A real-time system and method for inserting perspective correct content into an image sequence are presented. The invention inserts the content with the location, size, orientation, shape and occlusion properties that are appropriate for the camera view represented by the image sequence. Both static and dynamic content insert positions are supported. The location, size, orientation and shape of the inserted content are determined independently of the image sequence content. Furthermore, no knowledge of three dimensional real world space locations or real world measurements, as related to the content of the image sequence, is used during the content insert process.

A method and system for automatically determining the differences in a mobile device user interface throughout a development cycle. A test automation is run to exercise a target device's user interface. While the user interface is exercised, an extension is activated that takes snapshots of the user interface output at selected intervals of an automation execution. The snapshots are stored and uploaded to a server where snapshots of different automation executions are then compared on a pixel-by-pixel basis. The differences between snapshots are output in a visual format where the pixels that are different between snapshots are highlighted. The visual format of the differences between snapshots provides the user with a method to readily determine if errors exist in the user interface of the target device.

Described herein is the use of a fast-scanning optical phase array (OPA) within an electronic beam-steering-based aperture.

The present invention relates to an optical scanning probe assembly for microscopic guide optic scanning and inspection of tissues suitable for application in, e.g. in vivo medical inspection and biopsy. The assembly comprises an outer housing (3) comprising: i) a spring element for a scanning motor, the spring element formed as a hollow tube (5) adapted to receive an optical guide, the hollow tube having mechanical stiffness larger than the optical guide to be received, ii) a lens system (7) and iii) N means for deflecting (6) the distal end of the hollow tube in directions transverse to the longitudinal extension of the hollow tube, so as to form an optical scan pattern. The optical assembly is particularly advantageous as it increases the freedom to optimize the optical and mechanical performance of the system which is defined respectively by the optical guide and by the hollow tube. The probe can be used in resonant and non-resonant scanning modes.

The present invention relates to a method and arrangement for controlling exposure in an e-ray apparatus, for depicting an object. The apparatus comprises an x-ray source and a displaceable detector being arranged to move with a controllable speed across an image exposure area. The method comprises the step of: acquiring a signal relating to photons incident on at least a part of the detector, comparing said acquired signal with a target value, and controlling the speed of detector, displacement with respect to the result of the comparison.

A stack of polarization gratings each having a grating pitch, the stack having a first end and a second end and, the polarization grating stack including N stages wherein one or more of the N stages in the stack comprise a first set of gratings which direct an incident beam through angles lying substantially in a first plane and one or more of the N stages in the stack comprise a second set of gratings which direct an incident beam through angles lying substantially in a second, different, plane lying at an angle relative to the first plane and wherein each of the N stages provide one of a plurality of deflection angles and wherein the N stages are arranged such that a stage having the smallest deflection angle is nearest the first end of the stack and a stage having the largest deflection angle is nearest the second end of the stack and wherein the deflection angles of the gratings in each set are chosen such that the grating pitch of each grating is at least one of: substantially twice the grating pitch of another member of the set; or substantially one-half the grating pitch of another member of the set.

A wheel end for use in a vehicle wherein the wheel end includes a side shaft wherein the side shaft having an appendage on one end thereof. The side shaft having a cylindrical cavity at a center point of the appendage. The wheel end unit also includes a spindle arranged around the appendage. A knuckle is arranged around a portion of the spindle and a portion of the side shaft. The wheel end also includes a fastener secured between the spindle and the appendage to ensure a robust connection between the spindle and the appendage.

Devices and methods that prevent clotting of blood during blood-processing procedures such as hemofiltration, hemodialysis, hemodiafiltration, and peritoneal dialysis are described. The device comprises a cap and a housing that is shaped to receive a blood filter. The housing has an inlet for blood and may have an outlet for waste and ultrafiltrate. The cap is attached to the housing. The cap has an outlet for blood and a port adjacent the outlet for receiving dilution fluid. Methods of use during blood-processing procedures to provide immediate hemodilution to blood exiting a filter are also described.

An aseptic connector assembly and a method of aseptically transferring fluid are provided. The aseptic connector assembly includes a body portion, the body portion having a receptacle configured to receive a corresponding fill connector; a pivot portion adjustably disposed within and extending partially from the body portion, the pivot portion having a channel formed therein; and a conduit portion axially slidably disposed within the channel formed in the pivot portion. The pivot portion comprises a ready position and an operative position, the pivot portion being adjustable from the ready position to the operative position via relative movement with respect to the body portion. The method includes providing an aseptic connector in a ready position, coupling a flexible tubing and a fill connector to the aseptic connector, moving a pivot portion to an operative position, axially sliding the conduit portion into the fill connector, and transferring a fluid through the connector.

A demodulator, chip and method for digitally demodulating an FSK signal utilizing a digital data transfer protocol and a digital demodulator circuit have been developed. The data-rate approaches the carrier-frequency. The one application for this technique is in the magnetically powered wireless systems such as biomedical implants and radio frequency identification (RFID) tags with high data rates above 1 Mbps. The demodulator circuit extracts the serial data bit-stream and a constant-frequency clock from an FSK carrier signal in the 1˜20 MHZ range, which can power the wireless system as well. The digital demodulator circuit is implemented entirely with digital circuitry and is called a digital-FSK (DFSK) demodulator.
