摘要:
An alumina substrate and method of making an alumina substrate using oxidation is provided. Generally, photoresist masks are used to protect selected areas of an aluminum layer. The unprotected or exposed areas of the aluminum layer are then oxidized during a photolithography process. The protected, unexposed areas of the aluminum layer retain their conductive properties while the oxidized areas are converted to alumina, or aluminum oxide, which is non-conductive. Accordingly, an alumina substrate having conductive areas of aluminum is formed. In one embodiment, the alumina substrate includes an alumina layer, one or more aluminum vias formed within the alumina layer, each of the one or more aluminum vias extending between the bottom of the alumina layer and the top of the alumina layer, wherein the one or more aluminum vias are integrally formed within the alumina layer.

A lighting control system for controlling the lighting of a predetermined area is provided. According to one embodiment, the lighting control system comprises one or more light sources positioned in the predetermined area, the light source configured to include adjustable light intensity; a camera positioned and configured to capture an image of the predetermined area; and a controller in operable communication with the one or more light sources and the camera, the controller configured to control the one or more light sources and adjust the light intensity of the light source. The controller is configured to operate in a closed control loop to automatically adjust the lighting conditions of a predetermined area or environment. A false alarm checking process checks for temporary or localized events to prevent unnecessary lighting adjustments.

A plurality of disc-shaped substrates carry light emitters and are axially stacked, spaced apart, in a metal housing to dissipate the heat produced by the light emitters. The housing comprises mutually connected elongate planar ribs that abut the light emitters or substrates for thermally connecting the light emitters to the housing. The ribs have shoulders. The substrates are received between the ribs and abut the shoulders. The shoulders are positioned proximate each light emitter in intimate contact with the substrate for efficient heat dissipation.

A lighting device contains a plurality of light emitting sources mounted on a thermally conductive housing and electrically connected to a circuit board. The housing includes a base portion which is spaced apart from the circuit board, and an intermediate heat dissipation structure which is disposed between the circuit board and the base portion of the housing, for promoting cooling by convection. The plurality of light emitting sources are in thermal communication with the intermediate heat dissipation structure.

A light emitting device includes a first light emitting diode (LED) emitting a first light emission of at least a first wavelength, and a second light emitting diode emitting a second light emission of at least a second wavelength. The second LED is placed in close proximity to the first LED such that after a mixing length from the first and second LEDs, a combination of the first and second lights is perceived as one color in the human vision. In use, the first and second LEDs are alternately driven by a power source in the time domain.

A microcavity structure. In an illustrative embodiment, the microcavity structure includes a first substrate, which has a region of interest. A second substrate with a perforation therein is bonded to the first substrate. The perforation coincides with the region of interest. In a specific embodiment, the first substrate is implemented via a Printed Circuit Board (PCB). The region of interest includes one or more circuit components, including an actuator, such as a bridgewire, thereon or therein. A smoothing layer is included between the PCB and the actuator. A bonding gasket adheres the first substrate to the second substrate. The perforation accommodates energetic material that is selectively ignited via the actuator.

A method of tracing data on a network for a Web request that detects events of the Web request as the Web request is serviced. The method provides a unique identifier (ID) for the Web request. The ID is associated with all events for the Web request in a trace log. When such events occur in the servicing of the Web request, each event is recorded with the ID of the Web request in a trace log. The trace log can be accessed via the ID to debug a Web request service failure.
