Abstract:

A vehicle or other host station includes first and second antennas, a fast semiconductor switch, a switching controller, and an RF receiver. The controller toggles the switch at a calibrated switching rate to selectively and alternately connect the first antenna to one of the RF receiver and a load having a calibrated impedance value. The first antenna may be a parasitic element in any embodiment using the load. The semiconductor switch may be a CMOS device or a Gallium Arsenide semiconductor switch. A switching control method for use in a vehicle or other host station having the first antenna, the second antenna, and the RF receiver includes transmitting a switching signal from the controller to the switch, and toggling the switch at a calibrated switching rate in response to the switching signal to selectively and alternately connect the first antenna to one of the RF receiver and the load.

Abstract:

A transit system including a system data processor in communication with a driver data processor of a driver electronic device and a rider data processor of a rider electronic device. The system data processor receives vehicle information of a vehicle from the driver. data processor. The vehicle information includes a vehicle route and a geolocation of the vehicle. The system data processor receives a geolocation of a rider electronic device from the rider data processor, and sends the vehicle information and advertisement information over a communication network to the rider data processor. The advertisement information is based on the vehicle information and the geolocation of the rider electronic device.
