Abstract: In a wireless communication system including at least a first (101) and a second base transceiver station (201), a method for providing time adjustment to the second base transceiver station (201) is presented. The method includes supplying an identity of the first and second base transceiver station to a mobile station (103), and based on the identity, tracking a first signal from the first base transceiver station (101) and a second signal from the second base transceiver station (201) by the mobile station (103). The method further includes determining a timing adjustment calculation based on a first time offset of the first and a second time offset of the second signal by the mobile station. And finally, the method includes transmitting the timing adjustment calculation to the second base station transceiver (201), the timing adjustment subsequently used to adjust the timing of the second base station transceiver (201).

IPC: G01N27/404

Abstract: The invention relates to a gas sensor and its method of manufacture. Electrochemical gas sensors usually comprise an external housing, which acts as a reservoir for electrolyte; a wick to keep electrodes wetted with the electrolyte and external electrical terminals, for making electrical contact with the electrodes. Typically a gas permeable/microporous membrane has been used to seal a gas sensor in order to prevent leakage of electrolyte. A problem with existing sensors has been that there was a risk of electrolyte leaking through the membrane around the region where electrical connector passed therethrough. The present invention overcomes this by providing a method of urging conductive polymer through the membrane under controlled conditions of heat and pressure, thereby ensuring the integrity of the membrane remains intact whilst defining an electrically/conductive pathway therethrough.
