A capacitive touch sensor is disclosed for use with input signal. The capacitive touch sensor includes a number n of input/output lines. Each of the number n of input/output lines is electrically disconnected from every other of the number n of input/output lines. Each of the number n of input/output lines is arranged to cross every other of the number n of input/output lines. Each of a number &#x3b2; of positions includes one of the number n of input/output lines crossing another of the number n of input/output lines.

Capacitive touch sensor and method

A device and algorithm for allowing a customer to choose a photo book cover template that is compatible with a photo having faces. The photo is compared with a set of templates arranged in a first order to determine how compatible the photo is to each of the templates, and a score indicative of compatibility is assigned. A re-sorted set of compatible templates combined with the photo is presented to the customer for consideration.

Digital to analog converters have first and second to analog arrays. The first digital to analog array has a reference input, a reference output, a first digital input that is connectable to a digital signal, and an analog output. The second digital to analog array includes a reference input, a reference output that is coupled to the reference input of the first digital to analog array, a plurality of switches coupled to the reference input, and a plurality of resistors coupled between the switches and the reference output.

Digital to analog converter

Methods, apparatus and articles of manufacture (e.g., physical storage media) to calibrate interpolating string digital-to-analog converters are disclosed. Example methods disclosed herein to calibrate a digital-to-analog converter (DAC) include determining a first calibration codeword based on a first nonlinearity error value measured at an output of the DAC when a most-significant-bit (MSB) portion of an input codeword is applied to an input of the DAC. Such disclosed example methods also include determining a second calibration codeword based on a second measured nonlinearity error value measured at the output of the DAC when a least-significant-bit (LSB) portion of the input codeword is applied to the input of the DAC. Such disclosed example methods further include combining the first calibration codeword and the second calibration codeword to determine a third calibration codeword to be accessed by the DAC to calibrate the output of the DAC when the input codeword is applied to the DAC.

Calibration of interpolating string digital-to-analog converters

A touch sensor apparatus includes a grid of intersecting sensor lines, a plurality of input/output (IO) pins, a plurality of diodes, a processor coupled to the IO pins. More specifically, each intersection includes a capacitor coupling together the intersecting sensor lines. Each diode is coupled to a corresponding IO pin, wherein each IO pin couples through its corresponding diode to a channel of intersection points of the sensor lines and, without the diode, each IO pin couples to a different channel of intersecting points of the sensor lines. The processor is configured to sequentially provide a transmit signal through each IO pin while detecting a response signal on the other IO pins.

Capacitive touch sensing

A liquid crystal display (LCD) that includes a plurality of segments, and a plurality of control lines to activate the plurality of segments. Each of the plurality of segments is associated with an intersection of two of the control lines, and each of the plurality of control lines intersects with each of the other plurality of control lines.
