  • Patent number: 8970535
    Abstract: Electronic apparatus (100) includes a display device (1), a detecting device (20) which detects an input, a state change detecting section (31), and a control section. The control section controls the detecting device (20) so that the detecting device (20) carries out the detection more times during a non-scanning period in a case where a state change causing an improvement in detection accuracy is detected and so that the detecting device (20) carries out the detection fewer times during the non-scanning period in a case where the state change causing a deterioration in detection accuracy is detected. With the configuration, it is possible to improve detection accuracy of the detecting device while reducing electric power consumption.

  • Patent number: 8928615
    Abstract: An oscilloscope with touch control has a touch screen display unit and a waveform processing and sampling unit. The touch screen display unit is connected to the waveform processing and sampling unit and has a touch control module and a display module. The touch control module detects a touch gesture and converts the touch gesture into a set of waveform processing parameters. The waveform processing and sampling unit has at least one signal input port to receive at least one external signal to be tested, processes the signal to be tested into a corresponding waveform image, and outputs the waveform image to the display module. Accordingly, the touch screen display unit enables the operation and display of the waveform thereon and provides more space originally occupied by conventional knobs so that the display module can be enlarged or the oscilloscope can be miniaturized.

  • Patent number: 8922516
    Abstract: A multi-points detecting method includes proving a touch panel including a plurality of detecting areas including a first detecting area, a second detecting area and a third detecting area. A maximum detecting value of a detecting curve is located in the first detecting area. The first detecting area and the second detecting area are analyzed to obtain a relative distance between a first touch point coordinate and a second touch point coordinate. The touch panel is defined as being touched at the first touch point coordinate or a middle point between the first touch point coordinate and the second touch point coordinate, when the relative distance is less than a predetermined distance. The touch panel is defined as being touched at the first touch point coordinate and the second touch point coordinate, when the relative distance is greater than or equal to the predetermined distance.

  • Patent number: 8917252
    Abstract: A conductive sheet, method for using conductive sheet and touch panel, having a base substance and conductive parts formed on one of the principal surfaces of the base substance. The conductive parts respectively extend in primary directions, and have two or more conductive patterns made from metal wires arranged in a second direction that is perpendicular to the first direction. The conductive pattern is constituted by serially connecting two or more large gratings in the first direction, and each of the large gratings is constituted by combining two or more small gratings. Around the edges of the large grating, non-connective patterns are formed from metal wires which are not connected with the large gratings.

  • Patent number: 8913040
    Abstract: A touch sensitive device having circuitry to compensate for crosstalk from the device display to the device touch sensor panel is disclosed. The crosstalk compensation circuitry can include a downsampler and a crosstalk compensator. The downsampler can downsample a display image to a manageable size for transmission and processing and can then send the downsampled image to the crosstalk compensator so as to provide information about the display operation that can be used to estimate the expected amount of crosstalk caused by the display. The crosstalk compensator can estimate the amount of crosstalk based on the downsampled image and can then compensate a touch image captured by the touch sensor panel for the estimated amount, the touch image being indicative of a touch or hover event at the panel.

  • Patent number: 8913014
    Abstract: An information processing apparatus for data input in which input and editing can be performed through a simple operation is disclosed. The apparatus includes first determination means for determining whether drawing has been completed following input of coordinate data in the drawing mode; second determination means which, if completion of drawing has been determined, is for adopting drawing data, which has been drawn from input of coordinate data until completion of drawing, as a drawing object to be edited, and determining whether this drawing object has a portion that overlaps another object; and control means which, if it has been determined that the drawing object to be edited has a portion that overlaps another object, is for applying control to the drawing object to be edited in such a manner that this drawing object will no longer have a portion that overlaps another object.
