Formulations, OLEDs, and consumer products containing the compound are also provided.

Abstract: A thermal processing apparatus and method in which a first laser source, for example, a CO2 emitting at 10.6 ?m is focused onto a silicon wafer as a line beam and a second laser source, for example, a GaAs laser bar emitting at 808 nm is focused onto the wafer as a larger beam surrounding the line beam. The two beams are scanned in synchronism in the direction of the narrow dimension of the line beam to create a narrow heating pulse from the line beam when activated by the larger beam. The energy of GaAs radiation is greater than the silicon bandgap energy and creates free carriers. The energy of the CO2 radiation is less than the silicon bandgap energy so silicon is otherwise transparent to it, but the long wavelength radiation is absorbed by the free carriers.

Abstract: A collapsible luggage includes a rigid base, a plurality of wheel members, a flexible body, and a telescopic rod unit. The rigid base defines a receiving space. The flexible body includes two side segments and opposite front and rear segments. The telescopic rod unit is disposed on one of the side segments of the flexible body, and is pivotable relative to the base between an unfolded position, where the flexible body is expanded so that the flexible body and the base cooperatively define an accommodating space, and a folded position, where the flexible body is collapsed, and the telescopic rod unit and the flexible body are received in the receiving space.

Abstract: A hand truck includes a support base, a plurality of wheels connected rotatably to the support base, a handle unit connected to the support base, and a fork unit. The support base has a pair of holding portions and a recess portion disposed between the holding portions. The fork unit has a pivoting portion connected pivotally to the support base, an inserting portion opposite to the pivoting portion, and a connecting portion interconnecting the pivoting portion and the inserting portion. The fork unit is pivotable between a retracted position, where the inserting portion and the connecting portion are adjacent to the support base, and a projected position, where the inserting portion and the connecting portion are away from the support base.

Abstract: A luggage includes a suitcase body, a plurality of wheels rotatably disposed under the suitcase body, and a pivotable telescopic pull handle unit disposed on the suitcase body. The pivotable telescopic pull handle unit includes a pair of fixation seats, a pair of pivoting seats, a pair of pivotable engaging units, a pair of telescopic rod units, a pair of telescopic engaging units, and an operating unit. Since rotation of said pivoting seats is driven by the pivotable engaging units, and since rotation of the telescopic rod units is driven by the telescopic engaging units, the luggage can be conveniently operated.

Abstract: A wheeled luggage includes a suitcase body with a container part which confines an interior space with a top opening. Atop cover is connected to a rear panel of the container part for covering and uncovering the top opening. A front panel of the container part is formed with a front opening, and includes a front cover for covering and uncovering the front opening. A bag is disposed removably in the interior space and has an upper edge portion which is foldable outwardly on an upper edge of the container part when the top cover uncovers the top opening.

Abstract: A garment hanger includes: a neck part having upper and lower ends and opposite first and second ends extending between the upper and lower ends; a hook extending from the neck part; a first shoulder adapted to support one of shoulders of a garment; and a second shoulder bar mounted movably on the neck part and adapted to support the other of the shoulders of the garment. The first and second shoulder bars diverge from the neck part in a first direction when the second shoulder bar is disposed at an extended position, and diverge from the first end of the neck part in a second direction different from the first direction when the second shoulder bar is disposed at a retracted position.

Abstract: An ergonomic wheeled baggage case includes top and bottom sides, and front, rear, and left and right panels. A first distance between the front and rear panels is shorter than a second distance between the left and right panels. A set of front wheels and a set of rear wheels are attached respectively to front and rear ends of the bottom side, and have bottommost ends which are substantially coplanar on a plane. The bottom side is oblique to the plane so that the front end of the bottom side is higher than the rear end thereof, thereby shifting the center of gravity of the case body rearwardly. The front, rear, left and right panels are substantially perpendicular to the plane.

Abstract: A travel case formable into a wardrobe when opened includes a case body, and a pull rod. The case body has a set of rollers attached to a bottom end of the case body, a cover connected pivotally to the case body, and a hanger holder provided on the cover. The cover is movable between covering and opening positions. The pull rod is connected to the case body. The cover can be pivoted to the pull rod in the opening position. A retainer is provided for retaining the cover on the pull rod when the cover is pivoted to the pull rod.

Abstract: A luggage includes a case body provided with a guiding rail, a slider mounted slidably on the guiding rail, a coupling unit pivoted to the slider, a handle rod connected to the coupling unit, an abutting member having a protrusion and pivoted to the slider for movement between a first angular position, in which the protrusion is free of contact with the guiding rail, and a second angular position, in which the protrusion abuts against the guiding rail when the slider is disposed at a predetermined position and when the handle rod is disposed at an inclined position.
