A thermoelectric system includes a pair of substrates, a plurality of semiconductor elements, and first, second, and third terminals. The semiconductor elements are positioned between the opposing faces of the substrates, and the semiconductor elements comprise at least two groups of dissimilar semiconductor elements. The semiconductor elements are electrically coupled in series by conductor elements arranged so the two groups of dissimilar semiconductor elements are connected in an alternating pattern. The first, second and third terminals are connected to the conductor elements with the third terminal positioned between the first and second terminals. The electrically coupled semiconductor elements comprise first nodes and second nodes. The first and second nodes emit or absorb heat according to electric current flowing through the semiconductor elements, and impedance of the thermoelectric system is controlled by switching the switch.

A radio frequency energy management system includes a number of battery control modules and/or a control unit that are configured to exchange battery operating parameter/performance information and control signal by radio frequency. Each battery control module includes one or more sensing elements to measure one or more operating parameters of a respective battery, and at least one device selected from the group including a radio frequency receiver, a radio frequency transmitter, a memory device, a controller, control devices, a signal blocking device, and combination thereof. The control unit is configured to monitor and control the operating parameters of the batteries and includes a radio frequency receiver and a radio frequency transmitter. The control unit evaluates data transmitted from battery control modules according to a predetermined control system program, and transmits a predetermined control command to one or more battery control modules to achieve battery equalization and battery thermal management. The energy management system can also include one or more devices for identifying the relative location of a battery control module in the system, and an interface to permit communication with battery control modules by another device independent of the control unit. Radio frequency signals are transmitted between the control unit and each battery control module, and between battery control modules, without additional wiring, thereby eliminating the disadvantages of wired-type systems.
摘要:
A radar system is described for use in vehicular applications. The radar system is particularly suited to backup warning systems and lane-change warning systems. The radar minimizes many of the problems found in the prior art by providing programmable delays and programmable gain. The radar uses a range search algorithm to detect and sort targets at various ranges within the field of view of the radar. Each target range corresponds to a particular delay and gain setting. The radar searches for targets at the various ranges by running a target search algorithm. For each target range, the search algorithm causes the proper time delay and gain setting. Targets within the selected range are detected and catalogued. Speed of the targets is obtained through Doppler processing. A display is used to warn the driver of the vehicle of the presence of targets at the various ranges. The warning may be visual and/or audible. When used in a lane-change system, issuance of an audible warning is based on the speed of the vehicle.
