Abstract: A light source having a substrate having first and second surfaces is disclosed. The substrate has first and second conducting traces on the first surface. A heat conducting metallic layer is attached to the second surface. First and second LEDs are disposed on the first surface, each LED having first and second contacts for powering that LED. The first contact is connected to a corresponding one of the first and second conducting traces. First and second conducting vias are in contact with the first and second LEDs, respectively. The first and second conducting vias extend from the first surface through the substrate and contact the heat conducting metallic layer. The second contacts of the first and second LEDs are electrically connected to the first and second conducting vias, respectively. The LEDs are powered by applying potentials between the external terminals and the heat-conducting layer.

Abstract: A lancet activating device comprising a housing (3) which houses a reciprocating spring-loaded plunger (17), serving as a trigger to activate a lancet (26); cavity (5,6) for placements of a lancet (26) and a finger (23); apertures (9, 7) for the insertion of said lancet and said finger; leaf-spring (10) to position a finger (23). An unactivated fresh lancet (26) is inserted into the cavity (6) of the lancet activating device and the patient's finger (23) is placed into the cavity (5), whereby the finger positioning will be determined by the leaf-spring (10). At a press of the top mounted reciprocating plunger (17), the lancet (26) is activated to puncture the finger (23) and the patient proceeds to withdraw his finger and collection of the micro blood sample can proceed. Thereafter a fresh lancet (26) can be inserted into the cavity (6) of the lancet activating device from the lancet insertion aperture (9).

Abstract: A method of repairing an article, such as turbine parts of a rotary gas turbine engine, affected by sulphidation includes the steps of providing an article having a section affected by sulphidation, removing the affected section, and laser cladding a replacement section to the article.
