Abstract: System, device, and method for improved encoding and enhanced compression of images, videos, and media content. A method includes: (a) receiving a source image, and analyzing its content on a pixel-by-pixel basis, and classifying each pixel as either (I) a pixel associated with Photographic content, or (II) a pixel associated with Non-Photographic content; (c) generating a pixel-clusters map that indicates (i) clusters of pixels that were classified as Photographic content, and (ii) clusters of pixels that were classified as Non-Photographic content; (d) generating a composed image, by: (d1) applying a first encoding technique, particularly lossy encoding, to encode pixel-clusters that were classified as Photographic content; (d2) applying a second, different, encoding technique, particularly lossless encoding, to encode pixel-clusters that were classified as Non-Photographic content.

Abstract: A method and system are described where graphics, for example, fiducials, are placed within the context of panoramic video footage such that those graphics convey meaningful and relevant information, such as first down lines, sidelines, end zone plane (American football), three-point line (basketball), goal line (hockey, soccer), blue line (hockey), positional environmental, or biometric information. Graphics may also signify the status of event, such as whether a first down was made or whether a play was overturned. The system includes one or more cameras connected to a computer that also receives synchronized sensory data from one or more environmental or positional sensors. The fiducials may be based upon the content and context of the video, or augmented via the use of external sensors which may be aggregated by the computer, with graphics being generated and displayed on a frame-by-frame basis for the purposes of disseminating information and enhancing the live production.

Abstract: Systems, devices, and methods for determining color ambiguity of images or videos. A system includes a color ambiguity score generator, which analyzes an image and determines a color ambiguity score that quantitively indicates a level of color ambiguity that the image is estimated to cause when viewed by a user having color vision deficiency. A local color ambiguity score is generated to quantitively indicate a level of local color ambiguity between (i) an in-image object and (ii) an in-image foreground of that in-image object. A global color ambiguity score is generated to quantitively indicate a level of global color ambiguity between (I) a first in-image object within the image and (II) a second in-image object within that image. The color ambiguity score generator generates the color ambiguity score by utilizing a formula that uses both (A) the local color ambiguity score and (B) the global color ambiguity score.

Abstract: The disclosure relates to a method of manufacturing an implantable defibrillation coil for a lead of an active implantable medical device, the defibrillating coil includes at least one elongate conductive coil which includes a plurality of non-contiguous turns. The method includes inserting a tube of polymeric material within the elongated conductive coil, supplying thermal energy to soften the tube, applying pressure on the assembly formed by the elongate conductive coil and causing the tube to deform the tube wall by insertion of the tube wall between the turns of the elongate conductive coil.

Abstract: Systems and methods are provided for improving process control of separation systems that include one or more dividing walls within a single column. It has been discovered that improved process control can be achieved by controlling the dividing wall columns based on energy balance instead of mass balance. The energy balancing can be performed in part based on controlling temperature at a plurality of locations on the feed side within a first divided portion of the column. Using energy balancing based on temperature control at a plurality of locations on the feed side can facilitate maintaining the operation of the dividing wall columns within a single region of phase space that can be suitably approximated by linear models. This can allow conventional process controllers to manage the manipulated and controlled variables. In addition to controlling the temperature at a plurality of locations on the feed side, a plurality of other characteristics can be used as manipulated or controlled variables.

Abstract: An autonomous capsule includes a tubular body provided at its distal end with an anchoring screw, and in its proximal region of a capture groove. An explantation accessory includes a reinforced catheter combined with a flexible wire which can slide in the catheter and has a deformable loop which can be clamped by gradual introduction of its ends in the catheter under the effect of a traction exerted on the wire. During tightening, the capture groove receives the wire loop, allowing, after complete tightening, to secure in tension and rotation an assembly formed by the catheter, the capsule, and the wire. The reinforced catheter is then used to transmit a tensile force and an axial torque from its proximal end to its distal end, allowing safe unscrewing of the capsule and its extraction through the patient venous network.
