The continuous speech recognition engine may utilize Hidden Markov Models to create real time continuous speech recognition and feedback.Type: ApplicationFiled: September 27, 2007Publication date: February 28, 2008Inventors: Kenneth Glynn, Jerome Mahoney

Publication number: 20080048831Abstract: A method to use an RFId (Radio Frequency Identification)-identifier for recognition of roll ware, such as a roll of paper or like, whereby an RFId-identifier is being exploited that is to be placed essentially in connection with a core and which includes a transponder, being formed at least of a RFId-microcircuit and an antenna. For recognition of roll ware, a RFId-identifier is being used that is to be placed in connection with the core and that exploits a magnetic field, existing essentially uniformly all over the same in a radial direction. Also provided is an arrangement applying the method.Type: ApplicationFiled: June 2, 2005Publication date: February 28, 2008Applicant: Top Tunniste OYInventor: Pauli Tossavainen

Publication number: 20080048832Abstract: A radio frequency identification device includes an integrated circuit including a receiver, a transmitter, and a microprocessor. The receiver and transmitter together define an active transponder. The integrated circuit is preferably a monolithic single die integrated circuit including the receiver, the transmitter, and the microprocessor. Because the device includes an active transponder, instead of a transponder which relies on magnetic coupling for power, the device has a much greater range.Type: ApplicationFiled: August 30, 2007Publication date: February 28, 2008Inventors: James O'Toole, John Tuttle, Mark Tuttle, Tyler Lowrey, Kevin Devereaux, George Pax, Brian Higgins, David Ovard, Shu-Sun Yu, Robert Rotzoll

Publication number: 20080048833Abstract: Methods and circuits for using measurement based threshold(s) to detect Radio Frequency IDentification (RID) tag responses in readers are described. Tag response itself is detected based on a measurement that is compared to a measurement during a tag silent period. Beginning and/or end of tag response are also detected using multiple measurements during tag response. The initial detection threshold may be replaced with a lower second threshold once demodulation of the tag response begins.Type: ApplicationFiled: January 11, 2007Publication date: February 28, 2008Inventor: Ronald Oliver

Publication number: 20080048834Abstract: A system is disclosed for minimizing coupling nulls between an electromagnetic field derived from one or more sources and a plurality of randomly oriented RFID tags, wherein the electromagnetic field is rotated relative to the tags such that no tag is persistently located in a coupling null relative to the field. The source of the electromagnetic field may include a passive antenna or loop that changes its orientation relative to a direction of movement of the tags. The source of the electromagnetic field may further include an active antenna or loop that is electromagnetically coupled to the passive antenna or loop. A method for minimizing coupling nulls between the electromagnetic field and the randomly oriented tags is also disclosed.Type: ApplicationFiled: July 30, 2007Publication date: February 28, 2008Applicant: Tagsys SASInventor: Yves Lenevez

Publication number: 20080048836Abstract: An implantable medical device having a transceiver for transmitting/receiving wirelessly transmitted data, which is turned off or switched into an energy-saving rest state between individual data transmissions via the transceiver and having a waking unit which is implemented to switch the transceiver by a waking signal from its turned-off state or its rest state into its fully operational state, the waking unit having a low-power receiver and a waking control unit of which the low-power receiver is implemented to monitor multiple predefined frequency ranges in such a way that in case of a transmission of sufficient signal strength in one of the frequency ranges, it generates an output signal and outputs it to the waking control unit and of which the waking control unit is implemented to analyze output signals of the low-power receiver and output a waking signal to the transceiver which switches it on or to fully operational.Type: ApplicationFiled: June 27, 2007Publication date: February 28, 2008Inventors: Joern BUNGARTZ, Joachim Reinke

Publication number: 20080048840Abstract: The delayed start-up verbal warning unit includes an audible alarm that comprises a verbal warning and instructions. The unit is connected to a control circuit for machinery, e.g., an oil well pumping unit. The control circuit includes a means of generating a start-up signal for the machinery. Where the machinery is an oil well pumping unit, the unit operates to issue a verbal warning and instructions related to imminent start-up of the pumping unit. Playback of the verbal warning delays propagation of the start-up signal to the pump, thereby providing people in the area the opportunity to avoid injury by evacuating the area. Additionally, start-up signal status may be sent by the unit to a Supervisory Control And Data Acquisition (SCADA) system for further processing and analysis.Type: ApplicationFiled: August 21, 2007Publication date: February 28, 2008Inventors: Donnie L.
