Abstract: A modular potentiometer includes a magnetic block slide unit including a slide and a magnetic block disposed on the slide; a magnetic field sensing unit parallel to the magnetic block slide unit and including at least one Hall device and a circuit board electrically connected to the at least one Hall device, wherein the circuit board is modularized so that portions thereof are connected in series; a signal processing unit electrically connected to the magnetic field sensing unit to receive a sensing signal from the magnetic field sensing unit and thereby calculate a distance traveled by the magnetic block. Hence, due to the aforesaid segmental design, the non-contact potentiometer is easy to manufacture, mount, demount, and carry, and its manufacturing cost is reduced by modularizaton.

Abstract: A multi-tier limit-angle protection device detects a rotation angle about a rotation axis of a driving apparatus to thereby control the operation of a driving motor of the driving apparatus. The multi-tier limit-angle protection device includes a first-axis potentiometer for generating a first-axis sensing signal, a first-axis limit-angle detecting module for generating a first-axis confirming signal, and a controller. The controller effectuates a first tier protection mechanism by determining whether a limit angle of the rotation axis is exceeded according to the first-axis sensing signal, effectuates a second tier protection mechanism by determining whether the first-axis potentiometer is operating well according to a first-axis confirming signal, and effectuates a third tier protection mechanism through its control over the driving motor. The multi-tier limit-angle protection device features integration of software and hardware to thereby preclude mechanism complexity and provide a multi-tier limit-angle protection mechanism.

Abstract: A non-contact adjustable hysteretic magnetic encoder includes a bipolar magnetic block, two magnetic sensing components, a storage, and a controller. After retrieving the current rotation angle by accessing a rotation angle table, the controller determines, by an encoding rule, digital logical values of a first phase signal (A-phase signal) and digital logical values of a second phase signal (B-phase signal) and outputs the digital logical values. The phase difference between a first phase signal and a second phase signal is adjusted, and a hysteresis range, also known as hysteresis angle, is adjusted, according to the grids attributed to the predetermined number of grids before the turning point and the grids attributed to the predetermined number of grids after the turning point. Hence, the non-contact adjustable hysteretic magnetic encoder features enhanced potential of expansion and marked industrial practicability.
