A wireless edge device is operable in a wireless network and configured to communicate with other wireless devices in the wireless network. The wireless edge device includes a processor configured to receive an input to switch from a low power consumption normal operation mode to a site survey mode, a transceiver configured to (i) transmit data packets periodically or asynchronously to a wireless device of the wireless network, and (ii) receive the data packets returned by the wireless device, and a visual indicator. The processor is further configured to evaluate quality and/or reliability of the received data packets, to provide a signal to the visual indicator indicative of signal strength at the wireless edge device based on the evaluation of quality and/or reliability of the received data packets, and to switch from the site survey mode to the low power consumption normal operation mode after a predetermined time.

A sensor may include a base, an accelerometer rigidly coupled with the base and centered over said base, a circuit arrangement electrically coupled with the accelerometer, and a battery rigidly held in contact with the circuit arrangement and centered over said accelerometer and said base. The base is configured to be secured to a host structure, and the circuit arrangement is configured to receive signals from the accelerometer.

An antenna assembly including an antenna, an antenna cable, a bendable structure, a housing interface, a first protection section and a second protection section. The bendable structure is a malleable material that remains in a bent position when bent. The first protection section covers the antenna and provides a weatherproof cover over the antenna. The housing interface mounts to a housing and covers the antenna cable in an area of the antenna cable adapted to enter the housing and the housing interface prior to entrance providing a weatherproof cover over the area of the antenna cable adapted to enter the housing. The second protection section is overmolded over a portion of the housing interface, the antenna cable, the bendable structure and a portion of the first protection. The second protection section is a flexible material.

Flow sensor includes a housing having a chamber and a tube extending therefrom. Static and stagnation pressure ports are located along the tube and open in different directions about a periphery. A first conduit fluidly couples the static pressure port to the chamber, and a first pressure sensor senses the fluid pressure in the chamber. A differential pressure sensor has a first port and a second port in the chamber. The first port senses the fluid pressure in the chamber, and a second conduit fluidly couples the stagnation pressure port with the second port. The second port is more exposed to fluid flow through the pipe relative to the first port. Fluid flow rate through the pipe is determinable based on static fluid pressure sensed by the first pressure sensor, differential pressure measured by the differential pressure sensor, density of fluid in the pipe, and diameter of the pipe.

A source node in a network accesses information associated with a set of available transmission states. The source node selects a first transmission state from the set of available transmission states. The source node evaluates a metric associated with transmitting the data. The source node determines whether the metric is below a threshold value. Based on determining that the metric is below the threshold value, the source node selects a second transmission state from the set of available transmission states, the second transmission state being different from the first transmission state. The source node transmits data using the second transmission state.

Channel adaptation in sensor networks

An energy harvesting device utilizing a monolithic, mesoscale, single-degree-of-freedom inertial based resonator in which the support structure, beam-spring, and proof mass are a single component without joints, bonds, or fasteners. Frequency tuning features include holes in the proof mass in which mass can be added to change the devices resonance frequency as well as levers which add curvature to the beam-spring system and adjust system stiffness. Robustness is increase by designing the resonator to exhibit nonlinear behavior such that its power density is maximized for low vibration amplitudes and minimized for high amplitudes. The device structural resonance modes are designed to be much higher than the resonators proof mass-spring resonance frequency. Electromechanical transducers are used to convert the resonators mechanical energy to electrical energy. Electrical circuitry is included to extract and condition the electrical charge.

A improved method of monitoring a structure by mounting a sensor within a cavity of the structure to measure at least one of strain experienced by the structure and vibration experience by the structure. Mounting a wireless communication unit mounted within the structure and connecting the wireless communication unit to the sensor to receive data from the sensor and transmit the data to a receiver outside the structure. Mounting a power supply within the structure and connecting the power supply to the sensor and the wireless communication unit to supply necessary electrical power to the sensor and the communication unit.

Internal structural monitoring system

An internal structural monitoring system for a structure that includes a sensor mounted within the structure to measure at least one of strain experienced by the structure and vibration experience by the structure. It includes a first system support mounted and second system support mounted in the structure, where the first system and the second system support are mounted in the structure such that the sensor is between the first system support and the second system support to hold the sensor in position so that the sensor senses at least one of strain and vibration. It includes a wireless communication unit mounted within the structure, the wireless communication unit connected to the sensor to receive data from the sensor and transmit the data to a receiver outside the structure. It includes a power supply mounted within the structure to supply necessary electrical power to the sensor and the communication unit.
