Publication number: 20230367433Abstract: Computing devices and methods are used to detect and compensate for the presence of a cover layer on a touch input device. A computing device includes a processing device, a touch input device in electronic communication with the processing device, and a memory device in electronic communication with the processing device and having electronic instructions encoded thereon. The electronic instructions, when executed by the processing device, cause the processor to receive a first signal obtained from the touch input device over a first duration of time, the first signal including a first signal pattern, receive a second signal obtained from the touch input device over a second duration of time separate from the first duration of time, the second signal including a second signal pattern, determine a difference between the first signal pattern and the second signal pattern, and adjust a touch input detection setting based on the difference.Type: ApplicationFiled: July 28, 2023Publication date: November 16, 2023Inventors: Guangtao Zhang, Apexit Shah, Heemin Yang, Kevin D.

Patent number: 11762508Abstract: Grip detection can be beneficial for an electronic device to ignore unintended contacts on a touch sensitive surface. Examples of the disclosure provide various ways for identifying an input patch as a grip. In some examples, identifying an input patch as a grip comprises determining whether the input patch satisfies one or more grip identification criteria. In some examples, identified grips are saved in a grip database. In some examples, the identified grips are filtered out of touch images. In some examples, when baseline touch data for a touch-sensitive is updated, the touch processor can forgo updating the baseline for portions of the touch sensitive surface associated with the identified grips.Type: GrantFiled: February 16, 2022Date of Patent: September 19, 2023Assignee: Apple Inc.Inventors: Mayank Garg, Apexit Shah

Patent number: 11396585Abstract: A method of forming a void, channel and/or vascular network in a polymeric matrix comprises providing a pre-vascularized structure that includes a matrix material and a sacrificial material embedded in the matrix material in a predetermined pattern, where the matrix material comprises a monomer and the sacrificial material comprises a polymer. A region of the matrix material is activated to initiate an exothermic polymerization reaction and generate a self-propagating polymerization front. As the polymerization front propagates through the matrix material and polymerizes the monomer, heat from the exothermic reaction simultaneously degrades the sacrificial material into a gas-phase and/or liquid-phase byproduct. Thus, one or more voids or channels having the predetermined pattern are rapidly formed in the matrix material.Type: GrantFiled: March 5, 2020Date of Patent: July 26, 2022Assignee: THE BOARD OF TRUSTEES OF THE UNIVERSITY OF ILLINOISInventors: Nancy R.
