Abstract

The purpose of this device is to allow a delivery vehicle to arrive at a distribution center/manufactur- ing site and by means of information and data delivered in route by wide area r.f transmission to the device, to locate and access the correct entry point by transmitting from the device an identitica- tion access coded signal to a receiver located in the site. The device would allow access to the site by transmitting the proper radio signal I.D. (access code) to a radio controlled gate at the site entrance. Fur- ther the vehicle would be assisted as to which door to deliver to by the reading alphanumeric directions transmitted to the device. At the proper delivery door the vehicle operator would again be able to operate the radio controlled access door by trans- mitting the proper I.D. (another additional access code) from the device.

The device would allow access to the site by transmitting the proper radio signal I.D. (access code) to a radio controlled gate at the site entrance.

At the proper delivery door the vehicle operator would again be able to operate the radio controlled access door by trans- mitting the proper I.D. (another additional access code) from the device.

  Referring to the Diagram, in the preferred appli- cation the following elements are used to imple- ment the idea. An alphanumeric pager/communicator comprised of 1) a high sensitivity RI? receiver/de- modulator used for large geographic area radio recep-

tion, 2) a microcomputer controller with memory storage (RAM), 3) a LCD (or equiv.) visual display, and 4) a low power RF wideband transmitter using spread spectrum Code Division Multiple Access (CDMA) for short range transmission/activation of access poi...
