Title: Automated stereo synthesizer for audiovisual programs
Inventor: CHACE FREDERIC I
IPC: H04R3/12
Filed: 1988-08-25
Granted: 1992-10-06
Abstract: ABSTRACT OF THE DISCLOSURE          Surround stereo signals are synthesized from the composite or DME monaural sound tracks of audiovisual programs by use of multi-channel, computer-controlled digital circuitry and operator-programmed sound cues, the latter matching video time codes with audio control signals.  The stereo signals have out-of-phase delay components, resulting in compatibility with conventional monaural audio equipment, and steerable pan components, resulting in selective sound placement capability. Variable time delays and variable ratios of dry and delay are used in conjunction with panning movements to achieve a wide variety of acoustical effects, such as resonance, spread and cutting, which correlate the audio portion of the program with the video portion of the program.  An operator selects and programs sound cues and stores them for playback by using a plurality of audio controls and a computer interface which are provided on an operator console.  Subroutines are used for automated cue recording and for editing.  Stereo sound tracks are created from monaural source material.

Granted: 1994-03-15
Abstract: Abstract An auto-threshold circuit  in accordance with the present invention comprises a full-wave peak sensor for accurately estimating slice levels for input signal detection.  The peak sensor is qualified such that the auto-threshold circuit does not track an input signal with no modulation.  The input  signal is windowed with a phase-locked-loop so that the peak sensor is coherent to the input signal, causing the circuit to be insensitive to noise spikes or input distortion outside the window.  The auto-threshold circuit includes a digital loop filter which receives the output from an auto-threshold controller and generates a corresponding binary signal which is converted by a digital Sigma/delta modulator to a single bit pulse density modulated signal having a predetermined sampling frequency.     An adaptive equalizer in accordance with the present invention shares the auto-threshold slicing signal for generating its error feedback signal.  The adaptive equalizer comprises a frequency selector which generates an output signal in response to the input signal and the feedback signal.  As stated above, a threshold comparator slices the equalizer output at predetermined levels.  A controller receives the comparator output and provides a controller output representative of the voltage level of the comparator output.  A digital filter is then utilized to generate a corresponding binary signal as the feedback signal to the frequency selector.  The adaptive equalizer is operable at more than one speed.

Title: Power supply for a television apparatus
Inventor: LENDARO JEFFERY B
IPC: H04N5/63
Filed: 1989-02-02
Granted: 1991-11-26
Abstract: ABSTRACT During a power-up mode of a television receiver power supply, a first run supply voltage is generated by rectifying a retrace voltage in a flyback transformer of a horizontal output stage of the television receiver.  The rectified voltage is coupled through a resistor and a diode to a power supply voltage receiving terminal of a load circuit.  A voltage regulator that includes a pass transistor regulates the voltage at the terminal during both the power-up and standby modes.  During the power-up mode, when the ambient temperature is higher than during the standby mode, the current in the transistor is lowered, as a result of a current that is coupled to the terminal via the diode.  This reduces the power dissipation in the transistor during the power-up mode.  A second transistor, having a base electrode that is coupled to the anode of the diode, generates a second run supply voltage that is temperature compensated at an emitter electrode of the transistor.

Granted: 1994-11-08
Abstract: The invention provides a system for discriminating between modulated backscattered signals based upon trans-mission-to-reception time delay.  The system employs a carrier, phase-modulated with a modulating signal, having character-istics which provide unity output when correlated with itself with zero time shift and a substantially lower output level when correlated with itself with a significant time shift.  The system works with a backscatter-modulator located a finite distance from the transmitter for receiving and modulating the backscatter of the carrier.  A receiver/detector receives and detects the modulated backscattered phase-modulated signal, the detector being phase-sensitive and having as a reference signal the transmitted phase-modulating carrier signal, and having as an input signal the phase modulated backscattered carrier.  The detector provides an output signal whose averaged amplitude is substantially dependent upon the degree of phase correlation between the phase of the modulation returned input signal and the reference signal.  Finally, the output signal from the detector is selectively processed only when its averaged amplitude is above a threshold level.  In a preferred embodiment, the transmitted signal is a spread spectrum signal. A preferred application is in signal discrimination in toll road collection lanes.

Title: Waterflow differential electrical charging process for ores
Inventor: BAREFOOT ROBERT R
IPC: C22B1/00
Filed: 1989-09-21
Granted: 1994-12-27
Abstract: The invention consists of  forming an aqueous slurry of water and particles of ore carrying both metals and/or minerals which are passed at relatively high speed along an electrically isolated path in contact with elec-trically insulating materials and in the presence of air.          This  generates  a positive  electrostatic  charge in the water  droplets  and  enclosed  particles  and  a  negative charge in the electrically insulating materials through which they are being driven.  The water droplets and hence the particles become differentially charged so that when they pass over an oppositely charged negative field, they are driven into the lower oppositely charged field both by the  strong  force  of  electrical  attraction  and  the relatively weaker force of gravity.   Should the negative collector contain an amalgamating material such as mercury and the ore,  as an example contain gold, electrons are exchanged providing instant amalgamation of the surface of the gold.  The electrostatic charge is maintained through-out the process until precipitation of the particles is completed.

Abstract: An angling device for trolling a pair of fishing lures in spatial relation increases the separation between a conventionally hooked game fish and the free lure to prevent foul hooking the fish.   In one embodiment, the device comprises a wire spreader that includes a pair of opposing coaxial arms having free ends to which the lures are connected by short leaders, and a central arcuate track that joins the arms.  The device and lures are trolled through the water using a carrier having an eyelet at one end connected to a fishing line, and either a slider or roller at an opposite end that captively engages the track and is positionable therealong.  When a game fish strikes one of the lures the carrier is displaced along the track such that the arms rotate, causing the hooked fish to trail behind the free lure which is drawn forwardly.  In other embodiments of the device, a thin flat plate with a convexly curved leading edge replaces the wire spreader, and the arcuate wire track is replaced by an arcuate slot.
