Abstract: An installation/removal device is used to install and remove a fuel injector in/from a receiving bore hole of an internal-combustion-engine cylinder head. The installation/removal device includes a sheathing member having a tubular section and a contacting section, which acts on and/or contacts the fuel injector by a contact surface that extends radially inwardly. The contacting section, which can be formed by at least two elastic, contacting subsections separated from each other by cut-outs, is adjustable between an engaged position; in which a frictional connection to the fuel injector can be established, and a released position in which the installation/removal device can be removed from the fuel injector.

Abstract: An automotive radar system having an oscillator is described, the oscillator generating a high-frequency signal only in intervals as a function of a control signal during operation of the radar system. The oscillator includes a microwave diode, in particular a Gunn diode or an Impatt diode, accommodated inside a casing-like body. At least one of the following components, an ohmic resistor, a transistor or an IC is arranged so that it is thermally connected to the casing-like body or to an element thermally connected to the latter, the component having at least one additional function in the circuit configuration of the radar system other than generating heat. This guarantees that the oscillator will oscillate reliably even at very low temperatures and in particular in chopping operation.

Abstract: An engagement relay for starters of internal combustion engines as proposed, with which a starter pinion is first shifted into the gear ring of the engine and then the starter motor is turned on. For gently rotating the starter pinion into the gear ring by means of the starter motor, it is proposed that the switch of the engagement relay be embodied as a switchover contact 54, which in the position of repose switches the starter motor via a resistor 39 and in the working position switches it directly to the electrical supply (plus 30), and then the resistor (3) is turned off.

The exciter machine is located to the side of the generator and has substantially smaller dimensions than the latter. At claws (28, 29) of the stator (25) which face the armature (32) of the exciter machine, permanent magnets (39) are located in the leakage flux area between the claws. Unwanted leakage fields are contained in this way.

The piston pump has a piston which is received in a bush that is inserted into a cylinder bore of a pump housing that is closed in pressure-tight fashion by a closure part.

As a result, a preassembled unit that can be manipulated easily before insertion into the pump housing is obtained in a simple way.

Abstract: 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.

In fabricating the local reinforcement of the microfeature, at least one further organic layer, formed as a mask, is deposited, which is likewise removed following pattern delineation of the metallic layer.

Abstract: A method via which the range of vision in a vehicle's field of view can be determined precisely, so that with the help of range-of-vision information the driver can be advised to modify his driving style. The contrast of an object detected by a radar or lidar sensor is measured by a monocular video sensor, and the range of vision is determined from the measured values supplied by the radar or lidar sensor and by the monocular video sensor. Alternatively, the distance to and contrast of at least one object can be measured by a binocular video sensor, the range of vision then being determined from the measured contrast and distance values.

Abstract: An apparatus for kinesthetic signaling to a driver of a motor vehicle is described. The apparatus signaling the driver if, in the context of a system for controlling vehicle speed, a deliberate shutdown or one occasioned by a malfunction is imminent or exists; or if, in the context of a system for controlling vehicle speed, a preset maximum deceleration value is not sufficient to prevent a collision between the motor vehicle and a preceding vehicle or an obstacle. The apparatus includes a device that modulates a braking setpoint, or a variable derived from it, in such a way that the motor vehicle experiences a temporally fluctuating deceleration that is perceptible by the driver.

Abstract: An electronically commutated motor includes a stator carrying a plurality of winding strands and a rotor in which the individual winding strands are controlled via power amplifiers in staggered periods of time, the periods being subdivided into control time and idle time. To reduce the power loss in the power amplifiers and to increase the efficiency in the range of high currents, that the control times are subdivided into an initial time segment and a final time segment. At low motor currents pulsing occurs only in the initial or final time segments in pulse width modulation, while at high currents complete switching through takes place in the initial time segments and additionally in the final time segment for a more or less long period of time or in the final time segments and additionally in the initial time segments for a more or less long period of time.

Abstract: A drum-in-hat park brake assembly having a first brake shoe retained on a backing plate by a first pin and a second brake shoe retained by a second pin. The first and second pins permit the first and second brake shoes to be moved in a radial plane and to rotate about an axis of an opening in the backing plate. The first and second brake shoes each have a first engagement end which is aligned on the backing plate by an anchor post and a second engagement end which is selectively spaced apart by an adjuster mechanism. A spring arrangement urges the first and second brake shoes toward the anchor post and into engagement with the adjuster mechanism. An actuator assembly is connected to the first engagement end of the first and second brake shoes and upon receiving an input force moves first and second friction pads associated with the first and second brake shoes into radial engagement with a drum.
