    摘要: One or more examples relate to a knob-on-display. An apparatus of such a knob-on-display includes a touch surface, a dome switch pad, a dome switch, a rotation electrode pad, and an electrically conductive structure. The touch surface may include an electrically conductive material, the touch surface movable to a released position and to a depressed position. The dome switch may include an electrically conductive material. The dome switch may be physically mounted to and electrically connected to the dome switch pad. The rotation electrode pad may be in engagement proximity to a touch sensor of a touch screen device in both the released position and the depressed position. The electrically conductive structure may be physically and electrically connected to the dome switch pad and the rotation electrode pad, the electrically conductive structure defining a continuous electrically conductive path from the rotation electrode pad, through the dome switch, to the electrically conductive material of the touch surface in both the released position and the depressed position.

    摘要: A bus architecture is disclosed that provides for transaction queue reallocation on the modules communicating using the bus. A module can implement a transaction request queue by virtue of digital electronic circuitry, e.g., hardware or software or a combination of both. Some bus clogging issues that affect conventional systems can be circumvented by combining an out of order system bus protocol that uses a transaction request replay mechanism. Modules can evict less urgent transactions from transaction request queues to make room to insert more urgent transactions. Master modules can dynamically update a quality of service (QoS) value for a transaction while the transaction is still pending.

    摘要: A touch sensing method is described as well as related methods and systems. In some embodiments of the touch sensing method, energy of a drive signal is allocated among frequencies of RF subcarriers such that the allocated energy meets electromagnetic emissions requirements for the application of a touch sensing system implementing the touch sensing method. Also described are methods of determining a spectrally shaped time domain digital waveform for use in generating a spectrally shaped drive signal.

    摘要: In certain embodiments, a method includes performing a first positive integration by sensing a first rising edge of a charging signal of a touch sensor during a first synchronization period and performing a first negative integration by sensing a first falling edge of the charging signal during a second synchronization period. The method also includes toggling the charging signal, resulting in a second rising edge of the charging signal during the second synchronization period. The method further includes performing a second negative integration by sensing a second falling edge of the charging signal during a third synchronization period and performing a second positive integration by sensing a third rising edge of the charging signal during a fourth synchronization period. The first integrations are associated with a first sample measurement and the second integrations are associated with a second sample measurement.

    摘要: A device includes a controller coupled to a touch sensor. The touch sensor includes a first array of capacitive nodes substantially aligned with a second array of capacitive nodes in a mechanical stack. The controller is configured, when in a self-capacitive mode of operation, to send a first drive signal to a plurality of the electrodes of the first array, send a shield signal to at least a portion of the electrodes of the second array at the same time as the first drive signal is sent to the plurality of electrodes of the first array, and sense touch inputs based on signals received from the plurality of electrodes of the first array while the first drive signal is being sent to the plurality of electrodes of the first array and the shield signal is being sent to the at least a portion of the electrodes of the second array.

    摘要: Systems, methods, circuits and computer-readable mediums for controlled secure code authentication are provided. In one aspect, a method performed by a host device includes transmitting a request to a client device, the request including a challenge for a property of a code stored within the client device, receiving a response to the request, the response comprising information associated with the property of the code, verifying correctness of the response based on the received information, and based on the verifying of the correctness of the response, determining that the code is an authorized code.

    摘要: In one embodiment, an apparatus includes a first electrode, one or more processors, and one or more memory units coupled to the one or more processors. The one or more memory units collectively store logic that is configured to cause the one or more processors to control connections of the first electrode by connecting the first electrode to a first reference voltage, then connecting the first electrode to a second reference voltage lower than the first reference voltage, and then connecting the first electrode to a third reference voltage lower than the first reference voltage and the second reference voltage. The second reference voltage is coupled to a capacitor.

    摘要: In one embodiment, a non-transitory computer-readable medium comprising logic is configured to, when executed by one or more processors, cause the one or more processors to perform operations comprising measuring samples from a touch sensor. Each sample is measured by determining, based on a first pattern of polarities, a polarity of a charging signal to be applied to an electrode of the touch sensor, the first pattern of polarities based on a signal associated with a noise source; applying the charging signal to the electrode, the charging signal, as applied, having the polarity determined based on the first pattern of polarities; and measuring a received signal from the touch sensor, the received signal resulting, at least in part, from the charging signal applied to the electrode. The operations comprise determining whether a touch event has occurred at the electrode by analyzing the received signals from the samples.

    摘要: In certain embodiments, an apparatus includes controller circuitry and a touch sensor that includes first electrodes. The controller circuitry is configured to measure first capacitance values during a first time period, each first capacitance value associated with a respective first electrode. The controller circuitry is also configured to determine a first hand-usage value based at least on a distribution of the first capacitance values. The controller circuitry is also configured to estimate a hand-usage state based at least on the first hand-usage value. The hand-usage state indicates one of the following hand configurations: right-handed interaction with the touch sensor, left-handed interaction with the touch sensor, or two-handed interaction with the touch sensor.
