    Abstract: Systems for aiding emergency responders are described. An exemplary system may include a primary device and a secondary device. The primary device may be configured to provide audio communication between the primary device and one or more of the plurality of secondary devices along a wireless communication path. The primary device may be configured to compress audio communication for transmission over a low bitrate band. The plurality of secondary devices may be configured as a network where each of the devices is configured to communicate with at least two other secondary devices. The secondary devices may also be configured to receive audio communication from the primary device and automatically transmit the received audio communication to one or more other of the secondary devices.

    Abstract: Various arrangements for monitoring and mitigating infrared (IR) interference from a display device are presented. IR emissions from a display device are measured the IR signaling characteristics may be adjusted to mitigate interference from the emissions. Calibration methods may be used determine display emission characteristics by displaying test patterns and video clips. Characteristics of the display patterns and video clips may be correlated to high IR emissions.
