Abstract: The present disclosure generally relates to techniques and interfaces for generating synthesized speech outputs. For example, a user interface for a text-to-speech service can include ranked and/or categorized phrases, which can be selected to enter as text. A synthesized speech output is then generated to deliver any entered text, for example, using a personalized voice model.

Abstract: A method of operating a ride control system of a machine having an accumulator is provided. The method includes detecting a pressure at the accumulator. The method includes generating a first set of input data associated with a drive system and a brake pedal. The method includes generating a second set of input data associated with a lift cylinder. The method also includes determining a working mode of the ride control system based on the first set of input data and the second set of input data. The working mode of the ride control system includes a normal mode and an exposed mode. The method includes operating a ride control activation solenoid valve, upon determining the pressure at the accumulator to be above a predefined threshold, and the working mode of the ride control system to be the exposed mode.

Abstract: A system can include one or more valve arrangements with a working chamber to receive a working fluid at a first pressure, and a control chamber to receive fluid at a second pressure. A dynamic seal can be disposed on a land of a valve element. The valve arrangement may include a sleeve against which the dynamic seal is slidably engaged. The valve element may include a check stem. A pressure compensating system may be in communication with bores formed in with the valve element. A pressure system to monitor dynamic seal wear may be in communication with the control chamber of the valve arrangement.

Abstract: A system and method for calibrating an electronically actuatable hydraulic valve in a work machine may include at least one supply valve and at least one drain valve to be calibrated and a bypass valve in fluid communication with a pump and a fluid source. The at least one supply valve and the at least one drain valve may be calibrated by opening the at least one supply valve and the at least one drain valve, closing the bypass valve, setting the pump to a desired flow output, determining a first current command for the at least one supply valve corresponding to a first target pressure parameter and determining a second current command for the at least one drain valve corresponding to a second target pressure parameter.

Abstract: A controller monitors groundspeed in an articulated machine and selectively disables an automatic articulation control function when the groundspeed is at or near zero. If there is an indication that an operator may not be aware that the automatic articulation control function is active by comparing when a on switch was activated compared to a machine power cycle or an operator not being present, the automatic articulation control function may be inactivated until the on switch is toggled. If the articulated machine is in neutral and the groundspeed is at or near zero, the automatic articulation control function may disabled. If the groundspeed is at or near zero but the transmission is not in neutral, the machine may simply be stalled to due working conditions and the automatic articulation control function may be maintained.

Abstract: An apparatus and method are provided for operating a motor grader having steerable front wheels and a front and rear frame pivotally connected at an articulation joint. The method includes selecting an automatic articulation mode, and commanding front wheel steering to turn the motor grader, providing a plurality of front wheel steering corrections to an electronic controller, filtering the plurality of front wheel steering corrections using a method for filtering steering corrections based on the constant curve mode, wherein the method generates filtered front wheel steering corrections, and automatically commanding articulation of the front frame relative to the rear frame about the articulation joint in response to the filtered front wheel steering corrections.

Abstract: This disclosure is generally drawn to methods, systems, devices and/or apparatus related to compressing the size of engineering development maps. Specifically, some of the disclosed example methods, systems, devices and/or apparatus relate to compression of an engineering development map (e.g., kinematic map) based on a given fixed size and/or based on a given target error tolerance value using gradient search techniques.
