Patent CA-2509462-C (CA)

Abstract: Content-based addressing is used to navigate forward, backward and in a circular fashion through documents in a content space. To enable backward navigation, a descriptor file is created for a new version that contains not only a message digest for the new version, but also a message digest of the older document. A message digest is created for the descriptor file. A user navigates backward starting with the message digest of the descriptor file. To enable forward navigation, a mapping table maps a message digest of an older document into the message digest of the new version. A high-level descriptor file contains the message digest of the original document and the message digest of the mapping table. The message digest of the high-level descriptor file is returned to the user. A user navigates forward starting with the high-level descriptor file message digest. To enable circular navigation, a mapping table maps a message digest of a second document into a message digest of a version of the second document containing a message digest of a first document. The techniques are combined to allow navigation through a complex content space.

Abstract: A scanner instrument used for scanning tubing that is being placed into an oil well or being removed from the oil well can be calibrated during retrieval of tubing from the well. Calibrating the tube scanner includes scanning a tubing standard and comparing the data from the standard scan to the known characteristics of the standard. The relationship between the scanned data and the known characteristics can be computed. The relationship between the scanned data and the known characteristics can be used as the calibration function for the scanner. Calibrating the tube scanner can also include scanning a string of tubing segments and then adjusting the data collected. The adjustment is based upon equalizing the data peaks that occur in the scan data at the coupling joints between tube segments.

Title: Reactor for simultaneous separation of hydrogen and oxygen from water
Inventor: KONGMARK NILS
IPC: C01B13/02
Filed: 2004-12-16
Granted: 2012-06-05
Abstract: We disclose a device for the production of hydrogen from water using heat. The device employs thermal water splitting and works essentially without electricity. It is based on the concept of a membrane reactor with two kinds of membranes allowing the separation of hydrogen and oxygen simultaneously in stoichiometric quantities from the reactor volume. The device has a special geometry resulting in a temperature distribution inside the reaction chamber to accommodate the use of hydrogen selective membranes. The device will help to reduce the need for hydrogen transport and storage as it will be rather compact for on-site use in households, small factories or gas stations. The use of the device in mobile applications is conceivable. The heat source of the device as described is combustion of a hydrocarbon using porous burner technology; however the device can be modified to exploit any other heat source, especially solar radiation.

Abstract: A vehicle ignition interlock system includes a breath analyzer and a controller operably connected to the breath analyzer and to an ignition system of the vehicle. The controller compares detected breath alcohol levels of the vehicle operator with a threshold value, and is configured to prevent vehicle ignition if a breath alcohol level detected by the breath analyzer is greater than or equal to a threshold value. The controller also requires the vehicle operator to periodically take breath analyzer retests after vehicle ignition in order to allow vehicle operation to continue. The controller can reduce the frequency of periodic retests in response to one or more retests when the breath alcohol level of the vehicle operator is below a threshold value. The system may include a transdermal alcohol sensor, a mouth contamination sensor, and redundant alcohol sensors.
