The present invention relates generally to the field of a projector system. More specifically, the present invention relates to an apparatus and system for providing a complete projector apparatus and system in communication with digital media.
Projectors have been used in educational environments for some time. These projectors and optical presentation devices are used in a wide variety of industries and in various settings and applications. For example, the projectors and optical presentation devices may be utilized in classrooms for teaching applications, conference rooms for business presentations and in a plurality of other learning and training facilities to be utilized to visualize a learning concept. Due to the relatively high cost of such devices, financial loss due to damage and theft to these devices tends to be a problem to companies, institutions and agencies that purchase and utilize these projectors and optical presentation devices. Therefore, these projectors and optical presentation devices are generally at least semi-permanent, in that they are mounted in a room and used with a projector screen also fixed in the room. However, because the projector is semi-permanent and left in the room even after use, these devices are subject to theft by individuals using the room afterword, and/or may be subject to damage by other occupants of the room. Often times, students, employees or other individuals may use a room that houses the projectors and may damage them either intentionally or inadvertently. The cost associated with fixing and/or replacing these units may be prohibitive and may cause some institutions to only use the projectors where absolutely necessary.
Traditional presentation or audio-visual (AV) carts accommodate LCD projectors and various digital presentation devices but lack a security system to protect the devices from theft. In order to reduce losses from theft, various security solutions are available from manufacturers of security products. Although some of the security solutions may have a primary objective of theft protection, they possess certain deficiencies which fail to protect against theft but still allowing for mobility of the presentation devices. Furthermore, many security solutions are unable to secure a variety of different types of presentation devices. In addition, many security solutions require permanent attachment of the presentation devices to a plate or other object in order to prevent damage to the projector unit or optical presentation devices.
Moreover, the security systems in place to help prevent damage and theft to projectors and optical presentation devices are inefficient for other reasons. For example, most conventional security devices are made to house the projector and are typically affixed to a structure within the room housing the projector unit. While they allow for protection of the projector unit, they also require removal and/or substantial dismantling in order to replace or repair the unit if something were to be functionally wrong with the projector. Another problem with these type of projector units and the security devices associated with these projectors is that they lack portability of the projector and/or optical presentation device from one location to another. Therefore, if the room configuration changes or class size increases, the entire projector assembly or the presentation device must be completely detached from its housing, and/or position in the room, and must be completely re-wired for another room. This would be overly cumbersome and extremely labor intensive. The movement of the projector from one room to another would also require moving the protective housing and wiring structure in one room and relocating the entire assembly to another room.
Moreover, even utilizing an AV cart may not be the best solution. AV carts, while allowing movement of the projector from one room to another, still require significant wiring to be performed once the cart has been moved from one location to another. Often times, the wiring systems in place in the room will require the AV cart to be placed in a very specific place within the room, such as a location having electrical power and wiring access to project an image onto a mounted or affixed board within the room. Another problem associated with these AV carts is that they have to be placed in a specific location within the room to project onto the board that is usually fixed in place. However, because the AV cart is usually rolled and moved often, and because of its location within the room, the potential for accidental bumping of the cart along with the projector associated therewith greatly increases. Further, the ability to restrict and diminish the possibility of damage to the projector unit is not decreased in any way. On the contrary, because of its location and accessibility to more individuals within the room, the likelihood of damage to the projectors is in fact increased.
Another problem with most of the prior art projector systems is the inability to adjust the presentation angles, depth and distance from the screen on which the optical information is displayed. For example, in many prior art projector applications, the distance from the projector screen is fixed and the projector must be aligned both vertically and horizontally on the screen to fit the space. In essence, the projector must be in the exact location of the screen to be viewable by an audience. And because most projectors are not able to be adjusted outside a specific vertical and horizontal maximum, the adjustment of the projectors sometimes just looks awkward, no matter how much adjustment is made to the projector and/or screen. Therefore, by having the projector affixed to a structure when installed in the room is the best way to avoid having to adjust the picture and the vertical and horizontal orientation of either or both the projector and/or the screen.

In one embodiment, the disclosed mount can effectively secure a projector or other digital presentation device to a support and which further provides the capability of allowing removal and relocation of the projector assembly from one location to another. In another embodiment, an improved projector assembly is provided that may be mounted to a screen assembly and may be connected to hardware that allows for a third party device to be plugged into the projector assembly without having to continually adjust the optical presentation device.

Various objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of preferred embodiments of the invention, along with the accompanying drawings in which like numerals represent like components.
Additional features and advantages of the present invention are described herein, and will be apparent from the detailed description of the presently preferred embodiments and from the drawings.
The following detailed description illustrates by way of example, not by way of limitation, the principles of the invention. This description will clearly enable one skilled in the art to make and use the invention, and describes several embodiments, adaptations, variations, alternatives and uses of the invention, including what is presently believed to be the best mode of carrying out the invention. It should be understood that the drawings are diagrammatic and schematic representations of exemplary embodiments of the invention, and are not limiting of the present invention nor are they necessarily drawn to scale.
Embodiments of the present invention comprise a projection system that permits the image projection device, to be semi-permanently or permanently positioned with respect to a projector screen. The weight of the projection device is generally reduced to permit easy installation and mounting with respect to the screen. A control unit un-connectable and re-connectable to the image projection device may include the electronics, power, light source, and other necessary circuitry, controls, and software to support the projection system. The control unit may be in a separate housing from the image projection device and connectable through one or more cables. The projection system may also include a connectivity plate that provides a light weight, multi-functional input interface to the projection system. For example, the connectivity plate may include user input options, such as buttons, toggles, switches, etc. as well as electronic interfaces, such as ports, plugs, jacks, etc. The connectivity plate may be separately housed from either or both of the image projection device and the control unit for easy access and interface for the projection system.
As shown and described, the projection system comprises three or more separately housed devices, including the projection device, the control unit, and the connectivity plate, coupled together by one or more connectors and/or cables. Each housing contains select components of the projection system. However, the embodiments as described herein are illustrative only and are not so limited. Alternatively, each device may be reconfigured, subdivided, combined, or otherwise configured, while remaining within the scope of the invention. Accordingly, components found within one housing may be moved to another housing, or components within one housing may be subdivided into two or more further housings. Considerations for the two or more housing configuration may be determined by the individual need of the environment and desired use, including the mounting configuration, installation constraints, permanence and/or portability of one or more portions of the system, security, accessibility, integration with other systems and diversity of third party devices, etc. For example, for a two housing system, the connectivity plate may be integrated into the control unit. Alternatively, for a four housing system, the light source from either the image projection device or the control unit may be separated into its own housing, including necessary circuitry and support features, such as fans.
The image projection device 102 is generally mounted on or near a projection screen 108. As shown, the image projection device 102 is mounted to a wall 108. In addition to a wall, the image projection device may also be mounted to a ceiling or back of a projection screen. The image projection device 102 may then be configured to provide, either directly or indirectly an image to the front of the screen. The image projection device 102 is generally light weight to provide easier installation. The image projection device 102 may contain limited components such as the image generator either alone or with a light source. The limited components reduce the weight of the image projection device to reduce the weight and increase the versatility of mounting options, while reducing installation costs. The image projection device may be positioned out of the way for easy continued use. The mounting may be permanent or semi-permanent such that the image projection device may be retained in generally the same location. Therefore, the image projection device may set up with respect to the projection screen so that the image focus, size, and position may be configured during installation and not reconfigured at each individual use; thus reducing set-up time between individual uses. Although the image projection device may generally be in the open, the mounting position and permanence may be selected based on the security requirements of the environment. Even in the event of a security breach and a image projection system is removed from the location, replacement costs may be reduced as a complete projection system does not have to be reinstalled because of the modular design of the system.
The control unit 104 is directly or indirectly coupled to the image projection device 102 through one or more cables and/or connections. The control unit 104 may include the supporting electronics and components for the image projection device 102. The control unit 104 as illustrated in
The connectivity plate 106 may also be independently positioned with respect to either or both of the image projection device 102 and the control unit 104 and directly or indirectly coupled to the control unit through one or more cables and/or connections. The connectivity plate 106 may provide input controls to a user as well as interface connections to other devices, systems, or networks. As shown in
Exemplary connectors may include one or more audio, video, composite, network connections such as Red/Green/Blue (RGB) Video Graphics Adapter (VGA), High Definition Multimedia Interface (HDMI), serial ports, such as RS232, network ports, such as Cat 6, or USB, as well as composite video/audio ports, such as RCA composite video, left and right audio. The connectivity plate may provide removable and/or interchangeable ports to allow connection interfaces to be upgraded as new technologies are released without needing to replace the entire plate.
The connectivity plate is contained within a housing. The housing may be configured depending on the needs of the environment as well as the desired connection and control interface features. The housing and associated connectors and controls may be coupled to the control unit through one or more connectors. In an exemplary embodiment the connector plate may simply be a pass through from a connected device to the control unit allowing easy access to the projection system in a convenient, lightweight, easily manipulated and movable device. Alternatively, the connectivity plate may include hardware and software to convert any incoming signal, into a single signal protocol before forwarding onto the control unit. For example, regardless of the connected source, all A/V signally may be converted to HDMI before being transmitted to the control unit. The connectivity plate may include one or more integral or connectable cable between the connectivity plate and the control panel depending on what, if any, pre-processing is performed within the connectivity plate.
The connectivity plate may include user controls 202 such as a source selection 202a, volume 202b, and power 202c. The source selection 202a may be used to select which coupled device to project through one or more of the connectors 204. Other user controls may be present as desired by a user, such as focus, zoom, brightness, color, contrast, etc. The user controls may be in the form of buttons, toggles, keys, switches, pads, touch screen, or other input means. The user controls may be duplicated between one or more portions of the projection system.
The connectivity plate may also include a power cord or other power source. Alternatively, the connectivity plate may obtain power from the control panel through one or more connections between the connectivity plate and the control panel. If power is unnecessary, such as if the connectivity plate is simply a pass through to the control panel, the connectivity plate may not include a power source.
In an exemplary embodiment, the control unit 104 is a modular system consisting of four major components that can be replaced independently in the field. The described components are exemplary and may be subdivided, combined, removed, or incorporated into other portions of the projection system 100. First, the control unit 104 may include electronics, as hardware or software, to control the projection system 100. For example, a main circuit board, including a processor, memory, and/or other electronic hardware supporting software may be included to handle the projection system's operations. Second, the control unit 104 may include a power system. For example, the control unit 104 may include the power supply of the projection system, and may include for example, a standard alternating current (AC) cord 302 and plug. The control unit 104 may include internal hardware to provide high voltage to external components through one or more outlets, connectors, or cables on the outside of the unit. For example, one or more outlets 304 may be present to provide power to other devices, such as connected computers, and/or other parts of the projection system. Third, the control unit 104 may include a connector extender, for third party device connectivity. In an exemplary embodiment, the control unit 104 include one or more connector ports. For example, USB in 306a and USB out 306b ports may be provided for third party connectivity such as to a computer. The USB ports 306a and 306b may be used for connectivity pass-through and active extension for third-party products, for example interactive white boards. Other additional or alternate connectors may also be included such as RJ 45 connector port 306c. The serial port may be used for networking the projector and/or network control of the projector. Finally, the control unit 104 may include a light source. The light source may be a lamp module which can be a traditional Ultra High Performance Lamp or Light Emitting Diode, or other known projection light source.
The control unit 104 may be coupled to the connectivity plate 106 by one or more cables. As shown, a single HDMI connection cable 312 is present when the connectivity plate converts the received single to a common protocol before forwarding onto the control unit. Alternatively, one or more connectors may be used to support different protocols coupled to the connectivity plate depending on the device connected. The control unit may then include hardware and/or software to convert the incoming signal into a desired usable format. Other connections may also be present, and does not necessarily include physical wiring. For example, wireless or other non-physical connection may be used between the control unit 104 and the connectivity plate 106.
One or more connectors may also be coupled between the control unit 104 and the image projection device 102. One connector may be used as a control cable 310, in which electrical signals, data information, or power are sent between the image projection device 102 and the control unit 104. In an exemplary embodiment, the image projection device 102 is connected to the control unit 104 with a single control cable. This cable may transmit power, control and image information to the image projection device, including the image generator.
As shown in the combination of
In an alternative embodiment to using the light guide, the light source or light generation equipment may be housed in the control unit 104 and use laser light technology to port the light to the image projection device.
As seen in
The image projection device 102 may also include an arm 404 that may be positionable relative to the mounting interface 406 and the projection screen. In an exemplary embodiment, the arm is flexible to allow the installer and/or user to easily align the projected image onto a screen. The arm may be flexible along its length, or may be made of one or more jointed segments that provides variable positions of the head 402 relative to the mounting interface 406. The arm may also enclose one or more cables, for example the liquid light guide or the control cable. The enclosed cables may traverse or pass through the mounting plate or exit at an end or along the arm near the mounting interface 406. For example, an integral cable may be enclosed within the arm 404 between the head 402 and the mounting interface 406. The mounting interface may then include one or more connectors for coupling an associated cable to another portion of the projection system 100, such as to the control unit. Alternatively, a single integrated cable may run from the head 402 through the aim 404 and may be sufficiently long to connect directly to a port on the control unit, without requiring a separate extender.
The mounting interface 406 may be any connection system to removably, permanently, or semi-permanently position the head 402 with respect to a projection screen, and/or the mounting interface with respect to a mounting surface. For example, the mounting interface 406 may include a clamp mount, wall mount, or self adhesive mount to a mounting surface. The mounting interface 406 may be configured to correspond to a desired mounting surface, such as, for example, a wall, ceiling, or surface or side/edge of the projection screen. The arm 404 may be configured to properly position the head 402 relative to the projection screen depending on the mounting option chosen. For example, a mounting system for securing the head 402 to the back surface of the projection screen may include an extension to the arm 404, such that the head is positioned on a front side of the screen opposite the mounting interface. The extension arm may be selectively incorporated depending on the mounting options available at a given location. The mounting interface 406 may also include hardware and/or software for supporting the projection of an image.
The image projection device 104 may also include interface options, such as input control buttons 408a and 408b. The interface options may include control inputs that permit image manipulation during installation of the image projection device 104. In an exemplary embodiment, the image projection device 104 may be mounted through the mounting interface. During the mounting process, the image projection device, may be properly positioned by orienting the arm and the mounting interface as desired with respect to a mounting surface and a projection screen. The interface on the image projection device may then be used during installation to properly focus, zoom, or otherwise create a desired projected image onto the projection screen. These controls on the image projection device directly permits an installer to simultaneously configure the position and the image settings from one location. The control interface may be positioned on either the mounting interface, the arm, or the head. Control interface features may include, for example, zoom 408a or focus 408b, but may also include any combination of setting features for the projection system 100. These control features may be incorporated into other portions of the projection system to improve accessibility depending on the position of the user.
Embodiments, as described herein, provide a modular solution to projection systems. The modular components provide increased interchangeability, installation options, reduced installation costs, reduced replacement costs, reduced upgrade costs, and generally greater versatility. Embodiments as described herein are illustrative only. Each of the modular components, including the connectivity plate, control unit, and image projection device may be contained within separate housings. The housings may be configured according to the needs of the environment. Each housing may include one or more connector for coupling separate housings together. The connectors may removeably coupled to each house and/or permanently coupled or otherwise integrated into one or more of the individual housings. The features of one or more of the modular components may be duplicated or transferred from one component to another. Alternatively, the modular components may be subdivided, combined, or otherwise reconfigured to meet the requirements of the use and environment. Embodiments as described herein generally describe a projection system for use with a screen. The screen may include any surface for projecting an image, such as a wall, white board, chalk board, other board, retractable screen, etc.
