  • Patent number: 11232109
    Abstract: The described implementations are operable to determine potential objects of interest to a user based on a blend of the user's long-term behavior and short-term interests. Long term user behavior may be determined for the user over a period of time and represented as continuous data. Short-term interest may be determined based on objects with which the user has recently interacted and attributes of those objects may be represented together as continuous data corresponding to the short-term user interest. The continuous data of the short-term interest and long-term user behavior may be blended to produce a user embedding. The user embedding may then be compared with objects to determine objects that are of potential interest to the user.

  • Publication number: 20220021881
    Abstract: A method includes encoding, by a encoder, a video frame of a versatile-video coding (VVC) video-compression system. The encoder generates/uses tile information associated with a video frame, determines for a slice that the slice is a subset or a superset of a tile based on the tile information, determines slice parameters associated with the slice, and signals the slice parameters associated with the slice. In other aspects, a method may include retrieving, by a decoder of a video-compression system, tile information associated with a video frame, determining, for a slice, that the slice is a subset or a superset of a tile based on the tile information, determining slice parameters associated with the slice, and decoding the video frame using the determined slice parameters.

  • Publication number: 20220019990
    Abstract: The electronic device may invoke a host application. The device may display a first host user interface on the display, the first host user interface including a first host user interface component associated with a child application. In response, the device may invoke, using the host application, the child application executed at the electronic device. The device may transmit, using the host application, a request for data associated with a child user interface component to the child application. The device may transmit, using the child application, the request for data associated with the child user interface component to a child application server, wherein the data associated with the child user interface component is inaccessible by the host application. The device may receive, using the child application, the data associated with the child user interface component from the child application server. The device may display the child user interface component.

  • Publication number: 20210397718
    Abstract: Systems, apparatuses, and methods for improving security of a silicon-based system by creating a glitch-resistant process for executing a software code block on the silicon-based system are disclosed. An example method may begin by marking the software code block as non-executable. Second, intent to execute the software code block is registered with a staging register. Third, the software code block is compressed into a compression constant. Fourth, the compression constant is compared with a first predetermined value using two comparators. Fifth, responsive to the comparators providing a true result after comparison, the software code block is marked as executable to allow the software code block to execute. In another aspect, the example method may be repeated for n>1 iterations, and in each iteration i, an ith software code block is compressed into an ith compression constant that is compared to an ith predetermined value.

  • Patent number: 10872154
    Abstract: A semiconductor chip device include device state fuses that may be used to configure various device states and corresponding security levels for the semiconductor chip as it transitions from wafer manufacturing to provisioned device. The device states and security levels prevent the semiconductor chip from being accessed and exploited, for example, during manufacturing testing. A secure boot flow process for a semiconductor chip over its lifecycle is also disclosed. The secure boot flow may start at the wafer manufacturing stage and continue on through the insertion of keys and firmware.

  • Patent number: 10728993
    Abstract: A driver circuit receiving wireless communication over a wireless network is disclosed. The driver circuit includes a lighting load, a main driver, and an auxiliary driver. The lighting load is selectively illuminated based on an output voltage being provided to the lighting load that is at least a forward voltage of the lighting load. The wireless communication is indicative of whether the lighting load is to be illuminated. The main driver is for controlling current and voltage within the driver circuit such that if the wireless communication indicates the lighting load is to be illuminated, then the current delivered to the lighting load is regulated by the main driver, and if the wireless communication indicates the lighting load is not to be illuminated, then the output voltage delivered to the lighting load is controlled by the main driver is below the forward voltage.

  • Patent number: 10261700
    Abstract: A method of accessing data in a non-volatile memory device is disclosed. The method includes serially receiving a command having an address in a virtual address space. When the address maps to the buffer in memory, the address may be matched to the address to one of a plurality of segments in buffer memory. Data may be moved from internal EEPROM/Flash memory to a segment of the plurality of segments of the buffer memory for an address range in the virtual address space that is likely to be read. A physical address may be generated within the buffer memory based on the address. Data may be fetched in the buffer memory based on the generated address and then a response for the command may be transmitted that includes the fetched data.
