  • MOTION ACTIVATED PARKING GUIDE
    Publication number: 20240161625
    Abstract: A motion activated parking guide for automatically displaying the distance between a stationary obstruction and a vehicle is disclosed. A telemetry module is used to store and track position data from range sensors. The telemetry module uses the stored data to calculate the velocity of the moving object in view. When motion is detected the telemetry module will display distance information in numeric form to the vehicle driver. Input elements are provided to the telemetry module to allow the vehicle driver to configure the numeric display properties. A power pack is provided for electrical components.

  • Mechanical processing of oil sands
    Patent number: 10125320
    Abstract: A method of extracting bitumen from oil sands having a transition temperature at which the oil sands solidify includes forming formable oil sands into pellets and cooling at least a surface of the pellets sufficiently to prevent the pellets from aggregating; cooling the pellets to below the transition temperature; fracturing the pellets to release the bitumen from the oil sands while maintaining the temperature of the pellets below the transition temperature; and separating the bitumen from the oil sands in a separator.
