Appl. No.:

6/065179

International Classification:

H01C 1000

US Classification:

338195

Abstract:

A method of fabricating thin and thick film resistors which results in stable resistance characteristics, ability to withstand high current or voltage and a precise method of trimming small resistors. After the resistor film (20) and contacts (22 and 23) thereto are formed, the resistors are trimmed by a cut (24) along the length dimension so that the width of the current path is reduced uniformly. The waste portion of the resistor is then separated from the circuit by a cut (27) along its width. Current crowding in the vicinity of the cut is therefore essentially eliminated.

Abstract:

A web-based irrigation controller with application server can avoid need for access points for irrigation controller communications to the application server, need for configurations on any number of any type of web-based appliances to communicate to the application server, and can provide easy access to giant databases of weather and plant growing information, automatic control and simplification for the plant and lawn growing effort, easy access to reports of actual water usage and power usage and maintenance problems, using sprinklers in an unusual manner to scare away birds from a freshly seeded lawn, reducing lawn water usage for unskilled users by backing off lawn timings until the user intervenes, slow seasonal adjustment to watering times without need for application server intervention, life-cycle based watering schedules based on types of garden plantings and easy for the user to follow the actions of a local amateur master gardener in growing similar plants.
