Abstract: A multi-directional water sensor comprises a housing having multiple conductive pads on the outer surface of the housing at locations spaced around the periphery of the housing, an electrical power source located inside the housing, a buzzer located inside the housing, and multiple electrical conductors located inside the housing and connecting multiple pairs of the contacts so that electrical current can flow between different pairs of the contacts when they are connected by water. The buzzer produces a sound when electrical current flows between any pair of the contacts.

Abstract: A multi-directional water sensor comprises a housing having multiple conductive pads on the outer surface of the housing at locations spaced around the periphery of the housing, an electrical power source coupled to the conductive pads, and multiple electrical conductors located inside the housing and connecting multiple pairs of the contacts so that electrical current can flow between different pairs of the contacts when they are connected by water. The housing may have a generally rectangular shape, with the contacts located at the corners of the housing. The multiple electrical conductors are connected to an alarm that is energized when electrical current flows between any pair of the contacts.

Abstract: A system for simulating the lighting cycle of the sun obtains a set of inflection points on a solar lighting cycle and also obtains the annual minimum sunlight value for a location at a predetermined latitude; reconstructs the daily and yearly solar cycle based about the set of inflection point and the minimum yearly value; determines the lighting period based upon the daily and yearly cycles; activates a lighting device for the determined lighting period; transmits a series of electrical pulses to the soil and receives a return signal from the soil, the return signal indicative of the conductivity of the soil; determines whether the conductivity indicates whether the soil has an adequate moisture level; and activates an LED to indicate the soil does not have an adequate moisture level.

Abstract: An activation device for supplying an electrical signal to a lamp in response to an outside force comprising a hollow tube, a ball placed within the hollow tube, the ball of a diameter less than the diameter of said hollow tube, a piezo device including a piezo bender coupled to an end of the hollow tube, wherein the outside force produces movement of the ball such that the ball traverses the tube to strike the piezo bender thereby producing an electrical signal; and means for using said electrical signal to activate the lamp.
