Abstract: A headgear mountable camera including a clip to mount the camera to a wearer/user, an image processing module, and wireless communications module. The wireless communications module can facilitate wireless data communications of video and audio to remote clients including smart hones and tablet computers, wherein the head mounted camera is mounted in at least one of: a sweatband, helmet, goggles, hat, and glasses. A camera that may be built into, mounted, and/or attachable/detachable as a camera lens to a variety of different headgear products and can transmit video data to computers, including portable handheld devices such as smartphones and tablets computers.

Abstract: An overexpanded thrust vector control nozzle has a converging extension section downstream of the jet exhaust stream deflecting section for defining a restriction or orifice. The orifice functions to elevate the exhaust pressure in the deflection section, which permits a reduction in nozzle size for operation at high and low altitudes. The orifice, which isolates the deflection section from outside ambient pressure, receives a deflected exhaust stream after it is turned in the direction opposite to that of the original stream deflection by the wall of the converging section. Control ports, which are adapted to communicate with a source of pressurized control fluid, are provided in the deflection section to position the exhaust stream.

Abstract: An exhaust nozzle has two frames each with flow attachment surfaces, mounted on its exit end in diametrically opposed relationship. Side plates are mounted on the sides of the attachment surfaces in such a manner that the plates project inwardly toward the axis of the nozzle. The attachment surfaces and their respective side plates define flow channels which receive only annular sectors of the exhaust stream emanating from the nozzle. Each flow channel is of sufficient radial depth and curvature to permit ambient pressure at a selected location on the attachment surface to detach the exhaust stream. A plurality of passages are provided in each frame for communicating ambient pressure to the respective attachment surfaces. A solenoid operated valve on each frame controls communication between the respective passages and the ambient atmosphere.
