Abstract:
In some embodiments, an information handling system may include a motherboard including a processor and memory coupled to the processor; one or more power supply units configured to provide power to the motherboard; and a connection system configured to deliver voltage from the one or more power supply units to the motherboard in both: (a) a first configuration including a single power supply unit providing power to the motherboard; and (b) a second configuration including multiple power supply units providing power to the motherboard.
Abstract:
A pointing-stick structure for input device includes: a print circuit board, a light-emitting device, a stick, and a cap. The light-emitting device electrically connects to the print circuit board. The stick receives the light-emitting device and is connected the print circuit board, and the cap covers the top of the stick. The light emitted from the light-emitting device projects through the cap.
Abstract:
A double-deck connector assembly (1) includes a unitary housing (10) defining upper and lower connection ports (12, 14) with upper and lower central slots (16, 17) for respectively receiving the corresponding upper and lower modules (100, 200) therein. The upper connection port (12) is slightly forwardly offset from the lower connection port (14). A pair of latching arms (20, 22) extend from two opposite ends of each connection port (12, 14) for retaining the corresponding module (100, 200) in position. A latching lug (28, 34) is formed on each latching arm (20, 22) for locking the module (100, 200) in position. A guidance surface (85) is formed around a lower portion of the upper latch arm (20) so that the upwardly rotated lower module (200) can guidably move along the guidance surface (85) to outwardly push away the corresponding upper latch arm (20) thereabove to reach the initial insertion angular position which is essentially above the upper latch arm (20).
Abstract:
Disclosed is a light-emitting device comprising: a semiconductor stack layer; a reflective layer on the semiconductor stack layer; a first buffer layer comprising a compound comprising a metallic element and a non-metallic element on the reflective layer; a first electrode; and an electrical insulating layer disposed between the first buffer layer and the first electrode.
Abstract:
A keyboard. The keyboard comprises at least one key, a base, a membrane assembly and a circuit board. The membrane assembly is disposed between the base and the key. At least part of the circuit board is disposed in the key. The keyboard is connected to a notebook computer or a personal computer via a connection member.
Abstract:
A light module having a first power line, a second power line, and light devices. The first power line is connected to a first power point. The second power line is connected to a second power point. Each light device having a first terminal coupled to the first power line and a second terminal coupled to the second power line. A first sum of a first line length between the first power point and the first terminal of any of the light devices and a second line length between the second power point and the second terminal thereof is substantially a first constant.

Abstract:
An electrical connector includes an insulative housing defining a mating cavity, a tongue portion forwards extending into the mating cavity and defining thereon first and second faces opposite to each other, and first and second sets of contacts retained to the housing. The first set of contacts includes pairs of differential pairs and grounding contacts arranged at opposite sides of the differential pairs, and each of the differential pairs defines a first contacting section disposed in the first face and a soldering section. The second set of contacts each defines a deflectable cantilevered beam accessible from the second face. At least one of the grounding contacts defines a main section retained in the tongue portion and further extending into the mating cavity along the tongue portion, and the main section is disposed in a plane perpendicular to the first face.
Abstract:
An electrical connector includes an insulative housing defining a mating cavity, two parallel and stacked mating portions respectively forwards extending into the mating cavity, sets of contact retained in the housing and a grounding member retained in the housing. The first mating portion defines thereon a first surface; the second mating portion spaces from the first mating portion and defines thereon a second surface opposite to the first surface. The sets of contact include a first set of contacts each defining a contacting section exposed upon the first surface and a second set of contacts each defining a deflectable cantilevered beam accessible from the second face. The grounding member is disposed between the first and second mating portions to reduce the cross-talk between the first and second sets of contacts.
