Patent examiners more likely to approve marginal inventions when pressed for time

The less time patent examiners are given to review an application, the more likely they are to grant patent protection to inventions 'on the margin,' says a study co-authored by Melissa Wasserman, the Richard and Anne Stockton Faculty Scholar and Richard W. and Marie L. Corman Scholar at the University of Illinois College of Law.Haste makes waste, as the old saying goes.

Vision-correcting display makes reading glasses so yesterday

The blurred image on the left shows how a person with hyperopia, or farsightedness, would see a computer screen without corrective lenses. The image on the right shows how that same person would perceive the picture using a prototype display that compensates for visual impairments. Images were taken by a DSLR camera set to simulate hyperopic vision.What if computer screens had glasses instead of the people staring at the monitors? That concept is not too far afield from technology being developed by UC Berkeley computer and...

Carnegie Mellon photo editing tool enables object images to be manipulated in 3-D

A 3-D photo editing system developed at Carnegie Mellon University makes it possible to take a photo of an origami crane, left, and turn it to reveal surfaces hidden from the camera, while maintaining a realistic appearance, as seen at right. The object's shape can be changed, here enabling an animation showing the crane flapping its wings.Editors of photos routinely resize objects, or move them up, down or sideways, but Carnegie Mellon University researchers are adding an extra dimension to photo editing by enabling editors to...
