摘要： A sensor includes a first element part having a first member and a first element. The first member is a acoustic tubular waveguide and extends along a first direction. The acoustic tubular waveguide includes a first opening and a second opening. A direction from the second opening toward the first opening is along the first direction. The first element includes a vibratile first membrane, and a first supporter supporting the first membrane. The second opening is between the first opening and the first membrane in the first direction. The sensor may be a Piezoelectric Micro electro mechanical systems Ultrasonic Transducer and may be used for inspecting paper and/or resin including detecting thickness of a fed through banknote and/or the presence of foreign matter thereon such as tape. An optical element may alternatively measure the vibration of a membrane from acoustic through transmission instead of an acoustic receiver.

摘要： Baseline values for metal detection readings associated with an item inserted into an infeed mouth of a depository are obtained before the item is pinched on a pathway of the depository. The baseline values are adjusted by additional readings obtained when the item is pinched on the pathway for transport. The adjusted baseline values are processed with calculated values from ongoing and fluctuating current readings to determine at least one final value. A determination is made as to whether the item includes at least some metal based on comparison of the at least one final value and a predefined value.

摘要： A method and device for non-contact detection of a thin medium (5) is disclosed. The device comprises a light source (1), an optical splitter (2), a reference plane (3), a linearly arrayed photoelectric detector (6), a signal processing module (4) and the thin medium (5). The method involves the following steps: acquiring time for targeted light which is emitted by the light source (1) and reflected by the thin medium (5) to the linearly arrayed photoelectric detector (6), and acquiring time for reference light which is emitted by the light source (1) and reflected by the reference plane (3) to the linearly arrayed photoelectric detector (6); according to the acquired time that the targeted light and the reference light arrive at the linearly arrayed photoelectric detector (6), computing a first optical path and a second optical path corresponding to the targeted light and the reference light respectively, and acquiring quantity of bright fringes and dark fringes of interference fringes according to a predetermined computing manner by the signal processing module (4); conducting difference comparison between the quantity of the bright fringes and dark fringes of the interference fringes and the quantity of the bright fringes and dark fringes of standard interference fringes according to the predetermined manner, and if the value of the comparison result is larger than the predetermined threshold value, determining that the foreign matters are positioned on the thin medium (5). The detection method and device solves the technical problems that precision is low and measuring wavelength is long caused by an existing mechanical thickness measuring device, an infrared detector and an ultrasonic detector used to detect the foreign substance on the surface of the thin medium.

摘要： In a bank-note processing machine, bank notes are guided through between two components of a checking device by means of a transport band. The transport band is led away at least partly from the checking device by means of deflection rollers to enable a better check of the bank notes and a trouble-free transport of the bank notes.

摘要： An apparatus and method for checking value documents, in particular bank notes, and a value document processing system having at least one sensor for capturing an electromagnetic radiation transmitted by a value document and generating corresponding transmission signals, and an evaluation device for checking whether the value document has a foreign object taking into account the transmission signals. From the transmission signals an edge course of the value document is derived and a rectangle is approximated to the edge course. By comparing the edge course of the transmission image with the rectangle, the presence of a foreign object such as an adhesive tape, can be ascertained.

摘要： An image sensor and a banknote processing apparatus are provided. The image sensor includes a first photosensitive assembly and a first light source assembly which is configured to irradiate light to an original, and further includes a first lens array configured to aggregate light reflected by the original to the first photosensitive assembly, and a light-entering surface of the first lens array is located in a transmission path of reflected light generated due to specular reflection occurred when light emitted from the first light source assembly irradiates on the original. According to different image grayscale values generated by the image sensor, the banknote processing apparatus judges whether a banknote surface is stuck to an adhesive tape.

摘要： Method and systems of automated document processing described herein include activating in sequence a plurality of illumination modules of an illumination source to illuminate a document, where the plurality of illumination modules are located at different positions relative to the document. The document can be imaged each time the document is illuminated by an illumination module to provide a plurality of images. A shadow profile of the document can be obtained based on the plurality of images. One or more of a boundary of the document and presence of a fastener attached to the document can be identified using the shadow profile. Any fasteners present may be removed using a robot arm.

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.
