摘要： An automated teller machine can use an array of pressure sensors, such as piezo-resistive sensors, to detect the presence of foreign objects, such as staples, paper clips, or rubber bands, in a stack of banknotes. A user can insert a stack of banknotes into an automated teller machine. A pair of opposing clamping surfaces can apply pressure to the stack of banknotes. An array of pressure sensors can sense non-uniformities in pressure over the area of the array. If circuitry coupled to the pressures sensors senses a presence of a high pressure area in the surface area of the banknotes, then the circuitry can generate a signal indicating that one or more foreign objects has been detected. The automated teller machine can then prompt the user to remove the stack of banknotes and remove the foreign object from the stack of banknotes.

摘要： A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.

摘要： An apparatus and method for classifying value documents includes least two sensor devices arranged to capture waves reflected on a front side and on a back side of a value document and to generate corresponding sensor data or to capture properties of the value document in at least two different regions of the value document by means of different measuring principles and to generate corresponding sensor data. At least one evaluation device is arranged to classify the value document with the aid of the sensor data generated by the at least two sensor devices, which sensor data relate to the waves reflected on the front side and back side of the value document or to the properties of the value document captured in the at least two different regions of the value document by means of different measuring principles.

摘要： A security document includes a non-homogeneous region formed e.g. by a structure of bars that vary the document's thickness dielectric permittivity or electrical conductance. The structure is verified by placing the document on the capacitive touchscreen of a verification device. Then, the user moves a finger or pen along the structure, which gives rise to a varying capacitive signal in the verification device. The signal can then be analyzed for deriving information about the document.

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： The present invention is a system and method to equip the ATM (Automated Teller Machine) with the special hardware to detect the each currency note to determine whether that note is a legal tender or not. The counterfeited currency hardware will work with computer executable instructions to detect counterfeited notes while feeding and dispensing in to and from the ATM machine respectively. The aim of the invention is to negligate the chance of counterfeited currency being fed and dispense from the ATM.
