摘要： A system for visually tracking the trajectory of an in-flight golf ball through an x-y-z space above a driving range includes a plurality of cameras for respectively creating a video stream of the x-y-z space. Each video stream is presented on a dedicated camera focal plane with information on respective azimuth angles θ and elevation angles ϕ from the particular camera to the in-flight golf ball. A central computer is connected with the camera focal plane of each camera to identify a start point for the golf ball, to track its trajectory in the x-y-z space, and to filter out background clutter. A visual display is provided to show the in-flight golf ball from its start point to a target point in real time.

摘要： A gravity-based, non-invasive method of measuring a level of fluid in a container comprises use of at least one gravity meter located as proximate a center of mass of the fluid as possible. In a nuclear reactor system a method for monitoring the level of fluid in a nuclear reactor module, a report of a loss or gain of fluid within a cylindrical module may be generated from capturing a time series of gravity data from a first gravity meter mounted as an upper gravity meter and a second gravity meter mounted as a lower gravity meter, for example, proximate a cylindrical nuclear reactor module so as not to require any invasive conduit through, for example, a containment pressure vessel (CPV) or a reactor pressure vessel (RPV). In one embodiment, the upper and lower gravity meters are mounted on stable mounts as close to the fluid in the module as possible within a coolant pool or a structure containing cooled air. If a coolant pool of water surrounds a nuclear reactor module, the meters may be housed within a dry housing in the coolant pool such that the meters may be accessed from above the coolant pool and are located as close as possible to the reactor module and its contained mass of fluid.

摘要： An unmanned, lighter-than-air airship includes three omnidirectional thrust generating units. One unit is mounted at the fore-end of the airship to generate thrust in a plane that is perpendicular to the longitudinal axis of the airship. This unit controls pitch and yaw movements of the airship. The other two units are mounted on the airship equidistant from the first unit, and are located in a same midships plane that is perpendicular to the longitudinal axis. These two units generate thrust vectors that control roll movements of the airship and provide propulsion for the airship.

摘要： An apparatus for inflating and deploying an aerostat having a nose section and a tail section includes a cylindrical container for housing the deflated portion of the aerostat. The cylindrical container is formed with an open end and defines a longitudinal axis. A feed hose extends from a gas source, through the container to a hose end that projects axially from the open end of the container. The deflated aerostat is initially folded to juxtapose the nose and tail of the aerostat. Next, the nose of the aerostat is attached to the feed hose end and the remaining portion of the aerostat is folded and inserted into the container. As the tail section is inflated outside of the container, aerostat cloth is drawn from the container. A mechanism is provided to control the release of cloth from the container and maintain pressure in the inflating aerostat within a predetermined range.

摘要： A wireless system for locating a signal emitter includes at least three base stations for receiving the emitter signal, and a central processing site for converting information from the received signals into range estimates. Specifically, an antenna array at each base station for receives the emitter signal, and a beamformer isolates the direct path component of this received signal from interference and multi-path signals using cyclic phase minimizer techniques. In operation, an extractor is used to separate a cyclostationary feature from the direct path component of the emitter signal, and the cyclostationary feature is identified in an absolute time reference. The identified cyclostationary feature is then passed to the central processing site. At the central processing site, phase delay characteristics of the cyclostationary features from all participating base stations are compared with each other to obtain phase difference measurements. These phase difference measurements are then converted into differential range estimates for locating the emitter.

摘要： A hybrid radar receiver includes an antenna array for receiving an input signal having a radar signal from a signal emitter. Each array element outputs an analog signal on a respective data channel. For each data channel, an activatable A/D converter is provided. A dedicated hardware circuit, which typically includes a detector/log video amplifier that is coupled to a threshold/pulse digitizer, is included to determine when a radar pulse is being received. When the circuit determines that a pulse is being received, the circuit activates each A/D converter to generate a digital signal on each channel. When a pulse is not currently being received, the circuit deactivates each A/D converter and digital signals are not produced. Pulse parameter(s) generated by the hardware circuit and the digital signals on each channel are sent to a software equipped processor which implements a signal emitter identification algorithm.

摘要： A system and method for docking an airship to a mooring mast includes a thruster that is mounted to the fore end of the airship. When activated, the thruster generates a thrust vector that is substantially perpendicular to the longitudinal axis of the airship and is selectively directional. In particular, the configuration of the thruster can be changed to vary the direction of the thrust vector around the longitudinal axis to maneuver a connector on the thruster into contact with the mooring mast. Engagement of the connector to the mooring mast then docks the airship to the mooring mast.

摘要： Systems and methods for detecting targets using pulse-compressed radar signals are disclosed. In one application, relatively small targets that are masked by the time-sidelobes of a larger target's return signal can be detected. The methods include a signal expansion type algorithm that is used to process the pulse-compressed return signal. Specifically, a generalized Fourier expansion expression having a summation of PSF terms is used to expand the pulse-compressed signal. Each term represents a respective target and includes a point spread function and a complex coefficient. The signal expansion procedure can be used to determine a set of optimum complex coefficients, with one coefficient for each range bin. Doppler frequency can be used together with range to optimize the complex coefficients. Next, targets are detected by analyzing each range bin to determine whether the corresponding complex coefficient has an absolute magnitude greater than a pre-determined threshold.

摘要： A “wing in ground effect” aerial vehicle includes a wing mounted on a fuselage, and two cycloidal propulsion units for providing lift, thrust and longitudinal control. Additional lift is provided by a lighter-than-air gas such as helium contained in the fuselage. Operationally, the two cycloidal propulsion units and the volume of lighter-than-air gas are concertedly regulated to achieve “wing in ground effect” flight. Importantly, the two cycloidal propulsion units may operate in one of several modes, to include a curtate mode, a prolate mode, and a fixed-wing mode. Additionally, the vehicle may hover. Also, a thruster unit is mounted on the fuselage for providing forward thrust in combination with, or in lieu of, the two cycloidal propulsion units.

摘要： A wireless system and method for locating the position of a movable signal emitter located inside or adjacent to a structure includes establishing at least three base station sites at known locations around the structure. The signal emitter then transmits an omni-directional, low frequency, RF signal that is received at the base station sites. Phase information is measured at each base station site and communicated to a central processing site. At the central processing site, relative phase delays are used to geometrically calculate the position of the signal emitter.
