    • A motor-driven appliance system in one aspect of an embodiment of the present disclosure includes a motor-driven appliance having a motor, at least one control circuit, and a communication device. The control circuit is configured to execute a process related to control of the motor-driven appliance. The communication device is configured to communicate with an external device. The control circuit is further configured to switch, when at least one predetermined sleep condition is satisfied, from an active mode in which the control circuit performs a normal operation to a sleep mode in which the control circuit stops part of the normal operation to thereby suppress power consumption; and to switch to the active mode when the communication device receives an external wakeup signal transmitted from the external device while the control circuit is in the sleep mode.
    • 本公开的实施例的一个方面的电动机具系统包括具有电动机,至少一个控制电路和通信装置的电动机具。 控制电路被配置为执行与电动机构的控制有关的处理。 通信设备被配置为与外部设备进行通信。 控制电路还被配置为当从控制电路执行正常操作的活动模式到满足正常操作的一部分的休眠模式时,在满足至少一个预定的睡眠条件时切换,从而抑制 能量消耗; 并且当控制电路处于睡眠模式时,当通信设备接收到从外部设备发送的外部唤醒信号时,切换到活动模式。
