A system, method and apparatus for a digitally Controlled Variable Stiffness item of athletic equipment, such as a Ski, Snowboard, and Boots. A core of thermally responsive metal alloy, such as Nitinol is disposed within the athletic equipment. A thermal control module and controller permit the athlete to program the athletic equipment to a desired stiffness parameter. The controller may include an app operable via a mobile computing device in communication with the thermal control module.

A sports field marking assembly and method of marking creates a boundary reference point and field lines on a field or for coaching. The assembly provides a marker anchoring device that is loaded with field markers. The marker anchoring device comprises a translatable handle coupled to a spring-loaded piston that discharge the field markers into the surface of the sports field. Bristles couple to a rear end of the marker body for visibility above the surface of the field. A tape canister couples to the marker anchoring device to dispense a measuring tape. The measuring tape couples to the field markers, serving to delineate the boundaries and lines on the field. Multiple aligners anchor into the sports field to retain the measuring tape in the formed patterns. The aligners have collapsible and moveable guide posts that can be selectively raised to guide the measuring tape though the chosen guide posts.

The present invention relates to the technical field of electric vehicles, and provides an posture vehicle, which comprises a vehicle body, two wheelers pivoted to the vehicle body, pedals installed on the vehicle body, and two driving components installed in the vehicle body and driving the two wheelers to rotate driven by the pedals. The driving components and the wheelers are in the same operating plane. Namely, in a using process, the user treads on the wheelers, thereby eliminating interference of a balance state of the vehicle body to an output signal of the driving components, and enhancing the sensitivity of the driving components for judging the balance signal.

An embodiment of the present disclosure provides a resistance strain sheet, a sensing assembly, a force sensor and a skateboard, wherein the resistance strain sheet includes: a strain sheet body; and a resistance wire, the strain sheet body having an symmetry axis, a plurality of resistance wires being provided, and the plurality of resistance wires being divided into two groups, the two groups of resistance wires are electrically connected to each other and symmetrically arranged on both sides of the symmetry axis, and each of the plurality of resistance wire being arranged at an acute angle with the symmetry axis.

A method for the continuous ranking of a competitor during a race of a slalom skiing type sports discipline includes the following iterative steps: a step of measuring the variation in the lateral angle of the gliding board about a predefined axis, a step of detecting the moment when the angle passes through a predefined value, a step of recording the competitor's run time corresponding to the detected moment, a step of comparing the stored run time with those of the preceding competitors for the corresponding detected moment, and a step of ranking the competitor with respect to the preceding competitors as a function of the run time of each competitor. A ranking system implements the method.

Smart grips for use on ski poles and handlebars are disclosed herein. A smart grip can include a grip body having an opening mateable to a tubular member. A speaker can be disposed in the grip body and a display can be at least partially contained in the grip body. A controller can be disposed in the grip body and includes at least one processor and at least one memory device storing instructions for causing the at least one processor to receive incoming audio data and output said incoming audio data via the speaker. One or more buttons can be positioned on the grip and coupled to the controller. A battery can be disposed in the grip body and coupled to at least the controller.

Presented is an apparatus and system for an artificial turf system. The artificial turf system includes a backing layer having a plurality of fibers extending therefrom. The artificial turf system further includes a plurality of impact sensors located at least partially on, in, and/or beneath the backing layer, wherein the plurality of impact sensors are operable to detect a force or pressure applied to the backing layer.
