Abstract: METHOD OF CLUTCH-TO-CLUTCH CLOSED THROTTLE   DOWNSHIFT IN AN AUTOMATIC TRANSMISSION            ABSTRACT OF THE DISCLOSURE          In an automatic transmission, clutch-to-clutch closed throttle downshifting is controlled by filling the on-coming clutch at a maximum pressure command for a set period while commanding the off-going clutch pressure to a low value and exhausting the off-going clutch before the end of the fill period.  At the end of the fill period the on-coming pressure is set to an initial value and then ramped up until turbine speed is pulled up due to off-going clutch slippage.  Then a closed-loop profile control period starts wherein the slip of the on-coming clutch is measured and controlled to a slip profile.   When synchronization of the on-coming clutch is detected, maximum pressure is commanded.  If the throttle is opened during the downshift, the algorithm reverts to a powered downshift algorithm if the off-going clutch still has pressure or to an open-loop ramp control of the on-coming clutch if the off-going clutch has been exhausted.

Title: Dual mode seat belt retractor
Inventor: ZYGUTIS JAMES L
IPC: B60R22/415
Filed: 1991-01-30
Abstract: ABSTRACT OF THE DISCLOSURE          An inertia retractor may be provided with an automatic locking mode by the addition of an assembly mounted as an attachment to sidewall of the inertia retractor.  The assembly allows the retractor to be used as an inertia retractor until the belt is pulled to a predetermined extent whereupon a belt coil sensor senses this predetermined belt extraction and operates an actuator to shift a pawl into locking engagement with the ratchet wheels and thereby into the automatic locking mode.  When the belt rewinds, the belt coil sensor deactivates the ALR mechanism by latching the pawl actuator thereby allowing an inertia member to again operate the pawl to the locking position upon a deceleration of sufficient magnitude.

Abstract: In a television receiver swivel device, a turning ring rides on an annular groove on the upper surface of a supporting base so that it is capable of swiveling relative to the supporting base.   A television receiver cabinet rides on this turning ring so that it is capable of swiveling relative to the turning ring.

A manually operated overriding means is provided to override the restriction, so that the television receiver can be swiveled manually beyond said predetermined swivel range to an angle of 180°.   A power supply limit switch may further be provided such that electric power to the television receiver is interrupted when the television receiver swivels beyond a second predetermined range (which may or may not be identical to the first-mentioned predetermined range), and is restored when it returns within the second predetermined range.

Title: Selection circuit in a space diversity reception system for a mobile receiver
Inventor: ANVARI KIOMARS
IPC: H04B7/08
Filed: 1991-11-05
Abstract: ABSTRACT       A selection system in a space diversity system of a mobile receiver combines the ultra high frequency signals after they have been frequency shifted to an intermediate frequency.  The system combines the intermediate frequency signals depending on the ratio of the magnitudes of these signals.  If the ratio of the magnitude of the received signals is equal to or greater than a preset magnitude level, for example, 5 db, a control unit selects only the received signal having the largest magnitude.  Otherwise, the control unit linearly combines both received signals.  Specifically, if the absolute value of the difference in received phase signals is less than 90°, the output of a phase detector causes the control unit to pass both received signals to a summer that linearly combines them prior to demodulation.          Otherwise, the control unit inverts the phase of one of the received signals prior to passing both received signals to the summer.
