One container system includes a transparent display, a projector for providing image data on the display, and a floor defining part of a watertight cavity. The display is non-perpendicularly angled from horizontal and has proximal and distal ends. And a closure device is provided for use with a watertight container. The closure device is configured to selectively seal an opening in the watertight container and includes coupling structure (a plug, a flange, and/or threading) for selectively coupling the closure device to the watertight container to seal the opening. The closure device further includes non-transitory computer memory, at least one sensor, and a processor in data communication with the memory and the at least one sensor.

A vehicle mountable holographic promoting system and method of use; the vehicle mountable holographic promoting system includes a body with at least one light, a mount, and a controller in communication with a software application and the body. The body is mountable to the vehicle via the mount. The mount is able to be removably attachable or otherwise secured to roof of a vehicle. The controller controls the body such that the body is able to visually promote via an image display at least one promotable item using the at least one light. The promotable item appearing to float on a plane above the vehicle.

A system for creating three-dimensional grass graphics can include a means for cutting grass with an adjustable cutting height, a chlorophyll-based agent for coloring grass, and at least one stencil. The chlorophyll-based agent can be non-detrimental to a health of the grass and can be available in multiple shades. The stencil can be securable to the grass and can define a graphic to be painted on the grass using the chlorophyll-based agent. The means for cutting the grass can be able to pass over and around the stencil without damaging the stencil. Application of different shades of the chlorophyll-based agent to varying heights of grass can produce a three-dimensional effect for the graphic when viewed.

The present disclosure relates to a rotary-type display apparatus using, for example, a light emitting diode (LED) which is a semiconductor light-emitting device, wherein the apparatus can be applied to technical fields related to display apparatuses. According to the present invention, a rotatory-type display apparatus using a light-emitting device comprises: a fixing part including a motor; a rotating part located on the fixing part and rotated by the motor; and a light source module which includes at least two rod-shaped panels coupled to the rotating part and arranged radially, and light-emitting device arrays respectively disposed on the panels in the longitudinal direction, wherein the height of the at least two panels from the rotating part may be different.

A light guide body in a display device includes a first incident surface on which an image light is incident, and a second emission surface from which the image light is emitted. The light guide body includes a second emission optical element that diffracts the image light to emit a portion of the image light at a predetermined emission angle every time the image light enters the second emission optical element from a predetermined direction. The image light is diverged by being emitted from the second emission optical element such that the predetermined emission angle varies in accordance with a location in one predetermined region included in a plurality of predetermined regions of the optical element. The degree of divergence varies between the one predetermined region and other predetermined region included in the plurality of predetermined regions in accordance with the location of the virtual image.

A display device includes a laser irradiation device and a control device. The laser irradiation device is configured to irradiate an irradiation point located at a display position in air, with a laser beam having a wavelength equal to or larger than 380 nm and equal to or smaller than 780 nm and produce plasma at the display position. The control device is configured to control intensity of the laser beam emitted from the at least one laser irradiation device so that a relationship between intensity of plasma light emitted from the plasma at the display position and intensity of scattered light produced from the laser beam and scattered by the plasma becomes a predetermined relationship to display a color pixel.

An approach for providing detailed product information at a product selection shelf location. The approach receives an indication from a sensor that a customer is in proximity to a product on a display shelf. The approach retrieves detailed information about the product from a product data storage location. The approach generates a formatted presentation of the detailed information. The approach displays the formatted presentation as a holographic image from holographic projectors installed in the display shelf.
