  • Publication number: 20240052605
    Abstract: An improved controlling of a dumping of a load of an earth moving machine, which has a conveying container configured for carrying the load. Control data for maneuvering the conveying container according to a selected dumping mode are generated by analyzing perception data and/or machine sensing data to determine a material parameter providing information on an adhesive property of a current load of the conveying container. Based on the material parameter, an appropriate dumping mode is selected, e.g. to improve efficiency of the unloading sequence and to reduce wear of the earth moving machine.

  • Patent number: 8666612
    Abstract: Earth moving equipment and other heavy machinery for environmentally harsh conditions are controlled by a control panel supplied with a lock, and such panels are frequently removable to prevent theft or unauthorized operation. The interface is in the form of a plug-and-socket, the parts of which have to be sealed against dust and humidity when not interfacing. In order to prevent wear and to assure reliable control, according to the invention, no part of the connection between the control panel and a receptable is galvanic, the power supply for the control panel is wireless, such as inductive or optical, while communications may occur by means of a two-way radio protocol or by optical means.
