Patent EP-0372692-A2 (EP)
Inventor: BIANCO JAMES SALVATORE
IPC: G06K19/14
Filed: 1989-10-05
Abstract: An identification code has both general information which is encrypted using standards symbologies and security information which is encrypted using a unique symbology. In the case of bar codes, the bar code may include two separate sets of bars. One set of bars may include basic information, for example an employee's identification number, encrypted using standard symbologies which may be read in any standard reader. The other set of bars includes security information which is encrypted using a unique symbology which can be read only in a special reader and which is meaningless to a standard bar code reader or bar code duplicator. Thus, where security is a factor, the special readers would be provided; but, where security is not a factor, the basic identification could be read by any standard reader.

Abstract: A 64 bit wide memory is multiplexed over a 32 bit data bus to provide data to a 64 bit line size cache memory controlled by an 82385 cache controller. The memory addresses to all 64 bits of memory are held during the entire transfer so that a zero wait state second 32 bit transfer occurs. Logic develops the necessary next address and ready pulses and blocks these signals from the cache controller. Logic also handles the bit 2 address for the main and cache memories. The main memory is operated in paged mode to further increase system performance.

Abstract: The invention is concerned with a method and apparatus for impregnating fibre bundles by means of molten or liquid resin (32) in the course of manufacturing fibre-reinforced material (which material comprises one or more fibre bundles in which each fibre is surrounded by matrix resin) by impregnating a continuous web (10, 10a) of one or more fibre bundles with a molten or liquid resin (32) and solidifying the resin (32) by cooling or chemical reaction. Before impregnation, the molten or liquid resin material (32) is subjected to shear forces by forcing it to flow through a channel (31) communicating with an impregnation point (34, 37), the channel containing at least one part having decreasing cross-section and/or said channel having a cross-section sufficiently narrow to cause shear forces in the molten or liquid resin material (32) to decrease its viscosity.

Abstract: An efficient cache (2) utilizing a store buffer (21,22) includes an address tag (14) which contains address tags (121) and includes a data (30) which contains cache data. An index is used to address both the address tag (14) and the data RAM (30). In front of the data RAM (30) is placed a data register (22) and an address register (21). At the beginning of a write cycle a comparison is made between an address tag (121) portion of a data address and an address tag (121) obtained by accessing the address tag RAM (14) using an index portion (122) of the data address. If these are equal this indicates a data block including a data word into which data is to be written is extant in the data RAM (30). A valid signal is then forwarded to the address register (21) and the data register (22). Also at the beginning of the write cycle the data register (22) loads into the data RAM (30) data stored in the data register (22) at the address specified by the address register (21). New data to be written is placed at the input lines of the data register (22). The index portion (122) of the data address is place at the input lines of the address register (21). A valid signal from the address tag RAM (14) causes the address register (21) and the data register (22) to store the values on their respective input lines. If no valid signal is forthcoming, the address register (21) and data register (22) retain their current values, and a cache miss is generated. A comparator (24)   and two multiplexors (23,28) are added to the system to assure that data stored in the data register (22) is available to be read even before it is stored in the data RAM (30). The principles of equipping a cache with a data SRAM with store buffer may be used in other applications including partial word storage and access of dirty bits. Additionally the principles may be used in the construction of a multi-set associative cache.
