pc workstation for one or more occupants. The occupancy sensor 12 generates an occupancy signal in response to monitoring the space. A connection sixteen between the occupancy sensor and the pc workstation enables the computer workstation 10 to course of the occupancy signal and carry out one or more energy management capabilities in response to the occupancy signal. A pc workstation (or "computer" or "workstation") refers to a mix of enter, output, and computing hardware that can be used for work or leisure by an individual, and includes desktop computer systems, notebook computer systems, terminals linked to networks, and so on. The computing hardware might embrace a central processing unit (CPU) to execute program instructions. The workstation could process the occupancy sign from the occupancy sensor with software program that uses CPU cycles to carry out its features. Processing the occupancy sign may be performed as a low precedence process on the CPU. Implementing the occupancy signal processing as a low precedence process might combine properly with other CPU processes because, if the workstation is in use and other greater priority course of are operating, there isn't a concern that the low priority occupancy signal processing is slowed down. However, if the occupancy sensor is checking for occupancy, then the workstation is unlikely to be in use, and free CPU cycles are available. Furthermore, processing the occupancy sign with workstation CPU cycles can also enable the processing energy of the occupancy sensor to be lowered, thereby reducing its value. The occupancy sensor 12 has a subject of view 18 that permits it to watch the house 14 associated with the pc workstation. The occupancy sensor 12 could also be based mostly on any suitable sensing technology corresponding to passive infrared (PIR), ultrasonic (U/S), audio, video, and so forth., or any combination thereof. FIG. 2 illustrates one other embodiment of an occupancy sensing system in response to some inventive principles of this patent disclosure. FIG. 3 illustrates another embodiment of an occupancy sensing system in line with some inventive principles of this patent disclosure. The embodiment of FIG. 3 is much like the embodiment of FIG. 1 but within the embodiment of FIG. 3, the workstation 24 includes functionality 26 that permits a consumer to regulate a parameter of the occupancy sensor at the workstation. The adjustable parameter may embody a time-out delay, sensitivity setting, and so on., for the occupancy sensor. The connection 32 may be integral with the connection 16 that carries the occupancy sign, or it may be a separate connection. FIG. Four illustrates one other embodiment of an occupancy sensing system in accordance with some inventive rules of this patent disclosure. The embodiment of FIG. 4 is similar to the embodiment of FIG. 2 however the embodiment of FIG. 4 consists of load monitoring apparatus 34 that enables the workstation 36 to observe one or more masses by a connection 38 to the workstation. The load monitoring apparatus 34 could also be separate from, or integral with, power switch 20, and permits the workstation to find out power, voltage and/or current ranges, as well as on/off standing and different parameters of an electrical load. FIG. 5 illustrates an embodiment of a computer workstation based on some inventive principles of this patent disclosure. The workstation forty two of FIG. 5 includes a show 44 and a CPU 46. An occupancy sensor forty eight is mounted to the show to facilitate monitoring the space related to the workstation. The occupancy sensor forty eight may be separate from, or integral with, the display 44, and could also be based mostly on any appropriate sensing know-how. The occupancy sensor forty eight generates an occupancy sign which is transmitted to the CPU 46 by a connection 50, which could also be carried out with any suitable wired or wireless connection. FIG. 6 illustrates an exemplary embodiment of a pc workstation based on some inventive ideas of this patent disclosure. The workstation fifty four is proven divided into hardware and software components. As defined above, the operating system fifty six typically contains internal power management options 88 that can be configured to turn off numerous items of hardware to scale back energy consumption when the workstation is just not getting used. The inner power management options 88 built into the operating system work on the assumption that the workstation is now not in use when no consumer inputs within the type of key presses or mouse movements have been acquired for a predetermined period of time. Basing power management selections on the amount of time with out person inputs to the workstation, nonetheless, usually results in incorrect assumptions that end in devices being turned off and/or the workstation being locked down whereas the person continues to be present at the workstation. Moreover, if the user does leave the workstation shortly after the last person enter action, the workstation could also be left unattended, absolutely powered, and unsecured throughout your complete time-out durations set for the assorted elements. The applying software fifty eight could embrace internal energy administration functionality 78 that makes choices in response to the actual presence or absence of a consumer at the workstation slightly than assumptions based mostly on the period of time with out consumer input actions. The internal power management performance 78 determines the state of an occupancy sign from an occupancy sensor 28 by means of a USB port 68 and makes use of this information to make decisions on when to show off energy to varied items of hardware, place the workstation in a suspend, sleep or hibernate mode, and/or lock down the workstation and require the user to re-enter a password. Utilizing an occupancy sensor to manage the interior power management functions of a workstation may reduce energy consumption and/or enhance workstation security. For example, occupancy sensors that use ultrasonic sensing expertise tend to have good sensitivity to the "small motions" which can be typical of a person working at a desktop, and subsequently, might present an accurate indication of the presence of an occupant at a workstation. Due to this fact, the timeout delay for the occupancy sensor 28 could also be set to a relatively short period of time, e.g., a couple of minutes, with out producing false indications of an unoccupied situation on the workstation. This will likely result in decreased power consumption and improved safety as a result of the show, exhausting drive and different hardware may be turned off and the workstation locked down shortly after the consumer leaves the workstation. Moreover, the usage of an occupancy sensor to control the inner power administration capabilities of a workstation could reduce or remove situations during which hardware is turned off and/or the workstation locked down despite the fact that the user continues to be current on the workstation. The application software 58 may additionally include software program to interface the workstation to a lighting management system or different building automation system via the community interface card 76 or by way of every other appropriate interface. The consumer interface software program 80 may also allow a consumer to configure which inside and exterior power management actions to absorb response to the occupancy sensor 28 comparable to turning off the display 62 or arduous drive 64, placing the workstation in a low power mode such as sleep, suspend, hibernate, etc., locking down the workstation with password protection, turning off switched receptacles in a number of power strips 89 and 90, turning off external equipment with in-built energy management capability equivalent to printer 92, or speaking with a lighting management system or different building automation system by means of the network interface card. The person interface might also allow the consumer to configure the appliance software to show off internal or external hardware instantly upon receiving an unoccupied indication from the occupancy sensor, or after a number of further time delays. Varied extra time delays could also be used to stagger the occasions at which completely different pieces of hardware are turned off, in addition to when they're turned back on to forestall excessive energy surges when the presence of a person at the workstation is detected again. The user interface can also enable a consumer to course of and/or view the power consumption of the workstation and/or any peripherals having energy monitoring capability in actual time, as well has historic information of energy consumption to search for patterns that may provide indications of how to realize additional vitality savings. The user interface might also enable the consumer to configure the system to report power consumption knowledge to a lighting control system or different building automation system for additional processing and analysis. The applying software may be carried out with an software programming interface (API), thereby enabling it to hook, and be hooked by, other software. A few of the appliance software functionality could also be implemented with a user interface that is just like a standard screensaver, and one or more portions of the applying software may be selected from a screen saver portion of the working system. Nonetheless, the configuration and different hooks could also be particular to the occupancy sensing and energy switching units and their own resident packages. The inventive principles should not limited to instance implementation particulars proven in FIG. 6. For instance, the connections made through the USB ports and NIC could also be carried out with wireless connections similar to Bluetooth, or may use different wired connections corresponding to DisplayPort or HDMI connections. Energy line communication (PLC) connections may be used to communicate with power switches in energy strips or in switched receptacles located in wiring units near the workstation. Furthermore, switched energy receptacles could also be built-in instantly into the workstation to control energy to peripheral gadgets in response to an occupancy sensor that's connected to the workstation. FIG. 7 illustrates an embodiment of a dialog box for implementing a person interface in line with some inventive rules of this patent disclosure. The dialog field ninety four includes graphical "slider bars" for setting the sensitivity, area of coverage (by way of viewing angle) and time-out delay for an occupancy sensor that is capable of receiving adjustable parameters. The dialog box additionally contains check packing containers to specify which internally managed hardware akin to displays (monitors) and arduous drives, as well as which externally managed hardware resembling energy strips, must be turned off in response to the occupancy sensor. FIG. 8 is a block diagram of an embodiment of an occupancy sensor in keeping with some inventive ideas of this patent disclosure. The occupancy sensor 96 contains a number of sensors 98 based on any suitable sensing expertise or technologies. A controller one hundred processes uncooked signals from the a number of sensors 98 and generates an occupancy signal which is transmitted by way of a USB port 102. Conventional sensitivity and time-out delay controls 104 could also be included to allow the controller to regulate the occupancy sensor for the specific house it is configured to watch. Alternatively, or additionally, the controller could modify the occupancy sensor in response to adjustable parameters that it receives by the USB port 102. One or more indicators 106 could also be included to display the occupied/unoccupied standing as determined by the occupancy sensor. For example, a tri-color LED could also be configured to display crimson for an unoccupied situation, inexperienced for an occupied situation, and yellow for a fault condition. A "wake now" enter permits a user to take the system out of unoccupied mode if the sensor doesn't detect when the consumer returns to the workstation. Electronics in the occupancy sensor or application software program within the workstation could improve the sensitivity setting of the occupancy sensor each time the wake now button is pressed, since this may point out that the sensitivity setting is simply too low. FIG. 9 is a block diagram of an embodiment of a energy strip in line with some inventive principles of this patent disclosure. The power strip 110 of FIG. 9 receives input energy from a connection 112 which may embrace a plug-and-cord assembly, connector prongs to plug instantly right into a receptacle, and so on. A predominant change and/or circuit breaker and/or surge arrestor 114 receives the input power which is distributed on to a primary set of receptacles 116 that are energized when the ability switch 114 is closed. The workstation interface 130 allows the facility strip to speak with a workstation via a wired or wireless connection utilizing any appropriate interfacing association. The power monitor circuit 128 could include any appropriate circuitry to watch the voltage, present, energy, and so forth., of any load related to any of the switched or unswitched receptacles. In some embodiments, a commercially available meter chip could also be used along with a present sense transformer and voltage sense leads to supply a low-cost solution that could be simply integrated into the power strip. The person interface 126 might include any type of inputs and/or outputs to allow a consumer to configure and/or management the power strip, enter parameters, examine the status or performance history of the ability strip, and so on., from the ability strip itself. The person interface could include one or more input devices reminiscent of a potentiometer or different analog input, digital switches of any sort together with DIP switches, toggle switches, rotary switches, and many others. The consumer interface may embrace one or more output gadgets corresponding to lights, LEDs, numeric displays, alphanumeric displays, dot-matrix displays, and many others. The user interface may be configured to enable a person to set a number of time delays that management the operation of the switching circuit as described beneath, in addition to communication protocols, and/or additional time delay, and/or another parameters. The communications with the workstation could also be just one-manner to regulate a number of sets of switched receptacles, or bi-directional to enable reporting of power monitoring information to the workstation. In some embodiments, the controller 124 in the power strip could also be configured to turn each sets of switched receptacles 120 and 122 on or off at the identical time as soon as it receives a command from the workstation. In other embodiments, the controller could delay turning considered one of the 2 units on or off to avoid energy fluctuations, surges, and so on. Alternatively, the totally different sets of switched receptacles one hundred twenty and 122 may be managed by totally different commands from the workstation which can include logic for staggering load turn-on and switch off, or for controlling the two sets of receptacles in a different way in response to totally different occupancy situations on the workstation. For example, different hundreds could also be turned on or off in response to totally different occupancy sensors in a multi-sensor association as described below. FIG. 10 is a perspective view of an instance embodiment of an occupancy sensor based on some inventive rules of this patent disclosure. The embodiment of FIG. 10 may be used, for example, to implement embodiment of FIG. 8. The occupancy sensor of FIG. 10 includes a compact housing 132 to facilitate straightforward mounting on a workstation display. The front of the housing includes two ultrasonic transducers 134 and 138 that are mounted on a convex surface to provide a defined coverage sample (discipline of "view") for ultrasonic occupancy sensing. A mini USB port 140 permits using a standard USB cable to connect the occupancy sensor to a USB port on the workstation. A removable panel 142 conceals commonplace management dials for sensitivity and time-out delay settings. A pushbutton 144 may be used to implement the "wake now" function described above. In some embodiments, the coverage sample of the occupancy sensor may be adjusted by disabling one of the transducers, or by providing different weighting to the outputs from the transducers to implement a beam forming approach. The occupancy sensor of FIG. 10 could also be mounted in any appropriate location using any suitable approach corresponding to clips, magnets, two-sided tape, hook-and-loop fasteners similar to Velcro, and so forth. In some embodiments, a dedicated communication cable for connecting to a workstation could also be permanently connected to the housing utilizing a strain relief. Alternatively, or in addition to a USB port or everlasting cable, a wireless interface using radio frequency (RF) or infrared (IR) expertise could also be included for communication with the workstation. An Infrared Information Association (IrDA) suitable interface 148 is shown in FIG. 10 to implement IR communications. RF communication could also be achieved with an antenna that's inner to the housing if the housing is made from plastic. FIG. 11 is a perspective view of an instance embodiment of a power strip in response to some inventive ideas of this patent disclosure. The embodiment of FIG. 11 could also be used, for example, to implement the embodiment of FIG. 9. The ability strip of FIG. Eleven features a housing 150, a plug-and-cord assembly 152, a predominant energy change 154, an IrDA receiver 158, and a sort-B USB port 156 for connecting the facility strip to a computer or different tools. Two sets of receptacles 160 and 162 are de-energized when the primary energy swap 154 is within the OFF place. FIGS. 12 and thirteen illustrate a facet elevation view and a high plan view, respectively, of an example of the protection sample 164 that could be achieved with the occupancy sensor of FIG. 10. The occupancy sensor 131 is mounted to the top of a workstation show 166 that is situated on a desk 168. In this instance, the workstation CPU is included within the display 166 and is managed by keyboard 170. As seen in FIGS. 12 and 13, the protection sample 164 contains the user's chair 172 and other areas associated with the workstation that the consumer is more likely to occupy whereas actively working on the workstation. These areas embrace a printer 174, a activity lamp 176 and an area heater 178. The coverage sample is typical of the pattern which may be achieved with a two-transducer ultrasound system. This sample could also be altered by turning off or weighting the outputs from one or more of the transducers as described above, or by utilizing different occupancy sensing applied sciences. FIG. 14 is a high plan view of a workspace associated with one other embodiment of a workstation occupancy sensing system according to some inventive ideas of this patent disclosure. The workspace of FIG. 14 is an workplace having a door 180, a desk 182, a chair 184 for the office's major occupant, visitor chairs 186, and a whiteboard 187. A workstation display 188 has two occupancy sensors 190 and 192 which are mounted on prime of the display and related to the workstation through USB cables or different varieties of connections as described above. The first occupancy sensor 190 has a coverage sample 194 that is usually supposed to include solely the house that's prone to be occupied by the principle occupant of the workplace while working alone. Each of the occupancy sensors 190 and 192 may be connected to the workstation and configured and operated as described within the context of systems having a single occupancy sensor as described above, however with separate settings and actions defined for each occupancy sensor. For instance, room lighting or space heating in the office maybe turned on in response to both of the two occupancy sensors detecting an occupied situation, whereas the show, and any task lighting, printer, or other peripherals located on the desk 182 could only be managed in response to the occupancy sensor 190 having the protection pattern 194 that features the desk space. FIG. 15 illustrates another embodiment of an occupancy sensing system based on some inventive principles of this patent disclosure. The embodiment of FIG. 15 contains a number of workstations 200, every workstation having an occupancy sensor 202 connected to the workstation using any of the methods described above. Every workstation additionally has no less than one constructing mild fixture 204 that illuminates the area related to the corresponding workstation. The stream of power to the constructing lights is managed by a load management gadget 206 in response to commands received from a building automation server, workstation, or different controller 208. The load management machine 206 and constructing automation or lighting system controller 208 and workstations 200 are related to a constructing community 210 by way of community adapters 212, 214 and 216, respectively, as well as their own particular person community interface playing cards. The constructing network 210 may be implemented with Ethernet, CAN or other kind of network suitable for building automation, vitality management, and so on. The load management system may be applied with a relay cabinet, dimmer rack, distributed relay/dimmer system, and many others., or some other network related load management machine. The building automation controller 208 provides the general operational logic for the system. When the controller 208 receives a message from one of the workstations indicating that the associated occupancy sensor has detected an unoccupied situation for the associated area, it points a command to the relay cabinet instructing it to turn off the light for the space related to that workstation. Upon receiving a sign from a workstation that the related space is as soon as once more occupied, the controller signals the relay cabinet to restore energy to the light for that area. A potential advantage of the system illustrated in FIG. 15 is that it could enable lighting and different building automation techniques to higher accommodate occupants in cubicles or other relatively small spaces. Conventional lighting control programs and other building automation methods sometimes make use of ceiling or wall mounted occupancy sensors. Cubical spacing requires more densely placed sensors with correct alignment difficult by the situation of overhead lighting fixtures, heating ventilation and air conditioning (HVAC) tools, sprinklers, etc. Furthermore, the frequent rearrangement that is common with cubical spaces presents an extra problem to correct alignment of occupancy sensors. The inventive ideas referring to workstation-based occupancy sensor systems described in this patent disclosure, however, might scale back or eradicate these problems as a result of the occupancy sensor for every workstation and its associated workspace could also be positioned very simply in a close location that reliably monitors the area most prone to be occupied by the workstation consumer. Moreover, the inventive principles may cut back the price and uncertainty associated with mounting quite a few occupancy sensors on ceilings or walls of buildings. In embodiments through which a workstation is networked to a lighting management system or other constructing automation system, the applying software program might implement a blink warning override characteristic. For example, the lighting control system may be configured to turn off the lights in a constructing space in response to a timer-based vitality conservation schedule. In such a configuration, the lighting management system sometimes turns the lights off briefly (a "blink warning") prior to actually turning off the lights to notify occupants of the impending automated turn-off. After the blink warning, the lights are held on lengthy enough to allow occupants to go away the world or enter a request to the lighting management system to keep the lights on. Inputting a request usually requires the occupant to find a control station for the lighting control system. The nearest control station may be a substantial distance from the occupant's workstation. In response to some inventive principles of this patent disclosure, the applying software could robotically notify the lighting control system that the house related to the workstation is occupied, and therefore, automatically override the blink warning for the light or lights that illuminate the area related to the workstation. Alternatively, or in addition, the appliance software program could receive a message from the lighting management system when a blink warning is imminent, and current a pop-up message or dialog box to the occupant advising the occupant of the impending blink warning. This may merely notify the occupant of the blink warning occasion, or the occupant may then be allowed to elect by means of the workstation to override the blink warning, or to permit the blink warning to proceed as normal. In embodiments during which a workstation is networked to a lighting management system or different constructing automation system, the applying software can also present different override options. For instance, if the lighting control system is configured to show off the lights in a building space in response to a timer-primarily based energy conservation schedule, the appliance software program could request that the lighting control system maintain the lighting within the area associated with the workstation, regardless of any blink warn performance. The maintained lighting could include not solely the house related to the workstation, but also any related areas to permit for egress from the area. The appliance software may even be configured to permit or override an attempt by a networked building automation system to sweep off energy receptacles within the space associated with the workstation if the occupancy sensor indicates that the space is occupied. The sweep-off functionality may be integrated with, or separate from the blink warning override functionality. In embodiments by which a workstation is networked to a lighting control system or other building automation system, the application software program may additionally present load monitoring data to the management or automation system if there is any load monitoring apparatus connected to the workstation. This will enable the lighting management system or different constructing automation system to judge the effectiveness of the occupancy sensing and load management functionality of the workstation-based mostly occupancy sensing methods, in addition to their interplay with other constructing automation methods. In places where a handheld or different distant control is used for native control of lights in a lighting control system or different building automation system, a workstation having an occupancy sensor linked may be additional related to the distant control as a method to interface the workstation to the management or automation system. For example, an current handheld distant management may provide on/off and dimming control of overhead lights by an IR receiver in a digital wall swap or photocell device. A further wired or wireless connection may be created between the handheld distant and the workstation to enable the workstation to manage the lighting in response to the occupancy sensor via the handheld remote, thereby eliminating the necessity for a network connection between the workstation and the lighting management system or constructing automation system. Alternatively, a wireless connection may be created immediately between the workstation and the receiver that is utilized by the handheld distant, thereby allowing the workstation to speak straight with the lighting control system through the present system elements and without the need for a further network connection. The strategies and apparatus described above enable the implementation of countless options based on the inventive principles of this patent disclosure. Some instance implementation details are described under to illustrate the numerous features and benefits which may be realized. The inventive principles, however, aren't limited to these example particulars. Though any suitable occupancy sensing know-how, or combination thereof, may be utilized, ultrasonic sensing may be particularly effectively suited to the small spaces and small motion that will should be detected for occupants performing workplace work in a cubicle. Mounting the one or more occupancy sensors on a workstation display may provide very best converge because workstation users usually arrange their complete workspace around the show. Utilizing an occupancy sensor that generates a conventional occupancy sign that gives a binary occupied/unoccupied indication may simplify implementation and allow the use of existing occupancy sensing circuitry which has been subjected to in depth troubleshooting, high quality tuning and value reduction. Nevertheless, other types of occupancy sensors that provide extra uncooked output such because the unprocessed output from an ultrasound transducer or infrared pyrometer could also be used, and the computing energy of the workstation may be used to course of the uncooked output to make the occupied/unoccupied determination. The occupancy sensors could embody onboard electronics which are only adequate to adjust the sensitivity and time-out delay based mostly on local inputs on the occupancy sensor, or the electronics may be in a position to adjust the occupancy sensor in response to adjustable parameters which are enter by a workstation person by a pop-up or management panel and transmitted through a USB or other wired or wireless connection. Energy strips having a number of switched and unswitched energy receptacles may present an ideal platform to switch power to exterior workstation peripherals corresponding to task lighting, printers, area heaters, and many others., in response to an occupancy sensor coupled to the workstation. Nevertheless, other power switching platforms could also be used together with single-receptacle plug-in modules that plug instantly into a wall outlet without a power cord and communicate with the workstation by way of a wired or wireless connection equivalent to a Bluetooth wireless interface. Other examples include building wiring units comparable to wall shops that have switched receptacles and communicate with the workstation by means of a wired or wireless connection. One type of power strip might embrace a USB connection to the workstation with a mixture of switched and unswitched receptacles as shown in FIGS. 9 and 11. One other kind of receptacle might not have a connection to the workstation, however as a substitute may be linked directly to the occupancy sensor by way of a wired or wireless connection. Such an embodiment might have built in sensitivity and time-out delay performance and should include consumer inputs to adjust these parameters. In embodiments through which a workstation could also be positioned in a standby or hibernate mode when the area associated with the workstation is unoccupied, the power for the USB or other connection to the occupancy sensor may be turned off. Therefore, the workstation operating system could need to be configured to wake when it receives a signal on the USB or different connection. The inventive principles of this patent disclosure have been described above with reference to some specific example embodiments, but these embodiments may be modified in association and detail with out departing from the inventive ideas. For instance, a few of the embodiments described above are illustrated in the context of lighting control techniques, but the inventive rules may be applied to HVAC methods, security systems, etc. As an additional example, much of the functionality within the embodiments described above is described in the context of a software program implementation, however any of the functionality may also be carried out with analog and/or digital hardware, software, firmware, or any suitable combination thereof. Such adjustments and modifications are thought-about to fall throughout the scope of the following claims.
