Patent number: 8628360Abstract: Methods and systems for providing crosstalk compensation in a jack are disclosed. According to one method, the crosstalk compensation is adapted to compensate for undesired crosstalk generated at a capacitive coupling located at a plug inserted within the jack. The method includes positioning a first capacitive coupling a first time delay away from the capacitive coupling of the plug, the first capacitive coupling having a greater magnitude and an opposite polarity as compared to the capacitive coupling of the plug. The method also includes positioning a second capacitive coupling at a second time delay from the first capacitive coupling, the second time delay corresponding to an average time delay that optimizes near end crosstalk. The second capacitive coupling has generally the same overall magnitude but an opposite polarity as compared to the first capacitive coupling, and includes two capacitive elements spaced at different time delays from the first capacitive coupling.Type: GrantFiled: January 22, 2013Date of Patent: January 14, 2014Assignee: ADC GmbHInventors: David Patrick Murray, Bernard Harold Hammond, Jr.

Patent number: 8622302Abstract: This disclosure relates generally to systems and methods for estimating and, at least partially, compensating for fixed pattern noise (FPN) in an image sensor. In one configuration, an estimate of the FPN of an image sensor may be obtained by capturing a dark image (either a linear or an area image, depending on the sensor type) using a first exposure time, an illuminated image may be captured using a second exposure time, the second exposure time is greater than the first exposure time, and the dark image may be subtracted from the illuminated image to compensate, at least partially, for FPN. Certain configurations may utilize virtual scan lines. Two or more dark images may also be utilized to estimate FPN in an image sensor.Type: GrantFiled: March 17, 2010Date of Patent: January 7, 2014Assignee: Datalogic ADC, Inc.Inventor: Bryan L. Olmstead
