An electronic eyewear device having a thermal management device including a vapor chamber in the temples. The temples may have a sheet metal portion thermally connected to heat generating electronics, wherein the vapor chamber is thermally coupled to the sheet metal along a length thereof to disperse heat generated by the electronics. The sheet metal and the vapor chamber may be encompassed by a non-thermally conducting material, such as being over molded by a silicone material, to prevent user contact with the heated sheet metal and vapor chamber. The sheet metal and the vapor chamber are generally planar and lightweight, and they are bent to bias the temples against a user's head when worn to provide preloading.

A lens holding system for eyeglass frames having a pliable body with a lens opening for engagement of a lens therein and a circumferential edges configured to engage with a lens aperture of an eyewear frame to hold the lens operatively positioned therein. A front surface portion extending from the pliable body contacts a front surface of the eyeglass frame and is formed with a width narrower than a rear surface portion extending from the pliable body which contacts a rear facing surface of the eyewear frame. Significant comfort and performance enhancement is provided using a metal alloy frame in combination with polymeric temples.

A method of manufacturing is provided, including forming a metal frame of a head-mounted computing device shaped as a pair of eyeglasses. Forming the metal frame may include additively manufacturing the metal frame of the head-mounted computing device by performing laser sintering on aluminum powder or titanium powder. Forming the metal frame may further include removing an outer surface of the metal frame via a reductive process.

An eyewear frame having at least one frame component including a stimuli-responsive polymer is provided. The at least one frame component has a physical property which is reversibly changeable in response to a stimulus of non-thermal origin applied to the stimuli-responsive polymer. An eyewear including the eyewear frame, and a method of adjusting the eyewear frame are also provided.

A method for purifying powdered silicon carbide is in the form of a starting material to form a silicon carbide having a purity of at least 99.9%. This method has the following method steps: providing a starting material having a grain size of less than 100 μm and a silicon carbide content with at least 98% purity; and heating the starting material in a vacuum or oxygen-free atmosphere to a temperature above 1700° C. over a period of at least 8 minutes.

Disclosed is a method for manufacturing a three-dimensional article, including: a step of producing the article by an additive manufacturing technology, the article including at least two parts that face, at least partially, each other or that have edges facing, at least partially, each other; and a step of finishing of the article. According to the invention, the two parts are produced together with a temporary connection that links the two parts, and the method includes, after the step of finishing, a step of unlinking the temporary connection in order to separate the two parts.

A set of augmented reality (AR) or virtual reality (VR) glasses are disclosed. The glasses comprise a fiber reinforced structure. The fiber reinforced structure includes a continuous fiber component. The fiber reinforced structure also includes a thermoplastic material injection molded over the continuous fiber component, wherein the thermoplastic material surrounds the continuous fiber component. The glasses also comprise electronics that are coupled to the fiber reinforced structure, wherein the electronics are configured to facilitate presentment of imagery onto a lens of the glasses.

A component of a frame for eyeglasses includes a body made of composite material, the peculiarity of which relates to the body having at least one first region and at least two second regions. The first region includes a three-dimensional shape with at least two dimensions that are larger than the dimensions of the at least two second regions. Thus, the configuration defines, along the body, portions with different flexibilities.

An addressable vertical cavity surface emitting laser (VCSEL) array may generate structured light in dot patterns. The VCSEL array includes a plurality of traces that control different groups of VCSELs, such that each group of VCSELs may be individually controlled. The VCSEL groups are arranged such that they emit a dot pattern, and by modulating which groups of VCSELs are active a density of the dot pattern may be adjusted. The VCSEL array may be part of a depth projector that projects the dot pattern into a local area. A projection assembly may replicate the dot pattern in multiple tiles.

A sheet for manufacturing articles, particularly frames for glasses and the like, including at least one technical layer made of a thermoplastic material interposed between a first aesthetic layer and a second aesthetic layer, both made of a material such as fabric. A method for producing a sheet for manufacturing articles includes the steps of providing at least one technical layer made of a material such as thermoplastic polymers and at least two aesthetic layers made of a material such as fabric and associating the technical layer with the aesthetic layers. The layers are mutually compressed and then heated to obtain the sheet.
