    摘要： A navigation system is provided. A medium insertion port is disposed on the front surface of a main unit and a portable recording medium is loaded into or unloaded from the main unit through the medium insertion port. A display unit is disposed on the front surface of the main unit and can move between a closed position where the medium insertion port is covered and an opened position where the medium insertion port is exposed. A limitation section limits the movement of the display unit to the opened position. A limitation removing section removes the limitation by the limitation section. An operation section receives an operation on the navigation system. The operation section can receive an operation other than an operation to be intrinsically received by the operation section. The limitation removing section removes the limitation by the limitation section when the operation section receives the operation other than the operation to be intrinsically received.

    摘要： A controller (2) of an air-fuel-ratio sensor (100) includes a control unit (10), a voltage-abnormality detecting unit (20), and a short-circuit-abnormality detecting unit (30). The control unit (10) controls a current and a voltage of a gas sensor element (1) through a plurality of terminals (T) connected with the gas sensor element (1). The voltage-abnormality detecting unit (20) changes, when at least one of voltages of the plurality of terminals (T) is out of a predetermined range, a voltage level of an output voltage (Vo). The short-circuit-abnormality detecting unit (30) causes, when the voltage level of the output voltage (Vo) changes from a first voltage into a second voltage, a control unit (10) to perform for a predetermined time a protective operation that suppresses currents from the control unit (10) to the plurality of terminals (T), and detects, when the voltage level of the output voltage (Vo) is the second voltage after the protective operation is released, a short-circuit abnormality.

    摘要： An engine control apparatus controls an engine. The engine control apparatus includes a stack detecting unit, a count processing unit, a stack value storage control unit, and an abnormality determination unit. The abnormality determination unit determines that a sensor has a stack abnormality when a count value by the count processing unit becomes equal to or more than an abnormality determination threshold. When maximum value of the detected value of the sensor detected during a determination period is lower than a value stored in a stack value storage unit and a stack state has not been detected by the stack detecting unit during the determination period, the count processing unit does not count up a counter and does not reset the counter.

    摘要： There is provided a radar apparatus. A derivation unit derives this time-decided transverse distance of the target of this time processing, by filtering, with a predetermined filter constant, this time transverse distance of paired data of this time processing, and a predicted transverse distance. A change unit changes, when the transverse distance of an object moving target moving a in a traveling direction of a vehicle mounted with the radar apparatus and the transverse distance of a specific target satisfy a predetermined relation, the filter constant for filtering this time transverse distance and the predicted transverse distance of the object moving target so that a reflection amount of this time transverse distance is reduced in comparison to before the change.
