Abstract: A CRTR (Continuous Resonant Trap Refractor) is the name given to waveguides having a tapered core and a cladding which disperses radiant energy admitted via the aperture at the wide end of the tapered core, and emits the energy in sorted fashion via the cladding. As individual waves reach a width of the core in which they can not propagate along the tapered core waveguide, and are emitted via the cladding sorted at frequency dependent depth. Alternatively, the CRTR admits radiant energy via the cladding and mixes and emits the combined energy via the aperture. The present invention is directed The invention discloses several uses of CRTRs and aspects of the invention include inter alia imagers, camouflage devices, radar and heat signature reduction devices, communications, target designation, and the like.

Abstract: A layered waveguide stack radiant energy converter array having a plurality of superposed waveguides, each waveguide having a core layer having a radiant energy converter disposed therein, and two cladding layers disposed on opposing sides of the core. In some embodiments the conductive layers are electrically coupled to the converter and act as charge carriers for it, and in other wires are provided for individual converters. Each waveguide has at least one inlet for passage of radiant energy therethrough, the inlet extending between the cladding layers, such that radiant energy entering the waveguide impinges on at least two layers of the waveguide, the inlet further defining a minimum cutoff frequency for the energy to propagate in the waveguide. In some embodiments such as solar panels, energy is harvested. In other embodiments energy is detected such as for example is done in a camera focal plane sensor. In some embodiments the stack is used to emit light.

Abstract: A pixel structure, displays, and display panels comprising a plurality of pixel structures, are provided. The pixel structure comprising: a Continuous Resonant Trap Refractor waveguide having a tapered core with an aperture for emitting the light and a narrower end or tip, the tapered core having cladding disposed thereabout, the core and the cladding both being transmissive of light; and a plurality of light sources disposed for coupling light into the core via the cladding. Preferably the light sources are disposed within layers of substrate, which may form lateral waveguides. An optional plurality of light sources disposed at an angle offers emitting a simultaneous plurality of images, each having a different polarization, for 3D viewing, and other desired emissions at varying polarizations.

Abstract: A pixel structure having a cladding and tapered core waveguide, the core dimensioned to refract EM radiation through the cladding at differing depth dependent on the wavelength of the radiation, and a plurality of detectors disposed to convert the band of radiation they receive into electrical signals. In some embodiments the detectors are disposed within lateral waveguides, and in some embodiments below the tapered core waveguide. Further disclosed is an image array sensor comprising a plurality of such pixel structures. Further disclosed is an array comprising stacked layered waveguides having detectors disposed therewithin, and a plurality of refractors to refract different bands of EM radiation into differing waveguides.

Abstract: A method, apparatus, and system are provided to facilitate protecting media such as images, documents, video streams, and the like, from unauthorized copying or distribution. The method is based on requiring certain conditions to be filled prior to, and during, display of the media on a user display. The conditions for display may require pointing device cursor placement, operating certain keys, and the like. Permissions are granted to users by the media owners and the permissions are checked prior to display. Thus the user is prevented from copying the media and using it illicitly, and the media owner may share media while at the same time maintaining control over the use thereof. The system may also be utilized to provide time-limited access to certain materials.

Abstract: A controllable port redirector comprising a stack module insertable within a communication protocol stack, preferably between the data-link and the network layer. The redirector uses a rule base, at least partially downloaded from a control host, to decide on redirection of selected packets. The invention further provides a method for communication using at least partial remotely supplied rule base. Thus communications from the computer may be remotely and transparently controlled. Optionally the invention further provide a method for providing secured communication utilizing port hopping technique, controlled by a rule set which forms a hoping order, and utilizing different rules of packets from the same transmission stream, thus increasing the difficulty in monitoring the stream as a whole. Other services that may be established by the invention include replacing certain servers like DNS servers, providing a walled garden communication environment, and the like.

Abstract: An automatic documentation generation and management system and method, for documenting configurable systems such as complex software applications and hardware systems is disclosed. The method retrieves configuration parameters from the configurable system and utilizes them to automatically generate an explanatory document specific to the configured system. The invention also discloses a documentation appliance system, which is a dedicated documentation server coupled to the configurable system via a communication network, preferably via an Intranet. In yet another alternative, the invention may be practiced by integrating code for automatic documentation generation within the configurable system program.

Abstract: A device to warn a ship crew of submerged objects in their immediate vicinity, combined with alarm and logging facilities. The device is composed of one or more sonic or ultra sonic transducers placed aboard the ship, with coverage arranged so as to give surrounding "envelope" to the sides and to the area ahead of the vessel, as well as some predetermined downward looking angle. The transducer or transducers are connected to an electronic distance measuring device that will measure distance to possible obstacles, similar to conventional sonar techniques. The measurements in each direction are compared by an electronic processor against a table of minimum distances, and if the distance falls below the predetermined value for a given direction, an alarm is activated. In addition, all alarms, cancellations of alarms, activation and deactivation of the system are logged automatically with an identification of the operator.
