Patent number: 11469928Abstract: A receiver circuit comprising an equalizer and a method of correcting offset in the equalizer. In an example, the equalizer includes a plurality of delay stages for sampling and storing a sequence input samples, and a plurality of coefficient gain stages, each coupled to a corresponding delay stage to apply a gain corresponding to a coefficient value. The outputs of the coefficient gain stages are summed to produce a weighted sum for quantization by a slicer. Offset correction circuitry is provided, including memory storing a look-up table (LUT) for each coefficient gain stage, each storing offset correction values corresponding to the available coefficient values for the coefficient gain stage. Addressing circuitry retrieves the offset correction values for the coefficient values currently selected for each gain stage, and applies an offset correction corresponding to the sum of the retrieved offset correction values.Type: GrantFiled: June 30, 2021Date of Patent: October 11, 2022Assignee: TEXAS INSTRUMENTS INCORPORATEDInventors: Ani Xavier, Jagannathan Venkataraman, Nagalinga Swamy Basayya Aremallapur, Aviral Singhal, Arun Mohan, Rakesh Chikkanayakanahalli Manjunath, Aravind Ganesan, Harshavardhan Adepu

Publication number: 20220265371Abstract: In a system and method for determining guide points or a guide path for display on an endoscopic display, image data corresponding to a surgical treatment site is captured using a camera. Using the image data, the positions of one or more reference points within the surgical environment, are determined. Based on the positions of the reference points, the positions of guide points spaced from the reference point are estimated or determined, in some cases using predetermined offsets. The guide points or guide path is displayed as an overlay of the image data on an image display. In an embodiment using the system for a sleeve gastrectomy procedure, the reference points are input by a user or determined by the system with reference to a bougie that has been positioned within a stomach at the operative site, and the guide path is used as a guide for stapling and resection to form the sleeve.Type: ApplicationFiled: February 23, 2022Publication date: August 25, 2022Applicant: Asensus Surgical US, Inc.Inventors: Kevin Andrew Hufford, Caleb T.
