  • Patent number: 8176762
    Abstract: A device and method for prediction and/or control of the profile and/or shape of rolled metal strip. The device and method are compatible with both cluster-type and non cluster-type mills. The device and method employ a customized deflection model of the rolling mill, thereby combining the advantages of well-known finite element method with other relevant methods to allow real-time operation of the rolling mill without the computational complexities of such methods. In one form, the customized deflection model helps to obtain a compact, linear, and flexible analytical model with non-iterative solution, multiple continuous elastic foundations, third-order displacement fields, simple stress-field determination, and capability to compute dynamic deflection characteristics.

  • Patent number: 7988055
    Abstract: Passive radio frequency identification tags comprising a simple antenna and a circuit with a unique frequency-dependent response, in place of an RF-powered integrated circuit with control logic, is disclosed. The unique frequency-dependence of the circuit, which may simply be a feature of the antenna, conveys the tags identification. Multiple frequency-dependent circuit RFID tags can be simultaneously identified and located in 3-D space through use of antenna arrays and sampling at multiple frequencies in order to provide spatial resolution.

  • Publication number: 20110081073
    Abstract: In one embodiment, a method for generating an ensemble classifier may include transforming multidimensional training data into a plurality of response planes. Each of the response planes includes a set of confidence scores. The response planes are transformed into a plurality of binary response planes. Each of the binary response planes include a set of binary scores corresponding to one of the confidence scores. Combinations of the binary response planes are transformed into sets of diversity metrics according to a diversity measure. A metric is selected from the sets of diversity metrics. A predicted performance of a child combination of the recognition algorithms corresponding to the combinations is generated. The predicted performance is based at least in part upon the metrics. Parent recognition algorithms are selected from the recognition algorithms based at least in part upon the predicted performance. The ensemble classifier is generated and includes the parent recognition algorithms.

  • Publication number: 20100241009
    Abstract: A system is disclosed for wirelessly detecting movement of a target. The system comprises a reference oscillator, a transmitter, a receiver, a demodulator, and a processor, wherein: the reference oscillator generates references frequencies for the transmitter, the receiver, and the demodulator; the transmitter generates a continuous-wave signal at a frequency based on the transmitter reference frequency and wirelessly transmits it to the target; the receiver wirelessly receives a reflected signal from the target having a phase angle corresponding to movement of the target and converts the reflected signal into an intermediate frequency signal based on the receiver reference frequency; the demodulator demodulates the intermediate frequency signal into an in-phase component and a quadrature component; and the processor converts the in-phase component and the quadrature component into a movement signal corresponding to movement of the target.

  • Patent number: 7332296
    Abstract: The invention provides methods for quantifying enzymatic activity of an enzyme with a known substrate. The methods employ SELDI-TOF mass spectrometry, and are suitable, in particular, for assaying aspects of the renin-angiotensin system. The methods may be utilized to assess and/or monitor biological conditions associated with the renin-angiotensin system prior to the manifestation of known physiological and biomarkers for such conditions. The methods are suitable for analysis of pharmacological effectors of the renin-angiotensin system, and are particularly suitable for automation and high-throughput screening assay design.

  • Patent number: 7034730
    Abstract: A pipelined delta-sigma modulator (PDSM) analog to digital converter (ADC) architecture is disclosed where each stage of the pipelined ADC includes a delta sigma modulator with a digital low pass filter and a corresponding analog low pass filter that precisely matches the digital low pass filter. An error signal is generated at each stage based on the difference of the low pass filtered analog input and the low pass filtered digital output of the delta sigma modulator (after converting to an analog signal). The digital outputs of each stage are passed through the appropriate low pass filter stages so all digital signals have been subjected to the same filtering prior to combining in a digital error correction circuit. The present invention also uses a compensation filter to correct any errors in the pass band caused by the low pass filtering and to help reject unwanted noise outside the pass band.

  • Patent number: 6893986
    Abstract: Methods are provided for adjusting and controlling the stress between layers of material in a multilayer structure. A first stress is configured in a region of stress on the substrate material. A second material is then deposited over the substrate. A second stress results between the substrate and the second material such that a net stress results where the net stress is a function of said first and second stresses. As such, the first stress can be configured to achieve a predetermined, desired net stress. For example, the first stress can be configured to cancel out the second stress such that the net stress is substantially zero.

  • Patent number: 6883376
    Abstract: A method for the determining ultrasonic sound propagation speed and wall thickness of a tubular object. Time-domain and frequency-domain analyses are used, where the latter can determine acoustic dispersion if the specimen is made up of a dispersive material. Data is sensed from a series of transmitted ultrasonic waves, some of which are reflected. The data can be used to calculate speed of sound in the tube, as well as wall thickness. Inherent in the data is the speed of the ultrasonic wave; accordingly, correction for temperature variations in the tube is not required. The calculations based on measured speed of sound quantities produces more accurate results than in calculations where the speed of sound in the specimen is assumed.
