Abstract: A piezoelectric power apparatus wherein piezoelectric material forms one wall of a liquid-filled container. Water pressure within the container is made to rapidly vary either by a cam operated piston or a motor operated ball valve acting on a pressurized liquid flow. The piston reciprocates through a wall of the container to alternately increase and decrease the pressure in the liquid. The ball valve periodically interrupts the pressurized liquid flow to alternately increase and decrease the pressure in the liquid. In either case, the alternate increase and decrease in the pressure in the liquid creates pressure variations in the piezoelectric material.

Abstract: A means of reducing fluid density in front of Savonius blades by installing magnus rotors to accelerate onrushing fluid away from the blade itself. Several magnus rotors are mounted on either external side of the centerline of each blade, so as the Savonius rotor is revolved by the surrounding fluid and the magnus rotors are revolved on either side of the centerline in opposite directions, then fluid pressure is reduced and the Savonius rotor's speed is increased. Also, if the magnus rotor is formed from a sheathed flexible shaft and attached to an underlying contoured surface of a vehicle, such as a racing car or a helical Savonius rotor, fluid resistance to the forward motion of the vehicle is reduced.

Abstract: Disclosed is an interoperability gateway system that provides backup connection between a dispatch center and a Land Mobile Radio (LMR) system in the event the dispatch center is disconnected from the LMR system. In general, this may be accomplished by providing an RF link between the disconnected site and the interoperability gateway via a controller, or interoperability site network interface (ISNI), that is activated when the dispatch center is disconnected from the LMR system. The interoperability gateway provides the backup connection by allocating a control station for each channel available at the disconnected LMR system. When compared to conventional dispatch console backup schemes, the disclosed interoperability gateway system greatly reduces the equipment needed to provide dispatch console backup, thereby decreasing equipment and operation costs, and simplifying operation by providing a solution that is virtually transparent to the dispatcher.

Abstract: A piezoelectric power apparatus wherein waterproofed piezoelectric material is located within a water-filled container. Water pressure within the container is made to rapidly vary either by a cam operated piston rotated by a water turbine or a motor operated ball valve. A flowing water current is made to operate the ball valve which interrupts periodically the water flow, or the continuous water flow is made to operate the piston through the agency of a water turbine-operated cam.

Abstract: There is provided a method for designating a delivery batch of content to be delivered that includes the steps of: (1) performing a step of selecting a content silo and (2) performing a step of choosing a source type with respect to the selected content silo, The method can also include performing a step of indicating a respective tag that is associated with the respective source type that has been chosen with respect to the selected content silo.

Abstract: Water tends to expand in volume when heated up and contract in volume when heat is taken out of it. This invention relates to systems where solar energy causes pressure changes in water occupying fully a rigid closed container. Pressure energy is allowed to escape the container in a controlled way to operate a reaction turbine and shafted D.C. generator to produce electrical energy.

Abstract: A biologically implantable containment device having a wet seal, the device being adaptable for drug formulations or cell suspensions. A porous membrane, in a tubular configuration, is formed and can be configured as part of a closed cell-tight system for loading. During loading, the containment device membrane is wet, while the loading system remains cell-tight. The containment device is wet-sealed through a combination of heat and pressure, while the system remains cell-tight. Sealing the containment device substantially or completely eliminates metabolic functioning of any organisms in the vicinity of the closure. The wet-seal is formed by melting a thermoplastic material that is in contact with the membrane. The containment device is separated from the cell-tight loading system, which remains closed after separation.
