Title: Efficient optical wavelength multiplexer/de-multiplexer
Inventor: BALL GARY A
IPC: H04B10/278
Filed: 1995-09-22
Abstract: An efficient wavelength multiplexer/demultiplexer includes a plurality of 2x2 optical couplers (122, 180, 200, 220), each having a pair of matched gratings (130, 142; 182, 184; 202, 204; and 222, 224), having bandpass wavelengths (.lambda.1, .lambda.2, .lambda.3, .lambda.4), respectively, attached to two of the ports. An input signal (116) enters a port (120) and is split and reflected off the gratings (130, 142) and then recombined so as to provide all the input signal (116) at an output port (150) and no reflection out of the port (120). Another input signal (154) is incident on the grating (142) which is passed by the grating (142) and is coupled onto the output port (150) with the signal (116) as a signal (160). A similar arrangement exists for the other couplers (180, 200, 220) connected in series, each of which adds another input wavelength. Alternatively, in a de-multiplexing application the signal (116) may be broadband and the signals (154, 190, 206, 230) would be separate output wavelengths.

Title: A system for automated interface generation for computer programs operating in different environments
Inventor: STEPHENSON JOHN WRIGHT
IPC: G06F9/44
Filed: 1997-03-27
Abstract: A system for automated interface generation for computer programs operating in different environments. The system comprises a utility which imports a CICS COBOL transaction source file, parses the communication area of the CICS file, and generates modelling information. The modelling information represents the nature and structure of data in the CICS transaction source file, and is written to a persistent data store. The utility uses the information in the persistent data store to generate an application programming interface. The application programming interface takes the data values from the other language and translates them to a formatted CICS COBOL communications area. This format is derived from the definition of the CICS communications area contained in the imported CICS program. After the translation runs, the resulting CICS COBOL communications area is translated back to the data values of the other language. This translation step also handles the data conversion between different codepages and machine architectures and program semantics. The resulting language values represent the result of the transaction. The CICS transaction is accessed using the CICS External Call Interface mechanism.

Title: Process for polymerising cyclic olefins and a photopolymerisable composition
Inventor: VAN DER SCHAAF PAUL ADRIAAN
IPC: C08G61/08
Filed: 1995-11-06
Abstract: The proposed process for polymerising a cyclic olefin or at least two different cyclic olefins in the presence of a metal compound as catalyst is characterised by the fact that photochemical ring opening metathesis polymerisation is carried out in the presence of a catalytic quantity of at least one thermostable niobium (group V) or tantalum (group V) compound containing at least two methyl groups or two monosubstituted methyl groups bound to the metal; the substituent contains no hydrogen atom at the .alpha.-position. The process can also be conducted in such a way that irradiation is carried out first and polymerisation is completed by heating. The process can be used in the production of thermoplastic moulding materials, coating and reliefs.
Patent CA-2205588-A1 (CA)
Inventor: REHMAN SAEED UR
IPC: H02P6/18
Filed: 1996-09-19
Abstract: A method for estimating and controlling the rotor position of a SR motor comprises the steps of sampling phase current(s) (53) and estimating phase flux(es) (54) from at least one conducting phase of the SR motor, sampling phase current(s) (52) and estimating phase inductance(s) (54) from at least one unexcited phase of the SR motor, and determining the rotor position (55) by combining the estimated phase flux and the estimated phase inductance (54).  Once the rotor position has been determined/estimated by the above method, the position of the rotor can be controlled so as to provide, overall, and effective control of the SR motor. In particular, once the position of the rotor is determined/estimated, the excitation provided to the motor is then adjusted (56) to urge the rotor from its current position towards its desired position. In this way, position control of the motor can be obtained. Of course, this can be extended to obtain velocity control as well.

Title: Integrated optical system for endoscopes and the like
Inventor: HOOGLAND JAN
IPC: G02B23/24
Filed: 1995-12-06
Abstract: Optical systems for endoscopes, borescopes, dental scopes, and the like, having three groups of lenses of positive optical power and an external entrance pupil (P). Typically, all three groups are displaced from the pupil (P) and focal planes (F). The displaced groups participate in the image transfer and pupil transfer. Optical power can be shifted from one group to another, distributing and reducing the overall power requirement, and aberration correction can be shared among these groups. The first group, which conventionally has the highest optical power and associated aberrations, can thus transfer some of the aberration correction to other groups. The sharing of these optical functions results in a fully integrated optical system. The total optical power is so reduced that a line-of-sight deviating prism (2) can be accommodated between the entrance pupil and the first lens group. The resulting simplicity makes the optical system suitable as a disposable item.
