A sewing machine includes a sewing unit including a sewing machine motor, a single terminal for connecting a foot controller to the sewing machine, and a controller that controls the sewing unit. When the foot controller is not connected to the sewing machine, the single terminal allows connection of an external device to the sewing machine. The controller performs: a speed-data receiving operation to receive speed data from the foot controller connected to the sewing machine via the single terminal for controlling a sewing speed; a speed-control operation to control the sewing machine motor in accordance with the speed data received in the speed-data receiving operation; an input-data receiving operation to receive input data from the external device connected to the sewing machine via the single terminal; and a data-outputting operation to output output data to the external device via the single terminal.

A power receiving device includes a storage and a computer. The computer stores a first operating condition indicating a past operating condition of the power receiving device in the storage. The computer detects a power supplying capacity within which a power supplying device can supply power and identifies a specific value in relation to the first operating condition from the storage. The computer sets an incoming power based on both the detected power supplying capacity and the identified specific value, thereby allowing the power supplying device to send the set incoming power.

The disclosure discloses an electronic apparatus including a charging device, a plurality of operation mechanisms, and a CPU. The CPU is configured to execute an information acquisition process, a voltage decision process, and a charging control process. In the information acquisition process, capacity-related information corresponding to a charging capacity required for operation of the operating mechanisms is acquired. In the voltage decision process, a charge stop voltage is decided in accordance with the capacity-related information acquired. In the charging control process, the charging device is controlled to stop the charging process by using as a trigger an attainment of the charge stop voltage decided after start of the charging process.

Electronic device

A power source circuit includes a first converter, a second converter, a switch and a controller. The switch is configured to switch between a first state and a second state, in which in the first state, a first voltage is not supplied to the second converter whereas in the second state, the first voltage is supplied to the second converter. The controller controls the switch to change the first state to the second state in response to detection of the change in a first current flowing in a first load. The second converter is configured to convert a battery voltage of a battery to a second voltage lower than the battery voltage when the switch switches to the first state and convert the first voltage to the second voltage lower than the first voltage when the switch switches to the second state.
