Patent CA-2696152-A1 (CA)
Inventor: TURNER PAUL
IPC: G05B13/04
Filed: 2001-06-27
Abstract: A constrained non-linear approximator for empirical process control is disclosed.  The approximator constrains the behavior of the derivative of a subject empirical model without adversely affecting the ability of the model to represent generic non-linear relationships. There are three stages to developing the constrained non-linear approximator. The first stage is the specification of the general shape of the gain trajectory or base non-linear function which is specified graphically, algebraically or generically and is used as the basis for transfer functions used in the second stage. The second stage of the invention is the interconnection of the transfer functions to allow non-linear approximation. The final stage of the invention is the constrained optimization of the model coefficients such that the general shape of the input/output mappings (and their corresponding derivatives) are conserved.
Patent CA-2697195-A1 (CA)
Inventor: ELLIOTT JOHN
IPC: G03B21/58
Filed: 2010-03-19
Abstract: A collapsible projection backwall system utilizes a short throw projector and a collapsible framework to create a display usable in a small amount of space.  The framework is specifically configured to support and appropriately position a flexible screen member so that distortion is avoided. This is particularly significant in situations where a relatively large screen is utilized, which creates the need to maintain appropriate tension upon the flexible screen member. The framework is specifically configured to be slightly canted when in its extended configuration to thereby introduce natural tension forces which will cooperate with the screen fabric to maintain the necessary configuration for the screen. This canted configuration is achieved by configuring a set of corner hinge assemblies and any central hinged assemblies to maintain this natural cant. By maintaining the desired forces on the display screen fabric a more efficient and functional display screen is created.

Inventor: HAMILTON JAMES
IPC: C01B31/02
Filed: 2009-01-07
Abstract: Solvents for macromolecules generally believed to be insoluble in their pristine form are identified by generation of a 'solvent resonance' in the relationship between solvent quality (deduced by Rayleigh scattering) and an intrinsic property of solvents. A local extreme of the solvent resonance identifies the ideal intrinsic property of an ideal solvent which may then be used to select a particular solvent or solvent combination.  A solvent for graphene is used in the production of transparent conductive electrodes.
