And water sealing tips disposed interior of the earphones, the tips preserving the audio quality of the earphones when worn in an aquatic or semi-aquatic setting by a prospective user.

A walking training system includes a treadmill, a center-of-gravity position detection unit that detects a center-of-gravity position of a trainee from a load received from a sole of the trainee on a belt of the treadmill, a posture detection unit that detects a posture of the trainee, a center-of-gravity position estimation unit that estimates the center-of-gravity position of the trainee from the detected posture of the trainee, a determination unit that determines whether a difference between the detected center-of-gravity position and the estimated center-of-gravity position exceeds a predetermined value, and a notification unit that sends, when the determination unit determines that the difference exceeds the predetermined value, a notification notifying that whether the difference exceeds the predetermined value.

An intelligent system that automatically adjusting optimal rehabilitation intensity or exercise volume with personalized exercise prescription, comprising: upload the physiological information data measured by registered members to a cloud data integration server through the Internet; an expert diagnostic unit, which can download and use the member's physiological information data from the cloud data integration server. After the diagnosis, a personalized exercise prescription is issued and uploaded to the cloud data integration server; a rehabilitation fitness equipment unit can download the exercise prescription from the cloud data integration server to control and automatically adjust the optimal rehabilitation intensity or exercise volume; after being diagnosed by experts such as doctors, rehabilitators or fitness coaches, the optimal parameter values of a continuously updated artificial intelligence exercise prescription can be used to improve the efficacy of personal rehabilitation or exercise fitness.

A walking state measurement system includes: an endless belt that defines a walking surface on which a subject walks and that travels along a walking front-rear direction; a marker provided on at least the walking surface along a circumferential direction of the belt; a first camera for taking an image of the subject from front, the first camera taking an image of the marker on the walking surface from above to generate a first image; a second camera for taking an image of the subject from front, the second camera taking an image of the marker on the walking surface from above to generate a second image; and a correction processing unit that corrects an image generated by at least either the first camera or the second camera based on a position of an image area of the marker included in each of the first image and the second image.

A treadmill having novel rapid assembly and safe storage features is provided. The treadmill includes a support base, a platform, a pair of upright arms, and a top assembly including a bridge connected to an upper and a lower handrail, the lower handrail includes a bottom portion having pivot flanges, each pivot flange has a first aperture therethrough and a bracket has a second aperture therethrough. A second pivot fastener is installed to connect and attachment tang on the upright arms with the pivot flange of the top assembly. The upright arms and the top assembly can each be rotated a predetermined angle for fixed installation of the upright arms and top assembly with respect to the long axis and platform.

There is provided a method and apparatus for tracking a device. The tracked device may be a wearable device worn by a user participating in an athletic activity. An anchor device is positioned with respect to a playing area and receives signals from the tracked device. The anchor device estimates the position of the tracked device by measuring a distance and direction of the signal, and decodes the signal to obtain measurements taken by the tracked device. The position and the measurements are combined to produce tracking data for the device.

An exercise system includes a workout server. An active workout session is created for a user on the workout server. An exercise information is collected for a user at a first exercise device and a second exercise device. The exercise information is tracked to the active workout session and maintained on the workout server. This allows a user to maintain a workout session across multiple devices.

An apparatus and method for determining a stimp rating of a golf putting green surface. The stimp device measures distance traversed over a horizontal surface through a rotary encoder with a predetermined force applied to calculate the Stimp rating of the surface. A microprocessor automates the process and the calculation and communicates the results to the user via a display or wireless communication with a mobile computing device.

A method of customizing a golf club, wherein the method includes generating operating data representative of a user operating a mechanical device. The operating data is generated by a first sensor sized and configured to be removably positioned in a mounting port formed on the mechanical device during operation of the mechanical device. The sensor is interchangeably positionable in the mounting port with at least one mass insert, the at least one mass insert being adapted to be interchangeably positioned in the mounting to provide at least two different mass configurations. The method further includes determining a recommended configuration of the at least one mass insert specific to the user based on the operating data generated by the sensor, and transmitting information representative of the recommended mass insert.

The device comprises a belt (3) on which is mounted a first sensing module (4), with: a) a hitch (6) for connecting a recovery component part (7) such as a spring; b) a first movement sensing unit (8) to detect 3D movement; c) a force sensing unit (9) to detect the force exerted by the recovery component part (7) upon the hitch (6); in which the movement and force data are processed and sent wirelessly via a data transmission unit (11); and d) first means of closure (13,14), to close the belt (3) to a required dimension. Allows simultaneous and coordinated consideration of force and movement data.
