Abstract: A wearable device has a flexible and extendable body configured to encircle a portion of a body of a user, an electronics module with a concave space between two ends, each end attachable to the flexible and extendable body with a flexible retention mount to allow rotation of the flexible and extendable body relative to the electronics module and to transfer tension force from the flexible and extendable body to the electronics module, and a bio-signal sensor disposed on the flexible and extendable body to contact at least part of the body of the user and to receive bio-signals from the user.

Abstract: An eyeglass frame includes a front portion (130) for holding two lenses, an assembly for attaching to a signal pod (110), side arms (140, 150) connected to the front portion (130), a nose assembly (160) connected to the front portion (130) and also includes nose contacts (162, 164) for supporting the front portion (130) on the user's nose. The nose contact (162, 164) is electrically connected to the signal pod (110), and an adjustable ear piece (1402) connected to the side arms and includes head contacts in contact with a user's head and ears. The head contacts are electrically connected to the side arms (140, 150) and the signal pod (110), the adjustable ear piece being formable or malleable to conform to the user's head and ears.
