Abstract: Techniques for verification of interchangeable connectors are disclosed which include applying one or more identification tags to connectors. The identification tags have identifiers which may be associated with one another for connectors that correspond. The identifiers may be read from the identification tags when the connectors are connected to determine if the connected connectors are associated.

Abstract: According to embodiments of the present invention, a UWB (ultra wideband) communication system is employed to wirelessly test and configure circuits on a die. Baseband signals may be utilized with resulting simplification in CMOS circuits, or orthogonal frequency division multiplexing may be employed to allow more than one communication channel. In one embodiment, the antenna for communicating with circuits on a die is placed between the package and the heat spreader, in electrical contact with a solder bump. In another embodiment, the antennas are placed onto wafer scribe lines, and are used to test chips before the wafer is sawed. Other embodiments are described and claimed.
