Patent number: 11568991Abstract: A diagnostic tool includes a sensor for capturing at least one biosignal produced by a patient's heart and a computer device that implements a neural network iteratively trained via machine learning to generate a prediction about a heart condition of the patient. After the neural network is trained, the computer device can convert the at least one biosignal to a multi-dimensional input matrix for the deep neural network generated from a number (N) of biosignals captured by the sensor. The computer device then processes the multi-dimensional input matrix through the deep neural network, which subsequently outputs the prediction about the heart condition of the patient.Type: GrantFiled: July 22, 2021Date of Patent: January 31, 2023Assignee: HEART INPUT OUTPUT, INC.Inventors: Utkars Jain, Adam A.

Patent number: 7623411Abstract: A connection system for connecting external devices to a streamer. The connection system comprises three outer collars maintained collinearly aligned by a stabilizing member, such as a lightweight, rigid tube, attached to each outer collar. The tube extends parallel to the bores of the outer collars. The forward and aft outer collars ride on races formed on the periphery of inner collars clamped around mounting structure in the interior of the streamer. An external device is attached to the forward collar and to the intermediate collar, which does not ride on an inner collar. The spacing between the forward and intermediate collars is fixed by the standard spacing of the two attachment points in standard external devices. The spacing between the forward and aft collars is set by the specified spacing of mounting structures in the interior of the streamer.Type: GrantFiled: May 25, 2007Date of Patent: November 24, 2009Assignee: Input/Output, Inc.Inventors: Eddie J.

Publication number: 20080181717Abstract: A connection system for connecting external devices to specified locations on a marine seismic streamer. Inner collars are clamped to the cable at specified locations along its length. Each inner collar forms a circular race encircling the cable. An outer collar attached to an external device rotatably receives the inner collar and the encircled streamer in its bore to allow the streamer to rotate freely within the outer collar relative to the external device. The outer collar has an inner face bounding and defining the shape of the bore. The inner face is tapered from an intermediate position outward toward front and rear edges of the outer collar to form a bore that is wider at the front and rear edges than at the intermediate position. This flaring out of the bore provides the streamer three degrees of angular freedom to position itself within the bore.Type: ApplicationFiled: January 31, 2007Publication date: July 31, 2008Applicant: INPUT/OUTPUT, INC.Inventors: Andre' W.

Publication number: 20070286021Abstract: A seismic spread has a plurality of seismic stations positioned over a terrain of interest and a controller programmed to automate the data acquisition activity. In one aspect, the present disclosure provides a method for forming a seismic spread by developing a preliminary map of suggested locations for seismic devices and later forming a final map having in-field determined location data for the seismic devices. Each suggested location is represented by a virtual flag used to navigate to each suggested location. A seismic device is placed at each suggested location and the precise location of the each placed seismic devices is determined by a navigation device. The determined locations are used to form a second map based on the determined location of the one or more of the placed seismic devices. Using the virtual flag eliminates having to survey the terrain and place physical markers and later remove those physical markers.Type: ApplicationFiled: June 8, 2007Publication date: December 13, 2007Applicant: INPUT/OUTPUT, INC.Inventors: Scott Hoenmans, Martin Williams

Publication number: 20070286022Abstract: A seismic spread has a plurality of seismic stations positioned over a terrain of interest and a controller programmed to automate the data acquisition activity. In one embodiment, the controller forms a queue of sources that are ready to fire and initiating the firing of the sources according to a preset protocol. The sensor stations each include power management circuitry that may shift or adjust the power level of the sensor station during the data acquisition activity. During operation, the controller broadcasts data that the power management circuitry of each sensor station uses to determine the appropriate energy state for that sensor station. This determination may be made using the broadcast data alone or in conjunction with other data such as a GPS-determined position of the sensor station. Thus, in one aspect, each sensor station self-selects an energy state according to the broadcast status of the data acquisition activity.Type: ApplicationFiled: June 8, 2007Publication date: December 13, 2007Applicant: Input/Output, Inc.Inventors: Andrew Bull, Dennis Pavel, Scott Hoenmans, Keith Elder, Donald Clayton, Igor Samoylov, Richard Eperjesi
