Abstract: Systems and methods for flash memory conflict avoidance cause a firmware over the air (FOTA) update to be given priority over a scrubbing operation unless the memory element meets or exceeds a predefined health degradation parameter. When the memory element meets or exceeds the predefined health degradation parameter, the scrubbing operation is given priority over the FOTA update. By enforcing these priorities, scrubbing and FOTA updates do not occur at the same time and conflicts are thereby avoided. Since conflicts are avoided, the chance of memory corruption is decreased and the chance of “bricking” the computing device is likewise decreased.

Abstract: In a conventional system with a UFS storage device connected to a UFS host over one or more lanes, the lanes can support different transmission speeds, referred to as gears. The UFS host shifts lanes and gears based on the type of request it receives. When the requests arrive in random order of gear requirements, the frequent shifting of the lanes and gears causes significant power consumption. To address this issue, it is proposed to implement a queue-based shifting in which arriving requests may be queued based on their gear requirements. When a queue is selected, multiple requests in the selected queue, which are all of same or similar gear requirement, can be served. This can reduce the frequency of gear shifting, and hence reduce power consumption.

The method includes capturing the image at the first luminance level when the brightness level satisfies the threshold. The method includes detecting a face in the image. The method includes determining if the face corresponds to an authorized user. The method includes unlocking the electronic device when the face corresponds to an authorized user.

Abstract: Systems, methods, and apparatus for rewriting or adjusting a TCP timestamp value are described. The methodology includes determining network conditions of a wireless network, and establishing a transmission control protocol (TCP) connection between a first communication device and a second communication device via the wireless network. The timestamp value within a TCP packet to be transmitted, such as as a TCP SYN ACK packet in a 3-way handshake, is adjusted with the use of a timestamp adjusting circuitry or hardware, where the adjustment is based on the determined network conditions. By adjusting the timestamp of a TCP packet prior to transmission and based on network conditions, unnecessary retransmissions are reduced. Additionally, the use of timestamp adjusting hardware allows for more efficient timestamp adjustment by offloading processor computations.

Abstract: An embodiment is directed to an apparatus that comprises a host controller and a flash memory. The host controller monitors a temperature in a first memory block of the flash memory (e.g., based on a reported temperature measurements from the flash memory), and selectively synchronizes a first refresh of the first memory block with a second refresh of a second memory block of the flash memory based in part upon the monitored temperature. For example, an immediate refresh of the first memory block may be performed if there is a pending I/O request for the first memory block, an error rate associated with the first memory block exceeds an error rate threshold and/or the monitored temperature of the first memory block exceeds a temperature threshold; otherwise, a synchronized refresh of the first and second memory blocks may be executed.
