摘要： Systems and methods may provide a graphics processor that may identify operating conditions under which certain floating point instructions may utilize power to fewer hardware resources compared to when the instructions are executing under other operating conditions. The operating conditions may be determined by examining operands used in a given instruction, including the relative magnitudes of the operands and whether the operands may be taken as equal to certain defined values. The floating point instructions may include instructions for an addition operation, a multiplication operation, a compare operation, and/or a fused multiply-add operation.

摘要： A golf launching monitoring arrangement allows equipment to be placed at a position behind the player (i.e., behind the golf ball), to measure both club and ball movement. A 3D scan of the club head before the play serves two purposes: 1) 3D registration that enables accurate measurement of the club head position and orientation for the camera system measuring the club movement from the back; 2) for reconstruction of the launching scene. With a 3D model of the club head, a simple 3D model of the golf ball and accurate measurement of their movement during the play, a full 3D golf launching scene can be reconstructed authentically. With this reconstruction, the movement of both the club head and the resulting ball movement can be replayed at any viewing angle, with any frame rate and at whatever resolution for the players or the coaches to view and analyze.

摘要： A method of measuring distance between a target and a receiver in a ranging system may comprise transmitting a first pulse at a first time determined by a sampling clock in a receiver, receiving the first pulse, sampling the first pulse at a predetermined amplitude threshold using the sampling clock and determining the time of arrival of the first pulse in terms of a number of periods of the sampling clock after the first pulse was transmitted. This may be repeated for a second pulse and the average times of arrival of the first and second pulses are determined to obtain an averaged estimated time of arrival. The distance between the target and the receiver may be determined by multiplying the averaged estimated time of arrival by the speed of propagation of the transmitted pulses. There is also disclosed an apparatus for measuring distance.
