Inventor: GOEL RAKESH
IPC: F24F11/00
Filed: 2016-01-26
Abstract: Systems and methods are presented for improving stabilization of a heating, ventilating, and air conditioning (HVAC) system. More specifically, the systems and methods include a heat-flow modulator for regulating an exchange of thermal energy between a flow of refrigerant and a sensory bulb. The exchange of thermal energy allows an expansion valve to respond to a refrigerant temperature using an actuator, which is coupled to the sensory bulb. The heat-flow modulator is formed of a body that includes a first contact surface and a second contact surface.  The first contact surface is thermally-coupled to a suction line of the HVAC  system, which conveys the flow of refrigerant. The second contact surface is thermally-coupled to the sensory bulb. Other systems and methods are presented.

Title: Blood control catheter valve employing actuator with flexible retention arms
Inventor: HARDING WESTON F
IPC: A61M39/06
Filed: 2014-07-17
Abstract: The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for passing through a septum (301) to open the blood control catheter valve. The actuator includes flexible retention arms (201) positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve.
