Abstract: The invention relates to a driver circuit for a D.C. motor without a commutator, especially to drive a ventilator. Within each commutation phase, which is determined by a rotor position sensor circuit (2), a control pulse is supplied whose duration and/or amplitude is varied to control the power supplied to the motor. Provided in order to generate the control pulses is a triangular wave form generator (21) whose period duration corresponds approximately to one commutation phase. The time of at least one edge of the control pulses for the output stages (60, 70) is defined by comparing the triangular wave form signal with a reference signal. <IMAGE>

Abstract: A method of forming an oxide film and a method of manufacturing an electronic device utilizing the oxide film is disclosed. A silicon oxide film is formed on a substrate by sputtering. Therefore, the film formation is carried out at a low temperature. The sputtering atmosphere comprises an oxidizing gas and an inert gas such as argon. In order to prevent fixed electric charges from being generated in the film and to obtain an oxide film of good properties, the proportion of argon is adjusted to 20% or less. Alternatively, a gas including halogen elements such as fluorine is added to the above sputtering atmosphere at a proportion less than 20%. Hereupon, alkali ions and dangling bonds of silicon in the oxide film are neutralized by the halogen elements, whereby a fine oxide film is obtained.

Abstract: An adaptive flash rejection filter for a color flow imaging apparatus uses a flash strength identifier to make an initial determination of flash content. The identifier assigns a flash strength to each signal portion of a scan line according to a velocity component and a magnitude component of that signal portion. The number of flash strengths in a line which fall into a designated flash range are accumulated to arrive at an approximate measure of flash content. A filter arrangement uses the accumulated flash content to determine a proper flash rejection level for a line. An entire line of flash strengths and velocity measurements are stored in a line memory, which serves to delay those signals while the proper flash rejection level is being determined. The filter arrangement then receives the flash strengths and the velocity components, and inhibits an output of a velocity component if its corresponding flash strength exceeds the assigned flash rejection level. This serves to reject velocity components containing flash and prevent their processing by the color flow display circuitry.

Abstract: A method and system are disclosed for improved edge detection on tapes. By use of a nominal tape having a 100% output, a write head writes with a given write current onto the nominal tape and the output level is read with a read head during a calibration procedure in order to determine a reference level for the 100% nominal tape. Thereafter, when an actual tape is being used, by use of the same write current, a signal is written on the actual tape and is subsequently read to create a read output. That read output is compared to the reference level output derived during the calibration to create a correction factor. The correction factor is then employed to correct a trigger point utilized during a subsequent tape edge determination.

Abstract: Forged signatures are discriminated from authentic signatures in a verification process which relies on dynamic signature properties. In an initialization phase (010) a reference set of authentic signatures is obtained. A set of dynamical properties (140.1, 140.2, 140.3) of the reference signatures is computed numerically. The most characteristic subset of such properties is selected and statistically analyzed to obtain a set of parameters for signature verification. An entrant signature is subsequently accepted or rejected (160, 170) based on its conformity to the parameters. An accepted signature is optionally passed along to a higher-level verification process. When a signature is accepted by the highest-level verification process, responsive means (050) are activated, resulting in the entrant's access to a system.
