Patent number: 11620021Abstract: Cross-coupling correction techniques on a touch sensor panel can be improved using machine learning models (particularly for touch sensor panels with relatively low signal-to-noise ratio). In some examples, the machine learning model can be implemented using a neural network. The neural network can receive a touch image and perform cross-coupling correction to mitigate cross-talk due to routing traces of the touch sensor panel. Mitigating cross-talk can improve touch sensing accuracy, reduce jitter, and/or reduce false positive touch detection.Type: GrantFiled: September 14, 2020Date of Patent: April 4, 2023Assignee: Apple Inc.Inventors: Sai Zhang, Behrooz Shahsavari, Ari Y.

Patent number: 11269454Abstract: Structured noise from various aggressors can be suppressed to improve touch performance. A respective noise characteristic can be determined for each respective group of touch nodes (e.g., row, column) among multiple groups of touch nodes in a masked touch image. The respective noise characteristic can be removed from the corresponding respective group of touch nodes in the touch image. For example, a respective noise characteristic can be determined for each respective row and/or for each respective column in the masked touch image. The respective noise characteristic can be removed from the respective row and/or column in the unmasked touch image. In some examples, the determining and subtracting of the noise characteristic can be repeated iteratively within a window of time and/or until one or more noise criteria are met.Type: GrantFiled: February 17, 2021Date of Patent: March 8, 2022Assignee: Apple Inc.Inventors: Judd E.

Publication number: 20220011920Abstract: Techniques for rejecting apparent (but false) touches caused by objects such as water droplets located in areas with parasitic capacitive paths to ground are disclosed. To minimize these false touches, one or more guard conductors can be located in proximity to the housing and driven with a stimulation signal to shield objects from being capacitively coupled to ground through the housing. In some examples images of touch can be obtained from a non-bootstrapped or bootstrapped scan and also an extended bootstrapped scan wherein the guard conductor is driven with a stimulation signal that has the same characteristics as the stimulation signal being applied to the sensed touch nodes. In some examples, the results of the extended bootstrapped scan can be subtracted from the non-bootstrapped or bootstrapped scan to identify and reject apparent touches resulting from capacitive coupling to ground.Type: ApplicationFiled: September 25, 2021Publication date: January 13, 2022Inventors: Andrew William SHORTEN, Sai ZHANG, Andreas Johannes KOEBERL, Eric S.

Patent number: 10831296Abstract: Touch input processing for touch-sensitive devices can be used to filter unintended contact detected on a touch-sensitive surface. Moist or wet fabrics on the edge of a touch-sensitive surface can be erroneously be detected as touch input and degrade touch performance. In some examples, input paths can be classified as touch paths or non-touch paths (corresponding to wet fabrics). Non-touch paths can be filtered out to avoid unintended input to a touch-sensitive device. Classifying paths can improve touch performance in environments where a wet fabric may come in contact with the edge of the touch-sensitive surface. In some examples, paths can be classified as touch paths or non-touch paths based on characteristics of edge touch nodes. In some examples, paths can be classified as touch paths or non-touch paths based on a determined state.Type: GrantFiled: February 1, 2019Date of Patent: November 10, 2020Assignee: Apple Inc.Inventors: Sai Zhang, Ari Y.

Patent number: 10642418Abstract: Touch input processing for touch-sensitive devices can be improved by filtering unintended contact detected on a touch-sensitive surface. In wet environments in particular, water on the touch-sensitive surface can be erroneously detected as touch input and degrade touch performance. In some examples, input patches can be classified as touch patches or non-touch patches prior to computationally-intensive touch processing. Filtering out unintended touches classified as non-touch patches can reduce processing requirements and save power. Additionally, classifying input patches can improve touch performance in wet environments. In some examples, input patches can be classified as touch patches or non-touch patches based on characteristics of edge touch nodes. In some examples, input patches can be classified as touch patches or non-touch patches based on a state-based signal threshold.Type: GrantFiled: August 25, 2017Date of Patent: May 5, 2020Assignee: Apple Inc.Inventors: Apexit Shah, Ari Y.

Patent number: 10620758Abstract: The dynamic adjusting of the conditions for identifying inputs as touching a touch-sensitive device is discloses. In some examples, in addition to using a signal density make threshold to identify an input patch as touching the surface, a signal density stability threshold can be used to identify the input patch as touching the surface. In some examples, a weighted average of peak signal density contributions from recent identified touches can be computed to dynamically adjust the make threshold for new input patches. In other examples, a new input patch identified as associated with the same path as an earlier touch can have its “make” threshold dynamically adjusted based on the earlier touch without computing a weighted average.Type: GrantFiled: May 30, 2017Date of Patent: April 14, 2020Assignee: Apple Inc.Inventors: Ari Y.

Patent number: 10592027Abstract: A touch sensitivity of a touch-sensitive surface can be adjusted based on a state of a device including the touch-sensitive surface. The state of the device can be a first state or a second state. In the first state, for example, the touch sensing system of the device can be programmed to recognize and process a wide range of touch signals including relatively weak touch signals, which may correspond to water, liquid or other unintentional touches. In the second state, for example, the touch detection threshold can be adjusted to better reject water or unintended touches. In some examples, a ratio of measurements captured using the different types of scans of a selected touch node can be used to determine the state of the device.Type: GrantFiled: September 11, 2017Date of Patent: March 17, 2020Assignee: Apple Inc.Inventors: Sai Zhang, Branislav Jovanovic, Sean E.
