Title: Method for producing a membrane made of bridged polymer and a fuel cell
Inventor: KIEFER JOACHIM
IPC: H01M8/1246
Filed: 2002-03-01
Abstract: The invention relates to a membrane made of a bridged polymer produced by a method comprising the following steps: a) production of a solution comprising an alkaline polymer that contains at least one amino acid in a repeat unit and at least one bridging reagent in a suitable solvent, b) pouring of a film using the solution obtained in step a), c) accomplishment of the bridging reaction in the film obtained according to step c), d) doping of the film obtained according to step d) with a strong acid. The method is characterised in that in step a) an alkaline catalyst is also added. The inventive membrane displays visibly improved fracture toughness (elongation at rupture/tension) with near unaltered swelling behaviour. The inventive membranes are suitable for producing membrane-electrode-units for fuel cells.

IPC: H04N7/00
Filed: 2003-09-03
Abstract: Methods and devices for processing captured video frames to detect specific changes observable in video using three consecutive video frames. The images in the first video frame are compared with the second frame and the images of the second frame are compared with the third frame to produce two intermediate images which show the first order change observable in video. These interim images are then analyzed. A  geometric transformation is found such that when the transformation is applied to one of these intermediate images, the number of pixels which match between the interim is maximized. This geometric transformation, which may include a linear as well as a rotational component, is then applied to one of the intermediate images to result in a transformed image. The transformed image is then subtracted from the other intermediate image to arrive at an end image which shows the second order change or the change in a change observable in video. The second order change image will show only those specific pixels which have changed in the images between the three original video frames. The invention may be used to detect changes in the state of a subject's eyes. A subject's blinking can thus be used for sending binary commands to a computer remotely. In particular, a double blink, i.e.. two consecutive blinks, of a person can be used as a hand-free substitute to a clicking of a mouse.

Patent CA-2469579-A1 (CA)
Title: Explosively actuated tools
Inventor: ARNOLD AARON ANTHONY
IPC: B25C1/10
Filed: 2004-06-02
Abstract: An explosively actuated tool for driving a fastener into a substrate is of the type in which the tool is mounted to the end of a pole-like handle to permit manipulation and actuation of the tool from a remote position wherein actuation of the tool occurs by pushing the forward end of a barrel of the tool against the substrate using the handle and then pushing on the handle which loads and then releases the firing mechanism of the tool. A lock device is incorporated to prevent "air firing" of the tool by pushing the handle without the forward end of the barrel being pressed against the substrate. The lock device has a lock member which cooperates with the firing pin or firing pin spring support of the firing mechanism to lock one or other of those components unless the lock member is released by a prior displacement caused by retraction of the barrel when its forward end is pressed against the substrate.

Abstract: The present invention relates to a method for the aerobic digestion of a fluid waste material, notably an aqueous sewage, in which at least part of the waste material and/or of the digestion mixture is comminuted to reduce the median particle size of biomass and other solid particles in the digestion mixture to less than 10 micrometres, for example using destructive cavitation with a pressure drop of from 2 to 7.5 Bar. The comminution produces particles which are preferentially ingested by predator organisms in the digestion stage so that they graze on the bacteria and biomass particles and thus reduce the amount of biomass and suspended solids produced in the digestion stage. The invention also relates to apparatus for use in the method of the invention.
