  • Publication number: 20170199725
    Abstract: The speed of pen position detection is improved without increasing the circuit area and the current consumption. A sampling circuit samples a signal and outputs sampling data. A arithmetic circuit calculates a real part and an imaginary part of the sampling data. The arithmetic circuit classifies the real part of the sampling data into one of a plurality of groups and classifies the imaginary part of the sampling data into one of the groups according to an order of output of the sampling data from the sampling circuit. Then, the arithmetic circuit adds together real parts of sampling data belonging to a group and adds together imaginary parts of sampling data belonging to a group for each of the groups, and calculates amplitude and phase of the signal by using an addition result of the real parts and an addition result of the imaginary parts of each of the groups.

  • Publication number: 20140168130
    Abstract: An input method determining unit determines whether a hard button is short or long pressed, and an input switching control unit switches between modes. The input switching control unit determines that an operation mode is a touch operation one when the hard button is short pressed, and a touch-to-command converting unit converts an item corresponding to the short-pressed hard button into a command. The input switching control unit determines that the operation mode is a voice operation one when the hard button is long pressed, and a voice-to-command converting unit converts a voice recognition keyword which is voice-recognized into a command (item value). A state transition control unit generates an application execution command corresponding to the command, and an application executing unit executes an application.

  • Patent number: 8294910
    Abstract: An image scanner operates in a normal mode in which an image scanning process is executable; and a power saving mode in which less electric power is consumed than in the normal mode. The image scanner includes: a CPU for switching the image scanner between the normal mode and the power saving mode; an original size sensor circuit; and an FPGA connected to the CPU and the original size sensor circuit. In the normal mode, the CPU configures, in the FPGA, a normal-mode circuit needed for the image scanning process. When the image scanner transfers from the normal mode to the power saving mode, the CPU configures, in the FPGA, a power-saving-mode circuit for communicating with the original size sensor circuit, and stops the original size sensor circuit from operating. The power-saving-mode circuit is smaller in circuit size than the normal-mode circuit.
