Methods for manufacturing an item that include obtaining a component support assembly having at least a first component on a top surface of a planar support member, and placing a frame onto the planar support member's top surface or around the planar support member such that the frame surrounds the first component. The frame has at least one side member, and an inner surface of the side member defines a frame cavity. The methods may also include depositing a second component material into the frame cavity and onto the component support assembly, and allowing the second component material to harden to form a second component that is secured to the first component and the planar support member's top surface. The methods may include removing the frame from the unfinished item, and removing the planar support member from the first and second components to reveal a bottom surface of the item.

Embodiments of wearable electronic devices, components thereof, and related systems and techniques are disclosed herein. For example, a wearable electronic device may include a wearable support structure having a first surface and a second surface; a first electrode located at the first surface, wherein, when the wearable electronic device is worn by a user on a portion of the user's body, the first electrode is arranged to contact the user's skin in the portion of the user's body; a second electrode located at the second surface, wherein, when the wearable electronic device is worn by a user on the portion of the user's body, the second electrode is arranged to not contact the user's skin in the portion of the user's body; and a resistance switch having first and second input terminals coupled to the first and second electrodes, respectively. Other embodiments may be disclosed and/or claimed.

The present embodiments generally describe a monolithic, e.g., integral, box unit and methods of manufacturing monolithic box units. The monolithic box unit has a ring portion and a body portion, both of which are molded and set simultaneously. The method proceeds with filling a female oriented cavity with a Polymer mixture, allowing both the ring portion and body portion to fill and cure at the same time. Once ejected from the cavity, the entire unit can be trimmed and then add hardware and cover to complete the box.

Syntactic polyurethane elastomers are made using a non-mercury catalyst. The elastomer is made from a reaction mixture containing a polyether polyol having a low amount of terminal unsaturation, a chain extender, a polyisocyanate and microspheres. The elastomer adheres well to itself, which makes it very useful as thermal insulation for pipelines and other structures that have a complex geometry.

An optical component has a small-volume section and a large-volume section, wherein said optical component is a single-piece injection-molded component with the exception of one region in the large-volume section, said component being supplemented, in the region in the large-volume section, by an add-on to the optical component.

A device for producing branched structures is provided which includes an enclosed cell enclosed by two sheets with a port in at least one of the sheets and an injection device connected to the port. The enclosed cell may also include a boundary joining the two sheets. A method is also provided for producing branched structures, wherein fluids of differing viscosities are injected into an enclosed cell and the fluid of lower viscosity branches into the fluid of higher viscosity. The branching of the fluid can be modified using contoured or textured surfaces of the enclosed cell, injecting or evacuating the fluids during branch formation, or impressing a stencil or stamp over a surface of the enclosed cell.

A moisture-tight, re-sealable container is disclosed having a lid and body. The lid and body have a non-round seal that is substantially moisture tight when the lid is seated on the body, admitting less than 1000 micrograms per day of water to a package. A reinforcement stiffens or reinforces at least a portion of the seal against inward deflection along an axis defined by the minor diameter when the lid is seated on the body. Optionally the reinforcement is at least one spline subdividing the reservoir. A method of making dispensers for objects of varying length to customize particular dispensers to dispense such objects of a particular length is also disclosed.

In certain exemplary embodiments of the present invention, three-dimensional micro-mechanical devices and/or micro-structures can be made using a production casting process. As part of this process, an intermediate mold can be made from or derived from a precision stack lamination and used to fabricate the devices and/or structures. Further, the micro-devices and/or micro-structures can be fabricated on planar or nonplanar surfaces through use of a series of production casting processes and intermediate molds. The use of precision stack lamination can allow the fabrication of high aspect ratio structures. Moreover, via certain molding and/or casting materials, molds having cavities with protruding undercuts also can be fabricated.

A device for manufacturing a support for the human body, of the type including a mold including a lower female portion and an upper male portion capable of being coupled with one another so as to define at least one cavity between them inside which at least one material in the fluid state intended to make the support can be poured. The female portion of the mold includes at least one mobile block including at least two different surfaces suitable for making up respective different bottoms of said cavity for separate pouring steps of at least one material in the fluid state foreseen in the support. A process for manufacturing a support for the human body is moreover presented.

An explosive device, such as a missile, artillery round, aerial bomb, mortar round, or mine, that utilizes a wall structure that upon detonation provides displacement of smaller fragments interstitially between larger fragments. The displacement of the smaller fragments into the interstitial spaces at detonation creates an expanding fragmentation curtain that momentarily contains expanding gases to increase the impulse pressure of the explosion, thereby increasing the kinetic energy imparted to the fragments. In some embodiments, the wall structure includes ordered layers of preformed metal fragments encased in binder material that suspends the fragments in a desired arrangement prior to detonation.
