Abstract: Systems and methods for protecting access to network ports on a server are provided herein. A system comprises a server configured to receive a data packet comprising a cryptoken corresponding to a network port address. The server is further configured to generate a plurality of cryptokens based on a plurality of timecodes, a network port configuration, and the destination address. The server generates a plurality of hashes based on the plurality of cryptokens. The server generates, based on a comparison of each of the plurality of cryptokens to the cryptoken, a rule to allow inbound connections to a first network port corresponding to the network port address.

Abstract: Systems, methods and non-transitory computer readable media for editing user interfaces from free text and/or sketches are provided. Digital data associated with a design of a user interface may be received. A presentation of the user interface based on the design may be caused. A selection of a portion of the user interface may be received. A textual input in a natural language and/or a sketch may be received. The textual input and/or the sketch may be analyzed to determine at least one change to a portion of the design of the user interface corresponding to the selected portion of the user interface. The determined at least one change may be implemented to generate a modified design of the user interface. A second presentation of the user interface based on the modified design may be caused.

Abstract: A method of ablating tissue includes positioning a treatment device proximate to a target tissue area. The treatment device has an expandable treatment element. The expandable treatment element is inflated with a refrigerant during an inflation phase such that at least a portion of the expandable treatment element is in contact with the target tissue area. A first pressure measurement of the inflated expandable treatment element is recorded and compared to a predetermined pressure threshold. The refrigerant is circulated within the expandable treatment element during an ablation phase to reduce a temperature of the target tissue area to a temperature sufficient to cryoablate the target tissue area. A second pressure measurement of the expandable treatment element is recorded during the ablation phase and compared to the predetermined pressure threshold.

Abstract: A system, method and leak signal discriminator for detection of a leak or mechanical breach in a catheter shaft in the presence of an electrical interferer are disclosed. According to one aspect, a leak signal discriminator having a leak detection circuit is configured to distinguish between a leak signal arising from a leak in a catheter and an interfering signal arising from an electrical interferer.

Abstract: A system and method for the safe delivery of treatment energy to a patient, which includes verification of system integrity before, during, or after the delivery of treatment energy and provides several mechanisms for rapid termination of the delivery of potentially harmful energy to the patient when a fault condition in the device and/or system is identified. The system may include an energy generator having processing circuitry to determine if there is a fault condition in the system and to automatically terminate a delivery of treatment energy when the processing circuitry determines there is a fault condition. The method may generally include performing a series of pre-checks, synchronizing a treatment energy delivery to the proper segment of the heart's depolarization pattern, configuring the system for treatment energy delivery, delivering the treatment energy, and performing post-treatment evaluation.

Abstract: XHD video is acquired from a camera fitted with an ultra-wide field-of-view lens such as a fish eye lens. The active picture portion of the images are divided into patterns each having a plurality of pixels. The patterns are assigned coordinate values and then reformatted into HD format using an encryption key which reorders the patterns. The images are processed in the HD format and then returned to XHD formation by applying the reverse reordering process under the control of the key.

Abstract: A method and system for scrambling visual information are, described. An image, preferably in an incompressed format, is divided into a number of patterns having a different aspect ratio. Each pattern is mapped on a matrix i.e positioned on X and Y-axis. The patterns are then arranged in a different and new shape for e.g. a rectangle, preferably, fitting the size of manoblocks in a MPEG video, to that of the original shape of the image but having the same number of patterns or same area. The patterns of pixels are then relocated in the new shape and a matrix is again mapped for the new arrangement of patterns. A key is then generated comprising the information of the encrypted and earlier image. The player decrypts the encrypted visual content or image by means of the information provided by the key.

Abstract: A method and system for encoding visual information are described. An image is divided in to n number of patterns. Each pattern is mapped on a matrix i.e positioned on X and Y-axis. The patterns are then arranged in a different and new shape for e.g. a rectangle, to that of the original shape of the image but having the same number of patterns or same area. The patterns of pixels are then relocated in the new shape and a matrix is again mapped for the new arrangement of patterns. A key is then generated comprising the information of the encrypted and earlier image. In order to decrypt the encrypted visual content or the encrypted image, the player reads the key or encrypted visual content and decrypts the encrypted visual content or image by means of the information provided by the key.

Abstract: A method and system for stitching two or more images to generate a resultant image of good quality is disclosed. The disclosed method and system represents a way to stitch two or more images captured through fisheye lenses. The method and system converts two fisheye hemispherical images to two triangles, which are thereafter stitched together to form a rectangular image. Herein each single pixel in the hemispherical images at the beginning represents one single pixel in the resultant rectangular figure at the end of the process. Thus, the resultant stitched image comprises of the same concentration of pixels at the end as was in the initial images to be stitched and occupies lesser storage space than equirectangular images or videos.

Abstract: Multiple image streams may be acquired from different sources. The colour depth of the images is first reduced and the streams then combined to form a single stream having a known format and bit depth equal to the sum of the bit depths of the reduced bit streams. Thus, the multiple streams may be processed as a single stream. After processing, the streams are separated again by applying a reverse reordering process.

Abstract: In a video-on-demand system, memory-based video streams are seamlessly replaced with disc-based video streams. This is achieved by first switching each memory-based video stream to a mixed video stream; and later, switching each mixed video stream to a disc-based video stream.

Abstract: A control program for a co-processor in a video-on-demand system directs the co-processor to perform the steps of: a) obtain a transmission control list, from an external source, which identifies a group of several video data packets and a respective subgroup of internet protocol headers for each video data packet in the group; b) partition into pieces, each video data packet and its respective subgroup of internet protocol headers as identified by the transmission control list; and, c) send the partitioned pieces, along with an additional header for each piece, to an output port during a series of spaced apart time intervals.

Abstract: A control program for a supervisor processor in a video-on-demand system directs the supervisor processor to perform the steps of: a) transfer a group of video data packets, from an externally stored complete video into a memory for the supervisor processor; b) build in the supervisor processor's memory, a respective subgroup of internet protocol headers for each video data packet in the group; and c) construct, in the memory of a co-processor, a transmission control list which indicates how each video data packet in the group, and its respective subgroup of internet protocol headers, can be accessed from the supervisor processor's memory by the co-processor.
