Abstract
Abstract Method and apparatus for preventing mud slides comprising determining an area of soil to which to apply heat to evaporate water accumulation therein; determining, as a function of water drainage and water accumulation, a desired rate of water evaporation to maintain rigidity of the soil; and applying the determined amount of heat to the soil thereby to prevent mud slides. A series of electrical heating units are deployed strategically in the soil, and are energized by controlled amounts of energy in accordance with the level of a feedback signal from respective sensors located in the respective heating units. Mud slides may be prevented by determining a specific pattern in the area subjected to mud slides in which to deploy a series of heating units so as to form a rigid barrier which holds in place compliant soil in proximity to the rigid barrier.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
A method for preventing mud slides employing a series of heating elements in a predetermined pattern, each said heating element generating and releasing a predetermined quantity of heat energy, said method comprising the steps of: defining a surface area of the earth susceptible to being displaced upon accumulation of moisture; determining, as a function of water drainage, a desired rate of water evaporation for a given water accumulation in said defined area that is necessary to prevent mud sliding therein; determining, as a function of the quantity of heat energy of the heating elements and the desired rate of water evaporation, respective locations of said predetermined pattern in said defined surface area at which each said heating element is to be placed; inserting said heating elements at predetermined depths at said determined locations of said predetermined pattern; and energizing said heating elements with a predetermined amount of energy according to said desired rate of water evaporation whereby to evaporate water accumulation in the aid of preventing mud slides.
Claim 2
Independent Claim
168 words
A method for preventing mud slides employing a series of heating elements in a predetermined pattern, each said heating element generating and releasing a predetermined quantity of heat energy, said method comprising the steps of: defining a surface area of the earth susceptible to being displaced upon accumulation of moisture; determining, as a function of water drainage, a desired rate of water evaporation for a given water accumulation in said defined area that is necessary to prevent mud sliding therein; determining, as a function of the quantity of heat energy of the heating elements and the desired rate of water evaporation, respective locations of said predetermined pattern in said defined surface area at which each said heating element is to be placed; inserting said heating elements at predetermined depths at said determined locations of said predetermined pattern; and energizing said heating elements with a predetermined amount of energy according to said desired rate of water evaporation whereby to evaporate water accumulation in the aid of preventing mud slides.
Claim 3
Dependent Claim
19 words
A method as recited in claim 1, further comprising energizing each said heating element with equal amounts of energy.
Claim 4
Dependent Claim
35 words
A method as recited in claim 1, further comprising the step of defining said predetermined pattern as a grid-like pattern in said defined area so as to reduce the likelihood of a mud slide therein.
Claim 5
Dependent Claim
35 words
A method as recited in claim 1, further comprising the step of defining said predetermined pattern as a barrier at a location in said defined area to reduce the likelihood of a mud slide therein.
Claim 6
Independent Claim
110 words
A method for preventing mud slides employing a series of heating elements in a predetermined pattern, said heating elements adapted to generate and release heat energy, said method comprising the steps of: defining a surface area of land susceptible to being displaced upon accumulation of moisture; determining, as a function of water drainage and accumulation, a desired rate of water evaporation in the defined area which is necessary to attain and maintain rigidity of soil in the defined area; determining a quantity of heat energy required for evaporating said determined amount of water accumulation; and applying said determined quantity of heat energy to the soil in said defined surface area.
Claim 7
Independent Claim
110 words
A method for preventing mud slides employing a series of heating elements in a predetermined pattern, said heating elements adapted to generate and release heat energy, said method comprising the steps of: defining a surface area of land susceptible to being displaced upon accumulation of moisture; determining, as a function of water drainage and accumulation, a desired rate of water evaporation in the defined area which is necessary to attain and maintain rigidity of soil in the defined area; determining a quantity of heat energy required for evaporating said determined amount of water accumulation; and applying said determined quantity of heat energy to the soil in said defined surface area.
