Patent number: 7275502Abstract: A portable animal containment device for confining an animal to a defined area. The portable animal containment device includes a flat and a correction unit. The flat is adapted to be portable and defines the area within which an animal is confined. The flat has an associated presence detector for detecting whether the animal is occupying the flat. When the presence detector indicates that the animal is not occupying the flat, a signal is transmitted to the correction unit by way of wireless communication. The correction unit is carried by the animal and administers a stimulus to the animal when the correction unit receives the signal from the transmitter. Consequently, when the animal moves beyond the boundary defined by the flat, it receives a stimulus, which encourages the animal to remain in the flat.Type: GrantFiled: December 6, 2005Date of Patent: October 2, 2007Assignee: Radio Systems CorporationInventors: Randal D.

Patent number: 7275519Abstract: At the time of startup of an engine having an in-cylinder injector and an intake manifold injector, a risk of pre-ignition during the first-time compression stroke is determined based on a rotational angle of a crankshaft at the time of previous engine stop.

Patent number: 7275539Abstract: A wick arrangement for an anesthetic evaporator includes a wick with a carrier material (2) that is essentially impermeable to gas provided with wick material (3, 4) on both sides. A great path length is provided for saturating the gas with anesthetic vapor in the smallest possible installation volume by providing flow channels such as helical flow channels (10, 11) extending helically on both sides of the wick. The gas flow is led in counterflow in the flow channels (10, 11) by a housing (9).Type: GrantFiled: April 24, 2002Date of Patent: October 2, 2007Assignee: Dräger Medical AG & Co.

Patent number: 7275541Abstract: A breathing circuit comprising first and second conduits, wherein at least one of the conduits is a non-conventional conduit. In an embodiment, a multilumen unilimb breathing circuit has first and second conduits, wherein when the proximal ends of said first and second conduits are each connected to an inlet and outlet fitting, respectively, axial extension or contraction of the second conduit causes a corresponding axial extension or contraction of the first conduit. In an embodiment, at least one of said conduits is coiled. In another embodiment, a coiled conduit is contained within an outer flexible conduit that is axially extendable and compressible, forming a unilimb, multilumen respiratory circuit. The outer flexible conduit may be pleated to provide for non-rebounding axial extension and contraction. The multilumen respiratory circuit can provide a variable rebreathing volume.Type: GrantFiled: September 16, 2004Date of Patent: October 2, 2007Assignee: F-Concepts LLCInventors: Atsuo F. Fukunaga, Alex S. Fukunaga, Blanca M. Fukunaga

Patent number: 7275542Abstract: A device for manipulating intrathoracic pressures comprises a compressible bag structure, and an interface member coupled to the bag structure. A one way forward valve is coupled to the bag structure to permit respiratory gas to flow to the patient when the bag structure is compressed. A one way exit valve is employed to allow respiratory gases to be pulled from the person's airway upon decompression of the bag structure to produce a negative intrathoracic pressure.Type: GrantFiled: May 11, 2005Date of Patent: October 2, 2007Assignee: Advanced Circulatory Systems, Inc.Inventors: Keith Lurie, Vern Menk, Todd Zielinski, James W.

Patent number: 7275545Abstract: Presbyopia is treated by a system using various lasers to remove a portion of the scleral tissue and increase the accommodation of the presbyopic patient's eye. Stable accommodation is achieved by the filling of the sub-conjunctiva tissue to the laser-ablated scleral areas. The proposed laser wavelength ranges from ultraviolet to infrared of (0.15-0.36) microns, (0.5-1.4) microns and (0.9-3.2) microns. Both scanning and fiber delivered systems are proposed to generate the ablation patterns. Laser ablation of the sclera may be conducted with or without opening the conjunctiva layer.Type: GrantFiled: December 2, 2004Date of Patent: October 2, 2007Assignee: Surgilight, Inc.Inventor: Jui Teng Lin

Patent number: 7275546Abstract: The symptoms of congenital heart failure are addressed in this surgical procedure for mounting a patch in the ventricle of the heart to reduce ventricular volume. Placement of the patch is facilitated by palpating a beating heart to identify akinetic, although normal appearing, tissue. An apical patch having an oval configuration facilitates return of the heart to a normal apical shape which enhances muscle fiber efficiency and a normal writhing pumping action. An inferior patch having a triangular configuration can also be used. The patches include a semi-rigid ring, and a circumferential rim to address bleeding. Patch placement is further enhanced by creating a Fontan-type neck and use of pledged sutures. Intraoperative vascularization and valve replacement is easily accommodated. Increased injection fraction, reduced muscle stress, improved myocardial protection, and ease of accurate patch placement are all achieved with this procedure.Type: GrantFiled: March 29, 2004Date of Patent: October 2, 2007Inventors: Gerald D. Buckberg, Constantine L. Athanasuleas

Method and system for determining the location of a medical probe using a reference transducer array
Patent number: 7275547Abstract: The present invention provides systems and methods for determining the coordinates of a location element mounted on a medical probe. First and second signals are transmitted between the location element and a first and second reference transducers, which may be arranged in a reference array that can be attached to a patient's skin. A transit time difference between the first and second signals is determined, e.g., using a thresholding or correlation technique. A distance difference between a first distance extending from the location element to the first reference element and a second distance extending from the location element to the second reference element is then determined based on the transit time difference. An angle between the reference array and the location element can then be determined based on the determined distance difference and a known distance between the first and second reference transducers.Type: GrantFiled: October 8, 2003Date of Patent: October 2, 2007Assignee: Boston Scientific Scimed, Inc.Inventor: Parker Willis -
Patent number: 7275548Abstract: Cigarettes manufactured using modified automated cigarette making apparatus can possess smokable rods having additive materials applied to paper wrapping materials as patterns. The additive materials can be applied to a continuous paper web using rollers.) One of those rollers can have a series of pockets in its roll face to receive additive formulation from a reservoir and to define the pattern of the formulation on the paper. The additive material in the recessed pockets of a first roller can be transferred in a controlled manner to a second roller and from the second roller to desired locations on the paper web. The additive material can also be applied to a transfer roller, transferred from the transfer roller to pick-up roller, transferred from the pick-up roller to an application roller, and transferred to the paper web that passes between the application roller and a back-up roller.Type: GrantFiled: August 22, 2003Date of Patent: October 2, 2007Assignee: R.J.
