This application claims priority under U.S.C. §120 from co-pending U.S. patent application Ser. No. 10/891,840, filed Jul. 15, 2004 and entitled, “POSITIONABLE PROJECTION DISPLAY DEVICES”, which is incorporated herein for all purposes; the Ser. No. 10/891,840 patent application also claimed priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,868 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,871 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,691 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,849 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes; this application also claims priority under 35 U.S.C. §119(e) from co-pending U.S. Provisional Patent Application No. 60/487,744 filed Jul. 16, 2003, which is incorporated by reference herein for all purposes.
Projection chamber 14 comprises a projection chamber housing 32 that protects internal components of projection chamber 14; and defines outer and inner dimensions of projection chamber 14. As shown, housing 32 is about cylindrical, except for an added receiving interface 29 on its bottom side. Housing 32 has a cylindrical axis that is about collinear with output projection path 31. An output optical projection lens 37 of the projection lens system forms and seals a forward end 14a of projection chamber 14. In a specific embodiment, the average diameter of cylindrical housing 32 is relatively within 10 percent of the diameter of output lens 37. In another embodiment, projection chamber housing 32 tapers slightly such that forward end 14a is slightly larger than an aft end 14b, resulting in a slightly frustoconical shape where lens 37 constitutes the larger end. The present invention contemplates that shape and design of projection chamber 14 may vary. For example, forward end 14 a of projection chamber 14 may be rounded to accommodate a circular output lens 37 while aft end 14 b is cornered to accommodate a rectangular optical modulation device and associated support components that are locally contained better by a rectangular housing. Housing 32 defines an inner chamber as described in further detail with respect to FIG. 3A. Housing 32 comprises a suitably stiff material for structural rigidity of base 12 and internal component protection. A lightweight and stiff plastic or aluminum is suitable for most designs.
at least one battery that stores electrical energy; and
an electrical energy transport system configured to transmit electrical energy from the battery to the light source and to transmit electrical energy from the battery to the optical modulation device.
4. The display device of claim 1 wherein the at least one battery stores a maximum of 200 watt hours of electrical energy.
5. The display device of claim 4 wherein the at least one battery stores a maximum of 100 watt hours of electrical energy.
7. The display device of claim 6 wherein each diode laser in the array consumes less than about 10 watts when generating light.
8. The display device of claim 1 further comprising a fan that moves cooling air through internal portions of the display device and receives electrical energy from the battery via the electrical energy transport system.
10. The display device of claim 1 wherein the display device is configured to consume less than about 50 watt s when producing light and projecting an image.
a base that includes a) a housing, b) a light source within the housing for generating light, and c) at least one battery within the housing that stores electrical energy;
a projection chamber that includes a) a projection chamber housing, b) an optical modulation device configured to selectively transmit light generated by the light source according to video data included in a video signal provided to the optical modulation device, and c) a projection lens system for outputting light, transmitted by the optical modulation device, along a projection path;
a positional interface, coupled to the base and coupled to the projection chamber, that allows the projection chamber to be moved relative to the base and allows the projection chamber to maintain a constant position relative to the base after being moved; and
14. The display device of claim 11 wherein the at least one battery stores a maximum of 200 watt hours of electrical energy.
15. The display device of claim 14 wherein the at least one battery stores a maximum of 100 watt hours of electrical energy.
17. The display device of claim 16 wherein each diode laser in the array consumes less than about 10 watts when generating light.
20. The display device of claim 11 wherein the display device is configured to consume less than about 50 watt s when producing light and projecting an image.
