DETAILED DESCRIPTION
A description of example embodiments of the invention follows.
FIGS. 1A-5C depict one embodiment of the present invention wearable electronic eyewear display 12. The eyewear display 12 can include a head band member 18 with two side portions 18a and 18b, for being worn in a generally or close to horizontal or level orientation on a user's head 10 above the ears 8. The side portions 18a and 18b can each include ear capture or rest structures, such as curved concave shaped recesses, necks, indentations, arcs, arches, pockets or notches 26, for capturing, engaging or resting upon the top portions of the ears 8 that join to the head 10, and preventing forward/backward and side to side movement. A display arm 16 having an active display viewing device 14 can be rotatably or movably coupled to an outer side of one side portion 18b about a rotatable joint 22 along a lateral, horizontal or side axis 22a, and can provide adjustment for viewing position. The active display device 14 can be extended forwardly from the side portion 18b by the display arm 16, for positioning in front of one eye 9 of the user 10, such as the left eye, as shown. The display arm 16 can have a generally straight proximal portion 16a for extending forwardly relative to the user's head 10, and a bent, curved or angled distal portion 16b for extending or positioning the active display device 14 across or in front of, near or adjacent one eye 9, for viewing. If desired, the active display device 14 can be mounted to the display arm 16 by at least one movable joint.
Referring to FIGS. 3 and 4A-4E, speakers 28 can be positioned in the forward end 30 of one or both side portions 18a and 18b, in front of the ears 8 for providing the user with sound or audio. A camera 24 can be positioned along an outer side of the display arm 16, such as on the generally straight portion 16a. The camera 24 can have a narrow or thin elongate ridge 24a extending forwardly along portion 16a, and can aim the camera lens 24b generally in the direction that the user's eye 9 is looking or head 10 is turned. The active display device 14 can have a viewing port, part, window or screen 14a, which the user can view images from. The active display device 14 can be compact in size and can include miniature or compact viewing optics and an active matrix electronic display within a housing. In one embodiment, the active display device 14 can be a small, narrow, compact Olympus active display device, but other suitable active display devices as known in the art can also be used. The active display device 14 can include an active matrix display or microdisplay, and optics, as known in the art. Some embodiments can project images into the user's eye 9. Electrical or electronic port(s) 32 can be located on at least one side portion 18a or 18b for electrically connecting to desired electrical devices, and can include a USB port with a protective door. More than one port 32 and type of port can be provided. The port 32 can allow devices such as a computer, phone, video player, etc. to be connected to the eyewear display 12 to provide images, video and audio to the user, or to allow the user or eyewear display 12 to communicate with the devices.
The head band member 18 and the display arm 16 can be made of suitable plastics, composites or metals, or combinations thereof, and can be slender or slim, to be light weight and closely fit the user's head 10. The head band member 18 can have a height H1 in the vertical direction that is considerably greater than the thickness T1 (FIG. 4) in the lateral direction to provide strength in the vertical direction and can allow resilient bending or deflection in the outward lateral direction to adjust to different head widths. The forward ends 30 of the side portions 18a and 18b can angle or curve laterally inwardly toward each other and can provide resilient lateral engagement against the sides of the user's head 10. This lateral inward curve or angle of the ends 30 can cause portion 16a of the display arm 16 to angle slightly inwardly toward eye 9 and relative to the axis of symmetry S. The height H1 of the head band member 18, the height H2 of the display arm 16 in the vertical direction, and the depth of the notches 26, can be sized so that when the eyewear display 12 is worn over the ears 8, the central axis X of the eyewear display 12 can be generally aligned at the level of or inline with the user's eye 9 (FIG. 1). The axis X can have a slight downward angle as shown, but can be considered generally or close to horizontal or level. The head band member 18 and the side portions 18a and 18b can also be symmetrically laterally curved relative to vertical axis V (FIGS. 1C, 1D and 4A), for extending and curving around the rear of the head 10, and conforming to the user's head 10.
The head band member 18 can have a pair of ear capture structure notches 26 on both the narrow symmetrical upper or top, and lower or bottom surfaces or edges, near the ends 30 so that the two side portions 18a and 18b collectively have two pairs of laterally spaced apart outwardly facing edge notches 26 located on the edges of adjacent side portions 18a and 18b, one pair facing upwardly and one pair facing in the opposing direction downwardly. Each individual side portion 18a and 18b can also be considered to have one pair of opposing notches 26 vertically aligned with each other, one notch 26 facing outwardly upwardly and the other facing outwardly downwardly on the same side portion. This can allow the eyewear display 12 to be flipped one way or another, right/left, top/bottom, or oriented, to position the display arm 16 and active display device 14 near or in front of either the left eye or the right eye, while being able to engage the top portion of the ears 8 with one of the two pairs of notches 26 regardless of which eye 9 the active display device 14 is in front of. The top and bottom edges or surfaces of the head band member 18 are identical and symmetrical so that the eyewear display 12 can be selectively positioned sequentially or periodically ambidextrously in a reversible or mirror image manner. One pair of notches 26, for example shown on the bottom, can be associated with engaging the ears 8 with the active display device 14 being in front of the left eye, and the other or opposite side of notches 26, for example shown on the top, is associated with engaging the ears 8 with the active display device 14 being in front of the right eye when flipped to be on the bottom. Each notch 26 can include padding or a padding member 26a which can be located in, on or covering, the curved shape of the notch 26 for user comfort.
The height H1 of the head band member 18 can gradually increase, moving from the center of the rear forwardly towards the notches 26 at an angle or curve, or combinations thereof, symmetrically on the top or bottom edges, which can provide increased height H1 for allowing the notches 26 to be formed therein. The notches 26 in the upper and lower edges then provide a more rapid curved symmetrical decrease and increase in height H1 moving along the length of the notches 26 from rearward to forward ends. The height H1 on the other or forward side of the notches 26 can then gradually decrease moving toward the forward ends 30 at an angle or curve, or combinations thereof, symmetrically on the top and bottom edges. The display arm 16 has a height H2 in the vertical direction positioned at the end 30 of side portion 18b that is greater than the lateral thickness T2, and the height H2 can decrease moving towards the distal end to the active display device 14 at an angle or curve, or combinations thereof, symmetrically on the top and bottom edges. The thickness T2 at the active display device 14 end can increase. This can provide a combination of strength in the vertical direction and environmental visibility in front of the user's eye 9. The display arm 16 can have a height H2 at joint 22 which is about the same as the height H1 at the forward end 30 of side portion 18b for a smooth looking transition between the two components. The gradual symmetrical increase in height H1 of the head band member 18 moving from the rear of the head band member 18 forward to the notches 26, the rapid curved symmetrical decrease in height H1 of the notches 26, and then the gradual symmetrical decrease in height of the head band member 18 away or forward from the notches 26, can provide a top/bottom and side to side symmetry of the head band member 18 that is both ambidextrous and pleasing in appearance. The symmetrical decrease in height H2 of the display arm 16 provides a visual extension of this symmetry on one side. From the side view, the head band member 18 with or without the display arm 16, can provide the appearance of a slim hour glass section with narrower ends. The side view appearance with the display arm 16 provides a longer pointed forward end, and without the display arm 16 provides a shorter pointed forward end, at the end of the hour glass. Joint 22 typically rotates or swings display arm 16 up and down in the direction of arrows B (FIG. 3), but in other embodiments, joint 22 can include a multidirectional function, such as a ball joint for allowing rotation and adjustment in other directions.
The side portions 18a and 18b can have identical or symmetrical inner 19 and outer 21 curved side or lateral surfaces or faces that extend vertically or relative to vertical axis V, with height H1, and face laterally or to the side curving around vertical axis V. The rear or proximal ends 23 of side portions 18a and 18b can be rotatably coupled or connected together at the center of the rear of the head band member 18 by a head band member rotatable joint 20. Referring to FIG. 5A-5C, the rotatable joint 20 can have or allow an axis of rotation 20a that is at an angle relative to the axis of symmetry S (FIG. 4) so that side portion 18a that is not attached to display arm 16 can rotate in the direction of arrow A, up or down, to rotate, pivot, fold and/or nest within side portion 18b to one side of the axis of symmetry S, where the outer curved surface 21 of side portion 18a is nested against or adjacent to the inner curved surface 19 of side portion 18b. The axis of symmetry S can extend between the unfolded side portions 18a and 18b from front to back. The display arm 16, that is attached to side portion 18b, can also be rotated, pivoted, folded and/or nested against, alongside or adjacent to the outer curved surface 21 of side portion 18b by rotating display arm 16 relative to side portion 18b with joint 22, about axis 22a in the direction of arrow B. The inner surface 17 of the display arm 16 can nest against, alongside or adjacent to the outer curved surface 21 of side portion 18b. The inner surface 17 can have a curve. This can allow the eyewear display 12 to be folded up into a small and compact manner with the side portions 18a and 18b, and display arm 16 being positioned against or adjacent to each other in a three curved layer nested configuration or structure, for storage or transportation, and can be a fraction of the size of the eyewear display 12 in it's unfolded state for use. The side portion 18a can form an inner curved nested layer, the side portion 18b can form an intermediate or middle curved nested layer, and the display arm 16 can form an outer nested layer, which can have a curve. The side portion 18a, and the display arm 16 are attached to and rotatably pivot from opposite ends of side portion 18b, forming a rotationally contractable and expandable arrangement, that can contract and expand in size both in width and length. In some embodiments, joint 20 can include a ball joint.
While this invention has been particularly shown and described with references to example embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention encompassed by the appended claims.
For example, although terms of orientation have been used, such as upper, lower, inner, outer, etc., this does not limit the orientation or construction of embodiments in the present invention. In some embodiments, the side portions 18a and 18b and the display arm 16 can be integrally formed together, and/or do not have to be connected together by movable or rotating joints.
