Abstract: A method of processing seismic data including pressure data and pressure gradient data to obtain gradients of moveout corrected pressure data, comprising applying a move-out correction function to the pressure gradient data; and adding a correction term dependent on a moveout corrected time-derivative of the pressure data and a spatial derivative of the moveout correction function. The method may be used prior to any data processing algorithm which uses pressure gradient data in which moveout correction is applied prior to the algorithm, either because the algorithm makes a zero offset assumption or because it is beneficial for the algorithm to operate on moveout corrected data to reduce aliasing.

Abstract: A method for spatially interpolating pressure values of seismic data uses known values of pressure and spatial derivatives of pressure at a plurality of irregularly spaced locations along the direction of interpolation. The interpolation preferably uses an interpolation operator calculated by assuming that an interpolated pressure value comprises a linear combination of the known pressure values at locations xi and the spatial derivatives at locations X?, with operator coefficients wi and w? respectively, and calculating the coefficients by minimizing an error function.

Abstract: A hydraulic braking system for a vehicle incorporating a vehicle dynamics control system (VDCS) includes an electromechanically actuated brake master cylinder that hydraulic braking system detects a reduction in the brake pressure of the wheel brake device, caused due to intervention of the VDCS in the braking operation, and moves a piston of the brake master cylinder in a direction opposite to an actuating direction. This causes an additional flow of the brake fluid from a reservoir to one or more pressure chambers of the brake master cylinder, thus, avoiding the piston from reaching a stop condition, and hence, avoiding an inadequacy in the volume of the brake fluid available in the pressure chambers of the brake master cylinder.

Abstract: A method for predicting a plurality of surface multiples for a plurality of target traces in a record of seismic data acquired in a survey area. The method includes selecting a target trace and identifying two or more desired traces for multiple prediction based on the target trace. After identifying the desired traces, the method identifies one or more recorded traces for each desired trace. Each identified recorded trace is described as being substantially close to one of the desired traces. The method then includes correcting the identified recorded traces for one or more geometry-related effects associated with the survey area and convolving the corrected recorded traces to generate a plurality of convolutions. After convolving the corrected recorded traces, the method then stacks the convolutions.

Abstract: A method for reducing the braking distance for a vehicle having an anti-lock braking mechanism (ABS) and a hydraulic braking system detects a brake pressure requested by the vehicle's driver (Prequested), and calculates the brakes pressure values at which the wheels of the vehicle lock. A maximum brake pressure value of these different brake pressure values is then compared with the driver's requested brake pressure value (Prequested). If the requested brake pressure value is much higher than the maximum brake pressure value, then the actual brake pressure applied at different wheels (Pactual) is set to a level below the requested brake pressure (Prequested), but still higher than the maximum brake pressure value. This reduces the amount of work required to be done by the ABS in pumping the excessive brake fluid out of the braking system of the vehicle, and allows for precise control of ABS mechanism during wheel slip conditions.

Abstract: A technique includes obtaining seismic data acquired by seismic sensors of a composite seismic signal that is produced by the firings of multiple seismic sources.

The technique includes simultaneously determining the models based on the modeling and the desired constraints. The datasets are generated based on the determined models. Each dataset is indicative of a component of the composite seismic signal and is attributable to a different one of the seismic sources.
