摘要： A system and method of calibrating a meter of a product distribution machine, such as an agricultural air seeder is shown. The system uses one or both of optical and mass flow sensors to measure the product flow rate. The sensors are used to measure mass flow rate during a calibration process while the machine is in use. To improve sensor accuracy during the calibration process, the meter speed is changed to change the product flow rate to a rate at which the sensor accuracy is increased.

摘要： A product distribution apparatus, shown in the form of an agricultural air seeder is disclosed having sensors to measure the mass flow through the distribution system, sensors to weigh the tank and the product therein, and sensors to measure the quantity of product in the tank. The sensors are used to measure the change in the quantity of product in the tank during a calibration process where the apparatus is operated over an area and the number of rotations of the meter are recorded. The data is then used to determine a mass flow rate per revolution of the meter. A monitoring method is also disclosed in which an ‘area to empty’ and ‘product needed’ to complete a field or task is displayed to the operator.

摘要： A seed spacing monitoring system is used In an agricultural seeder for planting seeds. The agricultural seeder has a furrow opener, a seed meter for metering seed to be dispensed in the furrow, and a furrow closer to cover the seed in the furrow. The seed spacing monitoring system includes a detector supported to detect seeds in the furrow prior to the seeds being covered. The detector provides a plurality of seed presence signals, with each seed presence signal being indicative of a respective seed present in the furrow. A speed sensor is associated with the seeder and provides a speed signal indicating a ground speed of the seeder. An electrical processor receives the plurality of seed presence signals and the speed signal. The electrical processor determines a seed spacing, dependent upon the seed presence signals and the speed signal.

摘要： An impact sensor is located in a distribution tower which divides the seed and/or nutrient flow into individual rows, and a second sensor provides a compensation signal dependent upon one or more variables such as the velocity of the air in the conveying system, implement vibrations. As the seed/fertilizer bounces off of the impact sensor and flows into the individual row air streams, the impact sensor provides a force signal to a processor which calculates the total particulate mass flow rate from the force signal and the air velocity signal. To determine individual seed and fertilizer rates, a rate controller temporarily changes the metering rate of one of the materials, and the processor then calculates the desired information from the mass flow change and meter speed change. Another embodiment includes seed sensor structure at the meter output for achieving or confirming accuracy.

摘要： Sensor systems and methods are disclosed herein, including a sensor chip, upon which at least two surface acoustic wave (SAW) sensing elements are centrally located on a first side (e.g., front side) of the sensor chip. The SAW sensing elements occupy a common area on the first side of the sensor chip. An etched diaphragm is located centrally on the second side (i.e., back side) of the sensor chip opposite the first side in association with the two SAW sensing elements in order to concentrate the mechanical strain of the sensor system or sensor device in the etched diagram, thereby providing high strength, high sensitivity and ease of manufacturing thereof.

摘要： Disposable pressure sensor methods and systems are disclosed. A substrate can be provided, along with a capacitor and an inductor fixed to the substrate to form a pressure sensor thereof. In a variable L configuration, the inductor can be configured to comprise an inductor surface and a diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the inductor surface, thereby resulting in an increase in the inductance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. In a variable C configuration, the capacitor can be configured to comprise one electrode on the surface and one on the diaphragm, such that when the diaphragm is exposed to a pressure, the diaphragm moves close to the capacitor surface, thereby resulting in an increase in the capacitance and a decrease in the resonant frequency associated with the capacitor and the inductor and any associated circuitry. Such increase and/or decrease data are detectable by external interrogation.

摘要： A row crop unit for use in an agricultural seeder includes a furrow opener for opening a furrow in the soil, a seed metering system for metering seed to be placed in the furrow, and a seed placement system for placing seeds in the furrow. The seed placement system and the seed metering system are in communication with each other and at least in part define a seed travel path associated with the furrow. A furrow closer covers the seed in the furrow with soil. A seed temperature conditioner is associated with the seed travel path for varying a temperature of seed traveling through the seed travel path. A temperature sensitive sensor is positioned to sense seed which has been deposited in the furrow between the furrow opener and the furrow closer. An optional packaging tube holds a temperature sensor or sensor array. A lens is mounted with the same tube. A larger diameter tube may be positioned around the sensor packaging tube. A positive air pressure/air flow may be introduced between the two tubes. This positive air-flow forms a positive pressure and/or air flow barrier to push dust away from the sensor lens or sensor surface.
