  • Radio frequency message apparatus for aiding ambulatory travel of visually impaired persons
    Patent number: 5144294
    Abstract: A radio frequency message apparatus for aiding ambulatory travel by handicapped persons such as blind individuals. The apparatus generally comprises a portable, radio frequency transceiver and a stationary, radio frequency base transceiver unit. The portable radio frequency transceiver is carried on the person of the handicapped individual and transmits a message request signal in response to manual activation of a transmit button thereon by the handicapped individual. The message request signal is received by the base transceiver, which causes the base transceiver to transmit a pre-recorded message signal back to the portable transceiver unit in radio frequency form. The message signal contains location identifying information such as the streets of an intersection at which the base unit is located.
