A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

A pelvic floor muscle training device includes a pelvic floor muscle training device, an intelligent terminal, a cloud server, a VR device, and one or more application programs. The user does Kegel exercise wearing the training device, with the help of the VR device and scene induction, synergistic or independently, thus enhancing pelvic floor muscle function.

There is provided herein circuitry and methods for applications including touch detection and, in embodiments, low rate communication such as for secure device authentication. The method uses a circuit having a first device having a first pair of unconnected plates and an edge source coupled therebetween. The circuit further comprises a second device having a second pair of respective unconnected plates and a charge sensor coupled therebetween. The method for touch detection comprises applying at least one differential edge between the first pair of unconnected plates using the edge source and detecting touch by coherently (i.e. in time) sensing an imbalance in a near field channel formed between the plates and an output signal of the charge sensor. The present method/circuit has various applications including for touch detection in fencing and secure device authentication employing both touch detection and bidirectional cryptographic communication between key and secure devices.

A system for dynamic movement scoring comprising an article of footwear or apparel and a processor in networked wireless communication with the article of footwear or apparel. The article includes at least one accelerometer or inertial measurement unit operative to monitor spatial motion of at least a portion of the article of footwear or apparel, and to generate a data stream indicative of the monitored spatial motion. The processor is configured to receive the data stream from the article of footwear or apparel, identify at least one motion primitive from the received data stream; and determine an accuracy metric representing a correspondence between the monitored spatial motion of the article of footwear or apparel and the ordered number of motion primitives.

A system for motion-based media creation includes an article of footwear or apparel having at least one accelerometer or inertial measurement unit operative to monitor spatial motion of at least a portion of the article of footwear or apparel and generate a data stream indicative of the monitored spatial motion. The system further includes a processor in networked wireless communication with the article of footwear or apparel. The processor is configured to receive the data stream from the article of footwear or apparel; identify at least one motion primitive from the received data stream; and trigger the playback of an audio sample or a visual effect in response to the identified at least one motion primitive.

A golf putting game includes at least one putting green defining a putting surface and a plurality of putting cups disposed within the putting surface at a different location on the putting green. Each putting cup has an exterior housing and an interior core disposed within and removably attached to the exterior housing. The interior core is removable from the exterior housing with the putting cup disposed within the putting surface of the putting green. Each putting cup is illuminated by a different predetermined color and assigned a different predetermined number of base points corresponding to the predetermined color. A player score is determined from a number of putting strokes made by a player to putt a putting ball into the putting cup and the predetermined number of base points assigned to the putting cup.

The information processing apparatus generates three-dimensional shape data representing a three-dimensional shape of a first object by using a plurality of images obtained by a plurality of imaging apparatuses capturing the first object. The information processing apparatus estimates a size of the first object by using the three-dimensional shape data. The information processing apparatus specifies a position of a second object that is captured by the plurality of imaging apparatuses based on results of a comparison between the estimated size of the first object and a predetermined reference value.

Methods and systems for use in automating or assisting umpiring of a baseball or softball game are described herein. A location of a strike zone is determined based on video images of a batter standing next to home plate captured by a camera. Locations of a ball traveling towards the batter, and locations of the bat being held by the batter, are autonomously tracked using computer vision based on video images captured by at least two cameras having different positions. Additionally, there are autonomous determinations of whether a location of the ball intersects with the strike zone, and whether the batter made a genuine attempt to swing the bat at the ball, and based one at least one of these determinations, there is an autonomous determination of whether a “strike” or a “ball” occurred. Additionally, an indication of whether a “strike” or a “ball” occurred is autonomously output.
