Abstract: A HVACR protection system can include a pressure sensor to sense pressure within a refrigerant line coupled to a compressor; a timer; and a protection system controller. A compressor controller in communication with the protection system controller can control operation of the compressor and disable the compressor until successful completion of a vacuum test of the refrigerant line. The vacuum test can initiate upon the pressure sensor sensing the pressure being less than or equal to a vacuum test pressure, at which point the timer begins timing for a vacuum test time period. The vacuum test is successfully completed upon expiration of the vacuum test time period with the pressure remaining less than or equal to the vacuum test pressure for the vacuum test time period. The protection system controller can enable the compressor controller to operate the compressor upon successful completion of the vacuum test.

Abstract: A deformable mirror is provided that can include a mirror assembly having a reflective face sheet with a reflective surface on a front side of the reflective face sheet. The mirror assembly can also comprise one or more ferrous materials positioned within and making up or forming, in part, the mirror assembly. The deformable mirror can also include one or more electromagnets operable to generate a magnetic field that acts on the ferrous materials to deform the reflective face sheet.

Abstract: A deformable mirror can include a reservoir containing a ferrofluid. The deformable mirror can also include a reflective face sheet covering a front side of the reservoir such that a back side of the reflective face sheet is exposed to the ferrofluid. The reflective face sheet can have a reflective surface on a front side of the reflective face sheet opposite the back side. The reflective face sheet can have a non-uniform thickness between the front and back sides of the reflective face sheet to provide stiffness for the reflective face sheet. In addition, the deformable mirror can include one or more electromagnets operable to generate a magnetic field that acts on the ferrofluid to deform the reflective face sheet. A deformable mirror system can further include a control system operably coupled to the one or more electromagnets to control the magnetic field and thereby a deformation of the reflective face sheet.

Abstract: A heating, ventilation, air conditioning, and refrigeration (HVACR) protection system can include a pressure sensor operable to sense a pressure within a refrigerant line operably coupled to a compressor; a timer; and a protection system controller. The protection system controller can be in communication with the pressure sensor, the timer, and a compressor controller operable to control operation of the compressor. The protection system controller can disable the compressor controller from operating the compressor until successful completion of a vacuum test of at least the refrigerant line. The protection system controller can be configured to initiate the vacuum test upon the pressure sensor sensing the pressure of the refrigerant line less than or equal to a vacuum test pressure, at which point the timer begins timing for a vacuum test time period.

Abstract: A microsection sample stabilizer for aligning and stabilizing a microsection sample for microscopic inspection includes a frame including a base and at least one leveling portion supported by the base. The at least one leveling portion can define a viewing window for a microscope. The microsection sample stabilizer includes an interior region within the frame, and at least one compliant device operable within the interior region of the frame and operable to be supported by the base. The compliant device receives and supports the microsection sample, and biases the microsection sample against the at least one leveling portion of the frame to stabilize the microsection sample, such that an examination plane surface of the microsection sample is aligned and viewable through the viewing window by the microscope.

Abstract: A method for testing for the presence of a trivalent chromium conversion coating on a metal substrate is provided. According to one embodiment, the method comprises contacting a surface of the metal substrate with at least one solvent to generate a test solution, adding an indicator capable of detecting zirconium to the test solution in an amount sufficient to induce a color change of the test solution if zirconium is present in the test solution, and determining whether a color change indicating the presence of the conversion coating occurs in the test solution.

Abstract: A system includes a component inspection system having a radiation source configured to generate radiation and a radiation detector configured to detect the radiation after the radiation passes through components to be inspected. The system also includes a fixture configured to receive multiple reels that are each configured to receive a tape in or on which the components are located. The fixture includes a base configured to be secured to a support, a shaft, one or more motors mounted to the shaft and configured to rotate the reels, and one or more joints coupling the shaft and base. The one or more joints are configured to allow (i) rotation of the shaft about a longitudinal axis of the shaft to change an orientation of the shaft with respect to the base and (ii) rotation of the shaft to change a direction at which the shaft extends away from the base.
