Abstract:
The subject invention relates to a semiconductor package and method of manufacturing the same. The semiconductor package of the subject invention comprises a substrate with a through hole penetrating therethrough; a semiconductor chip positioned on the substrate covering the through hole; and a thermal conductive device filling the through hole and contacting the semiconductor chip. According to the subject invention, the thermal resistance in the structure of the semiconductor package is substantially reduced and thus desirable performance of heat spreading or dissipation is achieved. In addition, the production cost and size of the semiconductor package are also reduced.
Abstract:
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.
Abstract:
A remote-controllable lighting device comprising a first substrate and an adjacent second substrate maintained in a spaced apart relationship to allow airflow therebetween and at least partly overlapping each other, at least the second substrates carrying thereon at least one emission sources, the first substrate being located towards a proximal end of the device and the second substrate being located towards a distal end of the device; said first substrate being arranged so as to allow light generated by the at least one located second light emission source to pass thereby in a direction defining a primary light emission direction and said first light emission source located so as to emit light in said primary light emission direction; said first and second substrate being in thermal communication so as to allow heat generated by the at least one light emission sources to flow between the substrates so as to provide thermal distribution between the substrates, the first and second substrate being formed of a thermally conductive material suitable for convection of the generated heat therefrom; a signal detector for receiving a wirelessly transmitted control signal from a remote control device; said signal receiver being located proximal of the first substrate in the primary light emission direction; and a controller in communication with said signal detector and the light emission sources and for controlling at least one characteristic of at least one light emission source responsive to said control signal.
Abstract:
A positioning method for a sensor node is provided, and the method includes steps of: providing a first antenna having a first omnidirectional radiation pattern on a first plane; rotating the first antenna about an axis substantially parallel to the first plane; transmitting a wireless signal while the first antenna rotates about the axis for every a predetermined central angle; receiving the wireless signal at the sensor node; obtaining Received Signal Strength Indications (RSSIs) of the respective wireless signals; and determining a location of the sensor node according to the RSSIs.
Abstract:
A light emitting device with a remotely located light scattering material which improves color mixing property is provided. The light emitting device includes a substrate defining a cavity; one or more light emitting elements bonded to the substrate and positioned in the cavity; at least one first layer covering the one or more light emitting elements, at least part of the at least one first layer within the cavity, wherein the at least one first layer has a refractive index less than the refractive index of the one or more light emitting elements; and at least one second layer including light scattering material disposed on the at least one first layer, wherein the refractive index of the first layer is less than or equal to the refractive index of the second layer.

A heat-dissipating reflector for a lighting device having a reflecting surface for reflecting light from a light emitting source of the lighting device, and a plurality of ventilation openings formed through the reflecting surface for dissipating heat generated by the light emitting source.
Abstract:
A transducer array includes two or more sub-arrays that move relative to each other. Position sensors on each of the sub-arrays provide spatial coordination for beamforming and/or image forming to yield extended field of view and high image resolution. The adaptable transducer array, such as mounted on a flexible transducer housing, allows the array to better conform to the patient during internal or external use.
Abstract:
An EPD device includes a plurality of pixels, wherein a first pixel is written by a first grey level, a second pixel is written by a second grey level. When the EPD device refreshes the displayed frame, the first pixel and the second pixel are erased individually. After the erasing of first pixel is completed, a third grey level is written to the first pixel immediately. After erasing of the second pixel is completed, a fourth grey level is written to the second pixel immediately. Thus, each pixel is written by their next grey levels immediately after the erasing step so the writing time is reduced and the motion blur of the EPD device when refreshing the displayed frame can be improved.
Abstract:
The present invention relates to topical compositions containing fermented extracts of Traditional Chinese Medicinal (TCM) ingredients for improving the appearance and skin condition of the user. The topical compositions of the present invention are tailored for different users of different skin compositions according to TCM principles. The fermented TCM extracts are characterized by reduced odor and/or color in comparison with unfermented TCM extracts and are therefore more suitable for use in cosmetic products.
Abstract:
The expression of Her-2/neu protein on circulating cancer cells in a sample of blood or peripheral blood mononuclear cells (PBMCs) is detected by performing a sensitive Her-2/neu immunoassay. There is no need to isolate the cancer cells before performing the immunoassay. A positive result indicates the expression of Her-2/neu on cancer cells in the blood sample. This method can be used to identify cancer patients who are likely to benefit from treatment with an anticancer agent that targets Her-2/neu, such as trastuzumab (HERCEPTIN), lapatinib, CP-724,714, NKI-272, and BMS-599626
