Abstract: A system for battery current monitoring includes a system power throttle stored in memory and executable by the one or more processors to place a battery of an electronic device into a state of expected zero-drain throughout a time interval while the electronic device remains active, and a battery leakage monitor stored in the memory and executable by the one or more processors to detect a battery charge leak based on a series of time-separated parameter measurements for the battery collected during the time interval.

Abstract: Micro-hole structures are described herein that may be implemented for device ventilation, protection, and design. The micro-hole structures include multiple micro-holes that are imperceptible to users at ordinary viewing angles and distances, and are thus porous structures that appear to be solid. A micro-hole structure may be formed as a housing of a device or as a structure to be attached to the housing of the device. A device with a micro-hole structure housing enables thermal ventilation from heat-producing components located within the housing. Additionally, micro-holes of a micro-hole structure may be organized to operate as a design element for the device while simultaneously providing ventilation. The micro-holes are sufficiently small to allow for passage of air through the micro-hole structure while also prohibiting entrance of water and/or other contaminants into the housing of the device.

Abstract: A stub directory is written out to a storage device for multiple files in a container file, the stub directory including identifiers of the multiple files but excluding data of the multiple files. In response to a request to access one file of the multiple files, the data of the one file is written out to the storage device. A requested modification is allowed to be performed on the one file written out to the storage device to generate a modified version of the file. After modification of the one file is completed, a previous version of the file in the container file is replaced with the modified version of the file.

Abstract: One or more levels of a stub directory from a container file are written out to a storage device. The stub directory initially includes identifiers of one or more directories in the one or more levels of the stub directory but not identifiers of additional directories in the one or more directories. In response to a request to access one of the one or more directories, identifiers of one or more additional directories and/or one or more files in the one directory are extracted from the container file.
