  • Patent number: 11892335
    Abstract: A system for indicating a fluid level in a fluid tank of a machine includes a plurality of lighting units and at least one indicia. The lighting units are sequentially arranged with respect to each other and configured to be sequentially activated or sequentially deactivated to correspondingly indicate a real-time level of a fluid in the fluid tank. The indicia is disposed along the lighting units to correspondingly indicate at least one threshold level of the fluid in the fluid tank. The indicia allows inference of the real-time level to recede below the at least one threshold level if a sequential deactivation of the lighting units moves past the indicia in a first direction. In addition, the indicia allows inference of the real-time level to exceed the at least one threshold level if a sequential activation of the lighting units moves past the indicia in a second direction.

  • Publication number: 20190233007
    Abstract: A method for operating a machine's steering system having an input device, and components to manipulate the machine's traction devices based on the input device's actuation, includes detecting a condition of at least one component of the components in response to an actuation of the input device; determining a steering angle of the traction devices corresponding to the condition of the component according to a map table; receiving an input to set the steering angle to an actual steering angle; estimating a difference between the actual steering angle and the steering angle determined according to the map table; modifying the map table by shifting each steering angle of the plurality of steering angles with respect to each condition of the plurality of conditions based on the difference to generate an adjusted map table; and outputting the actual steering angle based on the adjusted map table to correspond to the condition.
