Abstract: An apparatus and method for preventing entry of a ferromagnetic threat object into a no-entry zone of an MRI facility, by attaching a magnet to each threat object, and sensing movement of any such magnet within a pre-selected distance from the no-entry zone. An RFID tag and scanning antenna can be used to sense the presence of a threat object anywhere within the sensing range of the interrogation device, either separately or as an adjunct to the distance detection provided by the magnetic field source and sensor system.

Abstract: A method and an apparatus are disclosed, to screen patients or other areas for ferromagnetic objects, particularly for use intra-operatively in an operating room. The device comprises at least one magnetic field source, at least one magnetic gradiometer, and the associated electronics. The field source and the gradiometer are supported by an arm structure which can be manipulated to position the field source and the gradiometer at one or more positions near areas of interest, such as areas on a patient or other subject, and to orient the field source and the gradiometer so that the axis of the magnetic field is arranged along three different non-parallel, non-coplanar, axes to ensure detection of any ferromagnetic object regardless of its shape and orientation. The device can be manipulated to place the sensor arrays in close proximity to selected parts of a subject's body, for screening purposes.

Abstract: The cryopreservation media utilizes naturally occurring endogenous molecules and their chemical derivatives which act as osmotically active cryopreservative agents as well as molecules which insert into and protect specific regions of cellular membranes, lead to membrane repair, maintain normal cellular levels of energy metabolites, and act as antioxidants. Cryoperserved cells can be returned to a pre- cryopreservation state without damaging the cells resulting in a very high survival rate.

Abstract: A ferromagnetic detection pillar having one or more applied magnetic field sources and one or more magnetic field sensors, with the magnets and sensors arranged and adapted to detect a ferromagnetic threat object on one side of the pillar. A detection device, such as a motion detector or infrared detector, is also provided, to detect the presence of an object on a selected side of the pillar. A single free-standing pillar can be used, or two or more free-standing pillars can be arranged to constitute a variable aperture detection portal. Single sensors or multiple-sensor configurations can be used.

Abstract: A standardized, corrosion-resistant roof curb that can be shipped in a disassembled state, which an installer may assemble, size, locate and configure to provide an appropriate roof slope on any roof without welding, includes a panel and an extrusion configured to receive the panel, wherein the panel is trimmed according to the pitch of the roof. Methods of making and installing the roof curb also are disclosed.

Abstract: A screening portal for detecting the passage of ferromagnetic threat objects, whether permanently magnetized or not, by the use of AC induction coil sensors to detect a non-magnetized object, in combination with sensors capable of detecting the passage of a permanently magnetized object.

Abstract: Apparatus and method for boring a passage in a component having opposed ends and a longitudinal axis extending therebetween using a drill bit. A first motor turns the drill bit in a first direction about its axis of rotation, in which the axis of rotation is oriented substantially co-linear with the longitudinal axis of the component, and a second motor rotates the component about its longitudinal axis in a second direction, which is opposite to the first direction. The turning drill bit is moved longitudinally relative to the rotating component so that the relative movement therebetween causes the drill bit to bore the passage through a portion of the component substantially along its longitudinal axis.
