Patent EP-0385537-A2 (EP)
Inventor: MCGEE PHILIP JOSEPH L C O INT
IPC: G11B7/125
Filed: 1990-02-21
Abstract: A method is described which enables automatic determination of the monitor sensitivity of a radiation emitting arrangement (in particular a laser diode and photodiode arrangement), which monitor sensitivity relates a level of a monitor signal (I M ) generated by the arrangement to a corresponding optical output level (O L ) of the arrangement. The method comprises the steps of: (i) supplying a varying drive signal (I L1 ,I L2 ) to the arrangement and measuring the rate of change (ΔI M /ΔI L ) of the monitor signal (I M ) with respect to the supplied drive signal (I L ); and (ii) combining the measured rate of change with an assumed differential efficiency (k) of the arrangement to determine the monitor sensitivity (O L /I M ) of the arrangement. The provision of a control system able to implement such a method can eliminate the need for a factory adjustment in the maufacture of apparatus such as optical recording and/or reproducing apparatus.

Abstract: A microprocessor system which includes a processor unit with system memory and a separate buffer memory, one or more subsystem adapter units with memory, optional I/O devices which may attach to the adapters, and a bus interface. The memory in the processor and the memory in the adapters are used by the system as a shared memory (106,112) which is configured as a distributed FIFO circular queue (a pipe). Unit to unit asynchronous communication is accomplished by placing control elements (104,116) on the pipe which represent requests, replies, and status information. The units (622,624) send and receive control elements (104,116) independent of the other units which allows free flowing asynchronous delivery of control information and data between units (622,624). The shared memory (106,112) can be organised as pipe pairs between each pair of units to allow full duplex operation by using one pipe for outbound control elements (104,116) and the other pipe for inbound control elements (104,116). The control elements (104,116) have standard fixed header fields with variable fields following the fixed header. The fixed header allows a common interface protocol to be used by different hardware adapters. The combination of the pipe and the common interface protocol allows many different types of hardware adapters to asynchronously communicate, resulting in higher overall throughput due to lower interrupt overhead.

Abstract: A memory in a task switching system includes, for example, five memory banks (0 to 4) and one common area. Physical address areas (2000H to 13FFFH) different from each other are respectively assigned to the memory banks (0 to 4), and common apparent addresses (2000H to 7FFFH) are assigned to each of the memory banks (0 to 4). In addition, the common area stores a task control block including start address information, stack pointer information, queue information, bank information and the like. At the time of task switching, any one of the five memory banks (0 to 4) is used as a memory bank for reading on the basis of the bank information in the task control block and a task is read out on the basis of the apparent addresses (2000H to 7FFFH) assigned to the memory bank.

Abstract: A body is hermetically sealed by electroplating a hermetic layer over the exterior surface of the body. A high density interconnect structure (100) is hermetically sealed by forming a continuous metal layer (144) over the outermost dielectric layer (160) of the multilayer interconnect structure and by disposing that continuous metal layer in a hermetically sealing relation to the substrate (112) of the high density interconnect structure. A variety of techniques may be used for providing electrical feedthroughs (118) between the interior and exterior of the hermetic enclosure as may a pseudo-hermetic enclosure in those situations where true hermeticity is not required.

Abstract: The method and apparatus for maintaining active sessions between communicating logical units (10, 40) in a computer network when an application system fails without having to re-establish the active sessions, are carried out by activating a persistent session capability at one of the logical units. Thus, the active sessions can be suspended and maintained while attempts at recovery are made. Recovery attempts include restarting the failed applica­tion or switching the suspended sessions to an alternate instance of the logical unit (10). The suspended sessions are re-synchronized with the application system and ses­sion activity is resumed.

Abstract: A microcomputer system memory controller architecture and method permits high speed access to data in the system memory (102), allowing the system memory (102) to operate in a burst mode. The architecture and method utilizes a system memory controller (108, 208) capable of performing the addressing of the system memory (102) without constant supervision by the microprocessor (106, 206). The microprocessor (106, 206) and the system memory (102) electrically communicate by way of a host bus (204). The memory controller (108, 208) generates second addresses corresponding to data locations in system memory (102) upon receipt of the initial address of a set of first addresses from the microprocessor (106, 206). Accordingly, the microprocessor (106, 206) can access data in the system memory (102) at an extremely fast rate when attempting to read in a burst mode. High speed access is accomplished without the need for an external cache.

Abstract: To an increasing extent, vegetative foodstuffs such as vegetables and salads are not prepared freshly at the point of use but are prepared remotely and distributed to catering establishments or via the retail trade. It is desirable to disinfect such pre-prepared foodstuffs, but the use of an aqueous solution of an organic peracid can reduce the shelf life of the foodstuff by causing or exacerbating discolouration and/or decrisping. 
     The problem is ameliorated by subsequently contacting the disinfected foodstuff with a neutralising solution of thiosulphate. The process is particularly suitable for potatoes, beansprouts and leaf vegetables such as cabbages and lettuces.

Abstract: An LED pulse shaping circuit (10) capable of providing improved rise time (using current peaking) and fall time (using charge extraction) comprises a conventional differential current switch (12, 14, 16) coupled to a pair of switching elements (24,26) and resistance elements (20,22). A first switching element (24) is activated at the beginning of a pulse to provide an initially increased drive current to the LED, depending on the value of a first resistance element (20). The current peaking thus decreases the rise time of the LED. The remaining switching element (26) and resistance (22) are utilized, in conjunction with the differential current switch, to provide a reverse current flow through the LED at the end of the pulse. The charge extraction thus decreases the fall time of the LED.

The state of charge of the floating gate, imposed by programming or erasing, may be such as to reach advantageously a potential higher than the supply voltage or lower than the ground potential of the circuit. The floating gate directly drives the ON or OFF states of the two complementary transistors (T1,T2). On the output node represented by the common drain of the pair of transistors a signal present on a source node of one or the other of the two complementary transistors may be replicated.

Abstract: 2.1. Enzymatic reactions are sometimes adversely affected by water, for example water added to the reaction mixture may hydrolyse the reaction product or, for example in the case of a condensation reaction, the equilibrium may be shifted towards the starting materials. In reactions of these types, the water is usually replaced by a solvent which, however, interacts with the enzyme and thereby frequently alters the latter in an unfavourable way. Hydrolytic side reactions are to be substantially avoided in the disclosed process. 2.2. In a water-assisted enzymatic reaction, the substrate and the enzyme are present in solid phase with either the water not forming a liquid continuum around the substrate and enzyme or the water acting at least partially from the gas phase, or the water required for the reaction being added via a solid, or at least part of the water required for the reaction being transferred by solid contacts, or a combination of the possibilities. The reaction mixture can be mixed by ultrasound or turbulence, for example in a fluidised bed. 2.3. Preparation of peptides.
