Abstract: A method of distributing oil to a component within a gas turbine engine includes directing a first oil flow from an oil source to an engine component and back to the oil source, directing a second oil flow from the oil source to a generator driven by the engine and back to the oil source, monitoring a parameter of the second oil flow downstream of the generator and upstream of the oil source, detecting a contaminant in the second oil flow based on the parameter, and reducing the second oil flow to the generator when the contaminant is detected without reducing the first oil flow to the engine component. A shared oil system for a component of a gas turbine engine and a generator driven by the gas turbine engine is also discussed.

Abstract: Apparatus is disclosed for monitoring, measuring and/or estimating a force applied to a body or body part of a vertebral mammal. The apparatus includes an acceleration sensor for measuring acceleration of the body or body part relative to an inertial frame of reference and for providing data indicative of the acceleration. The acceleration sensor includes at least one inertial sensor, a memory device adapted for storing the data, and a processor adapted for processing the data to evaluate a reaction force that correlates to the data. The processor may be configured to execute an algorithm for evaluating the reaction force, based on one or more correlation components such as mass, speed and/or velocity associated with the body or body part. A method of monitoring and/or estimating a force applied to a body or body part of a vertebral mammal is also disclosed.

Abstract: An exercise feedback system receives exercise data such as images or video captured by client devices of users performing exercises. The exercise feedback system may access a machine learning model trained using image of a population of users. The images used for training may be labeled, for example, as having proper or improper musculoskeletal form. The exercise feedback system may determine a metrics describing the musculoskeletal form of a user by applying the trained machine learning model to images of the user as input features. The exercise feedback system may generate feedback for a certain exercise using the metrics based on output predictions of the model. The feedback can be provided to a client device of the user or a physical therapist for presentation.

Abstract: An exercise feedback system receives exercise data captured by client devices of users performing musculoskeletal exercises. The exercise feedback system may provide captured images to a client device of a physical trainer (PT) who remotely provides feedback on the users' exercise performances, for example, by labeling images as indicative of proper or improper musculoskeletal form. A PT may track multiple users using a central feed, which includes content displayed in an order based on ranking of users by a model. Additionally, the exercise feedback system may provide an augmented reality (AR) environment. For instance, an AR graphic indicating a target musculoskeletal form for an exercise is overlaid on a video feed displayed by a client device. Responsive to detecting that a user's form is aligned to the AR graphic, the exercise feedback system may notify the user and trigger the start of the exercise.

Abstract: A marine vessel hull, and marine vessels comprising at least one such hue, comprising a non-entrapment hull having at least one longitudinally vented transverse step, each longitudinally vented transverse step comprising a transverse step, and one or- more longitudinal steps extending forward therefrom. Each longitudinal step portion has a cross-sectional profile defining a cutout into the hull relative to a line defined by a deadrise angle of the hull. The cutout defines a vertical rise starting from the line defined by the deadrise angle and a run tilted outwardly upward at a non-horizontal angle less than the deadrise angle and that extends to an intersection with the line defined by the deadrise angle.
