Abstract: A drive shaft assembly includes an outer shaft, an inner shaft, and an interface medium. The outer shaft defines a central channel. The inner shaft extends into the central channel and defines a clearance gap between an interior surface of the outer shaft and an exterior surface of the inner shaft. The interface medium is disposed in the clearance gap and rotationally couples the outer shaft and the inner shaft in an operational state of the drive shaft assembly. In response to a temperature of the drive shaft assembly exceeding a threshold temperature, the interface medium at least partially melts and rotationally uncouples the outer shaft and the inner shaft in a fault state of the drive shaft assembly.

Abstract: A P4 variant protein that has reduced enzymatic activity and that induces antibody to wild-type P4 protein and/or has good bactericidal activity against non-typable H. influenzae (NTHi) is useful as an active component in an immunogenic composition for humans. Methods of using these proteins, and compositions containing them in combination with additional antigens, are also provided.

Abstract: Whole cell phage-display techniques were used to identify several peptides that bound preferentially to a non-typeable strain of Haemophilus influenzae. These peptides were able to inhibit growth of both H. influenzae and Staphylococcal aureus. Thus, methods for treating bacterial infections, alone or in combination with traditional antibiotics, are envisioned.

Abstract: Certain components of an integrated circuit package are disclosed herein including one or more dies, each of which has an array of die output/input bond pads, and die support means, for example a substrate or leadframe, which includes an array of electrically conductive leads. There is also disclosed herein a technique for wire bond connecting the bond pads of a particular die to either the bond pads of a second die or to the electrically conductive leads of the substrate or leadframe using a thermosonic or thermocompression ball bonding tool. In accordance with this technique, where at least one die is involved, connections are made to the bond pads of that die by means of stitch bonding in a way which does not damage the die.
