Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
