An electronic device, for example a smoke alarm, that includes a battery carrier that includes a push to open and push to close apparatus for opening and closing the carrier. The main portion covers a portion of the area from the shaft of the first proximal phalanx to the shaft of the second proximal phalanx, the medial first flexible portion covers a portion of the area from the shaft of the first proximal phalanx to the head of the first metatarsal bone, and the lateral first flexible portion extends to the lateral side of the foot from the main portion. Additionally, the intramedullary nail utilizes a threaded slot on the body thereof, for engaging locking screws for fixation of the intramedullary nail within a bone of a patient. The system may include support for messaging between threads, messaging with time andor event stamps, epochs to ensure consistency, and ancillary structures such as render-bins, geometry structures, and rendering environment structures. A method of manufacturing the flexible circuit compression connector system that includes a compression assembly by forming the contacts into a preselected configuration and securing the contacts to the flexible substrate is also included.
