Abstract: An information handling system includes a plurality of persistent memory devices and a basic input/output system (BIOS). The BIOS begins a power-on self-test (POST) of the information handling system. During the POST, the BIOS may call a block input/output (I/O) driver to access a memory region within the first persistent memory device. The access of the memory region within the first persistent memory device is to determine whether the first persistent memory device is a bootable persistent memory device. The BIOS may determine whether blocks of the memory region contain bad memory locations. In response to the memory region containing bad memory locations, the BIOS may return a device error message without performing the access of the blocks of the memory region within the first persistent memory device and may boot to an operating system of the information handling system via another bootable device.

Abstract: An information handling system includes a non-volatile dual in-line memory module (NVDIMM) and a processor. The NVDIMM instantiates first and second partitions of non-volatile memory. The first partition is reserved and is not accessible to an operating system instantiated on the information handling system. The second partition is accessible to the operating system. The first partition includes a first region and a second region. The processor boots the information handling system to configure the NVDIMM based upon information from the first region, detects an error associated with the NVDIMM, and writes information associated with the error to the second region.

Abstract: A power tool includes a case, a motor, a plurality of Hall effect sensors, a first circuit board, and a second circuit board. The Hall effect sensors detect a position of a rotor of the motor and correspondingly generate position signals. A plurality of commutating switches and a first controller are disposed on the first circuit board. A second controller is disposed on the second circuit board, and could transmit a driving signal to the first controller according to the operating signal of an operator interface.

With such design, a commutation process and a user operating process are regulated by the two different controllers, which could efficiently simplify the program code installed in each of the controllers and facilitate the maintenance of the controllers.

Abstract: A memory scrubbing system includes a persistent memory device coupled to an operating system (OS) and a Basic Input/Output System (BIOS). During a boot process and prior to loading the OS, the BIOS retrieves a known memory location list that identifies known memory locations of uncorrectable errors in the persistent memory device and performs a partial memory scrubbing operation on the known memory locations. The BIOS adds any known memory locations that maintain an uncorrectable error to a memory scrub error list. The BIOS then initiates a full memory scrubbing operation on the persistent memory device, cause the OS to load and enter a runtime environment while the full memory scrubbing operation is being performed, and provides the memory scrub error list to the OS.

Abstract: A facial expression modeling method used in a facial expression modeling apparatus is provided that includes the steps outlined below. Two two-dimensional images of a facial expression retrieved by two image retrieving modules respectively are received. A deep learning process is performed on the two two-dimensional images to generate a disparity map.

The three-channel feature map is processed by a weighting calculation neural network to generate a plurality of blend-shape weightings. A three-dimensional facial expression is modeled according to the blend-shape weightings.
