An Internet of Thing (IoT) device includes a transceiver coupled to a processor. Blockchain smart contracts can be used with the device to facilitate secure operation.

Implementations describe systems and methods for wireless signaling for electronic scoring for fencing competitions. A method of one embodiment of the disclosure includes establishing, by a signaling device, an electrical connection to a scoring apparatus. A wireless connection is also established to a receiving device. The signaling device receives a first signal from the scoring apparatus indicating that a fencer has touched a weapon to an opponent during a fencing competition. The signaling device transmits a second signal to the receiving device where the receiving device causes a light source of a light source arrangement to be illuminated. The signaling device receives a third signal from the receiving device indicating whether the second signal was received by the receiving device. An isolation unit of the signaling device prevents the third signal from being transmitted to the scoring apparatus.

The invention relates to an accessory for securing points darrt on fencing pes, comprising a screw for securing the point darrt which is located on the tip of a fencing pe, in order to close the circuit of the electric touch-detection device with which said swords are equipped. The invention includes a screw-coupling tool, characterised in that the screw includes a central axially-extending through-hole having a hexagonal or any other prism-shaped configuration, while the actuation end of the tool includes a first cylindrical or frustoconical segment so that it can be easily fitted to the hole in the screw. In addition, a collar is provided half-way along the length or height of the screw, which serves as an end-stop element.

A conductive material of a plurality of separate conductive materials are coupled to a first participant, the conductive material configured to move when the first participant delivers an impact to a second participant. An impedance-based impact sensing mechanism including an impedance changing mechanism that changes impedance as the conductive material is moved towards and away from the impedance changing mechanism as the first participant delivers the impact. An impedance-based impact measuring scoring system determines that the impact occurred based on a change in impedance in the impedance changing mechanism.

A wireless system is disclosed for implementing with traditional fencing equipment and a conventional fencing scoring apparatus for eliminating reel cords in a fencing match. The wireless system utilizes a constant voltage applied to each opponent's sword, and a square wave voltage applied to the lame and other equipment of an opponent, such that voltage changes are utilized to detect contact events. The contact events are recorded in each opponent's transmitter (worn by the opponent) and converted to data for transmitting to a common receiver of the wireless system. The wireless system replaces the reel cord that traditionally connects the body cord of each fencing opponent to a scoring apparatus.
