Definitions

  • radiofrequency transmissions raise security concerns because transmissions using RF can be easily intercepted, in part because of the fact that RF signals are designed to radiate signals in all directions.
  • radio frequency transmissions may be regulated by the Federal Communications Commission (FCC) which may control the frequencies that may be used for RF transmission.
  • FCC Federal Communications Commission
  • RF by its very nature is susceptible to interference and produces noise.
  • a building may accommodate very different numbers of occupants at different times within a relatively enclosed space, such as a meeting or class room.
  • the number of occupants is known to significantly alter the temperature and associated need for HVAC control.
  • other factors such as weather conditions and sunlight or lack thereof through windows in a room may have as much or greater effect on the need for HVAC control.
  • many older buildings were only provided with a single central thermostat, providing the same amount of heating or air conditioning to a room or other space regardless of demand for the same.
  • Newer HVAC systems enable control, through electrically controlled dampers or vents within the HVAC system to much more precisely respond to the needs of a single space or room within a building.
  • the room may not be individually controlled.
  • FIG. 2 is a front view of an alternative embodiment of the Communication System.
  • the present preferred apparatus may be used for detection and location.
  • an unauthorized person When a building is dark, in many cases an unauthorized person will rely upon a flashlight to move through the building. Most preferably, optical detector 3103 will detect this unidentified light source. In such case, since the location of optical detector 3103 is known precisely, the location of the unauthorized person is also known. Further, even as the unauthorized person moves about, so the unauthorized person will be tracked by virtue of the light emitting from the unauthorized person's flashlight.
  • LED optical transmitters 3102 , 3104 may be used to guide the emergency personnel to the exact location of the unauthorized person.
  • the emergency personnel may not be limited to police. As may by now be apparent, ambulance workers as well as police would appreciate flashing directional lights because quicker access to an emergency scene could potentially save lives.
  • This custom guidance system can include red, white or other suitably colored or illuminated lights which may be steady or flashing for emergency situations.
  • Slave clock 3107 communication can further be shared with optically-enabled name tags, telephones, TV and music, Internet, public address, computing devices of all sorts, ranging from hand-held devices such as Personal Digital Assistants (PDAs) to massive mainframe computers, and including Personal Computers (PCs), printers, network storage devices, other security and safety devices, appliances, EVAC systems, manufacturing machinery, and so forth.
  • PDAs Personal Digital Assistants
  • PCs Personal Computers
  • printers printers
  • network storage devices other security and safety devices
  • appliances EVAC systems, manufacturing machinery, and so forth.
  • any device which incorporates or can be made to incorporate sufficient electronic circuitry may communicate with slave clock 3107 to exchange information at any time.
  • the intelligent audio/visual observation and identification database system may also be coupled to various infrared or ultraviolet sensors, in addition to the optical sensors incorporated directly into LED optical transmitters 3102 , 3104 and optical detectors 3103 , and used for security/surveillance within a structure to assist in the early identification of an unauthorized individual within a security zone or the presence of an intruder without knowledge of the intruder.
