Abstract: This invention relates generally to pet and child toys and drones. More specifically, the invention relates to an apparatus and method of operation for an autonomous or remotely controlled fetch toy drone for pets and children that is safe to operate and retrieve, extends the fetching range beyond that of a throw-type fetch toy, and also provides numerous other features, such as actuated shut-down and audio broadcast features, as well as video and audio recording capabilities, and supplemental stimuli features.

Abstract: The invention provides a system for providing passage of fluid lines through an RF shield, the device comprising an RF shield having external and internal surfaces; a channel defined by the RF shield and extending from the external surface to the internal surface of the RF shield; a hollow cylinder rotatably communicating with said channel and extending substantially the length of the channel; a longitudinally extending region of said cylinder defining a gap adapted to receive a fluid conduit; mounting plates attached to the external surface and the internal surfaces of the RF shield; a movable member having a handle, the movable member attached to either end of the channel, the handle in slidable communication with the mounting plate so as to slide about the periphery of the plate; and a depending end of the handle rigidly attached to the cylinder which in turn is in rotatable communication with the circular plate such that the handle can be manipulated to a first position to allow loading of the conduit int

Abstract: A modular system to attenuate radio frequency encroachment and acoustic noise into an enclosure is described. The system uses a door leaf, a jamb for the leaf, and acoustic and RF seals removably positioned on the jamb, or on the door, or both. The jamb can include radio frequency, radiation, and acoustic attenuation seals.

Abstract: A radio frequency shield which reversibly transects an electromagnetic frequency enclosure is provided. The shield includes first a number of panels attached to a first surface of the enclosure. The panels are adapted to move through a first arc relative to the first surface. Shield also includes a first panel from the number of panels having a first leading edge capable of transecting the first arc. The shield further includes a second number of panels attached to a second surface of the enclosure. The second set of panels is adapted to move through an arc relative to the second surface of the enclosure. Also a second panel from said second set of panels has a second leading edge capable of transecting the second arc so as to oppose the first leading edge. Finally, the shield includes a means for reversibly attaching the first leading edge to the second leading edge while simultaneously establishing electrical communication between the first and second plurality of panels.
