Title: Feedback control for reduction of cogging torque in controled current ac motor drives and method
IPC: H02P27/06
Filed: 1978-07-18
Granted: 1982-07-21
Abstract: A decogging feedback control for current source inverter motor drives uses a change of instantaneous torque feedback signal with no dc component that is a function of only the instantaneous pulsating component of measured torque. The change of torque signal modulates the voltage applied to the dc link and therefore the dc link current to materially reduce the detrimental cogging torque pulsations and stabilize the motor, and can be switched out at a low frequency above which it is not needed so that the motor can respond properly to rapid variations in torque.

Title: Data card verification system
Inventor: VANSTONE SCOTT A
IPC: H04L9/32
Filed: 1997-02-03
Granted: 2000-10-04
Abstract: A method of verifying a pair of correspondents in electronic transaction, the correspondents each including first and second signature schemes and wherein the first signature scheme is computationally more difficult in signing than verifying and the second signature scheme is computationally more difficult in verifying than signing. The method comprises the step of the first correspondent signing information according to the first signature scheme and transmitting the first signature to the second correspondent, the second correspondent verifying the first signature received from the first correspondent, wherein the verification is performed according to the first signature scheme. The second correspondent then signs information according to the second signature scheme and transmits the second signature to the first correspondent, the first correspondent verifies the second signature received from the second correspondent, wherein the verification is performed according to the second signature algorithm; the transaction is rejected if either verification fails. The method thereby allows one of the correspondents to participate with relatively little computing power while maintaining security of the transaction.

Inventor: DINI GENNARO
IPC: B01D/
Filed: 1986-03-14
Granted: 1988-02-24
Abstract: An audio signal processor treats a digitally encoded signal. Units (3, 12) sample the encoded signal and units (8, 13) calculate from the sampled values a correlation function relevant to a particular time frame. The function value serves to control an adaptive echo cancellation algorithm. The sampled signal portions are truncated (2, 5) so that only the arithmetic sign bit of each signal portion contributes to the function calculation. An incoming signal sample is initially treated in an extraction block arranged to determine the arithmetic sign relevant to that signal, the resulting sign bits being fed in sequence to a shift register arranged to store a predetermined number of sign bits. Outputs are provided from selected locations in the register in accordance with a control logic select circuit.

Granted: 1987-08-26
Abstract: A diaphragm responsive to fluid pressure operates a snap-action switch connecting the motor (76) to a source of current, via moving contacts (20) and stationary contacts (36-39). The motor is protected against water system failures by control components located in a front chamber (110), including a relay (150), a current detector (152) and control logic circuit (154). Red and yellow LEDs (156,158) with flashing and steady indications give warnings of fault conditions such as no-load, r rapid cycling, low or high voltage, overload or extended run. A desired operating condition of the motor can be entered into nonvolatile memory by means of a front-panel pushbutton (160). The logic circuit (154) interrupts or prevents energisation of the motor when any variation in its operating conditions exceeds a preprogrammed limit.

Title: Power-driven screw and nut backlash corrector
Inventor: KALMAN ROZSA
IPC: B41J/
Filed: 1982-10-01
Granted: 1986-12-03
Abstract: The nut mounted on e.g. a printer carriage is driven by a screw rotated by a motor. The position of the print head is sensed by an incremental code disc and photoelectric device producing two pulse trains in quadrature. A processor modifies these for transfer to a decoder of position and direction of motion, signalling to an up/down counter which operates a motor controller. A backlash measurement device stores the measured value with a resolution of one-quarter of the pulse train period for transfer to the processor. The backlash is compensated in steps by relative displacement of the two pulse trains, which are combined in four different ways and in a succession selected to correspond with the stored backlash value.
