A multispectral X-ray imaging system uses a wideband source and filtration assembly to select for M sets of spectral data. Spectral characteristics may be dynamically adjusted in synchrony with scan excursions where an X-ray source, detector array, or body may be moved relative to one another in acquiring T sets of measurement data. The system may be used in projection imaging and / or CT imaging. Processed image data, such as a CT reconstructed image, may be decomposed onto basis functions for analytical processing of multispectral image data to facilitate computer assisted diagnostics. The system may perform this diagnostic function in medical applications and / or security applications.

An automatic repeater vaccinator apparatus (10) for dispensing a predetermined volume of a fluid into an animal, particularly a fluid which is a vaccine, and reloading after each volume of fluid is dispensed. The apparatus (10) comprises a handheld syringe (100) for dispensing the fluid, a flexible conduit (12) for transferring the fluid from a dispensing means to the syringe (100), and a reservoir (48) for providing the fluid to the dispensing means. The dispensing means is electrically activated by a magnetically closeable switch (preferably a reed switch (142)) in the syringe (100), which enables a predetermined volume of the fluid to be dispensed from the syringe (100) when the dispensing means is activated and reloading fluid from the reservoir (48) to replace the volume of fluid which has been dispensed from the syringe (100) when the dispensing means is deactivated. Preferably, the dispensing means comprises a pump (200 or 500) operated by a linear actuator such as a solenoid (300), which is electrically activated by the magnetically closeable switch in the syringe (100). The apparatus (10) is particularly useful for inoculating poultry, particularly inoculating the poultry by the wing web method using the needle and hub assembly (400) which comprises the filament (402) to prevent leakage between inoculations.

A system and method for developing customized apparatus, such as guides, for use in one or more surgical procedures is disclosed.

According to a preferred embodiment, the customized apparatus comprises at least one patient-specific surface and or contour, which may be derived from MRI or CT data. Apparatus may be matched in duplicate and oriented around the patient's own anatomy, and may further provide any desired axial alignments or insertional trajectories. In an alternate embodiment, the apparatus may further be aligned and / or matched with at least one other apparatus during the surgical procedure.

A linearly expanding spine cage has a minimized diameter in its unexpanded state that is equal to the diameter of an insertion groove cut into adjacent vertebral bodies. The cage conformably engages between the endplates of adjacent vertebrae to effectively distract the disc space, widen neuroforamina, stabilize the motion segments and eliminate pathologic spine motion. Angular deformities can be corrected, and natural curvatures maintained. The cage enhances spinal arthrodesis by creating a rigid spine segment. Expanding linearly (vertically, along the vertical axis of the adjacent spine) rather than uniformly, the cage height increases and holds the vertebrae with fixation forces greater than adjacent bone and soft tissue failure forces. Stability is thus achieved immediately, enabling patient function by eliminating painful motion. The cage width remains stable, so as to decrease impingement upon a second cage, or upon soft tissue structures in the immediate vicinity, including neural or vascular elements.

Devices for stabilizing tissue during a surgical procedure. The beating heart may be stabilized during a surgical procedure on the heart, using a described stabilizing device. In one example, a stabilizing device is introduced through an opening in the chest and brought into contact with the beating heart. By contacting the heart with the device and by exerting a stabilizing force on the device, the motion of the heart caused by the contraction of the heart muscles id effectively eliminated such that the heart is stabilized and the site of the surgery moves only minimally if at all.

The correspondingly aligned and shaped interior and exterior grip material segments on the wearable article may be arranged in different sizes and patterns to suit the movements typically executed during a particular physical or sporting activity.

A method of removing unwanted camera motion from a video sequence is provided. The method matches a group of feature points between each pair of consecutive video frames in the video sequence. The method calculates the motion of each matched feature point between the corresponding pair of consecutive video frames. The method calculates a set of historical metrics for each feature point. The method, for each pair of consecutive video frames, identifies a homography that defines a dominant motion between the pair of consecutive frames. The homography is identified by performing a geometrically biased historically weighted RANSAC on the calculated motion of the feature points. The geometrically biased historically weighted RANSAC gives a weight to the calculated motion of each feature point based on the historical metrics calculated for the feature point. The method removes he unwanted camera motion from the video sequence using the identified homographies.

Before an amount of play in a rotation transmitting system is learned, for selecting a gear range, an overshooting control process is performed to cause the angular displacement of a motor to overshoot a target gear range position and then reverse the electric motor. The angular displacement of the motor overshoots the target get gear range position by an overshooting amount that is identical to am amount by which the electric motor is reversed. The overshooting amount is set to a maximum value of a designed amount of play in the rotation transmitting system After the amount of play is learned, for selecting a gear range, a target count is established in view of the learned amount of play and the direction in which the motor rotates, and the motor is stopped at a position where an encoder pulse count coincides with the target count without performing the overshooting control process.

A hitch adapter comprises an inner square tube member for receiving Class-II 1.25″ drawbars and an outer U-channel member for plugging into a Class-III 2″ receiver. The inner square tube and outer U-channel members are welded together such that one wall of the inner square tube bridges the gap between the distal edges on opposite legs of the outer U-channel. One such leg of the outer U-channel is longer than the other and is positioned and aligned to protrude about 1 / 16″ beyond the adjacent outer corner of the inner square tube member. Such protrusion nests into the respective inside corner of the particular Class-III 2″ receiver it is mated to. The protrusion provides a camming action to take up any looseness and slack, and thereby eliminate wobble and rattle when installed by a user. A series of hitch pin holes allows a threaded hitch pin to pass through the adapter, a Class-II 1.25″ drawbar and a Class-III 2″ receiver. Threads inside the Class-II 1.25″ drawbar engage the hitch pin threads and provide the user a way to secure the whole assembly.
