Described herein are guidewire positioning and support devices, method for using them, method of treating a subject using them, and systems including such guidewire positioning and support devices. These devices typically include a rotatable distal tip region that may include one or more wedges. The wedges may be extendable from the rotatable distal tip. The distal end of the device may be steerable, and may be steered while still rotating the distal end of the device. The wedges (which may include sharp forward-cutting blades and blunt lateral portions) can be extended from the distal housing and locked in any position (extended, partially extended or retracted) and rotated clockwise and/or counterclockwise while locked in a retracted, extended or partially extended position. The distal region of the device may also be controllable steered from the proximal end of the device. Systems including these guidewire support catheters are also described, as are method of using them, including methods of treating chronic total occlusions.

A damper pin is disposed between adjacent buckets of a turbine rotor. A first bucket has circumferentially extending supports defining a pair of axially spaced surfaces on which a damper pin rests in a cold condition of the turbine. The adjacent bucket is undercut adjacent its platform to provide an angled surface overlying a generally correspondingly angled surface of the damper pin. The damper pin fits slightly loose within the recess and, upon turbine rotation at speed, the angled surfaces of the damper pin and recess cooperate to bias the damper pin against the first bucket whereby the damper pin engages both buckets and dissipates vibratory action.

A lower extremity orthosis is configured to be coupled to across at least one joint of a person for gait assistance and can incorporate knee, thigh, hip and ankle/foot assistive orthotic devices which can be used in various combinations to aid in the rehabilitation and restoration of muscular function in patients with impaired muscular function or control.

Identifying live eggs includes: a) illuminating eggs with light; b) receiving light passing through each egg at a light detector; c) generating an output signal that corresponds to light received at a light detector for each respective egg; d) analyzing the output signals to identify an indication of an external disturbance; e) analyzing the output signal for each egg to identify the existence of an embryo heart rate and/or embryo movement; and f) designating an egg as a live egg in response to identifying embryo heart rate and/or embryo movement. Steps a) through d) are repeated if output signals from a predetermined number of eggs contain an indication of an external disturbance to the eggs. Steps a) through f) are repeated if the number of eggs designated as live exceeds an expected number, or if embryo movement occurs at about the same time in a predetermined number of eggs.

A sheet restrainer is used to restrain movement of continuously traveling glass sheet and includes arms on either side of the glass sheet. A driving device coupled to the arms moves the arms from a retracted position in which the arms are withdrawn from the glass sheet to an engaged position in which the arms are near the glass sheet and in alignment with each other. Rollers are connected to the arms and contact the glass sheet in the engaged position. A damping device applies an adjustable damping force to at least one of the arms dampening movement of the arm in the engaged position thereby restraining movement of the sheet. In a method of operation, the damping devices restrain angular and/or lateral movement of the sheet by transmitting movement of the sheet against the rollers into a resistive damping force of the damping devices.

Tunable filters can use Fano metasurface designs having extremely narrow transmission bands. The Fano metasurface can comprise dielectric or semiconductor materials and can produce transmission bands with quality factors well in excess of 1000—at least a factor of 50 greater than typical metamaterial-based infrared resonances. Numerical simulations of these metasurfaces show that the spectral position of the passband can be changed by slightly changing the position of a small dielectric perturbation block placed within the near-field of the resonator by using simple electromechanical actuation architectures that allow for such motion. An array of independently tunable narrowband infrared filters can thereby be fabricated that only requires deep-subwavelength motions of perturbing objects in the resonator's near-field.

An imaging means mounted on a vehicle performs imaging resulting in grayscale images having brightness values corresponding to object temperature, and objects around the vehicle are detected from said images. On the basis of said grayscale images, display images to be displayed on a display device mounted on the vehicle are generated and displayed on the display device. The display images are generated by lowering the brightness of areas not corresponding to the objects detected in the grayscale images. The display device is positioned in the vehicle width direction at no more than a prescribed distance away from an imaginary line passing through the center of rotation of the vehicle steering wheel and extending in the longitudinal direction of the vehicle. Accordingly, because display images are generated in which only the objects are spotlighted, the driver can quickly comprehend the objects present when using a display device.

A method for filling and closing pharmaceutical objects disposed in parallel rows in nests includes removing the objects from the nests at an inlet of a conveying device in a removal station and placing the objects into the conveying device. In the conveying device, the objects are fed in succession to a first weighing station and weighed, to filling station and filled and to a second weighing station and again weighed and to a closing station and/or crimping station and closed. After closing, the objects are removed from the conveying section. In every case, pre-sterilized objects are processed in an aseptic manner.

A real-time calibration system and method for a mobile device having an onboard magnetometer uses an estimator to estimate magnetometer calibration parameters and a magnetic field external to the mobile device (e.g., the earth magnetic field). The calibration parameters can be used to calibrate uncalibrated magnetometer readings output from the onboard magnetometer. The external magnetic field can be modeled as a weighted combination of a past estimate of the external magnetic field and the asymptotic mean of that magnetic field, perturbed by a random noise (e.g., Gaussian random noise). The weight can be adjusted based on a measure of the statistical uncertainty of the estimated calibration parameters and the estimated external magnetic field. The asymptotic mean of the external magnetic field can be modeled as a time average of the estimated external magnetic field.

Exemplary systems, methods and computer-accessible mediums can be provided for imaging at least one anatomical structure. For example, it is possible to direct a saturation-recovery (SR) pulse sequence having fast spin echo (FSE) to or at the anatomical structure(s). At least one T₁ image of the at least one anatomical structure can be generated based on the SR pulse sequence. In one example, the anatomical structure(s) can include a hip. According to another example, T₁ image(s) can include a plurality of T₁ images generated or provided in a plurality of rotating radial planes.

A spinal construct for implantation in a patient to provide stabilization to spinal structure with improved load sharing includes a flexible spinal rod having a first end and a second end, the spinal rod being configured to provide stabilization to spinal structure. It also includes a first bone fastener configured to securely attach to the flexible spinal rod and a second bone fastener configured to securely attach to the flexible spinal rod. The second bone fastener is a dynamic fastener arranged to provide motion in one direction more than another direction. The flexible spinal rod and the second bone fastener are oriented to cooperate in a manner that achieves load sharing by dynamically flexing under applied loads in a manner that distributes stresses and strains between the flexible spinal rod and the second bone fastener.

An information handling system input device coordinates presentation of keyboard augmentation panels proximate a keyboard resting on a horizontally-disposed touchscreen display. The keyboard augmentation panels relate keyboard and other inputs to an application active on the information handling system to enhance end user interactions. A keyboard augmentation module tracks the keyboard position on the touchscreen display to adapt content presentation in the keyboard augmentation panels based upon expected end user inputs. In other embodiments, other physical devices are augmented to have hybrid graphical interfaces that enhance multi-hand end user interactions.

An electronic subassembly comprises a printed circuit board and an electronic module, particularly a ceramic module, electrically connected to one another through a planar interposer. The interposer comprises an insulator sheet and electrical spring elements joining contact sites on the module with contact pads on the PCB. The invention includes modifications that improve the integrity of electrical connections between the printed circuit board and the electronic module. This is achieved by compensating for non-planarity between the surfaces of the interposer and the module, particularly resulting from a convex curvature of the module, by minimizing relative movement, such as rocking in the x-z and y-z planes. It also includes modifications to the suspension of the module within the interposer housing to reduce the effects caused by any sliding that may occur between the interposer and the module in the x-y plane.
