  • Patent number: 10793166
    Abstract: A method of providing object detection warning to an operator of a machine is provided. The machine includes object detection modules, a display unit and a controller communicably coupled to the object detection modules and the display unit. The method detects at least one object being located within a predefined distance range from the machine and determines a distance and position of the detected at least one object relative to the machine. The method further displays a threat warning widget on the display unit. The widget includes a plurality of threat level indicators, each of the threat level indicators being representative of a warning level as a function of distance and position of the object relative to the machine. Furthermore, the method activates at least one threat level indicator based on the determined distance and position of the detected at least one object relative to the machine.

  • Patent number: 5922094
    Abstract: An apparatus for automatically removing water from a digester system includes a sediment trap attached to a drain system wherein gas, water and sediment enter the sediment trap by way of gas lines, water and sediment are separated from the gas and settle within the sediment trap while the gas is expelled from the sediment trap, and wherein the gas pressure and weight of the water column within the sediment trap are balanced against a water column within a water outlet line to form a water seal to prevent gas from escaping into the atmosphere while simultaneously expelling excess water accumulating in the sediment trap.
