A ball, and in particular a baseball or softball, including one or more sensors such as accelerometers and/or inertial measurement units, and systems and methods using the same to improve a pitcher's pitching performance are described herein. In some embodiments, the ball may include one or more inertial measurement units and/or accelerometers capable of monitoring motion of the ball while it is thrown. Various types of pitches may be selected, and in response to the inertial measurement unit(s) and/or accelerometer(s) detecting certain parameters corresponding to a selected pitch, one or more indicators may be caused to perform an action. For example, one or more illuminating elements located on the ball may turn a first color in response to detecting parameters corresponding to the selected pitch.

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.

An iron-type golf club having selectively machined portions and attributes.

A method of providing feedback for a piece of cue-sport equipment, a cue ball or cue stick, during a game play first collect spatial positioning and orientation data from a plurality of measurement sensors that is integrated into the cue-sport equipment. Then, the collected data is analyzed to generate a virtual movement model of the cue-sport equipment as the virtual movement model includes a calculated impact force diagram, an animated travel path, and a calculated absolute orientation for the cue-sport equipment. Then, the player can view the virtual movement model through an external computing device to improve their cue-sport skills effectively and efficiently.

Wearable systems and methods to comprehensively analyze physical activity of a user for training and/or therapeutic purposes, by analyzing multiple channels of data about both muscle activity, using non-invasive surface electromyography (sEMG), and associated motion from that muscle activity, using inertial measurement units (IMU), are disclosed.

A computerized software system helps badminton players improve their footwork and conditioning. The system reads information from stored training modules in a portable computing device. In one mode, the system displays an indicator arrow to one of six corners on a badminton court image. A player moves on a real badminton court or other suitable surface in the direction indicated by the arrow displayed on the badminton court image. The arrow represents a fake and is displayed randomly or in sequence to all six corners. The speed the arrow flashes from corner to corner is adjustable. In another mode, the system randomly displays an indicator symbol on an opposing badminton court image to indicate an area of the court a player is to return a fed bird. A user may select a training module having either timed training sets or count training sets.

Systems and methods track a first object when continuous tracking information for the first object is not available. The systems and methods detect when the tracking information for the first object is not available. A last time of a last determined location of the first object is determined and a second object closest to the last determined location at the last time is determined. The location of the first object is associated with a location of the second object if tracking information for the first object is not available.

A method, system, and computer program for non-invasively monitoring a physiological parameter and providing biofeedback. The method, system, and computer program provide for the non-invasive detection of a physiological parameter by detecting changes in color channel values of a user in a live video feed and presenting biofeedback to the user indicating the relative position of the physiological parameter to an optimal range.

A system may comprise one or more monitoring devices that may communicate with a mobile device or a wearable device worn by a user of a sporting apparatus. The system may enable motion data specific to motion of the sporting apparatus to be conveniently captured and transmitted, and displayed on the wearable device. The system may include functionality to permit disablement of the motion detecting, transmission, and/or displaying functions at times when such functions are not permitted to be used, and to record the date, time, and location when such functions have been disabled to permit verification thereof by a governing body or sporting organization. The system may further include a learning module enabling monitored motion of the object to be correlated to monitored motion of the user such that predictive motion of the sporting object based only on monitored motion of the user may be obtained and displayed.

A multifunctional arm cranking exerciser includes an omnidirectional support bracket assembly, which comprises a five-way bracket mounted to a top thereof and having a left side to which a left arm exercising device is mounted and a right side to which a right arm exercising device is mounted. Also mounted on the five-way bracket are a damping adjustment device and a quick release pin device. The quick release pin device allows for quick coupling and positioning of left and right arm cranks of the left and right arm exercising devices at an angular difference of 0 degree or 180 degrees and also allows for quick release and decoupling of the left and right arm exercising devices to be independent of each other. The damping adjustment device adjusts and regulates a level of damping for achieving an effect of efficient exercising.
