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.

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.

Abstract: Described are novel passenger conveyance vehicles and passenger transit systems which are configured to transmit signals which, when properly received and converted, provide intelligible non-visual communication to current and/or prospective passengers.

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.
