    Abstract: 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.

    Abstract: A battery-powered portable tool (1) and/or a battery pack (174; 174′) connected thereto contain(s) a high-temperature measurement circuit (61, 62, 64; 64-67), a low-temperature measurement circuit (61, 64; 64-66), and a switching apparatus (63; Q 1, Q 2) for selecting and/or outputting a signal from (i) the low-temperature measurement circuit when an output value of the high-temperature measurement circuit enters an abnormal range or (ii) the high-temperature measurement circuit when an output value of the low-temperature measurement circuit enters an abnormal range, which are powered by at least one all-solid-state battery (12, 14, 16, 18) provided in the battery pack. Such an arrangement makes it possible to efficiently make use of the at least one all-solid-state battery that is usable over a wide temperature range, whereby the battery-powered tool becomes usable over a wider temperature range than known battery-powered tools.

    Abstract: A hand-held power tool includes a motor having a stator and a rotor, the motor being configured to rotate the rotor at a speed of at least 40,000 rpm, an output shaft directly driven by the rotor, a tool accessory shaft configured to support a tool accessory, and a two-stage speed reducing transmission operably connecting the output shaft to the tool accessory shaft. The two-stage speed reducing transmission is configured to drive the tool accessory shaft at a rate less than the rotor speed, for example, at a rate less than or equal to 37.5% of the rotor speed.
