An oral device may include a body. The body may have a main portion having an arch-shaped central portion, a first side portion extending from a first end of the central portion, and a second side portion extending from a second end of the central portion. The body may further include a first wedge portion provided on a bottom surface of the first side portion, and a second wedge portion provided on a bottom surface of the second side portion. Each of the first wedge portion and the second wedge portion may have a varying thickness.

The invention relates to a radiation-curable silicone composition for additive-manufacturing technology comprising mercapto-functional polyorganosiloxane(s) as Component A, organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties as Component B, photo-initiator(s) as Component C for initiating a curing reaction between Component A and Component B, dye(s) as Component D dissolved in mercapto-functional polyorganosiloxane(s) as Component E, the mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, wherein Component D is dissolved in Component E before Component D is combined with the other components of the radiation-curable silicone composition. The invention also relates to a process of producing a radiation-curable composition wherein the process comprises the steps of providing a solution of dye(s) in a composition comprising mercapto-functional polyorganosiloxane(s) having a fraction of (mercaptoalkyl)methylsiloxane units of at least 50 mol %, combining the solution containing the dye(s) dissolved in the mercapto-functional polyorganosiloxane(s) with mercapto-functional polyorganosiloxane(s), organosiloxane(s) with at least two aliphatic unsaturated carbon-carbon moieties, photo-initiator(s) for initiating a curing reaction between Component A and Component B, optionally filler(s), stabilizer(s) and additive(s).

An earplug assembly that includes an earplug. The assembly also includes a flexible cord extending from a first cord end to a second cord end and the first cord end fixed to the earplug, the flexible cord formed of copolymer comprising ethylene segments and vinyl acetate segments. The flexible cord has an elastic modulus of 10 MPa or greater at 100% elongation.

[Problem] To suppress changes in the recess depth and shape of a three-dimensional molded shape, and to form a uniform protective layer or ornamental layer along the surface of the molded shape. Also, to provide uniform application to the entire irregularly-formed surface and to suppress air pockets and partial defects of bonding. [Solution] In an adherend W having a three-dimensional molded portion in which a plurality of concavities and/or convexities are molded in a regular arrangement, a thermoplastic coating film larger than the area of an adhesion region is integrally adhered by a three dimensional decorative molding procedure in a predetermined adhesion region that includes the three-dimensional molded portion. The predetermined adhesion region includes all of the three-dimensional molded portion and covers more than half the perimeter of the adherend W incenter cross-sectional view.

A modular armor system configured to be readily attached and detached from a frame surrounding a window in a vehicle or other structure, such as a building. The modular armor system may be configured to provide any desired ballistics protection rating. In one embodiment, the modular armor system includes a ballistics-grade armor panel having an outer strike face and an inner surface opposite the outer strike face. The modular armor system also includes a fastener coupled to the ballistics-grade armor panel. The fastener is configured to detachably couple the ballistics-grade armor panel to the frame surrounding the window in the vehicle or other structure.

A polymer sheet adapted to attach to a material body such as a ceiling of a geological cavity and provide protective cover. The sheet comprises: a webbing portion defining a plurality of primary openings; and two margin portions extending along opposite edges of the sheet on either side of the webbing portion along a length of the sheet, each margin portion defining a plurality of secondary openings, wherein the margin portions are angled relative to the webbing portion.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

According to this procedure, these steps are made: a) immersing a shaped mold (4) in a dipping process in a liquid synthetic polyisoprene (IR) (synthetic latex), wherein the shaped mold (4) has previously been treated with coagulation agent (coagulants) or thermally treated, b) after the immersion, the synthetic polyisoprene layer is left on the shaped mold (4) and is freed from all salts with water, c) thereafter, the synthetic polyisoprene layer together with the shaped mold (4) is vulcanized in an oven, d) the synthetic polyisoprene layer is removed from the mold (4), e) the salts precipitated by the vulcanization on the synthetic polyisoprene molded body (11) are washed off with water and a chlorine-containing solution, f) the synthetic polyisoprene molded body (11) is halogenated to neutralize its pH and to increase its suppleness in contact with body skin with a halogenating solution, g) the synthetic polyisoprene molded body (11) is dried. The electro-protective gloves thus produced are much more comfortable to wear, provide better insulation, even with thinner wall thickness, and they are more durable.
