Abstract: A rotatable circular waveguide structure is described that may comprise circular waveguide sections configured to propagate electromagnetic radiation. The circular waveguide sections may enable data signals to be transmitted between portions of an electronic device, such as a chassis and display portion, which may be rotatable with respect to one another. The rotatable circular waveguide structure may comprise one or more circular waveguide sections that are routed through a hinge of the electronic device, as well as one or more rotatable junctions. The rotatable junctions enable a rotation of circular waveguide sections with respect to one another as the coupled portions of the electronic device are also rotated. The rotatable circular waveguide structure may replace the use of data cables that are conventionally used to carry data signals between portions of an electronic device.

Abstract: Electrically conductive compressible gaskets can be employed to ground a heat solution and provide electromagnetic interference (EMI) shielding. A plurality of gaskets may be arranged around the perimeter of an integrated circuit package such as a processor or system on a chip. Each of the gaskets is in contact with a ground plane in the package, and upon contact with a heat sink or cold plate, creates an electrical path that grounds the heat sink or cold plate and thereby minimizes the emission of spurious radio signals. Other embodiments may be described and/or claimed.

Abstract: An input by-pass circuit for a current probe has first and second switches coupled between current probe inputs and current sensing circuit inputs. A switch control is coupled to the switching circuit for selectively coupling and decoupling the current probe inputs to the current sensing circuit such that the current signal continuously flows in the device under test.

Abstract: A current probing system has a current probe and a detachable adapter. The current probe has a probe body with electrically conductive contacts that mate with electrically conductive contacts on the adapter. Leads extend from the adapter for coupling to a current carrying conductor. The leads can connect to a plug that is coupled to a current diverting device for coupling a current signal to the current probe. The adapter may also include a switch that selectively couples the current signal to the current probe when the adapter is mated with the current probe. The contacts of the current probe are coupled to a current sensing circuit which generates a voltage output representative of the current signal. The voltage output is coupled to an oscilloscope via an electrical cable.

Abstract: A probe holder for a signal acquisition probe has a cradle receiving the signal acquisition probe and a pedestal adapted for receiving substrates of various thicknesses. The pedestal has a base member and an upright member with the upright member coupled to the cradle. The base member has at least a first lateral slot formed therein having a plurality of clearances for receiving substrates of varying thicknesses.

Abstract: The pedal assembly includes a pedal and a rod is movably extended through a passage defined longitudinally through the pedal. A side part is connected to one side of the peal and includes two chambers defined therein. The two chambers define two openings communicating with the passage and two a hole through an outside wall of the side part. The rod has a plurality of notches defined in one side thereof and the notches are in communication with each other. Two pins respectively and movably extend through the two holes, the two chambers and the two openings and are engaged with the notches to position the pedal relative to the rod. Each pin has a spring mounted thereto so that the pins extend into the notches when the user releases them.

Abstract: The pedal assembly includes a pedal having a rectangular passage defined longitudinally therethrough and a plurality of first positioning holes are defined through one side of the peal. A rod movably extends through the passage and includes a plurality of second positioning holes defined in one side thereof so that the pedal is positioned relative to the rod by inserting two pins through aligned first positioning holes and second positioning holes.
