Environmental control of an aquarium
First Claim
1. Apparatus for the control of the light cycle, temperature, feed and circulation of an aquarium filled with water said water having a surface, comprising:
- (a) microprocessor means having at least a plurality of control input means and a plurality of control output means;
(b) keyboard means for entering a plurality of functions selectively to each of said plurality of control input means;
(c) means for measuring the temperature of said water coupled to one of said plurality of control input means;
(d) temperature control means positioned so as to change the temperature, said temperature control means having an input coupled to one of said plurality of control output means;
(e) means in said microprocessor for accepting selected temperature data inputted from said keyboard means and comparing said data with said measured temperature and outputting a signal to a control means to control current to said temperature control means until said data and said measured temperature are substantially identical;
(f) timing means coupled to one of said plurality of control input means of said microprocessor means;
(g) light means coupled to one of said plurality of control output means of said microprocessor means, said light means positioned in a manner to illuminate said aquarium filled with water;
(h) means for inputting data from said keyboard means to said microprocessor means in a manner to turn on or turn off said light means in accordance with said inputted data;
(i) dispenser means mounted above the surface of said water, and coupled to a control output of said microprocessor means, said dispenser means timed by input from said keyboard means to said microprocessor means in a manner to selectively dispense onto the surface of said water at predetermined time periods; and
(j) pump means coupled to a control output of said microprocessor means, and means for operating said pump means over a predetermined time period from data inputted from said keyboard means to said microprocessor.

Abstract
Apparatus for controlling the environment of a tank adapted to be filled with water where the tank includes a plurality of control apparatus. The invention specifically utilizes a microprocessor having a plurality of control signal inputs and a plurality of control signal outputs. Apparatus is provided for coupling each of the control signal outputs to each of the plurality of control apparatus. A program device is coupled to the microprocessor signal input such that data can be entered for the control of each of the plurality of control signal outputs and a timing apparatus is likewise coupled to one of the plurality of signal inputs in a manner to allow the microprocessor to calculate the time of day such that data entered by the program device will selectively control the function of each of the control apparatus as necessary to maintain the environment within the limits set by the operator.
