This invention offers an improved hands-free device for coupling to radio devices having mute and audio inputs. The invention couples serially between the radio and a portable electronic device such as a mobile telephone. The invention facilitates the delivery of appropriate audio signals to the radio. The invention also senses the activity of the portable electronic device and actuates a mute signal upon sensing such activity. The mute signal causes the radio to switch the input to its loudspeakers from a received signal to the audio being delivered by the invention from the portable electronic device. In so doing the invention offers an easy to install, inexpensive hands-free unit that takes advantage of the high fidelity loudspeakers in the automotive stereo system.

A battery pack (10) including at least one battery cell (26) and a circuit carrier (30) in proximity to the battery cell. Disposed in the battery pack, is a fuse (50) which is formed from an electrically conductive resilient material adapted to work as the fuse. The electrically conductive resilient material further is encapsulated with a material adapted to promote resistance to breakage due to shocks, bumping or droppage of battery packs into which the fuse is incorporated. When the temperature of the at least two battery cells reaches a predetermined trip point, the fuse releases from at least one of the batteries, due to the heat transfer from the battery cell, electrically disconnecting the battery cell from adjacent battery cells.

A circuit assembly (100) includes a circuit carrier (102) and a solder pad (104). Circuit carrier (102) further includes at least one vent (108) formed in the circuit carrier (102) for venting gases developed during the process of soldering a component or contact (110) to solder pad (104). The one or more vents (108) prevent solder gases to get trapped in the solder joint during the soldering process. Without vent(s) (108) if the contact (110) to be mounted is substantially the size of the solder pad (104) or larger, gases would tend to be trapped and cause the solder joint to weaken.

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 battery pack (10), comprises at least one cell (16) having a positive (15) and a negative terminal (17), and a header (18) for mounting the cell. The header has at least one wiping contact (20) for connection to either the positive or negative terminal of the cell or cells. The battery pack further comprises a first housing member (30) for receiving the header and the cell or cells, a second housing member (12) mounted above the header and coupled to the first housing member, and a scheme for wiping the wiping contact while the cell (or cells) is enclosed within the first and second housing members.

A circuit assembly (400) includes a flexible circuit (402) having first (504) and second layers (502). A current-limiting device such as a nichrome strip (316) is coupled to the flexible circuit (402) for limiting the amount of current during a short circuit condition. A heat sink (404) is selectively placed between the first and second layers of the flexible circuit in thermal proximity to the nichrome wire (316) in order to dissipate some of the heat generated by the nichrome strip (316).
