Abstract: The present invention discloses a noise-vibration (NV) microphone stand for holding an NV microphone a predetermined distance from a surface that the NV microphone stand is attached to. The NV microphone stand can include a rod having an attachment end that is operable to attach to the surface to be tested and with the rod extending away from the surface. In addition, an arm can be attached to and extend from the rod, the arm having an NV microphone bracket spaced apart from the rod. The NV microphone bracket can have an opening that is dimensioned for the NV microphone to slide therewithin, the opening having a plurality of friction wiper blades that come into contact with the NV microphone when it slides within the bracket.

Abstract: A coolant flow measurement device includes a coolant flow circuit, a cooling system, a purge system, a variable speed fluid pump, a differential pressure gage and a primary flow meter. The coolant flow circuit may be attached to a an HVAC system of the vehicle such that coolant may be circulated through the HVAC system of the vehicle. The cooling system may cool the coolant in the coolant flow circuit. The purge system may be used to purge air from the coolant flow circuit. The variable speed fluid pump may be operable to balance the fluid pressure between the device inlet and the device outlet. The primary flow meter may be operable to measure the coolant flow in the coolant flow circuit. The differential pressure gage measures a pressure differential between the device inlet and the device outlet.

Abstract: An anti-leak adaptor for use in a vehicle during an air conditioning system evaluation includes a cylindrically shaped adaptor body having a first end and a second end. A central passageway extends between an opening in the first end to an opening in the second end. The first end includes a guide portion and a threaded portion that is adjacent the guide portion. A knob is positioned on a mid-portion of the adaptor body, and the knob is operatively connected to a plunger disposed within the central passageway in the adaptor body and oriented longitudinally towards the opening in the first end. A fitting is connected to the second end of the adaptor body for receiving a sensing means.

Abstract: A tube coupling having a ring seal with a U-shaped cross section that is encapsulated in a socket member when engaged and compressed by the free plug end of a tube and sealingly contacts the end of the tube at the radial end surface and inner and outer diameter wall surfaces thereof and also three surrounding surfaces of the socket member.
