Abstract: A stemless operation mechanism includes a case, a first moving component, a second moving component and a detection module. The case includes a first accommodating area, a second accommodating area and a partition portion used to provide an airtight isolating function. The first moving component is movably disposed on the first accommodating area and includes a first magnetic unit. The second moving component is movably disposed on the second accommodating area and includes a second magnetic unit located on position corresponding to position of the first magnetic unit. The second magnetic unit is cooperated with the first magnetic unit to generate a magnetic attraction force or a magnetic repulsion force. The detection module is disposed adjacent to the second moving component, and adapted to detect a movement of the second moving component for determining an operation behavior applied for the first moving component.

Abstract: There is provided a wearable device including at least one light source, a light sensor and a processor. The processor generates a peak interval plot according to one of at least two light detection signals detected by the light sensor when the at least one light source emits light, and generates an oxygen saturation plot according to two of the one of at least two light detection signals detected by the light sensor when the at least one emits light. The processor further determines an Apnea Hypopnea Index (AHI) score according to the peak interval plot, determines an Oxygen Desaturation Index (ODI) score according to the oxygen saturation plot and fits an obstructive sleep apnea level index corresponding to the AHI score and the ODI score.

Abstract: There is provided an optical sensor including an SPAD pixel array, multiple counters and a processor. The multiple counters count photon events of the SPAD pixel array to output an event-based vision sensor (EVS) frame per EVS period. The processor determines an index state of each pixel of the SPAD pixel array by comparing a counting value of each pixel respectively at a predetermined number of checking points with two predetermined thresholds, and calculates an index change of the index state associated with each pixel between adjacent EVS frames. The processor further changes the EVS period and/or adds a count offset to the counting value of each pixel to improve sensitivity of the event-based vision sensor.
