  • Patent number: 9646172
    Abstract: Systems and methods are disclosed for securely storing and accessing data records. In an embodiment, a random seed value and a time period counter received from a warrant server. The seed value may correspond to a starting time period and be updated by applying a one-way function to the seed value upon expiration of the starting time period and each subsequent time period. A data record may then be received including one or more data fields. A data field may be identified to use as an index value, and an encryption key may be generated based on the current random seed value and the index value. The data record and/or the index value may then be encrypted using the encryption key, and the encryption key may be securely deleted after encrypting the data record and/or the index value. The warrant server may then assist with recovery of the data.

  • Patent number: 8114359
    Abstract: An SNCR distribution grid for introducing a NOx reducing reactant into a flue gas flow. The grid is made of one or more elements which are formed by fluid-cooled tubes to which membrane pieces are attached, preferably by welding, to form conduits in between the tubes. The fluid-cooled tubes may be cooled by water and/or steam and the distribution grid is disposed in the flue gas flow. To admit the reactant into the flue gas, nozzles are provided in the membrane and the reactant is conveyed from a location external of the furnace or combustor enclosure, into the conduits so formed, and thence out into the Flue gas flow via the nozzles.

  • Patent number: 7529349
    Abstract: A portable, automated telephone line test device includes a test module which applies test signals to a telephone line to be tested and detects electrical characteristics of the telephone line, and a user interface module. The user interface module includes a microprocessor, a display, a keyboard and a program memory in accordance with a standard microcomputer architecture. The processor of the user interface module is programmed to control the test module to perform a pre-programmed sequence of tests. The display provides indications of the tests being performed. The programmed sequence is varied by the device according to test results. Depending on the results obtained, the device also provides interpretative diagnostic messages and instructs the user to carry out additional test procedures.

  • Patent number: 6357658
    Abstract: A multifunctional scanner having a first processor, an image scanner, a laser scanner, and a host interface port is provided. The image scanner scans documents to detect the presence of images imprinted thereon, generates image data based on the detected images, generates mark-sense row/column data based on downloaded data masks, and forwards the image data to the first processor. The laser scanner scans documents to detect the presence of bar-code symbols imprinted thereon, decodes the bar code symbols, generates bar code information based on the decoded bar code symbols, and forwards the bar code information to the first processor. The host interface port electrically couples the first processor to an external host processor. The first processor receives the image data from the image scanner, converts the image data into a host datastream, and forwards the host datastream to the external host processor via the host interface port.
