Abstract: Implantable medical devices include an enclosure that is constructed by machining of a material rather than by forming or stamping. The machining produces one or more internal features within the enclosure. These internal features may include shelves that may act as a stiffener and create separate compartments within the enclosure. These internal features may include contoured edges along the shelves to accommodate conductors and other structures that extend from one compartment to another. These features may include slots that are present in one or more locations, such as on a surface of one of the shelves. These internal features may also include standoffs that establish a gap between an internal component and the external wall of the enclosure. These internal features may also include different thicknesses in different areas of the enclosure, such as one wall thickness in one compartment and a different wall thickness in another compartment.

Abstract: In an example, a smart battery backup system is disclosed. The system is configured to be installed on or within a vehicle and connected to a main battery of the vehicle. The system includes a housing, a lithium-ion battery disposed at least partially within the housing, and a controller disposed at least partially within the housing and including a set of momentary switches. The controller is configured to jump start the main battery using the lithium-ion battery. The controller is also configured to maintain the lithium-ion battery such that, based on a charge state of the lithium-ion battery and a charge state of the main battery, the lithium-ion battery is charged using the main battery.
