Patent number: 7045046Abstract: The invention relates to a sensor adapted for electrical connection to a power source having an electrical contact means (3). The sensor has a first insulating substrate (1) carrying a first electrode (2) and a second insulating substrate (7) carrying a second electrode (6). The electrodes are disposed to face each other in spaced apart relationship, sandwiching a spacer (4) therebetween. A first cut-out portion extends through the first insulating substrate (1) and a spacer (4) to expose a first contact area (23) on the second insulating substrate (7). This permits the electrical contact means (31) to effect electrical connection with the first contact (23) which in turn is in electrically conductive connection with the second electrode (6). A similar contact arrangement may be disposed on the opposite side of the sensor.Type: GrantFiled: November 13, 2001Date of Patent: May 16, 2006Assignee: LifeScan, Inc.Inventors: Garry Chambers, Alastair McIndoe Hodges, Thomas William Beck, Ian Andrew Maxwell

Patent number: 7018533Abstract: A method of cleaning a membrane filtration module is disclosed. The module comprises at least one or more longitudinally extending membranes located in a feed-containing vessel. The membranes have a permeable wall which is subjected to a filtration operation wherein feed containing contaminant matter is applied to one side of the membrane wall and filtrate is withdrawn from the other side of the membrane wall. The method comprises the steps of suspending the filtration operation; performing a cleaning process on the membrane wall to dislodge contaminant matter from the membrane wall into liquid surrounding the membrane: performing a sweep of the feed-containing vessel substantially parallel to the longitudinally extending membranes to remove the liquid containing the dislodged contaminant matter, at least in part, through an opening in a header or other part of the module, and then recommencing the filtration operation.Type: GrantFiled: March 16, 2004Date of Patent: March 28, 2006Assignee: U.S. Filter Wastewater Group, Inc.Inventors: Warren Thomas Johnson, Thomas William Beck
