The invention is based on the use of a Lange fast Kalman filter FKF in large process control, prediction and warning systems where other calculation methods are too slow or suffer from large rounding errors.

The invention relates to an automatic two-chamber injector for mixing and injecting a medical solution. The injector comprises a barrel (11) having a first end with a receiving portion (15) for an injection needle (17), said portion being sealed prior to use, and a second end with a displaceable plunger (27). The barrel (11) comprises two chambers (29, 30) separated by a migrationproof membrane (2...

In a microcomputer system comprising a microprocessor and a cache subsystem and operable in a pipelined mode, there is potential incompatibility between pipelined operations and dynamic bus sizing as the cache subsystem operates with a fixed size data width and dynamic bus sizing allows the system to operate with devices of differing data width. This incompatibility is accommodated by the present ...

The present invention provides nucleic acid molecules containing nucleotide sequences encoding helminth aminopeptidase enzymes, and antigenic fragments and functionally-equivalent variants thereof, their use in the preparation of vaccines for use against helminth parasites, and synthetic polypeptides encoded by them.
