Abstract: A bracelet includes a first wristband portion having a first connecting end and a first lock end opposite to the first connecting end, a second wristband portion having a second connecting end and a second lock end opposite to the second connecting end, and a lock mechanism. The seconded connecting end is rotatably connected to the first connecting end. The first lock end is connected to the second lock end, thereby locking the first wristband portion and the second wristband portion together to surrounding a receiving space for receiving a user's wrist.

Abstract: The present technology is related generally to a switching mode power supply with virtual current sensing. The switching mode power supply comprises a power stage that includes a first power switch and a second power switch coupled in series. The switching mode power supply senses a first current flowing through the first power switch during on-time and provides a virtual current sense signal that is proportional to a second current flowing through the second power switch during on-time. The switching mode power supply further combines the real current sense signal and the virtual current sense signal to form a current sense signal, which is sent to the controller to realize desired control.

Abstract: A chip card holder includes a base, a first retaining board attached to the base, a second retaining board attached to the base spaced apart from the first retaining board, and a receptacle is defined between the first retaining board and the second retaining board. The first retaining board has a first electrical connector. The second retaining board has a second electrical connector. A drawer is movably received in the receptacle. When the drawer received in the receptacle, the chip cards are retained between the first electrical connector and the second electrical connector.

Abstract: A chip card holder for holding at least one chip card is disclosed. The chip card holder includes a base, a drawer slidably attached to the base and a cover. The drawer defines at least one receiving space, each receiving space for receiving a chip card. The cover is detachably latched to the base to retain the drawer in the base or allow the drawer to be slid out of the base. After the cover is detached from the base, the drawer can automatically partially or completely slide out of the cabinet to expose it from the base, thereby facilitating grasping chip cards out of the receiving spaces or putting the chip cards in the receiving spaces.

Abstract: A chip card holder for holding at least two chip cards is disclosed. The chip card holder includes a base, a drawer slidably attached to the base. The drawer includes at least two receiving spaces, each receiving space for receiving a chip card. The drawer moves relative to the base to make the at least two receiving spaces be exposed out of the base or be received in the base.

Abstract: The present invention discloses a liquid crystal display that includes a plastic frame, a printed circuit board, a pin, a slot, a first constraining part and a liquid crystal panel. The printed circuit board has at least one hole therein. The pin is disposed on the plastic frame. The slot is formed on the pin and extends along the major axis of the pin. The first constraining part is disposed on the side surface of the pin for constraining the printed circuit board between the first constraining part and the plastic frame. The liquid crystal panel is held by the plastic frame and electrically connected to the printed circuit board.

Abstract: A portable electronic device includes a housing and a chip card holder. The chip card holder includes a base fixed to the housing, a drawer slidably fixed to the base. The drawer includes at least two stacked receiving grooves, each receiving groove receives one of the chip cards.

Abstract: A method for locally forming a smooth surface on frosted glass includes steps of: a) preparing a piece of frosted glass; b) locally coating the frosted glass with a sealant; and c) such forming the sealant that has a smooth surface. The smooth surface of the frosted glass allows a video camera to capture clear images therethrough so as to prevent blurred images caused by micro-roughness on a surface of the frosted glass.

Abstract: The present technology discloses a switching mode power supply with predicted PWM control. In one embodiment, the switching mode power supply monitors the slew rate of COMP signal which represents the output voltage of the switching mode power supply. When the load steps up, the ON state of the power stage is prolonged; when the load steps down, the power stage is turned off earlier.

Abstract: A sliding mechanism for portable electronic device includes a sliding housing, a main housing and a stopping module. The sliding housing includes two ledges. At least one of the ledges defines a first notch and a second notch. The main housing includes two rails and at least one elastic member. The sliding housing is slidingly attached to the main housing by engagement of the ledges and the rails. The at least one elastic member includes a positioning portion. The positioning portion flexibly resists the at least one of the ledges and is selectively engaged in the first notch and the second notch. The stopping module prevents the sliding housing from separating from the main housing.

Abstract: In one aspect of the present invention, an LCD includes a front frame having a flange and a rear cover having a flange defining a housing therebetween, a liquid crystal (LC) panel placed in the housing, a backlight positioned between the LC panel and the rear cover, and a backlight frame having a first engaging structure configured to receive the flanges of the front frame and the rear cover, and a second engaging structure configured to retain the backlight and the LC panel in the housing.
