摘要： The present disclosure provides a liquid crystal lens, a controlling method thereof and a 3-Dimensional (3D) display using the same. The liquid crystal lens includes a pair of electrode structures which are arranged apart from each other; and a liquid crystal layer which is arranged between the pair of electrode structures and includes a plurality of liquid crystal molecules aligned in an initial aligning direction in which the liquid crystal layer has a non-lens effect. The pair of electrode structures are arranged to generate a first electric field which is used to change aligning directions of the liquid crystal molecules to make the liquid crystal layer have a lens effect. The pair of electrode structures are further arranged to generate a second electric field which is used to make the liquid crystal molecules revert to the initial aligning direction.

摘要： A power supply device is provided. The power supply device provides a maintenance voltage at an output terminal to a system chip of a system and includes a first battery, a capacitor, a charging circuit, and a monitoring circuit. The first battery provides a battery voltage. The capacitor stores a capacitor voltage. The charging circuit is coupled to the capacitor. The monitoring circuit detects whether the battery voltage is less than a first threshold and whether the capacitor voltage is larger than a second threshold and generates a control signal according to the determination result. When the monitoring circuit detects that the battery voltage is less than the first threshold and the capacitor power supply device voltage is not larger than the second threshold, the monitoring circuit asserts the control signal to control the charging circuit to charge the capacitor.

摘要： 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.

摘要： An angle-limiting hinge has a stationary leaf, a pivoting leaf, a pintle and a limiting element. The pintle is mounted statically in the stationary leaf and rotatably in the pivoting leaf, thereby allowing the leaves to rotate relative to each other and the pintle has a limit. The limit is C-shaped, formed diametrically around the pintle and comprises two ends being positive stops. The limiting element is mounted around the pintle and is secured to the pivoting leaf and has a limiting block mounted securely in the limiting element using riveting. The limiting block is disposed between the positive stops of the limit to limit relative rotational angles of the leaves. Accordingly, the angle-limiting hinge fastens and facilitates fabrication and is capable of limiting the rotational angle of the leaves.

摘要： 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.

摘要： An antenna body of a broadband inverted-F antenna is printed on a circuit board, wherein an interval is maintained between the antenna body and a grounding plane disposed at a position proximate to an edge of the circuit board. The antenna body is divided into a first, a second and a third portions. An end of the first portion is extended towards the grounding plane to form the short circuit line, and another end of the first portion is extended towards the grounding plane to form the feed line. A first end of the second portion is connected to another end of the first portion, a second end of the second portion is connected to an end of the third portion, and the first portion has a wire width smaller than the third portion, so that no metal is existing between the second and third portions and the grounding plane.
