Said method comprises steps of computing error function for transmission of laser passing through the coating layer, ceasing the deposition process based on the comparison between the error function and a predetermined constant, comparing deposition rates among all laser beams, identifying the area of the coating layer with a different deposition rate, adjusting the multi-mask set to modify the deposition rate on that coating area in the next deposition process, and resuming the deposition process for the next coating layer until uniformity of the coating thickness is reached.

  • Patent number: 10086515
    Abstract: The invention is an in-process calibration system. It is not an open loop system or a closed loop system, but a hybrid system that retains both the low propensity for error of the closed loop system and the simplicity of the open loop system. The invention comprises a housing, one or more robots that move in up to three axes mounted to the housing, at least one sensor for each axis of the robots' movement, and a microcontroller. The sensors are fixed to the housing at known locations, and the microcontroller instructs end effectors of the robots through a sequence of moves that intermittently trigger the sensors. When the sensors are triggered, the microcontroller corrects the idealized location of the end effectors in the microcontroller's calculations to the actual location of the end effectors, which is, at the moment that the sensors are triggered, the known location of the sensors.

  • Patent number: 9854726
    Abstract: An agricultural communication system is provided that enables sensor-to-sensor link communications of peripheral farming devices (planters, fertilizer or pesticide applicators, etc.) so as to enhance diagnostics for locating system faults and blockages. The system also provides a means to operate with single-faults present with real-time diagnostics to the operator. The point-to-point communications also facilitates simplified installation by automatically determining the sensor addressing based on the physical connection of the sensors. Since the sensor-to-sensor daisy chain bus system is self-configuring there is no dependency on the sensor manufacturing data or sequential installation procedure to define the sensor address as required in other prior art systems. A dual power supply from each end of the looped bus with independent switching provides operation in the presence of single-faults, and a diagnostic mode combined with sensor power supply voltage measurements provides fault location.

    Abstract: The output of an avalanche photodiode (APD) comprises a “photocurrent” component comprising photon initiated events resulting from the interaction of photons with the APD and a “dark current” component comprising dark carrier events arising in the APD even when the APD is not exposed to light. Differences in the pulse height distributions of photon initiated events and dark carrier initiated events are used to statistically discriminate between photocurrent and dark current components of APD output.
