摘要： A capacitive touch sensor of the type employing adjacent drive and sense electrodes, in which an additional sense electrode Yl is provided as well as the conventional drive electrode Xn and sense electrode YO. The drive and two sense electrodes are arranged on the bottom side of a dielectric panel, the top side providing- a sensing surface to be touched by a user's finger or a stylus. The additional sense electrode is positioned on the underside of the dielectric panel so that it is shielded from the drive electrode by the conventional sense electrode. As a consequence, the conventional sense electrode is much more sensitive to the proximity of the finger or stylus than the additional sense electrode which primarily registers noise. The signal collected from the additional sense electrode is then subtracted from the signal collected from the conventional sense electrode, thereby to cancel noise. Another design provides similar functionality with a capacitive touch sensor of the type employing single-ended electrodes.

摘要： A sensor is arranged to determine the presence of an object from a change in a capacitance of a sensing element. The sensor comprises a capacitance measurement circuit operable to perform measurement cycles to measure a capacitance of the sensing element, and a controller circuit. The control circuit is operable to detect a periodic noise signal induced on-the sensing element, to determine a first part, of a repeating pattern of the periodic noise signal, which causes a change in an amount of charge present on the sensing element, which affects the measurement of the capacitance of the sensing element by the capacitance measurement circuit, to determine.a second part of the repeating pattern of the periodic noise signal, which does not cause a change in the amount of charge present on the sensing element, and to control the measurement cycles of the capacitance measurement circuit to perform the measurement cycles during the second part of the periodic noise signal and not to perform the measurement cycles during the first part of the periodic noise signal. The sensor is therefore arranged to detect a synchronous pattern of the noise signal induced. on the key, during a noise sensing phase, and to synchronise the generation of a plurality of measurement cycles within the bursts to reduce the effeets of the noise signal on the measurement of the change in the capacitance of the sensing element. The sensor can be used, for example, to form a two dimensional touch sensor, which can be overlaid on a liquid crystal display (LCD) screen. As such, the effects of noise on the detection of an object, caused by a noise source such as common voltage signal of the LCD screen can be reduced.

摘要： Noise reduction in a one- or two-dimensional capacitive sensor array is achieved by rejecting and re-acquiring noisy signals. The sensor array is formed of crossed X and Y lines for drive and sense functions respectively, each of the X lines being driven in turn to acquire a full frame of data from the sensor array. A controller actuates the X lines in turn and, for each X line, charge is transferred to charge measurement capacitors connected to respective ones of the Y lines. The controller measures a signal value from a first one of the measurement capacitors, and then tests if that Y signal value has a magnitude lying within an acceptable range. If not, the measurement capacitors are all reset without their signal values being measured, and the controller re-drives the same X line to initiate another charge transfer into the measurement capacitors for that X line. It is then attempted once again to acquire Y signal values for that X line. Noisy signal values are thus rejected, and the sensor re-acquires substitute signal values. This is distinct from the approach of acquiring data and then reprocessing it to remove or suppress noisy data as in the prior art.

摘要： A capacitive position sensor for detecting the position of an object, typically an operator's finger (105), relative to a resistive sensing element (207), wherein the sensing element comprises a sensing path that has terminals (201, 202, 203) connected along it that subdivide the sensing path into multiple sections (204, 205, 206). Each terminal (201, 202, 203) is coupled to its own sensing channel (301-305), each of which generates a signal that is sensitive to the capacitance between its terminal and a system ground (107). The signals are fed to a processor for analysis. The processor determines over which section the object is positioned by comparing the signals from the sensing channels, and determines the position of the object within that section by comparing the signals from the terminals spanning that section. In this way, the sensing path can be formed in a closed loop, such as a circle for a scroll dial, in which the operator's finger position and movement can be uniquely determined in a straightforward manner.

摘要： A carrier and an apparatus for use with the carrier (101). The carrier (101) contains one or more substances in a layer (105) formed on a substrate (103) which are retained bound to the carrier (101) in ambient conditions, but cause emission of a trace gas when locally irradiated with a beam (115) from an electromagnetic radiation source (111) that is part of the apparatus. The beam (115) transforms the substance locally to cause the trace gas to be emitted in a plume (117). The apparatus scans the beam (115) along a set path over the carrier (101) to controllably release amounts of the trace gas. The apparatus includes a flow generator that causes a transport gas (121) to flow past the carrier (101) so that when the trace gas is emitted it is conveyed away mixed in the transport gas.

摘要： A touch sensor senses the presence of an object at one of a plurality of channels on a surface of the touch sensor, wherein proximity of the object to the touch sensor results in a change in capacitance at the position of the channel. The touch sensor includes a drive circuit and a charge sensing circuit, each coupled to each of the channels. The charge sensing circuit includes at least one charge measurement capacitor. A measurement cycle is applied to the touch sensor having a drive portion and a sense portion. During the drive portion a charge is applied to the channels and therefore the charge measurement capacitors of the touch sensor, and during a sense portion the charge measurement capacitors are discharged by a predetermined amount and the remaining charge on the charge measurement capacitors is measured.

摘要： An iterative method for generating a series of output signal values from a series of input signal values is described. Iterations of the method comprise the steps of obtaining a current input signal value for the current iteration, comparing the current input signal value with an output signal value determined in a previous iteration, updating a counter value determined in the previous iteration based on the result of the comparison between the current input signal value and the previous output signal value such that the updated counter value replaces the counter value determined in the previous iteration, determining a slew value based on the counter value; and adding the slew value to the previously determined output signal value to generate a new current output signal value. Thus different slew values may be added to the previous output signal to obtain a new output signal. The counter value is updated so that its value reflects recent trends in the input signals. E.g. if the input signal is on an upward trend, the counter value may achieve a relative high value, for example because it is incremented each time an input signal exceeds a previously determined output signal. The magnitude of the slew values may increase as the counter value increases, thereby allowing the output signals to more rapidly track changes in the input signals.

摘要： A capacitive touch sensor is provided having sensing path for setting a color parameter to a desired value within a range, the color parameter being color hue, color saturation or color temperature. The sensor has a first mode of operation in which a parameter can be set approximately to a desired value and a second mode in which the value can be refined to the exact amount. In the first mode, the full range of possible values is mapped onto the sensing path and a user touch selects a value within the full range according to its position along the sensing path. In the second mode a finer adjustment is provided for, either by mapping a narrower sub-range of the full range onto the sensing path, or by allowing incremental adjustment of the parameter from the value initially set in the first mode, each incremental unit of adjustment being triggered by the object being displaced through a predetermined threshold displacement along the sensing path. Switching from the first mode to the second mode is triggered if moving displacement of the object along the sensing path from the first point of touch exceeds a minimum threshold value. This provides an intuitive transition for the user from coarse to fine adjustment.

摘要： In a capacitive sensor of the type having X electrodes which are driven and Y electrodes that are used as sense channels connected to charge measurement capacitors, signal measurements are made conventionally by driving the X electrodes to transfer successive packets of charge to the charge measurement capacitors. However, an additional noise measurement is made by emulating or mimicking the signal measurement, but without driving the X electrodes. The packets of charge transferred to the charge accumulation capacitor are then indicative of noise induced on the XY sensing nodes. These noise measurements can be used to configure post-processing of the signal measurements.
