Abstract: Systems, methods, software and apparatus enable linking of a wearable end user communication device (EUD) to an intermediate communication device (ICD) utilizing optical symbol sequence matching. Optical symbol reference data corresponding to an optical symbol sequence displayed on the EUD is obtained from the EUD by the ICD. Optical symbol input data is also acquired by the ICD (e.g., via user inputs, EUD device proximity data, image acquisition). The devices are linked if the optical symbol reference data and optical symbol input data match. The optical symbol reference data can be displayed, allowing user confirmation of a match with the optical symbol sequence displayed on the EUD. An ICD user interface touchscreen can present users with selectable color inputs to replicate the optical symbol sequence displayed on the EUD, for example using an LED array. Communications between the devices before and after linking can utilize Bluetooth low energy.

Abstract: Systems, methods, software and apparatus that enable dynamic audio transducer control include obtaining attribute information relating to multiple communication nodes that are communication node group members. A group management system or other computing system receives attribute information from two or more of the communication nodes and determines settings for one or more audio transducers (e.g., speakers and microphones) in the group's communication nodes based on the attribute information. An audio transducer command is transmitted to or imposed on one or more of the nodes. Attribute information can include node attributes and/or changes to attributes. Audio transducer commands transmitted or otherwise imposed on nodes can include muting and unmuting commands, as well as setting volume levels and other audio settings associated with a node's operation.

Abstract: Systems, methods, software and apparatus enable device to device grouping of personal communication nodes include managing a communication node group having communication node members. Attribute information from the communication nodes is provided to a management system that defines communication group membership based on the received attribute information. The management system transmits group membership status notifications to the communication nodes. Membership status controls a node's participation in group communications. Attribute information can include changes (such as dynamic changes) in one or more communication node attributes, such as location, proximity to other communication nodes, speed, etc.
