Patent number: 7802571Abstract: Method and apparatus for controlling a ventilator are described. The invention can be used to control mechanical ventilators as well as respiratory assist devices such as CPAP machines. The apparatus receives input data indicative of patient's oxygen level. A controller determines PEEP, or CPAP, and FIO2, on the basis of data indicative of the patient's oxygen level. In an alternative embodiment, the apparatus further receives input data indicative of patient's carbon dioxide levels, respiratory elastance and airway resistance, and barometric pressure. The controller further utilizes the said input data to determine the optimal values of tidal volume and breathing frequency for a next breath of the patient, and uses the respiratory elastance and airway resistance data to determine any necessary adjustments in the I:E ratio. The controller also applies safety rules, detects and corrects artifacts, and generates warning signals when needed.Type: GrantFiled: September 7, 2004Date of Patent: September 28, 2010Inventor: Fleur T.

Patent number: 7793656Abstract: A swim and skin-dive snorkel for providing positive end-expiratory pressure for pressure-balanced exhalation. The snorkel may include inhalation and exhalation conduits. Air can be exhaled into a chamber and released when exhalation pressure within the chamber exceeds a threshold pressure. The threshold pressure that must be overcome to achieve exhalation may be balanced against the compressive forces of the ambient water pressure acting against the user's chest and lungs, which may greatly reduce the resting expiratory flow rate, the minute respiratory rate, and therefore the overall work of breathing. The exhalation pressure may be linearly matched to the ambient water pressure as a function of dive depth, thereby discouraging exhalation while diving. A purge valve may also be placed at the lower aspect of the snorkel.Type: GrantFiled: June 3, 2003Date of Patent: September 14, 2010Assignee: Lifetime Products, Inc.Inventor: Mark Johnson

Patent number: 7779831Abstract: A nebulizer includes a piezoelectric transducer for aerosolizing a drug solution in a disposable cup module disposed above the transducer. Acoustic waves generated by the transducer propagate sequentially through transmitting medium, a first barrier, coupling medium, and a second barrier that forms part of the cup module, and into the interior of the cup module. The transducer at least partially comprises silver. The silver fluidly contacts the transmitting medium to discourage bacteria growth in the transmitting medium. The device includes electronics components that drive the transducer and measure an electrical characteristic associated with the transducer during operation. The electronics components measure changes in the electrical characteristic to determine when the drug solution level falls below a predetermined threshold, and deactivates the device accordingly.Type: GrantFiled: April 19, 2007Date of Patent: August 24, 2010Assignee: RIC Investments, LLCInventors: Dirk Von Hollen, Eric A.

Patent number: 7770630Abstract: A modular capillary pump loop (CPL) cooling system and associated components. The modular CPL cooling system transfers heat from high-power circuit components, such as microprocessors disposed within computer chassis, to other locations within or external to the chassis, where the heat can be more easily removed. In various embodiments, the CPL cooling system includes one or more evaporators connected to one or more condensers via flexible liquid transport and vapor transport lines. A wicking structure, such as a volume of sintered copper, is disposed within each condenser. The wicking structure draws working fluid (e.g., water) in a liquid state into the evaporator based on a capillary mechanism and a pressure differential across a meniscus/vapor interface on an upper surface of the wicking structure. As the liquid meniscus is evaporated, additional fluid is drawn into the evaporator. The working fluid is then condensed back into a liquid in the condenser.Type: GrantFiled: August 26, 2003Date of Patent: August 10, 2010Assignee: Intel CorporationInventors: Jason B. Chesser, Barrett M. Faneuf, Stephen W. Montgomery
