Abstract: A method and apparatus to control movement of a vehicle using a plurality of thrust-producing devices formed in at least one control surface is disclosed. A supply of power to the plurality of thrust-producing devices that are configured to propel gas through the control surface to produce thrust is controlled such that a physical displacement of the control surface is generated. The physical displacement is in accordance with the supply of power to the plurality of thrust-producing devices and controls the movement of the vehicle.

Abstract: Apparatus and methods for generating a partial vacuum in a cavity are disclosed. In one method, a suction unit is disposed on a surface and includes a plurality of embedded suction generation devices that suction gas therethrough. The suction generating devices are powered-on to form a cavity defined by at least the surface and the suction unit and gas is evacuated from the cavity to generate the partial vacuum.

Abstract: A control system for controlling the operation of a plurality of micro thrusters arranged in a plurality of parallel horizontal rows and a plurality of parallel vertical columns, the control system requires a power source, a first plurality of power lines connected to the power source and coupled to at least one micro thruster of the plurality of micro thrusters in a horizontal row of the plurality of parallel horizontal rows, a second plurality of power lines connected to the power source and coupled to at least one micro thruster of the plurality of micro thrusters in a vertical column of the plurality of parallel vertical columns, and a control unit coupled to the power source to control activation of the first plurality of power lines and activation of the second plurality of power lines.

Abstract: Conveying systems and methods are provided that selectively controls gas-propelling devices to move objects over the conveyer table at different speeds and in different directions. The systems and methods include a conveyer table having of an array of gas-propelling devices that propel gas from a surface of the table. Each of the of gas-propelling devices can have layers arranged in a stack and a through-hole in the stack and the table. The surfaces of each of the layers are exposed in the interior of the through hole and a heating/cooling device selectively heats and/or cools the layers to generate thrust.

Abstract: A heating and cooling system for a building utilizes lower vents which open into lower portions of rooms of a building, and upper vents which open into upper portions of rooms of the building. When the system is operating in a heating mode, heated air is delivered into the upper portions of the rooms through the upper vents and air is removed from the rooms through the lower vents. When the system is operating in a cooling mode, cool air is delivered into the rooms through the lower vents, and air is removed from the rooms through the upper vents. Operating the heating and cooling modes in this fashion provides the most efficient operation of the heating and cooling system.

Abstract: For a playing experience in a computer game that more accurately captures the experience of professional football or another sport, it would be advantageous to be able to hide from an opponent a selected player formation and play selection until the play actually begins. Similarly, in other computer games such as war games and role-playing games, it is desirable to be able to hide from other players certain properties—e.g., equipment, disposition of forces, etc.—held by each player while making this information available to the player holding these properties. In the present invention, a signal processor is inserted in the link between the game console and the television set and auxiliary displays are provided that are visible only to individual players. The signal processor detects certain frames containing information that should not be displayed to all players, removes that information from the signal to the television set and displays it instead on the appropriate auxiliary display.

Abstract: A stand-alone renewable-energy generating device which generates electric energy from renewable energy sources, such as the sun or wind, in a stand-alone context. To allow users to asses their contribution to carbon dioxide emission savings, a sensor element that is configured to generate emission savings data representative of electric energy units generated by using a renewable energy device. Further, a clock device is configured to generate a time data representative of at least one of a time and a date specification and unique sensor-ID data are stored in a memory. A processor unit is configured to time-stamp the emission savings data by combining it with the time data. The processor unit retrieves the sensor-ID data to combine them with the emission savings data to form savings profile data. A communication interface is configured to communicate the savings profile data directly or indirectly via a network system.

Abstract: A solid-state device that is capable of imparting a directional momentum via thermoelectric microelements. High surface area is used to enhance the efficiency of heat transfer. The device can be operated in adiabatic mode in order to minimize thermal emissions.

Abstract: A method and device for creating a temperature gradient among a plurality of temperature gradient devices. Each device is formed of a first layer of conductive material having a top surface and a bottom surface. The first layer is adjacent to a second layer of conductive material and has electrical resistive heating properties. A power supply is used to provide a current flow through at least the first layer when the power supply is activated. When activated, the resulting current flow causes the second layer to heat and thus create a temperature gradient between the bottom surface of the second layer and the top surface of the first layer. Activation of the power supply is controlled by a control unit so that activation of adjacent temperature gradient devices is avoided for a predetermined time after activation of the first temperature gradient device.
