Abstract: The sensor interface IC measures or calibrates a target resistance to be used as a gain resistor for a TIA amplifier in the sensor interface IC. One or more excitation currents are generated in response to different specified excitation voltages that are applied to an external calibration resistor having a specified calibration resistance value. Response voltages are measured across the target resistor, respectively in response to the corresponding different one or more excitation currents. The resistance value of the target resistor is determined using a difference between the measured response voltages, a difference between the specified excitation voltages, and the specified calibration resistance value.

Abstract: The present approach relates to the synchronization of frame acquisition by a camera with an external event or trigger despite the camera lacking external control or synchronization capabilities. For example, inexpensive and/or consumer grade camera typically lack a control interface to explicitly synchronize with an external trigger event or external device. The present approach allows synchronization of such a camera lacking external synchronization capabilities with an external event or device.

Abstract: A work machine is moved along a route over worksite terrain. Route data indicative of the route is recorded and an operating parameter data indicative of at least one operating parameter of the work machine is determined as the machine moves along the route. The operating parameter data is used to generate rolling resistance data indicative of the resistance of the terrain to the movement of the work machine as it moves along the route. Then the rolling resistance data is processed to generate compaction data indicative of the compaction of the terrain along the route.
