摘要： A drive circuit supplies a charging current via a charging path to drive the control terminal of a voltage-controlled switching device, with a resistor and a switching device being connected in series in the charging path. A control circuit in an integrated circuit of the drive circuit operates an internal switching device such as to selectively enable/interrupt the charging current and to regulate the voltage drop across the resistor to a fixed value. The switching device connected in the charging path can be readily changed from the internal switching device to an external switching device, in accordance with the operating requirements of the driven switching device.

摘要： A failure detection device for a vehicle speaker includes a signal generator, an amplifier, a coupling capacitor, a supply circuit, a detection circuit, and a determination section. The signal generator generates a sound signal corresponding to sound outputted from the speaker. The amplifier amplifies the sound signal. The capacitor supplies the amplified sound signal to the speaker. The supply circuit supplies a direct-current test current to the speaker so that the test current does not flow through the capacitor by applying a test voltage to the speaker. The test voltage is higher than a voltage of the sound signal. The detection circuit detects a terminal voltage of the speaker. The determination section determines whether at least one of an open-circuit and a short-circuit occurs in the speaker based on the terminal voltage during application of the sound signal to the speaker.

摘要： An abnormal combustion detection apparatus detects an abnormal combustion of an internal combustion based on a vibration waveform from a vibration sensor attached to the internal combustion engine. A gain circuit of the apparatus amplifies or attenuates the vibration waveform from the vibration sensor, an AD conversion circuit converts a waveform provided by the gain circuit to digital data, and a gain switching unit switches a gain of the gain circuit from a small gain value to a large gain value at a gain switch timing. The gain switching unit separates a large abnormal combustion from a small abnormal combustion in an abnormal combustion determination period for maximizing a dynamic range of an AD conversion circuit and for securely detecting a change of waveform amplitude in case of gain switching in an abnormal combustion detection operation.

摘要： A certain ECU transmits a reference message for requiring the other ECUs to transmit data. After transmission of the reference message, each of all the ECUs transmits priority information of its transmit message onto a communication bus, and then detects whether some priority information transmitted from the other ECUs has a higher priority than its own transmitted priority information. If there is detected no priority information of a higher priority than its own transmitted priority information, it transmits a message associated therewith, and then is prohibited to transmit data of the same priority until receiving a next reference message.

摘要： There is provided a communication system that includes master and slave communication ECUs. The master communication ECU sends a clock signal to a clock communication line, with which the communication ECUs synchronize with each other when sending and receiving data. The master and slave communication ECUs then receive the clock signal through the clock line. The ECUs use the received clock signal as a reference timing, which is designated as a transmission/reception reference, and send or receive data to/from data communication lines.
