Description

[Background technology]

[0001] The field of the disclosure relates generally to translucent projection systems, and more particularly to projecting images and videos onto translucent displays integrated into changing tables.

[0002] Many purchasers of aircraft and other fleet vehicles require that their vehicles be personalized for their brand or image. In many cases, this includes logos or images on various surfaces of the vehicle. However, many of these customizations are expensive and would need to be removed if the vehicle were to be resold. Such customizations also require special setups on the assembly line, slowing down the manufacturing process. Furthermore, such customizations would need to be accomplished in areas where space for additional equipment is limited. One particular area of customization is the vehicle's restroom, where purchasers expect prominent features to improve restroom visibility and passenger comfort. Therefore, it would be advantageous to have a system that allows for customization of vehicle surfaces without requiring modifications to vehicle manufacturing. Summary of the Invention

[0007] The implementations described herein relate to systems and methods for analyzing images, particularly translucent projection systems, and more particularly to projecting images and videos onto a translucent display integrated into a changing table constructed of one or more translucent materials. For the purposes of this discussion, the translucent material or display allows light to pass through but scatters the light so that objects on the other side are not clearly visible. In some examples, the translucent display is made of a material including acrylic polymer and alumina trihydrate (ATH), similar to the Corian® material (a solid material) made by EI duPont de Nemours and Company of Wilmington, Delaware.

[0008] In particular, a translucent projection system includes a projector, such as a short throw projector, controlled by a projector controller computing device that controls the projector while transmitting an image to be displayed on a translucent display. The projector projects an image onto the projection surface of the translucent display, and the image is displayed on the display surface of the translucent display through the translucent display. Projecting onto the projection surface of the translucent display ensures that there are no obstacles between the projector and the projected translucent display. This prevents individuals from getting between the projector and the projected display, thereby preventing shadows and other obstacles from obscuring the image. The projector is also hidden away from the viewer, improving the viewing experience. Furthermore, the projector can be configured to display a desired image, allowing for customization without the need for additional equipment. Furthermore, the image can be changed when desired. The projector can be configured to display an image, a series of images, video, and / or animation.

[0009] In the case of a changing table, the projector controller computer device communicates with one or more sensors that alert the projector controller computer device when the changing table is in the up or stowed position, or when the changing table is in the down or extended position. The projector controller computer device commands the projector to display an image when the changing table is in the up or stowed position, and commands the projector to pause projection when the changing table is in the down or extended position. While a changing table is used herein as an exemplary implementation, one reading this specification will recognize that other implementations and applications are within the scope of this disclosure, including, but not limited to, other storable support surfaces such as trays, tables, and workspaces, among others.

[0020] 1 illustrates a projector system 100 for projecting an image onto a translucent display 105 according to the present disclosure. In one example, the translucent display 105 includes a translucent material that allows light to pass through but is semi-transparent. For the purposes of this discussion, a translucent material or a translucent display allows light to pass through but scatters the light so that objects on the other side are not clearly visible. In some examples, the translucent display 105 is made of a material including an acrylic polymer and alumina trihydrate (ATH), similar to the Corian® material (a solid material) made by EI duPont de Nemours and Company of Wilmington, Delaware.

[0021] In this example, the translucent display 105 includes a display surface 110 and a projection surface 115, where the display surface 110 faces a viewer (or observer) 120 and the projection surface 115 faces one or more projectors 125. Although the projector 125 shown in FIG. 1 is below the translucent display 105, one or more projectors 125 can be located above the translucent display 105, on either side of the translucent display 105, or even directly behind the translucent display 105. The one or more projectors 125 are configured to project an image 130 onto the projection surface 115 of the translucent display 105. The image 130 is then viewed by the viewer 120 through the translucent display 105. In one example, the projector 125 projects the image 130 in an inverted manner so that the image 130 can be displayed in the correct orientation by the viewer 120. In one example, the projector 125 is at least one of a short throw projector, an ultra-short throw projector, a GOBO (goes before objects) projector, or other projector that functions as described herein. The term GOBO (Go Before Optics) specifically refers to an element located at the “gate” or “point of focus” between a light source and a lens (or other optical system). In this example, the projector 125 is only a short distance from the translucent display 105 and is configured to project onto the translucent display from this short distance. Additionally, the projector 125 is configured to project onto a curved or non-flat surface so that the image 130 does not appear distorted to the viewer 120. In this example, the projector 125 is programmed to adjust the projected image 130 to the contours and outline of the translucent display 105 onto which it is projected to avoid skew. This adjustment can be made when the projector 125 is initially set up during installation. In addition, the projector 125 is also configured to utilize keystone image correction techniques where the projector 125 is at a certain angle relative to the projection surface 115 of the transflective display 105 .

[0022] Projector 125 is controlled by projector controller 135. Projector controller 135 instructs projector 125 regarding which image 130 to project and when to project the image. Projector controller 135 may provide images to projector 125. Projector controller 135 may also provide images to projector 125 that are adjusted to the contours of translucent display 105. If projector controller 135 determines that it is appropriate to enter sleep mode, projector controller 135 instructs projector 125 to stop projecting image 130 to conserve energy, reduce heat, and / or reduce wear on projector 125. Projector controller 135 may activate sleep mode for a predetermined period of time after a sensor signal is received, after a series of images has been displayed for a predetermined period of time, after a particular sensor signal is received, or based on instructions from one or more other computing devices. In some examples, projector controller 135 is part of projector 125. In other examples, projector controller 135 is separate from and communicates with projector 125. In some further examples, projector controller 135 controls multiple projectors 125.

[0023] 2 shows a block diagram of another projector system 200 for projecting an image onto a translucent display 105 according to another example of the present disclosure. In projector system 200, translucent display 105 includes a display surface 110 and a projection surface 115. Display surface 110 faces a viewer (or observer) 120. Projector system 200 also includes multiple projectors 125. Each of the multiple projectors 125 is configured to project an image 205 or 210 onto projection surface 115 of translucent display 105. Projector controller 135 controls each of the projectors 125 and determines which portion of image 210 each projector 125 displays based on the size and shape of translucent display 105.

[0024] Further, the projectors 125 are configured to project the images 210 such that they include an overlap region 215. The overlap region 215 combines the images 210 of the two projectors 125 to create a seamless image, such that there are no visible differences between the images 205 to the viewer 120. The projector controller 135 is programmed to control the multiple projectors 125. The projector controller 135 instructs each projector 125 which images 205 and 210 to project and what to project in the overlap region 215. The projector controller 135 can utilize color matching and edge blending techniques to illuminate the overlap region 215, such that there are no visible differences between the images 205, 210, and the overlap region 215 to the viewer 120.

[0025] FIG. 3 is a simplified block diagram of an exemplary projector system 300 for implementing projector systems 100 and 200 (shown in FIGS. 1 and 2). In this example, projector system 300 is used to control projector 125. Projector system 300 includes a projector controller computing device 310 (also known as a projector controller server), which is a computer system that controls the projector and is configured to project an image onto a surface. In some examples, projector controller computing device 310 is programmed to control one or more projectors 125 based on data received from one or more sensors 305. In this example, projector controller computing device 310 is similar to projector controller 135 (shown in FIG. 1).

[0026] Projector 125 is configured to project image 130 onto projection surface 115 of translucent display 105 such that image 130 is displayed on display surface 110 of translucent display 105 (all shown in FIG. 1).

[0027] In projector system 300, sensors 305 receive signals about user actions. Sensors 305 may include, but are not limited to, faucet sensors, door lock sensors, flush button sensors, automatic paper towel dispenser sensors, motion sensors, infrared sensors, light sensors, and / or any other sensors that enable projector system 300 to operate as described herein. Sensors 305 connect to projector controller computing device 310 via various wired or wireless interfaces, including, but not limited to, a local area network (LAN) or a wide area network (WAN), a dial-in connection, a cable modem, an Internet connection, or a special high-speed wireless link (Integrated Services Digital Networks (ISDN)). Sensors 305 receive data about user or system activity and report these conditions to projector controller computing device 310. In another example, sensors 305 communicate with one or more client systems 325. In some examples, the sensor 305 communicates directly with one or more projectors 125, and the projectors 125 are activated directly based on signals provided by the sensor 305. For example, if a motion sensor detects motion, the projector 125 can be activated.

[0028] In this example, client system 325 is a computer including a web browser or software application that allows client system 325 to communicate with projector controller computer device 310 using the Internet, a local area network (LAN), or a wide area network (WAN). In some examples, client system 325 is communicatively connected via multiple interfaces, including, but not limited to, at least one network, such as the Internet, a LAN, a WAN, or ISDN, a dial-up connection, a digital subscriber line (DSL), a cellular connection, a satellite connection, or a cable modem. Client system 325 may be any device capable of accessing a network, such as the Internet, including, but not limited to, a desktop computer, a laptop computer, a personal digital assistant (PDA), a cellular phone, a smartphone, a tablet, a phablet, or other web-based, connectable device. In at least one example, one or more client systems 325 are associated with the operation of the aircraft, such as when to project images back onto seats. In another example, client systems 325 provide real-time information, such as economic news, to projector controller computing device 310, which can then instruct one or more projectors 125 to display the economic news on translucent display 105.

[0029] Database server 315 is communicatively coupled to database 320, which stores data. In one example, database 320 is a database containing projector settings, projection sequences, and additional information about the projections. In some examples, database 320 is stored remotely from projector controller computing device 310. In some examples, database 320 is distributed. In some examples, a person can access database 320 via client system 325 by logging into projector controller computing device 310.

[0030] 4A and 4B show cross-sectional views of a sink-based projector system 400 according to at least one embodiment. The sink-based projector system 400 includes a counter 405, a sink area 410, and a splash-proof area 415. In this example, the sink-based projector system 400 also includes one or more projectors 125 configured to project an image 425 onto one of the counter 405, the sink area 410, and the splash-proof area 415.

[0031] In this example, projector 125 is configured to project an image when triggered by trigger device 420, such as a faucet sensor. Trigger device 420 can include one or more sensors 305 (shown in FIG. 3 ), which report the current state (i.e., on or off) of trigger device 420. In sink-based projector system 400, trigger device 420 is a faucet sensor that detects a person placing their hands near sink area 410. Trigger device 420 then triggers water to be dispensed into the sink. Trigger device 420 sends a signal to projector controller 135 (shown in FIG. 1 ), which controls projector 125. Projector controller 135 commands projector 125 to project one or more images 425. Projector controller 135 can also poll each trigger device 420 to determine its current state, such as whether a faucet is actively dispensing water.

[0032] 4C shows a top-down view 450 of the operation of sink-based projector system 400 (shown in FIGS. 4A and 4B), in which, by way of example, an image of swirling water 425 is projected onto sink area 410.

[0033] 5 shows a diagram 500 of a restroom using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). Diagram 500 shows multiple display surfaces 110 of translucent display 105 (shown in FIG. 1) with images projected onto them, including counter surface 505, sink area surface 510, and splash guard area surface 515. All three surfaces 505, 510, and 515 are displaying image 130 (shown in FIG. 1) instructing viewer 120 (shown in FIG. 1) to return to their seats, such as in an aircraft restroom.

[0034] In other situations, other images 130 may be displayed on the surfaces 505, 510, and 515, such as, but not limited to, branding and logos, destination themes, journey progress information, news, emergency instructions, economic data (e.g., stock quotes), video clips, and / or any other desired image or video. These images 130 may be displayed based on activation of a trigger device 420 (shown in FIG. 4), a control signal from a projector controller 135 (shown in FIG. 1), and a signal from a client system 325 (shown in FIG. 3). In a first example, the projector controller 135 receives a signal from the trigger device 420 that the trigger device 420 has been activated. This signal causes the projector controller 135 to instruct one or more projectors 125 to project the image 130 onto one or more surfaces 505, 510, and 515. In a second example, projector controller 135 determines that a predetermined time has passed since the most recent signal from sensor 305 or trigger device 420 and commands projector 125 to stop displaying image 130. In a third example, projector controller 135 may receive a signal from client system 325 that instructs projector controller 135 to command projector 125 to display image 130 of a person back at their seat on each of surfaces 505, 510, and 515.

[0035] FIG. 6 shows a diagram 600 of a restroom using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). In diagram 600, projector 125 (shown in FIG. 1) is hidden in the wall behind a changing table 605. The changing table 605 is a translucent display 105 (shown in FIG. 1) and is made of a translucent material. While the changing table 605 is in the up or stowed position, projector 125 projects an image 610 onto the surface of the changing table 605. In this example, when the changing table 605 is unfolded or in the down or extended position, projector 125 stops projecting image 610. In another example, projector 125 is inside the changing table 605, and the underside of the changing table 605 is a translucent display 105. In some examples, when an audience member 120 (shown in FIG. 1 ) is detected, the projector 125 begins projecting the image 610. For example, when a restroom lock is pressed into the locked position, the lock includes a trigger device 420 (shown in FIG. 4A ). The trigger device 420 sends a signal to the projector controller 135 (shown in FIG. 1 ) instructing the projector 125 to display the image 610 on the changing table 605. The projector controller 135 can also receive a signal from the trigger device 420 associated with the changing table 605 to determine whether the changing table 605 is in the up or stowed position or the down or extended position.

[0036] Although a diaper changing table is utilized herein as an exemplary implementation, reading this specification will recognize that other implementations and applications are within the scope of this disclosure, including, but not limited to, other foldable support surfaces, such as trays, tables, and workspaces, among others.

[0037] 7A-7C show a top-down view 700 of a changing table 605 including a transparent display 105 (shown in FIG. 1) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). In FIG. 7A, the view 700 includes a cutaway view of the changing table 605 in a stowed or up position. In FIG. 7B, a view 725 illustrates the changing table 605 in an extended or down position. In FIG. 7C, a view 730 illustrates the changing table 605 in use. The changing table 605 is configured to transition between a stowed position and an extended position. The changing table 605 includes a hinge or other movement mechanism that enables the transition between the stowed or up position and the extended or down position.

[0038] As shown in diagram 700, translucent projection area 720 includes projection surface 115 and display surface 110. The translucent material of translucent projection area 720 is configured to allow image 130 to be projected onto projection surface 115 and displayed on display surface 110.

[0039] A projector 125 is disposed within the wall 705. The projector 125 may be a backlit short-throw projector 125. The projector 125 projects an image 130 onto a projection surface 115 of the changing table 605 through a lens 710 in the wall 705. The display surface 110 of the changing table 605 is the bottom surface of the changing table 605 when the table is unfolded or lowered. The projection surface 115 of the changing table 605 is the top surface of the changing table 605 when the table is unfolded or lowered.

[0040] The lens 710 may be a fisheye or wide-angle lens, allowing the image 130 to be expanded to display a larger area. When the changing table 605 is unfolded, the lens 710 will be visible in the wall 705. The lens 710 may be protected by a shutter 712, such as a camera-type shutter. The shutter may be a rotating shutter, a guillotine shutter, an aperture shutter, an iris shutter, or some other type of mechanism. When the changing table 605 is unfolded or in the down position, the shutter 712 closes over the lens 710. The lens 710 may also be protected by an optional transparent cover 714 attached to it or combined with the shutter 712.

[0041] Changing table 605, or a portion thereof, is made of a material including an acrylic polymer and alumina trihydrate (ATH), similar to the Corian® material (a solid material) made by EI duPont de Nemours and Company of Wilmington, Delaware. Image 130 travels through the portion of changing table 605 onto which it is projected and is displayed on display surface 110 of changing table 605. Image 130 is then viewable on display surface 110 of changing table 605. Image 130 is inverted and projected onto projection surface 115, where it is displayed in the correct orientation on display surface 110.

[0042] As shown in diagram 700, projector 125 is positioned orthogonally relative to translucent changing table 605, allowing image 130 to be transmitted clearly and without distortion. Projector 125 can also be positioned at an angle relative to translucent changing table 605 and keystone image correction can be used to account for that angle. This can include moving projector 125 and lens 710 to other positions along the wall based on the available space requirements of the restroom and / or wall 705 containing projector 125 and lens 710. Additionally, multiple static image projectors 125 can be used, where projector controller 135 cycles images between static image projectors 125 to display animation or pseudo-animation.

[0043] Placing the projector 125 behind the wall 705 allows the projector an unobstructed path to project the image 130 onto the translucent changing table 605 .

[0044] The projector controller 135 instructs the projector 125 on which images 130 to display and when to display them. The projector controller 135 communicates with one or more sensors 305 (shown in FIG. 3 ), which inform the projector controller 135 of the current position of the changing table 605. The sensors 305 may include, but are not limited to, proximity switches, magnetic switches, level switches, tilt / displacement switches, radial switches, mercury switches, latch sensors, and / or any other position sensors 305 that inform the projector controller 135 of the current position of the changing table 605. The projector controller 135 can disable projection upon detecting that the changing table 605 is no longer in the fully stowed position, thereby preventing the projector 125 from projecting light into the user's face.

[0045] When the changing table 605 is stowed, closed, or raised, the sensor 305 signals the projector controller 135 about the current position of the changing table 605. The projector controller 135 can instruct the projector 125 to display one or more images, videos, and / or animations on the translucent display 105 of the changing table 605. When the changing table 605 is opened or unfolded, the sensor 305 notifies the projector controller 135 of the current position, and the projector controller 135 instructs the projector 125 to stop projecting the image 130. When the sensor 305 notifies the projector controller 135 that the changing table 605 is closed or stowed again, the projector controller 135 instructs the projector 125 to resume projecting the image 130. In some examples, the projector 125 communicates directly with the sensor 305 to know when to disable projection.

[0046] In a first example, the changing table 605 includes a boundary region 715 and a translucent projection region 720. As shown in diagram 700, the boundary region 715 is thicker than the translucent projection region 720, where the translucent projection region 720 is recessed relative to the surrounding boundary region 715. The boundary region 715 disposed around the translucent projection region 720 provides an area for a baby 735 to rest safely and limits the possibility that the baby 735 and any other objects, such as a change of supplies, within the translucent projection region 720 will roll off the changing table 605. The translucent projection region 720 is the area where the baby 735 will rest when the changing table 605 is lowered or unfolded.

[0047] In some examples, the translucent projection area 720 is made of a different material than the border area 715. In other examples, the changing table 605 can include a single thickness of translucent material, where the area where the baby 735 is placed is not recessed, or is shaped so that the area where the baby 735 is placed is recessed. The changing table 605 can include one or more portions made of a translucent material that allows the projection image to pass through, and one or more portions made of a different opaque material.

[0048] The changing table 605 can be made from a single translucent material. The changing table 605 can also be made from multiple different materials that are adhesively joined together with color-matching adhesives, etc. The translucent projection area 720 of the changing table 605 can be made by thinning localized areas via one of machining, chemical etching, thermoforming, molding, composite materials, and / or can be made as a multi-part assembly.

[0049] Projector 125 may be activated when projector controller 135 (shown in FIG. 1) receives a signal from one or more trigger devices 420 (shown in FIG. 4A). For example, when a restroom is not in use, projector controller 135 places projector 125 in a low-power mode. Projector controller 135 may do this a predetermined time after any trigger device 420 in the restroom is activated, or a predetermined period of time after one or more specific trigger devices 420 are activated. For example, projector controller 135 may command projector 125 to enter low-power mode two minutes (120 seconds) after the door is unlocked.

[0050] The projector 125 can enter several different power modes. The first power mode is a normal power mode, in which the projector 125 projects the image 130 onto the translucent display 105 at full brightness (which may be the maximum brightness associated with the projector 125 or a maximum source brightness set by the user). In a second power mode, the projector 125 does not project any image 130. In a third mode, the projector 125 projects the image 130 at a lower brightness, for example, 25-50% of full brightness. In one situation, the projector controller 135 can place the projector 125 in the second low-power mode after, for example, a door is unlocked, and then place the projector 125 back into the first low-power mode after a predetermined period of time (e.g., two minutes). When trigger device 420 is activated, for example, by a restroom door being opened, projector controller 135 can command projector 125 to transition from the first low-power mode to the second low-power mode. Projector controller 135 can then command projector 125 to enter normal projection mode when a signal is received from sensor 305 indicating that the door is locked.

[0051] Although the changing table 605 shown in Figures 7A-7C is oriented horizontally, the changing table 605 can also be oriented vertically so that when unfolded, the baby 735 will lie perpendicular to the wall 705 rather than parallel to it.

[0052] 8A-8B show a side view 800 of a changing table 605 including a transparent display 105 (shown in FIG. 1) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). In FIG. 8A, the view 800 includes a cutaway view of the changing table 605 in a stowed or up position. In FIG. 8B, a view 825 represents a close-up view of the changing table 605 in a stowed or up position. The view 800 includes a latch mechanism 805 for securing the changing table 605 in the stowed or up position. The latch mechanism 805 may include one or more sensors 305 (shown in FIG. 3) that indicate the current state of the latch mechanism 805.

[0053] When the changing table 605 is in the stowed or up position, the projector 125 transmits one or more images 130 through a lens 710 in the wall 705. The images 130 are projected onto the projection surface 115 of the semi-transparent projection area 720 of the changing table 605. The images 130 are then displayed on the display surface 110 of the semi-transparent projection area 720 of the changing table 605.

[0054] 9A-9B show a side view 900 of a changing table 605 including a transparent display 105 (shown in FIG. 1) using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). In FIG. 9A, view 900 includes a cutaway view of the changing table 605 in the unfolded or down position. In FIG. 9B, view 925 depicts a close-up view of the changing table 605 in the unfolded or down position.

[0055] When the changing table 605 is in the extended or down position, the projector 125 does not transmit the image 130 (not shown). Although the lens 710 is visible in the wall 705, the projector 125 is hidden and the user of the changing table 605 as a projector can only reach behind the wall 705.

[0056] Figure 10A shows a top-down view 1000 of another configuration of the translucent display 105 (shown in Figure 1) on the changing table 605. Figure 10B shows a side view 1025 of another configuration of the translucent display 105 (shown in Figure 1) on the changing table 605.

[0057] Depending on the projector 125 used and / or the duration of continuous use of the projector 125, the temperature of the lens 710 may increase to a point where the lens 710 may be harmful to individuals touching the lens 710. Furthermore, in many situations, available space in restrooms is limited, and therefore, it may be necessary to move or rearrange the configuration of components of the transflective display 105 to address the above issues.

[0058] As shown in FIGS. 1000 and 1025, projector 125 is positioned parallel to wall 705. Projector 125 projects image 130 onto mirror 1005, which is positioned on the projection side 1010 of wall 705. Mirror 1005 is attached using one or more fixing devices, such as a bracket. Mirror 1005 is secured in a fixed position to prevent movement of mirror 1005 and distortion of image 130. Mirror 1005 directs image 130 through lens 710 onto projection surface 115 of translucent projection area 720 of changing table 605, with image 130 on viewing side 1015 of wall 705. While the mirror is shown at a 45-degree angle and projector 125 is shown parallel to wall 705, both of these angles can be changed based on the desired configuration. Additionally, projector 125 can be placed above, below, or to the side of lens 710 depending on the available space and desired configuration.

[0059] 11 shows a diagram 1100 of a translucent display 105 on a changing table 605 using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). Diagram 1100 shows the display surface 110 (shown in FIG. 1) of the translucent display 105 on the changing table 605 in a stowed or up position. The display surface 110 is displaying an image 130 (shown in FIG. 1) instructing a viewer 120 (shown in FIG. 1) to return to their seat, such as in an aircraft restroom.

[0060] FIG. 12 shows a further view of a restroom 1200 using projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively). The restroom 1200 includes a plurality of walls 705 and a floor 1210. The walls 705 and floor 1210 may include the projector system 300. The restroom 1200 also includes a sink 1215 and a toilet bowl 1220. The sink 1215 may be similar to the sink area 410 (see FIG. 4). The toilet bowl 1220 includes a toilet lid 1225, a toilet seat 1230, and a toilet shroud 1235. The toilet bowl 1220 is associated with a toilet flush button 1240. The restroom 1200 also includes a folded-down changing table 605.

[0061] 13 illustrates a process 1300 for utilizing a restroom-based projector system according to at least one embodiment. In one example, process 1300 is implemented by at least one of projector controller 135 (shown in FIG. 1) and projector controller computing device 310 (shown in FIG. 3) programmed to control restroom 1200 (shown in FIG. 12) that includes multiple translucent displays 105 (shown in FIG. 1). In one example, the restroom 1200 may have a translucent display 105 positioned on a surface such as, but not limited to, the counter 405, the sink area 410, the splash guard area 415 (all of which are shown in FIG. 4A), the changing table 605 (shown in FIG. 6), the wall 705 (shown in FIG. 12), or on other surfaces including, but not limited to, the toilet bowl 1220, the toilet lid 1225, the toilet seat 1230, the toilet shroud 1235, the wall 705, the floor 1210 (all of which are shown in FIG. 12), the ceiling, a cabinet surface, and any other visible surface within the restroom 1200. Although process 1300 describes the use of projector systems 100, 200, and 300 (shown in FIGS. 1, 2, and 3, respectively) in a restroom setting, the systems and methods described herein can also be used in vehicles, such as, but not limited to, aircraft, ships, trains, buses, and spacecraft, and on other surfaces within the vehicle, such as, but not limited to, passenger seats (e.g., tray tables), galleys (e.g., work decks and sinks), passenger aisles (e.g., ceilings, floors, walls), counter units (e.g., counters and reception areas), and any other visible surface of the vehicle. Furthermore, the systems and methods could also be applied to other environments, such as, but not limited to, bathrooms, kitchens, dining rooms, and other public areas of homes and businesses (or hotels). Although a diaper changing table is utilized herein as an exemplary implementation, reading this specification will recognize that other implementations and applications are within the scope of this disclosure, including, but not limited to, other foldable support surfaces, such as trays, tables, and workspaces, among others.

[0062] In process 1300, a user enters restroom 1200 and locks the door (1305). Locking the door (1305) triggers first trigger device 420 (shown in FIG. 4A ), which causes projector controller 135 to activate (1310) a first projection sequence on a particular translucent display 105, such as, but not limited to, a wall 705, a ceiling, a floor 1210, a changing table 605, and a cabinet surface. A projection sequence is an image, multiple images, and / or video projected onto one or more translucent displays 105. As used herein, first projection sequence, second projection sequence, and third projection sequence refer to different sequences of images or video. Furthermore, the different sequences may be projected onto the same translucent display 105 or different translucent displays 105. In some examples, the first projection sequence ends and continues to display images, such as the last image of the first projection sequence. In other examples, the first projection sequence repeats until interrupted by a specific user action. When projector controller 135 receives a signal from the door lock that the door is locked (1305) and a signal from a motion sensor or any other sensor 305 (shown in FIG. 3) that projector controller 135 should activate the first display sequence, projector controller 135 commands one or more projectors 125 (shown in FIG. 1) to display the first projection sequence.

[0063] A second projection sequence is activated 1320 by a user triggering 1315 the toilet flush button 1240 (shown in FIG. 12 ). The second projection sequence may differ from the first projection sequence in the content of the projection sequence and / or the location on the translucent display 105 on which the second projection sequence is displayed. The second projection sequence may be displayed on one or more of the diaper changing table 605, the toilet bowl 1220, the toilet lid 1225, the toilet seat 1230, and the toilet shroud 1235. The second projection sequence may be projected onto the same surface as the first projection sequence. The second projection sequence may be activated 1320 after the toilet flush button 1240 is triggered 1315 and the toilet lid 1225 and / or the toilet seat 1230 are returned to the down position. The projector controller 135 receives a signal that the toilet flush button 1240 has been triggered (1315), and the projector controller 135 commands one or more projectors 125 to project a second projection sequence. The flush sensor 305 may be separate from the toilet flush button 1240, and the flush sensor 305 detects when a flush occurs, for example, in the case of an automatic flushing toilet. The second projection sequence may be displayed on any combination of the transparent displays 105 listed above in response to one or more of the above-mentioned triggers.

[0064] When a user triggers the faucet (1325), for example, by triggering the faucet sensor or trigger device 420 (shown in FIG. 4A ), a third projection sequence is activated (1330). The third projection sequence may be projected onto one or more of the counter 405, the sink area 410, and the splash guard area 415. The third projection sequence may also be projected onto the same surface as at least one of the first and second projection sequences. The projector controller 135 receives a signal that the faucet sensor or trigger device 420 has been triggered (1325), and the projector controller 135 commands one or more projectors 125 to display the third projection sequence. Like the second projection sequence, the third projection sequence may be displayed on any combination of the transparent displays 105 listed above in response to one or more of the above-mentioned triggers.

[0065] When a user triggers the automatic paper towel dispenser (1335), a fourth projection sequence is activated (1340). The fourth projection sequence may be displayed on one or more of the counter 405, the sink area 410, and the splash guard area 415. The fourth projection sequence may also be projected onto the same surface as at least one of the first projection sequence, the second projection sequence, and the third projection sequence. The projector controller 135 receives a signal that the automatic paper towel dispenser has been triggered (1335), and the projector controller 135 commands one or more projectors 125 to project the fourth projection sequence. The fourth projection sequence may be displayed on any combination of the transparent displays 105 listed above in response to one or more of the above-mentioned triggers.

[0066] The different sequences may be triggered in different orders based on user actions. Additionally, one or more sequences may be triggered based on additional sensors 305 present in the restroom 1200 that may trigger other projection sequences.

[0067] Projector controller 135 can continue to display one or more sequences until the user unlocks the door. Projector controller 135 can continue to display one or more sequences for a predetermined period of time after the door is unlocked.

[0068] Projector controller 135 can also continuously display one or more images or videos in a low power state, where images are projected at a lower illumination level until the door is locked.

[0069] The projector controller 135 may also interrupt any projection sequence to display an important message, such as the return to seat images shown in FIGS. 5 and 11, or other appropriate information or instructions, and may provide a visual indication that a patron in the restroom has pressed the attendant call button, and the translucent display 105 may show an image / message that an attendant has been called.

[0070] 14 illustrates a process 1400 for utilizing a restroom-based projector system including a changing table 605 (shown in FIG. 6) according to at least one embodiment. Process 1400 is implemented by at least one of projector controller 135 (shown in FIG. 1) and projector controller computing device 310 (shown in FIG. 3) programmed to control restroom 1200 (shown in FIG. 12) including multiple translucent displays 105 (shown in FIG. 1). Restroom 1200 includes translucent displays 105 disposed at the changing table 605. Restroom 1200 may have translucent display 105 disposed on other surfaces, such as, but not limited to, counter 405, sink area 410, splash guard area 415 (all shown in FIG. 4A ), wall 705 (shown in FIG. 7 ), or on other surfaces, including, but not limited to, toilet bowl 1220, toilet lid 1225, toilet seat 1230, toilet shroud 1235, wall 1205, floor 1210 (all shown in FIG. 12 ), ceiling, cabinet surface, and any other visible surface within restroom 1200. While process 1400 describes the use of projector systems 100, 200, and 300 (shown in FIGS. 1 , 2, and 3 , respectively) in a restroom setting, the systems and methods described herein may also be used in, for example, but not limited to, aircraft, ships, trains, buses, and spacecraft.

[0071] Process 1400 is a variation on process 1300 (shown in FIG. 13). In process 1300, a user enters restroom 1200 and locks the door (1305). Locking the door (1305) triggers first trigger device 420 (shown in FIG. 4A), which causes projector controller 135 to activate (1310) a first projection sequence on a particular translucent display 105, such as, but not limited to, a wall 705, a ceiling, a floor 1210, a changing table 605, and a cabinet surface. A projection sequence is an image, multiple images, and / or video projected onto one or more translucent displays 105. As used herein, first projection sequence, second projection sequence, and third projection sequence refer to different sequences of images or video. Additionally, different sequences can be projected on the same translucent display 105 or different translucent displays 105. A first projection sequence can end and continue to display images, such as the last image of the first projection sequence. The first projection sequence repeats until interrupted by a specific user action. When projector controller 135 receives a signal from the door lock that the door is locked (1305) and a signal from a motion sensor or any other sensor 305 (shown in FIG. 3) that projector controller 135 should activate the first display sequence, projector controller 135 commands one or more projectors 125 (shown in FIG. 1) to display the first projection sequence.

[0072] In process 1400, a user enters restroom 1200 and locks the door (1405). Locking the door (1405) triggers first trigger device 420 (shown in FIG. 4A ), which causes projector controller 135 to activate (1410) a first projection sequence on a particular translucent display 105, such as, but not limited to, a wall 705, a ceiling, a floor 1210, a changing table 605, and a cabinet surface. A projection sequence is an image, multiple images, and / or video projected onto one or more translucent displays 105. Herein, the terms first projection sequence, second projection sequence, and third projection sequence refer to different sequences of images or video. Furthermore, the different sequences can be projected onto the same translucent display 105 or different translucent displays 105. After the first projection sequence ends, it is possible to continue displaying an image, such as the last image of the first projection sequence. The first projection sequence repeats until interrupted by a specific user action. When projector controller 135 receives a signal from the door lock that the door is locked (1405) and a signal from the motion sensor or any other sensor 305 (shown in FIG. 3) that the projector controller 135 should activate the first display sequence, projector controller 135 commands one or more projectors 125 (shown in FIG. 1) to display the first projection sequence. Projector controller 135 can also interrupt any projection sequence to display an important message, such as the return-to-your-seat images shown in FIGS. 5 and 11, or other appropriate information or instructions; for example, a visual indication can be provided that a lavatory patron has pressed the attendant call button, and translucent display 105 can show an image / message that an attendant has been called.

[0073] The projector 125 associated with the changing table 605 is currently projecting one or more images 130 onto the changing table 605. A user unfolds or lowers the changing table 605 (1415). One or more sensors 305 associated with the changing table 605 signal the projector controller 135 that the changing table 605 is no longer fully in the stowed or up position (1420). The projector controller 135 commands the projector 125 associated with the changing table 605 to stop projecting images. The projector controller 135 commands the projector 125 to stop projecting as soon as it determines that the changing table 605 is no longer fully in the stowed or up position, thereby causing the projector 125 to stop projecting before the changing table 605 is in the fully down position. This timing reduces the chance of the projector projecting into the user's eyes and / or face. The sensors 305 associated with the changing table 605 include, but are not limited to, proximity switches, magnetic switches, level switches, tilt / displacement switches, radial switches, mercury switches, latching switches, or any other switch or sensor that indicates the current position of the changing table 605.

[0074] While the changing table 605 is in the extended or down position, a user can place (1425) a baby on the changing table 605 and tend to the baby's needs. The user removes (1430) the baby from the changing table 605 and closes or raises (1435) the changing table 605 to return it to the stowed or up position. A sensor 305 associated with the changing table 605 notifies (1440) the projector controller 135 that the changing table 605 has returned to the stowed or up position.

[0075] The projector controller 135 commands the projector 125 associated with the changing table 605 to resume the projection sequence it was projecting, such as the first projection sequence. The projector 125 can resume the projection sequence from the point where the sequence was stopped. The projector controller 135 can also synchronize the projector 125 associated with the changing table 605 with the other translucent displays 105. For example, while the projector 125 associated with the changing table 605 stopped projecting the first projection sequence, the other active projectors 125 in the restroom 1200 continued to project the first projection sequence. When the changing table 605 is returned to the stowed position or the up position, the projector controller 135 commands the projector 125 associated with the changing table 605 to begin projecting the first projection sequence from the same point in the sequence where the other projectors 125 are currently projecting.

[0076] If projector controller 135 determines 1445 that the door is locked or that no motion has been detected for a predetermined period of time, projector controller 135 commands projector 125 to enter sleep mode. When in sleep mode, projector 125 may stop projecting image 130. When in sleep mode, projector 125 may also continue to project image 130 at a lower brightness (25-50% of full brightness).

[0077] 15 illustrates another process 1500 for utilizing a restroom-based projector system including a changing table 605 (shown in FIG. 6) according to at least one embodiment. Process 1500 is implemented by at least one of projector controller 135 (shown in FIG. 1) and projector controller computing device 310 (shown in FIG. 3) programmed to control restroom 1200 (shown in FIG. 12) including multiple translucent displays 105 (shown in FIG. 1). Restroom 1200 includes translucent displays 105 disposed at the changing table 605. Restroom 1200 may have translucent display 105 disposed on other surfaces, such as, but not limited to, counter 405, sink area 410, splash guard area 415 (all shown in FIG. 4A ), wall 705 (shown in FIG. 7 ), or other surfaces, including, but not limited to, toilet bowl 1220, toilet lid 1225, toilet seat 1230, toilet shroud 1235, wall 1205, floor 1210 (all shown in FIG. 12 ), ceiling, cabinet surface, and any other visible surface within restroom 1200. While process 1500 describes the use of projector systems 100, 200, and 300 (shown in FIGS. 1 , 2, and 3 , respectively) in a restroom setting, the systems and methods described herein may also be used in, for example, but not limited to, aircraft, ships, trains, buses, and spacecraft.

[0078] In process 1500, the projector controller computing device 310 receives (1505) a first signal from a first sensor 305 (shown in FIG. 3). The first sensor 305 may include any sensor 305, such as, but not limited to, a door lock sensor, a wash sensor, a faucet sensor, a motion sensor, a heat sensor, and an automatic paper towel dispenser sensor. In response to the first signal from the first sensor 305, the projector controller computing device 310 determines (1510) a first projection sequence to display. The projection sequence is an image, multiple images, and / or video to be projected onto one or more translucent displays 105. The projector controller computing device 310 determines (1515) a first translucent display 105 (shown in FIG. 1) and a corresponding first projector 125 (shown in FIG. 1) for displaying the first projection sequence. The first translucent display is a diaper changing table 605. Projector controller computing device 310 sends (1520) instructions to first projector 125 to project a first projection sequence onto projection surface 115 (shown in FIG. 1 ) of diaper changing table 605. This causes the first projection sequence to be displayed on display surface 110 (shown in FIG. 1 ) of diaper changing table 605. Projection surface 115 is the side of first diaper changing table 605 opposite display surface 110 of diaper changing table 605. Projector 125 inverts image 130 and projects it onto projection surface 115, thereby allowing image 130 to be displayed on display surface 110 in the correct orientation relative to viewer 120.

[0079] The projector controller computing device 310 receives 1525 a second signal from a second sensor 305. The second sensor 305 is associated with the changing table 605 and indicates the current position of the changing table 605. The second sensor 305 associated with the changing table 605 may include, but is not limited to, a proximity switch, a magnetic switch, a level switch, a tilt / displacement switch, a radial switch, a mercury switch, a latching switch, or any other switch or sensor that indicates the current position of the changing table 605.

The second signal may indicate that the changing table 605 is open, or even that a latch holding the changing table 605 in the stowed position is open. The projector controller computing device 310 sends (1535) a command to the first projector 125 to stop projecting the first projection sequence.

[0081] The projector controller computing device 310 receives a third signal from the second sensor indicating that the changing table 605 is in the stowed position. The projector controller computing device 310 sends a command to the first projector to resume projecting the first projection sequence.

[0082] The projector controller computing device 310 may send instructions to the first projector 125 and a second projector 125 associated with the second translucent display 105 to display the first projection sequence on the display surfaces 110 of the first translucent display 105 and the second translucent display 105. The second translucent display 105 is different from the first translucent display 105. In response to the second signal, the projector controller computing device 310 sends instructions to the first projector 125 to stop projecting the first projection sequence, while the second projector 125 continues to project the first projection sequence on the second translucent display 105. The projector controller computing device 310 synchronizes the display of the first projection sequence by the first projector 125 and the display of the first projection sequence by the second projector 125 so that the two projectors 125 project the same image simultaneously. The second translucent display 105 may include a wall 705 , a counter 405 , a ceiling, a floor 1210 , a cabinet surface, a splash guard area 415 , a sink area 410 , a toilet bowl 1220 , a toilet shroud 1235 , a toilet seat 1230 , and a toilet lid 1225 .

[0083] The projector controller computing device 310 may receive a third signal indicating that the door has been unlocked from the first sensor 305. The projector controller computing device 310 may then instruct the first projector 125 to activate a sleep mode.

[0084] The projector controller computing device 310 receives a signal from the at least one sensor 305 indicating that the changing table 605 is in the stowed position. The projector controller computing device 310 commands the projector 125 to project at least one image 130 onto the translucent display 105. The projector controller computing device 310 receives a signal from the at least one sensor 305 indicating that the changing table 605 is no longer in the stowed position. The projector controller computing device 310 commands the projector 125 to stop projecting the at least one image 130. The projector controller computing device 310 receives a signal from the at least one sensor 305 indicating that the changing table 605 has returned to the stowed position. The projector controller computing device 310 commands the projector to resume projecting the at least one image.
