A computer having a storage subsystem and an array controller circuit controlling an array of hard drives in the storage subsystem. Upon powering the storage subsystem, the array controller automatically determines whether the hard drives have been moved to new bay locations in the storage subsystem and whether a new complete logical drive, consisting of at least one hard drive, has been added to ...

A pipelined CPU executing instructions of variable length, and referencing memory using various data widths. Macroinstruction pipelining is employed (instead of microinstruction pipelining), with queueing between units of the CPU to allow flexibility in instruction execution times. A wide bandwidth is available for memory access; fetching 64-bit data blocks on each cycle. A hierarchical cache arra...

A technique for extending the data word size and the virtual address space of a pre-existing architecture so that hardware for the extended architecture also supports the pre-existing architecture. Extension of the data word size from m bits to N bits entails widening the machine registers and data paths from m bits to N bits and sign-extending entities of m or fewer bits to N bits when they are l...

A second lead frame portion (4) has a bed portion (8) for mounting a semiconductor element (9) and a plurality of inner and outer leads (2, 3) as in the first lead frame porti...

The system has an alarm system which reacts differently to different abnormal conditions. In more serious conditions dialysis operation is suspended and user intervention is required to resume operation. Where a less serious abnormal condition occurs, the dialysis operation is allowed to continue for a certain time and, only if the condition persists, is the operation suspended.

Non-radioactive chemically-labeled polynucleotide probes, such as non-radioactive chemically-labeled, single-stranded DNA probes, are hybridized to fixed, denatured, single-stranded genetic material having a make-up complementary to said probes for determining the identification and/or presence of said genetic material. The non-radioactive chemical label on said probe is employed to elicit a respo...

A process for discriminating sequence variants of a target nucleic acid is described. In this process variant specific cleavage products of a labeled oligonucleotide probe are produced by the 5'-3' exonuclease activity of a template dependent nucleic acid polymerase, which allows to identify the sequence variants present in a sample.
