Abstract: The present invention provides a disposable trumpet valve tube cassette assembly, as well as, a surgical irrigation instrument that includes a probe assembly, a pump, a removable pump cartridge, and a socket. The probe assembly provides passage of fluids for irrigating the body interior and for evacuating matter from the body interior. The pump provides for pumping irrigation fluid through the probe assembly into the body interior. A pump cartridge defines a pumping chamber. Electronic control circuitry includes an electronics controller and a trumpet valve switch interface. The electronics controller includes a pulse generator that generates pulses, the duty cycle of the pulses controlling the speed of the motor. The trumpet valve switch interface is in electronic connection to a switch, the interface providing a signal to the controller.

Abstract: A moist wipe having a web of fibers stabilized as with a suitable binder, and the stabilized, dry web having an anionic surface charge not greater than about 1.2 meq/Kg. A cationic functional agent in an aqueous imbuement is added to the web which is partially adsorbed by the web and a portion of the agent remaining free. Because the anionic surface charge on the substrate is relatively low, there remains in the free aqueous medium a sufficient quantity of the functional agent deliverable to the surface to achieve the desired efficacy. The resulting web will adsorb a limited amount of the cationic functional agent in the aqueous imbuement, and thereby an adequate amount of the agent remains in the solution free of the web for deliverance to the surface, thereby obviating high loadings of the imbuement and the active functional agent.

Abstract: Seals for rotary sealing applications such as the sealing of shafts of rotary drill bits and other equipment such as rotary mud motors used for inshore or offshore oil or gas recovery. The seal may have a U-cup or solid geometry profile including grooves which function to retain fluid for lubricating the surfaces being sealed.

Abstract: A method and self-tuning circuit for tuning vibratory transducers, broadly including electroacoustic speakers and specifically including the speakers of common back-up alarms used for safety reasons on commercial vehicles and heavy equipment. The self-tuning circuit is physically coupled to the transducer's input terminals and operates by comparing the rising and falling edges of one period of a test waveform elicited from the transducer by the application of a test signal having a test frequency. Depending on the results of this comparison, the test frequency is adjusted by predetermined increments upward or downward until the transducer's resonance frequency has been tightly bracketed though not exactly pinpointed.

Abstract: A ventilator control system controls a ventilator pneumatic system in a medical ventilator. The ventilator control system includes a user interface, a memory and a processor. The user interface receives input values from a user for setting one or more breath parameters within a set of breath parameters. The user interface can include a display for displaying the status of the patient's pulmonary system and the set of breath parameters. The memory stores the set of breath parameters after the user has set one or more breath parameters to desired input values. The processor simultaneously adjusts a plurality of controls within a ventilator pneumatic system in response to the set of breath parameters. The user can change or implement new phases, breaths, modes or therapies in seconds such that the therapy delivered to the patient is essentially uninterrupted. Also, a simulator may be provided for predicting the status of the patient's pulmonary system prior to adjusting the plurality of controls.

Abstract: A pneumatic system is provided for a ventilator is provided for controlling inspired and expired patient gas flow during respiratory therapy. The pneumatic system includes a pneumatic circuit for controlling a supply of one or more selected gases to a patient and a disposable patient breathing circuit for isolating exhaled patient gasses from the pneumatic circuit. The pneumatic circuit includes a dual venturi for assisting compression and expansion of a flexible gas reservoir of the patient breathing circuit.

Abstract: An automotive seat belt pretensioner assembly is provided which includes a housing assembly (12) for receiving a cable (18) that is driven by a piston (16) toward an open end (54) of an actuator housing (24) in response to the operation of a pyrotechnic gas generating device (20). A plastic end cap (26) is provided for covering the housing end (54). The cap (26) includes a frangible end wall (54) for permitting passage of an end (46) of the cable (18).
