Title: Method and apparatus for inverse quantization of MPEG-4 video
Inventor: CHEN XUEMIN
IPC: H04N7/50
Filed: 1999-04-27
Granted: 2003-01-30
Abstract: Inverse quantization (36, 44, 60) of a two-dimensional array of video coefficients QF[v][u] is provided. A first weighting matrix {overscore (W)}[0][v][u]=2*W[0][v][u] for intra-coded macroblocks and a second weighting matrix {overscore (W)}[1][v][u]=2*W[1][v][u] for non-intra-coded macroblocks are pre-computed and stored (88). A quantization difference (quanti+1)to be used in selecting a weight factor is computed (70) based on a current macroblock quantization level. The weight factor is output from one of the weighting matrices in response to the quantization difference and a macroblock type identifier (66) (i.e., intra-coded or non-intra-coded). Subsequent weights Wi+1[w][v][u] are then computed (86) from a current weight Wi[w][v][u] and the weight factor. The array of coefficients QF[v][u] is multiplied (92) by the weights Wi+1[w][v][u] to reconstruct unquantized coefficients.

Title: Belted crawler having auxiliary drive
Inventor: MORIARTY KEVIN J
IPC: F16H61/452
Filed: 1990-01-25
Granted: 1993-07-20
Abstract: ABSTRACT OF THE DISCLOSURE The invention is directed to an auxiliary drive system for the front wheels of a belted track crawler.  The auxiliary drive wheels and the main drive wheels are provided with overrunning clutches.  In the first two embodiments a mechanical system is used to drive the auxiliary wheels.  In the third embodiment electric motors are used to drive the auxiliary wheels.  With all the systems when the crawler is being driven forward the auxiliary drive wheel is driven slower than the main drive wheel.  In a no slip situation the auxiliary drive wheel freely rotates at the speed of the main drive wheel.  When sufficient slippage occurs between the main drive wheel and the track, the auxiliary drive wheel is driven at the slower speed driving the track.  In reverse, the auxiliary drive wheel is driven faster than the main drive wheel.  In a no slip condition, the auxiliary drive wheel drives the crawler in reverse.  When sufficient slippage occurs between the auxiliary drive wheel and the belted track, the main drive wheel again drives the crawler.

Granted: 1993-11-09
Abstract: ABSTRACT OF THE DISCLOSURE A bipolar analog voltage is converted into a digital signal by sensing the polarity of the voltage and selectively supplying a bias voltage to an analog-to-digital converter, which can preferably be a charge balanced voltage to frequency converter, as a function of the sensed polarity. The voltage to frequency converter has a double valued variable frequency output with a discontinuity at zero volt such that the converter derives a maximum output frequency for a maximum positive voltage and also for a negative value slightly displaced from zero; the voltage to the frequency converter minimum output frequency is derived from positive voltages slightly greater than zero and for maximum negative voltages.   The converter output frequency and the sensed polarity are supplied to a frequency to digital converter which derives an output signal having a bit representing the polarity of the analog voltage and additional bits indicative of the magnitude of the analog voltage.

Abstract: VECTOR QUANTIZER SEARCH ARRANGEMENT Abstract In an arrangement for coding multi-element signals such as used in speech or image processing, a plurality of N element reference signals representable in a prescribed vector space are stored. An N element input signal representable in the prescribed vector space is received and one of the reference signals is selected to represent the input signal. A set of signals each representative of the projection of one of the reference signals on a predetermined orientation in the prescribed vector space and a signal representative of the projection of the input signal on the predetermined orientation are formed. The reference signals are arranged according to their projections on the predetermined orientation. Candidates for the best matching reference signal are selected according to the differences between their projections on the prescribed orientation and the projection of the input signal on the prescribed orientation and the projection difference signals are utilized to determine the reference signal closest to the input signal in the prescribed vector space.

Granted: 2001-04-03
Abstract: A sampling pump is provided suitable for pumping a discrete quantity of either a liquid or a gas per pump stroke from a flow line to a sample vessel. An operator unit drives a piston within the pump bore, and controls the stroke of the piston and thus the quantity of fluid pumped per stroke. A balanced check valve mechanism controls flow from the pump bore to the pump outlet port, and is provided within and carried by the piston. Line pressure acts on the operator end of the piston to assist the operator in driving the piston during its power stroke. A manifold may be secured to the pump body, and has a flow path therein which is in communication with the inlet port to, the pump bore.      The pump may also be used for injection purposes to introduce a selected quantity of fluid to a high pressure line.

Granted: 1995-12-12
Abstract: A barrier for use with a rod extending into a bore having a cross sectional dimension, formed in a structure.          The barrier is located on one side of a fluid supply in the bore.  The barrier includes a sealing portion adjacent the fluid supply, the sealing portion has a flexible flange in sealing contact with the bore.  A tube is connected to the sealing portion and has a rod passageway formed there through.  A diameter of the tubular portion is smaller than the cross sectional dimension prior to insertion of the rod, and expands to conform to the cross sectional dimension in response to insertion of the rod.  A rupture portion is connected to the tubular portion, and seals the rod passageway to limit a passage of fluid therethrough prior to insertion of the rod.  The rupture portion is adapted to rupture in response to penetration by the rod.  The barrier may be used in conjunction with a dynamic earth anchor, to prevent passage of the grout to between the anchor and the bore.

Granted: 1994-05-31
Abstract: ABSTRACT OF THE DISCLOSURE    An automatic output power controller controls signals output by an amplifier amplifying a modulated wave with its envelope varying due to the modulation so that the mean power becomes constant.  An equi-output point extraction means extracts timing of the output power of the amplifier becoming a constant value from a base band signal or the like, and supplies the timing to a sample-and-hold circuit.  The sample-and-hold circuit samples and holds the output power.  Difference between the sample-and-hold value and the reference value is supplied to an output power adjusting means, and the output power adjusting means controls signals output by the amplifier in accordance with the difference so that the mean power becomes constant.
