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 and method receive a selection input and an action input from different sets of sensors. The inputs are associated with a device, an action is selected for the device, and a control signal is sent to the device to operate the device. The sensors may receive signals including voice commands, gestures, and location information. The system and method may also be applied to select multiple devices and perform actions on each of the devices.

Abstract: Systems and methods for the periodic creation of wireless mesh networks are disclosed. In order to save power the nodes in the mesh network may periodically switch from being in a broadcast mode and a skip cycle. When in the broadcast mode the node may cycle broadcasting new IDs in order to prevent spoofing.

Abstract: A system and apparatus for assessing whether a personnel has complied with sanitation protocols. The system may incorporate wearable tags on each personnel which can communicate with a mesh network to confirm presence of the personnel. In an embodiment, a soap dispenser may be part of the mesh network such that, when the dispenser is activated, a personnel's presence is detected and recorded.

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 provides a system of intelligent lights together with control devices and sensors communicating over a wireless network, with methods to allow the lights to take actions based on logical combinations of events generated by other devices. The lights can function autonomously as they have built-in functions of logic processing, storage and wireless communications which allow them to receive events and take actions according to the stored logic configuration data. Complete freedom in the grouping of lights as well as association of control devices and sensors to each individual lights is enabled by this system architecture. Seamless communication coverage is enabled by a wireless protocol that allows the light to form a mesh network.
