    Abstract: A wireless computing device may include an internal antenna, a radio frequency (RF) transmission path that is switchably connectable to the internal antenna, a Universal Serial Bus (USB) connector configured to connect to an external antenna, a detector configured to detect if an external antenna is connected to the USB connector, and an antenna selector configured to (1) connect the internal antenna into the RF transmission path if the detector detects that no external antenna is connected to the USB connector and (2) disconnect the internal antenna from the RF transmission path and connect the external antenna into the RF transmission path if the detector detects that the external antenna is connected to the USB connector, thereby improving the wireless transmission/reception performance of the internal wireless module of the wireless computing device.

    Abstract: A communication system communicates data elements on a conducting wire. In an embodiment, a sequence of data elements to be transmitted is electrically represented on a pair of terminals, and a transmission element located at a first portion of the conducting wire transmits the sequence in the form of a wave on a surface of the conducting wire. The transmission element includes a first conductor wrapped around the first portion of the conducting wire, a first insulator located between the first conductor and the first portion of the conducting wire, and a conductive structure disposed around the first conductor. The conductive structure has a narrow cross section at one end and extends outwardly to a broader cross section at the other end. A first terminal of the pair of terminals is electrically connected to the first conductor and the second terminal is electrically connected to the conductive structure.

    Abstract: Technologies for a metal chassis for an electronic device are disclosed. A manufacturer may manufacture a chassis of an electronic device by machining a recess into a chassis preform and perform an anodization of the chassis. The manufacturer may machine the side of the chassis preform opposite the recess to a predefined thickness, and then perform a subsequent anodization. The predefined thickness is selected so that, after the subsequent anodization, there is a single anodized layer between the surface of the recess and the chassis surface on the opposite side. The single anodized layer is non-conductive, allowing electromagnetic signals of an antenna to pass through.
