Redaction, Encryption, and Tracking of Faces in Videos (NOA): U.S. Patent No. 10,284,885 and Patent Application

Most police vehicles have dash cams, and many police officers wear body cams. Police regularly use video surveillance to track bad guys. In addition to these police-generated videos, there are all the businesses with security cameras, traffic cameras, home security systems with cameras, and all those smartphone-generated videos. The result is that videos are increasingly being used by the police to investigate crimes and as evidence in criminal proceedings. Authorities often need to – and in many jurisdictions must – release such videos on demand while protecting the personal information in the videos. Manual face redaction is a common methodology to protect the identities of those in the videos, but the storage and distribution of multiple versions of a video (both redacted and unredacted) are complex and prone to leakage of sensitive information.

U.S. Patent No. 10,284,885 addresses exactly that need. The patent was developed with a grant from the National Science Foundation. When a video is archived, the skin tone of the person or persons in the video is automatically encrypted while the video is compressed. This keeps the identity of each individual protected so that a released or leaked version will not reveal the identity or identities of those in the video. When a properly credentialed person accesses the video, an unredacted version – with the original facial features – is produced that is watermarked with a code that matches it to the credentialed person to whom the video was released. Should the unredacted video be leaked, the watermark will reveal who leaked it!

U.S. Patent No. 10,284,885 and divisional U.S. Patent Application 20190218407 for a “Method and apparatus for redacting video for compression and identification of releasing party” would be a critical acquisition for any producer of police video systems or manufacturer of video equipment – especially video editing and storage devices – that is ready to offer a valuable new product to police agencies, governments, and businesses.

Solar Powered LCD Billboard: (Chan): U.S. Patent No. 7,929,065

We’ve come a long way from the roadside billboards with state troopers hiding behind them looking for speeders. Conventional ink-on-paper billboards are being quickly replaced with self-illuminated billboards. Most use LCD illumination, and can be remotely programmed for each new advertiser, and can show a rotating set of advertising messages.

This patent takes the self-illuminated LCD billboard to the next level by adding solar panels and a battery to store the electricity so it is not necessary to run electrical power to the billboard. In fact, a sign of any size can be created from the invention covered by this patent, from small signs directing customers where to go at large events, to signs directing traffic during construction, to signs promoting product promotions, to full-size, roadside billboards.

U.S. Patent No. 7,929,065 for an “LCD hanging brand using solar energy for advertising” comes with Hong Kong Patent Application 1119817. This portfolio gives any manufacturer of LCD-based products the opportunity to launch a new, patent-protected product line with broad applications across many industries.

Dual-Color Day-Night Laser Gun Sight (Gray): U.S. Patent No. 10,436,552

When a police officer pulls out his or her gun, or a soldier goes into battle, there is a haunting fear: Shooting the wrong person or what is known as “friendly fire.” Accuracy for handguns and rifles has been dramatically improved with the addition of laser gun sights. The bullet will impact the target where the dot from the laser appears, dramatically improving not just accuracy, but also reducing response time for the gun user, so laser gun sights are growing in popularity.

But laser gun sights have one ongoing, serious drawback. There are green laser gun sights for daytime use and red laser gun sights for nighttime use. So what does a police officer, for example, on the evening shift do when the first half of his shift is during daylight and the second half is after the sun goes down? The invention covered by this patent addresses that need head on. It creates a single-unit dual-color, red-or-green laser gun sight that can be used day and night. The invention includes an ambient light sensor that can be set to automatically change from a green-to-red or a red-to-green laser as needed based on the lighting. Or the color can be selected by the user.

U.S. Patent No. 10,436,552 for a “Dual color laser gun sight” would be a strategic acquisition for any gun manufacturer or supplier of laser gun sights that is looking for a critical competitive advantage.

Multiple Wavelength Optical Emitter (Valencell): U.S. Patent No. 8,320,982

When multiple wavelengths need to be emitted from an LED (light-emitting diode), LD (laser diode), OLED (organic light-emitting diode), RCLED (resonant cavity light-emitting diode) or EELED (edge-emitting diode), an array of optical emitting devices is needed. There are applications in biomedical endoscopes and biomedical fiber optics where multiple wavelengths need to be emitted, so multiple devices are needed, adding cost and increasing size.

Additionally, as wearable biometric devices become more complex and advanced, there is a greater need for more compact optical emitters that can generate multiple wavelengths in a high density so, for example, multiple biometrics can be assessed using one compact optical emitter embedded in a consumer wearable such as a smartwatch or fitness band.

The invention covered by this patent addresses that need. It enables a highly compact optical emitter to generate multiple, distinct wavelengths, and do so simultaneously! The invention creates multiple wavelengths with a transition layer that includes a plurality of luminescent films. Each film is configured to luminesce at a respective different wavelength range when monochromatic light from the optical emitter passes through it. The luminescent films may be arranged in a face-to-face direct-contact relationship or may be arranged in an array. The luminescent films may include rare-earth doped oxides, phosphors, metal-doped oxides, rare-earth doped nitrides, nanostructures or nanostructured films.

U.S. Patent No. 8,320,982 for a “Multi-wavelength optical devices and methods of using same” would be a critical acquisition for any manufacturer of multi-wavelength LEDs or biomedical endoscopes or fiber optics. The invention can also be used to create a wearable device that warns of toxic or unsafe conditions for workers in mines, chemical plants, refineries, power plants and other harsh environments.

3D Viewing without 3D Goggles (Liechtenstein): U.S. Patent and U.S. Patent Application

One of the major drawbacks and limitations of virtual reality (VR) and augmented reality (AR) are the headsets. The lenses in the headsets make the reality of the image being viewed possible, but VR and AR headsets are heavy and uncomfortable. They cause eye strain and they severely limit viewing time.

This portfolio takes VR and AR to the next level by eliminating the need for stereoscopic viewing aids. It pioneers the concept of gaze-contingent refocusing which will clearly be the new standard in VR and AR. The technology provides the viewer with an enhanced three-dimensional experience without 3D goggles! It enables the user to view plenoptic still images or plenoptic video that incorporates gaze-contingent refocusing that enhances spatial perception and creates embedded markers in the plenoptic video feed that control depth plane settings for each scene.

This portfolio also introduces a novel mode of transitioning between different depth planes, tricking the human eye into perceiving enhanced depth. In fact, the portfolio creates a display device with depth perception that is significantly enhanced compared to anything currently on the market. The portfolio discloses a non-transitory computer-readable medium on which program instructions are stored. When executed by a processor, those instructions enable the processor to determine how long the user's gaze is fixated on each of a plurality of depth planes so that refocusing is contingent on a number of parameters. Using goggles, the VR and AR images are many times more vivid and realistic, especially in terms of depth of field.

U.S. Patent No. 10,218,968 and U.S. Patent Application 20160154460 for a “Gaze initiated interaction technique” would be a strategic acquisition for any supplier of virtual or augmented reality equipment, enabling the acquirer to leapfrog the technology of all of its competitors.

Next-Generation Flat-Panel LED Platform (Byeong-Jun): International Patent Portfolio

LED lighting fixtures are replacing conventional incandescent and fluorescent fixtures in all applications – from residential to commercial to automotive. And to make LED lighting easy to install and replace, they fit into the same sockets as conventional incandescent and fluorescent bulbs. However, flat-panel LEDs do not have socket fasteners, making replacement of them a problem. This portfolio takes LED lighting to the next level by creating an LED platform that is easier to install and maintain.

Using a power supply connector that is connected to the frame of the fixture, the portfolio creates a lighting platform that replaces the current flat-panel LED lighting fixtures with next-generation LED fixtures for which replacing flat-panel LEDs is quicker and easier. The platform re-uses the housing, and that saves money. Also, the lighting fixture produces significantly less glare, and its ingenious design uses less power. This portfolio creates a flat-panel LED lighting platform that is smaller, cheaper, easier-to-install, easier-to-service, produces less glare, and uses less electricity. It is clearly the next generation of residential and commercial LED lighting!

The portfolio consists of U.S. Patent No. 10,139,092 for a “Lighting Assembly” and Chinese Patent Application 201680001411, plus an Australian and Russian Patent. This portfolio would be a strategic acquisition for any LED lighting systems manufacturer. Working prototypes are available upon request for interested parties.

Video Enhancement (HDRLog): U.S. Patent No. 9,607,365 Plus European Patent Application

Not every video is as clear and focused as we had hoped it would be. If you cannot retake the video, what are your options?

This portfolio covers a technology that enhances the quality of still images from an image issued from a burst and videos by feeding the original media into a computing device that does stacking and morphing on each frame against neighboring images to enhance the original image’s quality.

For each neighboring frame, each pixel is moved to correspond to the image media. Once all the neighboring frames are processed, they are stacked in order to increase the signal-to-noise ratio and create a composite HDR image that has no unwanted spots or luminosity fluctuation and is crisper and more vibrant than the original.

U.S. Patent No. 9,607,365 for “Systems and methods for enhancing quality of image media” comes with French Patent 2996034 and European Patent Application 3316213. This portfolio can be used to create image-enhancing software for use by both professional and amateur photographers and videographers, television broadcasters, video production companies, smartphone OEMs, camera and video equipment manufacturers, and video restorers, allowing owners of archive media to meet the latest HDR TV standards.

Re-Focusing Images on the Human Retina (Zhou): Two U.S. Patents and an Open Continuation

One of the challenges facing manufacturers of visual reality and augmented reality goggles is making the computer-generated image as real-world as possible. In the real world, when people see both far and near objects, the focus lens of the human eye changes shape to make objects at different distances appear focused on the retina of the eye. The result is that when you focus on a close-in object, objects in the distance are blurred, and when you focus on an object in the distance, objects in the foreground are blurred. Current virtual reality and augmented reality technologies do not provide a way to adapt close-in and far-away images to the way that people see far and near objects in the real world because the current technology is limited to a display that is set at a fixed distance to the eyes. This limitation is also the reason for dizziness and headaches after prolonged viewing.

The first patent creates an adaptive optical path that is controlled by measuring the focus depth of the viewer's eye, and providing input for an optical path adjustment that simulates a real-world viewing experience. This is done by monitoring shape changes of the eye lens - a natural process as people view images up close and far away - without a feedback loop that would slow down the process. The newer patent includes technology for an optical mirror array that projects an image onto the retina of the eye, creating an optical path adjustment that simulates a real-world viewing experience without the need for the bulky optical lenses used in current-technology headsets. The patent application covers changing the effective optical distance between a display and a viewer's eyes to adjust to the detected focus depth.

Patent or App. No. Title
9,491,431 Method and Apparatus to Produce Re-Focusable Vision by Direct Retinal Projection with Mirror Array
9,699,433 Method and Apparatus to Produce Re-Focusable Vision with Detecting Re-Focusing Event from Human Eye
10,178,367 Method and Apparatus to Realize Virtual Reality

This portfolio would be a strategic acquisition for any virtual reality or augmented reality headset manufacturer or software developer.
