  • 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: 7474617
    Abstract: Techniques are described for detecting use of a network access node by multiple users to gain access to a network. Packets are received from a network device in communication with the network access node. The packets are evaluated with reference to a plurality of metrics. Each of the metrics is independently representative of an estimated number of user devices from which the packets originate.

  • Patent number: 6857673
    Abstract: A carrier for sport boards such as surf boards. The carrier is a unitary structure formed from a tubular material having a back section which, at its lower end, transitions into a U-shape cradle and a handle. The sport board is received in the cradle and then may be transported by placing the carrier against the side of the user beneath the arm and grasping the handle retaining the board against the side of the user.

  • Patent number: 6140904
    Abstract: A new type of high temperature thermal disconnect has been developed to protect electrical and mechanical equipment from damage caused by operation at extreme temperatures. These thermal disconnects allow continuous operation at temperatures ranging from 250.degree. C. to 450.degree. C., while rapidly terminating operation at temperatures 50.degree. C. to 150.degree. C. higher than the continuous operating temperature.

  • 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.
