摘要: A peripheral perception system for providing a 360-coverage of a peripheral region around a machine is disclosed. The peripheral perception system includes a first perception device mounted to a first surface of the machine, defining a first elevation and a first angle with respect to a vertical axis of the machine; and a second perception device mounted to a second surface of the machine, defining a second elevation and a second angle with respect to the vertical axis. The first perception device scans a first field of view covering a first peripheral region of the machine and the second perception device scans a second field of view covering a second peripheral region of the machine, such that the first field of view and the second field of view combinedly provide 360-degree coverage of the peripheral region around the machine.

摘要: A formulation for stabilizing soils is described comprising bacteria, enzymes and cations, wherein the bacteria preferably correspond to Azotobacter vinelandii and Acidithiobacillus ferrooxidans, the enzyme preferably corresponds to an alginase and the cations are preferably provided in the form of calcium chloride. A method for stabilizing soils; a method for preparing stabilized paths; and use of the soil-stabilizing composition are also described.

摘要: A composition for suppressing dust particles includes from about 51% to about 100% by weight of saturated hydrocarbons, and from about 0 to about 49% by weight of unsaturated hydrocarbons. The composition has a content of wax in the range from about 5% to about 40% by weight of the total composition. A method of making and a method of using such a composition are also provided.

摘要: A grass sports ground is produced by mixing man-made vitreous fibres into soil having relatively high loam levels at a rate in the range 0.5 to 50 parts by weight per 100 parts soil (dry weight), preferably in the presence of moisture to separate the fibres and distribute them among soil particles, and then growing grass. The soil/fibre mixture has desirable moisture management properties as well as good mechanical characteristics providing extended use characteristics even in cold, wet or hot and dry conditions.
