Abstract: A method is described for managing an operating state of a battery energizing a mobile device. Active elements of a “gas gauge” IC component of the mobile device are configured or programmed based on instructions related to tracking capacity aging of the battery. An event is targeted based on the configured or programmed instructions. The targeted event corresponds to reaching an end of a discharge state of the battery, or to reaching a midpoint (relative to full charge) of a charging state of the battery. A relaxation state is induced in the battery upon the targeted event occurring.

Abstract: An electronic device having a battery may be diagnosed and indicated for repair by extracting a log from the electronic device. The log may include a record of battery events including a battery serial number, a battery status, and a battery voltage. The log may be analyzed for battery charge events recorded in the log to determine if the battery is out of tolerance. If the battery is out of tolerance, the battery may be identified as needing replacement.

Abstract: In some examples, a portable data terminal (PDT) is configured to vibrate when it is installed in a base (e.g., of a docking station), which may help improve the electrical contact between the PDT and the base. For example, when the PDT is installed in a base and subsequently vibrated, the electrical contacts of the PDT may vibrate against opposing electrical contacts in the base, which may help remove contaminants, such as dirt and other debris, from between the electrical contacts of the PDT and the base.

Abstract: A Magnetic Resonance Imaging (MRI) system is disclosed. The MRI system includes a cryogenic magnet assembly with a cryogenic vessel housing a superconducting magnet. Disposed radially inboard of the cryogenic magnet assembly are a gradient coil module and a plurality of room temperature steel rings proximate to the gradient coil module. A field of view is defined by at least the superconducting magnet, the gradient coil module, and the plurality of room temperature steel rings. In response to the superconducting magnet being energized, the room temperature steel rings create high order harmonics that serve to expand the magnetic field homogeneity FOV, and low order harmonics that tend to degrade the magnetic field homogeneity within the FOV. The low order harmonics are compensated for by the cryogenic magnet assembly.

Abstract: A shim coil design technique determines a position and a geometry of a room temperature (RT) shim coil to provide both a desired field homogeneity and a desired B0 field setting time. The simultaneous satisfaction of both field homogeneity and field settling time is achieved without a reduction of flux leakage from the shim coil, modification of main magnet protection circuitry, and without necessarily decoupling of the shim coil from the overall main magnet.

Abstract: A magnetic resonance imaging (MRI) magnet having a first section and a second section is disclosed. The first section has a first housing, and a first set of magnet coils arranged about a common axis that include coils proximate the common axis. The second section has a second housing, and a second set of magnet coils arranged about the common axis where the coils are radially displaced from the common axis. The second section is connected to but axially displaced a distance “d” from the first section.

Abstract: Systems, methods and apparatus are provided through which in some embodiments a magnetic resonance imaging (MRI) system includes one or more magnetic shield coils positioned asymmetrically in the casing and also positioned in close proximity to one of two apertures of an inner bore of the MRI system. In those embodiments, the position of the one ore more magnetic shield coils provides an asymmetric magnetic stray field during operation of the MRI system, which in turn allows operation of electronic medical diagnostic equipment or electronic medical monitoring equipment in close proximity to the MRI.
