| 20090251537 | OBJECT CONTENT NAVIGATION - A surveillance system for monitoring a selected object that comprises a multiplicity of video cameras, a software application and at least one computerized medium. The computerized medium enables operating the application and the application is operatively associated with the cameras, which are installed in different locations in a surveillance area. The system allows a user to select at least one object such as an image or an area that is filmed by at least one of said cameras and monitor said object by automatically operating cameras that are associated with the object's coordinates' location, where the associated camera enables filming the selected object. | 10-08-2009 |

| 20090056305 | SCALABLE FLAT-PANEL NANO-PARTICLE MEMS/NEMS THRUSTER - A scalable flat-panel nano-particle MEMS/NEMS thruster includes a grid having a plurality of electrodes to establish electrical fields. A liquid is disposed in a liquid reservoir of the grid. The liquid is positioned within the electrical fields. A plurality of nano-particles are suspended in the liquid. A plurality of MEMS and NEMS micron-size vias are disposed in the grid. The electrical fields extract the plurality of nano-particles from the liquid and accelerate the nano-particles in the vias to provide propulsion system thrust. | 03-05-2009 |

| 20110258981 | MICRO-CATHODE THRUSTER AND A METHOD OF INCREASING THRUST OUTPUT FOR A MICRO-CATHODE THRUSTER - A magnetically enhanced micro-cathode thruster assembly for providing long-lasting thrust is provided. The micro-cathode thruster assembly includes a tubular housing, a tubular cathode, an insulator, an anode and a magnetic field. The tubular housing includes an open distal end. The tubular cathode is housed within the housing and includes a distal end positioned proximate the open distal end of the housing. The insulator is in contact with the cathode forming an external cathode-insulator interface. The anode is housed within the housing, proximate the open distal end of the housing. The magnetic field is positioned at or about the external cathode-insulator interface and has magnetic field lines with an incidence angle of about 0 to about 90 degrees and preferably about 4 to about 30 degrees relative to the external cathode-insulator interface. | 10-27-2011 |

| 20100177891 | Digital video protection for authenticity verification - A method and apparatus for verifying the authenticity and integrity of an ordered sequence of digital video frames, without having access to the original recording, by embedding therein a respective series of digital signatures based on a secret key, or keys, and on the video content of respective frames. Signatures are camouflaged by embedding in transform coefficients of a transformed representation of the video data in parts of the frame corresponding to motion. If there is sufficient motion to contain all of the signature bits, a supplementary technique embeds in high-texture areas of a frame. A final fall-back is to embed in a pre-defined default zone. A method of predicting when supplementary embedding is needed enables the process to be applied in a single pass allowing real-time operation. Verification is done during decoding by comparing, for identity, embedded signatures with signatures calculated anew using the method employed to embed. | 07-15-2010 |
