摘要： 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. On embodiment relates to improvement in a passenger conveyance vehicle having front, back and side portions defining an enclosure for occupation by one or more passengers, one of the side portions having therein at least one door mechanism enabling passenger ingress to and egress from the vehicle, the side portion being hereinafter referred to as the door side, the improvement comprising a frontal transmitter disposed at the front of the vehicle and delivering a frontal frequency modulated lightwave signal in a three-dimensional pattern so as to enable a person disposed ahead of and on the door side of the approaching vehicle to be within the frontal signal pattern as the vehicle continues along at least a substantial portion of its normal line of travel and approaches such person; the front signal, if suitably received and converted, providing intelligible communication to a person within the frontal signal pattern. In another embodiment, the invention provides a passenger transit system comprising a) a plurality of terminals at which one or more conveyance vehicles periodically arrive and depart, the terminals each having at least one adjacent walkway, and the conveyance vehicles each having front, back and side portions defining an enclosure for occupation by one or more passengers, one of the side portions having therein at least one door mechanism enabling passenger ingress to and egress from the vehicle; and b) at least one transmitter disposed at each of one or more of the terminals, each transmitter delivering a frequency modulated lightwave signal in a three-dimensional pattern so as to enable a person using the walkway to be within the pattern of the transmitter as the person approaches the respective terminal; the signals from each of the transmitters being the same or different, and if suitably received and converted, providing intelligible communication to a person within the pattern. In a preferred embodiment, the transit system further comprises a frontal transmitter as described above.

摘要： A communications network comprised of a source of information to be transmitted in the form of a signal, one or more transmitters which emit light suitable for illumination and including means for modulating the light with the information signal, a medium such as a fluid through which the light passes, and one or more receivers for receiving the light and demodulating the signal to obtain the information. A user for the information may be a device, such as a computer or a compact disk player, or it may be a person, perhaps with some form of sensory or mental impairment. The information may be encrypted, may provide directional guidance, such as to a user moving in a vehicle, and/or may be transmitted simultaneously over multiple channels. Various types of visible light assemblies may be employed, with varying power inputs and outputs.
