Abstract: A pumping system for assisting a patient's heart includes a blood pump disposed outside the patient's body and having an inlet and an outlet. An inlet cannula is configured for insertion percutaneously into the vascular system of the patient, and in fluid communication with the blood pump inlet to provide blood to the blood pump. An outlet perfusion cannula is configured for insertion percutaneously into the vascular system of the patient, and in fluid communication with the blood pump outlet to provide blood to the patient's vascular system. A control system is provided to control the blood pump and includes at least two control units for redundant control of the blood pump. Each control unit includes a watchdog for monitoring the control unit. A variation of the pumping system includes a bidirectional cannula for insertion percutaneously into the vascular system of the patient and to extend into the patient's heart.

Abstract: An automatic fill system for a beverage dispenser includes a sensor system for monitoring the beverage level in the dispenser. The sensors are wired in series with a level control board mounted inside the frame of the beverage dispenser. Sensing points are connected in an electrical circuit for maintaining the proper water to beverage concentrate ratio in the mixing hopper of the beverage dispenser. Resistance in the circuit is monitored so that when the resistance in the circuit reaches a predetermined value, a relay and solenoid open to divert water to the mixing hopper for mixing with the beverage concentrate. Sensors in the hopper shut off the dispenser when the beverage level in the hopper exceeds maximum and minimum levels.

Abstract: Aspects for more reliable particle removal from a semiconductor processing chamber following a chamber wet clean are described. With the present invention, an improved particle removal following wet cleans of semiconductor processing chambers occurs. The present invention creates a turbulent gas flow in a chamber in order to more thoroughly remove particles from the chamber, including those that the wet clean procedures cannot reach. In a straightforward and efficient manner, the turbulent gas flow is created by providing gas in both an upper and lower portion of the chamber substantially simultaneously, including the advantageous use of the backside helium available to chamber processing.

Abstract: A system for closing together a first side of a sternum and a second side of the sternum of a patient. The system includes a first grommet to be disposed in the first side. The system includes a second grommet adapted to be disposed in the second side. The system includes a mechanism for placing a grommet into the sternum. The placing mechanism is adapted to hold the grommet for placement in the sternum. The system includes a first wire suture for insertion through the first and second grommets. The system includes a stop mechanism for allowing the placing mechanism to place a grommet into the sternum only in a desired location of the patient and any other portion of the patient is protected from damage by the placing mechanism during operation. A grommet. An approximator. A drill stop mechanism. A placement tool. A method of threading a wire suture through a hole in a sternum. A method of bringing together a first side of a sternum and a second side of the sternum.

Abstract: The present invention provides an improved frozen beverage dispenser overcoming the disadvantages of the prior art noted above. Not only is the beverage dispenser relatively simple to construct and maintain, but it also provides an exceptionally fast freeze down time and accurate monitoring and control of the thickness of the slush dispensed from the beverage dispenser of the invention. The components of the beverage dispenser of the invention are housed within a compact housing incorporating solid state design with few mechanical moving parts. The closed loop system includes an evaporator, heat exchanger, condenser, compressor, and a filter/dryer. A tank feed system directs the beverage mix to a cylindrical mixing chamber having a rotatable beater bar located therein. The beater bar is coupled to a direct drive control system which monitors and controls the thickness of the slush formed in the mixing cylinder.
