An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

A method and apparatus for mounting a projector holder to or placing a projector holder on an object for displaying an image onto a surface is disclosed. The projector holder includes a body within which a projector is at least partially disposed. The body includes one or more pliable appendages that are adapted to be manipulated and deformed from a first configuration to a second configuration. In some embodiments, the body is formed in the shape of an animal.

An adjustable hanging device for securing an electronic device and being capable of angular adjustment is provided. One control screw is disposed for the operation along one dimension. When the adjustable hanging device is used for multi-dimensional angular adjustments, the control screws are disposed to extend to one operational side. Due to the mechanical integration and the compact design of the adjustable hanging device, the advantages of volume reduction and simpler manipulation at one operational side would be expectable.

A projector includes a base, an optical engine assembly, a lens assembly, a connector, and a buffer. The base includes a primary plate body and a first connection part connected to the primary plate body. The optical engine assembly is configured to provide an image beam. The lens assembly is arranged above the base and located on a transmission path of the image beam. The connector includes a first fixing part and a second connection part connected to the first fixing part. The first fixing part is fixed to the lens assembly, one of the first connection part and the second connection part is a slot, and the other is movably inserted into the slot. The buffer is arranged in the slot, and the first connection part is connected to the second connection part through the buffer. The projector may effectively prevent lens vibration.

A vehicular heads-up-display system includes an apparatus having a base configured to receive and maintain a pico-projector case in combination with a handheld electronic device, and to output optical transmissions from the pico-projector case to an at least partially reflective surface to form a heads-up display. The partially reflective surface may be a combiner and/or mirror coupled to a base comprising the holder. The handheld electronic device may be a smartphone. For example, the system can be used to cause a pico-projector to project information from a smartphone to a partially reflective mirror for viewing by a vehicle operator.

A convertible display includes a number of video display panels which are movable between a first position in which the panels extend in the same plane to define a unified display and a configuration in which one or more of the panels are moved into other planes which allow them to form steps. Multiple of the rotated panels may form a sequence of steps, e.g. a staircase. The convertible display may be moved via a robotic mount, whereby the position or orientation of the convertible display may be changed.

A portable system is provided for engaging users during play by presenting one or more images provided by a mobile computing device. The system includes a projector configured to visually output the one or more images delivered by the computing device. The system also includes a mount for supporting the projector, and at least one lens that is coupled to the projector. The system further includes a housing having at least a first and second illuminable surface that can receive images projected by the projector. The surfaces can be moved between a collapsed condition and an operative condition.
