Human/machine interface for a machine vision sensor and method for installing and operating the same
Patent number: 7305114Abstract: This invention overcomes the disadvantages of the prior art by providing a human/machine interface (HMI) for use with machine vision systems (MVSs) that provides the machine vision system processing functionality at the sensor end of the system, and uses a communication interface to exchange control, image and analysis information with a standardized, preferably portable device that can be removed from the MVS during runtime. In an illustrative embodiment, this portable device can be a web-browser equipped computer (handheld, laptop or fixed PC) or a Personal Digital Assistant (PDA). The communication interface on the sensor-end of the system is adapted to communicate over a cable or wireless communication link (for example infrared (IR) or radio frequency (RF)), with a corresponding communication interface in the portable device.Type: GrantFiled: December 26, 2001Date of Patent: December 4, 2007Assignee: Cognex Technology and Investment CorporationInventors: Robert Wolff, William Silver -
Patent number: 7167575Abstract: A two-dimensional (2-D) machine-vision safety-solution involving a method and apparatus for performing high-integrity, high efficiency machine vision. A known structured lighting texture pattern is projected upon a target area. A model image of the pattern on an empty target field is stored during an initial training step. The machine vision safety solution digitally interprets a camera image of the light reflected by the objects in the target area to detect and characterize a pattern in the image. The pattern characterization is then processed to determine if a distortion of the characterization factors is larger than a predetermined threshold, and results in an alarm condition.Type: GrantFiled: April 29, 2000Date of Patent: January 23, 2007Assignee: Cognex CorporationInventors: Sanjay Nichani, Robert Wolff, William Silver, David A.

Patent number: 6684402Abstract: A hub that controls the acquisition of images from a plurality of image sources utilizes image acquisition logic that selectively applies a first set of control signals (e.g., “shutter” signals) to imaging devices, causing them to acquire images. The logic applies a second set of control signals (e.g., “readout” signals) to the devices, causing them to output the images to the hub. Those images are transferred by the hub to a host over an isochronous communications medium.Type: GrantFiled: December 1, 1999Date of Patent: January 27, 2004Assignee: Cognex Technology and Investment CorporationInventor: Robert Wolff

Patent number: 6469734Abstract: A two-dimensional (2-D) machine-vision safety-solution involving a method and apparatus for performing high-integrity, high efficiency machine vision. The machine vision safety solution digitally filters a configurable number of time-sequenced images of a viewed area to create a filtered image. A textured background is used as a static target and viewed under ambient light, or alternatively a texture is observed under IR light. An artificial texture can be created with a particularized pattern. Each new image is then compared to the previously created model and a pixel-oriented difference image is calculated. The difference image is then processed for segmentation features attributable to an intruder object. For segmentation results that exceed a predetermined threshold, an alarm condition is set.Type: GrantFiled: April 29, 2000Date of Patent: October 22, 2002Assignee: Cognex CorporationInventors: Sanjay Nichani, Robert Wolff, William Silver, David A.

Patent number: 5798469Abstract: A sintered structure is formed from a powdered material by the steps of providing a first, green powdered material which can be a ceramic or metallic ceramic material. A second, preformed mold blank material to the green powdered material, wherein the preformed mold blank will not fuse with the first, green powdered material. The mold blank material is different green material having a higher sintering temperature than the first green powdered material. Then the structure is fired at the sintering temperature of the first, green powdered material; and the preformed mold blank material from the fired powdered material is removed. Grooves can be formed by pressing non-sinterable lines into a green sheet prior to firing. A wave guide unit can be formed in the ceramic. A ceramic structure can be formed with fracture markings in the green powdered material.Type: GrantFiled: June 7, 1995Date of Patent: August 25, 1998Assignee: International Business Machines CorporationInventor: Robert Wolff Nufer
