Abstract: Modular sealed battery packs configured to provide enhanced performance and safety features, along with associated apparatus, systems, and methods for monitoring and controlling operation and use of such battery packs and associated coupled devices and systems are disclosed.

Abstract: A user interface device including a floating actuator sub-assembly and a base assembly flexibly coupled to the floating actuator assembly is disclosed. The floating actuator assembly may include a magnet array assembly with a plurality of magnets fixed relative to each other. The user interface device may further include a deformable actuator sub-assembly, which may include a magnet array assembly with a plurality of magnets in a movable configuration relative to each other. A base assembly may include multi-axis magnetic sensors corresponding to the magnets in the magnet arrays to sense position of motion of the magnets during user displacements and/or deformation of actuator elements of the user interface device.

Abstract: User interface devices using magnetic sensing to provide output signals associated with motion and/or deformation of an actuator element of the interface devices are described. The output signals may be provided to an electronic computing system to provide commands, controls, and/or other data or information. In one embodiment, a user interface device may include a plurality of permanent magnets and a plurality of multi-axis magnetic sensors to generate motion and/or deformation signals to be provided to a processing element to generate the output signals.

Abstract: Various finger tip controlled manual interface devices that can be used as inputs to personal computers, electromechanical systems and video game consoles utilize concentrically arranged magnets. The polarities of the magnets are oriented to provide restoration forces on a one of the magnets to bias it toward a neutral position. A magnetic sensor including a plurality of sensing elements such as Hall effect devices generates output signals representative of direction and amount of movement of the magnet that is biased to the neutral position.
