SRI International , founded as Stanford Research Institute, is an American nonprofit research institute headquartered in Menlo Park, California. The trustees of Stanford University established SRI in 1946 as a center of innovation to support economic development in the region. The institute formally separated from Stanford University in 1970 and became known as SRI International in 1977. SRI describes its mission as discovery and the application of science and technology for knowledge, commerce, prosperity, and peace. It performs client-sponsored research and development for government agencies, commercial businesses, and private foundations. It also licenses its technologies, forms strategic partnerships, sells products, and creates spin-off companies.SRI's annual revenue in 2013 was approximately $540 million. SRI's headquarters are located near the Stanford University campus. William A. Jeffrey has served as SRI's president and CEO since September 2014.SRI employs about 2,300 people. Sarnoff Corporation, a wholly owned subsidiary of SRI since 1988, was fully integrated into SRI in January 2011.SRI's focus areas include biomedical science, chemistry and materials, computing, Earth and space systems, economic development, education and learning, energy and environmental technology, security and national defense, as well as sensing and devices. SRI has received more than 4,000 patents and patent applications worldwide. Wikipedia.

An active electroadhesive cleaning device or system includes electrode(s) that produce electroadhesive forces from an input voltage to adhere dust or other foreign objects against an interactive surface, from which the foreign objects are removed when the forces are controllably altered. User inputs control the input voltage and/or designate the size of foreign objects to be cleaned. An active power source provides the input voltage, and the interactive surface can be a continuous track across one or more rollers to move the device across a dirty foreign surface. Electrodes can be arranged in an interdigitated pattern having differing pitches that can be actuated selectively to clean foreign objects of different sizes. Sensors can detect the amount of foreign particles adhered to the interactive surface, and reversed polarity pulses can help repel items away from the interactive surface in a timely and controlled manner.

The invention relates to medical devices and, particularly, catheter medical devices. In an aspect is a nerve block catheter system comprising a dual-sheath catheter comprising an inner sheath and an outer sheath, wherein distal ends of the sheaths are connected, the inner sheath defines a fluid delivery lumen, and the outer sheath comprises a tissue lock movable between a collapsed position and an extended position, wherein the tissue lock forms a reversible tissue anchor when in the extended position, and an actuator connected to the proximate end of the catheter and configured to activate the tissue lock by sliding the outer sheath length-wise relative to the inner sheath.

An imaging sensor for low light level color imaging includes an array of pixels. Each pixel has a first pixel portion that has a first photosensitive area and is responsive to light in a panchromatic spectral range and a second pixel portion that has a second photosensitive area and is responsive to light in a sub-band spectral range. The first photosensitive area is greater than the second photosensitive area and the sub-band spectral range is narrower than and contained within the panchromatic spectral range. The first and second pixel portions of each pixel are independently addressable. The imaging sensor is beneficial for applications requiring wide dynamic range, low light sensitivity and color discrimination, and enables improved object discrimination and scene interpretation.

A flexible exosuit includes rigid and flexible elements configured to couple forces to a body of a wearer. Further, the flexible exosuit includes flexible linear actuators and clutched compliance elements to apply and/or modulate forces and/or compliances between segments of the body of the wearer. The flexible exosuit further includes electronic controllers, power sources and sensors. The flexible exosuit can be configured to apply forces to the body of the wearer to enable a variety of applications. In some examples, the flexible exosuit can be configured to augment the physical strength or endurance of the wearer. In some examples, the flexible exosuit can be configured to train the wearer to perform certain physical tasks. In some examples, the flexible exosuit can be configured to record physical activities of the wearer.

Mathematical technologies for recommending content to a user based on a users preferences are disclosed. Embodiments of these technologies can generate a probabilistic representation of a data set, and then adjust the probabilistic representation to reflect a user-specific weighting scheme. The user preference-adjusted representation of the data set can be used to recommend content to the user.
