Abstract: Systems, methods, software and apparatus enable providing supplemental audio content to members of a communication group via a group communication service that manages the multiple member user nodes' transmission and receipt of communications between and among the member user nodes. A request for audio content (e.g., from the communication group or a member user node) causes the group communication service to launch a bot node member to locate and deliver the requested audio content. The audio content can be merged with user node communications (e.g., as transmission packets or as streaming audio content). In some implementations each user node includes a wearable push-to-talk end user device linked to a communication device executing a communication application connected to the group communication service.

Abstract: A wireless instrument area network node employs an internal force sensor arrangement to detect user-provided force on the node and initiate a node operation, such as wake the node from a sleep state or low power mode to a more power-hungry awake and processing state. The internal force sensor avoids the need to provide external buttons, a screen, and the like on the surface of the node that could lead to intrusion of fluids, gases, or other unwanted substances into the node. In some embodiments, the internal sensor may include a microswitch that has sufficient sensitivity to detect even a very small amount of deflection resulting from, for example, a hand touch. In some embodiments, the internal sensor may include a piezoelectric sensor that has similarly high deflection sensitivity. Multiple such deflection detectors may be at different angles to one another deployed to provide greater directional coverage for the deflection.
