Patent number: 11723465Abstract: A display board, for writing and drawing with an interchangeable whiteboard, blackboard, or electronic surface that is pressure sensitive to a marker, chalk, or stylus through the use of a pressure sensitivity matrix. A software system implemented with the pressure sensitive matrix will be able to learn from the user's natural writing behavior, natural spaces and pauses in writing, and their writing size, and with these metrics, will be able to identify or predict a long pause in the action of writing. When this pause happens, the surface physically shifts upwards through the use of two linear actuators; the shift amount being determined by the user's writing size. The board is also able to shift upwards once the writer progresses to the opposite vertical edge of the drawing surface or can shift either upwards or downwards manually with two buttons on the side of the board.Type: GrantFiled: July 10, 2020Date of Patent: August 15, 2023Inventor: Nadun Gajapala

Patent number: 11669199Abstract: Acoustic touch and/or force sensing system architectures and methods for acoustic touch and/or force sensing can be used to detect a position of an object touching a surface and an amount of force applied to the surface by the object. The position and/or an applied force can be determined using time-of-flight (TOF) techniques, for example. Acoustic touch sensing can utilize transducers (e.g., piezoelectric) to simultaneously transmit ultrasonic waves along a surface and through a thickness of a deformable material. The location of the object and the applied force can be determined based on the amount of time elapsing between the transmission of the waves and receipt of the reflected waves. In some examples, an acoustic touch sensing system can be insensitive to water contact on the device surface, and thus acoustic touch sensing can be used for touch sensing in devices that may become wet or fully submerged in water.Type: GrantFiled: October 8, 2021Date of Patent: June 6, 2023Assignee: Apple Inc.Inventors: Marduke Yousefpor, Mohammad Yeke Yazdandoost, Aaron Scott Tucker, Marcus Yip, Ehsan Khajeh, Brian Michael King, Giovanni Gozzini
