Patent ID: 8878602

Claim:
A computing device for managing noise effects in an electronic environment, comprising: an antenna configured to at least receive or radiate a radio frequency (RF) signal, the antenna being coupled to a receiver of the computing device; a port for receiving at least a portion of a first connector of a communication cable, the communication cable configured to couple the computing device to an electronic device, the communication cable having a second connector for connecting to the electronic device; and noise reduction circuitry including at least an electronic switch, the electronic switch configured to: detect a biasing signal from the electronic device, the biasing signal being provided by the electronic device via the communication cable at least when the first connector of the communication is connected to the port of the computing device and the second connector of the communication cable is connected to the electronic device, operate in a first position, in response to detecting the biasing signal, to couple the first connector of the communication cable to a ground of the computing device, and operate in a second position while not receiving the biasing signal, the second position providing an open circuit between the first connector of the communication cable and the ground on the computing device.
