Abstract: A target detection device according to an embodiment includes an acquisition unit and a determination unit. The acquisition unit acquires positional data of a target in a plurality of sensors and sensor characteristic data that indicate a positional characteristic of detection accuracy in the plurality of sensors. The determination unit determines identity of a target object that is a detection object in each sensor based on positional data and sensor characteristic data that are acquired by the acquisition unit.

Abstract: An optical module includes a support, a movable part supported by the support so as to be swingable about an axis, a mirror provided to the movable part, a drive coil provided to the movable part, a temperature monitoring element provided to the support, and a magnet that generates a magnetic field acting on the drive coil. The support is thermally connected to the magnet.

Abstract: A motor controller includes control systems that control actuation of a motor. Each control system includes a drive circuit and a calculation unit. The calculation unit of each control system is connected to an independent rotation angle sensor. The calculation units include master and slave calculation units. The master and slave calculation units control actuation of the corresponding drive circuit based on a current instruction value calculated by the master calculation unit and a detection result of the rotation angle sensor connected to the master calculation unit. When the detection result of the rotation angle sensor connected to the master calculation unit is abnormal, the master and slave calculation units each use a detection result of the rotation angle sensor connected to the slave calculation unit to control the actuation of the corresponding drive circuit.

Abstract: This invention intends to provide a vehicle-mounted driving recorder that can facilitate an after-the-fact analysis on not only situation data at a time of an accident but also situation data at a time of a hiyari-hatto and that can contribute accident prevention. The vehicle-mounted driving recorder comprises a data receiving section that receives situation data indicating behavior, a surrounding situation, and an operating situation of a vehicle and a data administration section that classifies the situation data into one of predetermined multiple categories based on contents of the received situation data and stores the classified situation data in a situation data storage section specified in a predetermined area of a memory.

Abstract: A vehicle behavior analysis system performs an analysis of vehicle operation by displaying behavior data in an organized and analyzed form. A vehicle behavior data collecting unit records information on the vehicle's driving as behavior data and an analysis unit analyzes a recorded content of the vehicle behavior data collecting unit. A recorded data unit obtaining part obtains the recorded data units recorded in a memory of the vehicle behavior data collecting unit and a displaying part displays the content concerning at least a predetermined item among the contents shown by obtained each recorded data unit in a form of a table sectioned for each recorded data units and arranged at a side of the analysis unit, and a risk degree calculated based on the content shown by each recorded data units is contained in the predetermined item displayed by the displaying part.

Abstract: A leg shocking device for pedestrian protection test comprising a bendable knee part, a thigh part and a lower thigh part, both of which have a predetermined length connected to the knee part, the thigh part and the lower thigh parts formed of a deformable cylindrical body having a plurality of bone outer members connected to each other in a longitudinal direction and a bend-deformable bone core member inserted into and secured to the deformable cylindrical body of each of the thigh part and lower thigh part and having a plurality of distortion gauges mounted thereon and each of the bone outer members having an accelerometer provided thereon for measuring the acceleration occurring on the corresponding bone outer member whereby the bending characteristic of a person can be faithfully provided.

Abstract: A flow rate measuring apparatus capable of accurately measuring a flow rate of fluctuating fluid. A mode setting circuit selectively sets any one of a plurality of predetermined transmission modes different in transmission timing. The mode setting circuit sets any one of a first transmission mode which permits an ultrasonic wave to be transmitted at a predetermined timing for every period of a flow waveform of exhaust gas, a second transmission mode which permits an ultrasonic wave to be transmitted at a timing shifted by a predetermined time for every period of the flow waveform of the exhaust gas and a third transmission mode which permits an ultrasonic wave to be transmitted at predetermined intervals.

Abstract: In an engine using fuel of low startability, there are provided an ultrasc atomizer and a fuel injection valve arranged on a suction pipe of the engine, and a catalyzer unit mounted between said ultrasonic atomizer and a fuel injection valve. When the engine is started, the fuel atomized by the ultrasonic atomizer is supplied to the catalyzer unit to generate an intermediate product of high volatility. After the engine has been started, fuel is supplied through the fuel injection valve. When a fuel is passed through the catalyzer unit such as methanol fuel, aldehyde is generated by a decomposition reaction, reforming reaction, partial oxidation reaction, etc., or dimethylether is generated by a dehydrating condensation reaction. By supplying this intermediate product of high volatility to the engine, the startability of the engine at low temperatures is improved.

Abstract: In an impact absorbing device for protecting an occupant of a vehicle in the event of a collision, a seat belt for the occupant has an anchor for fixedly mounting on the occupant's seat and adapted to hold the occupant at an optimum angle and in an optimum position. An energy absorbing mechanism is connected between the seat and the floor of the vehicle or a fixture on the floor of the vehicle. The energy absorbing mechanism is constructed to permit a resisted linear movement of the seat, longitudinally of the vehicle, in the event of a collision, so as to absorb the impact forces which would otherwise be applied to the occupant.
