Abstract: A liquid level measurement system may include a liquid level sensor coupled to an outside of the tank, the liquid level sensor configured to output a sensor signal, and a controller configured to receive the sensor signal from the liquid level sensor and determine whether the liquid within the tank is at a level at or above the liquid level sensor based on the sensor signal.

Abstract: A back up system for ride-on equipment includes a plurality of back up sensors configured to sense an object within a back up region of the ride-on equipment, a deterrence device configured to emit a sound, a display configured to display the sensed object, and a controller configured to: determine whether the sensed object is within the back up region based on feedback from the plurality of back up sensors, and activate, in response to determining that the object is within the back up region, the deterrence device and the display.

Abstract: A multi-port charger includes two or more integrated power delivery modules electrically coupled to an AC-to-DC power converter. Each of the integrated power delivery modules includes a module controller in signal communication with a digital communication bus, a USB-PD controller, a switch-mode DC-to-DC power converter which is configured to provide an adjustable output voltage to a sink device via a USB voltage bus, a first analog-to-digital converter (ADC) circuit in signal communication with the USB-PD controller and the USB voltage bus to generate a digital representation of the output voltage, and a second ADC circuit in signal communication with the USB-PD controller and the USB voltage bus to provide a digital representation of an output current provided by the switch-mode DC-to-DC power converter to the sink device.

Abstract: A noise suppression system for an electric generator having a housing including an internal combustion engine and air-cooled alternator. A fan draws ambient cooling air into the housing for cooling the alternator. The system may include an acoustically designed noise suppression shroud forming a cavity which contains a plurality of parallel flow baffles. The baffles define air flow passages there-between which receive cooling air heated by the alternator. In one system, the baffles are configured and arranged to block a straight line of sight between the entrance and exit of each passage. The baffles may each further include sound deadening materials on one or both sides in some configurations. Heated cooling air flows into the shroud and through the passages before being discharged from the housing. The shroud is operable to suppress noise produced by the cooling air discharge flow. Various shroud configurations may include additional sound proofing features.
