US Patent 9652593 Search and retrieval of real-time terminal states maintained using a terminal state database

A system for providing a device independent communication layer for connecting two remote telemedicine terminal devices at least partly based on searching a terminal state database for device independent, real-time terminal states of remote telemedicine terminal devices, comprising: one or more databases for storing data entries with data indicative of terminal states of a plurality of first remote telemedicine terminal devices; a tracking module configured for detection of real-time terminal states of the plurality of first remote telemedicine terminal devices for communication with the system; a terminal state aggregation module configured to collect real-time indications of terminal states; a search module for searching the data entries and the stored data; a device independent communication layer for coordinating communications between remote telemedicine terminal devices; and a device connection module for establishing connections, over the device independent communication layer, between one remote telemedicine terminal device and another remote telemedicine terminal device.
