Abstract: A tree stand comprising a supporting base, a positioning sphere, and a compression collar. The supporting base is comprised of an annular cavity surrounding upwardly facing hemispherical socket. The annular cavity comprises an outer side wall including an upper threaded portion. The positioning sphere includes an outer spherical surface and a cavity for receiving a trunk of the tree.

When the positioning sphere is disposed in the hemispherical socket, and the compression collar is maximally threadably engaged with the supporting base, the flange of the compression collar is contacted with the outer spherical surface of the positioning sphere and immobilizes the sphere in the socket, thereby securing the tree in a desired upright position.

Abstract: A device uses cold plasma to treat cancerous tumors. The device has a gas supply tube with a delivery end. The gas supply tube is configured to carry a gas to the delivery end. A syringe is provided having an opening. The syringe is connected to the supply tube and configured to carry the gas to the opening. A first electrode is positioned inside said syringe, and a second electrode is positioned adjacent to the opening. The first and second electrodes excite the gas to enter a cold plasma state prior to being discharged from the opening of the syringe. An endoscopic tube can be used instead of the syringe. An exhaust tube can be provided to remove gas introduced into the body cavity by the cold plasma jet.

Abstract: A method for elevating a TRAIL-R1 expression in cancer cells to induce apoptosis. The method comprises the steps of receiving electrical energy having a specific voltage, frequency and power from an electrosurgical generator, up-converting the voltage and down-converting the frequency with a high voltage transformer having a primary coil and a secondary coil, the secondary coil having a larger number of turns than the primary coil, applying said converted electrical energy to an electrode in an electrosurgical hand piece, flowing an inert gas through said electrosurgical hand piece to produce a cold plasma at a distal end of said electrosurgical hand piece; and applying said cold plasma to cancer cells for 1 to 3 minutes. The inert gas may comprise, for example, helium or argon. In a preferred embodiment the cold plasma is applied to cancer cells for about 2 minutes.

Abstract: Certain example embodiments of this invention relate to techniques that harness air/wind power to charge and/or re-charge a battery of a vehicle that is at least partially electrically powered. In certain example embodiments, air/wind enters into a channel formed in a vehicle and turns a turbine which, in turn, generates electricity that may be used to charge and/or re-charge a battery of the vehicle. In certain example embodiments, the velocity of the air/wind may be increased within the channel by virtue of features including, for example, retractable and/or directional vanes and/or side wall elements that help create constricting locations (or choke points). In certain example embodiments, the velocity of the air/wind may be increased within the channel by virtue of features that produce the Coanda effect. Thus, for instance, both the Venturi effect and the Coanda effect may be used to increase the efficiency of the overall system.
