  • Publication number: 20170090683
    Abstract: Methods and devices are disclosed for delaying screen-on notification broadcasting. In one embodiment, a method for delaying screen-on notification broadcasting in a device comprises: detecting a display screen wakeup event for a display screen of the device, when the display screen wakeup event is detected and a current interface is a lock screen interface, intercepting a screen-on notification information broadcasted by an operating system of the device to applications running on the device, and when switching of the display screen from the lock screen interface into an unlocked interface after unlocking by a user is detected, sending the intercepted notification information to the applications.

  • Publication number: 20170040735
    Abstract: A micro plug connector has an insulative housing, multiple terminals, an outer casing, a front shell and a circuit board. The outer casing covers the insulative housing and has a vertical positioning slot and two stop portions to vertically and horizontally hold the circuit board. Therefore, the circuit board is firmly fabricated in the micro plug connector without disassembling out of the outer casing due to pull of wires in a transmission cable or a power cable.

  • Publication number: 20170016769
    Abstract: The present invention provides a measurement system of real-time spatially-resolved spectrum and time-resolved spectrum and a measurement module thereof. The measurement system includes an excitation light and a measurement module. The excitation light excites a fluorescent sample and the measurement module receives and analyzes fluorescence emitted by the fluorescent sample. The measurement module includes a single-photon linear scanner and a linear CCD spectrometer. The single-photon linear scanner selectively intercepts a light beam component of a multi-wavelength light beam that has a predetermined wavelength to generate a single-wavelength time-resolved signal, wherein the multi-wavelength light beam is generated by splitting the fluorescence. The linear CCD spectrometer receives the multi-wavelength light beam and generates a spatially-resolved full-spectrum fluorescence signal.

  • Patent number: 9478587
    Abstract: An array structure for light emitting diodes (LEDs) uses a patterned metal layer buried beneath LED chips to electrically interconnect non-adjacent chips in series, such that each chip in the LED array can be adjacently surrounded by LED chips of different colors. Thus, when the emission from the LED array is projected to a spot in the far field, its color uniformity over the spot is enhanced. Methods are also described for fabricating the multi-layer circuit board for such an array. Top and bottom patterned metal layers are formed, separated by a patterned insulating layer, so that electrical connections may be made between the metal layers. This provides “vias” between the metal layers for creating “cross-under” electrical connections under the second insulation layer, such that spatially-separated LED chips can be interconnected into strings, while maintaining electrical isolation between LED chips of different colors.

  • Publication number: 20160276136
    Abstract: A modular plasma source assembly for use with a processing chamber is described. The assembly includes an RF hot electrode with an end dielectric and a sliding ground connection positioned adjacent the sides of the electrode. A seal foil connects the sliding ground connection to the housing to provide a grounded sliding ground connection separated from the hot electrode by the end dielectric. A coaxial feed line passes through a conduit into the RF hot electrode isolated from the processing environment so that the coaxial RF feed line is at atmospheric pressure while the plasma processing region is at reduced pressure.

  • Patent number: 9404181
    Abstract: A plasma enhanced atomic layer deposition (PEALD) system used to form thin films on substrates includes a plasma chamber, a processing chamber, two or more ring units and a control piece. The plasma chamber includes an outer and an inner quartz tubular units, whose central axes are aligned with each other. Therefore, plasma is held and concentrated in an annular space formed between the outer and outer quartz tubular units. Due to the first and second through holes, the plasma flow may be more evenly distributed on most of the surface of the substrate to form evenly distributed thin films and nano particles on the substrate. In addition, due to the alignment and misalignment between the first and second through holes, the plasma generated in the plasma chamber may be swiftly allowed or disallowed to enter to the processing chamber to prevent the precursor from forming a CVD.

  • Publication number: 20160185853
    Abstract: This application provides, inter alia, antibodies or antigen-binding fragments thereof, targeting cell surface GRP78 expressed on tumor cells, tumor endothelial cells, and tumor initiating cancer cells. These anti-GRP78 antibodies, or antigen-binding fragments thereof, have a high affinity for GRP78 and are less immunogenic compared to their unmodified parent antibodies in a given species, e.g., a human, and function to inhibit GRP78. Importantly, these isolated novel antibodies and antigen-binding fragments thereof, attenuate PI3K signaling and promote apoptosis in tumor cells, while leaving normal cells unaffected. The antibodies and antigen-binding fragments are useful for UPR-targeted cancer therapeutic treatments.
