Abstract: A synthesizer guitar controller pickup and method for generating control signals for a synthesizer. The control signals are NOTE, GATE, and VELOCITY. NOTE corresponds to the pitch, GATE corresponds to when the sound is initiated and stopped and VELOCITY is a signal which is proportional to the force applied to the guitar string. A DC sensor, such as a photo detector or Hall Effect transducer, is employed to detect these signals. The DC sensor measures how far the string deviates from its rest position, this value is the VELOCITY signal. The flyback from the peak deflection initiates the GATE signal to turn on the sound. When the string stops vibrating, the GATE, and thus the sound, is turned off.
Abstract: The measuring-value sensor according to the present invention for the measurement of extensions, for example in concrete or shotcrete, consists of a support member, having an extension stiffness value that is lower than the extension stiffness value of the material diameter displaced by the sensor. Transverse elements are located at either end of the support member, which induce the impact. By combining sufficiently large transverse elements that have a relatively high flexural strength and a support member that has the above-mentioned very low extension stiffness value it is made sure that extensions in the concrete are forced completely and without obstruction upon the support member by means of the transverse elements, so that when measuring the extension of the support member, the extension of the concrete is measured directly and without any distortion. The support member is suitably a hollow profile of aluminum or a plastic material, into which an additional profile, e.g.

Abstract: The invention relates to a tangential-belt drive for a plurality of work units of the same kind, arranged at least in one row next to each other, of a machine for the production of twisted or twined yarns. The work units are divided into sections with at least approximately the same number of work units, each driven with an endless tangential belt. At least one electromotor is assigned to each section for driving the thereto pertaining tangential belt and guiding means for the tangential belt.In order to reduce the energy losses of such a tangential-belt drive, the width and thickness of the tangential belt used is considerably reduced, particularly to a width between 7 and 14 mm and a thickness between 2 and 2.7 mm. Size reduction becomes possible because the number of working units in each section is selected by considering the working capacity required by this number of work units and the acceptable belt stretch factor.

Abstract: The process according to the invention controls a drying device for a vehicle wash for a vehicle, a travelling portion of the drying device being movable relative to the vehicle with the aid of a travel motor and a lift motor. The travelling portion carries a drying means and a light barrier whose light beam passes with clearance under the drying means and a device controller operating the travel and lift motors guided on a path which keeps a guaranteed clearance from the contour of the vehicle. At the beginning of the drying process the portion of the drying device in a lowered initial position in front of or behind the vehicle is moved. As a result at least the raising and lowering of that portion is controlled by a gating signal. Before beginning each drying process the sensitivity or response threshold of a gating device for the gating signal and/or a conditioning device adjusting the gating signal is adjusted automatically to a value sufficient to define the release of the light beam.
