Title: Arrangement for accurately sensing voltage of a high-impedance source and supplying power to a variable burden
Inventor: ZULASKI JOHN A
IPC: H02H1/06
Filed: 1992-09-17
Granted: 2001-04-10
Abstract: An arrangement is provided for accurately sensing the source voltage of a high-impedance source while supplying a variable burden. A current-sensing element is connected in series with a load circuit across a high-impedance source. The load circuit includes a variable burden load. A shunt regulator is connected with the variable burden load and is arranged to operate so that the combination of the shunt regulator and the variable burden present a controlled, nearly constant burden to the high-impedance source. The source voltage of the high-impedance source is sensed via the voltage across the series current-sensing element. While the output voltage is directly proportional to the burden, the output current is essentially unaffected by small variations in the burden. Thus, the current through the series current-sensing element is utilized to accurately sense the voltage of the high-impedance alternating-current source while also supplying the variable burden load such as a battery, electrical circuitry, and a switch operator.

Granted: 1995-10-10
Abstract: A latch mechanism (124) for latching a convertible top header to a windshield header (38) includes an electric motor (26) mounted centrally on the top header (120) which is drivingly connected by flexible drive shafts (96, 98) to side-rail-mounted latch units (28, 30). Each latch unit includes a transmission connected to a drive shaft and an output drive screw (84) which drives a drive nut (82) and an attached drive link (64). The drive link is pivotally attached to a side-rail-mounted bell crank (50) that is pi-voted to a J-hook (42). Selective operation of the electric motor will cause the drive screw (84) to shift the drive nut (82) and drive link (64) to move the J-hook (42) between an extended and retracted positions. In extended position, the J-hook can be retracted to engage a windshield header abutment to latch the headers together, or retracted within the side rail for top retraction.

Abstract: The present invention features an apparatus and a method for both extending and folding the ties of a tie bag into the body of the bag.  The apparatus and the method of this invention fold the ties while the webbing of the bag is rapidly moving.  The folding apparatus facilitates passing the U-shaped webbing of the bag through a web-separating device.  The two halves of the webbing are then separated, and each half of the U-shaped web is passed over a guide member.  Each guide member forces the respective tie of each respective web half to fold under.  Thereafter, two additional guide members rejoin the two web halves, with the tie folded in.  The ties are maintained in a smooth, folded-in configuration during the sizing, cutting and final packaging into a stack of individual bags.

Abstract: An auxiliary video information decoder, for decoding auxiliary video information signals such as closed caption data, in-cludes a data slicer (210) having a variable slicing level. The slicing level is adjusted in response to the amplitude of a run-in-clock (RIC) signal that is included in the auxiliary video information portion of the video signal. Slicing level adjustment involves averaging the RIC signal amplitude during a substantially integral number of cycles of the RIC signal that occur during a control interval (RICWND). The timing of the RIC signal waveform with respect to the control interval is evaluated to verify that the de-sired number of cycles of the RIC signal occur during a control interval. The timing evaluation operation involves counting (250) cycles of the RIC signal during a control interval. If the desired number of cycles do not occur, the timing of the control interval is modified (200, 220, 230) with respect to the RIC signal and the timing is reevaluated during a subsequent control interval. The evaluation and timing-modification operations may be repeated until the desired number of cycles of the RIC signal are detected. If repeated operation does not provide the desired result, a control signal may be generated indicating that the video signal may not include auxiliary video information.
