Abstract: A chisel-type broadhead comprises a threaded ferrule laser welded to multiple blades. The blades are welded from both sides. The blades are welded to each other and to the ferrule. The ferrule and blades are configured to provide maximum impact strength to the broadhead. An optional feature enabling the broadhead ferrule threads to be tightened to the arrowshaft is provided. An improved method of welding the blades to the ferrule is provided.

Abstract: A system for installation onto automobiles that will detect forgotten or abandoned passengers and notify the driver by email, cell phone, car alarm, or other means and will allow relief or rescue of trapped passengers.
Abstract: A glide/burnish suspension assembly processes magnetic memory storage disks by “flying” a glide/burnish slider across the surface of a rotating disk. A glide/burnish suspension assembly as described herein includes mounting holes and a tooling hole that are compatible with existing Type-2/Type-4 glide/burnish testing fixtures. The glide/burnish suspension assembly includes a stainless steel loadbeam that is compatible with Type-8/Type-20 designs, i.e., the loadbeam is configured to provide the structural support and rigidity required for use with smaller glide/burnish sliders. In this respect, the loadbeam can accommodate 70%, 50%, 30%, and possibly smaller glide/burnish sliders. The glide/burnish suspension assembly facilitates the continued use of “older” Type-2/Type-4 fixtures to perform gliding and/or burnishing of disks using the “newer” Type-8/Type-20 loadbeams designed to support 30% sliders.
