Patent CA-2966748-A1 (CA)
Inventor: HIBRI NADI S
IPC: A61F2/44
Filed: 2015-11-04
Abstract: A multi-chamber balloon for a nuclear implant has an elastomeric membrane defining inner and outer chambers integral with a valve body. The valve body includes a core portion and sealing membrane for sealing the inner and outer chambers. An assembly for manufacturing the multi-chamber balloon includes a balloon mandrel which may be dip coated in a silicone dispersion to create an elastomeric membrane for the inner and outer chambers integral with the valve body. The elastomeric membrane formed on the mandrel is partially inverted to form a coaxial elastomeric structure with the smaller inner chamber disposed within the larger outer chamber. The valve is incorporated into the inner and outer chambers to form a unitary structure.

Inventor: GROSS PETER
IPC: G01V9/00
Filed: 2015-12-08
Abstract: Disclosed is a method and process for measuring oceanographic parameters that may be used to create estimates of the quantity of carbon dioxide gas that is removed from the atmosphere from an Ocean Iron Enrichment event. This process uses data observations from Autonomous Underwater Vehicles, Satellite observations and/or Unmanned Aerial Vehicles to determine metrics such as chlorophyll, temperature, turbidity, oxygen, particulate inorganic carbon etc. that may be used to calculate the total anthropogenic carbon dioxide that is removed from the atmosphere. Therefore, the carbon dioxide removal may be determined without requiring a manned presence in the area of study, providing a significant reduction in cost. Direct in-situ measurements of carbon flux through analysis of physical samples through the water column may be used as a verification/calibration metric using sediment traps spaced vertically in the water column from surface to the deep thermocline layer. Alternatively, water samples may be collected and used as an alternative.
