Abstract: A system for estimating space and budgeting requirements for real estate applications provides remote access to a user over a network so the user can receive real estate space and budgeting estimate in real time through a graphical user interface. A processor receives via a graphical user interface the user's select test fit parameters and the user's select property record of a subject property. The processor automatically generates a leasing cost estimate and a construction cost estimate based on the user's select test fit parameters and the user's select subject property record. The processor automatically generates a proposed layout of a floor plan based on the user's select test fit parameters and the user's select subject property record. The processor transmits the generated leasing cost estimate, the generated construction cost estimate, and the generated proposed layout of the floor plan for display in the graphical user interface.

Abstract: A system and method is described for detecting abnormal contacts and misalignment of end effector of a robot arm during robotic arm operation. A contact shock transients sensing unit detects signals on the robot arm and generates alarms, identifies the location of the contact shock transients in the robot arm operation, and controls robot arm operation to prevent further damage to the robot arm and articles handled by the robot arm.

Abstract: In a laser-produced plasma (LPP) extreme ultraviolet (EUV) system, laser pulses are used to produce EUV light. To determine the energy of individual laser pulses, a photoelectromagnetic (PEM) detector is calibrated to a power meter using a calibration coefficient. When measuring a unitary laser beam comprising pulses of a single wavelength, the calibration coefficient is calculated based on a burst of the pulses. A combined laser beam has main pulses of a first wavelength alternating with pre-pulses pulses of a second wavelength. To calculate the energy of the main pulses in the combined laser beam, the calibration coefficient calculated for a unitary laser beam of the main pulses is used. To calculate the energy of the pre-pulses in the combined laser beam, a new calibration coefficient is calculated. When the calculated energy values drift beyond a pre-defined threshold, the calibration coefficients are recalculated.

Abstract: A check valve is provided that includes a valve housing that has a side wall and a flow path therethrough, the side wall defining the flow path. The flow path includes an inlet, an outlet, and a centerline extending between the inlet and the outlet. At least one control member is positioned in the flow path and movable between a first position, wherein fluid flow through the valve housing is substantially prohibited and a second position wherein fluid flow is permitted. The side wall includes a stop configured to limit movement of the at least one control member at a pre-determined stop angle relative to the flow path centerline.
