Abstract: A force measuring system for exercise equipment provided for using in an exercise equipment, the system includes a measured body, a force sensor, a circuit board; a Wheatstone bridge, a data transmission module and a power module disposed on the circuit board; and a receiving device. The power module provides a working power supply. The measured body is connected to the exercise equipment. The force sensor is disposed on the measured body, and the resistance value thereof changes along with a deformation amount of the measured body. The Wheatstone bridge is electrically connected to the force sensor to output a measurement signal. The data transmission module transmits a force taken information to the receiving device, wherein the force taken information is obtained according to the measurement signal.

Abstract: A flywheel torsion measuring device with internal power, applied to a shaft and a flywheel of sports equipment, has a wheel connector, a power unit, a torsion measuring element and circuit boards. The wheel connector, for fastening the flywheel and connecting the shaft through a bearing, has an assembly space and an annular plate. The power unit provides a power. The torsion measuring elements are disposed on the annular plate of the wheel connector, and the circuit board, which is disposed in the assembly space of the wheel connector and electrically connects the power unit and the torsion measuring elements, converts the power into a working power for the torsion measuring element. The wireless transmission module of the circuit board transmits the measurement information generated by the torsion measurement component to the outside.

Abstract: A pulse data coding method for wireless signal transmitting and receiving devices includes the steps of using a transmitter to transmit a signal of pulse data to be transmitted, transmitting at least one identification code pulse signal after a predetermined time interval from the transmission of the pulse data signal, and transmitting a check code pulse signal after another predetermined time interval from the transmission of the identification code pulse signal. The check code pulse signal is obtained by coding the pulse data signal and the identification code pulse signal according to a predetermined coding process. When a corresponding receiver receives the signal from the transmitter, it determines a correctness of the received signal according to the predetermined coding process, which may be an algorithm of addition, subtraction, multiplication, division, and/or a ratio operation.

Abstract: A novel mechanism of wireless heartbeat transmitter is composed of a body having an integrated structure, an upper cover, a circuit board, a battery, and a battery cover, which said body integrates the front section of conductible rubber monitoring the heartbeat signal and the shell having its interior accommodating the circuit board into one mechanism so that the front section of said conductible rubber becomes a part of internal mechanism of said shell to reach a superior effect of waterproof and dustproof and form a mechanism of electrical connection or conductible path by directly surface to surface touch of circuit board and conductible rubber.

Abstract: A braking assembly with self-generating power energy is provided with a plurality of permanent magnets arranged around a rotary central shaft of the braking assembly to alternate N poles and S poles, at least one power-generating coil provided on a stator of the braking assembly nearby the permanent magnets for generating an induced electromotive force when the rotary central shaft rotates, a pulling mechanism provided on the stator for pulling two free ends of two curved braking plates mounted on the stator depending on the induced electromotive force generated by the power-generating coil and thereby regulating a brake force of the braking assembly, and at least one compression spring provided between each of the curved braking plates and the stator to provide a radially outward restoring force to the curved braking plates.
