Patent CA-2099156-A1 (CA)
Inventor: FALCK PETER L
IPC: F16H59/42
Filed: 1993-06-25
Abstract: A control system for a vehicle powershift transmission includes a set of electrical connectors which, in a normal mode, permit electrical power to be transmitted to microprocessor-controlled valve drivers for the transmission clutch control valves.  These connectors may be swapped, in a limp-home mode, to permit power to be transmitted directly to the transmission clutch control valves.  In both modes, a start-in-gear protection circuit including a pair of relays and switches coupled to the shift lever prevents the vehicle from being started up with a gear engaged.  In the limp-home mode, a limp-home relay and a clutch disengaged switch prevents gear engagement until the operator has depressed and then released the clutch pedal, and the clutch pedal may be operated to modulate and control gear engagement.

Title: Power Conversion Control Apparatus
Inventor: NAKAMURA NAOMI
IPC: H02M7/162
Filed: 1993-08-13
Abstract: A power conversion system has a control circuit constituted by a dual system. The control circuit of each system is equipped with a current control circuit.  The current control circuit has a selection circuit that, after determining the magnitude of the output of an integrating amplifier of its own system and the output of an integrating amplifier of the other system, selects one of the outputs of the two integrating amplifiers.  The selection  circuit applies  a  signal  responsive to a difference between the output of the integrating amplifier of its own system and the output of the selection circuit of its own system as correction signal to the input of the integrating amplifier of its own system.    Accordingly, when the power conversion system is utilizes a dual control system, even when the current control circuit includes an integration algorithm, control can be performed by the two systems without saturation due to the integration algorithm.

Title: Apparatus for implementing interrupts in pipelined processors
Inventor: JEFFS PAUL V
IPC: G06F9/48
Filed: 1993-09-09
Abstract: In a computing system of the type which executes instructions having the form A op B - B, a floating point register includes a plurality of addressable storage elements for storing operand data. A first address receiving circuit receives the B operand address from a first instruction, and a second address receiving circuit receives the A operand address from the first instruction. The A and B operand addresses are each used for addressing one of the plurality of floating point register storage elements. An instruction executing circuit performs a function designated by the first instruction on the operand data output from the floating point register and generates result data. The instruction executing circuit includes an exception circuit for generating exception data indicating whether an exception occurred when the function was performed. A shift register has a plurality of storage elements for storing address and control information. A first address storing circuit stares the B operand address in a selected one of the plurality of shift register storage elements, and a shift register output circuit outputs the stored first instruction B operand address at approximately the time the result data corresponding to the first instruction is generated by the instruction executing circuit. A floating point register storage control circuit stores the result data corresponding to the first instruction in the floating point register storage element addressed by the stored first instruction B operand address as long as no exception occurred when the function was performed. However, the floating point register storage control circuit inhibits the storage of the result data in the floating point register when an exception does occur so that the old B operand value is not destroyed by a probably erroneous value.      An operand queue includes a plurality of storage elements for storing A operand data output by the floating paint register, and a trap queue includes a plurality of storage elements for storing A operand data corresponding to an instruction which generated exception data, and A trap queue data storing circuit stores the A operand data output from the operand queue into one of the trap queue storage elements whenever an exception is detected. The instructions which were executing when the first exception is detected are allowed to complete.

Title: Non-contact photothermal method for measuring thermal diffusivity and electronic defect properties of solids
Inventor: MANDELIS ANDREAS
IPC: G01N25/18
Filed: 1994-06-22
Abstract: There is provided a method of measuring thermal diffusivity of solids and electronic lifetimes and defect properties of semiconductors useful for in-situ, non-destructive monitoring of engineered materials and electronic substrates.  The method, termed photothermal rate window method, involves irradiating a sample with a repetitive square laser pulse of duration Tp and period T0 and monitoring the temperature profile by measuring the photothermal signal emitted from the sample. The period T0 of the repetitive heating pulse is maintained constant and the pulse duration Tp is varied in the range between 0 and T0 with the temperature measured at each value of Tp. The method of measuring semiconductor recombination lifetimes involves irradiating a sample and scanning one of either the period T0 and the pulse duration Tp of the repetitive laser pulse with the other held constant. The photothermal signal emitted from the surface is measured.  Defect energy states in semiconductors are measured by irradiating the sample with a repetitive laser pulse of duration Tp and period T0 (both fixed) and monitoring the photothermal signal as the sample temperature is scanned. Defect levels are correlated with extremum in the profile. The photothermal signal in all the foregoing methods is input into a lock-in amplifier which measures the fundamental Fourier component of the signal. The output of the lock-in amplifier is fitted to a theoretical model of the photothermal response of a repetitively irradiated sample to obtain the thermal diffusivity, or the recombination lifetime.

Abstract: An apparatus of the present invention can achieve an improved image quality, irrespective of either a still image or a motion image to be obtained, when a scanning line number is converted.  To this end, an interlaced scanning signal is input to a field delay circuit and to a vertical highpass filter, the output of the field delay circuit is input to a field delay circuit and to a vertical lowpass filter, and the output of the field delay circuit is input to a vertical highpass filter.  The outputs of the vertical highpass filters are added together at an adder.  The output of the adder is added by an adder to the output of the vertical lowpass filter to create an interpolation signal.  The interpolation signal and direct-type signal, being time-compressed, is coupled to a switch where they are alternately selected.  In this way, it is possible to create progressive scanning signals.
