Abstract: Techniques for managing connections in a mesh network that includes multiple provisioners are described. In an example, a computer system receives, from a first device set up as a first provisioner in the mesh network, a first identifier of a third device of the mesh network. The computer system also receives, from a second device set up as a second provisioner in the mesh network, the first identifier of the third device. The computer system generates an association between the third device and the first device based at least in part on a determination that the third device is to be reached exclusively via the first device. The computer system also generates a message about an action to be performed by the third device and sends, based at least in part on the association, the message to the first device.

Abstract: Techniques for managing connections in a mesh network are described. In an example, a device sends, to a plurality of devices of the mesh network, one or more messages requesting an action to be performed by a first device of the mesh network. The device determines, based at least in part on data about the mesh network, that the first device is to be reached via a second device of the mesh network. The second device being a single hop away from the device. The device establishes a peer-to-peer connection with the second device and receives, over the peer-to-peer connection, a response of the first device to the message.

Abstract: In a wireless transmission system, a transmitter sends a plurality of data packets to a receiver. The transmitter identifies channel quality indicators corresponding to properties of a communication channel between the transmitter and the receiver. During operation, the transmitter adjusts one or more parameters that affect the Quality of Service (QoS) of data transmission between the transmitter and receiver to enable data transmission at different quality levels over a range of channel quality levels. In one embodiment, the transmitter sends data packets corresponding to video from a camera to the receiver.

Abstract: A wireless networking method includes placing a master device and at least one peripheral device within proximity of each other. A radio frequency request for proximity pairing is transmitted from the peripheral device to the master device. Radio frequency proximity pairing signals implementing the proximity pairing are transmitted from the master device to the peripheral device. The proximity pairing signals are transmitted with a first level of transmission power. After the proximity pairing is complete, operational signals are transmitted from the master device to the peripheral device. The operational signals are transmitted with a second level of transmission power greater than the first level of transmission power.

Abstract: A wind turbine condition monitoring system and method are disclosed where the wind turbines include a tower, a gearbox coupled to the tower, and turbine blades coupled to the gearbox. The monitoring system includes blade sensors coupled to the blades, a hub node coupled to the gearbox and a controller. The controller is in communication with the hub node and blade sensors, and determines blade positions based on blade sensor readings. The blade sensors and hub node can include multi-axis accelerometers. The controller can wirelessly communicate with the blade sensors directly or through the hub node. Using position information, shadowing areas with obstructed communication can be avoided, node separation can be accounted for to reduce power requirements and/or interference from multiple transmitters can be avoided during node communications.

Abstract: A method of wireless communication includes providing a matrix of trackers. The matrix includes rows and columns of trackers. A number of rows and a number of columns in the matrix is determined. If the number of rows is substantially greater than the number of columns, then vertical sweeping is performed including passing data along each of the columns of trackers to an end tracker in each column. If the number of rows is substantially less than the number of columns, then horizontal sweeping is performed including passing data along each of the rows of trackers to an end tracker in each row. If the number of rows is substantially equal to the number of columns, then diagonal sweeping is performed including passing data diagonally across each of the rows and columns of trackers to an end tracker in each row and each column. The data is passed along the end trackers to a final destination data collector.

Abstract: For each first tracker in a first subset there exists a respective second tracker in a second subset such that a distance between the first tracker and the second tracker is shorter than each distance between the second tracker and each of the other first trackers in the subset by more than a threshold distance. In a first time slot, data is wirelessly transmitted using a same first frequency from each of the first trackers in the subset of the first trackers to the respective second tracker in the subset of the second trackers. In a subsequent time slot, the data is wirelessly transmitted from each of the second trackers in the subset of the second trackers to a final destination data collector.

An actuator signal is sent from the controller to at least one actuator associated with the blades. The sending is in response to the receiving of the transmitted signals. At least one of the blades is actuated dependent upon the actuator signal. The actuating is performed by the at least one actuator. Second measurements of the structural characteristic of each of the blades are repeatedly taken by use of the sensors after the actuating step.
