Abstract: A device such as an autonomous mobile device may include an extensible mast or other structure that changes length during operation. A cable between electronics at the ends of the structure includes a data line for signals and a power line for electrical power. A deployed length of the cable is determined and used to determine the phase of an antinoise signal that is radiated using the power line. The antinoise signal destructively interferes with at least a portion of the radiated noise from the data line, reducing the overall amplitude of the radiated noise. The deployed length may also be used to adjust other parameters, such as equalizer settings for one or more of a transmitter or receiver that is connected to the data line.

Abstract: Technologies for dynamic noise cancelation using noise patterns are described. One device includes a moveable assembly having first and second degrees of freedom. A component within the base assembly radiates electromagnetic energy in a radiation pattern as a noise source when operating and an antenna, coupled to a receiver, is disposed on the support member. The processing device, using noise profile data about the radiation pattern of the noise source, determines that the component is operating and a current angle between the component and the antenna. The processing device determines a difference value between the current angle and the first angle and causes the moveable assembly to move at least one of the antenna or the base assembly according to the difference value.
