Abstract: Battery packs for electric passenger vehicles are provided. A battery pack can include a housing with a frame and a plurality of structural cross-members defining module spaces for battery modules to be disposed within the housing. The battery pack can also include a lid cover to go over the housing and enclose the battery modules within the housing and lid cover. The structural cross-members can define pairs of horizontally-adjacent module spaces, where pairs of battery modules can be disposed.

Abstract: Battery modules for electric passenger vehicles are provided. A battery module can include a bottom current collector assembly, a lower level positive cell tray, a lower level battery cell array, a lower level negative cell tray, a cooling plate, an upper level negative cell tray, an upper level battery cell array, an upper level positive cell tray, and a top current collector assembly. The battery module can further include side caps and main terminal holders. The battery module can easily be connected to another adjacent battery module and/or to a conductive line in a battery pack.

Abstract: Embodiments of the present invention include an apparatus for encouraging compliance with a prescribed orthotic treatment, including an orthotic device applied to a limb of a user, a strap coupled to the orthotic device, the strap having two ends and configured to wrap around the orthotic device at an attachment area, where a length along the strap is smaller than a maximum circumference of the limb distal to the attachment area, and a locking mechanism to lock the strap onto itself. Other embodiments of the present invention include a system for off-weighting a user's foot, including a hardenable cast; a rigid outer boot having a footbed, a first side strut with a first strap aperture, a second side strut with a second strap aperture, and a strap extending through the first strap aperture and the second strap aperture and operable to tighten around the hardenable cast.
