Patent number: 11963691Abstract: A surgical instrument, has an end effector that includes an ultrasonic blade, and a clamp arm that moves relative to the ultrasonic blade from an opened position toward an intermediate position and a closed position. The clamp arm is offset from the ultrasonic blade to define a predetermined gap in the intermediate position between the opened position and the closed position. A clamp arm actuator connects to the clamp arm and moves from an opened configuration to a closed configuration to direct the clamp arm from the opened position toward the intermediate position and the closed position. A spacer connects with the clamp arm to inhibit movement of the clamp arm from the intermediate position toward the closed position for maintaining the predetermined gap between the clamp arm and the ultrasonic blade.Type: GrantFiled: December 21, 2020Date of Patent: April 23, 2024Assignee: Cilag GmbH InternationalInventors: Ryan M.

Patent number: 9084140Abstract: An IP address pool monitor is communicatively coupled to a communication link carrying packets between a mobile wireless communication network and a wide area network. The pool monitor receives requests transmitted by mobile devices over the communication link to the wide area network, and stores a record for each request. The pool monitor also receives responses transmitted back to the mobile devices responsive to each request. Each mobile device is assigned an IP address from one of a plurality of IP address pools. Upon receiving a response, the pool monitor identifies the IP address pool that includes the IP address of the mobile device associated with the request responsive to which the response was transmitted. The pool monitor then calculates a performance statistic for the identified IP address pool based on the stored record of the request and the received response.Type: GrantFiled: July 9, 2013Date of Patent: July 14, 2015Assignee: Cellco PartnershipInventor: David E.

Patent number: 8102419Abstract: An improved method and apparatus for scanning of anamorphic film utilizes increased number of scans and combination of scan lines for video output generation. A progressive raster scan is made of the film and stored in a frame memory. The spacing between the scan lines is made smaller than for the conventional scanning of an anamorphic image. In the preferred embodiment, the spacing between the scan lines for a 2:1 anamorphic image equals the spacing for scanning of a non-anamorphic image. The scan lines are retrieved from the memory and combined, preferably with the two nearest neighbors of the scan line. Optionally, the combined lines are weighted, preferably with the center scan line having larger weight. Subsequent video output lines are formed by repeating the process. Progressive video output or interlace output is provided as desired.Type: GrantFiled: May 24, 1993Date of Patent: January 24, 2012Assignee: Deluxe Media Services LLCInventors: David E.

Patent number: 7139029Abstract: Systems and methods are provided for allowing a user to correct a discontinuous 2-3 field sequence within a disrupted video signal. A 2-3 field pattern fixer can be operated in a one-pass mode and/or a two-pass mode. In the one-pass mode, the disrupted video signal is analyzed to generate correction information, which is used to correct the disrupted video signal as it passes through the 2-3 pattern fixer, resulting in an undisrupted video signal with a continuous 2-3 field sequence. In the two-pass mode, the disrupted video signal is analyzed to generate correction information, which is then stored. This correction information is then used to correct a duplicate of the disrupted video signal, resulting in an undisrupted video signal with a continuous 2-3 field sequence. In this connection, the 2-3 field pattern fixer includes a field sequence detector, a field sequence analyzer, a field sequence generator and a multiple delay tap circuit.Type: GrantFiled: May 5, 2003Date of Patent: November 21, 2006Assignee: Ascent Media Group, Inc.Inventors: David E. Holland, Gavin W. Schutz, Merle C. Sharp

Patent number: 5412433Abstract: An improved method and apparatus for color correction normalizes two of the three color signals as a function of the third. In the preferred embodiment, an image comprising red, green and blue (RGB) signals are converted to a luminance Y signal, a saturation signal and a hue signal. The luminance and saturation signals are normalized as a function of hue. In the most preferred embodiment, for all fully saturated colors, the luminance values are normalized to a value of 0.5, and the saturation values to unity for all values of hue. The normalized values of saturation and luminance are utilized with the hue value in a secondary color corrector. The color corrected values of saturation and luminance are denormalized as a function of color corrected hue. Optionally, the color corrected luminance, saturation and hue may be converted to RGB signals for output. In one aspect of this invention, the normalized luminance signal is not used for relatively small values of saturation.Type: GrantFiled: August 2, 1993Date of Patent: May 2, 1995Assignee: Image Transform Inc.Inventors: David E.

Patent number: 4823204Abstract: A method and apparatus for correction of both horizontal and vertical film weave is disclosed in connection with continuous motion type moving beam recorder or playback devices such as electron beam or laser beam recorders or flying spot scanner or line scan telecines. Weave correction is accomplished by scanning the sprocket hole of the film and generating a correction signal to compensate for the film weave. The film weave is corrected by electronic weave correction as opposed to mechanical pin registration means. The sprocket hole is scanned in the vertical direction to locate the upper and lower edges of the sprocket hole, and then to position the beam in the vertical center of the hole and for determination of vertical weave of the film. The sprocket hole is then scanned in the hozizontal direction, for determination of the horizontal weave of the film.Type: GrantFiled: June 18, 1987Date of Patent: April 18, 1989Assignee: Image TransformInventor: David E.

Patent number: 4104680Abstract: A method and apparatus for film weave correction is disclosed in connection with a moving beam-type recorder or flying spot scanner device having a continuous-motion film drive in which the film is edge-guided rather than sprocket hole-guided as during playback. The film weave correction apparatus causes the beam to sweep, at least once for each frame being scanned, horizontally across a sprocket hole defined in the film adjacent to the frame. A detector behind the film detects the beams's crossing of the sprocket hole edge. The apparatus compares the time of occurrence of this edge crossing with a reference time and generates therefrom a film weave correction signal. This signal is applied to the horizontal deflection circuitry of the device and causes the beam to be shifted in such a way that the horizontal position of each scanned frame remains constant with respect to the position of the adjacent sprocket hole rather than with respect to the film edge or film guide.Type: GrantFiled: January 24, 1977Date of Patent: August 1, 1978Assignee: Ellanin Investments, Ltd.Inventor: David E.
