  • Automobile engine
    Patent number: 11524774
    Abstract: The present invention provides a power device generating greater propelling force and finds that traditional power devices do not include all propelling forces based on the fundamental core propelling force source problem. External pressure is guided to the traditional power devices since the inner speed is higher the outer speed, power consumption for overcoming fluid resistance is high, and mutual contradiction results are obtained.

  • Dynamically adjusting the cutting height of a mower deck based on a mower's location
    Patent number: 11483968
    Abstract: A mower can dynamically adjust the cutting height of a mower deck based on a mower's location. As a mower travels over an area of grass to be cut, a control system can track the current location of each mower deck on the mower. The control system can compare the current location of a mower deck to a boundary of one or more sections defined within the area to thereby determine which section the mower deck is within. When the control system detects that a mower deck has crossed or will cross into a section, it can identify a particular cutting height assigned to the section and dynamically adjust the cutting height of the mower deck to the particular cutting height. When a mower includes more than one mower deck, the control system can be configured to independently adjust the cutting height of each mower deck based on its location.
