Patent number: 8695396Abstract: 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.Type: GrantFiled: August 12, 2010Date of Patent: April 15, 2014Assignee: Deere & CompanyInventors: Donald K Landphair, James Z. Liu, Lawrence D. Green, James J. Phelan, Samuel Santiago

Patent number: 8504310Abstract: 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.Type: GrantFiled: August 5, 2009Date of Patent: August 6, 2013Assignee: Deere & CompanyInventors: Donald K. Landphair, James J. Phelan, James Z. Liu

Patent number: 5365524Abstract: In accordance with the principles of this invention, Pulse Code Modulation (PCM) signal streams are converted into Asynchronous Transfer Mode (ATM) cells for switching and transmission across a telecommunications network. Each cell carries one PCM sample of up to 48 different voice connections, the voice connections selected from the PCM data streams because they have a common destination. The cells are transmitted over ATM virtual circuits, each circuit transmitting one cell every 125 .mu.s. Advantageously, ATM transmission systems interface with PCM systems without adding appreciable delay and without requiring additional buffering. Advantageously, new voice paths can be established most of the time by using available slots in the cells of existing virtual paths. This application relates to the use of the principles of this invention for implementing a large switching system or a cluster of highly interconnected smaller systems.Type: GrantFiled: November 6, 1992Date of Patent: November 15, 1994Assignee: AT&T Bell LaboratoriesInventors: Thomas L.

Patent number: 5063729Abstract: A cotton path blockage detector has an acoustic output directed toward the discharge door floor on the cotton picking unit directly behind and to one side of the stream of cotton coming off a doffer. When the unit is operating properly, the floor area is generally clear of cotton and a first distance signal is provided. When a blockage occurs, the area begins to fill with cotton and debris, causing a decrease in the monitored distance. A threshold distance signal which is less than the distance signal to the floor causes an alarm to be activated to warn the operator of a plug. To prevent false alarms where the blockage may only be temporary, a slew rate limitation is built into the processing circuit.In another aspect of the invention, the signal radiated into the cotton conveying path is reflected by cotton, and a doppler circuit detects the presence of a doppler shift in frequency indicating moving cotton in the path.Type: GrantFiled: September 19, 1990Date of Patent: November 12, 1991Assignee: Deere & CompanyInventors: Robert E.

Patent number: 5060205Abstract: A distance sensing system includes an ultrasonic transducer, a transceiver and a microcontroller-based signal processing unit. The transducer periodically generates and directs towards the terrain a dual frequency ultrasonic signal. Echo signals from the ground and/or any intervening crop or trash are reflected back to the transducer and are processed. The system generates amplified and filtered echo envelope signals. Leading and trailing edge times are determined as the times the echo signals cross a threshold value which is a certain proportion of a maximum echo amplitude value. A near distance value is derived from the leading edge time of the first echo which exceeds a minimum amplitude. A far distance value is determined as the trailing edge time of the last echo signal which has an amplitude which exceeds a certain value. Multiple echo time and amplitude values are derived from the maximum amplitude echo.Type: GrantFiled: May 29, 1990Date of Patent: October 22, 1991Assignee: Deere & CompanyInventor: James J. Phelan

Patent number: 4991146Abstract: A microprocessor-based ultrasonic intrusion detection system includes an initialization mode wherein a plurality of echoes are cumulatively processed to produce a reference or signature data set representing the area to be monitored without intruding objects. Later received echoes are compared to this signature so that an intruding object will cause generation of an alarm signal. Time varying thresholds are utilized to compensate for attenuation caused by increased distance.Type: GrantFiled: November 30, 1989Date of Patent: February 5, 1991Assignee: Deere & CompanyInventors: Bill J. Ransdell, James J. Phelan

Patent number: 4728954Abstract: A vehicle-mounted ultrasonic velocity sensor includes an ultrasonic transmitter and receiver coupled to transmit and receive horns. In one embodiment, a phase-locked-loop signal processing circuit converts the transmitted and reflected frequencies into a signal indicative of the vehicle velocity. In another embodiment, velocity data is obtained by measuring the period of a certain number of cycles of the reflected signal using a pair of counters, one counting at a rate equal to the reflected frequency, the other counting at a fixed rate. In both embodiments, the variable magnitude reflected signal is applied to an input of a drop-out detection circuit whose output is then connected to an input or inputs of the velocity determining circuits to prevent velocity detection during dropout periods.The velocity sensor may be implemented utilizing radar components.Type: GrantFiled: December 20, 1984Date of Patent: March 1, 1988Assignee: Deere & CompanyInventors: James J. Phelan, Garn F. Penfold, Larry W. Ferguson

Patent number: 4713799Abstract: An ultrasonic horn assembly includes a horn with a bore tapering from a throat out to a mouth. An ultrasonic transducer is mounted in the throat of the horn. A beam narrowing insert includes a headpiece which tapers smoothly from a larger diameter base to a smaller diameter top. A stem projects from the base so that the base and stem define an annular shoulder which faces the transducer. A blind bore in the stem terminates at a flat bottom surface which faces the transducer. A ring receives the transducer and webs project inwardly therefrom to support the headpiece in spaced relationship to the transducer.Type: GrantFiled: September 10, 1986Date of Patent: December 15, 1987Assignee: Deere & CompanyInventors: James J. Phelan, Larry W. Ferguson

Patent number: 4713665Abstract: An ultrasonic ground speed sensor has a vehicle-mounted transmitter and a receiver for receiving signals reflected from the transmitter to the receiver by terrain over which the vehicle travels. An attenuated and phase-shifted transmit frequency is superimposed upon an output of the receiver to cancel cross talk, thus providing a substantially pure reflected frequency. A phase-locked loop converts the reflected frequency to a voltage which represents the direction and speed of the vehicle.Type: GrantFiled: February 2, 1987Date of Patent: December 15, 1987Assignee: Deere & CompanyInventor: James J.
