    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.

  • Patent number: 9354051
    Abstract: A system and method for a rangefinding instrument incorporating pulse and continuous wave signal generating and processing techniques for increased distance measurement accuracy. The use of the former technique effectively solves the ambiguity issues inherent in the latter while allowing for relatively simple circuit implementations. Thus, a potentially more accurate phase-based distance measurement technique can be utilized which is also completely independent of the maximum range to the target.

  • Patent number: 9329117
    Abstract: There is provided a way of enabling the discrimination or identification of the kind of a light-emitting particle corresponding to each pulse form signal in the scanning molecule counting method using the optical measurement by the confocal or multiphoton microscope. In the inventive technique, the position of a light detection region in a sample solution periodically along a predetermined route is moved in measuring the light intensity from the light detection region; and a signal of light from a light-emitting particle is detected individually. Then, an index value indicating a translational diffusional characteristic of one light-emitting particle in a plane perpendicular to the moving direction of the light detection region is determined based upon intensity values of signals of light of the same light-emitting particle for identifying a light-emitting particle.
