Publication number: 20240144727Abstract: A wearable device has a plurality of sensors surrounding a user's arm or wrist and provides depth information about the user's environment. Each sensor in the plurality of sensors has a field-of-view that may include the user's arm, torso, and surrounding environment. A controller receives data from the plurality of sensors and merges the data to create a composite image or depth point cloud. The device utilizes low-resolution sensors, with the composite image having a greater resolution and field-of-view than any individual sensor. The device is worn on the user's arm or wrist and can be used for static or continuous hand pose estimation, whole-arm pose estimation, and object detection, among other applications.Type: ApplicationFiled: October 27, 2023Publication date: May 2, 2024Applicant: Carnegie Mellon UniversityInventors: Nathan Riopelle, Christopher Harrison

Patent number: 11946370Abstract: Asphaltene onset pressure of a formation fluid is determined by subjecting the fluid to a plurality of tests where depressurization is conducted at a different depressurization rate for each test while optically monitoring the fluid for asphaltene flocculation. The pressures at which asphaltene flocculation are detected in each test are fit to a curve as a function of depressurization rate, and the curve is extrapolated to a pressure (e.g., 0 psi) to provide the asphaltene onset pressure.Type: GrantFiled: March 13, 2023Date of Patent: April 2, 2024Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Matthew T.

Publication number: 20240092380Abstract: The disclosure relates to simplifying the integration of a peripheral with a vehicle. The complexity of modern vehicle electronics means that integration of a peripheral with a vehicle requires a reconfiguration of the vehicle electronics in order for the resultant upfitted vehicle to function as desired by the user. This restricts the set of users and enterprises which are able to successfully integrate a new peripheral with a vehicle. To make the task more approachable, a software application is described which presents a user with a graphical user interface enabling them to specify, at a high-level, rules of behavior for the upfitted vehicle. From the user's inputs via the graphical user interface, the application creates configuration data to be applied to the vehicle electronics in order to produce the desired behavior in the upfitted vehicle.Type: ApplicationFiled: September 19, 2022Publication date: March 21, 2024Inventors: Benjamin Moffatt, Ian Salsbury, Yasmin Jawad, Christopher Harrison, Jake Larsson, Bahareh Saboktakin Rizi, Joseph Hornby, Cheok Man Chu

Patent number: 11768191Abstract: Embodiments of the disclosure can include systems, methods, and devices for determining saturation pressure of an uncontaminated fluid. A technique facilitates fluid analysis in situ at a downhole location. Downhole saturation pressure measurements and downhole OBM filtrate contamination of a contaminated fluid may be obtained and a relationship may be determined between the saturation pressure measurements and OBM filtrate contamination. The relationship may be extrapolated to zero OBM filtrate contamination to determine the saturation pressure of the uncontaminated fluid. According to an embodiment, a sample of oil is obtained at the downhole location from oil in a reservoir. A downhole sampling system is used to determine whether a sample has contamination and other selected characteristics of the sample. The data obtained may be processed to provide a formation volume factor of the oil.Type: GrantFiled: May 13, 2021Date of Patent: September 26, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Younes Jalali, Ryota Tonoue, Hua Chen, Christopher Harrison, Kamal Kader, Youxiang Zuo, Adriaan Gisolf, Cosan Ayan, Michael Mallari Toribio, Chetankumar Natwarlal Desai, Oliver Clinton Mullins, Matthew T.

Patent number: 11763798Abstract: Embodiments are provided to recognize features and activities from an audio signal. In one embodiment, a model is generated from sound effect data, which is augmented and projected into an audio domain to form a training dataset efficiently. Sound effect data is data that has been artificially created or from enhanced sounds or sound processes to provide a more accurate baseline of sound data than traditional training data. The sound effect data is augmented to create multiple variants to broaden the sound effect data. The augmented sound effects are projected into various audio domains, such as indoor, outdoor, urban, based on mixing background sounds consistent with these audio domains. The model is installed on any computing device, such as a laptop, smartphone, or other device. Features and activities from an audio signal are then recognized by the computing device based on the model without the need for in-situ training.Type: GrantFiled: July 15, 2021Date of Patent: September 19, 2023Assignee: CARNEGIE MELLON UNIVERSITYInventors: Gierad Laput, Karan Ahuja, Mayank Goel, Christopher Harrison

Patent number: 11725511Abstract: Methods for obtaining in-situ, multi-temperature measurements of fluid properties, such as saturation pressure and asphaltene onset pressure include obtaining a sample of formation fluid using a downhole acquisition tool positioned in a wellbore in a geological formation. The downhole acquisition tool may be stationed at a first depth in the wellbore that has an ambient first temperature. While stationed at the first depth, the downhole acquisition tool may test a first fluid property of the sample to obtain a first measurement point at approximately the first temperature. The downhole acquisition tool may be moved to a subsequent station at a new depth with an ambient second temperature, and another measurement point obtained at approximately the second temperature. From the measurement points, a temperature-dependent relationship of the first fluid property of the first formation fluid may be determined.Type: GrantFiled: August 30, 2021Date of Patent: August 15, 2023Assignee: SCHLUMBERGER TECHNOLOGY CORPORATIONInventors: Hadrien Dumont, Christopher Harrison, Youxiang Zuo, Christopher Albert Babin, Li Chen, Vinay K.

Patent number: 11630569Abstract: Internet of Things (“IoT”) appliances are gaining consumer traction, from smart thermostats to smart speakers. These devices generally have limited user interfaces, most often small buttons and touchscreens, or rely on voice control. Further, these devices know little about their surroundings—unaware of objects, people and activities around them. Consequently, interactions with these “smart” devices can be cumbersome and limited. The present invention presents an approach that enriches IoT experiences with rich touch and object sensing, offering a complementary input channel and increased contextual awareness. The present invention incorporates a range sensing technology into the computing devices, providing an expansive ad hoc plane of sensing just above the surface with which a device is associated. Additionally, the present invention can recognize and track a wide array of objects, including finger touches and hand gestures.Type: GrantFiled: February 20, 2020Date of Patent: April 18, 2023Assignee: CARNEGIE MELLON UNIVERSITYInventors: Christopher Harrison, Gierad Laput

Patent number: 11589814Abstract: The disclosure describes a wearable, low-cost and low-power Electrical Impedance Tomography system for gesture recognition. The system measures cross-sectional bio-impedance using electrodes on wearers' skin. Using all-pairs measurements, the interior impedance distribution is recovered, which is then fed to a hand gesture classifier. This system also solves the problem of poor accuracy of gesture recognition often observed with other gesture recognition approaches.Type: GrantFiled: June 27, 2016Date of Patent: February 28, 2023Assignee: CARNEGIE MELLON UNIVERSITYInventors: Christopher Harrison, Yang Zhang
