  • Autonomous robot-assisted indoor wireless coverage characterization platform
    Patent number: 9668146
    Abstract: A wireless coverage characterization platform uses an autonomous vehicle or robot, such as an unmanned aerial vehicle or other small robot, to autonomously collect key wireless coverage parameters for an indoor environment. One or more vehicles or robots are equipped with integrated simultaneous localization and mapping sensors as well as wireless signal measurement sensors. As a vehicle traverses the indoor environment, on-board processing components process the sensor measurement data to simultaneously build an indoor map of the environment and to learn the wireless coverage characteristics of the environment incrementally. The vehicle's navigation system guides the vehicle through the environment based on the sensor measurements and the learned indoor map until a complete map of the wireless signal strength at all locations throughout the environment is obtained.

  • Well testing apparatus and methods for measuring the properties and performance of oil and gas wells
    Patent number: 9612360
    Abstract: To determine properties of multiple oil and gas wells, oscillations at different test frequencies are applied to the flow rate and/or pressure of multiple wells. Measurements of flow rate and/or pressure and temperature in flows downstream of a production header of the multiple wells are then obtained. Such measurements from the flows of the multiple wells are subjected to a frequency analysis of the pressure, flow rate and/or temperature measurements to determine pressure, flow rate and/or temperature variations induced by the applied oscillations. Properties of the different wells of the multiple wells based on the results of the frequency analysis are thus determined.

  • Apparatus and method for priming a molten metal filter
    Patent number: 9605332
    Abstract: An apparatus and method are described for effectively priming a non-electrically conductive filter for removal of solid inclusions from liquid metal. In one embodiment, the ceramic filter media is surrounded by a low frequency induction coil (1-60 Hz) with its axis aligned in the direction of the net metal flow. The coil is positioned to enhance the heating of any metal frozen onto, or in the pores of, the filter element. In one embodiment, the coil is positioned in order to generate Lorentz forces, which act to cause heated metal to impinge on the upper surface of the filter element, enhancing the priming action. Once a filter equipped with such a coil has been primed, it can be kept hot or reheated, and subsequently reused during several batch tapping sequences.
