  • Patent number: 10481901
    Abstract: Systems and methods for performing firmware update on an embedded system by patching. In operation, a computing device may receive an image of replacement firmware, which is a different version of current firmware stored in a non-volatile memory of the embedded system. The computing device then determines the different portions of the replacement firmware from the current firmware by comparing the image of the replacement firmware to the current firmware, and retrieves the different portions from the image of the replacement firmware to form the fragments. In this case, the computing device may create a patch file by data of the fragments, and send the patch file to the embedded system, such that the embedded system may use the patch file to update the current firmware. The size of the patch file would be relatively smaller than the firmware image, thereby reducing update time and resources consumption.

  • Patent number: 10444810
    Abstract: Systems and methods for automatic power control and unusual activity detections for thin client computing devices. In operation, the server receives messages from the thin clients, with each message corresponding to a activity occurred at the thin clients. The server then analyzes the messages and generates usage patterns of the thin client computing devices. Based on the usage patterns, the server may generate automatic power control schedules for the computing devices, and control power of each of the computing devices based on the automatic power control schedules. Further, the server may monitor unusual activities occurred at the computing devices based on the messages and the usage patterns of the computing devices.

  • Patent number: 10234710
    Abstract: An electro-optic device having at least one liquid crystal cell for providing spatially variable control of light includes: a pair of opposed substrates sandwiching a liquid crystal layer therebetween; a pair of electrodes for applying an electric field therebetween, each electrode being deposited on a corresponding substrate; and a liquid crystal reservoir wall defining a lateral extent of the liquid crystal layer between the substrates. The reservoir wall includes: a first bottom barrier deposited on a bottom one of the pair of substrates; and a second curable top barrier deposited on the top substrate outside the first barrier. The first barrier and second uncured barrier are configured to merge on contact to retain liquid crystal material inside the reservoir wall prior to curing the second barrier. Also, a method of wafer level manufacturing and assembly of a liquid crystal optical device.
