DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

InFIG.1an embodiment of a single unit in one piece comprising electronics1according to the present invention is shown. The single unit1is in one piece. The single unit1comprises components for making up smart glasses and is to be positioned in a pair of glasses2, seeFIG.4. The single unit1comprises at least one central processing unit (cpu), at least one sensor and at least one battery provided on a printed circuit board (pcb). Preferably, more sensors, a possible charging socket, such as a micro usb contact, possibly a switch and so on, may be provided in the single unit1.

The single unit1inFIG.1has a first end8and a portion10, which preferably is an encapsulated portion10comprising electronical components. Said encapsulated electronic portion is water and dust proof. Further the single unit1has a bridge portion12, preferably more or less directed transversally from the first portion10. It is preferred that the single unit1comprises a hinge11, which is provided between the first portion10, in the shown case the encapsulated electronics portion10, and the bridge portion12of the single unit1.

When positioned in a pair of glasses2, the single unit1reaches with its first end8and first portion10, at least from a first temple3up to a frame4, where the bridge portion12reaches past a first lens5positioned closest to the first temple3in the frame4at least up to a second lens6, positioned closest to a second temple7, with a second end9of the unit1, cfFIG.4.

In the shown embodiment ofFIG.1the pcb13is made in one piece reaching through also the hinge11. Preferably the hinge1is of the type shown in WO 2018/084772 (incorporated hereby) by the same proprietor, which minimises any mechanical wear of any connecting portion, for example the pcb, electrical or optical cables. The hinge11may have two axis connections, a first axis connection20apositioned closest to the frame4and a second axis connection20bpositioned closest to the temple3, and therebetween at least one central part21is arranged to let the at least one cable, pcb13or wire follow a thought neutral bending plane through the hinge11, seeFIG.2.

InFIG.2a further embodiment of the single unit1according to the present invention is shown. Also, this single unit1is in one piece and comprises components for making up smart glasses and is to be positioned in a pair of glasses2, seeFIG.4.

The single unit1inFIG.2has a first end8and a portion10, which preferably is an encapsulated portion10comprising electronical components. Said encapsulated electronic portion10is water and dust proof. Further the single unit1has a bridge portion12, preferably more or less directed transversally from the first portion10. A second portion14, also this portion is preferably encapsulated, is directed more or less transversally out from the bridge portion14, parallel with the first portion10.

It is preferred that the single unit1comprises a first hinge11, which is provided between the first portion10and the bridge portion12of the single unit1, and a second hinge11, which is provided between the bridge portion12and the second portion14of the single unit1.

When positioned in a pair of glasses2, the single unit1reaches with its first end8and first portion10, from the first temple3up to the frame4, where the bridge portion12reaches past the second lens6, positioned closest to the second temple7, and the second portion14reaches out into the second temple7with a second end9of the unit1, cfFIG.4.

The single unit1comprises at least one central processing unit (cpu), at least one sensor and at least one battery provided on a printed circuit board (pcb). Preferably, more sensors, a charging socket, such as a micro usb or usb C contact, possibly a switch and so on, may be provided in the single unit1. The different electronical components may be spread out in the two, first and second portions10,14, respectively.

According to one embodiment on of the portion may comprise a battery and the other may comprise most of the electronics, including the cpu. In the embodiment shown inFIG.2a micro usb contact15for the charging of the single unit1is provided in the second portion14, near the second end9. Further, a switch16is shown in the second portion14. At least one opening17may be present in the vicinity of at least one sensor arranged within the first10or second portion14.

InFIG.3the embodiment ofFIG.2is shown in the opposite direction. In this view the pcb13is shown along the whole bridge portion12and also through the first hinge11between the bridge portion12and the first portion10. Obviously, it is possible to arrange the pcb in other ways, such as on the other side of the bridge portion12or therein.

Also in the shown embodiment ofFIG.3the pcb13is preferably made in one piece reaching through the hinges11. Preferably the hinges11are of the type shown in WO 2018/084772 by the same proprietor, which minimises any mechanical wear of any connecting portion, for example the pcb, electrical or optical cables.

It I also conceivable to have smart glasses which is chargeable, specifically the at least one battery, by means of inductive charging where the single unit comprising electronics1also comprises at least a coil22provided around at least around one lens5. InFIG.4an embodiment is shown having a coil surrounding two lenses. This technology, which has been incorporated into the embodiment inFIG.4has been patented by the proprietor and more details can be found in WO 2018/169475 (hereby incorporated).

The coil could be provided by a wire or be a printed circuit in a structure, such as the pcb13shown inFIG.4. If the wire is round profile steel or copper wire it will form a substantial structural stability element for the glasses. If the coil22is a printed circuit the pcb13may have portions encircling at least one lens5. Preferably printed circuit is multilayer circuit. Depending on which type of substrate the printed circuit is printed on, it can be flexible or stiff.

InFIG.5a single unit comprising electronics1is positioned in a pair of glasses2. The single unit1can be provided in the glasses2by moulding or injection moulding by placing the single unit1in a mould before adding the polymer. According to another embodiment the frame4at least partly and, in this embodiment, both of the temples3,7are provided with recesses, which preferably correspond more or less to the size of the single unit1, so that the single unit1can be positioned in the recesses.

The single unit1may be attached in the pair of glasses by means of heating the material around the recesses so that the material fuses around the single unit, using adhesive, form fitting, riveting or screwing, or it is also possible to use one or more of the exemplified technics.

An embodiment of the single unit comprising electronics1is shown in a cross sectional view of the portion1to be positioned in a temple, seeFIG.6. A hard cover23comprises a form fitting19, and an elastic cover or embedding18comprising the electronics, such as the pcb13will fit in inside the form fitting19, for example an undercut shape.

Thus, the embedded electronics of the single unit1will stay put in the recess but will also be possible to take out, for example if updated electronics is available, and a wearer would like to keep the pair of glasses but have the updated single unit1it will possible to exchange the electronics of the single units1. Thus, the single unit1comprising the electronics embedded in elastic material kept inside the hard shell23of the single unit will be provided and sold in one piece to eye glasses manufacturers but with the advantage of an easy exchange in case an update of the electronics would be desirable.

As been described above many ways of incorporating the single unit1is possible. It is also conceivable to use different techniques for different parts, if for example the temples are of acetate and the frame of metal. In such a case it could be possible to make recesses in the temples for the first10and second portion14and then attach the bridge portion to the frame by means of screwing or gluing.

The single unit comprising electronics1could comprise supporting metal or be more flexible or be partly inflexible and partly flexible.
