Abstract: A compact self-contained lighting system combining efficient LEDs with heat dissipating heat sinks, wherein the heat sinks are electrically connected to and provide power flow to the LEDs.

Abstract: A cautery tool is provided with a compact, lightweight, user-directable lighting facility that can be powered by either a shared external power source from which a power flow is shared continuously with the cautery function, by a supplemental self-contained power cell that may be recharged by a portion of the external power for use independently of the cautery function, or by sharing of a self-contained power cell by the cautery and the lighting functions. Waste heat generated during exercise of the lighting function is continuously removed from a light-emitting element by electrical conductors also serving as heat transfer conduits.

Abstract: A compact, self-contained lighting system is attachable to a surgical tool to enable a user to selectively direct light at a site where the tool is to be applied. The system has a power unit that may contain rechargeable power cells, a malleable electrical connection element, and a light-emitting element powered thereby to emit high intensity white light, preferably from an LED. The system ensures against tissue damage due to inadvertent overheating by continuously removing byproduct heat from the light-emitting element, via the connection element, to the power unit with portions of each of these components serving as respective heat sinks and/or as thermal conduits to facilitate this process. The removed heat is dissipated to the ambient atmosphere, the surgical tool and even the user, and permits safe prolonged operations in confined regions of a patient's body.

Abstract: A scoop assembly capable of being lifted through a granular material to a headspace of an upright container from a location in the container below the headspace when the granular material is fluidized by shaking the container along a substantially vertical axis. A scoop assembly has a handle portion connected to a measuring portion. The measuring portion has a cavity which is covered by a removable cover which prevents granular material entering the cavity before the scoop assembly is lifted into the headspace. The scoop assembly has an outer shape which is streamlined to enhance lifting speed.
