Methods and systems for mitigating interference between different transceivers in a portable communication device. An electronic control circuit is configured to quantify an electromagnetic isolation between a first transceiver of a portable communication and a second transceiver of the portable communication device based on a detected radio frequency power coupled to the first transceiver from radio frequency signals transmitted by the second transceiver. A mitigation action is selected from a plurality of mitigation actions based on a magnitude of the quantified electromagnetic isolation. The selected mitigation action is then applied to the second transceiver to adjust at least one radio frequency characteristic of the second transceiver.

Interference mitigation for portable communication device

An antenna for a portable communication device is provided. The antenna comprises an antenna body having an upper section and a lower section with a connection point therebetween. The connection point being configured to: couple the upper and lower sections during normal antenna operation; decouple the upper and lower sections in response to an impact event; and recouple the upper and lower sections after the impact event.

A portable communication device provides improved converged operations through the use of a programmable logic array operating as a coexistence module (CEM) interoperating with different processors, different modems, and an attenuation switch. Interference during converged operation is detected, analyzed, and applicable mitigation is applied, thereby enabling converged communications to be established in a mitigated mode until the interference has been removed.

Portable communication device and method for mitigating interference. One example portable communication device includes a frequency-modulated (FM) communication subsystem, a cellular communication subsystem, a first electronic processor, and a second electronic processor. The FM communication subsystem includes an FM modem and at least one FM antenna. The cellular communication subsystem includes a plurality of cellular antennas, a plurality of antenna tuners, and a cellular modem. The first electronic processor is configured to generate an alert signal responsive to detecting one of an audio signal reception by the FM communication subsystem and an audio signal transmission by the FM communication subsystem. The second electronic processor is configured to receive the alert signal from the first electronic processor. The second electronic processor is also configured to responsively cause the cellular communication subsystem to set substantially constant impedances for the plurality of cellular antennas.

An inductive landing apparatus for an unmanned aerial vehicle and methods of operation. One method includes locating, with a flight controller, an overhead power line. The method includes controlling a flight system communicatively coupled to the flight controller to bring the unmanned aerial vehicle in proximity to the overhead power line. The method includes controlling the flight system to position the unmanned aerial vehicle such that a first inductive clamp and a second inductive clamp of the unmanned aerial vehicle are aligned with the overhead power line. The method includes causing the first and second inductive clamps to open. The method includes causing the first and second inductive clamps to close around the overhead power line. The method includes inductively coupling the first and second inductive clamps to the overhead power line.

A thermal-electrical assembly () provides with improved heat sinking, electrical shielding and electrical grounding. The thermal-electrical assembly is configured using a shield () having a windowed aperture (), a pliable frame () formed of thermally and electrically conductive material having contours () that fit within and are retained by the windowed aperture, and a thermal insert () formed to fit within the pliable frame. The combination of pliable frameand thermal insert () close off the shield () while providing contact areas for dissipating heat from heat generating circuitry or components. Communication devices, such as portable radios having tight space constraints, can incorporate the thermal-electrical assembly () to minimize electrical emissions while maximizing heat dissipation.
