Abstract: A method and apparatus for sensing levels of insoluble fluids within a storage vessel utilizing an array of main capacitive sensors having differing geometries. The array of main capacitive sensors gives the ability to measure the levels of insoluble liquids in a vessel. Each of the main capacitive sensors include at least one pair of conductive plates capable of submersion in the at least three insoluble fluids, and the geometries of the pair of conductive plates differ and are distinct, such as in distance or in width, in each of the main capacitive sensors. In addition, the apparatus and method may include at least one reference sensor placed intermittently along the height of the vessel to provide input as to the permittivities of the insoluble fluids.

Abstract: A strike indicator that indicates when a fish bites and reduces false positives, comprising a light source, a power source, a printed circuit board, an accelerometer integrated circuit mounted on said printed circuit board, and a microcontroller mounted on said printed circuit board. The strike indicator may be housed in a fishing rod, with the light source illuminating the tip of the rod. The accelerometer detects acceleration of the rod, and the microcontroller utilizes an algorithm to determine whether the acceleration is due to a fish biting or due to other causes. If the acceleration is due to a fish biting, the light source is activated, alerting the user that a fish is biting.
