  • Publication number: 20040137898
    Abstract: A system for communicating label specific information which comprises a communication network (20) in communication with a computer database (18), at least one transceiver (10), and a plurality of labels (12). Each label (12) is disposed on an object in the environment with which a unique identification code is associated and is configured and is configured to transmit a lightwave signal (A) indicative of the code. The transceiver (10) is configured to receive the lightwave signal (A), process the lightwave signal (A) to obtain the code, communicate through the communication network (20) with the computer database (18) to download information associated with the unique identification code obtained and communicate the information to a user.

  • Publication number: 20020149491
    Abstract: An egress system for use in a structure which defines a plurality of paths of travel where the system comprises one or more visual signs, each visual sign being located at a selected point along one or more paths of travel and each visual sign being configured to convey information in the form of visual communication and to convey at least two alternative messages. The system further comprises a central processing unit and one or more sensors being configured to detect an environmental condition and to send a signal indicative of this condition to the central processing unit. The central processing unit is configured to determine the safest of the paths of travel based upon signals received from the sensors and to send a processed signal to each of the visual signs to thereby cause the visual signs to convey a pre-selected one of at least two alternative messages, thereby visually identifying at least one of the safest paths of travel under the condition(s) detected.

  • Patent number: 6186396
    Abstract: Systems which comprise an automated transaction machine which includes one or more customer interacting means such as, in the case of an integrated circuit card terminal, at least an integrated circuit card reader; infrared communication emitters and individual short range infrared communication emitters located in the machine. The emitters are adapted to provide repeating, directionally sensitive frequency modulated message signals identifying the direction to and location of the machine. Thus, a person having a portable receiver for such signals is led to the machine and is able to position himself/herself in front of the machine in order to operate it. The respective emitters provide separate repeating, directionally sensitive frequency modulated message signal which identifies the location of the respective customer interface on the machine so that by movement of the portable receiver in front of the machine, the location on the machine of the respective customer interfaces can be determined.

  • Patent number: 6002138
    Abstract: A unitary hollow device adapted for covering a source of lightwave energy, apparatus comprising the combination of such device and such energy source, and a system comprised of a combination of the apparatus and a portable directional receiver. The energy source can be as simple as one or more light bulbs. However preferably the combination involves use of an array of light emitting diodes for transmitting infrared signals from fixed installations to be picked up by print-disabled persons with hand-held receivers which convert the signals to intelligible communication to enable the persons to be guided to desired locations. The device protects the energy source from accumulation of dust and other debris yet is configured to provide little, if any, interference with the transmission of the emitted signals. The device also conceals the energy source to thereby diminish theft and vandalism.

  • Patent number: 5757530
    Abstract: Described are apparatus for transmitting light wave signals, the apparatus being capable of adjusting their signal strength to automatically adapt to changes in the ambient light conditions of their surrounding environment. In one embodiment, the apparatus for transmitting lightwave signals comprises (a) an emitter for sending a frequency modulated lightwave signal of variable intensity, (b) a light energy receiver for detecting a change in the level of surrounding ambient light energy and for producing a response to such change in proportion to the change detected, and (c) a controller for adjusting, directly or indirectly, the frequency modulated lightwave signal in response to the light energy receiver response to the change detected. Audio transmission systems employing apparatus of this invention are also described.
