  • Publication number: 20240160327
    Abstract: An RX electrode for a capacitive touch sensor including an electrode body, which includes first to fourth conductors, one of which includes a connecting portion. The first and second conductors are arrayed and located close to each other with a gap therebetween in a first direction, extend in a second direction. Application of external noise to the electrode body induces current flows in opposite directions through the first and second conductors, so that an electric field generated in the first conductor and an electric field generated in the second conductor offset each other. The third conductor, located on the one side in the second direction relative to the gap, connects first end portions of the first and second conductors. The fourth conductor, located on the other side in the second direction relative to the gap, connects second end portions of the first and second conductors.

  • Patent number: 9913084
    Abstract: A speech communication device includes microphones configured with: microphones M1 and M2 disposed at positions which are axisymmetric with a centerline in a width direction of a housing as a symmetric axis; and a microphone M3 disposed at a position which is on the centerline and closer to a speaker than the microphones M1 and M2 are. The speech communication device is further equipped with: a sound processor which includes: a beam former which is connected to the microphones M1 and M2 and forms a bidirectionality in which directionality is strong in two directions each perpendicular to the centerline and is weak in two directions each along the centerline; and an echo cancel unit which is connected to the beam former and the microphone M3 and removes a sound signal having been output from the microphone M3 from a sound signal having been output from the beam former.

  • Patent number: 6326564
    Abstract: The sensitive coordinate input device of the present invention adopts a system in which the finger F of the operator is regarded as one electrode, and the electrostatic capacitance is varied depending on the changes in the distances between the finger and another electrode which is separated therefrom via a dielectric. Four electrodes are preferably disposed at regular angular positions. Among the four electrodes, two electrodes, and two electrodes which are located at opposite positions are spaced at intervals, respectively. Across the four electrodes, a sensitive member 15 is laid. The surface of the sensitive member is to be touched with the operator's finger F. The sensitive member is preferably formed by a dielectric having a high dielectric constant, such as a ceramic plate. According to the present invention, the area of sensitive area can easily be increased, and the determination of the cursor position on the screen of the CRT display apparatus can readily be performed.
