    摘要: A method for verifying an object preferably a document, a (bank) card and/or a product package is provided with an electrically conductive security feature on a device with a capacitive surface sensor. After the object with the security feature is placed on the surface sensor, in particular a dynamic input is performed on the object and the electrically conductive security feature using an input means for generating a characteristic time-dependent signal on the surface sensor. The detected time-dependent signal is subsequently evaluated. Furthermore, an object with a security feature or method for its production, system or kit for carrying out the method and for verifying a document is provided with a conductive electrical security feature on a capacitive surface sensor.

    摘要: An electrostatic capacitance detection device includes a first electrode, and a second electrode at least a part of which is opposed to the first electrode across a transport path extending in a transport direction in which a detection target having a sheet shape is transported. The first electrode and the second electrode extend in a cross direction intersecting the transport direction and have mutually different shapes. Alternatively, the electrostatic capacitance detection device further includes a first floating electrode disposed on the side of the first electrode opposite to the transport path, and a second floating electrode disposed on the side of the second electrode opposite to the transport path. Alternatively, at least one of the first electrode or the second electrode is provided with a first electric field adjuster or a second electric field adjuster.

    摘要: A device for detecting a foreign object attached on a surface of a sheet-like medium, comprising a static electricity providing part (A) for providing static electrical charges, a medium transporting part (B) for transporting a medium under detection, and a static electricity sensor and identifier part (C). The medium transporting part comprises a static electricity receiving unit and a static electricity absorbing unit sequentially connected. The static electricity receiving unit is connected to the static electricity providing part (A), and the static electricity absorbing unit is connected to the static electricity sensor and identifier part (C). The static electricity receiving unit is configured to transfer the static electrical charges obtained from the static electricity providing part (A) to the medium under detection. The static electricity absorbing unit is configured to absorb the static electrical charges of the medium under detection.

    摘要: The flat mount assembly, or transponder, has at least one semiconductor chip that is connected to an antenna for interchanging data and power with an electronic apparatus. The antenna is formed of two electrical conductors. A conductive layer is formed on the mount in overlapping relationship with the electrical conductors of the antenna. The overlapping conductive layer results in greater capacitive coupling between the electronic apparatus and the flat mount assembly.
