Abstract: An automobile-simulation graphics display D is generated in sequential frames (1-7) in dependence upon positions and movements of driver controls 12, 14, 16, 18, signalled by transducers 22. Non-linear suspension and chassis models 26 and 28 operate in conjunction with a road model 34, to derive from the transducer outputs, representation of a current vehicle-position (including orientation). A prediction of vehicle-position five display-frames in the future is made from this representation by a chassis prediction model 36 using drive-train and steering and control extrapolations derived by units 30 and 32 from the transducer outputs. The five-frame lead compensates for delay in computing, processing data for generation of the image display, and display of the image (54, 56, 58).

Abstract: A system and method for upgrading a computer is disclosed. Certain essential chips present in the original computer system are functionally, but not necessarily physically, removed from the computer system. Functions which would otherwise be performed by the original chips are instead performed by higher-performance chips on a plug-in module which is plugged into the computer system. The functional removal of the certain chips from the original computer system is achieved through simple insertion of the plug-in module. No replacement or substitution of original chips or boards is necessary. Furthermore, upgraded computer systems may be further upgraded by replacement of a first plug-in module with a second plug-in module with different performance characteristics.

Abstract: The vessel portion of a gas-tight container suitable for packaging fresh foods is produced as a composite of paperboard and polymer film. A pair of folded paperboard blanks, pre-cut and pre-formed, are inserted into the opposite halves of split mold elements to a blow molding machine. Vacuum orifices in each mold half unit temporarily secure the position of a respective paperboard blank. The paperboard lined mold halves are closed upon a hot, extruded parison of malleable polymer leaving an end portion of the parison tube projecting from the closed mold unit. A fluid conducting needle penetrates this projected end portion to inflate the parison with an appropriate blowing gas. Such inflation expands the malleable polymer, seamlessly and creaselessly, into the internal corners and crevices of the folded paperboard blanks. Following chilling, the mold unit is opened and the pair of paperboard blanks are ejected as a singular unit, joined by a molded flange portion of the continuous polymer film. Finally, the two polymer coated paperboard vessels are separated by trimming about the flange.

Abstract: Circuitry and method for integrating current pulses, the circuitry including an integration amplifier having an integration capacitor located in its feedback loop. The current pulse integrator also includes three current sources and four current switches. A first current switch is located between a first current source and a second current source. A second current switch is located between the output of the integration amplifier and the second current source. A third current switch has one end connected to the first current source and the input to the integration amplifier, and the other end connected to the third current source. A fourth current switch is connected between the output of the integration amplifier and the third current source. Current passes through the integration capacitor in a first direction to charge the integration capacitor during a charge state of operation of the current pulse integrator. Current is prevented from passing through the integration capacitor in the first direction during at least one other state of operation of the current pulse integrator. An output current from the integration amplifier during the charge state of operation is substantially equal to an output current from the integration amplifier during the other state or states of operation.

Abstract: A method for generating an individual protection of a data carrier, for example a magnetic tape cassette, against unauthorised use in a data processing device is described. The protection prevents a data processing program contained on the data carrier being used or copied without authorisation. For this purpose, a device-specific identification, for example a device serial number, is preferably automatically scanned and stored in the device by the manufacturer. As soon as a data carrier is inserted for the first time into the device, the latter writes the identification onto the data carrier. From this time on, the data carrier can only be accessed by means of this device.

Abstract: A cache memory apparatus to be coupled to a main memory, comprises a cache memory having a plurality of ports and capable of being independently accessed through the plurality of ports. The cache memory stores a portion of data stored in the main memory and tag information indicating memory locations within the main memory of the data portion stored in the cache memory. A hit discriminator receives first tag information included in an address given when the cache memory is accessed and second tag information read from the cache memory in accordance with the given address, in order to discriminate a cache-hitting and a cache-missing on the basis of the first and second tag information. A replacement control circuit operates for replacing data and corresponding tag information in the cache memory when the cache-missing is discriminated by the hit discriminating circuit. A replacement limiting circuit operates for limiting the replacement of the cache memory to one time when a plurality of accesses to the same address are generated and all the plurality of accesses to the same address are missed.
