Abstract: Provided is an electromagnetic induction potentiometer adaptive for full-stroke detection, including a movable element configured to obtain an input for position change, a permanent magnet attached to the movable element, a magnetic induction sensor configured to sense positions of the permanent magnet and generate an initial potential signal, and an full-stroke adaptive output adjusting unit configured to collect the initial potential signal and adaptively adjust the initial potential signal to an actual potential signal corresponding to a full stroke of position changing of the movable element.

Abstract: An electromagnetic induction potentiometer includes a housing, a rotor, a permanent magnet, and a magnetic induction module. The housing defines a first cavity and a second cavity. The rotor is accommodated in the first cavity. The rotor is rotatable relative to the housing. The magnetic induction module is accommodated in the second cavity. The rotor includes a through hole and fasteners. The through hole is configured to receive an external rotation input. The fasteners are configured to fix the permanent magnet on the rotor. Through arrangements of the fasteners, the permanent magnet is firmly installed on the rotor, preventing the permanent magnet from falling off the rotor when the electromagnetic induction potentiometer is in a work state, improving working stability of the electromagnetic induction potentiometer, and making the permanent magnet easy to disassemble and assemble during production ad testing processes of the electromagnetic induction potentiometer.

Abstract: Disclosed are a cell and a secondary battery. The cell includes a cell body; a length of the cell body is L, and a thickness of the cell body is H; and the L and the H satisfy the following relational expression: L/H>7. According to the cell and the secondary battery provided in the disclosure, by reasonably designing a relationship between the length L and the thickness H of the cell body, that is, a ratio between the length L and the thickness H of the cell body is defined within a specific relational expression of L/H>7, the heat dissipation performance of the cell is improved, and the heat inside the cell is discharged to the outside timely, such that the service life and safety performance of the secondary battery are improved, thereby having a higher potential for market promotion.

Abstract: A dynamic sampling method for an analog sensor and devices thereof are disclosed. The method includes reading a predetermined sampling range, taking a minimum value of the predetermined sampling range as a minimum value of an actual sampling range, and taking a maximum value of the predetermined sampling range as a maximum value of the actual sampling range; sampling an output of the analog sensor to obtain an analog sampling value; outputting an actual sampling value according to a comparison result between the analog sampling value and the actual sampling range; and adjusting the actual sampling range according to the comparison result between the analog sampling value and the actual sampling range. The dynamic sampling method realizes a dynamic adjustment of the actual sampling range of the analog sensor. When the analog sampling value exceeds the predetermined sampling range, the actual sampling range is timely and dynamically updated.
