  • Patent number: 10840720
    Abstract: For selectively restricting the charge level of a battery, methods, apparatus, and systems are disclosed. One apparatus includes a battery, a temperature sensor that measures a temperature of the battery, a processor, and a memory that stores code executable by the processor. Here, the processor selects a maximum charge level using the temperature of the battery, where the maximum charge becomes less than a full charge level of the battery in response to the battery temperature being above a threshold temperature. Moreover, the processor restricts charging of the battery to the maximum charge level in response to the temperature of the battery being above the threshold temperature.

  • Patent number: 10819122
    Abstract: In one aspect, a device includes system components and a battery pack. The battery pack includes one or more cell balancing resistors, plural battery cells in a circuit with the one or more cell balancing resistors, at least one processor, and storage accessible to the processor. The storage includes instructions executable by the processor to determine whether a threshold amount of time has accrued during which the device has not been operated on battery power and, responsive to a determination that the threshold amount of time has accrued, employ the one or more cell balancing resistors of the battery pack to reduce the charge level of the plural battery cells.

  • Publication number: 20200291196
    Abstract: Apparatuses, methods, and systems are disclosed for attaching structures. One system includes: a device having a first structure attached to a second structure; a first polymer coupled to the first structure, wherein the first polymer has a first temperature profile and a first shape; and a second polymer coupled to the second structure. The second polymer has a second temperature profile and a second shape. The second shape interlocks the first shape. The first polymer and the second polymer secure the first structure to the second structure in response to the first polymer and the second polymer being in a first temperature range. The first polymer and the second polymer release the first structure from the second structure in response to the first polymer and the second polymer being in a second temperature range different from the first temperature range.

  • Patent number: 10474201
    Abstract: An electronic apparatus includes a base subassembly and a display subassembly. A hinge is rotatably coupled to the base subassembly and the display subassembly. The hinge allows the base subassembly and the display subassembly to rotate about an operating axis to change a rotational orientation of the display subassembly relative to the base subassembly. An elevation mechanism is operatively coupled to the hinge. The elevation mechanism includes a support tray disposed in the base subassembly that holds the mechanical elements. The elevation mechanism is responsive to torque that changes the rotational orientation of the display subassembly such that the elevation mechanism lifts the support tray when the display subassembly is moved to an upright position and lowers the support tray when the display subassembly is moved to a closed position.
