The multifunctional pocket knife (1) is composed of a handle (2) formed by two joined-together flanks (3, 3′) that provide at least one stowage space (4) for tools that each pivot about link pins (5, 5′) arranged at each end of the handle (2). It is characterized in that it comprises a planar tick-removal instrument (6) that pivots about one of said link pins (5, 5′) and that extends along the longitudinal axis of the pocket knife. Tick-removal instrument (6) designed to be incorporated into a multifunctional pocket knife (1).

The present disclosure relates to cantilevered imaging modality wearable optical systems that provide for optimal ergonomics coupled with vision enhancement and vision magnification. Methods of use, devices, and kits are also contemplated.

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 portable folding virtual reality device having a cover formed horizontally; a mounting case which is provided on a front of the cover and on which an image device such as a smart phone is mounted; a lens plate provided with a magnifying lens at a rear of the cover; and a band which is connected to both ends of the lens plate and through which the device is mounted to a head of a user. The mounting case and the lens plate are arranged to form up and downward at a right angle and to rotate by the cover and a front and rear hinges. A supporting plate that rotates left and rightward with respect to a central line of the cover is provided, and the interval between the front hinge and the rear hinge is identical to the focal distance of the left and right magnifying lens.

A magnifying device for a mobile device is a case, for inserting a cellular phone into, that has a see-through front cover with a magnifying screen for enlarging the print on the screen of the cellular phone. A pocket on the back cover holds a thin magnifier for using to enlarge the minute print often used in cellular phone menus.

Pairs of foldable glasses are provided. The pair of foldable glasses includes two lenses surrounded by a frame, the two lenses having a first side and a second side, the first side facing outwards and the second side facing the wearer, a hinged bridge for connecting the lenses together and permitting the lenses to fold together, and two temple pieces extending from an outer edge of the frame with a hinged connection between each of the temple pieces and the outer edge of the frame enabling the two temple pieces to fold inwards or forwards, wherein the two temple pieces have a hinged joint permitting a rear section of the temple pieces to fold forwards underneath the temple pieces, wherein the rear sections each include a loop configured to enable the pair of foldable glasses to be secured to a separate device.

A microscope apparatus includes a sample carrying module, a light source module and a lens module. The sample carrying module includes an adhesive element and a body having a light-transmission region and a sample viewing surface. The adhesive element is detachably adhered to the body, and at least partially covers the light-transmission region, such that the adhesive element is disposed adjacent to the sample viewing surface. The light source module is detachably disposed at a side of the body, and includes a base and a light source. The base has an aperture, and the sample carrying module is detachably disposed at a side of the aperture. The light source is disposed in the base. The lens module includes at least one lens, which is detachably disposed at one side of the sample carrying module and substantially focuses at the sample viewing surface, and corresponds to the light source module.

A portable microscope apparatus operated with an image capture device includes a sample carrying module, a lens module, a first polarizer and a second polarizer. The sample carrying module includes a transparent carrier and a sample adhesive element including a substrate and a glue layer. The substrate has a concave portion and an extending portion. The concave portion is adjacently connected to the extending portion to form a first surface. The glue layer is at least partially disposed on the first surface and in an integrated form with the substrate. The lens module is detachably connected to the image capture device, and disposed between the sample carrying module and the image capture device. The first polarizer is disposed on an optical path on one side of the sample carrying module. The second polarizer is disposed on the optical path on the other side of the sample carrying module.

Functional optical equipment such as lenses, prisms, optical flats, and color filters are made from hard candy, resulting in working optics that can be treated as either experimental equipment or confectionaries. These hard candy optics are manufactured by an extremely precise casting process, which avoids the need to polish or reshape the candy after casting and allows for the production of a wider selection of optical equipment. This process also allows the inclusion of features that expand the applications of the hard candy optics, but are not themselves optically functional.

A reflecting microscope module cooperating with an image capturing module includes a housing, a lens and a sample adhesive substance. The housing has a sample inspecting surface located on one side of the housing opposite to the image capturing module. The lens is disposed in the housing and the sample adhesive substance is detachably disposed on a bottom of the housing. The sample adhesive substance adjacently connected to the sample inspecting surface includes a substrate and a glue layer. The glue layer is integrally combined with the substrate to form one piece. A reflecting microscope device is also disclosed.
