A handwriting recognition device comprises a transducer surface responsive to a pen positioned thereon for representing the coordinate position of the pen as an electrical signal, and data processing means for recognizing a handwriting effected with the pen, the data processing means including a microprocessor based control controlling a read/write memory, a non-volatile read-only memory storing a handwriting recognition routine to store recognized handwriting in the read/write memory, and an in...

The invention relates to an information board comprising a rectangular base plate having vertical first and second lateral supports; a number of flat, rectangular first and second sign elements arranged in a plane parallel to the base plate, each of said sign elements being provided with at least one groove extending in the plane of the sign element to retain an exchangeable strip provided with characters, of the same length as the sign element and slightly narrower than the groove, said strip b...

Each semiconductor chip included in an information card according to this invention is enclosed in a metallic casing and roofed by a cover film. A conductor strip, extending from each of contacts of the semiconductor chip, is attached to the metallic casing through an insulative material. An electrically conductive elastic member having a magnet at its free end is provided in the metallic casing at a location corresponding to the conductor strip. When the conductor strip is not in contact with i...

An information processor for rendering input data compatible with standard video recording and/or display equipment, comprising means for digitizing the input data over periods which are synchronous with the fields of a standard video signal, a store adapted to store the digitized data and release stored digitized data in correspondence with the line scan of a standard video monitor, the store having two halves which correspond to the interlaced fields of a standard video signal and being so arr...

Method and apparatus for transferring encoded information from one or a first identification device to another or second identification device, the apparatus having relatively displaceable jaws actuated by oppositely extending handles, the lower jaw receiving and securely holding the first identification device in exposed relation to the upper jaw, and the upper jaw receiving and securely holding the second identification device, a plurality of punch pins being carried by and selectively displac...

An information system includes an information carrier and a reading unit. The information carrier includes an inner and an outer layer, the outer layer constituting a protective casing surrounding the inner layer and hiding the information. The inner part is formed of at least one electrically conducting closed loop in which an electrical current is intended to be induced, this loop having a plurality of openings therein in the same plane. These openings are so positioned that at least two paral...

An electrical signal transmission system, applicable to the transmission of signals from trackside hot box detector equipment for railroad locomotives and rolling stock, wherein a basic pulse train is transmitted whereof the pulses are of a selected first amplitude and represent a train axle count, and a spike pulse of greater selected amplitude is transmitted, occurring immediately after the axle count pulse to which it relates, whenever an overheated axle box is detected. To enable the signal ...

An information recorder is provided with a rotatable drive shaft for moving linkage means including a marking member to record the different speeds of drive shaft rotation on a movable chart in said recorder, and an adjustable member is adjustably driven by a manual adjusting member toward a preselected position to predeterminately space a contact thereon connected in an electrical warning circuit from a cooperating contact on said linkage means to thereby define the speed of drive shaft rotatio...

An information card of the magnetic-type in which card information is magnetically recorded. The card comprises a base sheet made of a thermoplastic material having a desired rectangular shape and a thickness enough to give the card required mechanical strength, and a magnetic sheet consisting of a support layer of the same thermoplastic material as the material of the card base and a magnetizable layer formed on one surface of the support layer. The magnetizable layer may be covered with a prot...

An information card for credit and accounting system having a monolithic or solid state memory for storage of information responsive to computer controlled systems.
