An electric power is surely supplied to a load even if an abnormality is generated in a switching control circuit, which controls a switching part that switches electric connection between a power supply and the load of a vehicle. The switching control circuit controls a state of a contact of a keep relay that switches the electric connection between the power supply and the load. A monitor circuit monitors existence or non-existence of the abnormality of the switching control circuit. When detecting the abnormality of the switching control circuit, the monitor circuit transmits a reset signal in order to reset a state of the switching control circuit. When receiving the reset signal from the monitor circuit, an abnormal-time connection circuit transmits a connection signal to a coil of the keep relay to bring a movable contact into contact with a contact. For example, the present invention can be applied to a power-supply control device for the vehicle.

Power-supply control device

An in-vehicle instrument control device, that controls a power source of a plurality of in-vehicle instruments operated by power from the power source provided in a vehicle, includes a plurality of operation units to operate the respective in-vehicle instruments; and a plurality of power source control units that are each provided between the operation unit and the power source, and the in-vehicle instrument, and each supply the power from the power source to the in-vehicle instrument when a predetermined operation signal is inputted from the operation unit.

An imaging device capable of suppressing the complexity of a constitution and reducing the dispersion of brightness sensitivities of individual solid imaging elements to the temperature includes a solid imaging element, a temperature sensor for detecting the temperature, and a temperature monitor for detecting the temperature of the solid imaging element with an output signal of the temperature sensor. On the basis of this detection result, the control values corresponding to the temperatures at different times are set in the register of the voltage control circuit. In accordance with the control values of the register, the voltage control circuit controls reset voltages to be fed to pixel cells.

Imaging device, and control method for solid imaging element

An antenna failure detecting device that can avoid erroneous detection and use a reference voltage of relatively low precision is includes a switch that can short-circuit both the ends of a resistor inserted in a common line. Only when the voltage between both the ends of the resistor is detected, the switch is 'disconnected' (off), and when the voltage between both the ends of the resistor is not detected, the switch is 'connected' (on). Therefore, the effect of the resistor can be excluded, and the unnecessary loss of the common line at the non-detection time can be eliminated. Furthermore, the resistor is used only at the failure detection time, and thus the resistance value of the resistor can be freely increased. Therefore, a large voltage between both the ends can be taken out, and the permissible range of the reference voltage for failure judgment can be broadened, so that a reference voltage of low precision can be used.
