Abstract: A device to operate a microprocessor (10) is proposed, which contains a control circuit (11) for the presetting of an active and an inactive operating condition of the microprocessor (10). The microprocessor (10) can be offset into the inactive condition via an internal or via an external switching-off signal (16, 17). Waking-up the microprocessor (10) can be undertaken via an internal wake-up signal (13), which is emitted by a watchdog (12), or via an external wake-up signal (15) which is emitted by an oscillator (14). The periodic occurrence of the wake-up signal (15) emitted from the oscillator (14) enables a waking-up of the microprocessor even when the inactive operating condition has been caused because of interference occurring or when interference occurs during the inactive condition. The device according to the invention is particularly suitable for use in an environment which is contaminated with electromagnetic fields and with interference signals. <IMAGE>

Abstract: To record a multi-valued image by an ink-jet head, an ink droplet is jetted from a recording element (nozzle) for the number of times corresponding to the density of a pixel to be reproduced. Accordingly, the pixel data to determine the number of ink-jet operation is expressed by a plurality of bits and the data of each bit are transferred to a plurality of shift registers at a time. Each shift register has storage capacity based on bit data corresponding to the number of recording elements of a recording head. When data transfer is completed, a driving signal is supplied to the recording head. The driving signals are counted and each recording element is driven based on the count result and the data stored in each register.

Abstract: The invention relates to an eccentricity correction procedure for pneumatic tyres, preferably tubeless tyres having radial carcasses for cars having 5 DEG  rims, each tyre initially being mounted on a master rim which, apart from its particularly high precision, corresponds to the production rims envisaged for the relevant tyre, the tyre is subsequently inflated to an air pressure in the range from -0.3 bar to +0.2 bar about the envisaged maximum operating air pressure, after which the wheel, essentially consisting of master rim and tyre to be corrected, is pressed against a measuring device, for example against a drum-shaped force measuring device, and at least one radial variable is measured and - preferably electronically - is recorded as a function of the wheel angle of rotation which runs through the complete interval from 0 DEG  to 360 DEG , the minimum and the maximum are then determined, the difference between the two extremes, that is to say the maximum force or radius fluctuation, is subsequently determined, is then compared with the tolerance value to be permitted, after which the tyres whose maximum fluctuation lies above the permitted tolerance value are subjected to a correction in the bead area. In order to make a correction possible without additional components and without a local reduction of the profile depth, it is proposed that at those points where the local radial force or the local tyre radius is greater than the minimum plus the maximum tolerance, at least sufficient material is removed from the radially inwardly pointing seating surface of the tyre bead that subsequently the remaining fluctuations lie within the tolerance band. <IMAGE>

IPC: G06F21/24

Abstract: The disclosed methodology permits an insecure computing system to safely perform high security electronic financial transactions. The present invention permits the hash of a file to be taken on an incremental basis. It permits any part of the file to be changed while allowing a new aggregate hash to be computed based on the revised file portion and the prior total hash. The aggregate hash is readily updatable with each record revision without having to recompute the hash of the entire file in accordance with conventional techniques. These objectives using two functions. The first function is an effective one-way hash function "H" for which it is computationally impossible to find two data values that hash to the same result. The second function is a commutative and associative function "F" (and inverse "Finv") and provides a mechanism for combining the aggregate hash and the hash of updated records. Examples of these latter functions include exclusive OR ("XOR"), and arithmetic addition. The methodology involves combining the hash of each file record and the hash of an identification of the record (i.e., a record number or key). These hashes are combined using a function ("F") whereby individual records may be extracted using the inverse of that function (Finv). In this fashion, an individual record may be extracted from the aggregate hash and updated. With each update, the file hash as computed according to this invention is preferably also written after being encrypted under a key known only to the valid user, or if it is digitally signed by the valid user or if it is held in a tamper resistant storage. Each record is represented by its identification hashed together with its data content. All such record are added together to provide a highly secure integrity check. This aggregate hash reflects the entire database such that the tampering (or rearranging) of any data record is revealed by the use of the record identifier (i.e., record number) in the hash calculation due to its impact on the aggregate hash (e.g., the sum).
