Patent number: 11348264Abstract: A communication system captures writing surface content in a physical space for transmittal to remote client devices participating in a communication session. During a communication session with one or more remote client devices, a communication system captures image data and depth data describing objects in a physical space of the communication system. Based on the captured data, the communication system identifies a writing surface in the physical space and captures content on the writing surface. The communication system may also identify objects occluding content on the writing surface based on the captured data and may modify image data to make an object occluding the content at least partially transparent. The communication system transmits the content to at least one of the remote client devices participating in the communication session.Type: GrantFiled: April 23, 2020Date of Patent: May 31, 2022Assignee: Meta Platforms, Inc.Inventors: Tyler Back, Gabriel Molina

Patent number: 11231820Abstract: A touch sensing structure with improved illumination includes a first substrate, a decoration layer, a light-shielding layer, a light-emitting element, a pressure-sensitive element, a first reflective layer, and a second reflective layer. The pressure-sensitive element is farther away than the light-emitting element from the first substrate. The decoration layer shows a function icon. The light-emitting element emits light to illuminate the function icon. When the first substrate is pressed, the touch sensing structure determines a magnitude of the pressing force by detecting a change in the resistance or voltage value of the pressure-sensitive element. If the pressing force reaches a specific value, the function identified by the function icon is executed, otherwise no function is executed.Type: GrantFiled: April 13, 2021Date of Patent: January 25, 2022Assignees: Interface Technology (ChengDu) Co., Ltd., INTERFACE OPTOELECTRONICS (SHENZHEN) CO..

Patent number: 8154535Abstract: An image generating unit of a display apparatus generates a determination image based on first and second light reception images obtained from light reception cells in a light-emission period and in a non-light-emission period, respectively. An image determining unit determines whether or not an image of an object to be detected is included in the determination image, stores data corresponding to the determination image as initial data into a storage when the object image is not included in the determination image, and stores the data corresponding to the determination image as detection data into the storage when the object image is included in the determination image. A position determining unit determines at least an object position based on an image represented by the detection data in the storage and an image represented by the initial data in the storage.Type: GrantFiled: February 23, 2009Date of Patent: April 10, 2012Assignee: Sony CorporationInventors: Mitsuru Tateuchi, Tsutomu Harada, Kazunori Yamaguchi, Ryoichi Tsuzaki

Patent number: 8102378Abstract: A touch-sensing display screen includes an upper transparent substrate, a lower substrate opposite the upper substrate and an infrared light source configured to illuminate a portion of the upper transparent substrate. A light converting layer is disposed between the upper and lower substrate and is configured to convert the infrared light received by the upper transparent substrate to visible light. A pixel thin-film transistor on the lower substrate is configured to activate a pixel electrode, and a light-sensing thin-film transistor is configured to sense the visible light provided by the light converting layer. A light-sense signal is output in response to activation of the light-sensing thin-film transistor.Type: GrantFiled: September 26, 2007Date of Patent: January 24, 2012Assignee: LG Display Co., Ltd.Inventors: In Jae Chung, In Ho Ahn, Seong Ho Baik, Sang Hyuck Bae

Patent number: 8009152Abstract: A refined coordinate detection method for a touch panel, which more finely measures coordinates of an object without increasing the number of infrared emitting/receiving elements, and an error correction method, which minimizes position detection errors caused by received optical level errors due to external environment or their inherent characteristics, are provided. In the detection method, received levels of infrared emitting/receiving elements corresponding to left and right ends of object are measured and stored and the levels and a maximum received level are compared to calculate the refined coordinates. In the correction method, a lower limit level at a position where infrared reception is most significantly impeded by object is calculated through a comparison calculation of maximum and minimum received levels and it is detected that an object is present at a position only when a lower limit level at that position is not greater than the calculated one.Type: GrantFiled: November 23, 2006Date of Patent: August 30, 2011Assignee: Nexio Co., Ltd.Inventors: Kil-Sun Kim, Yong-Churl Kim

Patent number: 7995042Abstract: The dimension detection system is implemented in cascaded circuit boards housed inside a frame assembly of the touch screen. After the frame assembly is assembled and powered, the dimension detection system in the circuit boards would provide horizontal and vertical feedback signals which are utilized to obtain the size of the touch screen. The size information of the touch screen could then be provided to the computer or embedded system where the touch screen is connected, preventing troublesome manual configuration. The dimension detection system and the flexible frame assembly together make the touch screen's production, storage, transportation, and usage more efficient and friendly.Type: GrantFiled: April 17, 2008Date of Patent: August 9, 2011Assignee: ET&T Technology Co., Ltd.Inventors: Jung-Yu Chen, Chien-Ping Sun, Yi-Te Chien, Wei-Lin Wang
