A measurement instrument includes a display configured to display information; a display controller configured to control displaying of the information on the display; and a reflector configured to invert the information displayed on the display via specular reflection. Since the measurement instrument includes the reflector configured to invert the information displayed on the display via specular reflection, information can be seen via the reflector even when the information is difficult to read directly from the display. Thus, the measurement instrument can improve visibility of the information displayed on the display.

The ProJoe is a great improvement and a new method of cell phone projection. It is a two-part cardboard stand-alone (a lens holder and a cell phone holder or stand) or add-on to an existing VR viewer that allows smartphones to project still images or video onto a blank wall or screen. This improvement allows for the user to inexpensively transform their cell phone into a real projector.

A foldable light box, including fourth profiles. The fourth profiles are assembled into a frame structure through profile connectors. The inner side walls of the fourth profiles at the upper end and the lower end of the frame structure are connected with lamp bead profiles. The inner side walls of the lamp bead profiles are stuck with LED lamp bead parts through a thermally conductive adhesive. The folding function of the entire light box is achieved by the cooperation of the foldable mechanism and the meshing mechanism provided by the present utility model. As the size is reduced, the light box is more convenient to place and transport, needs less transportation cost and space, and is more convenient to carry and display.

A magnifying display device, which includes a fixed base, an arm, a flip stand, a reflective module and a magnifying module, objects could be magnified several times and imaged far longer than several times of the object distance according to the principle of virtual imaging of concave mirrors, the magnified images users looked is imaged in a visual distance farther than two meters, to relieve visual fatigue caused by overuse of eyes at close range, to thereby slow down myopia progression.

An inflatable light box includes securing plates and panels in association with upper and lower interior connecting planks when coupled to a cylindrical barrel in which an inflatable airbag is disposed, and encompassed by a decorative cover, form a housing for an inflatable light apparatus.

An apparatus includes a frame, a screen supported by the frame for displaying an image; a first optical sensor for capturing an image, an extendable arm connected to the frame; and a second optical sensor connected to the arm for capturing an image. Such an apparatus can be used for capturing and displaying information for low vision persons.
