Antenna Array for passively modulating radio frequency signals. Specifically, an antenna array or system comprising a plurality of retroreflective antennas configured to passively receive a radiofrequency (RF) signal from a source, and configured to reflect the RF signal; and a passive modulation circuit, electrically connected to the plurality of retroreflective antennas, configured to modulate the RF signal to represent a code, wherein the code comprises information, and further comprising: a plurality of RF switches. Additionally, a method for passively reflecting modulated signals, comprising generating a radiofrequency (RF) signal at a source; receiving the a RF signal with a plurality of retroreflective antennas; passively modulating the signal's amplitude to create a modulated RF signal, wherein the modulated RF signal comprises a code, and wherein the code further comprises a unique identifier associated with the plurality of retroreflective antennas; and passively reflecting a modulated signal back to the source.

Antenna array for passively modulating radio frequency signals

A system and method may include energizing one or more of a plurality of electromagnets contained within and fixedly distributed about a first region of a structure and de-energizing other of the electromagnets to attract a substance contained and movable within a second region of the structure to the energized electromagnets and change the center of gravity of the structure. The structure may be disposed on a surface or within a liquid, where energizing and de-energizing of the electromagnets causes the structure to move about the surface or within the liquid in a desired fashion. The substance may be a magnetic or magnetizable substance. Energizing and de-energizing the electromagnets may be performed by a controller responsive to a signal received from a sensor or transceiver.

System and method for electromagnetic-based propulsion

A system for controlling a plurality of vehicles can include at least one communications bus and a plurality of RFID detection tags that can be fixed to the communications bus equidistant from each other to define a plurality of RFID regions. Each vehicle within an RFID region can further include an RFID reader for receiving information from, and transmitting information to, the RFID tags. As the vehicle enters the RFID region for a particular RFID tag, the position of the vehicle (within the RFID region) can be communicated to the communications bus. A traffic control unit can be connected to the communications bus, and monitor can be in communication with a plurality of remotely controlled traffic control assets, such as stop signs, yield signs, traffic cones. After receiving position information on the vehicle, the monitor can selectively activate the traffic devices remotely to control vehicle traffic flow.

Remotely controlled vehicle control system

A data transfer device comprising: a body; a tip coupled to the body, wherein the tip has a dielectric constant value suitable for interacting with a capacitive touch screen of a separate device; a control unit mounted to the body; and an electronic switch mounted to the body and operatively coupled to the control unit, wherein the switch is disposed to connect the tip to a ground source when the switch is in a closed configuration and to break the connection between the tip and the ground source when the switch is in an open configuration.

In one preferred embodiment, an aircraft marshaling wand controller displays aircraft marshaling instructions to a pilot on a video display monitor on-board an aircraft, such as an aircraft on an aircraft carrier. When an aircraft marshal uses arm motion gestures to form aircraft marshaling instructions for the pilot on the aircraft, the wand controller of the present invention senses or detects those gesture motions, and generates digitized command signals representative of those gesture motions made by the aircraft marshal. A wireless transceiver then transmits those digitized command signals to the aircraft for display on the video monitor for viewing by the pilot.

Wand controller for aircraft marshaling

A system includes a controller, a Hall-effect sensor and transceiver connected to the controller; and a flux-producing element having a plurality of magnetic flux lines emanating therefrom. The system may be secured to or contained within a wearable glove. The flux-producing element may be coupled to an object separate from the wearable glove. The Hall-effect sensor transmits a Hall-effect sensor signal to the controller when the Hall-effect sensor is perpendicular to at least some of the plurality of magnetic flux lines. The Hall-effect sensor signal may include data received from the flux-producing element. The controller transmits a controller signal to the transceiver after receiving the Hall-effect sensor signal. The controller signal may include input from a motion sensor and/or an orientation sensor connected to the controller. The transceiver may transmit the signal to a remote processor. The signal may be used for gesture recognition, information coding, and/or information processing.

The system may be secured to or contained within a wearable glove. The RFID sensor is configured to transmit an RFID sensor signal to the RFID sensor reader when the RFID sensor is within the detection region. The RFID sensor reader is configured to transmit an RFID sensor reader signal to the controller after receiving the RFID sensor signal. The controller is configured to transmit a signal to the transceiver after receiving the RFID sensor reader signal. The signal may include input from a motion sensor and/or an orientation sensor connected to the controller. The transceiver may transmit the signal to a remote processor via an antenna. The signal may be used for gesture recognition, information coding, and/or information processing.

A Hall-effect system for providing inputs into a processor includes at least one magnet for establishing a magnetic field, a remote sensor unit and a receive station. The magnet is sized and adapted to be worn on a user's finger, while the remote sensor unit is adapted to be worn on a user's thumb. The remote sensor unit includes a Hall-effect sensor that senses changes in the magnetic field due to the motion of the magnet relative to the Hall-effect sensor. The Hall-effect sensor detects the magnetic field changes, and the remote sensor unit generates a sensor output corresponding to the magnetic field changes. The receive station is connected to the processor. The receive station receives the output from the remote sensor unit and converts the sensor output into an input for the processor.
