Abstract: A focusing module for scanners includes a body which holds a lens and a transmission device on one side thereof to move the lens linearly and adjust a desired scanning focal length. Therefore the diaphragm may be enlarged to increase the scanning speed without reducing the depth of field and dropping Modulation Transfer Function, and to achieve a faster scanning speed and a desired scanning quality.

Abstract: An LED light engine comprising a high thermal conductivity substrate (e.g., a metal-clad PCB), a plurality of light-emitting-diode (LED) semiconductor devices mechanically connected to the substrate, an outer dike fixed to the substrate and surrounding at least a portion of the LED devices, and a substantially transparent polymeric encapsulant (e.g., optical-grade silicone) disposed on the plurality of LED devices and restrained by said outer dike. In one embodiment, the light engine includes a reflector (e.g., a generally conic reflector) fixed to the substrate to form the outer dike. In another embodiment, an optical component (e.g., a lens, filter, or the like) is optically coupled to the polymeric encapsulant disposed on the LED devices.

Abstract: An apparatus for reducing start-up time uses an auxiliary light source and method for the same are proposed. The auxiliary light source has relatively short start-up time to compensate a cold cathode fluorescent lamp (CCFL) with long start-up time. The auxiliary light source is a light emitting device and simultaneously turned on with the CCFL. The light-emitting device is turned off when the output light of the CCFL is stable. Therefore, the light-emitting device with the CCFL can provide stable light source for scanner.

Abstract: A heat transfer system is presented for managing thermal transients, thus providing engineers greater flexibility in designing thermal solutions for applications subject to transient heat-generation. A heat reservoir device for managing a heat input subject to transient conditions includes a heat transfer subsystem having a first end and a second end, where the first end is thermally coupled to the heat input; a heat storage subsystem coupled to the second end of the heat transfer subsystem, where the heat storage subsystem comprises a phase change material responsive to the transient conditions. The excess heat load during transient operation is temporarily absorbed by the latent heat of fusion when the phase change material changes its phase from solid to liquid. Subsequently, the absorbed heat can be released back to the ambient via a heat rejection subsystem. This allows engineers to design smaller heat sinks capable of accommodating given transient conditions.

Abstract: A carriage used in image scanning devices includes an optical device installed on the beam path of an illuminating unit, producing a first projection beam and a second projection beam. A first projection unit and a second projection unit are used to transmit the two projection beams to a document to be scanned. An image capture unit is employed to receive the reflective beam from the document and generate image data. Since a single illuminating unit can provide two beams, the invention has the advantage of a simple structure and a low production cost.

Abstract: The present invention provides a method and system for selecting an access network in a heterogeneous network environment. The method records user configuration information in a mobile device and applies the mobile device to first collect and record current status information of each access network, then determines a network stability coefficient for each access network based on both the user configuration information and the current status information, and finally selects an access network with a maximum network stability coefficient to thus establish a connection with the access network selected.

Abstract: A contact image sensor module has a light source, at least one reflective element and a photoelectric conversion element. The photoelectric conversion element is arranged between the light source and the reflective element, such that the light from the light source is directed toward the manuscript. The reflective element receives the light reflected from the manuscript, and then the light is reflected back to the manuscript. The photoelectric conversion element receives light directed from the light source and the reflective element toward the manuscript, and then the light is converted into an electric signal, thus eliminating the dark band problem of the manuscript.

Abstract: A heat sink vacuum packaging procedure to rapidly complete the packaging of a heat sink without drilling, pipe welding, vacuum pumping, or other processes. Because the packaging procedure saves much time and labor, the manufacturing cost of the heat sink is relatively reduced. During packaging, no welding process is employed, therefore the invention prevents accidentally flowing of tin solder into the inside of the heat sink to affect the quality of the heat sink, and the quality of the heat sink is maintained.

Abstract: An LED lighting device for use in place of a commercial-standard light bulb. For example, a commercial-standard light bulb typically has an outer surface profile, generally defining its shape and the LED lighting device has its own surface profile which substantially mimics the surface profile of the commercial-standard light bulb. Additionally, LED lighting device may further comprise a heat sink for dissipating energy generated by the LED lighting device. In accordance with various embodiments, the heat sink creates the LED lighting device's outer surface profile and is configured to substantially mimic the outer surface profile of the commercial-standard light bulb.

Abstract: A photoresist dispense pump receives photoresist from two pipelines, a first pipeline and a second pipeline, and pumps out the photoresist through a third pipeline. The photoresist dispense pump contains a first bellows and a second bellows receiving photoresist from the second pipeline, wherein the first bellows and the second bellows are separated by a partition. Photoresist is fed into the third pipeline from the second bellows. On the center region of the partition, there is a central diaphragm that allows photoresist to flow in a direction from the first bellows toward the second bellows, but not in the reverse direction.
