A sensor device includes an inertial sensor and a holding member. The holding member holds the inertial sensor and is capable of being attached to and detached from an end face of a grip being part of a sports implement and having the shape of a shaft. The holding member includes a sensor-side coupling part. The sensor-side coupling part is capable of being attached to and detached from a grip-side coupling part on the end face of the grip by being moved relative to the grip in a first direction that forms an angle with an axial direction of the grip.

A racquet including a tubular frame formed of a fiber composite material, a pallet and a butt cap. The frame includes first and second end regions and a mid-region. The handle portion includes a distal region, proximal region and a central region positioned between the distal and proximal regions of the handle portion. The central and proximal regions of the handle portion have outer surfaces that define first and second transverse cross-sectional areas, respectively. The second transverse cross-sectional area is larger than the first transverse cross-sectional area. The pallet is coupled to and longitudinally extends over the central region but not over the proximal region of the handle portion. The butt cap is secured to the proximal region and includes a peripheral wall and less than half of the length of the peripheral wall extends over the pallet.

An endcap system for a sporting implement includes a base portion and a transverse extension projecting from the base portion. The base portion has a bottom surface with a central axis normal thereto. A receptacle opposite the bottom surface is configured to receive a portion of the sporting implement. The extension is configured such that, during swinging of the sporting implement with a hand of a user gripping around the sporting implement portion, the extension contacts an exterior lateral portion and upper portion of a fifth metacarpal of the hand and the hand is constrained in both the transverse and longitudinal aspects while being allowed rotation of a first metacarpal of the hand away from the central axis.

Devices systems and methods are disclosed. Among other things, the devices systems and methods can facilitate ergonomic gripping of a handle; conform to the shape of a wrist; enhance golf techniques or performance; enhance racket sport technique or performance; protect a head of a user engaged in contact sports or other hazardous activities; identify concussions, in some cases in substantially real time; provide sterilization of garments; control surgical robots; allow for medical treatment of multiple subjects without disrobing; provide biometric or other data; and/or be used to train muscles or body parts for, for example, performing specified tasks using a body part.

There is herein described a range of sporting products comprising sucker elements, which can be used in various uses such as on products which require, for example, hand or any other type of grip contact. The grip contact may be with the feet or hands (or any other part of the body). The sporting products that the grips may be used on may comprise rackets (e.g. for tennis/badminton/squash etc.), bats (e.g. cricket/baseball/table-tennis etc.), bicycles, motorcycles, golf clubs, water sports (surfing, windsurfing) etc. The sucker elements may also be included with other sporting product such as on the inside and/or outside of running sock or shoes for example. There is also described a range of industrial products comprising sucker elements which can be used in a range of applications such as on a range of vehicle parts (e.g. bus rails, train rails, boat rails, steering wheels, motorbike handles and foot pegs etc.), industrial machinery (e.g. handles for tools such as drills, pneumatic drills etc.), flooring (e.g. decking on boats and in industrial environments), crockery, bathroom and shower flooring, and surfaces to aid disabled people.

A tennis racket with a more-responsive string configuration is an apparatus that allows a user to hit a tennis ball with spin and power in a controlled manner. The apparatus includes a closed-shape beam, a throat, an elongated handle, and a plurality of lines. The elongated handle allows the user to firmly grasp the apparatus, and the throat connects the elongated handle to the closed-shape beam. The plurality of lines is tensionably mounted within the closed-shape beam in order to provide the present invention with an elastic contact area for the tennis ball. Each of the plurality of lines includes a first string and a second string, which are positioned along each other for each of the plurality of lines. In addition, a lateral surface of the first string is positioned tangent to a lateral surface of the second string.

A universal swing training apparatus is provided that includes a sports-related implement and a slide mechanism. The implement includes a proximal section and a distal section that are spaced apart to form a gap there-between. The slide mechanism is inserted within this gap and is connected to the upper end of the proximal section and the lower end of the distal section. The slide mechanism includes a rail guide, a plurality of front ball bearings, a plurality of rear ball bearings, and a sliding rail assembly that are cooperatively configured to insure that this upper end and this lower end are coaxial when the sliding rail assembly is situated in a coaxial position on the rail guide, and permit a lateral shift of this lower end relative to this upper end during a swinging of the implement.
