Patent CA-2238518-A1 (CA)
Inventor: SNYDER WENDY J
IPC: G01N33/483
Filed: 1996-11-19
Abstract: A glucose monitor, and related method, determines the concentration of glucose in a sample with water, using a predictive regression model. The glucose monitor illuminates the sample with ultraviolet excitation light that induces the water and any glucose present in the sample to emit return light that includes raman scattered light and glucose emission or fluorescence light.  The return light is monitored and processed using a predictive regression model to determine the concentration of glucose in the sample. The predictive regression model accounts for nonlinearities between the glucose concentration and intensity of return light within different wavelength bands at a predetermined excitation light energgy or the intensity of return light within a predetermined wavelength band at different excitation energy levels. A fiber-optic waveguide is used to guide the excitation light from a laser excitation source to the sample and the return light from the sample to a sensor.

Patent CA-2285101-A1 (CA)
Inventor: GROVER WAYNE D
IPC: H04Q11/00
Filed: 1999-10-06
Abstract: Whether in a SONET or a dense-WDM (DWDM) transport environment, we can expect to see a continuance of the two main survivable architectures: ring and mesh. The differing advantages of these technologies has allowed both of them to find applications, although they are usually deployed and operate quite separately. To date, the problem of optimally combining ring and mesh technologies into a single integrated transport design remains largely unstudied. This patent document presents a planning principle and related optimization theory to strategically embed rings into a mesh network, with the purpose of obtaining a lower total design cost than that of either a pure-mesh or pure-ring design. The new design approach is based on a recently developed insight into the nature of spare capacity requirements in a mesh-restorable network. So-called "forcer" analysis identifies the spans that drive the dimensioning of spare quantities in the network. The main hypothesis is that strategic placement of rings onto these spans, can result in mesh sparing relief that more than pays for the cost of the rings. However, the very large number of possible ring placements and sizes, makes this a difficult combinatorial optimization problem. Both heuristic and Integer Programming approaches were used to solve the problem. Results show cases of hybrid designs that are 5 to 25% less costly than that of a pure mesh design, depending on the test network and the relative mesh-ring technology costs. The Integer Programming method worked well for networks with fewer nodes and spans, while the heuristic was needed to obtain good solutions for relatively larger networks.
