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: A light-guiding pillar has a main body and an LED mount. The main body is a strip pervious to light and has a first surface and multiple refracting grooves formed in the main body at intervals. The LED mount is pervious to light, is mounted securely on and connected integrally with the main body as a single part and has an LED hole and a reflecting surface. The LED hole is formed in the LED mount. The reflecting surface is connected to the first surface of the main body, is inclined relative to the first surface of the main body and is capable of totally reflecting light from the LED hole and making the light travel into the main body. The present invention only requires one LED to provide a wide range of illumination and to use one LED saves cost and electricity.

Abstract: A mattress with airflow-circulating function has a main body and a ventilator. The main body has a crisscross groove formed in the main body. The ventilator is detachably connected with the main body and has a hollow joint, four extending tubes and a curved tube. The joint has five openings. The extending tubes are respectively and securely connected to four of the openings of the joint to form a cross and are mounted in the groove. Each extending tube has multiple apertures formed in the extending tube. The curved tube is securely connected to the other one of the openings of the joint and is mounted through the main body. Accordingly, air can be pumped into the joint and is ejected out from the apertures toward the part of the human body. Therefore, the circulating airflow can massage the part of the human body, relieve the pressure and facilitate blood circulation.
