Abstract: A control system and method for tensioning an active tether for a multirotor unmanned aerial system is provided. The control system includes a tensioning pulley and a tensioning spring. The tensioning spring is arranged to generate a variable tension force on the active tether. A transducer is connected adjacent to the tensioning spring to sense a linear displacement position of the tensioning pulley and to transmit a position signal to a controller. The position signal is proportional to the linear displacement position. A servomotor in communication with the controller receives a control signal from the controller in response to the position signal. The servomotor drives a cable reel. The cable reel is rotatably mounted in the frame for spooling the tether in response to rotation of the servomotor. The cable reel is rotated by the servomotor to maintain a predetermined tension on the tensioning spring.

Abstract: An electrical receptacle assembly for use in a modular wall system, the electrical receptacle assembly including an electrical receptacle receiving assembly, at least one electrical receptacle electrically coupled to the electrical receptacle receiving assembly and first and second plates. The first plate is coupled to the electrical receptacle receiving assembly. The first plate has an opening through which the at least one electrical receptacle is accessible. The second plate is installed substantially parallel to the first plate. The second plate having an opening that only accommodates access to the at least one electrical receptacle.

Abstract: A system and method for consolidating used nuclear fuel rods using tools operably suspendable in a recess containing the used nuclear fuel rods. The systems and methods safely consolidate the used nuclear fuel rods in containers.

Abstract: A desktop receptacle includes: a housing having a top surface with a receptacle opening formed therein; an electrical receptacle including at least one electrical port and pivotally mounted within the housing adjacent to the receptacle opening, the electrical receptacle having a recessed position where the at least one electrical port is below the top surface of the housing and an exposed position where the at least one electrical port is at least partially exposed above the top surface; and a gas spring connected to the electrical receptacle so as to bias the electrical receptacle toward the exposed position.

Abstract: A non-spinning projectile that is self-guided to a laser designated target and is configured to be fired from a small caliber smooth bore gun barrel has an optical sensor mounted in the nose of the projectile, a counterbalancing mass portion near the fore end of the projectile and a hollow tapered body mounted aft of the counterbalancing mass. Stabilizing strakes are mounted to and extend outward from the tapered body with control fins located at the aft end of the strakes. Guidance and control electronics and electromagnetic actuators for operating the control fins are located within the tapered body section. Output from the optical sensor is processed by the guidance and control electronics to produce command signals for the electromagnetic actuators. A guidance control algorithm incorporating non-proportional, “bang-bang” control is used to steer the projectile to the target.
