摘要： There is provided an optical encoder including a phase shifter circuit and a multiple hysteresis comparators. The phase shifter circuit receives four input signals, and outputs multiple phase shifted signals based on the four input signals. Each of the multiple hysteresis comparators uses a changeable operation hysteresis level to compare a couple of phase shifted signals among the multiple phase shifted signals, wherein the changeable operation hysteresis level is determined corresponding to a signal frequency of the four input signals.

摘要： A scroll wheel decoder includes two fixing bases, a scroll wheel, a rotary disk, and a rotation speed sensor and a rotation direction sensor for determining the rotation amount and rotation direction of the scroll wheel respectively. The fixing bases are provided on a circuit board in a computer mouse to support the rotating shaft of the scroll wheel, for enabling the rotary disk to rotate along with the scroll wheel. The rotary disk has peripheral teeth. The rotation speed sensor projects a first detection signal to be blocked by the teeth sequentially so that a control module can calculate the rotation speed and hence rotation amount of the scroll wheel. The rotation direction sensor projects a second detection signal to the scroll wheel, and the control module can identify the rotation direction of the scroll wheel according to the signal reflected by the scroll wheel.

摘要： An electronic device comprises a housing, a motion sensor configured to sense motion of the housing, and a processor configured to determine an impact geometry based on the motion. A countermeasure system comprises an actuator coupled to an actuated member. The actuated member is operable by the actuator to modify the impact geometry, so that impact energy is redirected away from an impact sensitive component of the electronic device to an energy absorbing component of the electronic device.

摘要： A device for use in determining the rotational speed of a body. The device includes a sensor for detecting the strength of a magnetic field, and a body that is rotatable relative to the sensor about an axis. The body includes circumferentially spaced magnetic regions. The device is arranged so that, during rotation of the body relative to the sensor, the maximum strength detectable by the sensor of a first magnetic field of a first of the magnetic regions is different to the maximum strength detectable by the sensor of a second magnetic field of a second of the magnetic regions.
