Video Display Viewing Angle Correction (Flex Creations): U.S. Patent No. 8,854,553

The image a person sees on a flat-screen television or computer monitor is best if that person is sitting directly in front of the screen. Being able to mount a television screen – especially a large, flat-screen TV – so that everyone in the room has an optimal view is either very difficult or just not an option. With 3D and 4D screens, the viewer must be directly in front of the screen to enjoy the dynamic picture quality. Until now, the only option was to mount the TV screen on a bracket that would put it at the optimal angle for viewing. The technology covered by this patent addresses that issue, using software to adjust the angle of the image on the screen to where the viewer or viewers are sitting. And the adjustment is made totally through software, so no hardware modifications need to be made!

The acquisition of U.S. Patent No. 8,854,553 for “Video Display Correction to Provide On-Axis View at an Off-Axis Angle” will enable the acquirer to leapfrog the technology of all of its competitors and offer a next-generation viewing experience! This patent would be a critical IP asset for any television OEM.

Lower Cost Horticultural LED (Modern Woodworks): U.S. Patent No. 8,333,487

The invention covered by this patent is the design and assembly of an LED lamp for plant growth that has significantly reduced manufacturing costs.

This patent would give any LED OEM a critical cost advantage in the marketplace!

Ultra-Miniature Multi-Lens Array 3D Camera (NanoLight): U.S. Patent No. 8,077,245

The revolutionary technology covered by this patent allows a high definition mega-pixel camera to be flattened to about the thickness of a postage stamp. The invention replaces the external lens and collapses the entire apparatus into a sandwich including induction or battery powered circuitry, printed pixel and lens array. Each tiny lens rests over a sensor layer of a number of pixels depending on the limit of the lens. Each of these nano-assemblies becomes a nano-sized camera receiving fuzzy or "noisy" images. However the entire assembly of multiple mini cameras is sharpened through computerized interpolation transformation of each of the images to present the observer with a single high-resolution image. Since each element receives slightly different spatial information from the observed object, it also becomes possible to render 3D imaging and depth information.

This patent will be a critical acquisition, enabling its acquirer to leap-frog all current “nano-camera” technologies. The nano-camera developed from this patent has applications in security and surveillance, medical electronics and diagnostics, endoscopy, cell and smart phones, and medical research to name just a few!

It includes a real-time bright pupil detection tracker that recognizes on-lookers of a predefined object. An optical eyeball tracking apparatus uses six degrees of freedom: three translational and three angular coordinates that can be integrated into any location to gather consumer behavior.

This invention performs object locking and tracking. A single camera and two off-axis light sources are engaged. For more precise object tracking, two separate cameras and a single diode are used. In another embodiment, a third camera may be used to separate the locking and tracking tasks. The light sources may have different light wavelengths and may operate in a sequential mode. The cameras may be sensitive over different spectral ranges and may also differ in terms of field-of-view and resolution. This allows advertisers to make informed decisions and quantify ROI.
