Abstract: Methods, systems, and apparatus for EM communications. One of the methods includes determining, at a first device, that a second device is present; initiating a half duplex communication with the second device; configuring communication with the second device including determining whether full duplex communication is available; in response to a determination that full duplex communication is not available, communicating with the second device in half duplex mode; and in response to a determination that full duplex communication is available, communication with the second device in full duplex mode.

Abstract: A test system includes a test socket assembly for capturing low energy electromagnetic emissions from radio frequency (RF) integrated circuits (ICs). The test socket assembly is structured to direct electromagnetic radiation from the device under test (DUT) to a socket port coupled to one end of a waveguide for transmission to a tester. The combination of the materials comprising the socket assembly is selected to more efficiently couple electromagnetic emissions from the DUT into the waveguide. For example, a reflective plane with an adjustable position may be located below the DUT in order to increase coupling of electromagnetic radiation from the DUT into the waveguide.

Abstract: An adapter may facilitate easy and swift data transfer amongst two previously incompatible electronic devices. Such an adapter may be operative to communicate data with a first of the two electronic devices using a contactless communication link and a first communication protocol and to communicate data with a second of the two electronic devices using a mechanical communication link and/or using a second communication protocol that is different than the first communication protocol, such that data may be transferred between the first and second electronic devices via the adapter. The adapter may be communicatively coupled to both the first electronic device and the second electronic device at the same time. The adapter may rapidly transition between communicating data with the first device and communicating data with the second device (e.g., without altering a physical connection between the adapter and one of the first and second devices during such a transition).

Abstract: Systems, methods, and apparatus for regenerating a data signal and a clock signal are provided. One of the apparatuses include clock regeneration loop circuitry configured to receive an input data signal transmitted without a reference clock signal, and to generate an output reference clock signal having an adjustable clock frequency that substantially matches a data rate of the input data signal; data detection loop circuitry configured to generate a phase offset control signal for adjusting a phase of a clock signal that samples the input data signal, and to generate, based on the phase offset control signal, a sampled input data signal; and an elastic buffer configured to generate, based on the output reference clock signal and the sampled input data signal, an output data signal that substantially aligns with the output reference clock signal, and enable the different adaptation dynamic of the loops.
