Abstract: A heat sink employs a scalloped surface profile to facilitate interface to thermally conductive materials. The scalloped surface profile reduces the surface area initially as the thermally conductive material is compressed for assembly. The reduced surface area allows the required compression force to be decreased, which helps reduce the risk of damages to the heat generating devices due to excessive force. The scalloped surface profile increases the final surface area in contact with the thermally conductive material after assembly. The increased final surface area helps improve the transfer capacities of the heat sink.

Abstract: A fastener device includes a self-clinching retainer and a blind fastener. The self-clinching retainer is mounted to a hole in a sheet. The blind fastener is at least partially floating within the self-clinching retainer. The blind fastener has blind thread so that any debris from engaging another fastener is captured within the blind fastener.

Abstract: An assembly including an introducer cannula and subcutaneous measurement device, and a method of its use. The device can form an aseptic seal to the introducer to resist passage of pathogens through the cannula. Insertion of the device into the introducer desirably causes a one-way coupling operable to force removal of the introducer and device as a single assembly. Installation of certain devices into certain introducers forms an electrical connection between an electrode carried by the introducer and system electronics. Desirably, the introducer provides a funnel-like structure operable to guide a device's probe tip into reception in the introducer's cannula.

Abstract: A grit classifier of the type used in a variety of industrial applications to separate grit or particulate matter from a feed slurry is disclosed, the grit classifier being unitarily-formed in one or two pieces of moldable plastic or plastic-like material which renders the grit classifier more easily and cost-effectively manufactured. The grit classifier of the present invention is also advantageously easy to transport to a site, thereby further reducing the costs of use. Also disclosed is an auger beating assembly for use in the unitarily-formed grit classifier tank of the present invention which is simply structured and adaptable to any screw auger type or size.
