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.

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.
