Abstract: Implantable medical systems enter an exposure mode of operation, either manually via a down linked programming instruction or by automatic detection by the implantable system of exposure to a magnetic disturbance. A controller then determines the appropriate exposure mode by considering various pieces of information including the device type including whether the device has defibrillation capability, pre-exposure mode of therapy including which chambers have been paced, and pre-exposure cardiac activity that is either intrinsic or paced rates. Additional considerations may include determining whether a sensed rate during the exposure mode is physiologic or artificially produced by the magnetic disturbance. When the sensed rate is physiologic, then the controller uses the sensed rate to trigger pacing and otherwise uses asynchronous pacing at a fixed rate.

Abstract: A sterilization container having a lid and a bottom. The lid is provided with a plurality if bimetal valves that will fully open and fully close at a preset temperature. The lid also includes a pressure equalization valve to relieve pressure from the container that will occur during the heating and cooling process. The bottom and the lid are formed from light weight and highly durable material so provide an easily handled and long lasting apparatus. Each lid includes a plurality of recesses and each bottom includes a plurality of complimentary projections such that multiple containers can be safely stacked upon one another.

Abstract: A refrigerated freight vehicle includes a tractor truck with a cab interior, a trailer presenting a chamber, and a cooling system to refrigerate the chamber and cool the cab. The cooling system includes a powered compressor assembly, a trailer evaporator, and a truck evaporator, with the compressor assembly operable to circulate refrigerant through the evaporators.

Abstract: The frame for prone surgical positioning is a frame placed on a conventional operating table and used to position a patient in a prone position for surgery on the spine. The frame has an open, rectangular base defined by two longitudinal beams and two lateral beams, the size of the base being adjustable by sliding the beams though metal sleeves and clamping the beams in the desired relation by thumbscrews. The base supports six vertical posts, two of the posts being mounted on sleeves at one end of the longitudinal beams and between the longitudinal beams, the remaining four posts being mounted on the longitudinal beams. Resilient patient positioning pads are mounted on top of the vertical posts. The position of the vertical posts on the base may be adjusted, the vertical posts being mounted to the beams by metal sleeves clamped to the beams by thumbscrews.
