Patent number: 5936234Abstract: A seed monitor includes a planter master unit having one or more planter counting units connected to the planter master unit, with each planter counting unit associated with a different seed tube. Each planter counting unit includes a light source, a means for forming a light beam that traverses a sensing area of a seed tube, a detector and a processor. The circuit board connects the detector and light source with a processor. The processor adjusts the intensity of the light source and selects an output amplifier gain that is appropriate for the counting of seeds. In this manner, the planter monitoring system adjusts for long-term dust and dirt accumulation and aging of components. The processor processes the selected stage of amplified output from the detector and determines the number of seeds that have traversed the sensing area of the associated seed tube. The planter master unit receives binary data of the counted seed, and from this data, provides an output to the operator.Type: GrantFiled: May 19, 1997Date of Patent: August 10, 1999Assignee: Deere & CompanyInventors: John C.

Apparatus and method for removably positioning optical fiber to circuit board component in enclosure
Patent number: 5857054Abstract: An apparatus and method for removably attaching one or more optical fibers so as to be in alignment with a respective electro-optic component on a circuit board within an enclosure. In a first embodiment, the header attaches to an aperture of an enclosure, thereby protecting the circuit board from dust and liquids. In a second embodiment, the header and protective enclosure are one integral unit. The invention enables one or more optical fibers to be detachably attached to a first side of a header or header/enclosure, and for a circuit board having one or more electro-optic components precisely positioned thereon to be attached to the other side thereof and accessed by the attached fiber by a through-hole in the header. A ferrule surrounds at least one optical fiber near an end thereof and includes a seating surface which seats on the exterior side of the header or header/enclosure.Type: GrantFiled: April 22, 1997Date of Patent: January 5, 1999Assignee: Phoenix International CorporationInventors: John C. Thomas, John D. Paulson, Jon T. Jacobson -
Patent number: 5847389Abstract: An optical seed flow monitoring system for monitoring seed flow through the primary and secondary seed tubes in an air seeding system. The primary seed tubes include a primary seed sensor having a plurality of emitter lens bodies and receiver lens bodies. Optical fibers connect the emitter lens body to an optical beam generating device and the receiver lens body to an optical beam detecting device both positioned remotely from the seed tubes. Alternately, one or more of the secondary seed tubes can include a secondary seed sensor having an emitter lens body and a receiver lens body.Type: GrantFiled: May 13, 1996Date of Patent: December 8, 1998Assignee: Phoenix International CorporationInventors: Karl-Heinz O.

Patent number: 5834764Abstract: An improvement in a light collecting system for an agricultural seed monitor is disclosed. The light collecting system includes three optical surfaces: a convex lens surface, a planar surface, and a total internal reflection, cone condenser surface. The convex lens surface is designed to collect light from a seed sensing area of a seed tube and form a converging light beam. The converging beam is then incident onto the planar reflecting surface, which folds the optical axis of the converging light. The converging light beam is then incident onto a non-imaging, total internal reflection cone condenser surface. In a preferred embodiment all three optical surfaces are formed on a single prism made of plastic, with the convex lens being a spherical surface having a radius of curvature of about 20 mm, and the cone condenser surface having an input aperture diameter of about 6 mm and an output aperture diameter of about 0.9 mm.Type: GrantFiled: May 19, 1997Date of Patent: November 10, 1998Assignee: Deere & CompanyInventors: Douglas L. Hauck, Carolyn C. Mertins, Christopher J. Skarie, Jon T. Jacobson, Karl-Heinz O. Mertins

Patent number: 5831539Abstract: A particle blockage monitoring system employs a flexible piezoelectric particle sensor element in a portion of a particle flow path so that a number of particles traveling in the particle flow path strike the flexible particle sensor element while preventing damage to the particles and maintaining the forward momentum of all the particles in the particle flow path. In order to provide flexibility in monitoring particles of different types and to increase the information rate, the use of a one-shot multivibrator to temporarily store a particle detection signal as in the prior art is avoided. Also, serial sampling of the particle sensor data is avoided to increase the information rate. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.Type: GrantFiled: October 22, 1997Date of Patent: November 3, 1998Assignee: Deere & CompanyInventors: John C. Thomas, Douglas L. Hauck, Christopher J. Skarie, Jon T. Jacobson, John D. Paulson, Trevor D. Fuss, Daryl N. Roehrich, Jeffrey G. Hopman

Patent number: 5831542Abstract: A seed blockage monitoring system employs a flexible, generally flat piezoelectric seed sensor element inserted at an acute angle of about 13 degrees into a seed flow path so that a portion of seeds traveling in the seed flow path strike the seed sensor element, preventing damage to the seeds and maintaining forward momentum of all seeds in the seed flow path. In order to provide flexibility in monitoring seeds of different types and to increase the data rate that information can be obtained from numerous multiple seed sensor elements, the use of a one-shot to temporarily store a seed detection signal and serial sampling of the temporarily stored signals from the sensors as in the prior art is avoided. Instead, a comparator that includes a diode in a feedback loop so as to function as a latch is used in conjunction with a serial shift register that has parallel data input lines.Type: GrantFiled: June 27, 1997Date of Patent: November 3, 1998Assignee: Deere & CompanyInventors: John C.
