    Abstract: An information device makes a payment with a payment terminal through a contactless communication, using amount data of an electronic purse function of a mobile device. The mobile device with the electronic purse function permits the information device to be used for performing payment processing with the payment terminal, using amount data of the electronic purse function of the mobile device. A wearable information device includes an image taking unit configured to take an image of an object in the direction of line of vision of a user, and notifies the information device of the presence or absence of the information device in a taken image. The information device makes a payment with the payment terminal through a contactless communication based on the notification from the wearable information device of the presence or absence of the information device.

    Abstract: A driving device includes a switching regulator and a timing controller. The switching regulator includes a switching element, a smoothing circuit including an inductor connected to the switching element, and a controller that turns on/off the switching element. The switching regulator converts input voltage to output voltage as output of the smoothing circuit by turning on/off the switching element. The timing controller controls the controller to operate and stop operating. The controller performs constant current control by feeding back inductor current, generating a PWM signal based on the fed-back current and a target value, and outputting the PWM signal to the switching element so that the inductor current approximates to the target value. When performing the constant current control, the controller sets the target value to a value different from a reference target value for a steady period.

    Abstract: Disclosed is a charge protection circuit including: a switch that switches between allowing and not allowing power supply from an external power source to a charging circuit that supplies power for charging a rechargeable battery; a detector that detects at least one of a current flowing from the charging circuit to the rechargeable battery and a voltage between two electrodes of the rechargeable battery; a determiner that determines whether a detection result of the detector is abnormal; and a controller that, in response to the determiner determining that the detection result of the detector is abnormal, causes the switch to switch to an interrupting state so as to interrupt power supply to the charging circuit.

    Abstract: A driving device includes a power source that converts input power to output power, first and second capacitors connected to an output of the power source, a load selector, and a capacitor selector. The load selector opens/closes circuits of first and second loads connected to the output of the power source to alternately close these circuits such that the second-load circuit is closed after the opening of the first-load circuit. The capacitor selector opens/closes circuits of the first and second capacitors to alternately close these circuits such that the first-capacitor circuit is closed in synchronization with the closing of the first-load circuit, and such that the second-capacitor circuit is closed in synchronization with the closing of the second-load circuit. The capacitor selector opens the first-capacitor circuit after the opening of the first-load circuit.
