Abstract: A malfunction detection method detects a malfunction in an electronic control device. The electronic control device includes a normal power supply terminal connected to a normal power supply mounted on a vehicle, a starting power supply terminal connected to a starting power supply, a controller activated by supply of a normal voltage, and a wake-up circuit having a wake-up switch to open and close a power supply path from the normal power supply terminal to the controller. The wake-up circuit turns on the wake-up switch when a starting voltage input to the starting power supply terminal is equal to or greater than an ON threshold. The malfunction detection method includes determining by the controller that the wake-up switch has an ON sticking malfunction when the normal voltage is equal to or greater than a threshold and the starting voltage is less than the ON threshold.

Abstract: The present invention relates to an information processing apparatus, an information processing method, and a program capable of simplifying an interrupt processing and reducing a time necessary to the interrupt processing. An interrupt generation unit 140 generates an interrupt signal. An interrupt status holding unit 142 stores an interrupt status showing a cause of generation of the interrupt signal. An interrupt status supply unit 141 supplies an interrupt status stored by an interrupt status holding unit to a RAM and causes the RAM to store it. A CPU executes a predetermined processing in response to the interrupt status stored to the RAM. The present invention can be applied to, for example, a network card.

Abstract: A broadcast receiver includes a controller that detects a reception log of a receiving unit and that records the reception log in a reception log memory. The reception log includes at least the reception channel, reception start time, and reception end time. Periodically an audience member connects the broadcast receiver to a general-purpose computer. The general-purpose computer transmits the reception log data recorded in the reception log memory with a receiver ID written in a ROM through a telephone line over a communication network, such as the Internet. A person who computes viewing/listening information obtains the reception log data and receiver ID from the communication network and computes viewing/listening information, such as a program rating. Instead of providing the broadcast receiver with the reception log memory and a computer interface, a removable storage unit with a computer interface can also be used.
