Method And Apparatus For Ac-To-Dc Power Conversion
US Patent:
2014005, Feb 27, 2014
Filed:
Aug 21, 2013
Appl. No.:
13/971910
Inventors:
Robert Rouquette - Covington LA, US
International Classification:
H02M 7/06
US Classification:
363 45
Abstract:
In one aspect, the present invention reduces electromagnetic interference (EMI) caused by a capacitive dropper power supply by synchronizing the openings and closings of a shunt switched used for regulation control of the DC output voltage generated by the power supply, to zero crossings of AC current from the current-limiting resistor disposed in series at the AC input of the power supply. In one or more other embodiments, the capacitive dropper power supply includes disconnect circuitry that senses a loss of the input AC voltage source and in response wholly or partly disconnects internal regulation control circuitry from the supply's output filter capacitor to reduce the current drawn from the filter capacitor, thereby reducing the decay rate of the DC output voltage from the filter capacitor. The contemplated power supply may also be implemented in a Bipolar, BiCMOS or CMOS process, for realization in a compact integrated circuit device.
Seismic System With Ghost And Motion Rejection
US Patent:

Filed:
Jan 21, 2011
Appl. No.:
13/011358

Dale J. Lambert - Mandeville LA, US

International Classification:
G01V 1/38, G10K 11/00
US Classification:
367 24, 367153
Abstract:
An underwater seismic system for reducing noise due to ghost reflections or motion through the water from seismic signals. The system includes two motion sensors. One sensor has a first response and is sensitive to platform-motion-induced noise as well as to acoustic waves. The other sensor has a different construction that isolates it from the acoustic waves so that its response is mainly to motion noise. The outputs of the two sensor responses are combined to remove the effects of motion noise. When further combined with a hydrophone signal, noise due to ghost reflections is reduced.
Electric Utility Meter To Stimulate Enhanced Functionality
US Patent:
2012004, Feb 16, 2012
Filed:
Aug 4, 2011
Appl. No.:
13/198070
Inventors:
Robert J. Rouquette - Covington LA, US
Assignee:
SENSUS USA INC. - Raleigh NC
International Classification:
G06F 19/00, G01R 21/00
US Classification:
702 62, 702 61
Abstract:
The present disclosure replaces a standard electric utility meter with a meter having a signal sensor, signal generator, and processor platform to stimulate broad software and firmware development innovation. The utility can then select the ‘application’ that best suits their analysis needs. The meter platform consists of 3 layers: physical interfaces, pre-processing resources, and applications processing & database. The physical interfaces include voltage, current, and load sensors, radio and PLC communications, optical, and power control for advanced outage management. The increased processing capabilities combined with signal and data processing allow for true distributed intelligence in the smart grid. The physical layer, pre-processing DSP and firmware form open APIs for third party developers.
Multi-Component, Acoustic-Wave Sensor And Methods
US Patent:
2012005, Mar 8, 2012
Filed:

Appl. No.:
13/222563
Inventors:
Robert E. Rouquette - Covington LA, US

Dale J. Lambert - Mandeville LA, US
Assignee:
ION GEOPHYSICAL CORPORATION - Houston TX
International Classification:
G01V 1/38
US Classification:
367 24
Abstract:
A multi-component sensor of a fluid-borne acoustic wave that senses pressure and up to three orthogonal particle motion components. The sensor is unresponsive to motion of the sensor mount. Furthermore, the sensor is substantially unresponsive to the turbulent flow of the acoustic medium past the sensor.
Two-Tier Streamer Communication System
US Patent:

International Classification:
H04L 25/20, H04L 5/14, H04B 13/02
US Classification:
340850, 34087018, 34087026
Abstract:
A two-tier communication system for a seismic streamer. The communication system operates over an unshielded twisted-pair communication line extending the length of the streamer. Repeater units having a repeater function and a device controller function divide the twisted pair into line segments. Coils on each segment couple signals inductively to collocated external devices in a low-speed 2400 baud FSK data link between the devices and an associated device controller. A Gaussian 8-level FSK high-speed 60 kbit/s data link is established along all the segments with the repeaters re-transmitting boosted signals along the entire length of the communication line. The coils are transparent at the high-speed data rate. Time division multiple access (TDMA) or frequency division multiple access (FDMA) is used to accommodate the two links on the single twisted pair.

International Classification:
G08B 1/08
US Classification:
34053913, 34053911, 3404261, 340988
Abstract:
An asset locator device including (a) a wireless receiver capable of receiving an identifier signal transmitted from a short range wireless transmitter device; (b) a wireless transmitter capable of transmitting a message to a space based network; (c) a positioning system capable of determining the location of the locator device; (d) a vibration sensor; and (e) a controller. The controller instructs the asset locator to: (i) attempt to detect the identifier signal from the transmitter device if the vibration sensor senses vibration; and (ii) transmit a signal, including an asset location, to the space based network if: (1) the identifier signal is not detected; and (2) location fixes from the positioning system indicate a location change of the asset.
Gfsk Receiver Architecture And Methodology
US Patent:

Jul 30, 2010
Appl. No.:
12/847951
Inventors:
Robert E. Rouquette - Covington LA, US
Assignee:
Sensus USA Inc. - Raleigh NC
International Classification:
H03D 3/00, H03D 1/06
US Classification:
375334, 375348
Abstract:
A Gaussian Frequency Shift Key (GFSK) receiver includes a receiver front end to receive a GFSK-modulated signal and convert the received GFSK-modulated signal to a baseband frequency modulated signal, a channel filter to reduce channel interference which is adjacent to a desired channel of the baseband frequency modulated signal, a demodulator to demodulate the channel filtered baseband modulated signal and to recover a sequence of symbols, a digital filter to reduce inter-symbol interference (ISI) from the sequence of symbols, a slicer to produce symbol decisions based on the filtered sequence of symbols, and a symbol-to-bit mapper to map the symbol decisions to data bits.
