Abstract: The present disclosure relates to utilizing a firmware configuration system to efficiently update a firmware profile configuration of computing devices (e.g., host devices in a datacenter). For example, the firmware configuration system facilitates updating the firmware profile configuration, such as for a Unified Extensible Firmware Interface (UEFI) profile and/or a Basic Input/Output System (BIOS), without needing to develop, deploy, and install a new BIOS. More specifically, the firmware configuration system updates (e.g., via a baseband management controller) firmware profile configurations by modifying a profile configuration table in flash memory (i.e., on an SPI flash-based chip) of a BIOS with a firmware profile configuration update patch and without affecting other parts of the BIOS.

The high-voltage semiconductor device structure further includes a conductor electrically connected to the drain region and extending over and across a periphery of the well region. In addition, the high-voltage semiconductor device structure includes a shielding element ring between the conductor and the semiconductor substrate. The shielding element ring extends over and across the periphery of the well region.

Abstract: An electric window cleaning device includes an operating portion and a wiping portion which are attracted to both sides of a glass of a window by magnets, and are free to move along the glass by virtue of balls. The wiping portion includes a power mechanism and a power supply device. The power mechanism includes an output shaft, a rotary disc and a duster removably fixed to the rotary disc. The power device includes a switch and a battery which are electrically connected to the power mechanism. When the power mechanism is turned on, the output shaft rotates the rotary disc and the duster to clean the outer surface of the glass, as an user moves the operating portion which is attracted to the inner surface of the glass, the wiping portion will also move along the outer surface of the glass to perform cleaning operation.
