Abstract: A watchband can comfortably secure an electronic device to a wrist of a user. The watchband can include a base having a contact surface opposite an engagement surface, contact loops on the contact surface for contacting a user, and engagement loops on the engagement surface for engaging hooks. The hooks can be provided on the engagement surface, opposite some of the contact loops. Edge sections of the base can wrap around a central section to define an end of the base. A tab can extend from an end of the base to facilitate attachment, adjustment, and/or removal of the watch band. The tab can further help maintain the assembled parts in place to enhance durability of the watchband.

Abstract: Bands for wearable devices include multiple band retainers used to maintain engagement between an assembly (e.g., a pair) of bands. Some band retainers may be permanently affixed with the band at a certain location of the band, while other band retainers can be removable. The removable band retainers can be moved to different locations of the band, thus allowing the band retainer to retain another band at different locations. As a result, the assembly of bands can be used with different users, and in particular, users with different wrist sizes. Moreover, using multiple band retainers can provide an engagement force between the bands to withstand higher-impact events, such as swimming and diving. Additionally, bands and band retainers may include one or more liquid-resistant and corrosion-resistant materials.

Abstract: A polymer battery separator with an interpenetrating network structure and a preparation method thereof are disclosed. A multilayer microporous separator includes a PVDF layer, and a PE-PVDF porous substrate located on a surface of the PVDF layer. Finger-like through holes with a pore size of 100-150 nm are distributed in the PVDF finger-like pore layer. An interpenetrating network structure with a pore size of 50-100 nm is distributed on an interface between the PVDF finger-like pore layer and the PE microporous layer. Micropores with a pore size of 20-50 nm are distributed in the PE microporous layer. The surface of the PVDF layer is covered with the PE-PVDF porous substrate, so that the multilayer microporous separator forms an interpenetrating network structure, which has improved thermal stability and high-temperature resistance.

Abstract: Fuse holders having a fuse clip assembly configured to support resilient fuse clip arms when subjected to a compression force and also configured to support the resilient fuse clip arms when subject to an expansion force. The bias element is movable relative to the fuse clip arms between first and second positions and prevents deformation of the fuse clip arms.

Abstract: An inline fuse holder assembly encloses a fuse assembly including a fuse, and first and second wire connectors at respective first and second longitudinal ends of the fuse assembly. The inline fuse holder assembly includes first and second components including respective first and second connectors. The first and second connectors include mateable, non-releasable connection components configured to connect the first and second components to one another and form a substantially waterproof, non-releasable connection upon connection. The first and second components together define an enclosure for enclosing an entirety of the fuse assembly when the first and second fuse holder components are connected to one another.
