Abstract: A clock source outputs a clock signal. A first delay line receives a first clock source signal and produces a first output, the first clock source signal at least partially based on the clock signal. A first clock spine receives the first output and produces a global reference clock signal. A second delay line receives a second clock source signal and produces a second output, the second clock source signal at least partially based on the clock signal. A second clock spine receives the second output and produces a global feedback clock signal. A global phase detector detects a phase difference between the global reference clock signal and the global feedback clock signal to produce a global phase detector output. The second clock source signal is controlled at least partially based on the global phase detector output.

Abstract: A coupler optionally couples two sets of conductive wires. In some embodiments, the coupler includes a body having a first end with a first set of at least two holes and a second end with a second set of two holes. Optionally each hole includes a clamp. Optionally, each clamp of said first set of holes is conductively connected to at least one clamp of said second set of holes. In some embodiments a first rotating element simultaneous attaches to said coupler a first set of a plurality of wires inserted into said first set of holes and/or a second rotating element simultaneous attaches to said coupler a second set of a plurality of wires inserted into said second set of holes.

Abstract: A connector device including a device body having a first end and a second end, a first plurality of slots formed in the device body, the first plurality of slots having a second plurality of openings formed at the first end of the device body and a third plurality of openings formed at the second end of the device body, the second plurality of openings being adapted for insertion of a first set of conductive wires therein, the third plurality of openings being adapted for insertion of a second set of conductive wires therein, a multiplicity of conductive clamping elements disposed in the first plurality of slots, the multiplicity of clamping elements including a first clamping spring disposed within each of the second plurality of openings for clamping the first set of conductive wires therein and a second clamping spring disposed within each of the third plurality of openings for clamping the second set of conductive wires therein, a first fastening ring rotatable over the first end of the device body for s

Abstract: An earphone comprising a moving part, adapted to close an auditory port thereby toggling the earphone from an open mode allowing environmental sounds to reach an ear of the user to a closed mode blocking the ear of the user. The closing is accomplished while the earphone is in operation. The sound capsule of the earphone may also be activated and deactivated according to the mode of the earphone.
