A Near-Eye-Display (NED) device having a housing shell that is integrated with molded boss clusters for precision mounting of hardware components. The techniques disclosed herein include forming a housing shell directly over one or more pre-molded boss clusters that have been inserted into cavities of a housing shell mold core. For example, with the pre-molded boss clusters already inserted into the cavities, a selected housing shell material such as a thermosetting epoxy resin impregnated carbon fiber reinforced (CFRP) fabric may be thermal compression molded over the housing shell mold core. Individual ones of the pre-molded boss clusters include one or more three-dimensional (3D) bosses for mounting various hardware components of the NED device. The bosses may protrude from an inner surface of the housing shell and may provide interior mounting features without affecting the appearance of the outer surface of the housing shell.

A method of making an integrated depth sensor window lens, such as for an augmented reality (AR) head set, the depth sensor window lens comprising a sensor lens and an illuminator lens separated by an opaque dam. The method uses a two-shot injection molding process, a first shot comprising an optically clear polymeric material to form the sensor lens and the illuminator lens and the second shot comprising an opaque polymeric material to form the separator of the two.

A tool (10) far assisting an optician in removing lenses (42) from or inserting lenses into eyeglass frames (44) includes an elongated block of substantially rigid material (12) having a forward working end (14) and a rearward free end (16) Opposite the working end the portion between the free end and the working end functioning as a handle to be grasped by a person's hand. A first recess (24) is formed in the bottom surface (22) of the block along with a first curved surface (26) and a first hook (28). The first curved surface includes a rearward lacing pointed edge (27). Similarly, a second recess (36) is formed in the top surface (20) of The block along with a second curved surface (38) and a second hook (40). The hooks (28, 40) are adapted to rest against the edge (46) of the frame (44) as the pointed edge (27) or the second curved surface (38) presses the lens (42) out of or into the frame (44) as the free end (16) of the tool is rotated.

An article includes a hollow enclosure defining a void. The void has a first section and a second section separate from the first section. An electronic component is housed in the first section and the second section of the void. A low pressure mold material is molded into the first section of the void and cured around a first segment of the electronic component to encapsulate the first segment of the electronic component. A support seal is inserted into the second section of the void adjacent a second segment of the electronic component. The support seal defines a sealing barrier on one side of the low pressure mold material that limits the flow of low pressure mold material out of the first section of the void.

A method is described for making frame components for spectacles, including: superimposing within a first mold, in the following order, at least a first film of plastic material, at least one semi-finished element pre-impregnated with resin, and at least a second film of plastic material; closing and heating the first mold, the temperature and pressure being applied and maintained until the resin is fully polymerized, in order to produce an intermediate component containing the semi-finished product); opening the first mold and extracting the intermediate component from the first mold. The method also includes: placing the intermediate component in a second mold; closing the second mold and forming a layer of polymer material on the intermediate component, resulting in mutual adhesion; opening the second mold and extracting an article produced by the molding step in the second mold and cutting the article to define the final profile of the component.

An oxygen delivery apparatus wearable by user includes a frame including nose pads connected to a bridge portion, an oxygen inlet defined by one of the nose pads, an oxygen inlet defined by the frame, and a hollow channel contained by the frame. The oxygen inlet and oxygen outlet are in fluid communication via the hollow channel. The frame can be formed as a monolithic structure using additive manufacturing. A nasal prong can be connected to the oxygen outlet such that a prong outlet of the prong is in fluid communication with the hollow channel. The prong outlet is positioned within a nostril of the user during use of the apparatus. A method of fabricating the frame includes obtaining measurement information for at least one of a head feature or facial characteristic of the user and generating a digital model of the oxygen delivery apparatus using the measurement information.

The present invention relates to a method for manufacturing a spectacle frame adapted to a spectacle wearer, particularly by means of 3D printing or other additive manufacturing techniques. The present invention provides for this purpose a method comprising the steps of providing a virtual 3D model of a spectacle frame; providing a virtual 3D model of the head of the spectacle wearer which comprises at least a part of the head of the spectacle wearer which is in contact with the spectacle frame when the spectacle frame is being worn; positioning the 3D model of the spectacle frame relative to the 3D model of the head in a virtual environment so that the 3D model of the head intersects the 3D model of the spectacle frame where said part of the head of the spectacle wearer is in contact with the spectacle frame when the spectacle frame is being worn; cutting a portion out of the 3D model of the spectacle frame along the intersecting plane of the 3D model of the spectacle frame and the 3D model of the head; and manufacturing at least a part of the spectacle frame on the basis of the part of the 3D model of the spectacle frame from which the portion has been cut.

Some embodiments provide a lens including a lens body and an optical filter configured to attenuate visible light in certain spectral bands. At least some of the spectral bands can include spectral features that tend to substantially increase the colorfulness, clarity, and/or vividness of a scene. In certain embodiments, eyewear incorporates an optical filter that enhances chroma within one or more spectral bands. In some embodiments, a wearer of the eyewear can perceive the increase in chroma when viewing at least certain types of scenes.

According to examples, a lens configuration for a head-mounted display (HMD) device may include a base platform made from glass or plastic, an antenna layer deposited onto the base platform, an optical polymer film deposited onto the antenna layer, and a lens layer deposited onto the optical polymer film through a 3D printing technique. The antenna layer may include a transparent antenna embedded into or deposited onto a transparent layer. The lens layer may be 3D printed as multiple partial layers to have a shape that matches a prescription for the lens layer.
