Patent number: 9576554Abstract: A digital magazine server determines a dominant color present in an image using a clustering algorithm. Color components of each pixel in the image are identified used to generate vectors associated with each pixel. Based on the vectors associated with the pixels, clusters including one or more pixels are generated using a clustering algorithm (e.g., k-means). The digital magazine server generates a characteristic vector for each cluster based on the vectors included in the cluster and selects a set of clusters based on their characteristic vectors. A centroid identifying the dominant color of the image is determined from the characteristic vectors of clusters in the set.Type: GrantFiled: December 15, 2014Date of Patent: February 21, 2017Assignee: Flipboard, Inc.Inventor: Meng Guo

Patent number: 9576555Abstract: Displays, display components, image and video processing apparatus and related methods are described. A method for driving local-dimming displays comprises generating control values for driving pixels of a spatial light modulator from one image data component and generating control values for driving backlight elements from a second image data component. The first and second image data components may respectively comprise a tone map and a ratio image. Control values for the spatial light modulator and/or backlight may be obtained using cost effective hardware.Type: GrantFiled: June 20, 2011Date of Patent: February 21, 2017Assignee: Dolby Laboratories Licensing CorporationInventors: Ajit Ninan, Wenhui Jia

Patent number: 9576557Abstract: Embodiments of the invention generally provide an input device with display screens that periodically update (refresh) the screen by selectively driving common electrodes corresponding to pixels in a display line. In general, the input devices drive each electrode until each display line (and each pixel) of a display frame is updated. In addition to updating the display, the input device may perform capacitive sensing using the display screen as a proximity sensing area. To do this, the input device may interleave periods of capacitive sensing between periods of updating the display based on a display frame. For example, the input device may update the first half of display lines of the display screen, pause display updating, perform capacitive sensing, and finish updating the rest of the display lines. Further still, the input device may use common electrodes for both updating the display and performing capacitive sensing.Type: GrantFiled: January 12, 2015Date of Patent: February 21, 2017Assignee: SYNAPTICS INCORPORATEDInventors: Jeffrey S. Lillie, John Childs, Christopher A. Ludden, Thomas Mackin, Petr Shepelev

Patent number: 9576559Abstract: The present invention provides a musical instrument manual having keys that may be made of a material subject to warping and twisting, such as wood. A distal flexible suspension allows angular shifting of the distal end of each key of the manual to accomodate key warping. The flexible suspension enables angular displacement of the key lever about its distal end perpendicular to the plane of the playing surface of the key to allow the key to be played. The flexible suspension elastically opposes twisting of the key lever relative to the key bed.Type: GrantFiled: June 15, 2016Date of Patent: February 21, 2017Inventor: William Henry Morong

Patent number: 9576561Abstract: A pick for use with stringed musical instruments is disclosed. In some embodiments the pick is characterized by a roughened texture on the front and back substantially planar surfaces of the narrowed bottom portion of a substantially teardrop shaped body for the purpose of altering the tonal properties produced as it moves against strings that are strummed or picked. In further embodiments the roughened textured picking portion is combined with a separate second picking portion that is substantially smooth and useable to produce a conventional sound.Type: GrantFiled: January 20, 2015Date of Patent: February 21, 2017Inventor: Jonathan Mark Thompson

Patent number: 9576562Abstract: A guitar hand placement guide and support bar that attaches to the upper surface of the body of a guitar with one or more suction cups. An upper platform portion in contact with lower, round portion of the palm of the hand supports the weight of the hand. The guitar hand placement guide and support bar has legs that straddle the strings at a location adjacent the sound hole of the guitar such that every time the guitar is being played, the pick and strum hand can be consistently positioned above the sound hole in precisely the same place. A dogleg extension and one or more internal finger grip portions located along the lower edge of the platform portion extending between the leading edge and the rear-facing edge provide the player with optional methods of use.Type: GrantFiled: August 16, 2016Date of Patent: February 21, 2017Inventors: Russell K. Porter, Jerrilyn J. Roblin-Porter

Patent number: 9576563Abstract: A percussion instrument, specifically a tank drum having tongues that form playing parts and including a ground clearance in its body, and a tuning structure which by changing the center of gravity of the tank drum, enables its tuning. A magnet is placed under the tongues. A channel is provided on the tongues enabling the magnet to be moved back and forth with the help of a key.Type: GrantFiled: January 29, 2014Date of Patent: February 21, 2017Inventor: Deniz Güngör
