Abstract: In some examples, there may be provided systems, devices, and methods for using data from disparate sources to determine whether diversion events have occurred. A diversion event may be when a monitored unit intended for a target user is diverted away from the target user.

Abstract: A method of producing a fluted drill in which the flutes are formed by grinding a generally cylindrical blank using a grinding wheel having a profiled circumferential face for generating the cross-sectional form of the flutes is characterized in that the radial cross-section of the profiled circumferential face of the grinding wheel includes a main cutting portion having a convexly curved profile, and a secondary cutting portion forming a continuation of the main cutting portion, there being a change in profile shape at the junction between the main and secondary cutting portions with the secondary cutting portion extending outwardly, away from the extended curve of the main cutting portion profile, to a radially outermost peak of the circumferential face.

Abstract: As will be described in more detail hereinafter, there is disclosed herein a titanium nitride diffusion barrier layer and associated method for use in non-silicon semiconductor technologies. In one aspect of the invention, a semiconductor device includes a non-silicon active surface. The improvement comprises an ohmic contact serving to form an external electrical connection to the non-silicon active surface in which the ohmic contact includes at least one layer consisting essentially of titanium nitride. In another aspect of the invention, a semiconductor ridge waveguide laser is disclosed which includes a semiconductor substrate and an active layer disposed on the substrate. A cladding layer is supported partially on the substrate and partially on the active layer. The cladding layer includes a ridge portion disposed in a confronting relationship with the active region.
