An apparatus includes a first authentication unit that performs an authentication process for determining whether an external apparatus is a predetermined external apparatus, a second authentication unit that performs an authentication process for determining whether a battery connected to the external apparatus is a predetermined battery, and a control unit that permits the battery to be discharged but restricts the battery from being charged regardless of whether the battery is the predetermined battery, in a case where the external apparatus is not authenticated as the predetermined external apparatus.

Electronic apparatus and control method

An electronic device includes a first voltage conversion unit, a second voltage conversion unit, and a control unit. The first voltage conversion unit generates a first voltage from power supplied from a first power supply or a second power supply. The second voltage conversion unit generates a second voltage, which is lower than the first voltage, from power supplied from the first power supply or the second power supply. The control unit controls a process of supplying power, supplied from the first power supply, to the first voltage conversion unit and a process of supplying power, supplied from the second power supply, to the second voltage conversion unit, in a case where a predetermined condition is satisfied.

Electronic device and control method

An electronic apparatus connectable to an external electronic apparatus and storing at least one power supply for operating the external electronic apparatus includes a connection interface that is connected to the external electronic apparatus, and at least one processor configured to control the electronic apparatus. Power of the at least one power supply is supplied to the external electronic apparatus via the connection interface. The at least one processor controls the external electronic apparatus by using power received from the external electronic apparatus via the connection interface.

Electronic apparatus and accessory system

A device includes a load test unit that determines whether to permit startup of the device using power of a battery supplying power to the device, and a control unit that starts up the device in a case where it is determined to permit startup of the device using the battery and a first voltage is requested of a power supply apparatus to restrict power received from the power supply apparatus. The control unit cancels the restriction of the received power in a case where a notification of completion of connection is received from the power supply apparatus, after the device is started up and a second voltage is requested of the power supply apparatus.

Device and control method

An electronic device includes a connection unit and a control unit. The control unit enables a power supply path for supplying power from a first battery connected to an external device to the electronic device and enables a power supply path for supplying power from a second battery connected to the external device to a predetermined functional unit of the external device, in a case where the first battery or the second battery connected to the external device is not charged. The control unit disables a power supply path for supplying power from the second battery connected to the external device to the predetermined functional unit and enables a power supply path for supplying power from the electronic device to the first battery or the second battery, in a case where the first battery or the second battery connected to the external device is charged.

A power receiving apparatus includes a power receiving unit and a control unit. The power receiving unit receives a first power from a power supply apparatus via a connection unit. The control unit determines whether or not authentication information including identification information of the power supply apparatus is authentic, and determines whether or not the power supply apparatus has passed a compliance test based on the identification information. The power receiving unit is allowed to receive a second power greater than the first power, in a case where the authentication information is authentic and the power supply apparatus has passed the compliance test.

When the first electrical conductor overlaps one of the three or more detection electrodes, the one detection electrode and the first electrical conductor are capacitively coupled. When the position of the first electrical conductor has changed in accordance with movement of the operation member, it is determined, based on the capacitance of each of the three or more detection electrodes after the change, that the first electrical conductor has moved in a direction from a first detection electrode judged to have decreased the capacitance to a second detection electrode judged to have increased the capacitance.

An input apparatus capable of improving detection sensitivity in detecting operations using a capacitive sensing method. An operation member is operated to change the positional relationship between a substrate and a conducive member. In the conductive member, a first part whose facing area facing an earth electrode of the substrate does not change even when the positional relationship between the substrate and the conducive member changes, and second parts whore facing area facing detecting electrodes of the substrate changes in response to a change in the positional relationship between the substrate and the conducive member are formed. The substrate or the conducive member is formed so that when the facing area of the second parts facing the detecting electrodes reaches the maximum, the facing area of the second parts facing the detecting electrodes can be equal to the facing area of the first part facing the earth electrode.
