An active suspension orthotic support system is disclosed. The suspension orthotic support system comprises at least one variable resistance beam extending from a heel section to a mid-arch section of the footwear, wherein rotation of the variable resistance beam from a first position to a second position causes a resistance provided by the variable resistance beam to vary between a minimum resistance to a maximum resistance.

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 improved golf swing training device that includes a curved platform with right and left adjustable strike plates, each having adjustable swing plane guide rods connected by a rotating disk attached to the rear of each strike plate. The curved platform, duplicating the bottom path of the proper curved golf swing, is attached to a single straight track by means of multiple horizontal bearings. The curved platform moves fore and aft along the straight track. The bearings provide both retention and backstroke/reverse and follow-through/forward movement of the curved swing platform. The elongated and angled strike plates with the extended guide rods guide the club through backswing and follow-through. Adjustable resistance can be added to the curved platform to assist strength training.

A practice putting device that includes a rollable putting mat, a housing, and ball return arrangement.

The present invention provides a putting guide capable of correcting a posture when putting, checking a contact angle between a putter and a golf ball, correcting a posture of an exerciser during a putting practice, and checking a focusing point that the exerciser watches.

The putting guide for putting practice includes a hitting part, a rod part connected to the hitting part, and a front part formed on an end of the rod part.

Systems and methods are disclosed for generating a 3D avatar and object fitting recommendations using a biomechanical analysis of observed actions with a focus on representing actions through computer-generated 3D avatars. Physical quantities of biomechanical actions can be measured from the observations, and the system can analyze these values, compare them to target or optimal values, and use the observations and known biomechanical capabilities to generate the 3D avatars and object fitting recommendations.

An adjustable laser-sensor paired system for creating or replicating a desired swing form includes a laser device and a sensor device. The laser device has a laser which emits a laser beam and a mounting device which attaches the laser device to an object. The orientation of the laser is adjustable. The sensor device has an optical linear position sensor for detecting the laser beam of the laser device and a display with LEDs for providing feedback and user interface. With the system and method, one or more checkpoints for the form of a desired swing can be created at a selected point in the swing path, which may then be used as practice reference guides to check whether the user is correctly replicating the desired swing.

An adjustable height golf tee system having a tee and an anchor is discussed. The tee is height-adjustable relative to the anchor. A first anchor includes a cap, a stem, and a tip. The stem can be threaded internally, externally, or a combination thereof. A second anchor includes a base, a first stem, a cap, and a second stem as well as optional spacers. The stems can be threaded internally. Both the first and second anchors can be composed multiple pieces (e.g., a detachable cap, a detachable stem, or a detachable portion thereof) to provide access to an inner cavity of the respective stems.
