A system for monitoring performance of a user includes at least one processor, and at least one memory including a computer program code. The at least one memory and the computer program code are configured, with the at least one processor, to cause the system to perform operations including obtaining force data measured by at least one force sensor coupled with one or more poles and velocity data measured by at least one sensor for measuring velocity of the user, determining poling power based on the force data and the velocity data, and outputting a poling power indicator based on the determined poling power.

A clamping apparatus (1) for a pole for axially fastening in a releasable manner an inner pipe segment (3) that can be inserted into an opening of the clamping apparatus. The clamping apparatus comprises a two-part plastic sleeve (5), which can be fastened to an outer pipe segment (2). The clamping apparatus also comprises a slotted clamp (16), which surrounds and clamps the plastic sleeve and which has a clamping lever (4), a lever arm (9) of which has an eccentric rolling region (8), by which the distance between a stop (12) and a counter surface (27) arranged on the outside of the first projection (13) can be reduced for clamping by pivoting the clamping lever (4) into the closed position.

Training equipment includes a hollow shaft having a sidewall defining an internal cavity and at least one polymer material filling at least a portion of the internal cavity. The polymer material may fill the entire internal cavity of the hollow shaft. The polymer material may be a visco-elastic polymer material or polyurethane. A spacer or a filler may fill at least a portion of the internal cavity. A method of making weighted training equipment with a hollow shaft having a sidewall defining an internal cavity may include injecting a curable composition into at least a portion of the internal cavity. The method may further include curing the curable composition into a polymer material.

A plastic composite component which is formed by a thin hard plastic outer layer, at least one elastomer layer adjoining the former on the inside, and at least one metal and/or plastic carrier layer adjoining said elastomer layer on the inside and made of a fibre reinforced plastic (RFP). A carbon fibre reinforced plastic (CRP) or glass fibre reinforced plastic (GRP), is arranged on the component or at least partly forms the latter, as an impact protection part, as a splinter protection part, as a protective part against sudden total failure or as a protective part against vibrations and vibration damages, against resonance, for the purpose of damping oscillations or for the purpose of acoustic damping.

The invention relates to a navigation device, preferably for a two-wheeled vehicle, for attachment in a handlebar pipe, characterized in that the navigation device has at least the following components: at least one communication device for generating a haptic and/or acoustic ad-hoc navigation instruction for perception by a human user; and an insertion section, wherein the insertion section has a maximum external dimension, with the result that the insertion section can be introduced into a pipe. With the invention presented here, a user can be reliably navigated through traffic without visual contact.

The present disclosure presents a multi-purpose pole grip design in a generally conical shape to resist a user's hand from sliding off it while under axial loading. The present disclosure provides a more ergonomic and comfortable handle that requires less grip strength thus making it a prime design for poles used in sports like skiing and hiking and general walking sticks, including canes.

A pole comprising a pole handle and a pole tip, with at least two tube portions located therebetween, which in an assembled state of the pole are connected to one another by means of insertion connections aligned along a longitudinal pole axis A. At least one of the plug connections is realized on a second tube portion by way of a form-fit and/or force-fit locking device, wherein the second tube portion has a smaller the same outer diameter than the inner diameter of a first tube portion, and which can be inserted into the first tube portion, and which can be fixed in the relative axial position by means of the form-fit locking device. On at least one of the plug connections, a tubular sleeve having a clamping element in a receiving groove is arranged between the tubular sleeve and the lower end of the first tubular portion.

Tip attachment for a pole, in particular for a trekking pole, cross-country-skiing pole, Nordic-walking pole or downhill-skiing pole, having a plastic sleeve, which can be fastened at the lower, free end of a pole tube and, at an upper end, has an upwardly open hole for accommodating the lower, free end of the pole tube, and a tip insert is fastened in an opening at the lower end of the pole tube. The tip insert has a carrier element, which is releasably fastened in the opening by a drive-in thread provided on a retaining region in a substantially cylindrical region.

The present invention relates to a sport stick that measures the driving force generated by the upper body, which is applied to the ground through poles during the natural performance of nordic walking or any other sport, where poles are used to drive/propel the body forward. An inclination sensor along with a pole length sensor (pole length constant in a fixed length pole) has been placed into the pole for the achievement of the most suitable biomechanical performance, i.e. proper technique. The sport pole uses the Global Positioning System along with a topographical map to ensure that the slope of terrain does not affect the inclination sensor measurements. All collected data is analyzed by a control center, wherein correct usage models have been saved along with a collection of the user's anthropometric and fitness levels.
