IPC: G06F17/50
Filed: 1991-06-05
Abstract: A motion analyzing method using dynamics comprises forming a model of a moving body such as a human or animal body. The model has a plurality of segments connected by joints. Actual motions of a moving body are applied to the model. The forces and torques acting on each segment of the model as a result of the motions, and the positions of and forces acting on the centers of gravity of the segments and the entire model are calculated by dynamics. The results can be displayed on a screen superimposed on a picture of the model.

Title: Process for the enzymatic treatment of substrates
Inventor: RUDOLPH RAINER
IPC: C07K14/16
Filed: 1991-01-18
Abstract: A b s t r a c t For the enzymatic treatment of substrates, the substrate to be treated is brought into contact with a biocatalyser which was obtained by combining, in order to produce a fusion protein, a gene which codes for a biologically active substance and a DNA fragment which codes for a binding peptide which can interact with a carrier material then inserting the combined gene and DNA fragment into a suitable vector, transforming it in a suitable organism, culturing the organism, lysing the cells and bringing the lysate into contact with a carrier material which is capable of binding the binding peptide whereby the fusion protein binds to the carrier material by intermolecular interactions and the enzymatically treated substrate is subsequently isolated.

Patent CA-2050501-A1 (CA)
Title: Circuit test method
Inventor: WILSON ALICE
IPC: G01R31/28
Filed: 1991-09-03
Abstract: The present invention relates to a method of testing of digital and analog circuits. If a fault is detected, after stimuli are applied and test measurements are made at some circuit nodes, steps are taken to locate faulty circuit components. At least one further node is selected for measurement on the basis of the levels of information that such nodes can provide. Further measurements aid fault location. For anolog circuits, levels of information are determined by calculation of discrimination factors which depend on possible voltage ranges at unmeasured circuit nodes if various components are considered as faulty. The information gained from measurment at a further node is used to reduce the voltage ranges in order to aid selection of another node to measure.

A user enters information, including a control sum, for each meter and the system combines it with other information stored in the data bank to form messages.  The system then enters into transactions with the remote data processing center to obtain recharge codes for each of the meters, which are then displayed for entry into the meters.         In another embodiment the system may communicate directly with each meter through a local communications network.

Title: High efficiency, flux-path-switching, electromagnetic actuator
Inventor: NIELSEN WYN Y
IPC: H01F7/16
Filed: 1990-07-31
Abstract: An electromagnet (400) defines a gap between a first polepiece (410) in the shape of the butt end of an elongate cylinder and a second polepiece (420) in the shape of a thick annular ring. A  permanent magnet (440) having its poles aligned along the axis of the cylinder moves bidirectionally in the gap in response to alternate polarity energization of the electromagnet (400), serving as a prime mover. When the electromagnet (400) is not energized then the magnetic flux of the permanent magnet shunts an adjacent polepiece (400 or 420, as in the case may be), holding the magnet in place. Upon energization of the electromagnet the relatively strong magnetic flux of the permanent magnet (440) is switched by a relatively weak electromagnetic flux to pass through the electromagnet (400), exerting an electromotive force on the permanent magnet (440) and causing it to move. Typically a one-half gram samarium cobalt permanent magnet moves 0.38 mm in response to a 0.015 ampere 1.5  v.d.c. 20 millisecond current pulse (4.5 x 10-4 joules) and holds at 40± 2g's. dislodging acceleration at each of two stable positions where no power is consumed.
