Abstract:
A backlit logo device includes an elongated light guiding member and two sources. The two light sources are arranged at opposite ends of the light guiding member. The light guiding member includes a display surface. The display surface includes a transparent logo so light from the light sources passes through the logo. The light guiding member further includes a light reflecting surface opposite to the display surface. The light reflecting surface includes a plurality of light diffusing portions formed in a middle portion of light reflecting surface. The light diffusing portions are configured to diffusely reflect the light from the light sources to the display surface.
Abstract:
Embodiments of the present invention disclose a method, an apparatus, and a system for data transmission. The method for data transmission includes: determining that data to be transmitted is control plane signaling related to a user equipment that camps on a relay node; and transmitting the data through a first user data bearer established between the relay node and a donor base station, where the first user data bearer provides integrity protection for the data. According to the embodiments of the present invention, when the control plane signaling related to the user equipment that camps on the relay node is transmitted between the relay node and the donor base station, integrity protection is provided for the control plane signaling, and therefore attacks such as the denial of a service attack are prevented.
Abstract:
A method for manufacturing a light emitting diode includes steps: providing a base having leads formed thereon; fixing a light emitting die on the leads; disposing a glass encapsulant on the base; co-firing the encapsulant with the base to fix them together. The base is made of silicon or ceramic. The encapsulant has a cover covering the light emitting die received in a groove of the base and a positioning plate fittingly engaging into the groove in one embodiment. The encapsulant has a cavity receiving the light emitting die to cover the light emitting die fixed on a top face of the base in another embodiment. Various mechanisms are used to protect the light emitting die during co-firing of the encapsulant and the base.

Abstract:
A light emitting diode package includes a metal thin film with a first surface and a second surface opposite to the first surface. The metal thin film further defines a first part and a second part electrically insulated from the first part. A light emitting diode die is formed on the first part of the metal thin film. The light emitting diode die includes a first electrode and a second electrode. The light emitting diode die is sealed within a glass encapsulation and the second surface of the metal thin film is exposed to the outside of the glass encapsulation for electrically connecting with an external power.

Abstract:
In a method for manufacturing a LED package, a substrate of the LED package is formed by thermally pressing at least one insulating plate over an electrode plate and then grinding the insulating plates to expose the electrode plate.
Abstract:
A method and apparatus for measuring target gas concentrations in an atmosphere. The method and apparatus emit in the atmosphere a laser beam tuned to a molecular absorption line of a target gas, receive a reflected signal affected by gas absorption of the target gas in the atmosphere, divide and direct the received signal into a first optical path and a second optical path including in one of the paths a correlation gas cell filled with a predetermined concentration of the target gas, detect transmitted signals through the first optical path and the second optical path, and calculate a target gas concentration by comparing a first signal transmitted through the first optical path to a second signal transmitted through the second optical path. The apparatus includes a laser source tunable to a specific molecular absorption line of a target gas and configured to emit in the atmosphere a laser beam having a spectral bandwidth greater than a full width of the molecular absorption line of the target gas, a receiver configured to receive a reflected signal affected by gas absorption of the target gas in the atmosphere, and at least one detector configured to detect transmitted signals through the first optical path and the second optical path.
