In some aspects, the present disclosure provides a method for managing data communication rates of a memory device. The method includes receiving an input/output (I/O) operation to be performed by the memory device, detecting a temperature of the memory device, and determining whether the detected temperature satisfies a threshold condition. The threshold condition is satisfied if the detected temperature is above a first temperature threshold or below a second temperature threshold. If the threshold condition is satisfied, selecting a gear from a plurality of gears based on a ranking of the plurality of gears at the detected temperature, wherein each gear of the plurality of gears correspond to a respective one of a plurality of data rates used by the memory device for performing I/O operations, and serving, to the memory device, the I/O operation with an indication to perform the I/O operation using the selected gear.

Data rate shifting based on temperature

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.

Certain aspects of the present disclosure provide techniques for performing face recognition in low light conditions using an electronic device. One aspect provides a method including determining if a brightness level within a viewing area of the electronic device satisfies a threshold. The method includes increasing a luminance output of the electronic device from a first luminance level to a second luminance level when the brightness level does not satisfy the threshold. The method includes capturing an image at the second luminance level when the brightness level does not satisfy the threshold. 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.

A method of scheduling universal flash storage (UFS) operations using a refresh handover mechanism is described. The method includes receiving, during refresh of a UFS device, a request for an input/output (I/O) operation. The method also includes handing over between a first type of refresh operation and a second type of refresh operation in response to the request for the I/O operation.

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.

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.

Aspects include computing devices and methods implemented by computing devices for smart of handling input/output interrupts associated with device setting levels. Various aspects may include receiving a hardware input/output interrupt from a hardware interface, updating an adjusted feature setting level, determining whether the adjusted feature setting level equals a feature setting level limit, and changing an interrupt service routine address stored at a first location of a hardware input/output register corresponding with an interrupt service routine associated with the hardware input/output interrupt to a first data in response to determining that the adjusted feature setting level of the computing device equals the adjusted feature setting level limit.

Smart handling of input/output interrupts

Methods, devices, systems, and non-transitory process-readable storage media of the various embodiments enable a software-enabled access point mobile computing device to delegate prefixes to already connected local area network (LAN) client devices upon establishment or re-establishment of a data connection. The various embodiments may enable a mobile computing device configured to operate as a mobile router (i.e., a softAP mobile computing device) to support prefix delegation by providing unique IPv6 prefixes to connected LAN client devices.
