Publication number: 20220398715Abstract: In a method for enhancing accuracy and efficiency in automated visual inspection of vessels, a vessel containing a sample is oriented such that a line scan camera has a profile view of an edge of a stopper of the vessel. A plurality of images of the edge of the stopper is captured by the first line scan camera while spinning the vessel, where each image of the plurality of images corresponds to a different rotational position of the vessel. A two-dimensional image of the edge of the stopper is generated based on at least the plurality of images, and pixels of the two-dimensional image are processed, by one or more processors executing an inference model that includes a trained neural network, to generate output data indicative of a likelihood that the sample is defective.Type: ApplicationFiled: November 6, 2020Publication date: December 15, 2022Inventors: Neelima Chavali, Thomas C. Pearson, Manuel A. Soto, Jorge Delgado Torres, Roberto C. Alvarado Rentas, Javier O. Tapia, Sandra Rodriguez-Toledo, Eric R. Flores-Acosta, Osvaldo Perez, Brenda A. Torres

Patent number: 4829285Abstract: An alarm for sending out distress information when the user is in an abnormal position or when the user wishes to alert others of a distress condition. The alarm includes an omni-directional tilt switch and a transmitter. When the tilt switch has passed a critical angle, a signal is sent to a delay circuit. The delay circuit waits for a predetermined period of time, such as ten seconds, before enabling a transmitter. The transmitter then sends information over a communication link, signaling others that the user is in need of assistance. The invention further includes an alarm for alerting the user that the predetermined position of the tilt switch has been satisfied and that, after the predetermined delay, the distress information will be transmitted over the communication link unless deactivated by the user.Type: GrantFiled: June 11, 1987Date of Patent: May 9, 1989Assignee: Marc I.
