The invented apparatus includes at least one feeder and a base unit for successively advancing one or more tapes containing electronic components so that such components can be extracted by a pick-up device for installation in circuit boards, for example. The feeder can include a body, a sprocket, a slider, and a one-way drive member. The body defines a guide through which a tape extends, and its sprocket is rotatably mounted in the body so that its teeth engage with and advance the tape if the sprocket is rotated. The drive member is mounted to the slider, and the slider is mounted to reciprocate in the body. The slider moves the drive member into contact with sprocket to rotate the sprocket by an amount sufficient to advance the tape by one interval to expose the next electronic component for extraction from the feeder. The apparatus' base unit can include at least one sensor, a controller, and at least one solenoid unit. The sensor generates a signal to indicate the release of pressure on the feeder as a pick-up device moves away from the feeder to extract an electronic component from the tape. After a predetermined time delay sufficient to permit the pick-up device to move clear of the feeder, the controller generates controls signals supplied to at least one solenoid unit to reciprocate the feeder's slider to advance the tape. The feeder can also include a mechanism that compacts the cover tape removed from a carrier tape for electronic components, into a string-like configuration for ready disposal, and a mechanism which prevents an electronic component from escaping the feeder before extraction by the pick-up device. The invention also includes related feeders and methods.

The invention is directed to an automatic standstill brake for motor vehicles equipped with an automatic transmission wherein a braking pressure is generated at the wheel-brake cylinders via devices operating on the brake circuit of the motor vehicle. The automatic standstill brake prevents a rolling of the motor vehicle when at standstill. The standstill brake operates when the motor vehicle has come to standstill and the driver has released the brake pedal so that it goes into its rest position. The standstill brake includes a computer which provides an output for a signal transmitter which supplies an actuating signal which, in turn, is applied to the devices operating on the brake circuit thereby causing the standstill brake to become engaged or disengaged. The computer forms the output thereof from the input signal of a sensor for the actual speed of the motor vehicle, an input signal of a sensor for the actuation of the brake pedal and an input signal of a sensor for the actuation of the accelerator pedal.

A method and an apparatus based thereon are described for the automatic recognition of whether, in a traffic situation or in a traffic environment, vehicles are driving on the right or on the left. Said method is used in a motor vehicle as part of adaptive speed control. The prevailing direction of traffic flow is determined on the basis of other vehicles, which are traveling toward the cited vehicle. For this purpose, a frequency distribution is created as a function of a lateral, preferably directional distance y; a center of gravity S of this frequency is determined; and then it is determined on what side of the controlled vehicle this center of gravity S is located.
