Patent number: 8395298Abstract: 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.Type: GrantFiled: June 21, 2010Date of Patent: March 12, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Court E. Rossman

Publication number: 20130057698Abstract: A system and method for situational awareness and target cueing for use in military applications is disclosed. In extreme low light situations where the LLL sensor cannot provide SA information, the system allocates thermal information to the green SA channel to maintain the supply of contextual information to the user and thus situational awareness (SA) never drops below the native resolution of the thermal sensor. This improved SA capability, surpasses any existing LLL sensor technology in a single channel (stand-alone) application in overcast star light and below conditions.Type: ApplicationFiled: March 7, 2012Publication date: March 7, 2013Applicant: BAE Systems Information and Electronic Systems integration Inc.Inventors: Hilary L.

Patent number: 8387501Abstract: A method and apparatus for rapidly severing a decoy towline extending from an aircraft by a mechanical spring actuated cutting blade and a thermal fuse type of release mechanism eliminating a pyrotechnic actuation device. The cutting blade is biased toward cutting engagement with the towline by a preloaded coil compression spring retained in the loaded position by a length of a polymer cord. The polymer cord has a heater wire wrapped about a portion of the cord which is connected to a DC voltage supply. The heater wire melts the cords when electrically connected to the DC power supply which releases the restraint on the spring which then drives the cutting blade into severing engagement with the towline.Type: GrantFiled: April 10, 2009Date of Patent: March 5, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: James J.

Patent number: 8391271Abstract: Time synchronization among nodes in a wireless mobile ad hoc network (MANET) is obtained using a cross layer approach. Each node maintains a routing table that contains entries corresponding to other nodes of the network that are one or more hops away from the node, and topology messages are exchanged periodically among the nodes in order to update their routing tables. A network master node is selected, and remaining nodes that are one or more hops away from the master node are defined as slave nodes. The master node includes master timing information in the topology messages it transmits. The timing information is concatenated to include a first time (T1) at which a topology message was received by the master from each of the slave nodes, and a second time (td) at which the master node transmits a topology message after receiving all the topology messages from the slave nodes.Type: GrantFiled: March 19, 2010Date of Patent: March 5, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Shaomin Mo, John A.

Patent number: 8373518Abstract: Conductive segments (transmission line conductors) are positioned within a transmission line structure in order to generate multi-cycle microwave pulses. The conductor segments are switchably coupled to one or the other conductor of the transmission lines, inside the transmission line structure. Microwave pulses may be induced in the transmission line by closing the switches in a controlled manner to discharge successive segments, or successive groups of segments, into the transmission lines. The induced pulses travel uninterrupted along the transmission lines in a desired direction to the load. Efficiency of systems and energy delivered to the load in multi-section transmission lines is increased and/or maximized by adjusting the ratio of characteristic impedances associated with the transmission line conductor segments according to an optimum ratio.Type: GrantFiled: June 14, 2011Date of Patent: February 12, 2013Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: Simon Y.
