Patent number: 12008772Abstract: This disclosure is directed to a method and system for matching human pose data in the form of 2D skeletons for the purposes of 3D reconstruction. The system may comprise a scoring module that assigns an affinity score to each pair of cross-view 2D skeletons, a matching module that assigns optimal pairwise matches based on the affinity scores, a grouping module that assigns each 2D skeleton to a group such that each group corresponds to a unique person, based on the pairwise matches; and a temporal consistency module that assigns each group an ID that maintains correspondence to the same person over the multi-video sequence.Type: GrantFiled: March 20, 2020Date of Patent: June 11, 2024Assignee: HINGE HEALTH, INC.Inventor: Wenxin Zhang

Patent number: 11948252Abstract: An apparatus is provided. The apparatus includes a communications interface to receive raw data from an external source. The raw data includes a representation of an object. Furthermore, the apparatus includes a memory storage unit to store the raw data. The apparatus also includes a pre-processing engine to generate a coarse segmentation map and a joint heatmap from the raw data. The coarse segmentation map is to outline the object and the joint heatmap is to represent a point on the object. The apparatus further includes a neural network engine to receive the raw data, the coarse segmentation map, and the joint heatmap. The neural network engine is to generate a plurality of two-dimensional maps. Also, the apparatus includes a mesh creator engine to generate a three-dimensional mesh based on the plurality of two-dimensional maps.Type: GrantFiled: October 29, 2020Date of Patent: April 2, 2024Assignee: HINGE HEALTH, INC.Inventors: Sohail Zangenehpour, Colin Joseph Brown, Paul Anthony Kruszewski

Patent number: 11875529Abstract: Systems and methods are provided for estimating the 3D joint location of skeleton joints from an image segment of an object and a 2D joint heatmaps comprising 2D locations of skeleton joints on the image segment. This includes applying the image segment and 2D joint heatmaps to a convolutional neural network containing at least one 3D convolutional layer block, wherein the 2D resolution is reduced at each 3D convolutional layer and the depth resolution is expanded to produce an estimated depth for each joint. Combining the 2D location of each kind of joint with the estimated depth of the kind of joint generates an estimated 3D joint position of the skeleton joint.Type: GrantFiled: June 1, 2022Date of Patent: January 16, 2024Assignee: HINGE HEALTH, INC.Inventors: Colin Brown, Louis Harbour

Patent number: 11801383Abstract: Neuromodulation devices and methods of their use are described in which a therapeutic device is configured to generate a treatment for treating pain such as the reduction of the symptoms of chronic and acute pain as well as for treating other conditions. The neuromodulation device generates an output electrical signal in the form of pulses with a fast rise-time spike waveform followed by a longer-duration, lower amplitude primary phase waveform. The output signal includes a broad range of frequency components, with time constants tuned so as to interact with specific cell membrane or cellular components. The output signal may be conducted to the patient via electrodes. The pulses are triggered at variable intervals which prevent habituation.Type: GrantFiled: September 21, 2020Date of Patent: October 31, 2023Assignee: Hinge Health, Inc.Inventors: Alexander B. Izvorski, Shaun Rahimi, Kevin McCullough

Patent number: 11783183Abstract: An activity classifier system and method that classifies human activities using 2D skeleton data. The system includes a skeleton preprocessor that transforms the 2D skeleton data into transformed skeleton data, the transformed skeleton data comprising scaled, relative joint positions and relative joint velocities. The system also includes a gesture classifier comprising a first recurrent neural network that receives the transformed skeleton data, and is trained to identify the most probable of a plurality of gestures. The system also has an action classifier comprising a second recurrent neural network that receives information from the first recurrent neural networks and is trained to identify the most probable of a plurality of actions.Type: GrantFiled: February 11, 2021Date of Patent: October 10, 2023Assignee: HINGE HEALTH, INC.Inventors: Colin J. Brown, Andrey Tolstikhin, Thomas D. Peters, Dongwook Cho, Maggie Zhang, Paul A. Kruszewski

Patent number: 11657281Abstract: This disclosure describes an activity recognition system for asymmetric (e.g. left- and right-handed) activities that leverages the symmetry intrinsic to most human and animal bodies. Specifically, described is 1) a human activity recognition system that only recognizes handed activities but is inferenced twice, once with input flipped, to identify both left- and right-handed activities and a training method for learning-based implementations of the aforementioned system that flips all training instances (and associated labels) to appear left-handed and in doing so, balances the training dataset between left- and right-handed activities.Type: GrantFiled: March 12, 2020Date of Patent: May 23, 2023Assignee: Hinge Health, Inc.Inventors: Colin Brown, Andrey Tolstikhin
