Abstract: Solutions for managing RAID virtual disks. Some solutions enable increased use of hardware circuitry to schedule and perform IO on a virtual drive, providing for more efficient IO. In some cases, this can be accomplished by notifying the hardware of precise regions of a virtual disk affected by the maintenance operation and any given time. The hardware then, can continue to perform host IO on portions of the logical disk not undergoing maintenance.

Abstract: A memory system includes a firmware unit and a cache module that includes a cache controller and a cache memory. The cache controller receives an I/O message that includes a local message ID (LMID) and data to be written to a logical drive (LD), stores the data in a cache segment (CS) row of the cache memory and sends an ID of the CS row to the firmware unit. The firmware unit, in response to receiving the ID of the CS row, acquires a timestamp and stores the timestamp to check against a cache flush timeout for the CS row. The firmware unit periodically checks cache flush timeout and in response to detecting the cache flush timeout, sends a flush command with the ID of the CS row to the cache controller. The cache controller, in response to receiving the flush command, flushes the first data of the CS row.

Abstract: This application is directed to a method for correct temperature measurement. An electronic device includes a temperature sensor that measures an ambient temperature of an environment and a display that is driven by a display driver. The electronic device determines a brightness setting of the display, estimates a display driver current based on the brightness setting, estimates a driver efficiency of the display driver based on the display driver current, and combines a predetermined display driver voltage, the display driver current, and the driver efficiency to determine a power consumption of the display driver.

Abstract: The present document describes techniques for safe battery charging during high ambient temperatures. These techniques extend device runtime during peak use periods when ambient temperature is high by increasing the possibility for battery charging during high ambient temperature conditions. In an example, a device, during high ambient temperatures, checks future ambient temperatures over a network to identify if the minimum future ambient temperature over a block of time within the next N number of days is predicted to be sufficiently low that, when combined with device-performance throttling, is estimated to reduce the temperature of the battery to below the maximum charge temperature to enable the battery to be safely charged. The device can also use the future ambient temperatures to budget current battery usage by implementing and/or adjusting device-performance throttling.
