Publication number: 20230346306Abstract: Embodiments include methods and systems for automated eating detection. Systems comprise a continuous glucose monitor (CGM), accelerometer, and processing unit. During a first time period, the processing unit receives glucose readings and a first set of acceleration readings. The processing unit identifies an eating episode if the glucose readings satisfy one or more criteria. Using the identified eating episode and first set of acceleration readings, the processing unit generates an individual model that identifies eating episodes using acceleration readings without using glucose readings. During a second time period, a processing unit uses the individual model and a second set of acceleration readings to identify a second eating episode. Some embodiments may use additional sensor types (for example, PPG or heart rate) to identify eating episodes in the first or second time period, generate the individual model, or any combination thereof.Type: ApplicationFiled: July 7, 2023Publication date: November 2, 2023Inventors: Steven Catani, Jed Ludlow, Tyler Stigen, Joseph A. Roxas, Nino Paul D. Batanay

Patent number: 8479345Abstract: A system and method for retrieving a pipeline tool from a pipeline includes a speed control drive section that includes a primary bypass flow valve and a failsafe valve located in a central bypass flow passageway of the drive section. The failsafe valve is placed under the control of a controller. The controller is programmed to release the failsafe valve under prescribed failure conditions. An actuating means moves the failsafe valve between a normally opened positioned and a closed position in response to the controller.Type: GrantFiled: August 12, 2009Date of Patent: July 9, 2013Assignee: TDW Delaware, Inc.Inventors: Jed Ludlow, Keith Glass, Jonathan Warkentin, Paul Laursen

Patent number: 8319494Abstract: A pipeline inspection tool includes two pole magnets oriented at an oblique angle relative to the central longitudinal axis of the tool body. An array of sensor coil sets is located between opposing edges of the two pole magnets and oriented perpendicular to the central longitudinal axis. Each sensor coil set includes a transmitter coil and two opposing pairs of receiver coils that are gated to receive reflections from the wall of a tubular member. Because the line of sensor coils is rotated relative to the magnetic bias field, the receiver coils are in-line with, and have the same angular orientation as, the transmitter coil. The tool provides improved sensitivity to small defects, substantial decrease in RF pulser power requirements, full circumferential coverage, self-calibration of the transmitted signals, and less interference between transmitter coils caused by acoustic ring around.Type: GrantFiled: December 18, 2009Date of Patent: November 27, 2012Assignee: TDW Delaware Inc.Inventors: James Simek, Jed Ludlow, John H.
