Abstract: A method and system for installing warning spheres on utility power lines using existing commercial drones and an unique preassembled warning sphere with an inverted U shape opening in its lower half, one or more cable clamp in the upper part of the inverted U which matches the utility cable's diameter, number of strands and longitudinal spiral pitch. The warning sphere also has two receptacles in its circumference for catching the drones retractable landing gears fitted with matching bulges, enabling the safe lifting and flying of the sphere, The Drone also has a 3D stereoscopic camera which is integrated to its video system, thus enabling the precise navigating of the drone directly above the utility cable, and then directing the drone and sphere's U slot and cable clamp into the cable, either manually, or automatically through modulating of the sticks command of the remote control of the drone.

Abstract: A method and system for the rapid and cost effective deployment and operation of a geographically dispersed GNSS RF jammers array, with a deployed geometry of a Cartesian X,Y or Polar R/Theta grids, with a denser “first and/or second line” perimeter, for the purpose of jamming and defeating satellite based GNSS low flying guided munitions, including when equipped with CRPA anti jam antenna, by degrading their coordinates precision. The installed jammers grid creates a dense electronic “minefield” that the invading cruise missile must cross or penetrate within short distance to at least one jammer, close enough to make the first effective jamming and loss of tracking of the invader's GNSS receiver, after which the consecutive and neighboring jammers in the route to the defended target will be close and strong enough for the maintaining of GNSS signal loss, all the way to the target.

Abstract: A steam room for sanitizing people's external body parts and clothes, but also their breathing airways and respiratory tract, to reduce viral load and thereby mitigate the likelihood of spreading or contracting Viral contamination. Steam room has precise temperature and relative humidity control of a heater and mist generator, in which the mist water molecules contain an accurate concentration of a Chlorine or Ethanol based disinfectant, so that the water vapor or combined air/water mixture in the room that comes in contact with the sanitized person reaches but does not surpass the globally permitted concentration of free Chlorine for swimming pools, dressing rooms and spas. The room has thermally isolated quick doors allowing rapid entry and exit, and the signaling to guide the person when to enter, stay and breath, and exit, in the most suitable timing profile for the application.

Abstract: A system for Unmanned Air Vehicles and security applications that enables the use of a megapixels commercial digital camera with high resolution stills picturing capability, integrated with a camera control interface unit, long range wireless analog video link or CCTV link having 5 MHz bandwidth, but still able to transmit the high resolution pictures in full, by breaking the megapixels stored picture of the digital camera to a multitude of “subpictures”, each limited in resolution and 5 Mhz bandwidth. The wireless received analog video “subpictures” stream feed a P.C with frame grabber and software that reconstruct the complete megapixels picture.

Abstract: A direction finding system comprising: at least one first hand holdable unit comprising circuitry that transmits a radio beacon signal; and at least one second hand holdable unit having a display screen and comprising direction finding (DF) circuitry that receives a radio beacon (RB) signal transmitted by a first unit of the at least one first unit and determines from the received radio beacon signal an azimuth angle for the location of the first unit; wherein the controller generates a display on the display screen responsive to the azimuth angle that indicates a location of the first unit.

Abstract: A personal radiation-alerting device for use with a cellular telephone is provided. The radiation alerting device may comprise a radio frequency (RF) sampling unit adapted to measure the amplitude of the electromagnetic field generated by the cellular telephone over time, a computing unit adapted to compute the amplitude over time and to compare it with a predefined reference level and an alerting unit adapted to output an alert whenever the electromagnetic field exceeds the predefined reference level.

Abstract: A system for broadcasting a sporting event related to one or more moving objects (such as race cars) includes a plurality of stations disposed along the objects' trajectory. Each station includes an automated camera unit. A central command post receives the location of each object and sends commands to the respective cameras to cover the objects as they move. The signals from the cameras is then mixed automatically at the central control post and used to generate several video signals. The programs are transmitted directly to broadcasters, or are distributed via the Internet.
