A radar device having means for generating a carrier-frequency signal, means for shaping pulses, means for generating modulated radar pulses from the carrier-frequency signal, means for emitting modulated signals as radar pulses, means for receiving radar pulses and means for processing the received radar pulses. The means for receiving the radar pulses have an array including a plurality of antennas, the means for processing the radar pulses have means for dividing the signal power over at least two different reception branches. Means are provided for generating different directional characteristics in the various reception branches.

A wireless ad hoc pico network is formed by eyewear and other devices such as a computer, a bracelet and a telephone having similar transceivers mounted on them. The eyewear includes a frame and connected to the frame are two temples. Temples are connected to frame via hinges. Temples have a male portion of a connector incorporated in them. Female portion of the connector is made integral with the hinges. When the male portion is inserted in the female portion the temple is attached to the frame. The temples can be removed by pulling the connector apart, and a temple with different apparatus within it can be inserted in place of the removed temples. The temple may have co-molded within its body, an apparatus such as an audio device, a camera, a speaker, and a microphone, and a display device such as liquid crystal or an alarm.

A body suitable for motor vehicles, especially for passenger cars, comprises a passenger compartment with at least one supporting structure connected thereto, for example, for accommodating a driving unit and wheel guiding elements, the supporting structure being connected by a holder with the passenger compartment. To optimize this body, the supporting structure, having a connecting region to the passenger compartment, and a rear end region, is formed by an enveloping device of high strength, especially of fiberglass-reinforced plastic, the strength of which is optimized, the enveloping device surrounding the driving unit substantially all around.

This body structure is suitable for motor vehicles, especially for passenger cars and comprises a passenger compartment structure and at least one supporting structure adjoining thereon, for example, for accommodating a driving unit and wheel suspension elements. The supporting structure is connected to the passenger compartment structure through holding elements. To optimize the supporting structure, having a region connecting with the passenger compartment structure and a rear end region, the supporting structure is formed as an enveloping device of a high-strength, especially a fiberglass reinforced plastic, which is reinforced with a supporting device and surrounds the driving unit at least regionally, the enveloping device having several openings, each of which forms an access to the driving unit, and being provided with bearing mountings for the driving unit.

A method and an apparatus for operating a control unit for controlling operational sequences in a vehicle. When operational sequences are error-free, the control functions of the built-in control unit are partially or completely suppressed. This allows additional functions to be switched in and out, and also allows modification and/or adaptation of data and/or programs that are accessed by the control functions. In the specific operating instance of the application, a further control unit is insertable into the vehicle wiring harness between the first control unit and a sensor arrangement, collection, group or system and an actuator arrangement, collection, group or system. The control functions suppressed in the control unit are then performable by the second control unit. The control unit then performs only the measurement functions and actuation functions The sequence is initiated and controlled by integrated remote-control functions, which are in addition to the normal or other functions. Since the second control unit is accessible and is designed in accordance with its application task, the application of the control unit may be performed using control functions exported therefrom.
摘要:
A circuit arrangement for producing an output voltage with a first polarity with respect to a reference-earth potential from an operating voltage with a second polarity with respect to the reference potential. The circuit arrangement operates on the basic principle that a first capacitor is charged, by means of a voltage rise on a coil after current has been removed from it, to a voltage which is positive with respect to the fixed reference-earth potential. During the on-phase of a transistor, the first capacitor charges a second capacitor to a voltage which is negative with respect to the fixed reference-earth potential and can be picked off from the outside. An electrical resistor is connected between the circuit output connection and the control line of the transistor.

A tandem master cylinder for hydraulic brake systems of automotive vehicles. The push-rod piston (29) and the floating piston (34) both are provided with a central valve. The central valve of the push-rod piston is coupled to the floating piston. The length of the bore (28) of the central valve in the push-rod piston (29) is dimensioned to allow the valve closure member (27) of the central valve in the push-rod piston to travel a distance within the bore of the central valve at least equal to the stroke of the floating piston (34).
