Publication number: 20220287556Abstract: The present disclosure includes systems and methods for improving images provided by imaging systems by controlling the temperature of these imaging systems without reducing the image quality or increasing noise in the system. In one aspect, a cannula assembly comprises a processor, and a cannula having a distal end configured for insertion into a patient and housing an imaging device, an image sensor, and a temperature sensor. The processor may be housed within one portion of the tube, or it may be located external to the tube or even external to the patient. The processor is operable to receive temperature information from the temperature sensor, determine, based on the temperature information, whether a temperature of the image sensor is within a predetermined temperature range, and maintain the temperature of the image sensor within the predetermined temperature range by modifying an illumination level of the imaging device.Type: ApplicationFiled: October 20, 2020Publication date: September 15, 2022Inventor: Vivek Sikri

Publication number: 20210104177Abstract: A portable surgical training device is provided. The trainer includes a top cover spaced apart from a base to form a simulated body cavity for locating model organs that are substantially obscured from the field of view of the user. The top cover includes a video display, fixed insertion ports and interchangeable inserts containing simulated tissue layers. The training device has open sides for demonstrating and training lateral surgical techniques including a simulated or live tissue colon attached to a support leg for simulating transanal minimally invasive surgery. A training endoscope with an adjustable focal length for use with the trainer and, in particular, with optical trocars is disclosed. The surgical trainer can be angled and is well suited for training laparoscopic surgery techniques and demonstrating surgical instruments.Type: ApplicationFiled: November 23, 2020Publication date: April 8, 2021Inventors: Boun Pravong, Kennii Pravongviengkham, Lee Cohen, Charles C.

Patent number: 8009206Abstract: A system and method adaptively control sensitivity, on a pixel-by-pixel basis, of a digital imager. An illumination intensity level mapping controller determines a number of pixels of image data having illumination intensity levels within a first defined range of illumination intensity levels and determines an illumination intensity level mapping function based upon the determined number of pixels within the first defined range of illumination intensity levels. An exposure controller determines a number of pixels having illumination intensity levels within a second defined range of illumination intensity levels and determines an integration time based upon the determined number of pixels having illumination intensity levels within the second defined range of illumination intensity levels.Type: GrantFiled: January 4, 2002Date of Patent: August 30, 2011Assignee: Melexis Tessenderlo NVInventors: Ichiro Masaki, Lane Gearle Brooks, Vivek A.

Patent number: 7173666Abstract: An area is imaged with a non-standard aspect ratio, e.g. wide aspect ratio, digital imager to produce pixels of image data. At least a portion of the produced pixels of image data corresponding to the captured non-standard aspect ratio image is displayed beginning, for a given frame of pixels of image data, at a column of pixels of image data corresponding to a predetermined column of imaged pixels. The number of columns of display pixels is different than the number of columns of imaged pixels. Motion is detected in the imaged pixels so that a motion responsive portion of the imaged pixels corresponding to the captured non-standard aspect ratio image corresponding to a window of the imaged pixels having motion detected therein can be displayed.Type: GrantFiled: August 22, 2002Date of Patent: February 6, 2007Assignee: SMAL Camera TechnologiesInventors: Ichiro Masaki, Vivek Sikri, Nilesh Agarwalla, Keith Glen Fife
