Abstract: A control panel for fitness machine includes a control circuit for processing and collecting exercising data, two display units respectively electrically connected to the control circuit and respectively controllable by the control circuit to display exercising data, and two switching buttons electrically connected to the control circuit for operation by the user to drive the control circuit to change the exercising data displayed on the display units.

Abstract: A two-node-type human physiological parameter measuring apparatus includes two pulse sensors each having a contact terminal formed at its external surface, two elastic clamp portions extending downwards from two sides of a bottom of the two pulse sensors, and a clamping space formed between the two clamp portions, two wires, and a central processor electrically connected via the two lead wires respectively with the pulse sensors for inputting and outputting the voltage signal and converting the same by a specific program into data output, for the measurement of heartbeat frequency or body fat quantity.

Abstract: A handle is composed of a left handlebar having a left gripping section, and a right handlebar having a right gripping section. The two gripping sections extend along a longitudinal axle of the handle and are respectively longer than the breath of the user's hand, i.e. the user can hold one of optional positions of the handle. Each of the two gripping sections has at least one contact face extending along the surface thereof. Each of the contact faces is electrically conductive but not in electrical connection with the others. The contact faces are respectively electrically connected to a particular processor of an exercise apparatus, such that the processor can scan the user's human electrical signals, like frequency of potential difference or impedance, and further transform the signals into corresponding human physiological characteristics.

Abstract: A bi-point detection type heart-rate monitor is constructed to include two electrically conductive contact terminals for the touching of the two hands or feet of a person, an amplifier-filter circuit adapted to sample impedance signal between the contact terminals, to amplify the impulse of the sampled impedance signal, and to remove noises from the sampled impedance signal, a waveform converter adapted to rectify outputted waveform from the amplifier-filter circuit into a square wave, and a processing and output circuit adapted to receive and process the square wave signal outputted by the wave form converter, to obtain the mean frequency of peaks of the received square wave signal by means of a computing process, and to output the frequency value thus obtained to a display unit for display.
