Abstract: A compressor assembly having a high velocity muffler system which produces a particle-free compressor pump feed while reducing noise output from the compressor assembly during compressing operations. The high velocity muffler system is maintenance-free and comprises an inertia filter. The compressor assembly uses a method for producing a compressor pump feed and reducing noise during compressing operations by processing a gas through the high velocity muffler system which has an inertia filter and a muffler chamber to produce a compressor pump feed which can be compressed by a pump assembly.

Abstract: A method for measuring thermal resistance between a thermal component of an instrument and a consumable includes contacting a known consumable with a thermal component to be tested; driving the thermal component using a periodic sine wave input based on a predetermined interrogation frequency; measuring temperature outputs from a thermal sensor responsive to the periodic sine wave input; multiplying the temperature outputs by a reference signal in phase with the periodic sine wave input and calculating the resultant DC signal component to determine an in-phase component X; multiplying the plurality of temperature outputs by a 90° phase-shifted reference signal and calculating the resultant DC signal component to determine a quadrature, out-of-phase component Y; calculating a phase offset responsive to the periodic sine wave input based on tan?1 (Y/X) or a tan 2(X,Y); and determining a resistance value for the thermal interface using a calibrated resistance-phase offset equation and the calculated phase offset

Abstract: A gate assembly that can include a frame with first and second mounts to mount the gate assembly across a V-door space on a rig floor, a first gate rotationally attached to a left side of the frame, and a second gate rotationally attached to a right side of the frame, such that the first and second gates selectively permit and prevent access through the V-door space. Inner panels of the first and second gates can be configured to automatically open and close in response to a catwalk extending into the V-door space or retracting from the V-door space.

Abstract: Systems and methods for optimal planning and real-time control of energy storage systems for multiple simultaneous applications are provided. Energy storage applications can be analyzed for relevant metrics such as profitability and impact on the functionality of the electric grid, subject to system-wide and energy storage hardware constraints. The optimal amount of storage capacity and the optimal operating strategy can then be derived for each application and be prioritized according to a dispatch stack, which can be statically or dynamically updated according to data forecasts. Embodiments can consist of both planning tools and real-time control algorithms.
