A system and methods for custom-fitting golf clubs and golf club components is disclosed. Data is generated by a tracking device as a plurality of golf swings are performed by an individual. The data comprises motion and orientation information associated with a golf ball and with a golf club. The data is displayed using a graphical user interface. A plurality of shot characteristics is determined from the data. The shot characteristics are used to recommend golf clubs and golf club components that adjust a golfer's swing where the golfer exhibits the plurality of shot characteristics.

A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

There is described an integrated unweighted gait training system having an unweighting system comprising a computer controller; a gait measurement system in communication with the controller; and a display in communication with the computer controller adapted and configured to provide real-time feedback to a user of the integrated unweighting gait training system. The unweighting system may be a differential air pressure (DAP) unweighting system or a non-DAP unweighting system.

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.

An embodiment of an exercise monitoring apparatus is shown. Herein, the exercise monitoring apparatus comprises a casing, a fastening member, a first laser device and a second laser device. The first laser device is oriented so that, when actuated, the device outwardly projects a first light beam in a direction substantially perpendicular to a top surface of the casing. The first light beam visually produces a line of light. The second laser device is oriented so that, when actuated, the device outwardly projects a second light beam in a direction substantially perpendicular to one of the sidewalls of the casing and substantially perpendicular to the first light beam.

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 low-cost balance exerciser for use at work includes a central support for a ball joint disposed on a base, an inflatable elastic toroidal bladder disposed on the base and centered about the central support, a rigid circular balance platform whose center is fixed to the ball joint on its lower surface, and a pump connected to the inflatable elastic toroidal bladder.

A method for controlling breathing of a user during workout with an exercise machine is provided. The method includes acquiring, by a data processing unit of the exercise machine, at least one parameter representative of a physical exercise being performed by the user with the exercise machine, determining, by the data processing unit of the exercise machine, an indication of the breathing to be followed by the user while performing the physical exercise based on the acquired at least one parameter representative of the physical exercise, and providing the user, by the data processing unit of the exercise machine, with the determined indication of breathing. An exercise machine implementing the method for controlling breathing of the user during workout is also provided.

A shaft for a golf club includes a first end, a second end, and a demarcation. The first end is adapted to attach to a club head. The second end is adapted to receive a grip distal to the first end. The demarcation is positioned at or adjacent to the balance point of the golf club between the first end and the second end.
