    • A method and apparatus (206) for time-scale modification of an input signal comprises the steps and a device that performs the steps of digitizing the input signal for analysis, storing the input signal in a memory and then dividing the input signal into time frames (250). The method and device then determines a difference in the short-term frequency spectrum between adjacent time frames (252 and 254) to provide a first speed factor (S1) and the input signal is time-scaled (208) in accordance with the first speed factor. Optionally, a second speed factor (S2) can be determined from the percentage of silence (262) observed within the input signal and the input signal can then be time-scaled in accordance with the first and second speed factors to provide a given quality of reconstructed speech.

    • An automatic control system for controlling the firmness of a fluid supported mattress (14) of a bed assembly (10). The control system includes a motorized fluid pump, a control unit (44) for operating the pump to adjust the firmness of the air mattress (14), a hand held remote control unit (42) for actuating the control unit (44), and a transceiver system for transmitting information signals between the hand held unit (42) and the control unit (44). The air control system provides for independent control of both bladders (30, 32) in a two bladder air mattress (14) from a single unit (44), and allows a user to consistently set the firmness of each mattress air bladder (30, 32) to a desired value. The air control system includes an air pump specially designed to minimize transmission of motor noise into the environment.

    • The service area of a radio selective call receiver is easily switched. When the movement information of the radio selective call receiver is registered in the radio call device of the service area in which the receiver is present, a call request is transferred to the radio call device of a designated service area. The radio call device transmits the receiving condition switching information of the radio selective call receiver as a radio signal. The receiver receives the signal and switches its receiving condition. Because the movement information and switching information each include information about the designated switching time, the transfer or switching is automatically performed when the designated switching time comes. Alternatively, in a system that the receiving condition is prefixed in every service area, the radio selective call receivers each have multiple call numbers, and each receiver sets one call number suitable for the service area where the receiver exists, the receiving condition and switching designating time are set in every service area. The receiving conditions include the radio channel, transmission system, receiver identification number, etc., and these conditions can be set separately or combinedly. The switching state and switching time can be displayed for confirmation. When the designated switching time comes, the receiving condition is automatically switched. The user is informed of the switching. The switching operations which have been made whenever the radio selective call receiver moves into another service area are collectively performed at arbitrary time. The receiving condition switching procedure is thus simplified and erroneous setting is avoided. Since the receiving conditions can be set at once in accordance with the schedule of the day, forgetting of switching and troubles can be eliminated.
    • 无线电选呼接收机的服务区容易切换。 当无线电选呼接收机的移动信息被登记在接收机所在的服务区的无线电呼叫装置中时,呼叫请求被传送到指定服务区的无线电呼叫装置。 无线电呼叫装置发送无线电选呼接收机的接收条件切换信息作为无线电信号。 接收器接收信号并切换其接收状态。 由于移动信息和切换信息各自包括关于指定切换时间的信息,所以在指定切换时间到来时自动执行传送或切换。 或者,在每个服务区域中接收条件为前缀的系统中,无线电选呼接收机各具有多个呼叫号码,并且每个接收机设置适合于存在接收机的服务区域的一个呼叫号码,接收条件和切换指定 每个服务区都设置时间。 接收条件包括无线电信道,传输系统,接收机识别码等,这些条件可以单独设置或组合设置。 可以显示切换状态和切换时间以进行确认。 当指定的切换时间到来时,接收状态自动切换。 通知用户切换。 当无线电选呼接收机移动到另一个服务区域时已经进行的切换操作在任意时刻被集体地执行。 因此,接收条件切换过程被简化并且避免了错误的设置。 由于接收条件可以根据一天的时间表一次设定,所以可以省略切换和故障的忘记。
