| 20100206534 | HEAT EXCHANGER AND METHOD OF PRODUCING THEREOF - The invention concerns a heat exchanger and a method of producing thereof. The heat exchanger comprises a coolant housing with two opposing wide side walls and two header plates of an inlet air tank and an outlet air tank, respectively. The header plates are channel-shaped with longitudinal flanges extending over and being brazed to the wide side walls. Tubes extend in parallel through said housing between the two header plates, said tubes being brazed to apertures in said header plates. The coolant housing has two opposing narrow side walls tightly fitting said wide side walls and said header plates and defining together with these wide side walls and header plates a first coolant tank and a second coolant tank opposing the first one. Each air tank comprises a cowling tightly fitting and being brazed to one of said header plates each and having an air inlet and an air outlet, respectively. At least one of said two side walls is welded to said wide side walls and said header plates thus enclosing said housing. | 08-19-2010 |

| 20110282180 | SWITCH PROBE FOR MULTIPLE ELECTRODE MEASUREMENT OF IMPEDANCE - The present invention provides impedance data having an improved spatial resolution, both with regard to depth and lateral extension, which enables a detection of diseased skin conditions, such a malignant melanoma, at an early stage. Specifically, the present invention is implemented in a probe, medical devices and medical systems including such a probe, and methods using such a probe for measuring electrical impedance of tissue of a subject. A switching circuit is arranged for selectively activate electrode pairs of the probe in accordance with a predetermined activation scheme, the predetermined activation scheme including to activate adjacent electrodes in a successive manner, to gradually scan tissue of the subject at a first tissue depth so as to obtain a sequence of impedance signals from the tissue depth. | 11-17-2011 |
