  • Patent number: 4963036
    Abstract: The image pipeline for a vision system includes a series of digital image processing boards controlled by a computer. A video camera generates from a laser beam reflected from the target surface an RS-170 analog video signal which is converted to a digital signal for processing. Bins of digitizing parameters suitable for several target surface reflectivities are stored in computer memory. The appropriate bin is selected from histogram data of pixel intensity levels generated by one of the image processing boards using digitizing parameters from a reference bin. Improved imaging, especially of black surfaces, is achieved by scanning a laser beam to generate a light stripe over a number of image frames using the digitizing parameters from the selected bin and integrating the data from the successive frames using the image processing boards.

  • Patent number: 4862927
    Abstract: A wire harness assembly arrangement acquires, prepares and routes various sections of wire by means of a wiring tool apparatus attached to a robotic manipulator. The tool apparatus moves coincident with an arm of the process controlled robotic manipulator and acquires the wire section through a front end portion. The first end of the wire section is fed into the tool apparatus and through a tail end portion of the tool apparatus. The next portion is wound around a spool member disposed within the tool apparatus and rotatable in response to a controlled motor operation. The front end portion is movable in relation to a wire feeding unit so that the wire section wound around the spool member is wound in a helical manner. The wire harness assembly arrangement can also include a strip/crimp station to prepare the acquired wire section for termination. The process controlled robotic manipulator then routes the acquired wire section along a predetermined path to form a part of the wire harness assembly.

  • Patent number: 4843576
    Abstract: An arrangement for controlling the process temperature in an industrial process involving an extruding operation includes a summing element which sums the difference between the process temperature and a setpoint temperature with the rate of change of the process temperature and conveys this sum to a proportional and integral controller so that the output thereof acts in an inverse manner with the process temperature. This output of the controller is summed with the change of temperature rate which has been fed forward, to generate a demand signal. The demand signal is shaped and compared to a ramp waveform to generate a variable frequencey pulse for controlling a heating and/or cooling device associated with the extruding device. A change of speed rate can also be summed to form the demand signal.

  • Patent number: 4841281
    Abstract: An apparatus for controlling the output of a switching amplifier includes a signal dividing circuit which generates a delayed replica of the carrier signal and a doubled signal having twice the carrier frequency. The doubled signal is effective for establishing a second time delayed signal relative to the first time delayed signal. The first and second time delayed signals are logically operated on so that a three state output representing the carrier signal is attained. A summing amplifier utilizes the two time delayed signals to generate this three state output whereby if the two time delayed signals are out-of-phase, a zero voltage is connected to the drive portion of the switching amplifier thereby limiting the output of the switching amplifier.

  • Patent number: 4787035
    Abstract: The present invention includes an interpreter in which a parser examines a message using grammar and lexical tables to produce a parse table. The parse table is compared to data needed in a semantics table to fire a rule. The firing of a rule causes a function table to be evaluated. The function table includes function calls which can perform user desired functions. Among the functions is a generate function which will take the contents of a table and turn it into a message and route the message to a destination where the destination can be a table, process or device. Plural interpreters can be created where each interpreter includes a workspace containing the above-mentioned tables. Each interpreter can perform a different task such as recognizing the meaning of a message in one language and performing some action such as sending out a message in a different language or updating a database.

  • Patent number: 4763261
    Abstract: A wheel-speed detecting arrangement for detecting the wheel-speed of a vehicle having a fixed wheel-and-axle configuration includes a wheel generator connected to the wheel/axle configuration such that a first distance signal is produced indicating rotational displacement of the wheel. This first distance signal is then synchronized by use of a basic clock and passed onto a first counter which produces a first data signal indicative of the number of distance pulses. A second counter, enabled as a function of the output of the first counter, measures the number of clock pulses occurring within a measuring time period and generates a second data signal representing that time count. The first distance signal also operates a latch circuit such that, upon initial occurrence of any distance pulse, a reading of the second counter is taken and passed through to a calculating circuit.

  • Patent number: 4756494
    Abstract: A vital switch control circuit for a railroad switch machine includes a permanent magnet motor which is immune to stray or induced a.c. currents, and which is operable to either of two directions depending on the polarity of energy applied thereto. Switch-normal and switch-reverse contacts of a switch request relay logic circuit establish alternate positive and negative-current paths which are connected over a minimum number of line wires to a motor control contact arrangement and to a mechanically-interlocked, dual-coil, reversing contactor. The reversing contact is operable only above a specific d.c. voltage, therefore providing low-level d.c. immunity in case of grounding or cross-over conditions arising in the line wires. A reverse motor contact and a normal motor contact are used to alternately establish negative-current paths to the permanent magnet motor.
