As written in comments, the recently acquired Kodak Image Sensor Solutions has been quietly renamed to Truesense Imaging, Inc. Kodak has first used Truesense name for its W-RGB color filter products almost 3 years ago. I wonder if the new company name meant to emphasize the W-RGB products importance.
Meanwhile, Tessera renamed its imaging and optics division into Digital Optics Corporation. The new entity is responsible for wafer-scale optics (former Shellcase), EDoF (former Eyesquad and Dblur), MEMS AF motors (former Siimpel), micro-optics (the original bearer of Digital Optics Corporation name, acquired by Tessera in 2006) and image enhancement software (former Fotonation). It appears that the division has been renamed and separated into the wholly owned subsidiary in June 2011.
Another part of Tessera dealing with chip packaging is separated and renamed too. Its new name is Invensas. In Nov. 2011 Invensas acquired patent assets of California-based TSV foundry ALLVIA. It does not seem to target image sensor applications though.
