Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.

Embodiments of golf clubs with grooves and methods of manufacture thereof are described herein. In one embodiment of a golf club described herein, the golf club has a head with a body. The body has a strike face with channels and at least one insert located within at least one of the channels. At least one of the channels comprises a single groove, and the insert forms at least a portion of the single groove. At least one of the channels comprises an opening on the strike face that is narrower than a bottom of the at least one of the channels. Other embodiments and related methods are also disclosed herein.

The invention relates to a tool for hot-tanning and/or press hardening of a sheet metal material, this tool having a plurality of cooling devices through which a coolant can flow, in order thus to be able to actively cool at least regions of the effective tool surfaces which come into contact with the sheet metal material. According to the invention, at least one cooling device comprises a shell element having an effective tool surface, wherein this shell element has, on its rear side facing away from the effective tool surface, a plurality of separate cooling chambers, through which a coolant can flow, and arranged in each of these cooling chambers is at least one flow guiding element for the coolant. The invention also relates to a method for producing such a cooling device for this tool.

Methods for manufacturing a metal foam and a metal foam reinforced back plate may be used to provide high-strength and low weight structural elements in portable information handling systems. A method for manufacturing a metal foam may include selectively adding iridium oxide and ceramic particulate to a light-metal allow to create desired mechanical properties of the metal foam.

The invention provides an endoscope having a lens holder, wherein the lens holder includes a body containing a sintered feedstock and machined surfaces. The invention also provides a method of manufacturing the endoscope which includes the steps of molding a metal blank by a MIM process, wherein the metal blank is near net shape and has a sprue, a post, and optionally an outer shell, machining the inner surfaces and then the outer surfaces of the metal blank to form a lens holder, installing a lens in the lens holder, and assembling the lens holder having the lens into the endoscope.

According to the method of stripping a portion of a wire of the invention, the insulated wire including the wire core are first flattened before the insulation is stripped away. The flattening eases the stripping as the insulation is partially cracked and dissociated of the wire core, and the stripping is more efficiently applied on a flat surface. A wire stripping machine and a transponder antenna with stripped portions are also claim as being part of the invention.

The present invention relates generally to forming a threaded neck in a metal bottle manufactured by a process known as impact extrusion. More specifically, the present invention relates to methods, apparatus and alloy compositions used in the impact extrusion manufacturing of containers and other articles with sufficient strength characteristics to allow threading the container necks to receive a threaded closure on the threaded neck.

Disclosed herein is a nickel-titanium alloy comprising nickel, titanium, and at least one rare earth element. The nickel-titanium alloy comprises from about 34 at. % to about 60 at. % nickel, from about 34 at. % to about 60 at. % titanium, and from about 0.1 at. % to about 15 at. % at least one rare earth element. The nickel-titanium alloy may further include one or more additional alloying elements. In addition to radiopacity, the nickel-titanium alloy preferably exhibits superelastic or shape memory behavior. Medical devices comprising the nickel-titanium alloy and a method of making them are also disclosed.
