LED Fixture Light Guides Solution Overview
Beginning with edge-lit back lighting, Rambus has pioneered light guide-based design solutions for a broad range of LED lighting applications, enabling a new level of styling, efficiency and control of light.
We combined TruEdge™ LED Coupling – techniques to maximize the amount of light emitted from the LED to the light guide – with MicroLens® optics – micro 3D features that provide controlled light extraction – to create highly-efficient and cost-effective solutions with unparalleled design flexibility.
Our offering includes customizable light guide design and manufacturing solutions with expert optical engineering support. The light guides are available as off-the-shelf or customized designs that are optimized to specific customer and application requirements by varying the size, shape and density of the MicroLens optics. These light guides can be manufactured by our global lighting partners or at our state-of-the-art facility within the US.
Complete fixture prototype designs that combine Rambus optical innovations with design engineering and manufacturing support services are also available to lighting system companies and fixture manufacturers worldwide.
Lensless Smart Sensors Solution Overview
Imaging and smart sensors are essential for the Internet of Things to become a reality. In order for the objects and machines around us to adapt and anticipate our changing needs, they must be able to gather and act upon relevant data from their surroundings quickly and cost-effectively.
We have pioneered a new class of computational imagers ideally suited for ubiquitous sensing with our ultra-miniature Lensless Smart Sensors (LSS). LSS take a novel approach to reduce the size, cost and power consumption for sensing and imaging by replacing the lens with a low-cost diffraction grating attached directly to the image sensor array. Each grating has a unique design that creates a predictable and pattern on the sensor that is used to capture data-rich images and information about its surroundings.
The gratings and sensors are combined with computational algorithms optimized for specific applications. The net result is a smart sensor with a smaller form factor, better power efficiency, greater precision, and lower cost compared to a traditional image sensor with computer vision. LSS can be used for a broad range of tasks including point tracking, gesture recognition, change detection, motion flow and range finding.

Binary Pixel Imagers Solution Overview
Our Binary Pixel technology combines a breakthrough imager and processing architecture to enable professional quality images from mobile phones and point-and-shoot consumer cameras. The technology mimics the brilliance of human visual processing by sensing photons using discrete thresholds similar to the rods and cones of the human eye.
This “binary operation” allows the imager to capture the full gamut of details in dark and bright by using discrete thresholds to avoid pixel saturation and enable better light sensitivity. Binary Pixel also uses spatial oversampling which sub-divides Individual pixels to capture more data and extend dynamic range of the imager.
In addition, innovative processing improves low-light capture and enhances stop-motion performance for dramatically sharper images of moving objects. The net result is significantly improved image quality and performance in a form factor ideal for mobile devices.
High Speed Memory Interface Chipsets Let Server Performance Fly
The demands on server performance continue to increase at a tremendous pace. New requirements from large in-memory databases that are powering today’s cloud services and advanced analytics tools are arriving just as the impact of Moore’s Law is starting to slow. This is setting up a classic performance challenge that requires rethinking some of the core elements of today’s server architectures, particularly when it comes to memory. One key new opportunity is for high-speed server memory interface chipsets, which enable high-speed memory performance without compromising on memory capacities. Companies looking to optimize their server memory architecture designs, and improve their overall server performance and reliability, should give serious consideration to optimized DDR4 memory interface chipsets, which enhance the performance of server memory modules.
