Abstract: A multiprocessor system linked by a fiber optic ring network uses some of the bandwidth of the ring network as a shared memory resource. Data slots are defined on the network which can carry message packets from one processor to another or network memory packets which circulate indefinitely on the network. One use of these network memory packets is as a lock manage­ment system for controlling concurrent access to a shared database by the multiple processors. The network memory packets are treated as lock entities. A processor indicates that it wants to procure a lock entity by circulating a packet, having a first network memory type, around the network. If no conflicting packets are detected when the circulated packet returns, the type of the slot is changed to a second network memory type indicating a procured lock entity.

Abstract: In a cooling system including a refrigerant compressor (21) for use in a vehicle for refrigerating a refrigerator compartment, the refrigerant compressor is a hermetic type compressor containing a DC brushless motor (21a) as a compressor driver. An electric generator (40) is actuated by an engine (101) of the vehicle to generate an AC electric power which is, in turn, rectified by a rectifier (30) to produce a DC electric power for driving The DC brushless motor. A switch (50) is provided to switch over from the electric generator to a commercial AC electric power (60) source so that the commercial AC electric power is rectified by the rectifier to supply the DC electric power to thereby enable to drive the compressor by use of the commercial AC electric power source during a time period when the engine is stopped. In order to obtain the accurate temperature control in the refrigerator compartment, during a time period when the engine is driven, generating amount of the AC electric power generated at the electric generator is controlled, and during a time period when the engine is stopped, delivering amount of the rectified commercial electric power which is delivered to the DC electric motor is controlled.

Abstract: In a data processing system, the time lost in checking for the presence of all memory references required byl a special section of code before the program is run is substantially reduced, and the program requiring the memory reference is dynamically protected from crashing if the memory reference is not presently available. The method assumes that all memory references are available and begins running (45) the special section of code without checking their availability. If a request is made for information that is not in assigned memory storage, a page fault occurs (47), and the data processing system interrupts the running of the special section of code (37) and undoes everything the special section of code has done prior to the interrupt (39). The requested memory reference is then located in storage (41), and the information is retrieved and written into assigned memory (43). The special section of code is then restarted and will now be supplied with the needed information. It has been found that in practice it takes much less time to assume the memory references will be present and occasionally interrupt, erase and restart, than to make a preliminary check for all memory references.

Abstract: 2.1 With value-added services, not only can the use of a data transmission system be made more attractive for the subscriber, but traffic quality can in most cases also be improved. Data transmission systems in which the possibility exists for implementing a value-added service are, for example, the car telephone system, the radiopaging system known as City-Ruf, etc. The possibility of setting up value-added services essentially exists for every information provider. One of the most difficult problems which the value-added service operator has to solve is the control of access authorisation for the value-added service subscribers and charge calculation. 2.2 With the new value-added service, a high degree of protection against abuse is afforded for both the value-added service operator and the value-added service subscriber, in that the reception authorisation is dependent on an identification code assigned to at least one group of radio receivers and on a key contained in the value-added service messages. This key cannot be displayed and defines the time period for the reception authorisation. 2.3 The new value-added service can be used in differently configured data networks for switched connections. <IMAGE>

A servo motor (81) adjusts the helical connection under the CPU so that the timing change mechanism need not be powered directly by the engine.

Abstract: A control logic for a vehicle brake system which is protected from blocking and is provided for off-road driving is proposed. In this case, the normal control logic for road driving is switched over by the driver by means of an off-road switch (13) to a special control logic for off-road driving. The special control logic is characterised in that it generates phases in which a brief blocking of the controlled wheels (12) is intentionally permitted. The blocking phases have a duration of approximately 240 ms. By means of the proposed off-road control logic, the brake path of the vehicle is shortened when off the road, and there is still sufficient sideways control. …<IMAGE>…

Abstract: The invention concerns a pickup coil to measure components of gradients. The coil consists of two pairs of loops connected in series; these pairs are then connected in parallel. The coil so formed has a low inductance, and no shielding currents are induced to superconducting coils in homogeneous magnetic fields. One coil can be employed to measure several field components simultaneously when the coil is coupled to current sensing elements, for example to SQUIDs, so that the current components measured by the sensing elements do not couple magnetically because of the symmetry. This can be accomplished by connecting the said elements between terminals between the loops (5, 6 and 7, 8). The inductance of this coil can be further reduced by subdividing the loops into parts connected in parallel.
