Publication number: 20240070904Abstract: A method for analyzing an image of a tissue section may include obtaining a plurality of image locations, each corresponding to a different one of a plurality of biological structures; obtaining a plurality of locations of a first biomarker in the image; and calculating a distance transform array for at least a portion of the image that includes the plurality of seed locations. The method may include, for each of the plurality of seed locations and based on information from the first distance transform array, detecting whether the first biomarker is expressed at the seed location, and storing, to a data structure associated with the seed location, an indication of whether expression of the first biomarker at the seed location was detected. The method may include detecting, based on the stored indications, co-localization of at least two phenotypes in at least a portion of the tissue section.Type: ApplicationFiled: October 9, 2023Publication date: February 29, 2024Applicant: VENTANA MEDICAL SYSTEMS, INC.Inventors: Karel J. Zuiderveld, Xingwei Wang, Jim F. Martin, Raghavan Venugopal, Yao Nie, Lei Tang

Patent number: 8543285Abstract: A system and method for accurate express tolling of highway vehicles. A multilane tolling system comprises a tolling (MVIC) unit that collects information from tolling subsystems arranged to take various vehicle measurements. Preferably, an intelligent vehicle identification subsystem sends vehicle information to the MVIC unit many times per second. Preferably, a vision tracking system (VTS) communicates with the MVIC unit and sends the latter information about the vehicle position using vision tracking sensors. Preferably, an RF subsystem conducts multiple reads of a transponder on a passing vehicle and forwards the read information to the MVIC unit. Preferably, a vehicle image capture unit (VICU) captures images of the passing vehicle when a camera in the VICU receives a trigger from the MVIC unit. Preferably, a driver alert module is used alert a driver passing through a tolling point as to account balance associated with a silent toll tag or pay by plate system.Type: GrantFiled: July 11, 2008Date of Patent: September 24, 2013Assignee: United Toll Systems, Inc.Inventors: Jim Allen, Sheng Zhong, Raghavan Venugopal, Tiegang Xie, Fajie Sun, Sangmesh Reddy, Brijesh Rai Chawla, Balaraju Banna, Shyamnath Harinath

Patent number: 8331621Abstract: A toll violation enforcement system that contains a capture unit that receives a trigger signal and takes vehicle images of passing vehicles. A lighting unit configured to operate continuously is provided to establish a major lighting source incident on the vehicle. A processing unit is provided that processes the vehicle image and controls the settings employed by the capture unit. The processing unit preferably contains a plate location module for extracting an original resolution license plate area image from a first vehicle image; an exposure control module for controlling the exposure setting on the capture unit to provide consistent intensity of the license plate area; a resolution reset module for changing the image resolution for a second vehicle image; an image enhancement module for brightening pixels of the second vehicle image; and an image compression module for compressing the license plate area image and second vehicle image to a predetermined format.Type: GrantFiled: May 27, 2005Date of Patent: December 11, 2012Assignee: United Toll Systems, Inc.Inventors: Jim Allen, Sheng Zhong, Raghavan Venugopal, Balaraju Banna, Xidong Zheng
