| 20100125192 | FOCUSED ULTRASOUND SYSTEM - A focused ultrasound system includes an ultrasound transducer configured to emit focused ultrasound energy toward a subject and a positioning system configured to position the ultrasound transducer to localize the focused ultrasound energy within a target location. The positioning system includes a drive apparatus to translate the ultrasound transducer along at least one axis of motion and a motor controller to control the drive apparatus. The focused ultrasound system also includes a control system connected to the motor controller that is programmed to receive imaging/location data from an imaging system, determine positional coordinates of the target location based on the imaging/location data, and register the positional coordinates of the target location with the positioning system. The positional coordinates are sent to the motor controller via an input signal to cause the motor controller to control the drive apparatus so as to translate the ultrasound transducer. | 05-20-2010 |

| 20080269646 | System and Method for Detecting Swallowing Activity - A system and method for detecting swallowing activity is provided. In an embodiment, a method includes receiving an electronic signal from an acceleronic signal from an accelerometer that represents swallowing activity, extracting at least two features from the signal, classifying the signal as a type of swallowing activity based on the extracted features, and generating an output of the classification. Exemplary activities include swallows, aspirations, movement and vocal artifacts. By indicating whether an activity is a swallow or an aspiration, the manner in which a patient afflicted with an increased likelihood for aspirations is fed can be adjusted to increase the likelihood of achieving a swallow instead of an aspiration during feeding. In turn this could reduce hospitalizations for aspiration pneumonia in patients with acute or chronic injury. | 10-30-2008 |

| 20090147991 | METHOD, SYSTEM, AND COMPUTER PROGRAM FOR DETECTING AND CHARACTERIZING MOTION - A method for motion detection/characterization is provided including the steps of (a) capturing a series of time lapsed images of the target, wherein the target moves between at least two of such images; (b) generating a motion distribution in relation to the target across the series of images; and (c) identifying motion of the target based on analysis of the motion distribution. In a further aspect of motion detection/characterization in accordance with the invention, motion is detected/characterized based on calculation of a color distribution for a series of images. A system and computer program for presenting an augmented environment based on the motion detection/characterization is also provided. An interface means based on the motion detection/characterization is also provided. | 06-11-2009 |
| 20100160833 | METHOD AND SYSTEM OF SEGMENTATION AND TIME DURATION ANALYSIS OF DUAL-AXIS SWALLOWING ACCELEROMETRY SIGNALS - The proposed invention is a method and system for the segmentation of dual-axis accelerometry signals for the purposed of identifying problematic swallowing events. The method and system employ a sensor, a data collection means including an algorithm for the analysis of the data. The proposed invention considers the stochastic properties of swallowing signals in both directions, A-P and S-I to extract events associated with swallowing. A segmentation algorithm may be applied to the signals to establish the time duration of swallows and swallows may be classified with respect to gender, body mass index, age or types of swallow. | 06-24-2010 |
