Abstract: An apparatus and method for compressing an input sequence of data items produced by sampling a periodic waveform compresses such input sequence by searching a history buffer operable to store consecutive data items, to locate a stored sequence of consecutive data items matching the input sequence. Matching is deemed to occur when each data item in the input sequence is within non-equal upper and lower limits of its corresponding data item in the stored sequence. When a stored sequence matching the input sequence is located compressed output data is produced to represent the stored sequence and the stored sequence is again stored in the history buffer to succeed the data items already stored therein. When a stored sequence matching the input sequence is not located, a representation of the first data item in the input sequence is produced and the first data item is stored in the history buffer to succeed the data items already stored therein. In addition, there is disclosed a system employing the above compression method in combination with a decompression method.

Title: Method and apparatus for decoding manchester encoded data
Inventor: WIGHT MARK STEPHEN
IPC: H04L25/40
Filed: 1992-09-30
Granted: 1998-07-14
Abstract: A receiver for Manchester encoded data includes an autocalibration feedback loop that generates a timing pulse used to recover the clock and data signals. The autocalibration feedback loop includes a first digital delay line (12) sampled by a plurality of D-type flip-flops (52) in dependence upon the recovered clock signal (RCLK) to produce a control word CNT(O:N) indicative of the number of digital delay elements (50) required to approximate one-half of the recovered clock period. A second digital delay line (14), connectivity mapped (58) to the first, provides three-eights of a clock period delay. The delayed clock signal (DCLK) is derived from the bit stream by sampling in dependence upon the timing pulse (TPLS). The decoded data signal (RDATA) is derived from the bit stream by multiplexing the sampling input in dependence upon the timing pulse and the decoded data signal.

Title: Hybrid valving system for varying fluid flow rate
Inventor: GORDON DANIEL J
IPC: G01N21/31
Filed: 1994-06-22
Granted: 2000-08-15
Abstract: In a fluid valuing system, binary fluid control lines are connected in parallel between a common fluid inlet and a common fluid outlet. Each line has a binary valve and a metering orifice for passing a predetermined rate of fluid flow. The rates are in a geometric progression in factors of two. An analog fluid control line is connected in parallel with the binary lines, and has a continuously adjustable flow rate regulator for passing any selected rate of fluid flow up to a maximum at least equal to the largest increment of rate change in the binary lines. The regulator is formed of a miniature solid state device. A controller sets each binary valve open or closed, and sets the regulator for a selected flow rate, such that cooperative settings provide for a smoothly variable rate of total fluid flow.

Abstract: A power divider (20) includes two orthomode tee to cylindrical waveguide adapters (26, 34) coupled by a phase shift unit (48) having a slow-wave structure (68) located in a sidewall (82) of a waveguide section (50) at a position located 45 degrees between planes of rectangular ports of the adapters.  The slow-wave structure includes a set of vanes (54) which are movable by means of a motor (58) to adjust their penetration through the sidewall of the waveguide section.  Adjustment of the penetration provides for selection of an amount of differential  phase  lag  introduced  between components  of electromagnetic waves propagating through  the  waveguide  section  between the  two adapters.  Pins (96) are formed integrally with the vanes by a notching of edge regions of the vanes. The pins introduced a relatively small amount of phase shift as compared to that introduced by the vanes.  However, the phase dispersion of the pins counteracts a phase dispersion of the vanes for increased   bandwidth   of  the   power  divider. Adjustment of the phase shift provides for rotation of an electric vector for switching an exit point of an electromagnetic wave between either one of two output ports (30, 32) or for a division among the two output ports in any desired average power ratio.

Title: Method for maintaining encoded coherence for remotely positioned mri device
Inventor: CROWLEY CHRISTOPHER W
IPC: G01R33/561
Filed: 1994-12-13
Granted: 2001-10-09
Abstract: A method for using a remotely positioned MRI device to image a material with an inhomogeneous magnetic field requires maintaining an encoded coherence of all components of nuclear magnetization in the material during the imaging process. To do this, the encoding of nuclei is accomplished first, and then the nuclei are repetitively refocussed'to obtain recordable net magnetic moments. This is repeated as part of a two-step recording sequence wherein first one component of the refocused nuclear magnetization is recorded and then the other component of the refocussed nuclear magnetization is recorded.      Importantly, for each step in the recording sequence the encoding and the repetitive refocussing of the nuclei are accomplish separately. Specifically the method includes the steps of: tilting the nuclei with a 90° pulse; encoding the nuclei with a gradient; pulsing the encoded nuclei with a train of 180° pulses having a first phase angle to generate a pattern of magnetic moments; and recording the pattern. All of this is then repeated using 180° pulses with a different phase angle. The method also contemplates combining a plurality of patterns to create an image of the material.

Title: Fuel filler door actuator assembly with integral kick-out spring
Inventor: MARTUS CHARLES R
IPC: E05B15/16
Filed: 1996-04-02
Granted: 2002-03-19
Abstract: A release mechanism for use with fuel filler door latch systems that provides superior control of door movement during the entire service life of the motor vehicle. The biasing mechanism of the present invention includes a kick-out spring that acts directly against the striker bar. As such, the kick-out spring is not exposed to overstressing and does not cause undue wear of the automobile body. The kick-out spring is a leaf spring having a first end that is secured to the housing, an intermediate section routed between posts extending outwardly from the housing, and a cantilevered second end that is oriented to be engaged and resiliently deflected by the striker bar when the fuel filler door is moved toward its closed position. In the closed position, the striker bar forcibly biases the second end of the kick-out spring to a defected position. Upon release of the striker bar, the kick-out spring acts on the striker bar for urging the fuel filler door to its open position, thereby permitting the kick-out spring to return to its non-deflected position.
