Abstract: This invention provides a method for telecommunication carriers to generate revenues from location-based services (LBS) through a location-based game (LBG). Also provided is a method for administrating a location-based game and mobile terminals configured with LBG of the present invention. Games of the present invention may be played in stationary mode, mobile mode, or any combinations thereof; they may also include a scoring system that is based on token collection and, therefore, does not require real-time update or fast response from the LBS.

Abstract: A multi-port receiver with a sophisticated signal processing technique for demodulating radiofrequency (RF) modulated digital signals that simplifies the multi-port receiver hardware. A section of a transmission line with coupling probes is used as a six-port circuit. Fixed probes distributed along the transmission line sample the resulting wave pattern at different phase shifts and the outputs of the probes are connected to power detectors. Statistical digital processing of the detector outputs recovers the transmitted signal. Power dividers and hybrid couplers are not required.

Abstract: The present invention is a method and an apparatus to use carrierless signals for energizing remote passive or active transponders (tags) and for communication link between a reader and the transponders. The reader's transceiver generates very short high power pulses to transmit them to the transponder which receives and stores the pulse energy in an energy store on the transponder. At the transponder the power pulse signal is compressed by a matched filter and rectified. Information to be transmitted from the reader to the transponder and from the transponder to the reader can be added to the data pulses by means of pulse position modulation, bi-phase modulation or other well-known wide-band modulation techniques. The communication is active as the transponder utilizes stored power for transmission and reception of signals while the transponder can be passive and is powered by the reader's signal energy.

Abstract: Tests of a semiconductor IC is conducted first by bringing a plurality of conductive pattern circuits formed on an insulator sheet into contact with a plurality of bump electrodes formed on a substrate of the semiconductor, second by connecting a plurality of signal transmission pattern circuits formed on a transmission circuit substrate with each conductive pattern circuit of the insulator sheet, and then by connecting the transmission circuit substrate with a body of the testing device. A probing test can be simplified since there is no need to manually adjust positions of conventional probe needles. Further, semiconductor ICs having a lot of bump electrodes can be test without being damaged.
