Title: Control method for the engagement of a torque converter clutch
Inventor: NITZ LARRY THEODORE
IPC: F16H59/46
Filed: 1992-09-16
Granted: 1997-02-18
Abstract: An improved torque converter clutch (TCC) engagement control method utilizing a combination of pressure control and flow control methodologies to ensure consistently smooth and timely TCC engagement. The engagement is initiated with a pressure control methodology in which the duty cycle of a PWM actuator is selected to produce a desired pressure differential across the TCC clutch plate.  However, if the flow conditions are such that the pressure control methodology fails to promptly initiate engagement of the TCC, as detected in relation to the speed difference across the torque converter, a flow control methodology is substituted for the pressure control to initiate clutch engagement.  In this case, the duty cycle of the actuator is adjusted to a value which provides full or near-full fluid flow.  This control is maintained for a predetermined period, or until the speed difference across the torque converter indicates initiation of TCC engagement.  At such point, the pressure control methodology is resumed to complete the TCC engagement.

Title: Pseudorandom noise ranging receiver which compensates for multipath distortion by dynamically adjusting the time delay spacing between early and late correlators
Inventor: FENTON PATRICK C
IPC: H04B1/709
Filed: 1993-01-22
Granted: 2004-04-06
Abstract: A receiver for pseudorandom noise (PRN) encoded signals consisting of a sampling circuit, multiple carrier and code synchronizing circuits, and multiple digital correlators. The sampling circuit provides digital samples of a received composite signal to each of the several receiver channel circuits. The synchronizing circuits are preferably non-coherent, in the sense that they track any phase shifts in the received signal and adjust the frequency and phase of a locally generated carrier reference signal accordingly, even in the presence of Doppler or ionospheric distortion. The correlators in each channel form a delay lock loop (DLL) which correlates the digital samples of the composite signal with locally generated PRN code values to produce a plurality of (early, late), or (punctual, early-minus-late) correlation signals. Thus, during an initial acquisition mode, the delay spacing is relatively wide, on the order of approximately one PRD1 code chip time. However, once PRN code synchronism has been achieved, the code delay spacing is narrowed, to a fraction of a PRN code chip time. There are several advantages to this arrangement, especially in environments wherein multipath distortion in the received composite signal is of the same order of magnitude as a PRN code chip time.

Abstract: Genes encoding class II EPSPS enzymes are disclosed. The genes are useful in producing transformed bacteria and plants which are tolerant to glyphosate herbicide. Class II EPSPS genes share very little homology with known, Class I EPSPS genes, and do not hybridize to probes from Class I EPSPS's. The Class II EPSPS  enzymes are characterized by being more kinetically efficient than Class I EPSPS's in the presence of glyphosate. Plants transformed with Class II EPSPS genes are also disclosed as well as a method for selectively controlling weeds in a planted crop field.

Granted: 1999-05-18
Abstract: A plurality of frames associated with sequences of video source material representing a series of scene changes are digitized.  A computerized process  analyzes the digitized information and identifies one or more frames of the source material associated with and representative of each such scene change and/or sequence. The representative frames are displayed. A selected frame from the display will thereby cause automatic selection and association of a sequence of frames comprising a corresponding video sequence from which the  frame  was  selected  for  subsequent  playback.  In  a preferred embodiment,  the  entirety of  the  representative frames or a subset thereof are specified and ordered. The order  of  the  corresponding  frames  of  video  segments  or scenes corresponding  to  each  such  selected  and  ordered representative frame are thereby automatically also ordered. Simplified video  editing  is  accomplished by manipulating these  representative  frames,   each  associated  with  a different scene or video sequence.

Title: Correlation detector and communication apparatus
Inventor: DOHI TOMOHIRO
IPC: H04L7/00
Filed: 1994-10-13
Granted: 1999-09-28
Abstract: A correlation detector for CDMA communication receivers, which can establish synchronization at a high speed, can extract mutually correlated components, and can perform highly accurate tracking. The received signal (21) is fed to a matched filter (43) when the initial synchronization is established. When a synchronization judging circuit (45) judges that the filter (43) detects synchronization, the switching circuit (42) feeds the signal (21) to multipliers (47, 48), and resets a VCCG (29) and a spread-spectrum code replica generator (30). After the synchronization is established, the spread-spectrum signal is detected quasi-synchronously, the received signal quasi-synchronously detected is multiplied by replical codes having advanced and lagged phases, and correlation detection signals are extracted from the multiplication results. The square components are generated, added together in opposite phases, and averaged in the time direction. The received spread-spectrum signal is multiplied by the codes whose phases are synchronous, and the results are integrated over chips. The signal, after the averaging processing, is reversely modulated by use of the identification signal of the received data obtained by compensation for the phase error of the received signal in order to generate a phase error signal. The replica code generator is driven by a clock the phase of which is controlled by the phase error signal.
