Abstract: In the method for locating subterranean pipes, the pipe or the liquid or gaseous medium (14) contained therein is excited mechanically in a pulsed fashion by a vibration generator (22). The pulse propagates on the pipe (14) and in so doing generates in the ground solid-borne sound waves which are transmitted through the ground and reach the surface of the earth (12). The course of the line (36') along which the solid-borne sound waves reach the surface of the earth (12) is determined with the aid of solid-borne sound transducers (24, 26, 28) which detect the solid-borne sound occurring at the surface of the earth. The course of the line (36') is used to determine the position (42) of the surface (12) which, seen in projection, is located on the pipe (14) to be located. The course of the pipe (14) is traced point by point in this way. <IMAGE>

Abstract: The invention relates to a method for determining vehicle rotation rates, by means of which disturbances due to sensor principles are to be suppressed. On the one hand, the time-dependent drift in known gyro systems is to be avoided in the navigation of driverless transport systems. On the other hand, false responses of wheel sensors with respect to the directional information of the vehicle, for example when driving through potholes, is to be avoided. Remedy is here provided by a method in accordance with which a rate of rotation signal 18 generated in a gyroscope arrangement passes through a high-pass filter 20 and a rate of rotation signal 22 generated by wheel sensors passes through a low-pass filter 24, and the two individual signals 18', 22' occurring thereafter are combined to determine the actual rate of vehicle rotation. Due to the blocking effect of the low-pass filter, the sensor-related high-frequency rate of rotation signals of the wheel sensors occurring, for example, when driving through a pothole, are eliminated and can therefore no longer have an interfering effect in the determination of the vehicle rate of rotation. Furthermore, the high-pass filter prevents low-frequency disturbances which have been caused, for example, by the drift of a gyroscope. By combining the filtered rate-of-rotation measurement signals, the position angle of a driverless vehicle can be determined in a simple and fast manner. <IMAGE>

Abstract: An apparatus for electronically modifying the appearance of an image stored in the form of digital data defining the colour content of the image comprises a store (8) for storing sets of coordinates defining positions around the edge of the image and, for each set of coordinates, storing the characteristics of an electronic painting tool including the profile of the tool. A monitor (30) displays the image. A processor (1, 15-19) compares the current position of the tool with the sets of stored coordinates and when the tool is at or in the region of a set of stored coordinates changes the tool characteristics to those previously determined for that set of coordinates.

Abstract: Digital signal recording and reproducing apparatus records digital signals in successive tracks on a record medium (T) and reproduces digital signals therefrom. A rotary head assembly (11) including two pairs of head sub-assemblies separated by 180°, with each sub-assembly comprising a pair of heads (H) displaced from each other in a direction parallel to the track pitch, is driven at a predetermined rotational speed to record digital signals selectively supplied at respectively different original transmission rates which have a predetermined ratio. The digital signals are timebase modified (7) to have substantially the same data rate even although their original transmission rates differ from each other. The record medium (T) is driven (14) during a recording mode at respectively different speeds determined by the original transmission rate of the selectively supplied digital signal, whereby the number of tracks recorded on the record medium (T) during a unit time period (TP) corresponds to the original transmission rate. The record medium (T) is driven during a reproducing mode at the same speed as was used during recording, whereby during the unit time period (TP) the rotary head assembly (11) reproduces digital signals from twice the number of tracks that had been recorded during that same time period TP.

Abstract: An integrated circuit memory is disclosed which has its memory array divided into blocks, or sub-arrays. Between each sub-array is placed a row line repeater which communicates the row line from the row decoder, or from a prior sub-array, into the next sub-array. The row line repeaters are controlled according to a portion of the column address so that, after the entire selected row has been energized, those row line repeaters which are not associated with the selected sub-array will de-energize the row line at their output. The row line repeaters each include a latch, so that the row line repeater which is associated with the selected sub-array will maintain the selected row line energized. Various embodiments of the row line repeater circuit are disclosed. Further control of the row line repeaters from a power-on reset circuit is also disclosed. A dummy row line is also disclosed, which emulates an actual row line so that the time at which the selected row has been fully energized is more closely known. The dummy row line thus can control the time at which the unselected row line repeaters de-energize their outputs.
