Abstract: UEFI images can be securely loaded at runtime so that it is unnecessary to flash the entire platform firmware whenever a UEFI image is added or updated. The platform firmware can include an OEM file list that maps file GUIDs to public keys. When it is desired to add a UEFI image, the OEM can employ one of the file GUIDs in the OEM file list and a private key corresponding to the mapped public key to create the UEFI image. During the PEI phase of the boot process, a verification module in the platform firmware can verify any added UEFI image using the OEM file list. Additionally, to ensure that the added UEFI images will pass the subsequent Secure Boot verification, a sync module can add custom Secure Boot keys for the added UEFI images to the Secure Boot databases during the DXE phase of the boot process.

Abstract: The identification and loading of an appropriate service operating system can be facilitated when a main operating system fails. To facilitate the identification of which main operating system failed, an agent can create a UEFI variable that is specific to each main operating system on a client. These OS-specific UEFI variables can be employed to identify which main operating system has failed to boot. When a main operating system fails to boot, a UEFI preboot application can be configured to access the UEFI variables to identify which main operating system has failed. The UEFI preboot application can also obtain characteristics of the failed operating system from the UEFI variable and include such characteristics in a vendor extension of an SLP request. A server can employ the characteristics defined in the vendor extension to identify and send an appropriate service operating system to the client.

Abstract: A BIOS of an information may transmit information regarding events detected by the BIOS to an OS of an information handling system for logging in an OS event log. A BIOS of an information handling system may detect an event and may log information regarding the event in a memory of an information handling system. An OS of the information handling system may retrieve at least a portion of the information regarding the event from the event log and may add at least a portion of the retrieved information to an OS event viewer.

Abstract: An information handling system may load first data from a location information area of a first memory, specifying a plurality of locations of metadata for a plurality of stages of basic input/output system (BIOS) initialization. The information handling system may then load first metadata for a first stage of BIOS initialization from a first metadata location of the plurality of locations specified by the first data. The first metadata may contain information for indexing first initialization data located at a first initialization data location. The information handling system may then index the first initialization data of the first initialization data location based, at least in part, on the first metadata. The information handling system may then perform the first stage of BIOS initialization based, at least in part, on the first initialization data.

Abstract: Upon detection of a change in resolution from a first resolution to a second resolution, one or more user interface elements may be dynamically scaled based, at least in part, on the detected change in resolution. The user interface elements may be dynamically scaled in such a way as to maintain an aspect ratio of each of the user interface elements while adjusting a resolution of each of the user interface elements to the second resolution. After the user interface elements are dynamically scaled, a user interface, at the second resolution, may be presented on a display of an information handling system.

Abstract: Systems and methods to stage firmware capsule package for an external device in a firmware client system. The firmware client system may include a basic input/output system (BIOS) and an operating system (OS). The BIOS may create a virtual device. The OS may download a virtual device driver package associated with the virtual device from an update service. The virtual device driver package may include a first virtual device driver and a first external device firmware. The OS may also install the first virtual device driver of the virtual device driver package, stage the first external device firmware on a storage device, and execute the first virtual device driver. The first virtual device driver may, when a first external device associated with the first external device firmware is available, deliver the first external device firmware to the first external device using an update firmware mechanism.

Abstract: Logging downhole exposes components of logging tools, for example, antennas to abrasive and erosive operating conditions. A protective sleeve may disposed about an antenna assembly to protect the antenna assembly for the downhole operating conditions. To permit transmission and receipt of signals by and too the antenna assembly, slots are formed or disposed in the protective sleeve. A non-conductive composite insert is formed in the slots to protect the internal components of the protective sleeve, for example, the antenna assembly, from the operation conditions. A non-conductive composite inner liner is formed in an annulus of the protective sleeve and adheres to the protective sleeve and the non-conductive composite insert. The non-conductive component insert and inner liner allow signals to be transmitted and received by the antenna assembly so that logging operations can be completed without undue delay and the expense of repairing or replacing worn or damaged components.

Abstract: A heuristic learning algorithm uses an ALS to determine display brightness settings based on a stored response curve for display brightness for a user. When the user overrides the response curve value for display brightness at a given ALS output, the display brightness setting based on the user input is used to modify the response curve for the ALS output to lesser extent than the user input. Over time the response curve will approach desired user settings for each value of the ALS output.

Abstract: Systems described herein apply visual computer-generated elements into real-world images with an appearance of depth by using information available via conventional mobile devices. The systems receive a reference image and reference image data collected contemporaneously with the reference image. The reference image data includes a geo-location, a direction heading, and a tilt. The systems identify one or more features within the reference image and receive a user's selection of a foreground feature from the one or more features. The systems receive a virtual object definition that includes an object type, a size, and an overlay position of the virtual object relative to the foreground feature. The virtual object is provided in the virtual layer appearing behind the foreground feature. The systems store, in a memory, the reference image data associated with the virtual object definition.

Abstract: Systems described herein allow for placement and presentation of virtual objects using mobile devices with a single camera lens. A device receives, from a first mobile device, a target image captured from a camera and target image data collected contemporaneously with the target image. The target image data includes a geographic location, a direction heading, and a tilt. The device receives, from the first mobile device, a first virtual object definition that includes an object type, a size, and a mobile device orientation for presenting a first virtual object within a video feed. The device generates a simplified model of the target image, and stores the first virtual object definition associated with the target image data and the simplified model of the target image. The device uploads the first virtual object definition and the target image data, so the first virtual object is discoverable by a second mobile device.

Abstract: A method for automatic correction of nonvolatile memory in information handling systems includes storing ECC data for a compressed BIOS firmware. The ECC data are used to identify and correct error bits in the compressed BIOS firmware. The discovered error bits are recorded in the nonvolatile memory and accessed for a faster correction method for the compressed BIOS firmware than using the ECC data on subsequent attempts.
