Abstract: A method of transmitting a block from a bridge to a mesh network includes transmitting the block to at least a first node of a plurality of nodes, for distribution through the mesh network. The block includes a plurality of packets. The bridge receives, from the plurality of nodes, a plurality of status packets. Each status packet indicates reception status of the plurality of packets at a respective node of the plurality of nodes. The bridge selects at least a first packet of the plurality of packets for retransmission to the mesh network, based on the status packets. The bridge generates a retransmission block including at least the first packet. The first packet is included in the retransmission block a number of times based on the status packets. The bridge transmits the retransmission block to at least the first node, for distribution of the retransmission block through the mesh network.

Abstract: A position tracking system for Tags to collect relative proximity to other Tags using received signal strength, with methods to reduce power consumption with controlled degradation in overall system performance such as location accuracy and frequency of location updates. Configurable parameters for control of tag functions facilitate performance tradeoffs against application requirements. System architecture using mobile phone and gateway for uploading data enables efficient upload of tag data without user intervention. Applications of the disclosure include self-quarantine, contact tracing, mother-infant pairing, location history tracking, and personnel-asset usage monitoring.

Abstract: In some configurations, the method of operating a system with dynamic wireless network topology with reduced spectrum flooding involve scanning with a first device in mesh network for beacon packets from other devices in the mesh network during a random back off period. In response to the first device not receiving a beacon packet from the other devices during the random back off period, the first device initiates an election protocol by sending an election protocol packet with its unique election protocol identifier to the other devices. In response to receiving a beacon packet from a second device, the first device stores the unique node identifier, assigns the second device as a leader node device, retransmits the unique node identifier of the second device and leader node information in a protocol packet. A command packet is communicated through the mesh network by way of at least one leader node device.

Abstract: A system integrates a wireless controller into a linear, alternating current-only driver. The system utilizes a light emitting diode driver to maintain a constant current to a light emitting diode when a current controller is operated by a pulse width modulated signal. The pulse width modulated signal to one or more light emitting diode circuits may be modified to reduce flicker, color mix, and temperature tune.

Abstract: This disclosure relates to systems and methods for accessing a device using a paired device in its proximity. In one embodiment, a resource sharing method is disclosed, comprising: obtaining a proximal device identifier associated with a proximal device; identifying a proximal device profile associated with the proximal device identifier; retrieving access privilege data stored in the proximal device profile; generating, via a processor, user interface data based on the access privilege data; and providing the user interface data for display.

Abstract: A method, non-transitory computer readable medium and device that manage interactive content include initiating at least one widget application. A list of available interactive content previously received and stored from a broadcast stream is received based on the initiated widget application. An item of interactive content is selected from the received list of available interactive content. The selected item of interactive content is received and provided. Another method, non-transitory computer readable medium and device that processes interactive content includes obtaining interactive content from one or more content providers. One of one or more content types for the obtained interactive content is identified and metadata associated with the identified content type is identified. The obtained interactive content is transformed into a standard format based on the identified content type and the metadata associated with the obtained interactive content.
