Patent EP-0490679-A2 (EP)
Inventor: COKER THOMAS ALLYN
IPC: G11C7/22
Filed: 1991-12-12
Abstract: A read/write memory having timed-out control of certain of its peripheral circuitry is disclosed. The control circuit for controlling the time at which time-out is to occur includes two delay stages of different lengths. The shorter delay stage is used to define the time-out in a read operation, and the longer delay stage is used to define the time-out in a write operation, since a read operation can generally be accomplished sooner than a write operation. Enabling of the periphery is controlled by an address transition detection circuit, and by a data transition detection circuit. The circuit includes a short path by which enabling of the periphery is performed responsive to a data transition in the absence of an address transition, in order to perform a late write operation.

Abstract: In order to increase the measurement accuracy when determining the mass flow rate of a conveyor material, in particular a multiphase flow composed of a bulk material and a gas, using the Coriolis principle, it is proposed to measure the mass flow rate (M3) of the conveyor fluid, in particular conveyor air, before entry into the Coriolis measurement wheel (4), and then to form the difference (M2) between the total mass flow rate (M1), determined at the measurement wheel (4) by the drive torque, of the conveyor material together with the conveyor fluid and the separately established mass flow rate (M3) of the conveyor fluid. In a preferred embodiment, the conveyor fluid measuring device is also constructed as a Coriolis measurement wheel. The proposed method and the corresponding device enable account to be taken of the conveyor fluid mass flow rate when determining the mass flow rate of the conveyor material.

Abstract: A plurality of portable tokens are issued e.g. for authenticating payment instructions within an electronic banking network. Each token requires entry of a respective password in order to operate and becomes locked if a number of incorrect password entries are made. Each token also stores a respective cryptographic key and a random number generator. In order to unlock a locked token it outputs a random number and also encrypts that number under its respective key but does not output the result of the encryption. The random number is transmitted by the user to a central authority which stores the keys for all tokens. The authority encrypts that number under the respective key and returns the result of the encryption to the user of the token. The returned number is entered into the token and if it agrees with the result of the internal encryption the token is unlocked.

Abstract: Das Verfahren dient zur Ortung von Kabelfehlern, insbesondere zur Ortung nichtfestbrennbarer Kabelfehler im Bereich von verzweigten Kabeln. Es wird die Impulsreflexionsmethode angewendet und ein Kondensator geladen, der anschließend über eine Funkenstrecke durch Funkenüberschlag an einer Fehlerstelle des Kabels entladen wird. Parallel zu einem Hauptkondensator in einem Stoßwellengenerator wird ein zweiter Impulskondensator über einen Kurzschlußschalter auf das Kabel entladen. Die entstehende Reflexionswelle wird über eine Auskoppelung einem ersten Kanal des Digitalspeichers zugeführt. Nach Öffnen des Kurzschlußschalters werden der Hauptkondensator im Stoßwellengenerator und der zweite Impulskondensator erneut aufgeladen und anschließend wiederum durch Schließen des Hauptschalters auf das fehlerhafte Kabel entladen. Die Entladung des Impulskondensators erfolgt über eine plasmagetriggerte Funkenstrecke. Die Funkenstrecke wird aus der Ladung des Stoßwellengenerators getriggert. Durch eine Zeitverzögerung bei der Plasmabildung erreicht ein Entladeimpuls des Impulskondensators die Fehlerstelle im Kabel nach bereits erfolgter Zündung. Die dabei entstehende zündverzögerungsfreie Reflexionswelle wird über die Auskoppelung einem zweiten Kanal des Digitalspeichers zugeführt. Durch eine Auswertung auftretender Abweichungen beider Aufzeichnungen wird der Fehlerort ermittelt. <IMAGE>

Abstract: A self-tuning tracking controller for permanent-magnet synchronous motors is disclosed, providing for velocity or position trajectory tracking even when both the electrical and mechanical parameters of the motor, amplifier, and load are initially unknown. A time-scale simplification of a full-order mathematical model of the motor leads to a discrete-time design model that is reduced-order and that evolves in a mechanical time-scale which is substantially slower than the electrical time-scale, permitting implementation of the self-tuning tracking controller with a lower sampling frequency (and at a lower cost) than is typically expected. A piecewise-linear parameterization of the motor torque-angle characteristic functions allows for identification of higher-order harmonics with a degree of accuracy which is selectable by the user, without requiring more computation than traditional single-term sinusoidal descriptions. Excellent performance is achieved, even with very poor initial motor parameter knowledge.

Abstract: This invention relates to an inking member made from a single, foraminous material. The foraminous material, such as polyurethane, is placed into a press. The top platen of the press is raised to a temperature of 380 to 450° F and the material is subjected to a pressure of 8,618kg/force on a 165mm ram load for a period approximately of 3.5 minutes. What results is an inking member having small pores in the area adjacent to the heated platen and larger pores in those portions of the pad that are distant from the heated platen. This yields a foraminous, member that has utility as an inking member with the small pore portion acting as an ink metering layer and the large pore portion acting as an ink reservoir layer.

Abstract: A disk drive having a passive slider exhibiting two fly heights, one for recording and reading operations and a second for idling, is disclosed. The disk drive has a magnetic recording surface set for rotation in a direction. A transducer carrier is radially positionable relative to the magnetic recording surface and can be moved between recording portions and idling portions of the annular surface. In the idling zone the surface includes a plurality of shallow depressions (84,86) disposed in an annular zone. The depressions are generally trench like. The orientation of the depressions depends on the type carrier for the transducer. If oriented transversely to the direction of rotation of the magnetic recording surface, they will boost pressure under the carrier increasing or introducing spacing between the body and the carrier. Where the carrier has an air bearing surface including regions creating zones of relatively negative pressure, the depressions are grooves paralleling the direction of rotation of the disk. The grooves diminish the effectiveness of the zones of negative pressure to increase carrier fly height.
