    • Razor handles are provided for razors having a battery-powered functionality. Methods of manufacturing such handles are also provided. In one implementation, the handle comprises: a load comprising a motor coupled to a power source; a user-operable switch for controlling energy flow between the power source and the load; a control logic; an arming circuit to prevent the user-operable switch from causing drainage of the power source; and a locking circuit that receives a switch signal from the user-operable switch and an arming signal from the arming circuit, wherein the locking circuit outputs a motor control signal to the control logic in response to the states of the switch signal and the arming signal, wherein the arming circuit comprises a timer for changing the state following lapse of a time interval and an arming switch having a first state and a second state.
    • 为剃须刀提供剃须刀手柄,具有电池供电功能。 还提供了制造这种手柄的方法。 在一个实施方式中,手柄包括:负载,其包括联接到电源的马达; 一个用户可操作的开关,用于控制电源和负载之间的能量流动; 控制逻辑; 用于防止用户可操作的开关引起电源的引流的布防电路; 以及锁定电路,其接收来自用户可操作开关的开关信号和来自布防电路的布防信号,其中锁定电路响应于开关信号和布防信号的状态向控制逻辑输出电动机控制信号 其中所述布防电路包括用于改变经过时间间隔的状态的定时器和具有第一状态和第二状态的布防开关。
