Patent number: 11125146Abstract: Systems and methods are disclosed for determining a temperature of a coolant in a cooling system for an engine and diagnosing a thermostat in the engine responsive to the determined temperature. A system includes a liquid cooling system including a thermostat, the liquid cooling system structured to circulate a coolant, and a controller coupled to the liquid cooling system and the EGR system. The controller is structured to: receive engine heat data indicative of a first amount of heat introduced into an engine; receive heat loss data indicative of an amount of heat loss experienced by the coolant; determine a temperature of the coolant based on the first amount of heat and the amount of heat loss; compare the determined temperature of the coolant to a sensed temperature of the coolant; and determine a status of the thermostat responsive to the comparison.Type: GrantFiled: May 17, 2019Date of Patent: September 21, 2021Assignee: Cummins, Inc.Inventors: Emrah Arslanturk, Jeremy Nethercutt

Patent number: 8644565Abstract: A method segments iris images from eye image data captured from non-cooperative subjects. The method includes receiving a frame of eye image data, and determining whether a pupil exists in the image by detecting glare areas in the image. Upon finding a pupil, subsequent images are processed with reference to the pupil location and a radius is calculated for the pupil. A k means clustering method and principal component analysis are used to locate pupil boundary points, which are fitted to a conic. Using the pupil boundary, an angular derivative is computed for each frame having a pupil and iris boundary points are fitted to a conic to identify an iris region between the iris boundary and the pupil boundary. Noise data are then removed from the iris region to generate an iris segment. A method for evaluating iris frame quality and iris image segmentation quality is also disclosed.Type: GrantFiled: July 22, 2009Date of Patent: February 4, 2014Assignee: Indiana University Research and Technology Corp.Inventors: Eliza Yingzi Du, Zhi Zhou, Emrah Arslanturk
