20130026263 | EXTRACTING MINED ORE, MINERALS OR OTHER MATERIALS USING SENSOR-BASED SORTING - A method of analyzing minerals received within a mining shovel bucket includes collecting data associated with ore received in the bucket, where the bucket includes at least one active sensor, where the ore includes one or more mineral, and where the ore is within a field of the active sensor. The method further includes determining a content of the minerals using the data, transmitting information relating to the content of the minerals to a decision support system, and sorting or processing the ore based on an output of the decision support system. Collecting data associated with the ores may include generating source signals, applying the source signals to the active sensor, collecting a response from the active sensor, and comparing the response with a reference or threshold. Other features are disclosed. | 01-31-2013 |

20120104554 | FLEXIBLE AND ON WAFER HYBRID PLASMA-SEMICONDUCTOR TRANSISTORS - Preferred embodiment flexible and on wafer hybrid plasma semiconductor devices have at least one active solid state semiconductor region; and a plasma generated in proximity to the active solid state semiconductor region(s). Doped solid state semiconductor regions are in a thin flexible solid state substrate, and a flexible non conducting material defining a microcavity adjacent the semiconductor regions. The flexible non conducting material is bonded to the thin flexible solid state substrate, and at least one electrode is arranged with respect to said flexible substrate to generate a plasma in said microcavity, where the plasma will influence or perform a semiconducting function in cooperation with said solid state semiconductor regions. A preferred on-wafer device is formed on a single side of a silicon on insulator wafer and defines the collector (plasma cavity), emitter and base regions on a common side, which provides a simplified and easy to manufacture structure. A preferred embodiment array of flexible hybrid plasma transistors of the invention is an n+pn PBJT fabricated between two flexible sheets. One or both of the flexible sheets is transparent. The overall array structure is planar, and the planarized structure is sealed between the two flexible sheets. Visible or ultraviolet light is emitted during operation by plasma collectors in the array. In preferred embodiments, individual PBJTs in the array serve as sub-pixels of a full-color display. | 05-03-2012 |

20140339677 | HYBRID PLASMA-SEMICONDUCTOR TRANSISTORS, LOGIC DEVICES AND ARRAYS - A hybrid plasma semiconductor device has a thin and flexible semiconductor base layer. An emitter region is diffused into the base layer forming a pn-junction. An insulator layer is upon one side the base layer and emitter region. Base and emitter electrodes are isolated from each other by the insulator layer and electrically contact the base layer and emitter region through the insulator layer. A thin and flexible collector layer is upon an opposite side of the base layer. A microcavity is formed in the collector layer and is aligned with the emitter region. Collector electrodes are arranged to sustain a microplasma within the microcavity with application of voltage to the collector electrodes. A depth of the emitter region and a thickness of the base layer are set to define a predetermined thin portion of the base layer as a base region between the emitter region and the microcavity. Microplasma generated in the microcavity serves as a collector. Logic devices are provided in multiple sub collector and sub emitter microplasma devices formed in thin and flexible or not flexible semiconductor materials. | 11-20-2014 |
