  • Patent number: 10345974
    Abstract: A setting unit sets, if any measurement result of peripheral electrodes exceeds a threshold value, an accumulation number of each mutual-capacitance of intersection points, so that the accumulation number of an intersection point closer to a position of a conductor object is larger, and the accumulation number of an intersection point farther from the position of the conductor object is smaller. A setting unit sets, if all of the measurement results do not exceed the threshold value, the accumulation numbers of intersection points to be the same value.
    Type: Grant
    Filed: October 13, 2016
    Date of Patent: July 9, 2019

  • Patent number: 9778806
    Abstract: Provided is a touch detection device, including: a determining unit configured to determine a region of a conductive object based on measurement of a self-capacitance of each of a plurality of electrodes arranged to intersect with each other; and a detecting unit configured to detect the conductive object based on measurement of a mutual capacitance of, among the plurality of electrodes, an electrode corresponding to the region of the conductive object determined by the determining unit, without measuring a mutual capacitance of an electrode outside of the region of the conductive object determined by the determining unit.

  • Patent number: 7786703
    Abstract: An electronic device which is capable of performing high-accuracy remaining battery capacity management. The electronic device has a plurality of battery pack compartments assigned specific addresses, respectively. A remaining capacity-detecting unit detects the remaining battery capacity of a battery pack mounted in a battery pack compartment. A control microcomputer receives information indicative of a remaining battery capacity sent from a battery pack accommodated in one of the battery pack compartments and address information on the battery pack compartment, and sends correction information concerning the remaining battery capacity to the battery pack.
