Patent CA-2312960-A1 (CA)
Inventor: HANSON THOMAS A
IPC: H04B10/556
Filed: 1998-12-03
Abstract: An all optical add-drop multiplexer (ADM) includes nonlinear optical loop mirrors (NOLMs) (302, 304) having signal input (I1), gating input (G1), through output (T1) and drop output (D1) ports. A stream of soliton pulses coupled to the gate input (G1), synchronized with soliton signal pulses coupled to the signal input (I1), directs the signal pulses to the drop output (D1) or to the thro output (T1), depending upon the presence or abscence of solitons in the gate signal. Operations such as logic INVERSION and logic AND  are effected by the NOLMs (302, 304) and signals may be added through a combination of operations equivalent to a logic "OR". Such combinations are employed to produce one or more drops and one or more adds in an add-drop multiplexer.

Patent CA-2323850-A1 (CA)
Inventor: WOLKOW ROBERT A
IPC: B82B3/00
Filed: 2000-10-19
Abstract: The invention provides a method for producing an ordered nano-structure on a substrate surface, wherein the surface has an anisotropic lattice. A single radical is generated at a site on the lattice, and reaction with a chain propagating organic molecule is initiated. The chain-propagating organic molecule forms a covalent bond with the surface, and in turn forms a radical, which reacts, in a manner specific to the surface anisotropy, to form a second radical site on the lattice. This sequence continues, building up an ordered nano-structure on the surface, the structure of which is dictated by the surface structure.  Preferred substrates are semiconductors, such as Si(100) and Ge(100).

Title: Moisture indicator for wet pick-up suction cleaner
Inventor: GORDON EVAN A
IPC: A47L11/40
Filed: 2001-06-20
Abstract: The moisture sensor and indicator for a wet pickup vacuum cleaner, more particularly a wet extraction type carpet cleaner, is positioned in the suction duct to sense when water droplets or moisture is traveling through the suction duct.  An indicator is activated to indicate to the operator that water is being extracted from the carpet. The sensor may alternatively be located in the bottom of the floor-engaging portion where it contracts the floor. When the degree of moisture in the carpet exceeds a predetermined threshold an indicator is activated to indicate to the operator that the floor is still wet and to continue extracting moisture from the floor. Alternatively, the moisture sensor can be used as a safety device on a dry pickup vacuum cleaner. When moisture is detected within the suction duct, the motor-fan assembly of the dry pickup vacuum cleaner is disabled to prevent a potentially hazardous condition. Also, another moisture sensor is positioned in the cleaner to detect when the moisture level of the solution or recovery tank is reaches a predetermined level. An indicator is activated to indicate to the operator when the moisture level reaches the predetermined level.

Title: Building levelling system
Inventor: ROBBINS ROBERT RALPH
IPC: E02D31/10
Filed: 2001-07-18
Abstract: A building levelling system is provided for a building having a basement or foundation supported on expansive soil. A water management system is included for maintaining water in the expansive soil at a level adjacent the foundation to saturate the soil with water and thereby prevent the cyclic shrinking and expanding of the soil when the soil is normally repeatedly dried and wetted, causing damage to the building supported thereon. An injection system may also be included for injecting water into the soil spaced well below the foundation to lift a foundation which has already settled significantly due to shrinkage of expansive soil upon which it is supported. The injection system includes a level sensing mechanism for determining when a level of water in a prescribed area of the expansive soil falls below a reference level of the system and injectors for feeding water into that area.
