  • Patent number: 8317899
    Abstract: A shipboard system provides dry, oil-free utility air and inert gas for use on a marine vessel. A compressor converts ambient air into a pressurized air stream. The air stream is cooled by heat exchange with sea water in the vicinity of the vessel. The air stream is then dried in a dehydration membrane module, and some of the product of the dehydration module is taken for use as utility air. The remainder of the dried air is passed through an air separation module which includes a polymeric membrane. The product of the air separation module includes a nitrogen-enriched gas which is used as an inert gas on the vessel. The compressor is the only mechanically moving component of the system.

  • Patent number: 8237574
    Abstract: An above-water system provides automatic alerting for possible drowning victims in swimming pools or the like. One or more electro-optical sensors are placed above the pool surface. Sequences of images are digitized and analyzed electronically to determine whether there are humans within the image, and whether such humans are moving in a manner that would suggest drowning. Effects due to glint, refraction, and variations in light, are offset automatically by the system. If a potential drowning incident is detected, the system produces an alarm sound, and/or a warning display, so that an operator can determine whether action must be taken.

  • Patent number: 8177554
    Abstract: A pulp chamber locator assists a dentist in performing a root canal procedure. The device includes a generally circular plate and a plurality of struts extending from the plate. The plate has a hole in the vicinity of its center. The device is inserted over a tooth, such that the struts engage the cemento-enamel junction of the tooth. The hole then indicates the proper point of entry for a dental instrument. The device may also include a rotatable indicator for showing the proper angle of entry, to insure that the instrument reaches the pulp chamber of the tooth. The dentist adjusts the position of the indicator, based on information provided by an X-ray or equivalent, and positions the dental instrument so as to be generally parallel with the indicator.

  • Patent number: 8171710
    Abstract: An automatic lacer wraps bundles of polymeric fibers with thread, before the bundles are woven into a fabric mat and placed in a housing to form a gas-separation membrane module. A fiber bundle passes through a spool which is previously wound with thread on its outer surface. The thread is attached to the fiber bundle, so that when the bundle is moved through the spool, the thread is pulled from the spool, and automatically becomes wound around the bundle. Threads from two or more spools may be wrapped around the fiber bundle simultaneously. Lacing of the fiber bundles reduces the amount of tangling in the loom feeder, and improves the quality of modules made from the fiber bundles.

  • Patent number: 8146189
    Abstract: A patient alignment device includes a table and a rotatable member positioned to rotate relative to the table. The rotatable member may be a head-support plate or a board which supports substantially all of a patient's body. A motor moves the board or plate so as to align the patient's body, or a part of the body, in a desired direction. The board may be formed in two segments, the segments being selectively connectable to each other, the segments also being selectively connectable to the table by pins, at various possible pivot points. Positioning of the pins determines the mode of rotation of the board. The invention allows an operator to align the patient's body with precision, by remote control, and without interrupting the medical procedure.

  • Patent number: 8099972
    Abstract: A heating device includes a low-temperature heat store thermally coupled to a heat pump. The heat store is a buried pocket containing a permeable material and water. A high heat exchange capacity is thus achieved by exploiting both the high specific heat of the water and the high latent heat of liquefaction of the water contained in the heat store.

  • Patent number: 8056474
    Abstract: An electric circuit is applied to an object having a curved surface. The curved surface of the object is divided into sections, and the circuit is applied one section at a time. The circuit is formed between layers of dielectric material. The dielectric is applied by a computer-controlled device, which controls the position of a spray head and the rotation of the object, such that the spray head is held substantially perpendicular to the surface of the object at all times, and such that a controlled thickness of dielectric material can be deposited. The fine-featured circuits formed by the invention are rugged, and can be used on objects intended to be exposed to harsh environments.

  • Patent number: 8038814
    Abstract: A mat, to be placed beneath an appliance, has a base layer, preferably made of cardboard, a liquid-resistant layer, preferably of plastic, and a layer of batting. The layers are held together by a peripheral rim. The periphery of the mat includes straight and curved portions, such that when two similarly constructed mats are placed in abutment, the curved portions define areas not covered by the mats. Thus, the mats can be placed under an appliance, without disturbing the legs of the appliance, while still covering a majority of the area under the appliance. The mats provide containment for spills of liquid from the appliance, and also define barriers for deflecting food items which might otherwise become lodged beneath the appliance.

  • Patent number: 7941974
    Abstract: A flexible, inflatable shelter is held within a storage container. The shelter can be erected rapidly, by directing compressed gas held or produced within the container, into the flexible material which will define the finished shelter. Personnel using the shelter then enter through an air lock door located in the storage container. An air lock may be alternatively provided such that is located at least partly within the deployed shelter, and so that it does not occupy substantial space in the container. The container includes supplies necessary to sustain life for an extended period. The shelter can be used to protect personnel from harmful environments caused by accidents or explosions in mines, tunnels, industrial plants, and the like. The container is compact, but allows rapid deployment of the flexible material to produce a shelter which is of approximately the same volume, or greater, than that of the storage container.

  • Patent number: 7832122
    Abstract: A heel cup can be inserted into a shoe in order to define a posterior upward projection and lateral wings which surround the posterior and lateral faces of the calcaneum and which, through lateral notches, define a preferential deformation zone at, and in the direction of, the subtalar cone of the tibiotarsal joint. Moreover, a sufficiently-rigid connecting zone connects the posterior upward projection and the lateral wings, thus providing the shoe with good stability while enabling inversion and eversion foot movements. In this way, comfort is increased considerably, while the risk of articular injuries is reduced since the subtalar articulation is contained correctly upon reaching the limit thereof.
