A golf club having a sensor that is removably connected at one or more positions of the golf club where the sensor comprises an inertial measurement unit including an accelerometer capable of measuring linear accelerations in three orthogonal axes and a gyroscope capable of measuring an angular rate of rotation around the same axes. The sensor may further comprise a processor which may perform instructions to detect the impact of the golf club with a golf ball and determine the start of the golf swing without any additional input from the user. The sensor may further have a power management system to extend the life of the power source.

A tower may support a horizontal track and a vertical climbing wall therebelow. A trolley, movable along the track, may be selectively driven toward and away from the tower by belay lines, line and capstan, positive drive, or some combination. Belay lines reeved over pulleys on the trolley may be taken up and paid out independently from the trolley, while fixed or moving. A rider may climb, be lifted, or both to near the intersection of the tower and track, from there to fall or jump into a controllable trajectory such as swinging or simulating a parachute landing. Swinging may be rapidly attenuated almost entirely by “bumps,” lifting a rider to remove momentum and kinetic energy as a rider moves toward a pivot point overhead. Control may be simplified based on sensing and using timing past bottom dead center (BDC).

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.

The present disclosure relates to a method for measuring a speed of a sports device. The method includes: acquiring movement data of the sports device during a process of tracking the sports device, the movement data being collected by a sensor disposed at a bottom of the sports device; calculating a linear speed and a rotational speed of the sports device based on accelerations of three axes in the movement data; and combining the linear speed and the rotational speed to obtain a movement speed of the sports device. In addition, the present disclosure also provides an apparatus for measuring a speed of a sports device, which corresponds to the above method. The method and the apparatus for measuring a speed of a sports device can improve the credibility of the speed measurement of the sports device.

A method is provided for detecting at least one fitness related activity is provided. Data is obtained from at least one sensor of a wearable device, wherein the at least one sensor detects the data based on at least one body movement of a user wearing the wearable device. Based on the obtained data, the at least one fitness related activity is detected from a set of fitness related activities, wherein the detection is performed without pre-training by the user for the detecting.

A method and system for using a low resolution image of a golfer's swing for analysis is disclosed. Cameras obtain images of various portions of a golfer's swing. A computer calculates parameters associated with a golfer and a golf club from the images. Parameters include body angles, head position, shoulder positions, arm positions, hand positions, leg positions, foot positions, club shaft angles, and club head position. Different portions of the swing are captured using the cameras, including a static initial address, a backswing, a downswing, a forward swing, and a follow-through. A computer uses measured parameters from two or more portions of the swing to determine comparative parameters during different portions of the swing. The computer uses the parameters to generate swing analysis outputs, including swing characteristic information and/or swing profile information. A correlation table relates identified swing analysis outputs to particular recommendations to the golfer to improve the swing.

The present invention is directed towards a putting stroke analysis device for analyzing a putting stroke technique of a golfer. The putting stroke analysis device comprises a planar surface with a plurality of infrared emitters and co-operating infrared sensors thereon. A golfer swings their putter over the planar surface, above the plurality of infrared emitters and co-operating infrared sensors. An infrared beam, emitted by the infrared emitters, is reflected by the putter and is detected by one or more of the infrared sensors. The putting stroke analysis device has a processor which receives information from the co-operating infrared sensors and processes the information to determine putting characteristics of the putting stroke technique. The putting characteristics include, but are not limited to, speed of putter head, velocity of putter head, acceleration of putter head, speed of golf ball, velocity of golf ball, acceleration of golf ball, swing path of putter head, angle of attack of putter head, angle of putter head at impact with a golf ball, and, impact point on a putter face of the putter head at impact with a golf ball.

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.
