A command input system, includes: 1) an infrared camera for picking up an image of a sensing area, with which defines a certain part as a back face; 2) an extractor for extracting, based on an image data of the image picked up by the infrared camera, at least one of the following: a) a configuration of a hand, and b) a movement of a hand; and 3) a temperature adjustor for adjusting at least one of a hand temperature and a back face temperature so as to increase a difference between the hand temperature and the back face temperature.
摘要:
At either of the two terminals of each of a plurality of cells constituting a battery pack, a detection terminal is provided, and malfunction detection circuits each provided in correspondence to one of the cells each detect a malfunction of the corresponding cell based upon the voltage between the detection terminals. When shorting circuits are engaged in operation to short detection terminals corresponding to alternate cells from each other, a disconnection having occurred between a given cell and a corresponding detection terminal is detected based upon signals output from the malfunction detection circuits.

An integrated drive motor unit which is integrally constituted of a motor, an inverter and a reducer differential unit arranged in a row, and a frame member. The reducer differential unit is connected to an output shaft of the motor, and distributes torque of the motor to a pair of axles, one of which passes through the inverter. The frame member constitutes a part of the motor and a part of the reducer differential unit, and has a portion surrounding the axle passing through the inverter. The inverter is disposed outside the frame member.
摘要:
A malfunction detection circuit that detects a cell malfunction alternately outputs the results of an overcharge detection executed during an overcharge detection period and the results of an over-discharge detection executed during an over-discharge detection period through time sharing based upon a clock signal. When the cell is in the normal range, the signal level of the signal output during the overcharge detection period is different from the signal level of the signal output during the over-discharge detection period. Thus, in the malfunction detection, the signal generated when an overcharge malfunction has occurred in the cell can be distinguished from the signal generated when an over-discharge malfunction has occurred in the cell.

A non-contact information input device is provided that can easily and reliably use simple image processing to input information indicated by the shape of a user's hand. The non-contact information input device is configured to detect a user's hand using an imaging section, and to select an operation mode based on a shape of the hand. Then, a distance detecting section of the non-contact information input device is configured to detect a distance from the hand to the imaging section and adjust a parameter used in the operation mode in response to the distance if the parameter is adjustable. Thus, the image processing load is reduced and the parameter is easily and reliably adjusted by adjusting the parameter in the selected operation mode based on the distance detected by the distance detecting section.
摘要:
A drive unit for an electric vehicle is comprised of a motor, an inverter which supplies alternating current electric power to the motor, a speed reducer which is connected to the motor, and a cooling system which cools the motor, the inverter and the speed reducer. The speed reducer reduces a revolution speed of a mechanical output of the motor. The cooling system comprises a heat exchanger at which first refrigerant for receiving heat of at least one of the motor and the inverter receives heat of second refrigerant for receiving heat of at least one of the motor and the speed reducer.
