Patent number: 4639878Abstract: A method and system are provided for automatically determining the position and attitude of a three-dimensional body at a work station by utilizing three cameras each of which generates a non-overlapping plane of image data, including a single target point of the body without the use of structured light. The locations of the target points are determined and processed within a programmed computer together with calibration data relating to the expected position of the body in the work station to provide data relating to the position and attitude of the body with respect to the work station. The resultant data relating to the position and attitude of the body are subsequently transformed into a first set of offset data relating to the difference between the actual and expected positions of the body. The first set of offset data is then transformed into a second set of offset data in the coordinate system of a peripheral device such as a robot, programmable controller, numerically controlled machine, etc.Type: GrantFiled: June 4, 1985Date of Patent: January 27, 1987Assignee: GMF Robotics CorporationInventors: Chia P.

Patent number: 4636949Abstract: Method and apparatus for controlling the operation of a commercial deep-fryer cooker as used in preparing fried chicken or other food products. The controller (11), according to the invention, has been designed to control essentially all aspects of the cooking process and includes a number of features which enhance the flexibility of the system, allow it to be operated with greater efficiency and provide increased safeguards against accident or machine malfunction.Among the features provided by the invention is the capability of lengthening or shortening or changing the ending temperature of a cooking cycle without changing the overall cooking cycle. This permits fast changes to be made in a cooking cycle, even while it is in progress.The system also provides protection against a power failure by saving essential data relating to an interrupted cooking cycle so that the cycle can be resumed if the power is restored within a prescribed period of time.Type: GrantFiled: March 7, 1984Date of Patent: January 13, 1987Assignee: AMF IncorporatedInventor: Charles R.

Patent number: 4631683Abstract: A system and method for monitoring vibrations of a machine tool metal-cutting tool insert and interpreting them to promptly detect the initial touch to the workpiece and signal the tool to stop advancing before marring the surface. The signal generated by a sensor such as an accelerometer is preprocessed to eliminate lower frequency machine noise and detect the energy in a higher frequency band, then sampled and analyzed by digital circuitry. In order to avoid false alarms on high amplitude spiky noise pulses generated by traverse operation of the machine tool, the tool touch alarm is delayed longer than the maximum duration of the noise pulses. Two techniques are given to ignore the noise spikes while still detecting the tool touch signal.Type: GrantFiled: August 29, 1984Date of Patent: December 23, 1986Assignee: General Electric CompanyInventors: Charles E.

Patent number: 4620281Abstract: The condition of the cutting tool is monitored during a turning operation and the machine is adjusted to compensate for tool condition. The device is also used as an in-process part inspection system. A probe on the cutting tool-tool holder assembly measures the distance to the freshly cut surface and the probe signal is monitored; when this distance changes indicating tool nose wear, the numerical control is alerted to adjust the tool during the chip-forming operation to compensate for wear. A broken or worn-out tool signal shuts down the machine. After a cutting pass the part is inspected by retracting the cutting tool and running the part program. There is an error in the part when the probe signal and thus the measured distance is not constant.Type: GrantFiled: February 15, 1984Date of Patent: October 28, 1986Assignee: General Electric CompanyInventors: Robert A.

Patent number: 4611269Abstract: An apparatus and a process for detecting an absolute positional value relating to mechanical movement of a member to be measured from a reference point. The apparatus includes a detecting means with a plurality of detectors having periods which are different from one another. Each detector generates an electric signal having a period corresponding to the movement of the member. The signals are stored in a memory. Then, the absolute value of mechanical movement between one of the detectors and the member is specified by using two values. The first value is derived by multiplying the period of the signal corresponding to the one detector by an integer N. The second value is stored in the memory and corresponds to the one detector's partial movement which is less than one period thereof. The value of the integer is decided by using periods and stored values corresponding to other detectors.Type: GrantFiled: November 15, 1983Date of Patent: September 9, 1986Assignee: Toshiba Kikai Kabushiki KaishaInventors: Kimio Suzuki, Jitsuo Toda, Wataru Shimizu
