  • Patent number: 10024459
    Abstract: Methods, apparatus, and systems providing enhanced feed rate control of tubing and conduit feeds by a powered feeder to an in-ground placement device moved across the ground by a steerable vehicle. In one aspect, ground speed of the vehicle is sensed. Feed motor speed is correlated to length of tubing or conduit estimated to be fed per feed wheel revolution by the feed motor. A controller adjusts feed motor speed to match ground speed to feed rate. In another aspect, instead of estimating feed rate by feed wheel rotation, actual speed of movement of the tubing or conduit is sensed. Feed motor speed is automatically and dynamically adjusted to match ground speed to tubing or conduit speed. In either embodiment, sensing of ground speed can be used to sense starting and stopping of the vehicle. This can be used to turn the feed motor on or off. In either embodiment, integration with a precision agriculture intelligent controller can allow operator control right from the precision ag display.

  • Publication number: 20100046792
    Abstract: Methods for relatively high throughput counting of elongated strands including silks of a plant. One method includes segregating similar sized pieces of silks from a section of the plant's silk brush and quantitatively counting the pieces using an automated method. The automated method can be a digital image of the pieces distributed across or above a surface, and image analysis to derive a count of individual pieces. An alternative automated method is to move the pieces sequentially and substantially singulated past a detector.

    Abstract: Apparatus and systems for relatively high throughput counting of elongated strands including silks of a plant are disclosed. One apparatus or system includes segregating similar sized pieces of silks from a section of the plant's silk brush using a tool adapted to obtain uniform samples and system quantitatively counting the pieces by automation. The automated system can be a digital image of the pieces distributed across or above a surface, and image analysis to derive a count of individual pieces. An alternative automated system moves the pieces sequentially and substantially singulated past a detector.

  • Patent number: 5909180
    Abstract: For use within an electrical distribution to control current paths through a plurality of associated circuit breakers, a circuit arrangement comprises a plurality of circuit breakers, each having a status related to open contact position and a closed contact position. An informational display is included within the load-center to display the plurality of statuses at a user access side of the display, and a control circuit, coupled to the circuit breakers and the informational display, automatically monitors the contact status of the circuit breakers and drives the informational display so that a display of the statuses is provided.

  • Patent number: 5524083
    Abstract: A modular circuit interrupter is arranged for interrupting current in a three-phase circuit path providing current from a three-phase source to a three-phase motor. The interrupter includes a contactor unit arranged to interrupt the circuit path in response to a trip command; a current inducer circuit for providing a current signal having a magnitude corresponding to the current in the circuit path; a fault detection circuit responsive to the current signal, for detecting and communicating power faults in the circuit path; and start and stop motor modules. Respective housings are provided for each of the contactor unit, the fault detection circuit, the start motor module and the stop motor module. A data/power communication bus provides a data communication link between each of the contactor unit, the fault detection circuit, the start motor module and the stop motor module.

  • Patent number: 5247454
    Abstract: A circuit monitoring system for a distributed power network employs waveform capturing techniques for efficient and highly accurate monitoring. The system includes a plurality of circuit monitors and a control station, which is coupled to each of the circuit monitors via a multi-drop communications link. Each of the circuit monitors is disposed adjacent an associated one of the branches in the network for sensing power parameters in the branches and for generating and transmitting data representing the power parameters to the control station The control station is used for generating monitoring commands to each of the circuit monitors to provide the system with full system control and evaluation capability. Each of the circuit monitors also includes EEPROM memory for storing and retaining operational data, sent from the control station, in the absence of power. This allows a microcomputer in the circuit monitor to read the retained data for analyzing the sensed power parameter.

  • Patent number: 5233511
    Abstract: In a panelboard for controlling current paths through a plurality of associated circuit breakers, a panelboard enclosure includes circuit breakers which each have a side facing a front side of the enclosure and including a multi-sectioned user interface circuit, that is configured to communicate with at least one of the circuit breakers. The interface circuit includes a first circuit section and a second circuit section. The first circuit section is located adjacent the back wall of the enclosure and behind the second circuit section, and the second circuit section includes communication means for allowing an operator at the front of the enclosure to communicate with the circuit breakers. This arrangement minimizes heat in the back of the enclosure, provides control and monitoring functions at the front of the enclosure and allows room for additional circuitry in the back of the enclosure.

  • Patent number: 5166887
    Abstract: A circuit breaker system employs a sensor circuit to measure the current flow in a conductor. A microcomputer monitors the current flow and trips a circuit breaker if the measured current flow exhibits certain predetermined characteristics. A power supply circuit generates a regulated output voltage proportional to the measured current flow to supply power to a portion of the circuit breaker system electronics. To protect the portion of the electronics powered by the power supply circuit, the output from the power supply is shorted through a resistance circuit for a predetermined period of time if the magnitude of the measured current flow induces an output voltage in excess of a predetermined level.

  • Patent number: 4706155
    Abstract: An electrical distribution system having a plurality of dissimilar protective circuit breakers spaced upstream and downstream along the stream of the system includes a restraint signal interface circuit producing upstream restraint signals to the upstream breakers in response to received downstream restraint signals indicating the state of the downstream circuit breakers. The interface circuit pairs the downstream and upstream restraint signals to have the same electrical parameters and information, ground fault and short-time, content, while different pairs have different parameters and information content. A selection or logic circuit internal of the interface circuit distributes an active information state to all upstream restraint signals carrrying the same information as any one downstream restraint signal in an active information state.
