Abstract: A portable computing device includes an antenna within its housing structure for wireless connectivity, where an upper partition of the housing structure is used to construct an antenna plane, and a ground plane is incorporated into a lower partition of the housing structure. In some cases, the antenna is capable of maintaining wireless connectivity over a wide frequency band. Some embodiments include a device mount external to the upper partition and the lower partition of the housing structure that enables mounting the portable computing device to another entity, such as a user. In some cases, the device mount is external to the antenna used by the portable computing device, and does not include any portions of the antenna.

Abstract: A header plate (20) is provided for receiving the flattened tubes (14) of a heat exchanger. The header plate (20) includes a plurality of tube receiving openings (26), with each of the openings being surrounded by a flange or collar (28) that extends from a base wall (24) of the header plate (20) towards the heat exchanger core (12) to surround the exterior cross section of the associated tube (14). Each of the flanges (28) is shaped to conform to the exterior of the associated tube (14), and a blend radius R is provided at the interface between the base wall (24) and the flange (28). The blend radius R has a size that increases from a radius R1 central to the length of a long side wall (30) of the flange (28) to a radius R2 central to the length of a short side wall (32) of the flange (28).
