The present invention measures jump heights using an IMU sensor module slipped in a pocket of a removable side ankle mount clip placed over any low, mid or high tops ankle athletic running shoe. A micro-processor in the IMU sensor module converts analog jump height data collected with real time digital signal processing to digital data sent to specialized algorithms loaded in a RF paired smartphone to refine the digital data to accurately calculate the height of the jump. The clip has two downward spaced legs joined by a curved arch at the top with a first leg being flexible and fitting snugly against a wearer's ankle below the fibula bone with the curved arch resting over the shoe's collar. The second leg has a foot extending outwardly from the curved arch to form a pocket with a top opening to receive and snugly hold the module.

A system and method for providing neurological function analysis and treatment to a person using virtual reality systems. The system and methods comprise a data capture system that receives, fuses, and integrates sensor data from various sensors, a virtual reality engine which uses the integrated sensor information to generate an environmental model and a tracking model, and a therapeutic engine which can assess both the cognitive and physical condition the person, determine a training regime based on the assessment, and apply therapies while the person is engaged in a virtual reality environment. The training regimen can comprise brainwave entrainment and/or dual-task stimulation via virtual elements. In some embodiments, a medical professional may engage with the person in the virtual reality environment.

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.

A system and method for human motion detection and tracking are disclosed. In one embodiment, an optical sensing instrument monitors a stage. A memory is accessible to a processor and communicatively coupled to the optical sensing instrument. The system captures a depth frame from the optical sensing instrument. The depth frame may include at each image element first coordinate values including a point related to a distance from the optical sensing instrument. The depth frame is converted into a designated depth frame format, which includes at each image element second coordinate values relative to the depth frame. Probability distribution models are applied to the designated depth frame format to identify a respective plurality of body parts. The position of each of the respective plurality of body parts in the designated depth frame is calculated as is the position of each of the plurality of body parts in the depth frame.

An apparatus, method, and system for measuring a golf club swing motion, especially a golf putting stroke, from the overhead view and enabling to provide in-situ athletic training and instruction along with analysis of the putting stroke by using augmented reality superimposed on the image of the actual golf club. The system comprises a portable apparatus, mobile device application interface, image processing algorithms and network servers. The portable apparatus includes a mini-camera and communication modules for capturing the video image of a putting stroke and transmitting the image via wireless, Wi-Fi, Hotspot, or Bluetooth to a designated electronic display device such as a tablet, mobile phone, or laptop. The portable apparatus is fixed to a fastening clip which fits easily onto a golf cap to provide the overhead view of the putting stroke and record the image from an actual golf course.

A system includes a processor configured for leveraging reference ball flight data associated with an individual and a reference club having a reference loft angle to compute predicted ball flight characteristics for other candidate golf clubs having loft angles different from the reference loft angle. The predicted ball flight characteristics include predicted distances of golf shots the individual is expected to make using the candidate golf clubs that can further accommodate a computed recommendation of optimal loft angles for a consistently gapped golf club set.

Methods, systems, and apparatus, including computer programs encoded on computer storage media, coordinate dynamic adjustments of a trailer based in part on a user profile associated with a user physically present at the trailer and an activity profile associated with an activity selected to be performed at the trailer. A dynamic adjustment may modify a tilt of a lower surface of the trailer. A dynamic adjustment may modify a dimension(s) of the trailer based in part on a detected object(s). Various dynamic adjustments may occur concurrently, individually and/or sequentially. The trailer may be a moveable trailer for temporary attachment with a vehicle.

Described herein are platforms, systems, media, and methods for providing golf swing analysis and coaching by receiving a video of an individual performing a golf swing; applying an image processing algorithm to identify a plurality of body nodes of the individual in a plurality of frames of the video and generate a virtual skeleton by connecting the plurality of body nodes in the plurality of frames of the video; identifying a plurality of key frames of the video; applying at least one mathematical swing flaw evaluation to each key frame of the video to identify any swing flaws of the individual; generating a swing score for the individual; and providing access to one or more training modules based at least on any swing flaws of the individual identified and the swing score for the individual.

A method includes identifying a first point on an object striking element in a first image and a second image from images. The first and second images are captured within a predetermined time span of an impact of the object with the element and determining an impact time of the impact in combination with determining a position in the first and/or second images corresponding to a location of the object at the impact time. Based on the positions of the first point in the first and second images, determining a position in the first and/or second images corresponding to a position of the first point at the impact time. The method also includes determining a distance from the imager to a location at which the object and the element impact one another and determining an impact location of the object relative to the first point.
