摘要： A method for real-time computation of point-by-point apodization coefficients used for beam-forming includes storing apodization coefficients of receiving focus points in memory, and computing at least one of an included angle between a vector from a transducer element to a receiving point and a normal vector of the transducer element, and a trigonometric function value of the included angle. The method also includes addressing the memory storing the apodization coefficients according to the quantized included angle or trigonometric function value, and reading the apodization coefficients. In one embodiment, the method may include computing in advance apodization coefficients of a receiving focus point as the starting point for the subsequent interpolation operation and another receiving focus point as the ending point, and deriving, for each receiving channel, apodization coefficients of the points situated between these two receiving focus points through an interpolation operation.

摘要： A circular arc wide beam transmission method includes setting parameters for a focusing circular arc and calculating a transmission delay for each of the array elements in a transmission aperture of a probe based on the parameters for the focusing circular arc. An ultrasonic imaging system controls each array element to transmit ultrasonic waves according to the transmission delay for that array element.

摘要： A drilling assembly for drilling pipe into a drilling surface using a drill bit. The drilling assembly comprises a power unit, a thrust frame, a means for moving the thrust frame, a rotary and carriage assembly and a microprocessor adapted to control the load on the drill based upon the level of mud pressure in the assembly. The drilling assembly is adapted to drill pipe at any angle relative to the drilling surface between substantially parallel to the drilling surface and substantially perpendicular to the drilling surface. The method comprises providing a such drilling assembly, placing a drill pipe onto the drilling assembly, moving the thrust frame to a desired drilling angle, moving the rotary and carriage assembly into direct contact with the drill pipe, applying rotational, thrust and pull-back forces to the drill pipe, drilling the pipe into the drilling surface and controlling the load on the drill bit.
