Abstract: A method of and apparatus for starting and accelerating a vehicle through a range of vehicle speeds during which the vehicle internal combustion engine is operated in a plurality of different operating modes is disclosed. The engine may first be cranked in a compressionless mode preparatory to starting and then run in a second mode at a relatively low speed for a warm-up interval as a six-stroke cycle engine where each engine cylinder cycle includes an essentially adiabatic compression and expansion. The system may then convert to a third mode of operation as a four-stroke cycle engine during normal engine operation. Different operating modes are available during this normal operation. Under high demand conditions, the engine may be run as a conventional inefficient but effective throttled engine or converted to operation in a fourth mode as a two-stroke cycle engine. The vehicle management system includes a first read only memory for storing a fixed table of engine operating parameters corresponding to various engine conditions, and a random access second storage means for storing a table of engine operating parameters corresponding to various engine conditions with the second table being initially the same as the first table. The system responds to sensed engine conditions to modify the parameters in the second table and controls the vehicle in accordance with the parameters stored in the second table. Both short term modification to accommodate dynamic changes in the sensed engine conditions and long term modification to compensate for relatively slow changes in the engine and the management system are made to the information in the random access memory. The modifications may be on an overall engine basis or an individual cylinder basis.

Abstract: A pattern recognition apparatus has a contour segmentation unit (14) for dividing an input pattern into segments, a characteristic extraction unit (16) for extracting characteristics of the input segments, and a reference unit (20) for storing characteristic data of reference patterns. The reference unit (20) includes a main reference (22) and a detailed matching reference (26). The main reference (22) stores partial pattern characteristic data representing the characteristics of segments of each reference pattern. The detailed matching reference (26) stores detailed characteristic data of each reference pattern together with a program for specifying an operation procedures thereof. A matching processor (18) sequentially compares and colla­tes the input pattern with the reference patterns to find out that standard pattern with which the input pat­tern is matched with the highest similarity. When the input pattern is matched with several reference pat­terns, a detailed recognition unit (24) performs a detailed recognition process using the detailed charac­teristic data of these reference patterns to finally select the correct one from among the reference pat­terns. The main reference (22) additionally stores identification marks to identify specific reference segments necessary to acquired the above detailed characteristic data.

Abstract: A thrombectomy catheter for enlarging the average cross-section of arteries constricted by arteriosclerosis comprises a tube (1) with a tool (2, 2', 2", 2"') located rotatably on the front, such as a reamer. The tool has a central recess (4, 4', 4", 4"'). The thrombectomy catheter is pushed along a guide tube (3, 12, 13, 16) specifically inserted into the artery. The cross-section of the guide tube differs from the circular shape, and the recess in the tool is made to fit the cross-section of the guide tube for transferring torque while maintaining the axial displaceability. The guide tube can also consist of several single wires or wire combinations and have an enveloping overall cross-section which differs from the circular shape. It is also possible to provide an additional parallel wire in the interior of the tube, which engages with the tool. The guide tube lying inside the thrombectomy catheter assumes where appropriate together with the additional wire the function of a flexible drive shaft. For this purpose it is connected via a driver (5, 11, 1', 11") to an electrical drive motor (6). <IMAGE>

Abstract: The object is effectively to prevent with the least possible outlay the occurrence of pattern windings during the winding of cross-wound bobbins. …<??>According to the invention, the particular cross-wound bobbin is accelerated and decelerated solely by the driving drum. The driving drum is so accelerated and braked by its drive according to a predeterminable periodic function that the cross-wound bobbin follows the cycle of movement of the driving drum with a permanent phase shift. The amplitude or frequency of the periodic function is varied in dependence on the increasing diameter of the cross-wound bobbin during the bobbin travel. The periodic cycle of movement of the driving drum is obtained either via an electric motor of a speed variable by means of an invertor or via a speed convertor arranged between the electric motor and driving drum. …<IMAGE>…

The sub-processor 5 includes electrically writable internal storage devices called a microprogram memory unit l3 and a sequence control memory unit 62 for storing the software. Peripheral functions to be implemented by the sub-processor 5 can be defined or modified by writing software into the memory units l3 and 62. Accordingly, the time it takes to define or modify the peripheral functions is the same as the time it takes to program the memory units l3 and 62. 
     The sub-processor 5 also includes an execution unit l6 for executing a plurality of tasks and an address control circuit l4 for providing addresses to the microprogram memory unit l3 in addition to the microprogram memory unit l3 for providing microinstructions to the execution unit l6. The sequence control memory unit 62 is part of the address control circuit l4 which also includes a plurality of address registers MAR0 to MARll. The sequence control memory unit 62 is used for storing information on what order the multiple address registers MAR0 to MARll are to be selected in sequentially. One of the address registers MAR0 to MARll is selected at every read cycle performed on the sequence control memory unit 62. A microaddress stored in the selected one of the address registers MAR0 to MARll is then supplied to the microprogram memory unit l3. Task null information can also be stored in the sequence control memory unit 62. The selection of one of the address registers MAR0 to MARll at every read cycle allows the sub-processor 5 to operate on an event driven basis.
