Abstract: A manner of manufacturing a modernized nunchuck using specifically adjusted workings or saw process construction methods, facilitating a better fit and functions for the nunchuck, while increasing levels of safety and precision operations for users. The nunchuck includes a first and second grip handle, having a top and bottom end. The top ends machined with a quarter rounded edge to minimize resistance against movement. A single cord configuration includes a flexible coupling having alike end accommodated and fixed in place by a coupling anchor and anchor support at top end of first and second grip handles. Anchor support also functions as a handle grip guide assisting precise and consistent hand placement during use of the saw nunchuck. Each bottom end comprises an optical stripe, providing a variety of light reflections for improved ocular functions and visual effects enhancing user performance.

Abstract: A pair of hollow tubular members is connected at a first end by a tether. Each distal end of the tether is held in place within each respective end of the tubular member by a sealed ball bearing assembly. Within each tubular member is a cavity suitable to secure a light stick. Each second end of each tubular member has a friction fit cap. Illumination from the light stick emanates through the tubular hollow members or through cut portions thereof.

Abstract: A fight analysis system to objectively determine the quality and quantity of strikes in a fight. In one exemplary embodiment, one fighter wears a receiving module having a plurality of passive RFID tags at different locations that are read by a striking module (e.g., a knife) when the striking module lands on, or comes in proximity to, the receiving module, to provide the location of a strike. Force sensors in the striking module enable determination of the type and force of a landed strike. A graphical user interface module displays information gathered by the fight analysis system.

Abstract: A martial arts demonstration bong is formed of highly polished transparent plastic and provided with end mounted illumination means directed inwardly in line with the bong shaft. The bong is provided with rank indicating colored ring indicators at the ends of a handgrip section in an unstressed section and may be provided with a surface air current whistling device.

Abstract: A nunchaku includes a joint pin for connecting a baton of the nunchaku to a chain. The joint pin includes a front section for extending through a bearing mounted inside the baton to project from an inner end of the baton to connect to the chain, and a circular flange provided at a rear end of the joint pin to abut against an inner side of the bearing. The flange of the joint pin has an outer diameter larger than an inner bore of the bearing and therefore effectively prevents the whole joint pin and accordingly the chain from separating from the baton even when the steel balls of the bearing are badly worn off and fail to engage with the joint pin.

Abstract: The improved jousting apparatus includes two sticks which are joined together with a flexible rope-like connecting member which is anchored within the ends of the respective sticks. The connecting member is long enough to allow motion of the two sticks relative to each other. Each stick includes two positioning rings along the length thereof, the upper ring identifying a normal position for the upper hand of each contestant, the first and second rings together identifying a first disadvantaged position for a selected contestant, and the second ring identifying a further disadvantaged position for the selected contestant.

Abstract: There is disclosed a mixed reality presentation apparatus which generates and displays a three-dimensional virtual image on a see-through display device so as to allow a plurality of players to play a multi-player game in a mixed reality environment. The apparatus has a CCD camera for detecting the mallet positions of the plurality of players, and a sensor for detecting the view point position of each player in the environment of the multi-player game. The apparatus generates a three-dimensional virtual image that represents a game result of the multi-player game that has progressed in accordance with changes in mallet position detected by the CCD camera and is viewed from the view point position of each player detected by the sensor, and outputs the generated image to the corresponding see-through display device. The apparatus determines the motion of each player by detecting infrared rays output from the corresponding mallet on the basis of an image captured by the CCD camera.

Abstract: A subject-matter of the invention is a flexible nunchaku having two striking bodies (3, 3′) connected to an expander (2) which each have an inner body (4, 4′) and in their longitudinal direction one jacket (5, 5′) each made of plastic foam or foamed rubber, with the the inner body (4, 4′) being formed in each case by a highly flexible hose (4, 4′) without any filling of its inside which is inserted into the jacket (5, 5′) and firmly attached. This nunchaku has the advantage of good flexibility with sufficient stability so that choking and blows with physical injury or damage are excluded therewith.

Abstract: A laser pointing nunchaku assembly for providing a visual display of light when using the invention. The laser pointing nunchaku assembly includes a first and second elongated handle portions that each have a first and second end portion. A substantially non-elastic cord has opposite ends. Each of the opposite ends is coupled to an associated first end of the first and second elongated handle portions. Each second end portion of the first and second elongated handle portions includes an opening extending into the second end portion. The invention further comprises a pair of laser pointer assemblies. Each laser pointer assembly is insertable into the opening of an associated one of the second end portions of the first and second elongated handle portions. Each of the pair of laser pointer assemblies is selectively engageable to the associated second end portion such that the laser pointer assembly directs a coherent beam of light outwardly from the associated second end portion.

Abstract: An interchangeable martial arts weapons system is provided comprising (a) a plurality of interchangeable connectable components comprising at least one long tube, at least one short tube, at least one T-handle and at least one illuminative tube, the ends of each of the interchangeable connectable components being provided with a female coupling fitting, (b) a plurality of coupling components comprising at least one and preferably a plurality of coupling studs and/or at least one and preferably a plurality of link connectors, the ends of each of the coupling components being provided with a male coupling fitting configured in such a manner that it is detachably securable to one of the female coupling fittings provided at the ends of the interchangeable connectable components and (c) a plurality of end caps being provided with the male coupling fitting.
