    Abstract: A device to image registration method includes obtaining image data of a device, the device including a plurality of fiducials arranged as a fiducial frame on the device; detecting fiducial objects within the image data; cropping the image data to generate cropped image data; applying a feature enhancement to the cropped image data to enhance the fiducial objects; generating a candidate list of candidate objects based on the feature enhancement, and determining a common plane based on at least three points in the candidate list; determining a representative point for each candidate object; determining outlier candidate objects based on the common plane; determining resultant objects by extracting the outlier candidate objects from the candidate list; and registering the resultant objects to the device by matching the representative points of the resultant objects with a model of the fiducial frame.

    Abstract: An image processing apparatus and method are provided which obtains an image captured by an image capture device and stored in a memory, extracts one or more regions of interest in the obtained image, normalizes the extracted one or more regions of interest to be at a same scale or some predefined scales, extract the frequency information of regions of interest, determines a sharpness of the obtained image by aggregating the frequency information in each of the one or more extracted regions of interest, and labels the obtained image with the determined sharpness score.

    Abstract: A conveyance system for conveying a mold into an injection molding machine includes a conveying machine that conveys the mold, and a supporting member that movably supports the conveying machine, wherein the improvement to the conveyance system includes a guide member that guides a movement of the conveying machine by the supporting member in a direction other than an X-axis direction between a first position where the mold can be conveyed from the conveying machine to the injection molding machine and a second position that is different from the first position.

    Abstract: An optical connection includes a plurality of ferrules, an optical contact to allow transfer of light, a mechanical contact to allow torque transfer from the optical connection, and a rotational self-alignment structure to allow optical fibers of different optical connectors to self-rotate into rotational self-alignment upon action of connecting, wherein the ferrules are aligned and engage the torque transfer. The rotational self-alignment structure can be a tooth configuration, a helical thread configuration, a ferrule guide configuration, a spring sleeve configuration, derivatives thereof and combinations therefrom.

    Abstract: A handle for maneuvering a catheter, comprises: a handle body having an outer surface and an inner surface, the inner surface defining a tubular passage extending along a longitudinal axis from a proximal end to a distal end of the handle body. The handle includes a coupling mechanism at the proximal end and a strain relief sleeve at the distal end of the handle body. The strain relief sleeve is adapted to irremovably secure a flexible catheter sheath to the handle; and the coupling mechanism is adapted to detachably connect the handle to a patient interface unit (PIU). The handle body is ergonomically sized and shaped for grasping by a single hand of a user, and is configured to linearly engage to and disengage from the PIU via the coupling mechanism. When the handle is attached to the PIU, an imaging core moves linearly inside the tubular passage without bending.

    Abstract: An apparatus, method, and system for a steerable medical instrument, configured to be used in conjunction with guided tools and devices under robotically controller medical procedures, including endoscopes, cameras, cutting tools and catheters. In one embodiment, the steerable instrument includes an elongate body (100), a control wire (110) arranged in a channel (104) of the elongate body and displaceable along the channel to bend the elongate body; and a controller (320) to selectively control drive forces applied to the control wire (110) under an actively controlled mode and a passively controlled mode. In the actively controlled mode, the controller actively bends at least part of the elongate body. In the passively controlled mode, the controller (320) decreases an amount of strain or an amount of displacement of the control wire, so that the control wire becomes compliant to external forces.
