摘要： A power-assisted bicycle having a sensor with multiple magnet positions and magnetic fluxes unevenly distributed in a shell includes a sensor which includes a sensing element, a power assistance model processor (21), a digital-to-analog converter (DAC, 27) and an operational amplifier (OPA, 28) which are connected successively. The sensing element includes a rotary wheel (1), a static wheel (40), permanent magnets (2) and a Hall component (3) which are embedded within a hollow internal of the rotary wheel and said static wheel. On the rotary wheel (1), magnetic poles of the neighboring permanent magnets (2) are opposite; the permanent magnets (2) are spaced differently and have different magnetic fluxes. The Hall component (3) on the static wheel (40) is provided in proximity to the permanent magnets. The sensor is sleeved onto a middle shaft (51); the OPA (28) is connected to a motor controller (29). Relative positions between the permanent magnets (2) and the Hall component (3) are fixed; the Hall component (3) obtains a rectangular wave signal, which facilitates outputting a manually manipulated power assistance model by the sensor via digitization, providing a reasonable origin, end and strength of power assistance and accomplishing an optimized man-machine match to save electricity.

摘要： A flexible optical displacement encoder configuration uses a source grating to illuminate a scale with structured light such that light from the scale is modulated with a beat frequency envelope which may have a relatively coarse pitch that matches a desired detector pitch. An imaging configuration provides spatial filtering to remove the high spatial frequencies from the modulation envelope to provide a clean signal in the detected fringe pattern. This combination of elements allows an incremental scale track pattern with a relatively finer pitch (e.g., 4, 5, 8 microns) to provide fringes with a coarser pitch (e.g., 20 microns) at a detector. Various scale resolutions can use a corresponding source grating such that all combinations can produce detector fringes that match the same economical detector component.
