Abstract: A housing can include a first part and a second part. Each of the first part and the second part can include a first surface, a second surface, a third surface, a fourth surface, and a fifth surface. The second surface can form a first edge with the first surface. The third surface can form a second edge with the second surface. The fourth surface can form a third edge with the third surface. The first part can be attached, via an attachment, to the second part so that the first surfaces form an exterior surface of the housing, the second surfaces abut each other, the third surfaces abut each other, the fourth surfaces abut each other, and the fifth surfaces define an interior space of the housing. The attachment can be within the interior space and can include an ultrasonic weld. The housing can house an antenna.

Abstract: A circuit assembly (600) includes a printed circuit board assembly (100). The printed circuit board assembly includes a first circuit board (101), a second circuit board (102), and a first flexible substrate (103) interposed between, and continuous with, the first circuit board and the second circuit board. A second flexible substrate (108) extends from, and is continuous with, the second circuit board. One or more electronic circuits comprising electronic components (301,302,303,304,305) are disposed along one or more of the first circuit board or the second circuit board. The printed circuit board assembly is folded about a battery (601), with the first circuit board adjacent to the first major face, the second circuit board adjacent to the second major face, and the first flexible substrate spanning the one or more side faces.
