Title: Voltage regulated DC supply with intermediate transistor chopper - which is modulated to reduce frequency disturbance to connected load
Inventor: MICHAELIS ROLF DIPL ING
IPC: H02M3/335
Filed: 1980-07-25
Abstract: The power supply finds application in telecommunication equipment. The object is to reduce interference from the chopper stage especially when the power supply is feeding frequency sensitive or selective equipment. The supply alternating voltage (1) is rectified and smoothed (2) and applied to the primary winding (5) of a transistor (4) controlled chopper (3). The chopper output is rectified (7) and applied to the load (9), for example an active filter. The rectified voltage is fed back as the control signal (15) to adjust the mark-space ratio of an impulse generator (13) in order to keep the chopper output constant. A modulating generator (16) slowly changes the impulse frequency in a sinusoidal manner. This sinusoidal modulation spreads the disturbing frequencies due to the chopper action over a wider band and, importantly, also reduces the energy content of each frequency. The disturbing effect on the load is thus greatly reduced from the value which would exist without modulation.

Patent DE-3035565-A1 (DE)
Inventor: NEY HERMANN DIPL PHYS
IPC: G10L15/00
Filed: 1980-09-20
Abstract: The degree of mis-match which would be obtained between a test and a reference signal, for example speech signals, should their time-axes be subjected to that relative shift and/or distortion which is required to minimize the degree of mismatch is carried out by sampling the two signals at regular intervals and storing these samples in memories. All the samples of one signal are then read out in succession from one memory; each successive sample of the other signal is read out from the other memory, and the difference between each pair of samples is formed in a subtractor. Each difference value from the subtractor is added to the smallest of three quantities, X, Y and Z and the result stored in a register to form the new quantity X. This new quantity X is also stored in a further memory cyclically addressed in tandem with the memory 12. The quantity Z is the previous content of the location of memory into which the new quantity X is written, and the quantity Y is the previous value of the quantity Z, obtained by shifting the previous value of the quantity Z in a two-stage shift register. Thus the quantities X, Y and Z correspond to the present sample of the other signal and the immediately preceding sample of the one signal, the immediately preceding sample of both signals, and the present sample of the one signal and the immediately preceding sample of the other signal respectively. The result is that each successive value of the quantity X is the optimum cumulative distance value between the two signals for the corresponding pair of samples should these be assigned to each other when matching the two signals to each other. The process is continued until all the sampled value have been read and paired, at which point the value of the quantity X is a measure of the above-defined degree of mis-match.

Abstract: Viele Sportgeräte, insbesondere für den Wassersport, verlangen einerseits einen sicheren Stand des Benutzers unter allen entgegenwirkenden Einflüssen (heftige Bewegung, feuchte Oberflächen, Wasserschwall) andererseits eine freie Standortwahl (Gewichtstrimm, Lenkung). Herkömmliche Hilfs-mittel (rauhe Oberflächen, Fußschlaufen, profilierte Schuhsohlen) genügen diesen Anforderungen nur unvollkommen und können Verletzungen (Abschurfungen, Verrenkungen) verursachen. Erfindungsgemäß wird die Aufgabe durch Anbringung von Klettband in geeigneter Qualität und Paarung - auf den Standflächen des Sportgerätes und auf den Schuhsohlen des Benutzers - gelöst. Vorzugsweise wird auf dem Sportgerät das weichere Flausch- oder Schlingenband angebracht und auf den Sohlen das Haft- oder Hakenband. Diese zueinander komplementaren Lagen verhaken sich beim Auftreten, wodurch eine recht feste Verbindung entsteht, die sich aber mit mäßigem Kraftaufwand wieder lösen läßt. Die Anordnung eignet sich besonders zur Verwendung auf Surfbrettern (Brandungs- und Windsurfern), Booten mit Trapezeinrichtung, Wasserskiern usw.                             (3111 227)
