Various embodiments of the invention present techniques for forming structures (e.g. HARMS-type structures) via an electrochemical extrusion (ELEX(TM)) process. Preferred embodiments perform the extrusion processes via depositions through anodeless conformable contact masks that are initially pressed against substrates that are then progressively pulled away or separated as the depositions thicken. A pattern of deposition may vary over the course of deposition by including more complex relative motion between the mask and the substrate elements. Such complex motion may include rotational components or translational motions having components that are not parallel to an axis of separation. More complex structures may be formed by combining the ELEX(TM) process with the selective deposition, blanket deposition, planarization, etching, and multi-layer operations of EFAB(TM).

The present invention is directed to an improved sports helmet including a quick release connector assembly for the faceguard that allows for rapid disconnection of the faceguard from the helmet shell. The connector includes a bracket, and a coupler mechanism featuring an elongated pin, a head component, a spring, a retractable engaging element and a washer. The connector assembly is moveable between a use position wherein the faceguard is secured to the shell by the bracket and the coupler mechanism, and a released position wherein the bracket and the faceguard are disconnected from the shell. An inwardly directed actuation force that lacks a rotational component is applied to the elongated pin to move from the use position to the released position. In addition, the sports helmet includes an adjustable pad assembly comprised of an inflatable bladder and a pad member, wherein the bladder displaces the pad member towards the center of the shell. Once sufficiently displaced, the pad member, which includes a molded pad element, cradles a portion of the helmet wearer's skull.

Methods and devices for processing captured video frames to detect specific changes observable in video using three consecutive video frames. The images in the first video frame are compared with the second frame and the images of the second frame are compared with the third frame to produce two intermediate images which show the first order change observable in video. These interim images are then analyzed. A geometric transformation is found such that when the transformation is applied to one of these intermediate images, the number of pixels which match between the interim is maximized. This geometric transformation, which may include a linear as well as a rotational component, is then applied to one of the intermediate images to result in a transformed image. The transformed image is then subtracted from the other intermediate image to arrive at an end image which shows the second order change or the change in a change observable in video. The second order change image will show only those specific pixels which have changed in the images between the three original video frames. The invention may be used to detect changes in the state of a subject's eyes. A subject's blinking can thus be used for sending binary commands to a computer remotely. In particular, a double blink, i.e., two consecutive blinks, of a person can be used as a hand-free substitute to a clicking of a mouse.

A method of estimating three-dimensional camera position information from a series of two-dimensional images that form a panorama employs common features in adjoining image pairs in the series to estimate a transform between the images in the pairs. The common features are subsequently employed to adjust an estimated rotational component of each transform by reducing error between coordinates corresponding to the common features in three-dimensional space in image pairs, on a pair-by-pair basis. A global optimization of the position estimation, used for long sequences of images such as 360 degree panoramas, refines the estimates of the rotational and focal length components of the transforms by concurrently reducing error between all 3D common feature coordinates for all adjoining pairs.

A system and method for measuring torque on a rotating component, comprising of signal-producing components which are applied to the rotating component, and a means for obtaining the signals produced by said signal producing components, in which at least two signal producing components are applied to the rotating component with some linear separation between the two signal producing components and their corresponding devices for obtaining signals produced, such that torque applied to the rotating component will cause a change in phase between the signals received from each of the signal-producing components and thus permit the measurement of torque based on this change in phase; one embodiment of this invention comprising two magnetic rings, one at either end of a driveshaft, with sensor coils placed near to each magnetic ring such that an alternating electrical current is produced, the comparative phase between these currents permitting measurement of torque on the driveshaft.

Disclosed is a counter-rotating electric motor that includes an outer rotational component, an oppositely rotating inner rotational component, a force output system coupled to the outer rotational component, another force output means coupled to the inner rotational component, and an assembly for reversibly halting one of the rotational components, thereby converting the counter-rotating electric motor into a traditional motor.

The present invention provides a method and system for online health condition monitoring of rotary machinery such as printing presses. The rotary machines have one or more stages and each stage has one or more rotary components. The method comprises the steps of: receiving one or more signals from sensors at each of the rotary units or bearing housings; generating an error matrix and diagnosing rotation synchronization errors among the different stages; generating error matrices using different signal processing techniques and diagnosing the health conditions of rotary components such as gears, bearings and shafts; and identifying the stages and rotary components having imperfections by comparing the current error matrices to stored reference error matrices. The present invention can also be used in other applications involving rotational components such as automobiles, airplanes, and power turbines to name a few.

An improved axial gas bearing for a gas-driven NMR MAS sample rotor is disclosed that utilizes inward flow with a low rotational component over a rotor conical end. A conical flow region is formed between the rotor conical end and a conical stator bearing surface such that the included angle defining the stator surface is not less than the included angle defining the rotor conical end. Gas is injected radially inward with a significant axial rearward component from a number of small holes at high velocity from the periphery into the conical flow region. Compared to the radial velocity components, the tangential flow components of the injected gas are small and preferably opposed to the direction of the rotor rotation. The high and accelerating negative radial velocities may result in significant Bernoulli effect, such that the mean axial pressure over the conical rotor end may be less than atmospheric pressure for a given axial clearance, but as the clearance decreases, the hydrostatic effects exceed the Bernoulli effects and the mean axial pressure over the conical rotor end may then exceed atmospheric pressure by a substantial amount. Thus, a self-stabilizing axial bearing is formed with improved stability and stiffness for rotor surface speeds up to at least 80% of the speed of sound. Motive power required to spin the rotor may be provided by a radial-inflow microturbine at the opposite end of the rotor in a way that is readily compatible with automatic sample change.
