An angle adjusting mechanism includes a base seat, a driving assembly, a guiding assembly and an adjusting member. The driving assembly is mounted on the base seat. The driving assembly includes a driving member, a screw rod rotated by the driving member and a screw nut sleeved on the screw rod. The driving member is mounted on the base seat. The screw nut engages with the screw rod and is capable of moving along an axial direction of the screw rod. The guiding assembly is mounted on the base seat and guides the screw nut. The adjusting member is sleeved on the guiding assembly and rotated by the screw nut to a predetermined angle.

In this invention, the first refraction groove and the second refraction groove, which are located on two opposite ends of the reflection lens, are set on the same central axis. The said lens features a translucent shell and is of a horn-shaped appearance. The horn or cone-shaped mouth points from the first refraction groove to the second refraction groove. The outer surface is designed to have multiple reflection sections. When the LED light source is positioned at or in the first refraction groove, the light emitted from LED is refracted by the first refraction groove and then is sent out from the cone mouth at the second refraction groove. Meanwhile, the light which gets through the translucent lens shell is refracted by the multi-section reflection surface and then is also projected from the cone mouth. The reflection surface lens in this invention integrates multiple functions within the one body including focusing, refraction and reflection, which allows uniform illumination and other desired illumination effects without the need for any reflective coating. It simplifies the processing technique of LED illumination systems and reduces processing costs.

A method (100) of fabricating an LED or the active regions of an LED and an LED (200). The method includes growing, depositing or otherwise providing a bottom cladding layer (208) of a selected semiconductor alloy with an adjusted bandgap provided by intentionally disordering the structure of the cladding layer (208). A first active layer (202) may be grown above the bottom cladding layer (208) wherein the first active layer (202) is fabricated of the same semiconductor alloy, with however, a partially ordered structure. The first active layer (202) will also be fabricated to include a selected n or p type doping. The method further includes growing a second active layer (204) above the first active layer (202) where the second active layer (204) Is fabricated from the same semiconductor alloy.
摘要:
Co-selected images are labeled based on a topic score that is a measure of relevance of the co-selected image to a first topic to which a reference image belongs. The first topic to which the reference image belongs is identified based on a reference label associated with the reference image. The co-selected images are images that are selected for presentation subsequent to selection of the reference image during a user session. The co-selected images are identified based on selection data for user sessions in which the reference image was selected for presentation. The topic score is generated based on a frequency of selection of the co-selected image. Image search results for a second topic can be filtered to remove images that are labeled as belonging to the first topic or the image search results can be reordered to adjust the presentation positions at which images are referenced based on the topic to which the images belong.
摘要:
According to one aspect, an electronic device for detecting an audio accessory. The electronic device includes an audio jack having at least two detection terminals. The detection terminals are spaced apart and positioned within a socket of the audio jack so when an audio plug of the accessory is inserted into the socket of the audio jack, the detection terminals will be shorted. The presence of a short between the detection terminals is indicative that the audio accessory is present.

The present invention provides a clock control circuit, driving circuit and liquid crystal display device. The clock control circuit includes internal clock module, signal receiving module, selection module, detection module and control module. The detection module determines whether an external input signal is valid clock signal; if so, the control module controls the selection module to select the external input signal for outputting; otherwise, select the internal clock signal for outputting. As such, the present invention avoids condition of abnormal displaying of the LCD when no external input signal is present so as to improve the displaying quality of the LCD.
摘要:
A decorative metal finish for a part with a non-conductive surface where the non-conductive surface is lightly roughened to improve its adherence capabilities. A thin metal layer is electrolessly deposited on the lightly roughened surface to provide a bright durable metal finish on the non-conductive surface. An translucent finish is deposited over the thin metal layer to provide protection for the metal finish.
