  • Publication number: 20190087045
    Abstract: An uninterrupted learning uses a touch screen display device when connections to networks are unavailable or unstable. The touch screen display device is equipped with short range and long range communication capabilities in addition of capable being a WiFi hotspot. The touch screen display device incorporates the features of both the adaptive server and the teacher device. The adaptive server feature in the touch screen display device can communicate with a remote server through a local area network and switch to a cellular telecommunication network when the local area network is unavailable. The adaptive server can also act as the WiFi base station and accept connections from nearby student devices.

  • Publication number: 20190019899
    Abstract: Lateral and vertical microstructure enhanced photodetectors and avalanche photodetectors are monolithically integrated with CMOS/BiCMOS ASICs and can also be integrated with laser devices using fluidic assembly techniques. Photodetectors can be configured in a vertical PIN arrangement or lateral metal-semiconductor-metal arrangement where electrodes are in an inter-digitated pattern. Microstructures, such as holes and protrusions, can improve quantum efficiency in silicon, germanium and III-V materials and can also reduce avalanche voltages for avalanche photodiodes. Applications include optical communications within and between datacenters, telecommunications, LIDAR, and free space data communication.

  • Publication number: 20180375021
    Abstract: Resistive RAM (RRAM) devices having increased reliability and related manufacturing methods are described. Greater reliability of RRAM cells over time can be achieved by avoiding direct contact of metal electrodes with the device switching layer. The contact can be avoided by cladding the switching layer in a material such as silicon or using electrodes that may contain metal but have regions that are adjacent the switching layer and lack free metal ions except for possible trace amounts.

  • Publication number: 20180269973
    Abstract: Examples include generating a signal using a modulatable source. The signal may be propagated using a multi-mode fiber to receive the signal from the modulatable source. The fiber has a diameter d and a far-field divergence angle associated with the propagated signal that corresponds to a product of the diameter (d) and the far-field divergence angle. The product may be substantially between 1 micron radian and 4 micron radian. In some examples, the propagated signal may be received at a receiver from the multi-mode fiber.

  • Patent number: 9978939
    Abstract: Resistive RAM (RRAM) devices having increased uniformity and related manufacturing methods are described. Greater uniformity of performance across an entire chip that includes larger numbers of RRAM cells can be achieved by uniformly creating enhanced channels in the switching layers through the use of radiation damage. The radiation, according to various described embodiments, can be in the form of ions, electromagnetic photons, neutral particles, electrons, and ultrasound.

  • Patent number: 9960636
    Abstract: A DC converter includes a non-isolated conversion module and an isolated conversion module. The non-isolated conversion module is implemented based on a redundant structure and has a first power conversion loop, a second power conversion loop, and an energy storage element. The first and second power conversion loops are connected and share the energy storage element. The energy storage element is further connected to an input terminal of the isolated conversion module. The first and second conversion loops of the non-isolated conversion module convert DC power outputted from two battery sets and output the converted power to the isolated conversion module. The isolated conversion module further supplies DC power to a load. Accordingly, power supply systems using the foregoing DC converter can reduce the number of transformer therein and thus size reduction of the power supply system can be achieved.

  • Patent number: 9869836
    Abstract: Various embodiments of the present invention are directed to optical interconnects. In one embodiment of the present invention, an optical interconnect comprises a laser configured to output an optical signal and a laser-diode driver electronically coupled to the laser. The laser-diode driver induces the laser to output the optical signal in response to an electrical signal received by the laser-diode driver. The optical interconnect includes a diffractive optical element and a plurality of photodetectors. The optical interconnect is positioned to receive the optical signal and configured to split the optical signal into a plurality of optical signals, and each photodetector converts one of the plurality of optical signals into an electrical signal that is output on a separate signal line.

  • Patent number: 9818893
    Abstract: Techniques for enhancing the absorption of photons in semiconductors with the use of microstructures are described. The microstructures, such as holes, effectively increase the absorption of the photons. Using microstructures for absorption enhancement for silicon photodiodes and silicon avalanche photodiodes can result in bandwidths in excess of 10 Gb/s at photons with wavelengths of 850 nm, and with quantum efficiencies of approximately 90% or more. Their thickness dimensions allow them to be conveniently integrated on the same Si chip with CMOS, BiCMOS, and other electronics, with resulting packaging benefits and reduced capacitance and thus higher speeds.
