    Abstract: An optical seed counting system for counting seeds that are dispensed through a plurality of seed tubes associated with a multiple row seed planter. Each seed tube includes an optical sensor having an emitter and a receiver. The emitter and the receiver each include lens components for shaping an optical beam. Optical fibers connect the emitter to an optical beam generating device and the receiver to an optical beam detecting device both positioned remotely from the seed tubes. The optical components of the emitter generate a substantially spatially uniform optical beam across a sensing area within the seed tubes. The detecting device generates a pulse signal where the period of the pulses represents the intensity of the optical beam in the sensing area. Seeds that are dispensed in the seed tubes interfere with the optical beam in a manner that affects the light intensity of the beam. Therefore, the change in intensity of the beam indicates the number of seeds.

    Abstract: An automatic feedback control system for use with an off-road vehicle having an adjustable-elevation, ground-engaging implement, such as an agricultural tractor with a three-point hitch and a plough or cultivator, is disclosed. The automatic control system provides an engine-sensing draft control system which adjusts the height or elevation of the ground-engaging implement so as to maintain the draft or load forces experienced by the vehicle at a substantially constant level. The determination of the draft being produced by the ground-engaging implement is determined by the engine speed deviation from a target point speed which is indicated by an operator-set desired no-load engine speed and an operator-set engine lug-down value or load. To provide proper operation of the engine-sensing draft control system, multiple feedback compensation mechanisms are provided, including a throttle compensation function, an electrohydraulic valve compensation function, a slip-sensing function, a sensitivity (deadband) adjustment, a maximum implement-lowering rate function, and an automatic downshift signal function to cause the transmission of the tractor to downshift to a lower speed to avoid engine stall under certain conditions.

    Abstract: The present invention presents a flight training and synthetic visualization system, which comprises a fully mobile, self-contained data recording unit including a desktop graphics software engine for creating a virtual model of the flight capable of playing back the recorded trip, synchronized with a real-time video or imagery recording of the actual flight with a view from the cockpit of the aircraft as a pilot would actually view the flight, along with ambient audio of the cockpit. This allows for the user of the simulation to view both modeled data of the flight, as well as actual time-sequenced still images or video of the flight. The two sources of data are synched in time so that real video images of the aircraft as it is flying at a specific point in time is displayed in the simulation at the same moment as the rendered visualization of the flight.

    Abstract: An optical particle flow monitoring system for monitoring particle flow through the primary and/or secondary tubes of an air dispensing system, such as an air seeder. The primary tubes include a particle sensor having at least one emitter lens body, which forms a substantially uniform, collimated beam which illuminates a sensing area in a seed tube in order to accurately monitor the number of particles flowing in the seed tube. In the preferred embodiment, optical fibers connect the emitter lens bodies to optical beam generating devices, and connect respective receiver lens bodies to optical beam detecting devices, with both the optical beam generating devices and the optical beam detecting devices being located remotely from the seed tubes for improved immunity to static electricity discharge. All the particles flowing in the secondary seed tubes associated with a given primary tube may be counted by a particle sensor located on the primary tube, thus greatly decreasing the number of sensors and the amount of data processing required to determine the total number of particles dispensed by the secondary tubes of the air dispensing system.
