Abstract: Described in this disclosure are battery contacts for use in electronic devices usable without soldering to a circuit board. The battery contact includes one or more contact features supported by leaf springs. The contact features touch a corresponding pad on the circuit board at time of assembly, providing an electrically conductive pathway. One or more of the battery contacts may include a spring-biased member configured to apply pressure to one or more batteries.

Abstract: Described in this disclosure is a battery retention device which may include an integral gasket configured to provide an interface between a portion of a battery compartment and a circuit board. The battery retention device may comprise an elastomeric material and one or more retention features configured to prevent Euler buckling in batteries positioned in tandem with one another.

Abstract: This application discloses a method of preparing an assembly. A base assembly is provided and includes a base, and a second fastener structure coupled to the base at a joint. The base assembly is then attached to a receiving element that is configured to physically receive a module and includes a first fastener structure. The first fastener structure is fastened with the second fastener structure and provides a first degree of freedom of motion of the receiving element with respect to the base, and the movement of the receiving element is unlimited in a first direction of travel associated with the first degree of freedom of motion. The receiving element is rotated along the first direction of travel until the receiving element reaches a nominal position at which the receiving element and the module received thereby are configured to face substantially up when they are flipped down via the joint.
