Abstract: A rotary joint is provided. The rotary joint includes a stator and a rotor. The stator includes a stator housing, a first wireless communication platform device having a first wireless communication module connected to a plurality of data signal lines of the stator and at least one power line of the stator, and a first antenna. The rotor is configured to be actuated in a rotational manner relative to the stator, and the rotor includes a rotor housing, a second wireless communication platform device comprising a second wireless communication module connected to a plurality of data signal lines of the rotor and at least one power line of the rotor, and a second antenna. The first wireless communication platform device and the second wireless communication platform device are configured to communicate operational data with one another via the first and second antennas.

Abstract: A redundant clock module provides a highly reliable fixed clock reference output. This clock reference output is based on at least two internal reference oscillators that are monitored and eliminated from use if they are not operating or within tolerance requirements. The redundant clock module comprises at least two oscillators, detection circuitry, switching circuitry and control circuitry. If a primary oscillator fails or is out of tolerance, the redundant clock module will detect the failure or out of tolerance condition and switch to a secondary working and in tolerance oscillator to take over primary timing functions of an end user application. The redundant clock module provides a slow and seamless transition between oscillator switching to assure no significant phase shift or runt pulses will affect the end user application.
