摘要： A technique for performing partial reads of a touch sensor (10) provides several advantages, including scalability to touch sensors with high sensing-line counts, and reductions in operating power. The technique involves identifying a region (46) of the touch surface (12) of the touch sensor (10) to be read and performing a partial read directed to the identified region. Rather than exciting all sensing lines of the touch surface (12), the partial read excites one or more of the sensing lines (18, 28) that are involved with the identified region (46), without exciting one or more of the uninvolved sensing lines (18, 28). Identifying the region or regions (46) to be read involves, for example, obtaining touch-control information from a software application (74) running on a host device (72) that includes the touch sensor (10).

摘要： A technique for reading the columns and rows of a touch sensor provides several advantages, including scalability to touch sensors with high column/row counts. Reading the touch sensor relies on combining the row or column outputs of the touch sensor, during column and/or row excitation of the touch sensor, with the resulting combined signal or signals transformed into the frequency domain and touch detection based on evaluation of the frequency-domain values corresponding to the excitation frequencies.

摘要： A technique for reading the columns (12) and rows (14) of a touch sensor (10) provides several advantages, including scalability to touch sensors with high column/row counts. A simultaneously applied set of column input signals (24) yields a corresponding set of column output signals (34) that are combined into a combined column signal (38) that is transformed into the frequency domain after digitization, to yield column values (48) corresponding to the respective touch sensor columns (12). The same process applied with respect to the touch sensor rows (14) yields a set of row values (50), with evaluation of the frequency-domain column and row values (48, 50) providing the basis for detecting touch inputs to the touch sensor (10).

摘要： A method is disclosed—for a wireless communication device served by a network access node—of keeping a time reference at the wireless communication device. The wireless communication device is configured for operation according to at least first and second operational modes, the second operational mode having lower power consumption than the first operational mode. The method comprises (during operation according to the first operational mode) determining (for the second operational mode) desired timings of timing signals to be transmitted from the network access node, and transmitting a request signal to the network access node, wherein the request signal carries information of the desired timings of timing signals to be transmitted from the network access node. In some embodiments, the method further comprises receiving a response signal from the network access node, wherein the response signal carries information of actual timings of timing signals to be transmitted from the network access node. Corresponding method for a network access node, apparatuses, wireless communication device, network access node and computer program product are also disclosed.
