Description

Technical Field

[0001]

[0001] The present disclosure relates generally to image projectors, and more particularly to projectors and projection systems for aircraft and methods for projecting images onto the interior of an aircraft.

Background Art

[0002]

[0002] Screen displays are widely used within commercial aircraft. Various in-flight entertainment (IFE) systems are also widely adopted by airlines for longer flights. However, existing screen displays and IFE systems have various drawbacks. Conventional displays and IFE systems are expensive in terms of material costs, labor, installation time, and power consumption. Conventional screen-based systems are also heavy. For example, the weight of a conventional IFE system can range from 800 to 1200 pounds per aircraft, resulting in undesirable fuel consumption and CO2 emissions. Conventional screen-based systems may also become obsolete early in the operating life of an aircraft. Furthermore, conventional IFE systems are limited to displays in fixed positions. Therefore, the display position cannot be adjusted, the applications are limited, and an optimal viewing experience is often not obtained. Additionally, conventional IFE systems have limited or no functionality to provide an interactive experience. Accordingly, those skilled in the art continue to make research and development efforts in the field of interior image projection for aircraft cabins.

[0058]

[0075] Multiple embodiments of the projector 100, projection system 200, and method 1000 described and shown herein advantageously utilize projection technology significantly different from screen display systems conventionally used in aircraft. Multiple embodiments of the projector 100, projection system 200, and method 1000 can be far more efficient than conventional IFE systems for both weight reduction and power consumption savings. Multiple embodiments of the projector 100, projection system 200, and method 1000 provide automated (e.g., robotic) control that enables flexible display capabilities at most positions and / or surfaces within the aircraft cabin. Multiple embodiments of the projector 100, projection system 200, and method 1000 improve cabin management efficiency. Multiple embodiments of the projector 100, projection system 200, and method 1000 facilitate interactive displays and improve the passenger in-flight experience by using sensors to recognize interactive (e.g., gesture) control.

[0059]

[0076] Multiple embodiments of the projector 100, projection system 200, and method 1000 described and shown herein offer a lightweight and space-saving design. In one or more embodiments, most of the operating components of the projector 100 are integrated into a small, rotatable circular disc that forms part of the drive assembly 140. The housing 110 can be mounted on or integrated into the interior panel of the cabin or other support structure. In one or more embodiments, the housing 110 and / or the drive assembly 140 include flexible connectors (e.g., silicone or rubber dampers) that function for both fixation and passive vibration absorption. By using the housing 110, display controller 120, and controller 230, the projector 100 can become a plug-and-play component of an aircraft 1200. Horizontal and vertical rotational degrees of freedom, coupled to the support structure using gears, drive the housing 110 of the projector 100. The two rotational degrees of freedom are used for both display stabilization and switching of the projected display area. The projector rack 112 of the projector 100 is designed to structurally support the housing 110 by arranging two or more instances of the display engine 130 at specific angles, integrating the main printed circuit board and other electronic devices in multiple layers relative to the housing 110. In one or more embodiments, collaboration takes place between the interactive sensor 220 and the projector 100 to control the display content with gestures or to automatically respond to changes in the surroundings.

[0085] In this specification, a system, apparatus, device, structure, article, element, component, or hardware described as “configured to” perform a particular function is, in fact, capable of performing that particular function without any modification, rather than merely having the potential to perform that particular function after further modification. In other words, a system, apparatus, device, structure, article, element, component, or hardware described as “configured to” perform a particular function is specifically selected, created, implemented, used, programmed, and / or designed for the purpose of performing that particular function. As used herein, “configured to” means that there exists a characteristic of the system, apparatus, structure, article, element, component, or hardware that enables the system, apparatus, structure, article, element, component, or hardware to perform a particular function without further modification. For the purposes of this disclosure, a system, apparatus, device, structure, article, element, component, or hardware described as “configured to” perform a particular function may additionally or alternatively be described as “adapted to” and / or “operative to” perform that function.

[0069]

[0086] Unless otherwise indicated, terms such as “first,” “second,” and “third” are used solely as symbols in this specification and are not intended to impose any sequential, positional, or hierarchical requirements on the items they refer to.

In various examples, these elements may be directly related or indirectly related. For example, element A may be directly related to element B. In another example, element A may be related to element B, for example, via another element C. It should be understood that not all relationships between the various elements disclosed are necessarily represented. Therefore, other couplings may exist that are not shown in the drawings.

[0072]

[0089] In this specification, the term “approximately” refers to or represents a state that is close to, but not exactly, a specified state in which the desired function is still performed or the desired result is achieved. For example, “approximately” refers to a state that is within a given acceptable tolerance or precision range, such as a state that is within 10% of the specified state. However, the word “approximately” does not exclude a state that is exactly the same as the specified state. As used herein, the word “substantially” refers to a state that is essentially the same as the specified state in which the desired function is performed or the desired result is achieved.
