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 liquid delivery device is provided which allows for delivery of precise, small amounts of a target liquid, such as cantharadin, glycolic acid, phenol, trichloroacetic acid, or similar liquids to a specific, discrete target location, such as an area of the skin to treat conditions including, but not limited to: molluscum contagiosum, verrucous vulgaris (warts), verrucous plana (flat warts), acne scars, actinic keratosis, acrochordon (skin tags), seborrheic keratosis, dermatosis papulosa nigra, milia and lentigo (sun spots). The liquid delivery device allows for delivery of the liquid to the target area without delivering the liquid to any part of the area surrounding the precise target location, thereby eliminating unnecessary irritation such as blistering, pain, temporary or permanent tissue damage and/or scarring for the user. The liquid delivery device strongly adheres to the target liquid, eliminating spilling and the resultant danger to the user and eliminating economic waste.
