The present invention relates to a SIM multiplexing device that provides a mechanism for multiplexing multiple SIM cards into a single SIM device. The SIM Mux device interfaces to the host device via the host device's standard SIM slot. The SIM Mux application resides on the SIM Mux logic device and communicates with the device over the SIM slot's SIM I/O line using standard ISO-7816 messages. The SIM Mux application allows a user to select the active SIM slot via a SIM application interface and directs the logic device which SIM socket to activate on the shared SIM I/O line, thus enabling the user to utilize any one of the populated SIM cards at one time.

A method for collecting volatile radioactive substances. The method includes irradiating a volatile radioactive substance on or under a contaminated material surface using microwave radiation and vaporizing the volatile radioactive substance, wherein the volatile radioactive substance comprises at least one of cesium and iodine. The method further includes recovering the vaporized volatile radioactive substance from the contaminated material. The method may be accomplished with and/or without physically collecting or isolating the contaminated material.

Methods for vaporization and remediation of radioactive contamination

Systems and methods for flaw detection and monitoring at elevated temperatures with wireless communication using surface embedded, monolithically integrated, thin-film, magnetically actuated sensors, and methods for fabricating the sensors. The sensor is a monolithically integrated, multi-layered (nano-composite), thin-film sensor structure that incorporates a thin-film, multi-layer magnetostrictive element, a thin-film electrically insulating or dielectric layer, and a thin-film activating layer such as a planar coil. The method for manufacturing the multi-layered, thin-film sensor structure as described above, utilizes a variety of factors that allow for optimization of sensor characteristics for application to specific structures and in specific environments. The system and method integrating the multi-layered, thin-film sensor structure as described above, further utilizes wireless connectivity to the sensor to allow the sensor to be mounted on moving components within the monitored assembly.

A method of estimating an arc-position of a distal transmitter is disclosed. In one embodiment, the method includes: (1) receiving radio frequency signals from said distal transmitter into an antenna having an array of feed horns and a Luneberg lens portion and (2) estimating an arc-position of said distal transmitter based on signal strengths provided by ones of said feed horns.

System and method for position or range estimation, tracking and selective interrogation and communication

An antenna mountable on a weapons platform, a communication system and methods of estimating position or range and conducting directional communication. In one embodiment, the antenna includes: (1) a Luneberg lens portion having a substantially planar surface and a convex surface, (2) a radio frequency (RF) reflective layer located proximate the substantially planar surface and (3) a feed horn array located proximate the convex surface and configured to receive RF signals through the Luneberg lens portion and reflected off the RF reflective layer.

A directional warning system and a method of warning of friendly forces. In one embodiment, the system includes: (1) a conductive shield having an opening at an end thereof and a radio frequency absorptive material located on an inner surface thereof, (2) a Luneberg lens located within the conductive shield and (3) a plurality of feed horns located proximate a portion of the Luneberg lens that is distal from the opening and arranged relative thereto based on a zone-of-interest with which the directional warning system may be associated.

System and method for interrogating and locating a transponder relative to a zone-of-interest

A method for determining the geolocation of an object such as a vehicle traversing the earth's surface or airborne thereabove includes employing a device which is capable of operating autonomously to transmit signals to a selected low earth orbit (LEO) satellite for relay to a receiving station whose position is known, identifying the device and its geolocation, speed, altitude and/or heading. The device includes a microcomputer which operates a Global Positioning System (GPS) receiver for receiving GPS signals to identify the device geolocation and the precise time. A nonvolatile memory on board the device stores LEO satellite ephemeris data, satellite operational and message formatting parameters, LEO satellite visibility footprint data and visibility contour information for the device caused by obstacles which are permanently or temporarily in proximity to the device during deployment and which block transmission of signals between the device and the LEO satellite, depending on relative positions. Geolocation information is transmitted to a LEO satellite for relay to the receiving station after calculation of covisibility of the satellite with the receiving station and the transmitter antenna for the device, taking into account the device visibility contour and heading. The device transmitter antenna may have a steering mechanism for causing the antenna to be aimed at a predetermined azimuth and elevation wherein the transmitted signals will be intercepted by the LEO satellite.

A system and method for transmitting information to a receiving station via one or more Low Earth Orbit (LEO) satellites includes a device which is capable of operating autonomously to transmit signals to a selected LEO satellite for relay to a receiving station identifying the device and its geolocation including longitude and latitude and/or speed, altitude and heading or course. The device includes a microprocessor which operates a Global Positioning System (GPS) receiver for receiving GPS signals to identify its geolocation and precise time. A nonvolatile memory onboard the device stores LEO satellite ephemeris data, and identification, operational and message formatting information to enable the device to transmit information including voice, data and/or the geolocation of the device to a selected LEO satellite, such as the next visible LEO satellite, for relay to a receiving station. The device may be operated to select the next visible LEO satellite for transmission of information when the satellite is visible and the device is within the LEO satellite visibility range or footprint. Alternatively, the device may select one or more LEO satellites for transmission at selected times and may store information, including geolocation data, when a selected LEO satellite is visible.
