Publication number: 20140081144Abstract: Systems and methods for processing echo signals in a Doppler ultrasound system from a region of interest. An ultrasound beam is electronically steered to deliver ultrasound to and receive echo signals from a plurality of sample locations in the region of interest. The echo signals for each sample location are processed to extract Doppler shift signals and Doppler shift data representing the Doppler shift signals are generated. The Doppler shift data accumulated for the sample locations can be used to detect the presence of blood flow in the region of interest, and identify the location in the region of interest at which the presence of blood flow is detected. The blood flow can be tracked by updating the location of the detected blood flow in the region of interest. The blood flow can be further monitored by combining the locating and tracking functionality with an m-mode ultrasound image.Type: ApplicationFiled: September 13, 2013Publication date: March 20, 2014Applicant: SPENTECH, INC.Inventors: Mark A.

Patent number: 7698075Abstract: A system and method for detecting damage to a structure is provided. The system includes a voltage source and at least one capacitor formed as a layer within the structure and responsive to the voltage source. The system also includes at least one sensor responsive to the capacitor to sense a voltage of the capacitor. A controller responsive to the sensor determines if damage to the structure has occurred based on the variance of the voltage of the capacitor from a known reference value. A method for sensing damage to a structure involves providing a plurality of capacitors and a controller, and coupling the capacitors to at least one surface of the structure. A voltage of the capacitors is sensed using the controller, and the controller calculates a change in the voltage of the capacitors. The method can include signaling a display system if a change in the voltage occurs.Type: GrantFiled: February 14, 2006Date of Patent: April 13, 2010Assignee: The Boeing CompanyInventors: Mark A Curry, Simon D Senibi, David L Banks

Patent number: 7133444Abstract: A DMT modem (40) is disclosed, in which a combined time domain equalizer and per-tone equalizer is applied to a received DMT signal. The combined equalizer includes a first FFT function (44) that is applied to a set of samples in a time-domain signal after the application of a time domain equalizer (42). The first FFT function (44) produces an initial FFT result, that is accumulated with a sliding FFT (46) performed upon difference values in the time domain samples. The sliding FFT results are applied to a per-ton equalizer (48) which applies a set of complex coefficients determined in training of the modem. A simple 1-tap FEQ (50) then can recover the signal. The combined equalizer enables per-tone equalization, in a manner that is compatible with conventional DSL training standards. According to a second embodiment, the per-tone equalization is performed only on selected tones of the multitone signal.Type: GrantFiled: August 28, 2002Date of Patent: November 7, 2006Assignee: Texas Instruments IncorporatedInventors: Xiaohui Li, Mark A.

Patent number: 6756935Abstract: A method, apparatus, and system for automatic detection of targets from radar data are disclosed. Ground moving target indicator radar is used to collect radar data which is then filtered to suppress intensity of the clutter ridge. For each working point in a set of radar data, a working first-sense circular transmit/first-sense circular receive radar cross section, a working first-sense circular transmit/second-sense circular receive radar cross section, and a working asymmetry angle are calculated from a scattering matrix, then analyzed to classify the working point as a target point or a clutter point. This analysis suitably is performed by comparing data calculated for each working point to basis data collected in a look-up table in which combinations of a first-sense circular transmit/first-sense circular receive radar cross section, a first-sense circular transmit/second-sense circular receive radar cross section, and an asymmetry angle have been classified as target points or clutter points.Type: GrantFiled: January 31, 2003Date of Patent: June 29, 2004Assignee: The Boeing CompanyInventors: William L.

Patent number: 5348015Abstract: This disclosure relates to a noninvasive means for detecting, counting and characterizing emboli moving through the arterial or venous circulation. An ultrasonic transducer is applied to the skin or other tissues of the subject at sites such as over the temporal bone on either side of the head of the subject, on the neck, on the chest, the abdomen, arm, leg, within the esophagus, or surgically exposed organs or blood vessels. Using standard ultrasonic Doppler techniques, Doppler-shifted signals are located which are proportional to the blood flow velocity in the blood vessel(s) of interest. Spectral analysis is performed on the received signal using the fast Fourier transform or other appropriate technique to determine the frequency components in the Doppler shift spectrum. Further analysis of the spectra is used to delineate and characterize Doppler shift signals due to blood from Doppler shift signals due to emboli having a variety of compositions.Type: GrantFiled: September 17, 1992Date of Patent: September 20, 1994Assignee: Applied Physiology and MedicineInventors: Mark A.
