Abstract: An opening/closing body control device continues an as-needed operation where the opening/closing body is controlled in response to the operation instruction signal even when an abnormality in an opening/closing position of the opening/closing body is detected, continues opening and closing the opening/closing body until it is determined that the abnormal state in the opening/closing instruction signal is confirmed even when an abnormality in the opening/closing instruction signal is detected during the as-needed opening/closing operation, and stops opening and closing the opening/closing body the abnormal state in the opening/closing instruction signal is confirmed. The confirmation time at the presence of the opening/closing position abnormality is shorter than that at the absence of opening/closing position abnormality.

Abstract: Accurate driver state determination achieving safety is enabled without being affected by differences between individual drivers. A driver state determination apparatus for determining a driver state, such as distracted driving, includes a calculator that determines a direction of a vehicle driver's face or gaze based on first sensing data output from a first sensor and including an image of the driver, and calculates statistical information about a direction in which the driver looking straight ahead retains his or her gaze with respect to a forward direction of a vehicle. A correction unit corrects the determined face or gaze direction of the driver with respect to a reference direction defined as the forward direction of the vehicle based on the statistical information. A determiner determines a driver state based on a deviation of the corrected face or gaze direction of the driver from the reference direction.

Abstract: A switch assembly includes a switch housing defining an interior volume, and a switch actuator slidably retained within the switch housing. Travel in a first direction by the switch actuator compresses a resilient dome switch and a hard mechanical stop limits a full extent of return travel by the switch actuator within the switch housing. A resilient retention post, formed in a resilient switch pad that includes the resilient dome switch, for example, has a length terminating in a flanged tip that captures the switch actuator and thereby defines a restricted extent of return travel by the switch actuator. The restricted extent of return travel is less than the full extent of return travel, to prevent the resilient dome switch from springedly urging the switch actuator into contact with the hard mechanical stop.

Abstract: In a target object detection apparatus, an LD module projects laser light onto a predetermined range, and a PD module receives the reflected light from a target object, and outputs a light reception signal. Based on the light reception signal, an object detector detects presence or absence of the target object and a distance from the target object detection apparatus to the target object, and a dirt detector detects presence or absence of dirt on an optical window. The dirt detector detects, based on the light reception signal, dirt levels in units of segments in a detection field-of-view of the target object detection apparatus, and also detects a density and an extent of the dirt, based on the dirt levels. A controller causes an interface to notify a vehicle-side ECU of the result of detection as to the dirt.

Abstract: A target detecting device scans a predetermined range with light emitted from a light emitter, guides the reflected light from a target to a light receiver, and detects the target and dirt on an optical window provided on a case according to the light reception state of the light receiver. Operation patterns of the light emitter and the light receiver differ between target detection and dirt detection, and target detection and dirt detection are separately performed. For example, in a predetermined range scanned with light by a target detecting device, the target detecting device detects dirt on the optical window in a region overlapping with a target detection region of adjacent target detecting device, and detects a target in the other regions.

Abstract: Safe detection of an external load attached to an AC power outlet of a power supply stands out as one advantage of the power supply apparatus and method contemplated herein, although other advantages flow therefrom. Not least among the other advantages are a simplicity of design offering an economical and robust mechanism for detecting external loads. The contemplated mechanism relies on the application of a DC voltage to one electrical phase of the AC power outlet and the coupling of that voltage to the other electrical phase of the AC power outlet through an interconnecting resistor. With both phases respectively coupled to voltage divider circuits nominally matched in value, the divided down voltages measured from the respective phases will differ in dependence on the relative size of the interconnecting resistor and the resistive value of any load attached to the AC power outlet.

A magnetic detection unit outputs a detection signal which changes according to a change in a magnetic field. A magnetic pole direction calculation unit calculates a magnetic pole direction of a rotor based on the detection signal. A current detection unit detects a current flowing through each multiphase coil.

A direction correction amount calculation unit calculates a direction correction amount based on a direction and magnitude of the rotating magnetic field calculated by the rotating magnetic field vector calculation unit. A magnetic pole direction correction unit corrects the calculated magnetic pole direction by using the calculated direction correction amount calculated.
