Abstract: An apparatus including: a housing configured for installation in a landfill; a differential pressure sensor and at least one gas sensor in the housing; and a first valve configured to control landfill gas (LFG) flow to the at least one gas sensor, wherein the first valve is configured to open when the differential pressure sensor detects a selected pressure difference or pressure difference change between the atmospheric air pressure and the LFG pressure.

Abstract: A utility pole monitoring device comprising a body adapted to couple to a utility pole, a vibration device arranged on the body and configured to generate vibrations on or in the utility pole, a sensor arranged on the body for measuring the vibrations within the utility pole generated by the vibration device, and a controller for providing an initialization signal to the vibration device, and receive measured data from the sensor.

Abstract: The present invention is a wear sensing and monitoring system including: at least one sensor node, and wireless communication means, and a gateway node, and a remote monitoring and management node, wherein the wireless communication means are adapted to enable the at least one sensor node to have at least one-way wireless communication from the node to the gateway node. The gateway node is adapted to have at least one way wired or wireless communication from the gateway node to the remote monitoring and management node. Note that the two nodes may be included in the one device.

Abstract: A method of operating a multicopter comprising a body and n thrusters, each thruster independently actuated to vector thrust angularly relative to the body about at least a first axis, the method comprising modelling dynamics of the multicoptor with a mathematical model comprising coupled, non-linear combinations of thruster variables, decoupling the mathematical model into linear combinations of thruster control variables, sensing at least one characteristic of multicopter dynamics, comparing the sensed data with corresponding target characteristic(s), computing adjustments in thruster control variables for reducing the difference between the sensed data and the target characteristic(s) according to a control algorithm, and actuating each thruster according to the computed thruster control variables to converge the multicopter towards the target characteristic(s), wherein the control algorithm is based on the decoupled mathematical model such that each thruster control variable can be adjusted independently.

Abstract: A sleeping bag including an internal bag-temperature sensor located in the sleeping bag to measure an internal air temperature in the sleeping bag, and a movement sensor located in or on the sleeping bag to measure movement of the sleeping bag.
