Patent number: 9136912Abstract: A non-contacting rotary interface has a first core with a first pair of balanced transmission lines coupled to the first core and a second core moveable in relation to the first core with a second pair of balanced transmission lines coupled to the second core and configured to receive signals from the first pair of balanced transmission lines. The first pair of balanced transmission lines has a first transmit wire coupled to a termination point at a first end of the first transmit wire, a first transmitter coupled to the first transmit wire at a second end of the first transmit wire, a second transmit wire coupled to the termination point at a first end of the second transmit wire, and a second transmitter coupled to the second transmit wire at a second end of the second transmit wire. The balanced transmission lines may be electrical traces on a circuit board.Type: GrantFiled: March 19, 2012Date of Patent: September 15, 2015Assignee: Voxis, Inc.Inventors: Joseph Newhall West, Jon Robert Kiser, Jerry Samuel Dimsdale

Patent number: 8452561Abstract: A time differential is estimated between a plurality of signals by determining a filter response of a first electrical signal with a first filter array, determining a filter response of a second electrical signal with a second filter array, and determining, based at least on the filter response of the first electrical signal and the filter response of the second electrical signal, a time differential between the first electrical signal and the second electrical signal. A first optical signal is converted into the first electrical signal and a second optical signal is converted into the second electrical signal. The filter response of the first electrical signal and the filter response of the second electrical signal are sampled and the time differential between the first electrical signal and the second electrical signal is determined based at least on the sampled filter response of the first electrical signal and the sampled filter response of the second electrical signal.Type: GrantFiled: January 31, 2011Date of Patent: May 28, 2013Assignee: Voxis, Inc.Inventors: Jerry Samuel Dimsdale, Joseph Newhall West, Andrew Philip Lewis, Thomas Rahjit Singh Gill
