    摘要： Systems and methods are disclosed for multi-coil wireless power transfer. The system includes a first transmitting coil disposed within a lower portion of a wireless charger, and a second transmitting coil disposed within a side portion of the wireless charger. The system further includes a communications module configured to receive a signal from an information handling system. The information handling system includes a receiving coil. The system additionally includes a transmit module configured to determine an orientation of the receiving coil, and provide a first current to the first transmitting coil and a second current to the second transmitting coil based on the orientation of the receiving coil.

    摘要： A solid-state drive (SSD) may not include a dynamic random access memory (DRAM) but rather may utilize a host memory buffer of system random access memory (RAM). During a power failure data on dirty cache lines may be lost. A power protection caching policy may be implemented where an SSD controller is capable of accepting a flush cache signal, which may be a signal to a redefined pin of the SSD or a command, from a controller of the information handling system. The controller may utilize a slope detect mechanism and/or a power good detect mechanism to detect a power failure and if a power failure is detected to issue a flush cache signal the SSD controller to cause a flush of all dirty cache lines from the host memory buffer before the power failure results in inoperability of circuitry associated with the dirty cache lines.
