Patent number: 11444805Abstract: 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.Type: GrantFiled: August 6, 2019Date of Patent: September 13, 2022Assignee: WISILICA INC.Inventors: Francis Antony, Suresh Singamsetty, Dennis Ching Chung Kwan, Manu Velayudhan

Patent number: 10785672Abstract: 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.Type: GrantFiled: September 11, 2018Date of Patent: September 22, 2020Assignee: WiSilica Inc.Inventors: Dennis Ching Chung Kwan, Suresh Kumar Singamsetty

Patent number: 10491416Abstract: 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.Type: GrantFiled: October 19, 2015Date of Patent: November 26, 2019Assignee: WiSilica Inc.Inventors: Suresh Kumar Singamsetty, Dennis Ching Chung Kwan

Patent number: 10492280Abstract: 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.Type: GrantFiled: October 12, 2018Date of Patent: November 26, 2019Assignee: WiSilica Inc.Inventors: Dennis Ching Chung Kwan, Suresh Kumar Singamsetty, Francis Antony

Patent number: 10405264Abstract: A pairing scheme may add devices to a mesh network automatically. Assuming that at least one device is already part of the mesh network, this scheme may allow devices that have not been paired yet to be automatically added to the mesh, eliminating manual pairing processes. When a new device is powered on, it may broadcast a connectable advertisement packet. The payload of this packet may be secure and not understood by the recipient device. Rather, only a server may have a copy of the device key, and can thus decrypt the advertising packet. The server sends a packet back with a network key and information, and the device then becomes part of the network.Type: GrantFiled: October 17, 2017Date of Patent: September 3, 2019Assignee: WiSilica Inc.Inventors: Dennis Kwan, Suresh Kumar Singamsetty

Patent number: 10313861Abstract: Communication may be enabled between mobile devices (i.e., controllers) and Internet of Things (IoT) devices by sending connectionless commands from a controller to an IoT device, or sending connectionless commands from a controller to more than one IoT devices, at the same time. One or more commands may be sent from a controller to one or more nodes that form a network, with the nodes relaying messages to each other via connectionless data packets. This may allow for connectionless command relay from the controller to any node within the network. By sending commands through connectionless data packets, one or more controllers may control one or more nodes at the same time. Furthermore, a single controller may directly send one or more commands to a group of nodes at the same time.Type: GrantFiled: September 13, 2017Date of Patent: June 4, 2019Assignee: WiSilica Inc.Inventors: Dennis Kwan, Suresh Kumar Singamsetty
