Patent CA-2320216-A1 (CA)
Inventor: TAYLOR JAMES P
IPC: F02G1/04
Filed: 1999-02-12
Abstract: A low or no pollution engine (20) is provided which collects air from a surrounding environment. After removing a portion of the nitrogen, the remaining gas is primarily oxygen, which is routed to a gas generator (70).  The gas generator has an igniter and inputs for the high pressure oxygen and a high pressure hydrogen-containing fuel, such as hydrogen, methane or a light alcohol. The fuel and oxygen are combusted within the gas generator, forming water and carbon dioxide with carbon containing fuels. The combustion products are then expanded through a power generating device (48). The combustion products are then passed through a condenser (80), and then is routed back to the gas generator. The carbon dioxide is compressed and cooled so that it is in a liquid phase or super critical state. The dense phase carbon dioxide is then further processed from which return of the CO2 into the atmosphere is inhibited.

Patent CA-2324419-A1 (CA)
Title: Method and apparatus for frequency tuning of an unbalanced mach-zehnder interferometer
Inventor: AHMADVAND NIMA
IPC: G02B6/34
Filed: 2000-10-25
Abstract: The present invention introduces a novel and simple method to adjust the MZ filter channels to those of the ITU grid. This is done through inducing an optical path length difference by using a UV light source to create a change in the index of refraction of the fiber arms after the device is packaged.   The UV light is launched into the MZI filter through one of its input ports in order to achieve the phase adjustment. Since the exposure length is the entire length of one of the arms of the MZI, the required refractive index change is much smaller than the localized UV tuning of the previous methods.   This allows for a weaker UV source power and shorter treatment times, thus reducing the chances of localized fiber damage.

Patent CA-2339893-A1 (CA)
Inventor: JAGANNATHAN RAJESH S
IPC: H04B10/291
Filed: 2001-03-02
Abstract: A network manager begins to integrate optical crossconnect functionality in an optical packet switching apparatus by transmitting a request to a resource management mechanism for allocation for an output port with respect to an input port in an optical switching matrix. The resource management mechanism then queries a port availability database to determine the availability of the requested output port. If an output port is available, the resource management mechanism then reserves the requested output port. The resource management mechanism then transmits mapping information for an optical path between the input port and the reserved output port to an optical switch control mechanism. The optical switch control mechanism then creates the optical path between the said input port the reserved output port.      Finally, the optical switch control mechanism informs the resource management mechanism that the optical path is established.

Abstract: Apparatus and method is provided for performing detailed mine detection over variable terrain. An articulated robotic scanner (1) comprises an articulated arm (2) mounted to any vehicle such as a robot. One or more mine detectors (3) mounted at the end of the arm. The arm operates autonomously to repetitively sweep the mine detector in ever forward advancing side-to-side arcs over the terrain. The vehicle can operate autonomously or-be teleoperated. The position of the mine detector is monitored and known with respect to a known co-ordinate system. Sensors (4, 5) measure their position relative to the ground and relative to known co-ordinates of the mine detector. A controller determines the relative position of the ground and the mine detector and dynamically adjusts the mine detector's position to maintain a constant separation over variable terrain without ever contacting the ground or objects thereon.
