Patent CA-2090206-A1 (CA)
Inventor: MURATA ERI
IPC: H04N19/50
Filed: 1993-02-23
Abstract: A subtracter (20) supplies a prediction error signal (21), derived from a prediction signal (101) and an input motion video signal (1).  A quantizer (30) quantizes the prediction error signal to generate a quantized prediction error signal (31).  A reproduced prediction error signal (81) reproduced by an inverse-quantizer (80) is added to the prediction signal by an adder 90, and the sum is supplied to the predictor (100), which generates the prediction error signal.  The quantized prediction error signal is converted by a variable word length coder (40) into a variable word length code sequence.  A generated information quantity calculating section (50) counts the number of bits in the sequence frame by frame.  A quantization characteristic determining circuit (60) supplies, on the basis of the result of counting, a controller (70) with a quantization characteristic candidate signal 61 indicating the candidate of the quantization characteristic to be used in the next frame.  The controller 70 compares the coarseness of the quantization characteristic used in the preceding frame with the quantization characteristic candidate signal, determines the quantization characteristic to be used in the current frame, and supplies a quantization characteristic control signal (75) to the quantizer (30) and the inverse-quantizer (80).

Abstract: A method of microbial enhanced oil recovery for recovering oil from an oil-bearing rock formation (13). A population of aerobic bacteria (16) is introduced into the formation (13) at a position spaced from a production borehole (15). The microorgan-isms are adapted to use oil as a carbon source. Pressurized injection water (17) is introduced into the formation via an injection borehole (10)the water including a source of oxygen and mineral nutrients. The bacteria (16) multiply using the oil as their main carbon source and the oxygen in the injection water as their main oxygen source. In so doing; they dissociate the oil from the rock formation (15) and-the dissociated oil is removed via the production borehole (15) by the injection water.

Abstract: A switched capacitor circuit includes a first capacitor connected between first and second nodes, a second capacitor connected between the first node and an intermediate node, and a third capacitor connected between the intermediate node and ground. A group of m parallel circuits are connected between the intermediate node and the second node. Each of the m parallel circuits has a fourth capacitor and a switch for coupling it to ground or to the second node, depending on a corresponding one of m bits of a N-bit gain control signal. (N-m)parallel circuits are connected between the first and second nodes, each including a fifth capacitor and a switch for charging it, depending on one of (N-m) bits of the N-bit gain control signal. A first sampling switch couples an input voltage to the first node in response to the first phase of a two-phase clock signal, and couples the first node to ground in response to the second phase. A second sampling switch provides charging of a sixth capacitor, connected to the second node, in response to the first phase, and discharges energy from it to an output terminal of the switched capacitor circuit in response to the second phase.

Title: Water-based plural component spray painting system
Inventor: FEITEL ANN
IPC: B05B7/32
Filed: 1994-01-20
Abstract: Abstract of the Disclosure The invention relates to a grounded or isolated water-based plural component system for the electrostatic application of water-based paint.  The invention enables the use of traditional color change systems during use of electrostatic spray devices.  The invention includes an electrically isolated electrically less-conductive component fluid-flow course and an electrically-grounded electrically more-conductive component fluid-flow course.  The electrically more-conductive component fluid-flow course may be additionally electrically isolated at the preference of an operator.  The invention includes an electrostatic spray gun device, a mixing means positioned proximal to the electrostatic spray gun, and a first conduit which holds alternating segments of electrically more-conductive component and electrically less-conductive component.  The alternating segments of electrically less-conductive component and electrically more-conductive component function in series to additively provide a combined resistance which electrically blocks the high-voltage potential generated at the electrostatic spray gun.  This, in turn, effectively isolates the electrically more-conductive component fluid-flow course and electrically less-conductive fluid-flow course from the high-voltage potentials, which significantly improves the safety of an electrostatic spray gun used with water-based paints, while simultaneously permitting the use of a standard color change system.

The carrier displays information on the exposed surface of its base as well as on those of its legs which are configured with spaced and opposite sides but which in one embodiment meet at; right angles and in another embodiment meet at angles between 30 degrees to 60 degrees and preferably 45 degrees.  Ribs, carried by the hanger, form boundaries for the carrier receiving portion of the hanger and serve to retain the information carrier in its unique position.  In one embodiment the information carrier is carried by the hook of the hanger while in another embodiment the information carrier extends from the hanger body and in yet another embodiment the information carrier is disposed between an hanger hook and hanger body.

Title: System and method for testing intensity response of a medical monochrome video monitor
Inventor: HARRISON JOHN R
IPC: G01R29/00
Filed: 1994-04-13
Abstract: The intensity output of a monochrome interlaced video monitor typically used in medical imaging may be tested as follows.  The video card of a computer is controlled to output equal video intensity levels of red, green, and blue for a time sequenced series of different levels.  These video signals are combined and attenuated such that the peak level of the series is about 700mV, which is the industry standard for peak white on a monochrome monitor.  The sync pulses from the video card are adjusted to about -300 mV, which is the industry standard for sync pulses driving a monochrome video monitor and are combined with the combined video signal to produce an intensity test signal for driving the monitor.  The video card is controlled to produce a high line rate to drive video monitors having an (approximately double) high line rate and to produce a low line rate to drive video monitors having (an approximately double) low line rate.

Title: Timing and Automatic Frequency Control of Digital Receiver Using the Cyclic Properties of a Non-Linear Operation
Inventor: SCOTT KENNETH E
IPC: H04L7/02
Filed: 1992-12-08
Abstract: A technique for correcting the sampling time and carrier frequency error in a receiver for digitally modulated signals. Discrete-time, complex-valued samples of the incoming signal are fed to a pair of non-linear operators such as correlators. The first correlator provides a signal having a first phase component related to the symbol timing error and a second phase component related to the carrier frequency error. The second correlator provides a signal having a first phase component related to the symbol timing error and a second phase component related to the negative of the carrier frequency error. The phase components are then separated and detected to extract an estimate of the symbol timing error and the carrier frequency error. In the preferred embodiment, the complex-valued samples are frequency-shifted, before being fed to the correlators, so that the phase components of interest appear at zero frequency. The invention satisfactorily demodulates transmitted digital signals in applications, such as cellular time-division multiple access (TDMA), where they are susceptible to multipath fading.
