A watch stand configured to receive a smart watch including a face. The watch stand includes a receptacle configured to temporarily receive the smart watch within it with the smart watch positioned on edge and a body configured to magnify the face of the smart watch when the smart watch is viewed through the body.

Proposed is a lens system capable of providing, to a user, a high-definition image in which generation of concentric circles is reduced. The lens system has one or more Fresnel lenses. A lens surface of each of the Fresnel lenses has a plurality of grooves that is concentrically formed. Both a pitch which is the distance between two adjacent grooves and the depth of each of the plurality of grooves vary with the distance from an optical axis that passes through the center of the lens system.

Holographic energy directing systems may include a waveguide array and a relay element. Disclosed calibration approaches allows for mapping of energy locations and mapping of energy locations to angular direction of energy as defined in a four-dimensional plenopic system. Distortions due to the waveguide array and relay element may also be compensated.

A lens unit includes a first lens and a second lens. The first lens is a Fresnel lens that has a first lens surface having a Fresnel structure on the second lens side, and has a positive refractive power. The second lens is a Fresnel lens that has a second lens surface having a Fresnel structure on the first lens side, and has a positive refractive power.

Disclosed are high-density energy directing devices and systems thereof for two-dimensional, stereoscopic, light field and holographic head-mounted displays. In general, the head-mounted display system includes one or more energy devices and one or more energy relay elements, each energy relay element having a first surface and a second surface. The first surface is disposed in energy propagation paths of the one or more energy devices and the second surface of each of the one or more energy relay elements is arranged to form a singular seamless energy surface. A separation between edges of any two adjacent second surfaces is less than a minimum perceptible contour as defined by the visual acuity of a human eye having better than 20/40 vision at a distance from the singular seamless energy surface, the distance being greater than the lesser of: half of a height of the singular seamless energy surface, or half of a width of the singular seamless energy surface.

The invention relates to a visual aid apparatus (1), in particular an optically or electronically magnifying visual aid apparatus (1), comprising at least one electrical or electronic functional component (2) that consumes electrical energy in at least one operating state, at least one rechargeable electrical energy store (3) that is assigned to the at least one electrical or electronic functional component (2), at least one inductive element (4) that is assigned to the at least one electrical energy store (3) and configured to supply the at least one electrical energy store (3) with electrical energy by way of an inductive interaction with at least one further inductive element (5).

The present invention relates to a new integrated system combining hardware and software together. It helps solving some existing problems and makes matters easier for the users of such new technology. This new technology enables users to dispense of some tools, like selfie stick, altogether with other tools used all the time. This new technique is not limited to specific age bracket, as it suits men, women and children. It enables user to clearly see numbers and messages at sunlight, via a novel software operable with all languages of computer and mobile (Windows, Android, Mac, IOS and others), in addition to a hardware.

A drinkware product includes a vessel container and a base having upper and lower surfaces and a periphery, wherein the base includes a transparent section extending through the base from the upper surface to the lower surface and having an optical surface providing a predetermined degree of magnification when viewed through the transparent section from the upper surface of the base. The optical surface providing a predetermined degree of magnification is positioned to provide at least one focal point under the base positioned between the periphery of the base and a central location of the base when viewed through the transparent section from the upper surface of the base. The vessel container may be formed by a sidewall extending up from the base at the periphery of the base, or may be an upper portion of a stemware with a stem extending between the base and upper portion. An existing product mold may be modified by either adding material to the mold or removing material from the mold to form a modified mold surface which will impart an optical surface to the base of a stemware or other drinkware product formed with the modified mold.

Disclosed are transparent energy relay waveguide systems for the superimposition of holographic opacity modulation states for holographic, light field, virtual, augmented and mixed reality applications. The light field system may comprise one or more energy waveguide relay systems with one or more energy modulation elements, each energy modulation element configured to modulate energy passing therethrough, whereby the energy passing therethrough may be directed according to 4D plenoptic functions or inverses thereof.

A smart phone magnifier assembly for magnifying imagery displayed on a smart phone includes a magnifying screen that has a width ranging between approximately 3.0 inches and 5.0 inches and a length ranging between approximately 5.0 inches and 8.0 inches. In this way the magnifying screen can fit on a screen of a smart phone thereby facilitating the magnifying screen to magnify and thusly enhance visibility of imagery displayed on the screen. An adhesive layer is bonded to the magnifying screen for adhesively engaging the smart phone screen. Thus, the adhesive layer releasably retains the magnifying screen on the smart phone screen.
