    摘要: A code-division multiple-access receiver carries out the following steps whenever it recognizes a symbol boundary in the received baseband signal. First, using the despreading code of the relevant station, it estimates the value of the symbol. Next, using the spreading code of the station, it estimates an interference signal, and modifies the baseband signal by subtracting the interference signal. These steps can be iterated for each symbol. The iterations can be organized into stages, with estimated symbol values from one stage passed to the next stage for use in estimating new symbol values in that next stage. At the end, the remaining baseband signal can be used to adjust the final estimated symbol values.

    摘要: An engagement fixture of a shoulder belt is connected to and supported by an engagement buckle disposed in a vehicle interior. When a platform is positioned in a getting in/out position in a vehicle exterior, the engagement fixture of the shoulder belt can be temporarily connected to a temporary fastening fixture provided to the platform. To the contrary, when the platform is positioned in a loading position in a vehicle interior, a connection condition of the engagement fixture of the shoulder belt can be changed from a temporary connection of the fastening fixture to a securely supportable connection of an engagement buckle in the vehicle interior. Thus, it is possible to simplify a belt attaching operation after a wheelchair is loaded in a vehicle while a columnar support member used in the conventional platform is abolished.

    摘要: A mechanism for rotating a vehicle seat body and a mechanism for restraining rotation of the seat body are partially shared, reducing the number of parts. The seat includes a seat body, a seat rotation mechanism, a gear forming member having a rotation gear, a drive gear meshable with the rotation gear, and an actuator for rotating the drive gear. The seat further includes a moving mechanism that relatively moves the drive gear and the gear forming member in a direction of a rotation restraint position such that the drive gear is placed in such a position so as to interfere with the gear forming member when the seat body rotates to a first position and when the seat body is urged to rotate in a direction of a second position while the drive gear is in such a position so as to not mesh with the rotation gear.

    摘要: A method of switching a communication channel when a mobile station moves from one service area to another service area is disclosed. The mobile station determines a difference between the transmission phase of a frame synchronizing signal received from a first base station currently holding a communication channel with the mobile station and the transmission phase of a frame synchronizing signal received from a second base station expected to newly set up a communication channel with the mobile station. The mobile station sends phase difference information representative of the above difference to the first base station via the communication channel. The first base station having received the phase difference information transfers the information to the second base station, causing it to correct the phase of data thereof to be sent to the mobile station. This successfully implements soft handover while guaranteeing the phase synchronization of frames sent from the two base stations.

    摘要: In flowing a switching current through an inductive load by way of an H-bridge circuit, a control circuit and a timing signal generating circuit are used to start a current supply operation in accordance with a driving period of a predetermined frequency, thereby increasing the current flowing through the inductive load. In reducing the current, a power source regeneration operation is performed during a power source regeneration period and a commutation operation is performed during a commutation period. The power source regeneration operation and the commutation operation are well balanced with each other, thereby making it possible to perform a high-frequency driving with a switching current having less ripple. Also, since the power source regeneration operation is performed in a long time in the case where the switching current level is reduced, it becomes possible to quickly reduce the current level down to a desired level.
