An apparatus may determine the quality of a fencing blade. The apparatus may include an electrical current source; a fencing blade to be tested for quality; two electrical cables, each connected between the electrical current source and the fencing blade so as to cause current from the current source to travel through at least a portion of the fencing blade; and a magnetic field sensor in sufficient proximity to the fencing blade so as to enable the magnetic field sensor to detect a magnetic field generated by the fencing blade when the current passes through the fencing blade.

Measuring device / sensor system for measuring, transferring and processing of relevant performance data from training and competition in contact sports, in particular the physical contact and its force effect

In practice and as far as possible, performance data in contact sports, in particular those of factual contact and force effect of relevant objects and persons to each other, are not surveyed separately but evaluated subjectively. In contact sports like martial arts this is especially critical, because an occurred contact and its force effect are the significant success data in these sports. In other types of contact sports, e.g. ball sports one is concentrated on the performance data, that lead to goal achievement (e.g. goal scoring) and is not looking objectively into the performance of participants for, for example, draw conclusions about the correct technique execution at any time in a game or competition. Though there are already measuring devices for some contact sports for detecting force effect and contact, these are limited to several defined single sensors and applications. Therefore it may be possible to make objective measurement but in case of doubt, a subjective evaluation of technique and point assignment is still necessary. This invention contains a system of measuring devices, that can, especially in martial arts sports, improve the point assignment and in other contact sports the evaluation of techniques. These special measuring devices for contact measuring and its movement and acceleration sensors, display systems and hardware interfaces can be combined with software interfaces and be tailored to fit different applications. In case of martial arts sports, the configuration of protective equipment with these measuring devices is one use case, in which the measuring devices detect all relevant data like contact, force effect and movement direction, that can be used for competition decisions.

An Internet of Thing (IoT) sport device includes a body with a processor, a camera and a wireless transceiver coupled to the processor.

A portable fencing track that is readily assembled and disassembled at different venues includes a series of modular panels disposed adjacent to one another and interconnected to form an elongated central fencing floor. A piste or strip of electrically conductive material is placed and positioned with respect to the elongated central floor, and a perimeter floor is arranged so as to surround the central floor and the piste or strip. A threshold, preferably adjoining each of the modular panels located adjacent to the perimeter flooring, has lateral and end sections overlying adjacent portions of the strip and the perimeter floor, and at least one of the threshold sections defines a channel to receive wiring. Support elements are mounted to each of the floor panels and the perimeter floor to resiliency support the floor panels and the perimeter floor on a base surface and minimize damage over time to the ankles or hips of fencers. A process of assembling the track is also discussed.

A Fencing Target Training System that can be used, anytime and anywhere it is properly installed, by a single user, multiple fencers/users, coach(es), and others for as long as desired to practice, train, coach, and conduct recreational fencing with a stand-alone system when other options are not available or as a complimentary system to traditional methods. It is comprised of three major entities: A main wall mounted opponent fencer target henceforth referred to as (40) which can be replaced with other FTTS targes as presented in FIGS. 19 through 37; a supporting wall or ceiling mounted opponent fencer simulated interaction/reaction sword blade contraption henceforth referred to as (42) with and optional add-on target of (98); and a strip (or piste)/foot placement measuring tape henceforth referred to as (44), and as all depicted in FIG. 1. The advantages of the FTTS are an integrated system that provides the individual fencer or multiple users with an interactive and hybrid way to practice/train for speed, accuracy, timing, mental focus, visualization, form/footwork, techniques, tactics, procedures, physical fitness and endurance, or other activities related to the sport of fencing and other recreational uses in a club, home, or other place of sport/recreational usage.
