  • Patent number: 11912331
    Abstract: A capacitance sensor (1) is provided with two electrode layers (10, 11) and an insulating layer (12) disposed between the electrode layers (10, 11). At least one of the two electrode layers (10, 11) is constituted by a reticulated soft electrode (50) that is formed from a conductive polymer and has a reticulated shape. The conductive polymer comprises a polymer and a conductive material dispersed in the polymer and has an elastic modulus of 1000 MPa or less. This method for manufacturing the capacitance sensor (1) in which the two electrode layers (10, 11) are constituted by the reticulated soft electrode (50) comprises: an electrode manufacturing step in which the reticulated soft electrode (50) is manufactured; and a laminating step in which the reticulated soft electrode (50) is laminated onto the front and back surfaces of the insulating layer (12).

  • Patent number: 7706292
    Abstract: A test packet generator of an entry device generates a delay test packet including priority information. A test packet transmitter of the entry device transmits the delay test packet to an exit device through a route corresponding to the priority information. A test packet receiver of the exit device receives the delay test packet. A reply packet transmitter of the exit device returns a reply-delay test packet toward the entry device through the same route in the counter direction. A reply packet receiver of the entry device receives the reply-delay test packet. A delay calculator of the entry device calculates a delay time on the basis of the time of transmitting the delay test packet and the time of receiving the reply-delay test packet. A route changer of the entry device changes routing appropriately on the basis of the delay time.
