Abstract: A light-assisted biochemical sensor based on a light addressable potentiometric sensor is disclosed. The light-assisted biochemical sensor comprises a semiconductor substrate and a sensing layer, which are used to detect the specific ion concentration or the biological substance concentration of a detected solution. Lighting elements fabricated directly on the back surface of the semiconductor substrate directly illuminate the light to the semiconductor substrate, so as to enhance the photoconduction property of the semiconductor substrate. And then, the hysteresis and the sensing sensitivity of the light-assisted biochemical sensor are respectively reduced and improved. In addition, due to its characteristics of integration, the light-assisted biochemical sensor not only reduces the fabrication cost but also has portable properties and real-time detectable properties. As a result, its detection range and the application range are wider.

Abstract: A variable friction hinge has a pintle, a stationary leaf and a washer assembly. The pintle is attached securely to a cover of an electronic device. The stationary leaf is attached securely to a base of the electronic device. The washer assembly is mounted around the pintle and has a stationary abrasion washer and a rotating abrasion stationary washer. The rotating abrasion washer has an eccentric hole engaging the pintle. With the eccentric hole engaging the pintle, the rotating abrasion washer alternatively rubs fully or partially against the stationary abrasion washer. Therefore, the hinge provides variable friction.

Abstract: A variable friction hinge is mounted between a cover and a base of an electronic device and has a pintle, a stationary leaf and a washer assembly. The pintle is connected to the cover. The stationary leaf is connected to the base and has an activating panel with an activating edge. The washer assembly has a movable washer, an abrasion washer and a biasing member. The movable washer selectively abuts the activating edge of the activating panel and has an elongated hole slidably mounted securely around the pintle. The movable and the abrasion washers have teeth corresponding to and selectively engaging each other, causing less friction when engaged and more friction when disengaged. When rotated the movable washer selectively disengages the teeth causing the hinge to have greater friction when being rotated one way than the other.

Abstract: A hinge has a pintle, a stationary leaf, a first limiting washer, a first positioning washer and a second positioning washer. The stationary leaf is mounted rotatably around the pintle. The first limiting washer is mounted securely on the pintle adjacent to the stationary leaf and has a limit. The first positioning washer is mounted around the pintle, is connected securely to the stationary leaf and has a protrusion and a detent. The protrusion corresponds to and selectively abuts the limit of the first limiting washer. The second positioning washer is mounted securely on the pintle and has a detent being selectively attached to the detent of the first positioning washer. The rotating angle of the pintle relative to the stationary leaf is limited by the limit of the first limiting washer abutting the protrusion of the first positioning washer.
