Described is a battery cell housing comprising a battery cell compartment and a latching compartment separated by an inner wall, where the battery housing is made of metal formed by combination extrusion or dual impact extrusion. This permits battery compartment wall to be thin, so that the maximum size battery cell may be inserted into it, and the latching compartment wall to be thic,k so it can be securely fastened to an electronic device. The inner wall provides an impenetrable barrier to moisture migrating from the latching compartment to the battery compartment.

Battery cell housing

An electrical device (40) has a contact (58) for electrically interconnecting with a second device. The contact (58) is disposed on a rib (60) extending downward from the top of an upper housing (42) of the electrical device. The contact (58) has a cantilevered arm extending from a downward portion (68), and terminates in a contact head (78) which extend upwards through an opening (56). The downward portion (68) of the contact (58) has a contact point (72) for contacting an exposed conductor (50) deflectably mounted on a printed circuit board (46), which is disposed in a lower housing (44). When the upper and lower housings (42) and (44) are assembled together, the contact point (72) is pressed against the exposed conductor (50), deflecting it, and forming a gas tight solderless electrical connection.

Electrical device having a solderness electrical contact

A device (100) having an external contact electrical connection (155) for providing an electrical interface to the device includes a housing member (222) having apertures (235, 335), and a flexible film substrate (270) having an electrically conductive pattern (275). Portions of the electrically conductive pattern defines contact areas (255, 355) for presenting the electrical interface of the device (100). These contact areas (255, 355) are rigidly positioned adjacent to the interior surface (324) of the housing (222) about the apertures (235, 335) such that the contact areas (255) are externally exposed through the aperture (235, 335).

Device with external interface

A process for joining at least two ultrathin plastic pieces by an ultrasonic welding method is disclosed. The process includes providing a plurality of energy directors for enhancing weld strength, and reducing unacceptable welds. The process also includes providing a groove in a flanged attachment member to assist in properly orienting the pieces to be joined.

Method for ultrasonically welding thin-walled components

A contact array (20) for electrically connecting an energy source (10) to a radio (35) and a charger (15), comprising a circuit assembly (40) having integral radio, charger, and circuit package contacts (52, 54, 56) extending from one end of the circuit assembly (40). Terminals (66) extend from a second end of the circuit assembly (40) for connecting to the energy source. A circuit package (60) is disposed adjacent the charger contacts (54) to electrically and mechanically support the contacts.

Contact array

A configurable flexible circuit substrate (100) is disclosed. The substrate (100) has an electrical circuit pattern (120) and an integral separable segment (130) containing a portion (132) of the circuit pattern (120). The substrate (100) also includes an integral extraction initiator portion (132), which is pivotable between a first position substantially planar with the surface of the substrate (100), and a second position away from the surface of the substrate (100). The extraction initiator portion (132) develops stress raisers (137) when pivoted toward the second position, and the extraction initiator portion (132) also effects a removal of the separable segment (130) from the substrate (100) when the extraction initiator portion (132) is pulled across the separable segment (130).

Configurable circuit substrate

A method is provided for positioning an object (133) relative to a structural member (103). The method includes providing a first and second member (103, 113), a positioning member (123) with a first end (126) and a second end (124), and the object (133). The first end (126) is positioned proximal to the object (133), and a first energy director (107) is positioned between, and is in contact with, the first end (126) and the first member (103). A second energy director (125), having a slower characteristic melting rate than that of the first energy director (107), is positioned between, and is in contact with, the second end (124) and the second member (123). Energy is first imparted to cause at least one of the first and second energy directors (107, 125) to begin melting. Imparting the energy is discontinued after the first energy director (107) is substantially melted and the object (133) is properly positioned, while the second energy director (125) is not substantially melted.
