Abstract: An electronic device includes: a first processor; a load that operates with power supplied by a rechargeable battery; and a first sensor that obtains information on an output voltage of the rechargeable battery. The first processor determines whether the rechargeable battery is in a low usage state with regard to power supply by the rechargeable battery. Based on the information obtained by the first sensor, the first processor determines a degree of decrease in the output voltage over a period of time during which the rechargeable battery is determined to be in the low usage state. Based on the determined degree of decrease, the first processor detects a deterioration of the rechargeable battery.

Abstract: An input terminal connected to both a terminal of the first device outputting a signal including a period of a low voltage greater than or equal to a predetermined period and a terminal of the second device outputting a periodic signal alternately repeating a high voltage and a low voltage less than the predetermined period via one signal line is included. When a signal input to the input terminal includes a period of a low voltage greater than or equal to the predetermined period, it is determined that a signal output from the first device is input.

Abstract: An electronic device includes first and second processors, and first and second display units. While the first and second processors cooperate with each other and perform a display operation including a time display, the first processor can be set to a normal mode, a low power mode in which a power consumption is lower than a power consumption in the normal mode, or a pause mode in which a power consumption is lower than the power consumption in the low power mode, and the first processor is stopped. In the normal or low power modes, the first processor controls such that the first display unit displays a time, and the second processor controls such that the second display unit does not display a time. In the pause mode, the first display unit is turned off, and the second processor controls such that the second display unit displays a time.

Abstract: A wearable information device is configured to store device identifying information used for identifying the information device registered in advance, to confirm whether or not a taken image, in which an object in a direction of line of vision of a user is taken, shows the information, by image analysis based on the stored device identifying information, and to notify the information device of a result of the confirmation. The information device is configured to execute a predetermined function on the basis of the result of the confirmation of the information device notified from the wearable information device.
