Abstract: A computer includes a main processing unit having arithmetic logic, memory address control, input/output address control, and execution control. The computer also has an operating system program which includes an interrupt handler module. A variable frequency clock oscillator is disclosed which is controlled by the operating system via the execution control unit of the main processing unit. Machine level instructions in the executing program change the clock speed whenever it is necessary to keep the computer in synchronism with one of its I/O adapters or to speed up the clock when slow speed circuits are not being utilized. Clock speed is changed by the interrupt handling module. Circuits and programs, which require longer cycle times to execute properly, are placed together on interrupt levels. For example, the machine check program requiring the slowest clock speed is assigned to interrupt level 0. I/O adapters using low-speed circuitry are assigned to interrupt levels 1, 2 and 3.

Abstract: An improved security system is disclosed which uses an IC card to enhance the security functions involving component authentication, user verification, user authorization and access control, protection of message secrecy and integrity, management of cryptographic keys, and auditability. Both the security method and the apparatus for embodying these functions across a total system or network using a common cryptographic architecture are disclosed. Authorization to perform these functions in the various security component device nodes in the network can be distributed to the various nodes at which they will be executed in order to personalize the use of the components.

Abstract: Apparatus and methods are described which take advantage of the peculiar characteristics of dynamic signature data while segmenting and compressing such data for storage on a limited capacity device. Compression is accomplished by digital oversampling, segmenting, filtering, decimating and later interpolating reference signature data, thereby allowing storage in compressed form without significant matching degradation. The pen down and pen up information which define signature segments is separated from the pressure waveform and stored in a separate array for each reference signature. The acceleration and pressure data are then filtered, decimated and stored for each reference signature. Later, during identity verification, the stored acceleration and pressure data are restored to an oversampled rate by interpolation. To verify the identity of a person supplying a trial signature, each segment of the trial signature is compared with corresponding segments of one or more of the stored reference signatures.

Abstract: A teller machine for drive up applications is disclosed. The machine has a safe with an access slot. The machine also has a user panel which has an opening that lies transverse to the slot. A document carrier is described which rotates documents around two different axes as it carries them between the slot and the opening to allow passage of the documents through both.

Abstract: A user guidance display system provides an animated display of example action being entered into a displayed image of the machine, to show a self-service machine user how the machine is to be operated. The various graphic images which show the prospective user what to do are created on a personal computer, using any of the commercially available graphic design programs. The binary file provided by the design program is processed, to compress the file into a special form having reduced memory requirements and having synergism with the image-displaying apparatus so as to permit fast and low overhead display of each image. By displaying a base image comprised of a number of image fragments, the base image can be changed during the course of guiding a user through a transaction. Animation is provided by sequentially displaying a plurality of image fragments under control of an animation list which, in turn, controls a timer.

Abstract: Visualizable and descriptive data handling system including an assembly comprising a unit for reading a video disk on which images of schematic detailed layouts that can be displayed on a unit screen are recorded. A double entry table, T.sub.xy in memory correlates each of the image divisions of coordinates x.sub.i Y.sub.i with a memory location which itself contains the memory location address from which the descriptive data relative to the image element occupying the square, are stored. For every image, a table T.sub.REF of descriptive data is built through data input means, the memory address, where begin each of the descriptive data for a given image element, being recorded in table T.sub.xy at the address correlated with x.sub.i y.sub.j. When pointing a light pen on to the screen, the coordinates of the selected point are sent from a mini-computer which causes the descriptive data corresponding to the selected element, to be displayed upon look-up of the tables corresponding to the display image.

Abstract: A self service terminal for a lodging facility includes room key dispensing and receiving. The present invention allows a guest to automatically check into a lodging facility, have an appropriate room assigned to him in accordance with his request and obtain a key for a room without the intervention of employees of the lodging facility. The invention also includes an apparatus and method for allowing a guest of a lodging facility to check out at the self service terminal upon departure intervention by employees of the lodging facility, with the self service terminal recovering the room key which the guest had been using.

Abstract: A lockable enclosure is disclosed which may be installed at locations accessible to customers for vending merchandise, dispensing money or receiving deposits, and where a potential attacker would have only a limited period of time to break into the enclosure before the police or security personnel would be able to arrive and intervene against the attacker. The latches and latch bolts of the enclosure have apertures or projections which interlock with mating projections or apertures upon deformation of the sheet metal door or the sheet metal walls of the enclosure when an attacker deforms the enclosure sufficiently to cause damage to the lock or latches. Such interlocking prevents retraction of the latches or latch bolts holding the door closed even if the lock mechanism is completely destroyed or removed by force.

Abstract: A banking machine having a single opening for both envelope and individual check or note deposit is disclosed. The entrance to the depository has a deposit item thickness sensor just inside of the deposit gate opening which can detect the difference between a thicker envelope deposit item and a thinner single sheet of paper. A computer is responsive to signals from the thickness sensor to control a deflector which permits envelopes to pass directly through to a sequential stacking deposit bin. Alternately, the thickness sensor causes the computer to control the deflector to divert a single sheet of paper into a read leg of the bifurcated transport. After entering the read path, document alignment rolls placed at a slight angle to the direction of document travel tend to move the document toward a registration edge before the document passes the read head.

Abstract: A scanner for scanning an increased area of a finger held or pressed on a concave elliptically cylindrical surface having two focal axes includes a linear light source positioned at one focal axis of a first reflective cylindrical elliptical surface, the other focal axis coinciding with one focal axis of the concave elliptical surface in contact with the finger. A second reflective, cylindrical elliptical surface has two focal axes where one of the axes coincides with the position of a linear array combination of photosensitive elements and charged coupled devices and the other coincides with the other focal axis of the concave elliptical surface in contact with the finger.

Abstract: A money feeding machine having a friction feed mounted to feed from the top of a stack of money is disclosed. The stack of money is contained within a cassette having a moveable bottom. The bottom of the cassette is raised by a motor as money is fed from the top of the stack in order to maintain the top of the stack of money substantially at the top of the cassette and available for feeding by the friction feed. Ramps are mounted a predetermined distance down from the top of the cassette to squeeze sheets of money inwardly and cause them to bow upwardly as they are pushed up by the motor. The ramps cause blocks of mint money to be separated into a short loose stack of sheets above the ramps for reliable feeding by the friction feed.
