  • Method for detecting a type of charger coupled to an input-output circuit and input-output circuit therefor
    Patent number: 9484759
    Abstract: A power supply detection circuit detects power feeding to a VBUS terminal from the outside. A charger detection circuit detects the kind of charger by monitoring voltages of a DP terminal and a DM terminal. A control unit adjusts timing and instructs the charger detection circuit to start a charger kind detection process after a notification of detection of power feeding is received from the power supply detection circuit.

  • Input-output circuit
    Patent number: 9077195
    Abstract: A power supply detection circuit detects power feeding to a VBUS terminal from the outside. A charger detection circuit specifies the kind of charger by detecting the voltages of a DP terminal and a DM terminal. The charger detection circuit detects open, pull-up, pull-down of at least one of the DP terminal and the DM terminal or formation of a short circuit between both the terminals.

  • Image data processing apparatus having pixel quantity conversion and error diffusion functions
    Patent number: 6016370
    Abstract: An image data processing apparatus is described that prevents the quality of image data from being degraded by pixel quantity conversion. The apparatus includes an analog processor, a quantity converter and a binarization converter. The analog processor quantizes each of the analog element data to generate multiple-state element data, The quantity converter changes the number of plural pieces of multiple-state element data in one line to generate quantity-converted element data. The quantity converter averages at least two adjacent pieces of multiple-state element data to generate an average value as one piece of new multiple-state element data. The quantity converter further selectively outputs the new multiple-state element data and original multiple-state element data as the quantity-converted element data. The binarization converter binarizes the quantity-converted element data to generate binary element data.
