    Abstract: A method for operating a sensor system includes detecting a first wake trigger by a plurality of sensors for a component disposed in a remote location, generating, by each sensor, sensor service data that includes a battery charge level of the sensor, determining an active sensor according to the sensor service data of each sensor of the plurality of sensors, and assigning the active sensor to enter an active mode assigning each sensor of the plurality of sensors, other than the active sensor, to enter a sleep mode, generating, by the active sensor, sensor reading data for the component until an inactive trigger is detected, sending the sensor reading data using a wireless transmission to a sensor data server, and leaving the active mode by the active sensor and entering a sleep mode in response to the active sensor detecting an inactive trigger.

    Abstract: A removable oil filter system includes an oil filter mount, an oil filter element removably connected to the oil filter mount, an impending-bypass indicator connected to the oil filter mount and in fluid communication with an oil in the oil filter system, and a full-bypass indicator in fluid communication with the oil filter mount. The impending-bypass indicator is capable of reporting an impending-bypass condition of the oil filter system. The full-bypass indicator is capable of reporting a full-bypass condition of the oil filter system.

    Abstract: A gearbox filler assembly includes a cylindrical insert attached to an interior of a port disposed within a housing of the gearbox. The cylindrical insert has a first end disposed within the port, a second end extending outward from the port and is configured to receive a detachable filler cap, a retaining lip around at least a portion of a first interior circumference proximate to the first end, and a retaining slot around at least a second interior circumference between the retaining lip and the second end. A retaining ring is detachably coupled within the retaining slot. A cylindrical baffle is detachably retained between the retaining ring and the retaining lip.
