A tool for the primary shaping of a housing for a sensor which is designed to capture, via a sensing element, a physical area that is dependent on a variable to be measured, and to emit an electrical output signal on the basis of the captured physical area, including: a mold cavity for receiving a material that molds the housing, and the sensing element, and a box having a wall that bounds the mold cavity, wherein at least a part of the wall that bounds the mold cavity is mounted in a displaceable manner.

The present invention is directed to a method for additively fabricating a solid object from a series of components. The method utilizes additive fabrication with a programmed computer operating a machine to produce a solid object based on a three dimensional, computerized rendering of the solid object. Each component is produced from one or more molds which are filled with a fluid material that solidifies into a component that attaches to a previously manufactured component by way of the same process.

A lens comprises an internal cavity structure formed by dissolution of a soluble insert material. The internal soluble material may dissolve through a body of a lens such as a contact lens in order to form the cavity within the contact lens. The cavity within the lens can be shaped in many ways, and corresponds to the shape of the dissolved material, such that many internal cavity shapes can be readily fabricated within the contact lens. The insert can be placed in a mold with a pre-polymer material, and the pre-polymer material cured with the insert placed in the mold to form the lens body. The polymerized polymer may comprise a low expansion polymer in order to inhibit expansion of the lens when hydrated. The polymer may comprise a hydrogel when hydrated. The soft contact lens material comprises a sufficient amount of cross-linking to provide structure to the lens and shape the cavity.

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.

A method of producing a transdermal absorption sheet includes a preparatory step of forming the sheet portion in advance by drying and solidifying a base solution in a thin film state, a drug solution arrangement step of arranging a drug solution on a surface of a mold having needle-like recessed portions, a drug solution filling step of filling the needle-like recessed portions with the drug solution while pressingly expanding the drug solution on the surface of the mold by pressing the drug solution on the surface of the mold to the surface of the mold with the sheet portion, a drying step of drying an undried drug solution filling the needle-like recessed portions with the sheet portion to form needle-like protruding portions on a lower surface of the sheet portion, and a peeling-off step of peeling off the sheet portion and the needle-like protruding portions from the mold.

The invention provides a method for producing embedded contact lenses involving steps of use of a set of 3 mold halves in two-curing steps. One of the 3 mold halves have been used twice, the first time for molding an insert and the second time for molding the embedded hydrogel contact lens. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area of its molding surface having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adhered to the twice-used mold half. The method also comprises a step of forming a reactive polysiloxane coating that is covalently attached onto the back or front surface of a molded insert adhered on the twice-used mold half before molding the embedded contact lens in the 2.sup.nd curing step.

The invention provides a method for producing embedded diffractive contact lenses involving use of a mold set in two-curing steps. The mold set consists of three mold halves, one of which is used twice, the first time for molding a diffractive insert and the second time for an embedded contact lens with the molded diffractive insert embedded therein. The twice-used mold half has been treated with a corona plasma or a vacuum UV in a central circular area having a diameter equal to or smaller than the diameter of the insert to ensure that the molded insert consistently adheres to the twice-used mold half, even though the other mating insert mold half for molding the diffractive insert has a great tendency to bind strongly the molded insert due to the diffractive structure on its molding surface.

The invention provides a method for producing embedded contact lenses involving a mold set in a two-curing-step process and a fast-curing SiHy lens formulation. The mold set consists of three mold halves, one of which is used twice, the first time for molding an insert from an insert-forming composition and the second time for an embedded contact lens with the molded insert embedded therein from the fast curing SiHy lens formulation that comprises a N,N-dialkylacrylamide, a hydrophilic (meth)acrylamido monomer, and a polysiloxane vinylic crosslinker and being free of any siloxane-containing vinylic monomer.

The invention provides a method for producing delamination-resistant embedded contact lenses involving use of a mold set in two-curing steps and a special lens-forming composition for forming a bulk hydrogel material for embedding a crosslinked polymeric insert. The mold set consists of three mold halves, one of which is used twice, the first time for molding an insert from an insert-forming composition and the second time for an embedded contact lens with the molded insert embedded therein from the special lens-forming composition that a vinylic crosslinking agent and or organic solvent both of which independent of each other can swell an insert by a moderate swelling degree. The resultant embedded hydrogel contact lenses can be free of deformation and delamination.
