  • Patent number: 8450644
    Abstract: A system and method for providing multi-mode control of an ultrasonic welding system. In one embodiment, the control modes include the energy of the weld, the time of the welding process and the compression displacement of the parts being welded during the welding process. The method includes providing thresholds for each of the modes, and terminating the welding process after the threshold for each mode has been reached, the threshold for more than one mode has been reached or the threshold for one of the modes has been reached. The welding control can be either open-loop or closed-loop, where the open-loop process provides the mode thresholds and once one or more of those thresholds is reached the welding process is terminated. The closed-loop control provides feedback of the weld energy and/or the compression displacement so that the weld power and/or weld pressure can be increased or decreased accordingly.

  • Patent number: 7982180
    Abstract: A background component of reporter ion signals is determined by fitting a distribution function. A plurality of samples that include a protein labeled with a plurality of isobaric reporter ions is analyzed at a plurality of different times using a mass spectrometer, producing a plurality of mass spectra for the plurality of isobaric reporter ions. A cumulative distribution is calculated for an inverse coefficient of differential expression of the plurality of mass spectra using a processor. A Pearson Type IV distribution shifted by a constant value is fitted to the cumulative distribution and the constant value is solved for using the processor. A background component for each spectrum of the plurality of mass spectra is calculated from the constant value, a calculated coefficient of differential expression for each spectrum, and an average reporter ion signal value for each spectrum using the processor.

  • Publication number: 20110108181
    Abstract: A method for monitoring and controlling a vibration welding system includes collecting sensory data during formation of a welded joint using sensors positioned with respect to welding interfaces of a work piece. A host machine extracts a feature set from a welding signature collectively defined by the sensory data, compares and correlates the feature set with validated information in a library, and executes a control action(s) when the present feature set insufficiently matches the information. A welding system includes a sonotrode, sensors, and the host machine. The host machine is configured to execute the method noted above.

  • Patent number: 7919745
    Abstract: A corrected reporter ion intensity is calculated in tandem mass spectrometry based quantitation using isobaric labels. An analyte in each of two or more samples of a mixture of samples is labeled with a different isobaric label. The analyte is eluted from the mixture of samples and intensities of the eluting analyte are measured. An analyte intensity is selected at each of at least two times from the measured intensities. Tandem mass spectrometry is performed on the eluting analyte at each of the at least two times. A plurality of reporter ion intensities is produced. A system of linear equations is created expressing each reporter ion intensity of the plurality of reporter ion intensities as a sum of a background noise intensity and the product of a fragmentation efficiency and an analyte intensity. A corrected reporter ion intensity is calculated from a solution of the system of linear equations.

  • Patent number: 7807935
    Abstract: High frequency signals and power carried in a main cable delivering the same to a device are insured continuance flow within the main cable through use of a shorting bypass bar assembly in the device that is activated to electrically connect input and output ports of the device whenever the cover of the device is removed for servicing, for insuring continuity of the signal and power flow through the main cable. The shorting bypass bar itself is electrically connected to ground whenever the cover of the device is installed and the shorting bypass bar is disabled.
