| 20110128003 | SYSTEM AND METHOD FOR MEASUREMENT INCORPORATING A CRYSTAL OSCILLATOR - A system, method and device for interrogating a downhole environment in a borehole beneath a surface includes a source of electromagnetic energy, operable to transmit an electromagnetic signal in the borehole, a sensor module, including a passive resonating circuit including a crystal oscillator having a resonant frequency that varies with changes in the condition in the downhole environment to reflect the electromagnetic signal and to modulate the electromagnetic signal in response to a condition in the downhole environment in the borehole and a detector positionable to receive the reflected modulated electromagnetic signal. | 06-02-2011 |
| 20110119281 | Methods for Discovering Analyst-Significant Portions of a Multi-Dimensional Database - Methods for discovering portions of a multi-dimensional database that are significant to an analyst can be computer-implemented. The methods can include specifying a data view having at least two dimensions and all records of the database. A plurality of operation iterations are then performed on the data view, wherein each iteration is a chain operation, a hop operation or an anti-hop operation. The operation iterations are ceased upon satisfaction of a termination criteria. The resulting data view can then be presented to an analyst. The methods can facilitate a users' knowledge discovery tasks and assist in finding relevant patterns, trends, and anomalies. | 05-19-2011 |
| 20090204009 | MEDICAL DEVICE SYSTEM AND RELATED METHODS FOR DIAGNOSING ABNORMAL MEDICAL CONDITIONS BASED ON IN-VIVO OPTICAL PROPERTIES OF TISSUE - A diagnostic system detects abnormal physical properties of tissue in a patient based upon optical properties of the tissue. A probe includes light delivery and capture fibers, and polarizers. Optical properties detected relate to polarized and unpolarized light into, and scattering from, the tissue. The optical properties detected are processed and analyzed to produce results indicative of the physical property(s) evaluated. System operation is controlled against pressure monitored via a pressure sensor coupled to the probe-tissue interface. The analysis corrects for patient physical characteristics as user inputs, such as menopausal or menstrual condition of women patients. Physical properties diagnosed include cervical dysplasia conditions in women patients, such as HSIL, cervical cancer, LSIL, or cervicitis. Analysis and diagnosis is based upon at least one of: ratios between scattered light signals captured from the tissue, slope of intensity over wavelength for scattered light signals captured, and hemoglobin-related parameters in the tissue. | 08-13-2009 |
| 20090108969 | APPARATUS AND METHOD FOR TRANSCRANIAL AND NERVE MAGNETIC STIMULATION - An electromagnet coil comprising Litz wire windings and power leads without break or interruption is cooled by a perfluorinated liquid by sensible and phase change heat transfer in a closed system. The electromagnet coil may be housed in a pentagonal or hexagonal pressure vessel to allow high packing densities in an array or helmet configuration. The helmet is then lowered over a human cranium for transcranial electromagnetic stimulation. The Litz wire windings reduce the power and voltages required for operation, yet allow production of over 2 T of accurately directed magnetic pulses for direct nerve or neuron stimulation. The perfluorinated liquid maintains the temperature of the helmet to less than 35-40° C., ensuring a comfortable temperature device for a human test subject. A utility cable connects the helmet to an external cooling unit and an external power supply. | 04-30-2009 |
| 20080229832 | AUTOMATIC TIME-OF-FLIGHT SELECTION FOR ULTRASOUND TOMOGRAPHY - Ultrasound sound-speed tomography requires accurate picks of time-of-flights (TOFs) of transmitted ultrasound signals, however, manual picking on large datasets is time-consuming. An improved automatic TOF picker is taught based on the Akaike Information Criterion (AIC) and multi-model inference (model averaging), based on the calculated AIC values, to improve the accuracy of TOF picks. The automatic TOF picker of the present invention can accurately pick TOFs in the presence of random noise with average absolute amplitude of up to 80% of the maximum absolute synthetic signal amplitude. The inventive method is applied to clinical ultrasound breast data, and compared with manual picks and amplitude threshold picking. Test results indicate that the inventive TOF picker is much less sensitive to data signal-to-noise ratios (SNRs), and performs more consistently for different datasets in relation to manual picking. The technique provides noticeably improved image reconstruction accuracy. | 09-25-2008 |
