Abstract: A semiconductor device includes a substrate. The semiconductor device includes a fin that is formed over the substrate and extends along a first direction. The semiconductor device includes a gate structure that straddles the fin and extends along a second direction perpendicular to the first direction. The semiconductor device includes a first source/drain structure coupled to a first end of the fin along the first direction. The gate structure includes a first portion protruding toward the first source/drain structure along the first direction. A tip edge of the first protruded portion is vertically above a bottom surface of the gate structure.

Abstract: An intelligent exercise intensity assessing system includes an exercise testing machine, a physiological information sensor, a signal transmitter connected with the physiological information sensor, a central control host connected with the signal transmitter, and a cloud database connected with the central control host. The physiological information sensor senses physiological information of an exerciser before and after the exerciser operates the exercise testing machine. The physiological information is transmitted by the signal transmitter to the central control host, and transmitted by the central control host to the cloud database. The cloud database analyzes the physiological information to obtain a corresponding forecasted watt value, and obtains a resistance level of different fitness apparatuses according to the forecasted watt value.

Abstract: An exercise intensity assessing system includes a physiological information sensor, a signal transmitter connected with the physiological information sensor, a central control host connected with the signal transmitter, and a cloud database connected with the central control host. The physiological information sensor senses physiological information of an exerciser before and after the exerciser exercises. The physiological information is transmitted by the signal transmitter to the central control host, and transmitted by the central control host to the cloud database for being diagnosed and analyzed by a fitness instructor. The cloud database obtains a forecasted watt value corresponding to the physiological information, and obtains a resistance level of different fitness apparatuses according to the forecasted watt value.

Abstract: The present invention discloses an optical disc drive with an explosion proof structure comprising a frame, a first guiding member pivoted to the frame, a second guiding member pivoted to the first guiding member, and a rotating member pivoted to the frame corresponding to an access opening on a side of the frame. When the rotating member rotates to a first position, the access opening is covered by a stopping flange of the rotating member, and when the rotating member rotates to a second position and a compact disc is inserted into the access opening, the compact disc drives the first guiding member and then to drive the second guiding member rotate the rotating member from the second position to the first position. Therefore, a fragment of a cracked compact disc inside the optical disc drive is prevented from jetting out of the optical disc drive effectively.

Abstract: A method of auto-I/Q calibration in modulator and demodulator, including DC cancellation, gain imbalance and phase error calibration is provided for implementation in a front-end circuit without the use of baseband processing signal. In modulator auto-I/Q calibration, the gain amplifier, peak detector, DC gain cell and comparator and auto-I/Q calibration control logic form a calibration loop between modulator output and input buffer. The DC test vectors for their corresponding calibrations are applied to modulator to determine I/Q mismatch. In the calibration loop, the peak detector convert the carrier leakage, differential signal power level caused by the I/Q path gain mismatch and by the local quadrature mismatch into DC signal power level. The comparator is used to measure the DC different on peak deter output under different input test vector.

Abstract: A suspension device for an optical media storage device having a spindle motor. The suspension device includes a loader, a traverse and a dynamic mass. The traverse is disposed on the loader and has a first weighted end. The mass center of the traverse is on the first weighted end and the spindle motor is disposed on the first weighted end. The dynamic mass is disposed on the traverse and has a second weighted end. The mass center of the dynamic mass is on the second weighted end and the second weighted end is located above the first weighted end. Thus, when the spindle motor operates, the vibration of the optical media storage device is reduced tremendously.
