摘要:
A global navigation satellite sensor system (GNSS) and gyroscope control system for vehicle steering control comprising a GNSS receiver and antennas at a fixed spacing to determine a vehicle position, velocity and at least one of a heading angle, a pitch angle and a roll angle based on carrier phase position differences. The system also includes a control system configured to receive the vehicle position, heading, and at least one of roll and pitch, and configured to generate a steering command to a vehicle steering system. The system includes gyroscopes for determining system attitude change with respect to multiple axes for integrating with GNSS-derived positioning information to determine vehicle position, velocity, rate-of-turn, attitude and other operating characteristics. Relative orientations and attitudes between motive and working components can be determined using optical sensors and cameras. The system can also be used to guide multiple vehicles in relation to each other.
摘要:
A method for containing wind-driven snow, sleet, ice and other particulate to prevent it from drifting on paths of travel and becoming airborne, obscuring visibility, and drifting. Method involves the application of liquid, slurry, foam, gel, powder, or heat to a desired treatment area with a field of snow in a diffuse pattern. The applied treatment prevents the movement of the loose precipitation either by mixing with the precipitation and freezing to form a crust or alternatively by creating a liquid or semi-liquid slush that is not easily displaced by high winds.

The invention relates to making compacted snow pavements and can be used in apparatuses for compacting snow mass. The inventive apparatus for making compacted snow pavements comprises a front sliding support 1, a rear sliding support 2, a power generator 7, a heat unit 5 having a working zone and provided with a means for supplying heat to snow mass through the working zone, and a means 11 for dynamic compaction. The heat unit 5 is made in the form of at least one separate heat module. The means for supplying heat is arranged so as to be capable of adjusting intensity of the heat flow and fixing the direction in which it is supplied to the working zone. The method of making a compacted snow pavement consists in using the inventive apparatus. The technical result attainable thereby resides in providing a pavement that possesses high load-bearing capacity, wear resistance as well as improved gripping characteristics.

Method and apparatus for constructing an ice structure. The disclosed ice structures are a road and a grounded ice island which are constructed on a sheet of naturally-occurring ice in an ocean. A vehicle equipped for driving on ice includes thereon a rotatable grinding wheel which may be urged downwardly against the ice over which the vehicle is driven, thereby generating ice chips which are collected on the vehicle. The chips are mixed with water to form a slurry which is pumped through a hose to a portable sprayer through which the slurry is sprayed, thereby forming the ice structure.

The invention is an apparatus and method of creating and preserving an outdoor frozen surface by covering a defined outdoor ground surface with a layer of white base paper after clearing debris, litter, and other objects from the defined surface which may present a hazardous condition on an ice surface. The layer of white base paper is saturated with water at near freezing or under freezing conditions to allow the water to freeze and hold the white base paper to the defined outdoor ground surface. Thereafter, water is continuously dispensed under freezing conditions to build up a predefined thickness ice layer on the defined outdoor ground surface.
摘要:
An ice composite body has an inner ice core covered by a protective outer armor layer. Thermal insulation is provided between the inner core and the outer armor layer. Refrigeration is accomplished by a system of conduits for refrigerant are located within the body. The insulation and the refrigeration are adapted to maintain the ice core in a frozen condition relative to the ambient temperature. The base of the body cavity can be in direct contact with the water bed such that the ice core is freeze bonded to an advancing ice front in the water bed. The ice composite body provides structures of equal or greater strength than equivalent structures using conventional materials.
