Prosthesis for replacement of cartilage
A cartilage replacement or repair prosthesis comprises a layer of streamlined elastomer elements, preferably in the form of spheres, supported in a matrix material so that the radially opposed surfaces of the spheres are positioned on opposite surfaces of the layer and make contact with the opposed surfaces of the femur and tibia and the forces exerted between these bones extend through the streamlined elements. The matrix material has a substantially lower resistance to deformation than the spheres to control the position of the spheres relative to one another without significantly restraining their load-responsive deformation under forces exerted between the femur and tibia. The layer, with its elastomeric inserts, is sufficiently thin and flexible to allow it to be rolled for arthroscopic insertion into a knee joint.

Deep Learning for Behavior-Based, Invisible Multi-Factor Authentication
InactiveUS20190044942A1Efficiently authenticatingOvercome obstaclesOther decoding techniquesDigital data authenticationUser deviceInternet privacy
Biometric behavior-based authentication may be enhanced by using convolutional deep neural networks to learn subject-specific features for each subject. The advantage is two-fold. First the need for a domain expert is eliminated, and the search space can be algorithmically explored. Second, the features that allow each subject to be differentiated from other subjects may be used. This allows the algorithm to learn the aspects of each subject that make them unique, rather than taking a set of fixed aspects and learning how those aspects are differentiated across subjects. The combined result is a far more effective authentication in terms of reduction of errors. Behavior-based, invisible multi-factor authentication (BIMFA) mays also automate the responses to authentication second and third factor requests (something you have and something you are). BIMFA leverages continuous, invisible behavioral biometrics on user devices to gain a continuous estimate of the authorization state of the user across multiple devices without requiring any explicit user interaction or input for authentication. As a result, BIMFA can demonstrate that a device is under the control of the authorized user without requiring any direct user interaction.

Light Gas Gun
ActiveUS20160161212A1Optimization rangeIncrease lethalityAmmunition projectilesMissile propulsionEngineeringAcoustic signature
An improved light gas gun launches a projectile in a light gas atmosphere as it travels through a frictionless barrel to achieve high muzzle velocities, decreased acoustic signatures, and increased ranges. The light gas atmosphere is introduced by a purge valve prior to firing or by a muzzle valve that holds a positive light gas pressure on the barrel and breech. The muzzle valve also routes the majority of propellant gases through a suppression canister, reducing the light gas gun's acoustic signature. The frictionless barrel uses light gas propellant routed through gas bearings to keep the projectile centered in the barrel and preclude the projectile from contacting the barrel walls, eliminating barrel wear. The system includes a projectile assembly that stores light gas from the firing and injects it into the boundary layer, reducing drag, increasing range and lethality, and decreasing acoustic signature of the projectile down range.

Device and method for pumping fluids employing the movement of gas bubbles in microscale
InactiveUS20050129529A1Eliminating solid frictionEliminate heat lossTelevision system detailsPiezoelectric/electrostriction/magnetostriction machinesLiquid temperatureLight beam
The present fluid pumping method for micro-fluidic devices uses gas bubbles to move fluid by light beams. The light beams are emitted to the fluid near the gas bubble through an optically transparent cover and correspondingly heat the fluid in the micro channels. The liquid temperature variation changes the surface tension of the gas bubble near the heated fluid side, therefore, a pressure gradient between the end portions of the gas bubble generates accordingly. By moving the light beams, the moved pressure difference will be achieved, which will drive the gas bubbles and pump the fluid. Such a fluid pumping can simplify the structure of a micro-fluidic device and eliminate heat loss because of using a controllable light beam.

A wind cap for buildings serves to anchor a building structure securely to the underlying terrain. The wind cap is a series of base plates which are temporarily and removably placed upon the roof of a structure, with a corresponding series of tiedown straps secured over the plates and attached to ground anchors on opposite sides of the structure. Two of the base plate components may be hinged together along their common edges for placement over the ridge line of the roof. Single plates are placed along the eaves and at intermediate points of the roof span. Each plate includes at least one pair of roller support arms adjustably extending upwardly therefrom, with a roller installed between each arm pair. The rollers eliminate the drag of the tiedown strap passing thereover, thereby eliminating asymmetrical loads on the underlying plates and roof as the straps are tightened.
