Patent number: 11964581Abstract: A system, apparatus, and method may operatively couple to an integrated generator that supplies power to a component of a mobile machine that intermittently demands power during operation of the mobile machine and to a charging station. On condition that the component in the mobile machine does not need power, power may be supplied to the charging station. On condition that an electric mobile machine is connected to the charging station, power from the charging station may be supplied to the electric mobile machine. Otherwise, power may be supplied to the charging station in an energy accumulator to store the power.Type: GrantFiled: October 8, 2021Date of Patent: April 23, 2024Assignee: Caterpillar Paving Products Inc.Inventors: Toby A.

Patent number: 11859353Abstract: According to one example, a screed assembly for a paver is disclosed. The screed assembly can include an end gate, a screed extender and a stowage apparatus. The screed extender can be selectively connected to the end gate via a first one or more quick attachment mechanisms. When connected, the screed extender can be configured to operably position the end gate relative to a main screed. The stowage apparatus can have a second one or more quick attachment mechanisms for selectively coupling the stowage apparatus to the end gate. The stowage apparatus can be movable from a first position for transportation of the paver where the end gate is coupled to the stowage apparatus and the end gate is positioned behind the main screed to a second position during operation of the paver where the end gate is decoupled from the stowage apparatus and the stowage apparatus is positioned adjacent the main screed.Type: GrantFiled: May 25, 2021Date of Patent: January 2, 2024Assignee: Caterpillar Paving Products Inc.Inventors: Toby A Frelich, Bee Vang

Publication number: 20230002981Abstract: A paving machine includes a plurality of sensor(s) for generating sensor data associated with a paving operation. Criteria associated with paving mat defects are compared against the sensor data to determine whether the criteria is satisfied and whether paving mat defects are predicted. For example, criteria may include whether a hopper of the paving machine is activated, whether a screed assembly of the paving machine is floating, a speed of the paving machine, and whether heat is applied to the screed assembly.
