Embodiments of an apparatus and system are described for a hybrid computing device. Some embodiments may comprise a computing device having an enclosure arranged to support a display on a front of the enclosure, a projector adjustment ring integrated into a portion of the perimeter of the enclosure, and a projector module adjustably coupled to the projector adjustment ring. In various embodiments, the projector module may be arranged for dual-axis rotation within the projector adjustment ring. Other embodiments are described and claimed.

An image projection device for displaying an image onto a remote surface. The image projection device employs a scanner to project image beams of visible light and tracer beams of light onto a remote surface to form a display of the image. The device also employs a light detector to sense at least the reflections of light from the tracer beam pulses incident on the remote surface. The device employs the sensed tracer beam light pulses to predict the trajectory of subsequent image beam light pulses and tracer beam light pulses that form a display of the image on the remote surface in a pseudo random pattern. The trajectory of the projected image beam light pulses can be predicted so that the image is displayed from a point of view that can be selected by, or automatically adjusted for, a viewer of the displayed image.

It is an object to provide a small and inexpensive laser light source device capable of efficiently focusing rays of laser light from a plurality of laser light sources so as to increase output, and to provide an inexpensive and small video display device. The plurality of laser light source units are arranged in such manner that the plurality of laser light source units adjacent to each other adjoin each other in series. The laser light source device further includes a second reflection mirror reflecting, in a third direction, a ray of laser light reflected in a second direction. The second reflection mirror is held by a mirror holder belonging to one laser light source unit among the plurality of laser light source units.

The present invention describes a hologram projector that is used to project three dimensional high definition images on the screen using various electronic devices. The hologram projector can provide an upright display that is comfortable to view while allowing the electronic device to lay flat, by incorporating a completely or partially reflective material along with the hologram projector. The projector works on the Liquid crystal on silicon (LCOS) technology for projecting the images. The hologram projector can be connected to electronic devices like smartphones, laptop, personal computers tablets, media players etc. either through wired or wireless connections. The media file has to be loaded in the electronic device and the electronic device has to be connected to the hologram projector through wireless or wired connection and the hologram can be displayed on the high definition screen up to 150 inch.

The present disclosure relates to the technical field of digital projection display, and discloses a projection method and a projection apparatus. The method includes: acquiring a target object image; identifying attribute information of a target object based on the target object image; acquiring preset projection content based on the attribute information of the target object; acquiring a projection path; and projecting a projection screen based on the preset projection content and controlling the projection screen to move along the projection path. In this way, the projection is more flexible and more pertinent.

A projection apparatus and a control method thereof are provided. The projection apparatus includes a light source, an optical engine, a first sensor, and a processor. The light source provides a light beam to the optical engine. The optical engine converts the light beam into an image beam and projects the same out of the projection apparatus. The first sensor senses an ambient temperature. The processor is coupled to the optical engine, the light source, and the first sensor, records a projection time of the optical engine, selects a selected temperature range in which the ambient temperature is included from multiple temperature ranges according to the ambient temperature, and selects a selected driving program from multiple driving programs corresponding to the temperature ranges according to the selected temperature range to control the light source. A brightness of light beam is negatively related to the projection time.

The invention is a small, low-power consuming, projector system. Once programmed and provided with image data, it can be a standalone system for presenting varying length, silent, videos. Its programmability and FPGA-based micro-circuitry allows it to be repurposed with minimal effort to support other embedded-light-system applications.

A smart laser phone includes a main body with a mobile communication module, a band connected to the main body, an optical member, on a side surface of the main body to which the band is not connected, for projecting a laser image, a speaker on the same side surface as the optical member but separated by a set distance therefrom, a sensor unit on the surface between the optical member and the speaker, and a microphone on the outer side of the optical member. When the smart laser phone is worn on the wrist, the microphone and the optical member, the sensor unit and the speaker are sequentially equipped on the side surface of the smart laser phone main body oriented toward the palm, and thus, as the phone is used with an enlarged image, using the phone is convenient, and communication can be carried out with clear sound.

Described are a method and device for multi-source control of an intelligent miniature projector. With the method, connection of intelligent miniature projector equipment with multiple UEs is established; after a projection request sent by a first UE is received, when it is detected that played content of a second UE is being projected, a switching confirmation prompt is sent to the second UE; and after the second UE's consent for switching is received, the current projection process is stopped, a response to the projection request of the first UE is made, and played content of the first UE is projected.
