Abstract: A system for regulating an environment within an operator cabin of a machine via a heating, ventilation, and air conditioning (HVAC) system includes a first sensor that generates a first signal of an amount of air pressure within the operator cabin, a second sensor that generates a second signal of an amount of carbon dioxide within the operator cabin, an air filtration element to direct pre-cleaned air into the operator cabin, an inlet valve disposed between the air filtration element and the HVAC system for controlling a flowrate of the pre-cleaned air to the HVAC system, and a controller. The controller actuates dynamic auto-control of the inlet valve to direct an optimally varying flowrate of the pre-cleaned air from the air filtration element to the HVAC system via the inlet valve to maximize a service life of the air filtration element.

Abstract: A controller for a spark plug of an engine is provided. The controller is configured to receive a signal indicative of an operational parameter of the engine. The controller is configured to define a breakdown time duration for the spark plug. Further, the controller is configured to determine an optimum amount of energy required to generate a spark for the spark plug based on the defined breakdown time duration and the operational parameter. The controller is further configured to cause the optimum amount of energy to be supplied to the spark plug to cause the spark to be generated for the spark plug.

Abstract: A system for communicating over a Controller Area Network (CAN) bus may include a central controller and a plurality of smart devices communicatively coupled with the central controller over the CAN bus and over an identification verification network separate from the CAN bus. Each smart device may be configured to at least one of measure various parameters and control a function based on a command received from the central controller, and then communicate one or more signals indicative of at least one of the measured parameters and the function over the CAN bus to the central controller. Each of the smart devices may include a physical input, a physical output, and at least two nonvolatile memory locations.

Abstract: A control system is disclosed for use with an engine. The control system may have a power source and a main control module configured to receive power from the power source and direct control signals to at least one component of the engine. The control system may also have an auxiliary power module that is selectively connectable to the main control module and to the power source. The auxiliary power module may be configured to receive power from the power source and direct control signals through the main control module to the at least one component of the engine.

Abstract: A temperature measurement system is provided to measure temperatures using temperature sensors. The temperature measurement system may include a controller having a plurality of address lines, a sensor configured to provide a plurality of inputs, and a connector configured to accept the inputs from the sensor. The temperature measurement system may also include a first multiplexer coupled with at least one input from the sensor and including a plurality of selector lines, and a second multiplexer coupled with one or more other inputs from the sensor and including a plurality of selector lines. The selector lines of the second multiplexer may be respectively coupled to the address lines of the controller.
