Patent number: 9769364Abstract: An audio capture system for a sports camera includes at least one “enhanced” microphone and at least one “reference” microphone. The enhanced microphone includes a drainage enhancement feature to enable water to drain from the microphone more quickly than the reference microphone. A microphone selection controller selects between the microphones based on a microphone selection algorithm to enable high quality in conditions where the sports camera transitions in and out of water during activities such as surfing, water skiing, swimming, or other wet environments.Type: GrantFiled: March 28, 2016Date of Patent: September 19, 2017Assignee: GoPro, Inc.Inventors: Zhinian Jing, Ke Li

Patent number: 9737242Abstract: Devices, systems and methods are described that can facilitate recognition of an engagement between an object and a touch screen in the absence of human contact. Upon the engagement, an electrically conductive path can be established that extends from a surface of the touch screen such that sufficient electrons flow from the touch screen through the electrically conductive path to enable the recognition of the object on the touch screen in the absence of human contact with the object during continued presence of the object on the touch screen.Type: GrantFiled: October 1, 2014Date of Patent: August 22, 2017Assignee: The Cleveland Clinic FoundationInventors: Jay L. Alberts, David D. Schindler

Patent number: 9727198Abstract: Methods and apparatus are provided for determining an input position of a touch object. An input signal is received from the touch object, and one or more sensing signals are output. A resistance of each of one or more sub-loops is measured, and a resistance information lookup table is generated with each resistance value of a corresponding sub-loop of the one or more sub-loops. The one or more sensing signals are corrected based on the resistance information lookup table. The input position of the touch object is determined based on the corrected one or more sensing signals.Type: GrantFiled: February 5, 2013Date of Patent: August 8, 2017Assignee: Samsung Electronics Co., LtdInventors: Byung-Jik Kim, Kwang-Choon Kim
