20080278388 | Broadband Blade Antenna Assembly - A lightweight broadband blade antenna assembly is incorporated into the surface of an airfoil, such as a structure component of an aircraft, or a separate airfoil (blade antenna) attached thereto. A first metallized area is formed on the airfoil adjacent a leading edge of the airfoil. A second metallized area is formed on trailing edge of the airfoil and is spaced from the first metallized area by a first gap which is configured to provide a capacitive coupling between the first and second metallized areas. A third metallized area is formed on the cap portion of the airfoil and is spaced from the first metallized area by a second gap and is electrically connected in series with the first and second metallized areas. RLC circuits are electrically connected across tuning gaps formed in the third metallized area to provide a broadband response. | 11-13-2008 |
20090128289 | Methods for coupling an RFID chip to an antenna - A method for mounting multiple small RFID chips onto larger antenna. The chips are mechanically aligned with an interdigitated gap at the feed point of the antenna by electrostatic or magnetic techniques. In an alternate embodiment RF field coupling between the chips and the antenna is employed. | 05-21-2009 |

20120175999 | RADIOISOTOPE FUELED ROTARY ACTUATOR FOR MICRO AND NANO VEHICLES - The invention provides an actuator apparatus and method where a source provides electrons to a target material wherein electrical work is performed. A beta emission process comprises a source material emitting electrons which are then captured by a target material. The actuator's source vanes rotate within an electric field between the target chutes' walls, generating torque. The principal providing torque and power is the change in energy as a vane gets closer to the outer walls. During the release and capture process, electrical work is performed which, in turn, is transferred into mechanical work in the form of rotation of the rotor. Specific applications include a radioisotope fueled rotary actuator for micro and nano air vehicles employed as the main form of propulsion. | 07-12-2012 |
