Abstract: The ultrasonic tracking control effects that a pacemaker going ahead is automatically tracked by an automotive vehicle at a predetermined distance. To this end, a control unit (13) of the vehicle (10) is equipped with two ultrasonic units (F1,F2) comprising a transceiver device for ultrasonic signals each. The pacemaker going ahead carries a second control unit (14) with a transponder (S) responding to the signals of the ultrasonic units (F1,F2). Upon reception of an ultrasonic signal, the transponder (S) outputs a response signal which is received by the respective ultrasonic unit. The distance of the vehicle from the pacemaker and the tracking angle (.alpha.) are determined in the first control unit (13) from the signals received by the ultrasonic units (F1,F2), and traveling and steering signals are generated such that the vehicle tracks the pacemaker at a predetermined distance.

Abstract: A portable display includes a central display panel and opposite side tubular hollow end panels or columns constructed from a single sheet of substantially resilient elongated material. Each column is formed by rolling a side edge portion rearward bringing a tubular polygonal reinforcing member carried by each side edge portion into magnetically attracted sectirement with another hollow member. Hubs are inserted into the interior of the side columns to lend rigidity thereto, and two such displays or display sections can be stacked one relative to the other to transform a table-top display to a floor display. In this stacked configuration magnetically attractable securing elements hold the lower edge portion of an upper display section intimately relative to an upper edge portion of a lower display section.

Abstract: A method and apparatus that allows a bed system to recall bed functions is accomplished by providing a bed controller with additional memory and processing steps. The additional memory is used to store current bed function data, desired bed function data, and recall bed function instructions. The additional processing, when executing the recall bed function instructions, compares the current bed function data with the desired bed function data. When the data does not match, the additional processing generates a function adjust signal which causes the bed to readjust itself to the desired function.

Abstract: A cooktop, hob top or the like includes a cooktop, hob top panel having a peripheral edge portion, a frame bordering the same and a substantially one-piece homogeneous injection molded polymeric/copolymeric encapsulation securing the peripheral edge portion of the panel to the frame. The encapsulation includes integral fasteners adapted to be inserted into openings of a horizontal flange of a range, countertop or the like.

Abstract: This invention is designed to reduce the number of parts in the circuits of a constant-voltage automatic charging strobe circuit, thus reducing the cost. In addition, it allows a user to decide when to use the strobe flash. In a oscillation charge/discharge circuit, an oscillation startup switch is installed between a battery and a transistor through the primary coil of a step-up transformer. When the switch is closed, the direct current input to the transistor is suppressed, and an abnormal input current control resister may have a low resistance value. A trigger flash circuit comprises a circuit that both controls the constant-voltage flash of a neon lamp NE and controls the oscillation stop of the transistor. A recharge circuit comprises a circuit that uses the resistor in the primary coil of the step-up transformer and a capacitor that takes out pulse fluctuations when the xenon lamp Xe is flashed.

Abstract: A vehicle steering angle control device which accurately guides a vehicle along a predetermined drive course by accurately controlling a steering angle of the vehicle based on a degree of curvature of a curved course on which the vehicle is currently running and a current speed of the vehicle in which the degree of curvature of the curved course on which the vehicle is currently running is determined by calculating a degree of deviation of the vehicle relative to a vehicle advancing direction corresponding to current vehicle advancing direction data or an integration of the degree of deviation and a current speed of the vehicle is detected; a steering angle suitable for the degree of curvature of the curved course and the current speed of the vehicle is found and the steering angle of the vehicle is controlled to realize the suitable steering angle, whereby the vehicle is guided along the predetermined driving course.

Abstract: The main object of the invention is to obtain knitwork the density of which is not influenced by the tension of the previously formed loops (15). In the particular case of terry cloth the terries are hence particularly uniform and stable.This is achieved by operationally interposing the terry sinker (2) between two stitch sinkers (3, 21).The method for producing terry knitwork is as follows:the first yarn (12) passes under the stitch hooks (7) while resting on the knocking-over surfaces (8) of the stitch sinkers (3, 21), and then over the terry hook (4) while resting on the terry surface (5) of the terry sinker (2);the second yarn (13) follows the first yarn (12), but instead of passing over the terry hook (4) passes along the working surface (6) of the terry sinker (2).The method for producing wide-mesh knitwork comprises for both yarns (12, 13) a path identical to that of the first yarn (12) of the terry knitwork production method.
