A load measurement device includes an acquisition unit, a first extraction unit, a second extraction unit, and an output unit. The acquisition unit acquires measurement information output from a load distribution sensor that detects a load distribution received from a sole of a subject. The first extraction unit extracts a region having a load value equal to or larger than a first threshold value as a first region based on the measurement information, and detects the first region as a sole region. The second extraction unit extracts a second region having a load value equal to or larger than a second threshold value that is smaller than the first threshold value from a re-extraction target region defined with the first region as a reference, and adds the second region to the sole region. The output unit outputs information related to a load distribution of the sole region.

A walking training system includes a leg orthosis fitted to a leg of a user, a pulling member coupled to the leg orthosis, a first drive mechanism configured to apply pull force to the pulling member, according to walking motion of the user, a holding device that holds the pulling member at a holding level, at a point between a coupling point of the leg orthosis and the first drive mechanism, and a second drive mechanism configured to change the holding level of the pulling member held by the holding device, according to the walking motion of the user.

A method and system for indicating a breathing pattern is disclosed. The system comprises a plurality of smart wearable devices, a plurality of mobile devices, an application server and a database. The plurality of smart wearable devices is either connected to the mobile devices or directly connected to the application server. The database is connected to the application server to store the data transmitted by the smart wearable device or the mobile device. The plurality of smart wearable devices is capable of monitoring the health index and identifying the variation in health conditions of the user, in real-time and activating a suitable breathing pattern to normalize such medical condition.

An interior bike system includes: an interior bike including a rotational angle detection sensor sensing a pedal rotation angular speed; a motion recognition sensor recognizing a head or upper body motion of a player; a heart rate measurement sensor measuring a heart rate of the player; a controller receiving and transferring sensing signals of the rotational angle detection sensor, the motion recognition sensor, and the heart rate measurement sensor to a web server; the web server determining whether performing the task motion given to the player is successful based on the signal of the motion recognition sensor of the controller, and generating a content image to which whether the player succeeds in performing the task motion is reflected and transmitting the generated content image to the content controller; and a display unit displaying an image transmitted from the web server through the controller.

The present invention provides system and method for tracking and analyzing golf shot, the method comprising: turning on a light source; a capturing a pair of images of the golf shot using a pair of stereo cameras having a same focal length and triggered by single signal; a analyzing a disparity between the pair of images; a producing a disparity map, a three dimension simulation, and a first motion analysis data; a capturing an image of the golf shot from before to after contact between a golf club and a golf ball using a single camera; a analyzing image sequences captured by the single camera; a producing a second motion analysis data including at least one of ball spinning, club face angle, and swing, and displaying the three dimension simulation, the image sequence, and the first and the second motion analysis data.

An adjustable weight exercise system is provided. A permanent weight assembly and a plurality of interlocking weights are provided. A base comprises an interlocking weight carrier, wherein the interlocking weights are supported on the interlocking weight carrier and an interlocking weight selector, wherein the interlocking weight selector is adapted to cause interlocking weights to be set to be locked to the permanent weight assembly while the permanent weight assembly is not on the base, wherein placement of the permanent weight assembly on the base causes interlocking weights that are set to be locked to the permanent weight assembly to be locked to the permanent weight assembly, and wherein placement of the permanent weight assembly on the base does not cause interlocking weights that are not set to be locked to the permanent weight assembly to be locked to the permanent weight assembly.

An Internet of Thing (IoT) device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

Systems and methods for tracking a sports ball assembly in real time during a sporting event are disclosed. A structure of the sports ball assembly is also disclosed. The sports ball assembly comprises at least one electronic circuit embedded or attached to a sports ball. The sports ball assembly is in network communication with a processor via at least two receivers within a sports arena. The sports ball assembly generates and transmits UWB data packets comprising movement-related data for the sports ball assembly in real time at a predetermined rate. The at least two receivers receive the UWB data packets and transmit to the processor with time stamps. The processor is operable to determine a movement of the sports ball assembly based on the UWB data packets and the time stamps received from the at least two receivers.

An arrangement for aligning a pair of game boards as used in a tossing game such as cornhole, the arrangement including alignment fiducials located along a center line of each game board and an alignment system that uses a marking line that uses the fiducials to achieve alignment (and perhaps also proper spacing) between the pair of game boards. The marking line of the alignment system may be either a laser-based source or a non-elastic weighted string source.

A laser mandrel system that self-centers within a hosel bore of a golf club head to allow for precision adjustment of lie and loft is disclosed herein. The mandrel includes a one-piece housing with upper and lower portions, a laser centered within the upper portion of the housing, and a plurality of o-rings extending around an exterior or interior surface of a lower portion of the housing.
