Title: Apparatus and method in a communication network
Inventor: POON KAR-FAT
IPC: H04W36/12
Filed: 1997-12-16
Abstract: The present invention relates to a method and a mobile station for use in a communications network of GSM type, or a type derived from GSM. According to the invention the identification of an unidentified BCCH carrier is initiated in the mobile station when said BCCH carrier on the basis of measured signal strengths is foreseen soon to be one of the strongest BCCH carriers with regard to the signal strength average value over a measuring period. The delay from the point in time when the BCCH carriers becomes one of the strongest BCCH carriers, taking into account the signal strength average values over a measuring period, to the point when the BCCH carrier has been identified can in many cases be reduced or in some cases eliminated. Thus the mobile station can report measurement data for the BCCH carrier to the network at an earlier stage so that handover to the corresponding cell may be made faster.

Patent CA-2289440-A1 (CA)
Title: Transmitting system for small-sized vehicle
Inventor: YOSHIMOTO TOKUJI
IPC: F16H47/06
Filed: 1999-11-12
Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, the fluid transmitting device and a shifting clutch being mounted on the crankshaft and connected in series to each other. One of the fluid transmitting device and the shifting clutch is connected to the crankshaft, and the other is connected to the input shaft of the multi-stage transmission through a primary reducing device. Thus, when the multi-stage transmission is to be shifted, the shifting operation of the multi-stage transmission can be carried out lightly, irrespective of a creep phenomenon of the fluid transmitting device, by bringing the shifting clutch into its OFF state. Moreover, the burden of torque by the fluid transmitting device and the shifting clutch mounted on the crankshaft which is rotated at a higher speed than that of the input shaft of the transmission is relatively small. Therefore, the capacities of the fluid transmitting device and the shifting clutch can be reduced correspondingly, leading to a reduction in size of the fluid transmitting device and the shifting clutch.
