Abstract: A method of operating a global positioning receiver is provided. The method includes receiving a plurality of signals from a plurality of satellites. At least a measurement from and location of each satellite is determined based on the received plurality of signals. An approximate vehicle velocity vector is determined based on the received plurality of signals. A dot product between a line of sight between each satellite and a vehicle having the receiver and the determined vehicle velocity vector is determined. Each measurement associated with each determined dot product that is below a minimum dot product threshold is removed to obtain a resultant set of measurements. A position solution based on the resultant set of measurements is then determined.

Abstract: Various embodiments of apparatuses, systems and methods for regulating the currents provided by a DCDC buck converters to an LED unit are provided. In accordance with at least one embodiment, a device includes a time-off module configured to output a time-off signal when an output voltage of a power supply reaches a predetermined threshold; a timer module configured to determine a first duration, and after waiting a second duration, output a measured time signal; and a control module, coupled to each of the timer module and the time-off module, configured to output a set signal during a current cycle of the power supply, wherein the “on” slate for the current cycle occurs while the control module outputs the set signal and ends when the control module receives the measured time signal.

Abstract: An embodiment of the invention relates to a method of processing seismic data comprising a plurality of traces, each trace having a source position, a receiver position and a midpoint position, each having coordinates in an inline direction and a crossline direction. The invention uses a data set comprising traces having one of the source position, the receiver position or the midpoint position having coordinates which are invariant in one of the inline or the crossline directions. A non-iterative surface related multiple attenuation algorithm is applied to the data set which assumes substantial non-variation of depth of reflectors in the same one of the inline or the crossline directions.

Abstract: A technique includes towing a spread of at least one streamer to acquire seismic data in response to energy produced by a seismic source. The technique includes towing the seismic source at least 100 meters behind a front end of the spread to configure the spread to acquire a split spread gather record.
