    摘要: The present invention discloses a base station system, including an indoor part and a remote RF subsystem (RRS). The indoor part includes a RIU, a CCU, a BBU, a GPSU and a local interface unit. The RRS includes a remote interface unit, a RF transceiver unit (TRU) and an antenna. The local interface unit and the remote interface unit are for signal intercommunicating between the indoor part of the base station and the RSS. The TRU is a RF transceiver module of the conventional RFU, for amplifying an analog RF signal from the remote interface unit and transmitting the signal to the antenna. By flexibly selecting between an optical cable and an If cable, the interface unit of the present invention provides a digital baseband remote manner and an IF remote manner. According to the structure of the base station of the present invention, the number of the base station sites and the network operating cost decreases; on the other side, since one base station may cover a cell by smart antenna with only one optical cable or IF cable, the difficulty in mounting is reduced.

    摘要: The present invention discloses a functional electrical stimulation system comprising a primary power, a boost module, an energy storage section, an output control relay, an automatic discharge circuit, a foot/hand controlled switch, a current detection chip and a current limiting fuse. The boost module comprises n DC chopper circuits connected in series, and outputs a high voltage of 100-200V. According to an enable signal and a current detection signal, the output control relay disables/enables the DC boost module. The automatic discharge circuit discharges capacitance of the energy storage section automatically when the relay turns off the power input. The Foot/hand controlled switch, the current detection chip and the current limiting fuse form a triple accident protection circuit. The functional electrical stimulation system maximizes the intensity of electrical stimulation within the range that the human body can withstand. Meanwhile, it provides multiple security protection mechanisms and enhanced reliability to avoid danger during the use.

    摘要: An input device includes an optical waveguide, one or more light sources, one or more imaging sensors, and a translator. The optical waveguide has an input surface, a back surface substantially opposite the input surface, and a side surface therebetween. The input surface has a plurality of different input locations. The one or more light sources are positioned to introduce light into the optical waveguide. A distortion of each different input location of the input surface causes a portion of light within the optical waveguide to exit from the optical waveguide at a different escape location of the side surface. The one or more imaging sensors are positioned and aimed to detect an escape location of a portion of light exiting from the side surface. The translator determines an input location corresponding to the escape location for each detected escape location.
