  • Publication number: 20130093901
    Abstract: A method to increase the image formation speed in a digital ultrasound system including annular array of N elements with a plurality of transmit and receive channels. Selectively dropping one or more transmit or receive channels during image formation reduces the amount of data needed to form an image and thus increases the image formation frame rate. The improved frame rate does result in some reduction in resolution, SNR and potentially DOF, but image quality remains at an acceptable level.

  • Publication number: 20130347104
    Abstract: Analysis of executable binary code is performed without detection by defensive elements embedded within the executable binary code or within a system in which the executable binary code is executing. An identified suspect executable file is disassembled. Statically and dynamically analysis is performed on binary code of the disassembled executable file. An anti-anti-debugging function is implemented by executing program call functions in a manner which avoids detection of a debugging program by the defensive elements embedded within the executable binary code of the anti-debugging function of the executable binary code, thereby avoiding detection by the source of the suspect executable file.

  • Patent number: 4932414
    Abstract: A system is described for obtaining in real-time cross-sectional and 3-dimensional images of a body under study using ultrasonic energy. A piezoelectric transducer is positioned to emit ultrasonic energy and receive echo pulses. The transducer is electronically swept or physically rotated to produce a series of sectored scan planes which are separated by a known angular distance. The echo pulses are processed to produce an ultrasonic image in pseudo 3-dimensional display. By using data from one scan plane, processed as a B-scan image, cross-sectional data can be obtained. Such is combined in a display with an overlay to visually portray the object and positioning information or comparative data. The system is combined with a computer for data analysis and a therapeutic transducer for treatment.

  • Patent number: 5293871
    Abstract: An ultrasound system that enables determination of layer thicknesses and contours of a multi-layer organic body includes a transmitter/receiver for obtaining a radio frequency signal from echoes over a plurality of points on the organic surface. Each radio frequency signal is then deconvolved to remove apparatus generated noise and filtered to create an analytic signal that exhibits a magnitude related to an instantaneous rate of arrival of total echo energy received by the transmitter/receiver. Analytic signals from adjacent parallel scans are then cross-correlated and magnitude detected to determine energy peaks to enable accurate determination of echo producing surfaces of each layer of the multi-layer organic body across the plurality of interrogation points. In the application of the invention to Corneal Epithelium Mapping, a pupil monitoring system is included that disables the measurement system if the pupil's gaze wanders so as to cause a diversion of the optical axis.

  • Publication number: 20140151458
    Abstract: Fuel injectors of varying modes, shear or thickness, and megahertz are used to reduce the size of fuel droplets. The fuel injector has an expansion chamber and an orifice-containing face plate with a porous PZT material arranged adjacent to the face plate. The fuel passes through the porous PZT material as the PZT material is energized to realize reduced fuel particle size.

  • Patent number: 5623270
    Abstract: A phased array antenna system compensates for the effects of antenna flexure, vibration and movement, and thereby negates these effects by introducing an appropriate phase or time delay into the signals being radiated from and received by the discrete antenna elements comprising the phased array antenna. This compensation eliminates the need for massive rigid back structures to maintain antenna rigidity, which thereby simplifies antenna design.
