An animal watering system including a water tank, interior container and base for connecting to a bowl. A disclosed example includes Bloom filter theory that utilizes a key based upon an indication of the cells involved in the transition and a selected number of hash functions. A radio frequency voltage differential formed between the electrode and the ground produces a radio frequency electric field therebetween which causes a fuel-air mixture to ionize resulting in combustion of the fuel-air mixture. Resolution of a linear array of detector horns is limited by the size of the horns. The combination can be used in the treatment prevention of pathological conditions related in part to an overproduction of free radicals like aging, arteriosclerosis and cancer.
