Abstract: An exercise biased weight includes a weight body defining a center of mass and a through offset bore formed at the weight body at a position offset to the center of mass thereof, wherein a diameter of the offset bore is slightly larger than a diameter of a weight bar member for enabling the weight bar member to slidably pass through the offset bore so as to retain the weight body at the weight bar member. Therefore, the weight body is lifted to generate a downward weight force to against an unwanted shaking movement of the weight body.

Abstract: During transmission, a speed of ultrasound pulses gradually reduces due to acoustic impedance. A length and a density and a sound speed of the ultrasound pulses decide their average speed in the transmitting medium, frequencies, sound intensity and detecting depth. Time of flight (TOF) and TOF shift can be used to calculate the depth and moving speed of detecting objects. Calculating a speed of moving objects by simultaneously detecting TOFs at one detecting site from two separated piezoelectric (PZT) elements improves the testing results with accuracy, simplification and reproducibility. Coding ultrasound pulses to obtained the TOF and the TOF shift can be used to simultaneously calculate the depth and the moving speed of the objects, which also avoids a problem of an aliasing for highly moving speed of the objects. Coding ultrasound pulses also improves the quality of the imaging.

Abstract: During transmission, a speed of ultrasound pulses gradually reduces due to their energy loss from acoustic impedance. A thickness and a density of piezoelectric (PZT) elements and a sound speed in the PZT elements decides energy of the ultrasound pulses and their detecting depth. A speed of moving objects and an angle of the moving objects with the ultrasound pulses may change a speed of reflected ultrasound pulses and affect their time of flight (TOF) and TOF shift. A method of Coding ultrasound pulses combines advantages of a continuous wave ultrasound and a pulsed wave ultrasound. So, it can be used to obtained the TOF and the TOF shift and calculate the depth and the moving speed of the detecting objects, which also avoids a problem of an aliasing for highly moving speed of the objects.

Abstract: A method and apparatus for processing input data signals transmitted in a continuous mode, or in a burst mode, of signal transmission, such as in a satellite or a computer network communications system. A receiver receives input data signals and a buffer stores the received input data. Processing circuitry generates frame timing synchronization control signals for writing the frames of the input data for storage, generates timing error control signals corresponding to a processing delay for the input data, for synchronizing reading out the stored data from the buffer based on a timing difference between the timing error control signals and the frame timing synchronization control signals to adjust for an arbitrary delay in processing the input data. The processing circuitry can include a tap gradient update circuit for generating a tap gradient corresponding to the read out data, based on equalizer error signals generated by the processing circuitry.
