Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: An assembly includes a second member and a latch. The second member has a through hole. The latch includes a hollow pillar and a bolt. The hollow pillar includes a first engaging portion and a second engaging portion opposite to each other. The hollow pillar has an inserting hole. The inserting hole passes through the first engaging portion and the second engaging portion. The first engaging portion is disposed through the through hole. The bolt is inserted into the inserting hole and is movable between a first inserting position and a second inserting position. When the bolt is moved to the second inserting position along a direction from the first engaging portion pointing to the second engaging portion, the second engaging portion is expanded by the bolt to make the size of the second engaging portion become larger.

Abstract: A slat fastening assembly, applicable to a circuit board, includes a slat, at least one first fastening member, a base, and at least one second fastening member. The first fastening member is disposed on the slat. The base is fixed on the circuit board. The second fastening member is disposed on the base. The first fastening member is detachably combined with the second fastening member, so that the slat is detachably combined with the base.

Abstract: An electronic device and a heat dissipation unit thereof are provided. The electronic device includes a housing, a circuit board, a heat source, a heat dissipation system and a heat dissipation unit. The circuit board is disposed in the housing and the heat source is disposed on the circuit board. The heat dissipation abuts the heat source, and the heat dissipation unit, disposed on the housing, abuts the heat dissipation system, wherein a portion of the heat dissipation unit is exposed outside of the housing. The heat dissipation unit includes a connecting portion, a heat exchanger, and a heat pipe. The connecting portion, disposed in the housing, abuts the heat dissipation system. The heat exchanger is disposed in the housing, and a portion of the heat exchanger is exposed outside of the housing. The heat pipe connects the connecting portion with the heat exchanger.

Abstract: The present invention relates to a method of medicine administration for respiratory tract and an apparatus for continuous medicine administration for respiratory tract. The present invention mainly utilize a respiratory tract medicine-administrated apparatus, which includes a medicine-storing chamber, which may be attached with an opening for filling in medicine, a medicine-administrated mechanism, which is connected to the medicine-storing chamber, and a medicine-exiting port, which is connected to the medicine-administrated mechanism. The medicine-administrated mechanism includes a pusher, an air intake, and a medicine-mixing chamber. In the most front end of the medicine-exiting port, there is an arrangement of nose-inserting portion of medicine-inhaling hole with opening shape. The interior of medicine-storing chamber may be filled with powder-like medicine, and a pusher with handgrip is inserted into one side portion of the medicine-storing chamber.

Abstract: A clipboard includes a backing board on which a clip member is mounted pivotally, a torsional spring unit arranged between the backing board and the clip member so as to bias one end of the clip member to abut against the backing board, and a whistle formed integrally with the clip member.

Abstract: A clipboard includes a board and a clip member. A recess is formed at the outside face of the clamp member and is configured to receive a calculator. A positioning device is provided for detachably positioning the calculator in the recess of the clamp member. Therefore, the calculator can be easily removed from the clamp member because a large working space is available.

Abstract: A clip board has an integrally formed elongated clip mounting member which has a groove means extending longitudinally therein. A U-shaped plate insert means is inserted in the groove means and opened upward. A bent rod has an engaging portion to engage with the board, two bent arm portions on two sides of the engaging portion, and two opposing end portions extending inwardly from the arm portions. The opposing end portions are received in the groove means with two coil springs respectively provided thereon. The coil springs have engaging portions which threads through the board and is bent to be engaged with the bottom side of the board. The upward extending portions of the insert means confines a channel above the coil springs to clamp therebetween releaseably a pen or the like.

Abstract: By modification of the design on the U-shaped bracket in previously awarded U.S. Pat. No. 4,628,572, the invention provided a renovated structure for a kind of hinge-typed clipboard which can also equally avoid to use rivets in assembly work. Its elements consist of a board, a supporting base, a clamping element, a torsional spring and a pivotal axle. The distinctive features are that the supporting base is made of metal plate with both sides bent upward and ends rolled up into tube shape. On the board, two transverse groove slots are provided to allow the tube-shaped element of supporting base penetrating through upward from the bottom of the board for combination with clamping element, spring and pivotal axle into an integral clipboard.

Abstract: An improved clip for clamping papers has a pair of generally T-shaped clamping members each having a clamping portion and two lugs, a pivot pin for interconnecting pivotally the lugs of the clamping members, and a torsion spring mounted on the pivot pin for biasing the clamping portions of the clamping members to abut against each other. The improvement wherein an end of the pivot pin has two axially spaced annular flanges between which the pivot pin passes through a lug of a clamping member and a lug of the other clamping member. The pair of lugs disposed between the flanges are biased by the torsion spring to move in opposite directions and in turn to clamp tightly the pivot pin between the flanges, thereby preventing one of the flanges from outward movement by the obstructing action of the lugs between the flanges.

Abstract: Since the utilization of U-shaped bracket of the present invention, the clipboard obviates the use of rivets in assembly, and the clamping bodies of a clip can be formed by injection molding. Therefore, the present invention simplifies the manufacturing process in making a clipboard or a clip, and provides the advantages of easily assembling and low cost.
