Abstract: A waterproof modular electrocardiogram (ECG) electrode assembly for use in a wearable cardiac monitoring device comprises a first, main circuit board comprising active ECG processing circuitry encapsulated in a waterproof moldable dielectric polymer, and an ECG electrode mechanically coupled to the waterproof moldable dielectric polymer, the ECG electrode configured to be electrically coupled to a portion of the main circuit board.

Abstract: An electrical connector for electrically connecting a terminal to a cord of a peripheral device, the electrical connector including a plug member, a lever arm pivotally attached to the plug member, and a biasing member. The plug member and lever arm each include an engagement claw adapted to engage complementary surfaces on the terminal, and the biasing member imparts a biasing force on the lever arm to force the engagement claws to close onto the complementary surfaces on the terminal. The lever arm advantageously includes a first gripping surface with a contoured concave profile for a user to apply a releasing force against the biasing force to remove the plug member from the terminal. A second surface includes a concave surface for engaging a user's finger and forming a grip bump.

Abstract: A cord assembly for an electronic device includes a cord having an insulation layer with a first end and an exterior surface, as well as at least one electrical conductor extending within the insulation layer. A strength member also extends within the insulation layer and includes a first end extending beyond the first end of the insulation layer. A securing element couples the first end of the strength member with the first end of the insulation layer along the exterior surface. The strength member is pre-tensioned to carry any additional tensile loads on the cord, at least initially. The cord assembly may also include a strain relief member molded over the first end of the strength member and the securing element.

Abstract: A headset includes an element to be held to the head of a wearer and a headband coupled to the element and configured for engaging a head of a wearer to hold the element thereon. The headband includes a plurality of headband arms coupled to pivot with respect to each other. A torsion spring is positioned between the arms and portions of the torsion spring are coupled to the arms for acting on the arms with a torsion force. An adjustment member is coupled between the torsion spring and a headband arm and is operable for adjusting the torsion force of the torsion spring to adjust the torsion force on the arms.

Abstract: Embodiments of the invention provide for a headset and system including a portable device, wherein the headset includes an electrically conductive band configured to engage a portion of a head of a user and coupling together a headpiece and an earpiece assembly. The headpiece includes an electrically conductive portion that is configured to engage and electrically couple to the user's head. The headpiece is electrically coupled with the conductive band. The earpiece assembly is coupled with the conductive band to engage an ear of a user and has a ground conductor that is electrically coupled between the conductive band and a portable device for coupling the portable device to the head of a user for reducing electrostatic discharge at the head of the user of the portable device.
