Patent number: 7880887Abstract: Accurate measurements of the concentration of a sterilant in a sterilization chamber are provided through the use of a light source, a first detector that receives light from the light source that has not passed through the sterilization chamber and a detector that receives light from the light source that has passed through the sterilization chamber. The light contains wavelengths known to be absorbed by the sterilant. A controller receives and processes signals received from the two detectors to cancel changes in the output of the light source and then apply a modified Beer-Lambert law to determine the concentration of the sterilant gas.Type: GrantFiled: August 29, 2008Date of Patent: February 1, 2011Assignee: Phygen, Inc.Inventors: Steven J.

Patent number: 6307588Abstract: A method and apparatus for image processing provides a memory having a plurality of individual parallel buffers constructed from random access memories (RAMs) for storing data related to a group of image pixels. The buffers each store a parallel, identical version of the image data so that an image processor can access data related to a given pixel in the overall data from each buffer simultaneously. An address expander for the buffer rows and buffer columns is used to convert a row and column address of a selected “central” pixel into a plurality of related pixel data addresses offset at predetermined distances from the selected pixel data's address. In this manner, the address expanders enable a group of related pixels, each in a different parallel buffer, to be accessed simultaneously, without requiring the processor to be interconnected with all of the buffers. This substantially reduces the complexity of processor interconnection design, while substantially enhancing processor speed.Type: GrantFiled: December 30, 1997Date of Patent: October 23, 2001Assignee: Cognex CorporationInventors: Steven J. Olson, Robert C. Hinz, Kurt M. Anderson

Patent number: 6157751Abstract: A method and apparatus for accessing image pixel data in a plurality of parallel random access memories (RAMs) includes providing the RAMs so that they are arranged in pairs that each include an even RAM and an odd RAM. Each of the pairs includes an identical copy of the image pixel data stored at identical addresses in each of the RAMs relative to each other. An image processor receives image pixel data from the RAMs over multi-bit data lines. and addresses rows and columns of the pairs so that alternating columns of image pixel data corresponding to alternating pixel columns in an acquired image are stored in an alternating manner in each of an even RAM and an odd RAM. In other words, pixel data of alternating odd pixel columns are stored in succeeding columns in the odd RAM and pixel data of all even pixel columns are stored in succeeding columns in the even RAM.Type: GrantFiled: December 30, 1997Date of Patent: December 5, 2000Assignee: Cognex CorporationInventors: Steven J.

Patent number: 6025854Abstract: The invention provides methods and systems for forming and image from a stream of non-interleaved image date, e.g., a stream of non-contiguous rows of pixels. Such a system includes a memory, in which the image is to be formed (and stored), and a controller, for initiating memory transfers that move rows of pixels from the stream to their (the rows') respective locations in memory. The controller initiates those transfers such that (i) the rows of pixels are transferred to the memory in the order in which they are received from the stream, and (ii) each row of pixels is transferred directly to the location in memory corresponding to that row's respective position in the image.Type: GrantFiled: December 31, 1997Date of Patent: February 15, 2000Assignee: Cognex CorporationInventors: Robert C.

Patent number: 5982395Abstract: A method and apparatus for addressing a parallel image processing memory provides a plurality of random access memories arranged in an array in a set of array rows and array columns. Each of the memories has addresses for storing image pixel data that are arranged identically to each other. Each of the random access memories stores the group of image pixel data at the identical addresses. The entire group of image pixel data is stored in each of the plurality of random access memories. The random access memories can be constructed from a plurality of individual random access memory structures that are joined as a single memory storage unit, or buffer that enables one image pixel data to be addressed in each addressing cycle. An image processor generates address values for accessing the group of image pixel data over a plurality of address lines interconnected with respective of the plurality of buffers. The image processor manipulates the group of image pixel data.Type: GrantFiled: December 31, 1997Date of Patent: November 9, 1999Assignee: Cognex CorporationInventors: Steven J. Olson, Robert C.
