  • Patent number: 9367181
    Abstract: The embodiments described herein provide devices and methods that facilitate improved performance. In one embodiment, an input device comprises a processing system, a transmitter sensor electrode, and a receiver sensor electrode, where the transmitter sensor electrode and the receiver sensor electrode are capacitively coupled. The processing system is configured to receive a resulting signal from the receiver sensor electrode, where the resulting signal includes responses that correspond to the transmitter signal. The processing system is further configured to separately accumulate, for each cycle of the transmitter waveform, a first portion and a second portion of the resulting signal to respectively produce a first accumulation and a second accumulation, wherein the first accumulation is used for determining user input to the input device and the second accumulation is used for determining interference, and wherein the first portion and the second portion are non-coterminous.

  • Publication number: 20160142905
    Abstract: The disclosure relates to creating a time-sensitive grammar. A device receives a plurality of data points, identifies a plurality of time gaps associated with the plurality of data points, each of the plurality of time gaps representing a dwell time or a frequency of occurrence of a data point of the plurality of data points, generates a generic time factor representing a multiple of the plurality of time gaps, and combines the generic time factor with the plurality of data points to create a time-sensitive sequence of data points. The generic time factor may be inserted into the time-sensitive sequence a number of times representing the dwell time or the frequency of occurrence of a corresponding data point of the plurality of data points.

  • Patent number: 9317158
    Abstract: Embodiments of the invention generally provide a method and system that is able to minimize or remove the affect of substantially non-random electrical interference on an input device's ability to reliably and accurately sense the position of an object. In one embodiment, the input device is configured to systematically correct for a cyclic variation in the electromagnetic interference (EMI) generated by components within the electronic system, such as interference generated by the process of refreshing or updating an image on a display module that affects the capacitive sensing measurements acquired from a plurality of capacitive sensing elements. However, in some embodiments of the invention, the performance of an input device is improved by reducing the affect that external interference generated outside of the electronic system have on the position sensing data acquired by the input device.

  • Patent number: 9304643
    Abstract: Embodiments of the invention generally provide an input device that includes a zero-dimensional button that detects whether an input object is proximate to a sensing region. However, different input objects may provide similar responses which may prevent the input device from accurately determining whether the user actually intended to activate the button. In one embodiment, the input device drives a capacitive sensing signal onto a sensor electrode in the capacitive button and measures at least two resulting signals. The input device then derives capacitance values based on the two resulting signals and uses a ratio between the capacitance values to classifying the interaction with the input object. This ratio enables the input device to distinguish between events that have similar capacitive responses and would otherwise be indistinguishable if only one resulting signal were measured.

  • Patent number: 9274662
    Abstract: Embodiments in the present disclosure use various individual electrodes in a capacitive sensing pixel of an electrode matrix to perform two different techniques of capacitive sensing. For example, a capacitive sensing pixel may include at least two sensor electrodes that may be driven different by a processing system depending on the current capacitive technique being used to user interaction. When performing absolute capacitive sensing, a first one of the sensor electrodes may be driven with a modulated signal in order to measure a change in absolute capacitance between the driven sensor electrode and an input object. Alternatively, when performing transcapacitance sensing, the first sensor electrode is driven with a transmitter signal while a resulting signal is measured on a second sensor electrode in the capacitive pixel. In this manner, the individual electrodes in a capacitive sensing pixel may be driven differently depending on the current capacitive sensing technique.

  • Publication number: 20150346862
    Abstract: Disclosed herein are techniques for reducing certain types of noise in capacitive sensing devices. The techniques generally comprise utilizing a low-pass filter in conjunction with a comb filter to “zero out” frequency components associated with certain types of noise. More specifically, the comb filter is configured to zero out noise associated with the fundamental frequency and harmonics of noise that approximates a square wave or an impulse train. The frequency of the sensing signal for capacitive sensing is chosen such that the comb filter does not zero out such frequency.

  • Publication number: 20150323578
    Abstract: A capacitance measurement circuit comprises a differential amplifier with first and second inputs and an output, first and second feedback capacitances, and a reset mechanism. The first input is coupled to a modulated reference voltage and the second input is coupled with a sensor electrode. A first feedback capacitance is coupled between the output and the second input. A second feedback capacitance is coupled between the output and the second input. The reset mechanism resets the first feedback capacitance to a first level of charge and the second feedback capacitance to a second level of charge. During an absolute capacitance measurement phase, the differential amplifier charges the sensor electrode while balancing voltages on the first and second inputs to a voltage level associated with the modulated reference voltage and integrates charge on the sensor electrode to measure capacitance corresponding to a coupling between the sensor electrode and an input object.
