Abstract: The technologies described herein identify multiple electronic devices belonging to the same group. A computer system receives, from network accessing applications of a plurality of electronic devices, internet protocol (IP) trajectory information about the network accessing applications via a network. The IP trajectory information includes a user identifier, a list of IP addresses associated with each of the network accessing applications, and timestamps specifying times each of the network accessing applications accesses the network. The computer system identifies and removes commercial IP addresses from the list of IP addresses, analyzes IP trajectory information to retrieve a most commonly used IP address for each of the network accessing applications during a certain period, and determines that different network accessing applications belong to the same group if the most commonly used IP addresses for the different network accessing applications are the same.

Abstract: A method of removing an appendix (9) includes the steps of accessing the abdomen of a patient, insufflating the abdominal cavity, and sealing and cutting the appendicular artery and vein. A sheath is introduced into the abdominal cavity and placed over the appendix, while the appendix is still attached to the colon. The sheath is secured the sheath in place over the appendix using a securing device to secure the sheath with respect to the proximal end of the appendix, and then the proximal end of the appendix is ligated. The appendix is dissected from the colon, and the sheath containing the appendix is removed from the abdomen of the patient. The procedure can be a NOTES procedure, using a natural orifice, or laparoscopic using one or more incisions created in the abdomen. The ligation and dissection can be performed within the abdomen, or after the appendix is pulled through one of the incisions, such that the ligation and/or dissection is carried out outside the abdomen.

Abstract: An electrosurgical generator for generating radio frequency power, includes a radio frequency output stage having three or more output connections, and one or more sources of radio frequency output power coupled to the output stage. A controller causes the system to supply a first coagulating RF waveform to the output connections or a second cutting RF waveform to the output connections. The first RF waveform is delivered between a first pair of the output connections, and the second RF waveform is delivered between a second pair of the output connections. In a first mode of operation the controller supplies the first coagulating RF waveform, and in a second subsequent mode of operation the controller supplies the second cutting RF waveform for a first predetermined period of time followed by the first coagulating RF waveform for a second predetermined period of time, both periods being in excess of 1 second.

Abstract: A graphics system reduces fetching from memory of color-key pixels when video pixels from a video-overlay window are displayed. A frame buffer is divided into multi-line, multi-pixel blocks that are arranged in block-rows and block-columns. Each block-row has primary and secondary row indicator bits and each block-column has two column indicator bits. When the primary row indicator bit is cleared, all pixels in the block-row are fetched from a frame-buffer memory. When the primary row indicator is set, a secondary row indicator bit selects either first or second column indicator bits for reading. When the selected column indicator bit for a block-column is set, fetching of pixels from the frame buffer memory is skipped. Instead, dummy color-key pixels are generated and inserted into the pixel stream. These dummy pixels match the color key and cause video pixels to be sent to the display. Memory fetching is reduced.

Abstract: A frame buffer stores X pixels per line and Y lines and is read using a burst of B pixels. The un-rotated image is rotated by 90 degrees for display by writing and reading pixels from a line buffer. The line buffer stores a block of B*Y pixels. The frame buffer is logically divided into X/B blocks that are B pixels wide. Blocks are read from the frame buffer from the bottom line to the top with a burst of B pixels per line. An offset locate pixels to read in the line buffer. The offset is B for the first block, and increases by a factor of B for each block read, but wraps around modulo B*Y?1. Pixels for a next block are written into the line buffer to locations vacated as pixels are read out. The increasing offset re-orders the pixels for the rotated display order.
