    摘要: An electronic device samples radiofrequency signals measured by multiple antennas positioned across the digitizer, wherein the radiofrequency signals include noise components. The electronic device selects an orthogonal frequency outside the defined bandwidth of the working frequency and removes at least some of the noise components from the radiofrequency signals measured by each antenna based at least on a sense signal measured at the orthogonal frequency by the each antenna.

    摘要: A computing device is provided comprising a processor, a first display device having a first capacitive touch sensor, a second display device having a second capacitive touch sensor, and a hinge positioned between and coupled to each of the first display device and the second display device, the first display device and second display device being rotatable about the hinge and separated by a hinge angle. The processor is configured to detect the hinge angle at a first point in time, determine that the hinge angle at the first point in time is outside a first predetermined range, and upon at least determining that the hinge angle is outside the first predetermined range, perform run-time calibration of at least a plurality of rows of the capacitive touch sensor of the first display device and of the capacitive touch sensor of the second display device.

    摘要: Examples are disclosed that relate to interpreting user input at a computing device. One example provides a method comprising recording a plurality of interactions between a user and a computing device conducted using an input device, and extracting, from the plurality of interactions, one or more performance indicators. The method further comprises accessing a data store to obtain a predetermined profile that corresponds to the one or more performance indicators, the predetermined profile including one or more driver parameters, and implementing, at one or both of the computing device and the input device, at least one of the one or more driver parameters so as to at least affect how user input is interpreted at the computing device.

    摘要: A capacitive touch-sensor system comprises an electrode array coupled to an electromagnetic-noise source, a hardware interface, and associated output logic. The electrode array acquires sensory signal. The hardware interface exposes a touch-position output of the capacitive touch sensor. The output logic determines that an anomalous sensory electrode of the electrode array is proximate to a touchpoint, the anomalous sensory electrode providing an anomalous response to noise from the electromagnetic-noise source. Pursuant to determining that the anomalous sensory electrode is proximate to the touchpoint, the output logic identifies a non-anomalous sensory electrode of the electrode array which is usable to detect the noise. If an amplitude of the sensory signal from the non-anomalous sensory electrode exceeds a predetermined threshold, then the output logic invalidates the sensory signal for touchpoint resolution. If the sensory signal is not invalidated, the output logic computes the touch-position output based in part on the sensory signal.

    摘要: A base noise level of a touchscreen interface for a computing device is actively and adaptively calibrated. Antenna traces forming a digitizer of the touchscreen interface are allocated into antenna regions. Antenna regions with high energy signal levels and antenna regions with low energy signal levels are identified. Signal level information from high energy antenna regions is discarded. A noise level, caused by electrical components of the computing device, is determined within signals generated in the antenna traces based at least in part upon the low energy antenna regions. The digitizer is calibrated by reducing energy levels of signals carried by the antenna traces in all antenna regions by the noise level.

    摘要: A method for electronic device identifier assignment at a host computing device includes receiving a current local identifier of a separate electronic device and a full unique identifier of the separate electronic device. A host-specific identifier is assigned to the separate electronic device by, based at least in part on determining that the current local identifier of the separate electronic device is included in a set of local identifier values available for assignment, assigning the host-specific identifier to the separate electronic device with a same local identifier value as the current local identifier. Based at least in part on determining that the current local identifier of the separate electronic device is already assigned by the host computing device to a different separate electronic device, the host-specific local identifier is selected from the set of local identifier values available for assignment and assigned to the separate electronic device.
