Abstract: An illustrative modular manifold system includes, among other things, two or more modular pump manifolds, a low-pressure header, and a main high-pressure manifold. Modular pump manifolds may include a low-pressure manifold for supplying fracturing fluid or water to pumps, a high-pressure manifold for supplying fracturing fluid or water to one or more wells and a bleed-off/prime-up manifold. Each modular pump manifold of the modular manifold system is configured to be fluidly isolatable from the other modular pump manifolds. Each isolated modular pump manifold is configured to be flushed with water, bled off and primed up independently of the other modular pump manifolds. After the bleed off, maintenance procedures may be performed on pumps associated with the isolated modular pump manifold. The modular pump manifolds that are not isolated may continue in active fracing stage operations while a modular pump manifold is isolated.

Abstract: A method of foreign object detection for a wireless power transmitter. The method includes determining a vector impedance of a near-field communication (NFC) coil with an NFC chip. The determined vector impedance includes an impedance amplitude component and an impedance phase component. The impedance amplitude component and the impedance phase component are compared to a baseline impedance amplitude and a baseline impedance phase. A determination as to whether an object is present within an inductive charging area of the wireless power transmitter is made when a difference between the determined vector impedance, and the baseline impedance amplitude and the baseline impedance phase, exceeds a delta threshold. A ping signal is generated with a charging source coil when the object is determined to be present. A foreign object is detected based on whether a response signal to the ping signal is received from the object.
