  • Management of units of work on a computer system log
    Patent number: 5745674
    Abstract: A method of moving records, stored on a recovery log, which are associated with units of work which have waited for a long time is described. Units of work which have waited for a long time, such as those which are in-doubt have their records copied from a recovery log to a secondary log. When the earliest-written record for this in-doubt unit of work has been copied, a new record called a fork record is written on to the recovery log which has two effects: to subtract the log records currently on the recovery log for this unit of work from the recovery log and to refer to the copied records written on the secondary log. The new record achieves this using two pointers, a pointer to point to the most-recently written record on the recovery log for this unit of work and a pointer to point to the most-recently written record on the secondary log for this unit of work.

  • Shape memory alloy fibers having rapid twitch response
    Patent number: 5092901
    Abstract: A modified shape memory alloy fibers exhibits a rapid twitch response under timulation by an action potential such as the heating effect of an electromagnetic pulse; in particular the relaxation time of the twitch response is considerably shortened as compared with that of the unmodified fibers; the modification is achieved by simultaneous application of a stretching force and a short, powerful electromagnetic pulse effective to bring about contraction resulting from the shape memory and change material properties; this application is carried out a plurality of times.
