Abstract: Disclosed embodiments relate to a systems and methods of identifying a target object in an image using image processing. Template data is stored which represents a template orientation field indicative of an orientation of each of a plurality of features of a template object. Image data may be received and processed to generate an image orientation field indicating an orientation corresponding to the plurality of image features. The image data may be further processed to generate image confidence data based on at least one characteristic for use in identifying the target object in a given image, and the characteristic may be indicative of an increased likelihood that at least one part of the given image represents at least part of the target object, relative to other parts of the given image.

Abstract: Disclosed in this specification is a casting cup assembly comprising frontcurve and basecurve molds which of which includes a ring that circumscribes the respective concave and convex mold surface. When the casting cup is assembled, the rings align and minimize de-centering and tilting of the concave and convex mold surfaces which, in turn, reduces edge defects.

Abstract: The present invention provides ophthalmic devices comprising at least one photochromic material which is an indeno-fused naphthopyran having a pi-conjugation extending group bonded to the 11-position of the indeno-fused naphthopyran, the pi-conjugation extending group having at least one pendent halo-substituted group bonded thereto. The pi-conjugation extending group extends the pi-conjugation system of said indeno-fused naphthopyran. The 13-position of the indeno-fused naphthopyran is substantially free of spiro-substituents. The invention further provides photochromic materials of specified structure, photochromic compositions, photochromic articles and optical elements that include the photochromic materials. Other non-limiting embodiments relate to methods of making the ophthalmic devices comprising photochromic materials.

Abstract: A capsule camera includes a wireless transmitter that transmits data and a receiving system having multiple receiving units to allowing storing multiple data streams simultaneously. The multiple stored data streams may be used at a later time to derive the best data stream for analysis, based on the network conditions at the time each data packet is received. The best data stream may be derived from the multiple stored data streams at a later time during the decoding process. For example, in a capsule camera application, the multiple data streams may be stored in the memory devices associated with the receiving units, which are typically attached to different locations on the body during diagnosis. The multiple data streams are maintained as the capsule passes through the gastrointestinal tract. Subsequently, after the diagnosis, the receiving units are recovered and connected to a computer or another standalone device for analysis.

Abstract: A pressure and a vision regulation method and device for irrigation of a body cavity (1), in which an inflow liquid pump (2) pressurizes the irrigation liquid in a feed line (13) and an outflow device (3) or an external suction source (20) drains the irrigation liquid from the body cavity (1) through a tubing (16) into a waste container (17). A control unit (4) controls either the inflow liquid pump (2) only or both the inflow liquid pump (2) and the outflow device (3) depending on an inflow irrigation liquid pressure from a pressure sensor (5). The method and the device are combined with a method for detecting blood cells, red blood cells, haemoglobin and/or debris in liquid coming from a surgical site to provide an automatic control and rinsing system with clear vision in the viewing area of the operational site.
