Patent CA-2535326-A1 (CA)
Title: Compact manifolded fail-safe hydraulic control system
Inventor: PATTERSON ANDREW JOHN
IPC: F15B20/00
Filed: 2005-11-18
Abstract: A manifolded fail-safe hydraulic control system provides fail-safe operation of a pipeline valve using no more than a total of 45 proprietary parts in the system. The system controls the operation of a spring return actuator, which in turn strokes the pipeline valve from the normal operating position to the fail-safe position, or from the fail-safe position to the normal operating position. The system enables the valve to automatically stroke to its fail-safe position without external power.
Patent CA-2539005-A1 (CA)
Inventor: GRAY CHARLES L JR
IPC: F02B39/10
Filed: 2004-09-15
Abstract: This invention sets forth a commercially viable diesel combustion system tha t meets environmentally acceptable levels of NOx emissions (i.e. 0.2g/bhp-hr o r lower across a full map of engine speeds and loads) without the need for use of Nox aftertreatments, and simultaneously maintains engine-out PM emissions relatively close (e.g. with smoke levels at or below 3 BSN) to environmental ly acceptable PM post-aftertreatment levels. The invention achieves these resul ts by operating within a unique combination of parameters. These parameters comprise: (1) charge-air oxygen concentration below 16% preferably between 1 0% and 15%, more preferably between 11.5% and 14%, and most preferably between 12% and 13.5% for virtually all engine operating conditions (but not necessarily at no-load or low load conditions), (2) fuel injection pressures at or exceeding 1800 bar, preferably exceeding 2100 bar, more preferably exceeding 2300 bar, and most preferably exceeding 2500 bar, at most engine speeds an loads, and (3) charge-air mass/fuel mass ratio between 25:1 and 45 :1 for medium and high loads. Furthermore, the system is preferably run continuously slightly lean of stoichiometry, providing just enough excess oxygen to facilitate completeness of combustion and to maintain an exhaust oxygen concentration sufficient for continuous trap regeneration at a balanc e point in operation.

Title: Methods and apparatus for the utilization of core based nodes for state transfer
Inventor: PARK VINCENT
IPC: H04W80/04
Filed: 2004-01-26
Abstract: Methods and apparatus for storing, manipulating, retrieving, and forwarding state, e.g., context and other information, used to support communications sessions with one or more end nodes (144, 147), e.g., mobile devices, are described. Various features are directed to a mobile node controlling the transfer of state from a first access node (140) to a second access node (140~) during a handoff operation thereby eliminating any need for state transfer message to be transmitted between the second access node and the first access node during handoff. Other features of the invention are directed to the use of a core network node (104) to store state information. State information stored in the core node can be accessed and used by access nodes in cases where a mobile node does not send a state transfer message during a handoff, e.g., because communication with the first access node is lost or because such messages are not supported.

Patent CA-2563527-A1 (CA)
Inventor: BUHLMANN REINER
IPC: B05B15/00
Filed: 2005-04-01
Abstract: The object of the invention is to give a coloured, temperature-dependent appearance to the water flowing out of a hot-water fitting. For that purpose, three temperature ranges are formed and a colour is associated with each of the temperature ranges. The three ranges correspond to too cold, too hot and desired temperature ranges. A lever (4) is actuated to cause a water jet (20) to flow out of the fitting. Depending on the position of the lever (4), only cold water, only hot water or mixed proportions of cold and hot water flow into the mixing chamber (7). Depending on the temperature measured in the mixing chamber (7), a control block (13) drives diodes (17) arranged at the outlet of the hot-water fitting and having a colour which corresponds to the temperature range in question, causing the diodes to emit light. The water jet (20) flowing past the diodes (17) is illuminated with said colour. The user of the fitting can recognise the water temperature from the coloured appearance of the water jet (20) and if necessary correct it by actuating the lever (4).

Abstract: An image locking system for DNA micro-array synthesis provides a feedback system to stabilize or lock the image with respect to an image capture device, such as a camera and/or microscope. The image locking system includes the use of detection or reference marks. When a shift in image position is detected, a correction signal is sent to one of two mirrors, moving the image to correct for the shift in image position. The system comprises a first light beam directed towards a micromirror device that forms an alignment pattern on a reaction cell and a second light beam directed towards the micromirror device that forms a micro-array image on an active surface of the reaction cell. A  camera captures the alignment pattern and an alignment mark. A computer calculates a correction signal to realign the alignment pattern with the alignment mark when movement is detected.
