Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
114 words
A communications device having first and second modes of operation, where in the first mode of operation a display built into the device displays information for direct viewing by a user, and where in the second mode of operation the display built into the device projects information onto a reflective surface for viewing by the user, wherein the first mode of operation the display displays the information at such a size that the information is legible when viewed directly by the user, and wherein the second mode of operation the display projects the information onto the reflective surface at a size larger than when the information is displayed for direct viewing by the user.
Claim 2
Dependent Claim
114 words
A communications device having first and second modes of operation, where in the first mode of operation a display built into the device displays information for direct viewing by a user, and where in the second mode of operation the display built into the device projects information onto a reflective surface for viewing by the user, wherein the first mode of operation the display displays the information at such a size that the information is legible when viewed directly by the user, and wherein the second mode of operation the display projects the information onto the reflective surface at a size larger than when the information is displayed for direct viewing by the user.
Claim 3
Dependent Claim
32 words
The communications device as recited in claim 1 , wherein the information projected onto the reflective surface appears as if it were being displayed by a display device larger than the display.
Claim 4
Dependent Claim
47 words
The communications device as recited in claim 1 , wherein the first mode of operation the display is viewable by the user through a window in a cover while in a closed position, and wherein the second mode of operation the cover is in an open position.
Claim 5
Dependent Claim
26 words
The communications device as recited in claim 3 , wherein the information is also viewable directly by the user with the cover in the open position.
Claim 6
Dependent Claim
30 words
The communications device as recited in claim 1 , further comprising an input device that permits input by the user when in either the first or second modes of operation.
Claim 7
Dependent Claim
28 words
The communications device as recited in claim 1 , wherein the device is a telephone that permits the user to conduct a conversation while also viewing the display.
Claim 8
Dependent Claim
128 words
A personal communications device comprising: a main body having a built in display; a cover hingably attached to the main body, wherein the display is viewable by a user through an opening in the cover when the cover is in a closed position with respect to the main body; a reflective surface attached to the main body for reflecting images projected by the display when the cover is in an open position with respect to the main body; and wireless telephone circuitry for permitting the user to conduct a telephone conversation, including a speaker in the cover and a microphone, wherein the user can view the images projected onto the reflective surface while holding the device to a side of the user's face to conduct the telephone conversation.
Claim 9
Dependent Claim
128 words
A personal communications device comprising: a main body having a built in display; a cover hingably attached to the main body, wherein the display is viewable by a user through an opening in the cover when the cover is in a closed position with respect to the main body; a reflective surface attached to the main body for reflecting images projected by the display when the cover is in an open position with respect to the main body; and wireless telephone circuitry for permitting the user to conduct a telephone conversation, including a speaker in the cover and a microphone, wherein the user can view the images projected onto the reflective surface while holding the device to a side of the user's face to conduct the telephone conversation.
Claim 10
Dependent Claim
41 words
The device as recited in claim 7 , wherein the reflective surface and the display are both hingably attached to the main body and are hinged to open positions for projection of the images from the display to the reflective surface.
Claim 11
Dependent Claim
36 words
The device as recited in claim 8 , wherein the images are rotated 90 degrees when projected onto the reflective surface from an orientation when displayed by the display when it is in a closed position.
Claim 12
Dependent Claim
25 words
The device as recited in claim 7 , further comprising: an input device for moving and selecting items displayed on the display by the user.
Claim 13
Dependent Claim
139 words
A personal communication device comprising a dual mode display for a user's viewing in both a direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification, and in “projection view” mode, wherein more content can be displayed over that of the direct view mode; and a tri mode display for a user's viewing in both an open direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification when a lid is in an open position, a closed direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification when the lid is in a closed position, and in “projection view” mode, wherein more content can be displayed over that of direct view mode.
Claim 14
Dependent Claim
139 words
A personal communication device comprising a dual mode display for a user's viewing in both a direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification, and in “projection view” mode, wherein more content can be displayed over that of the direct view mode; and a tri mode display for a user's viewing in both an open direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification when a lid is in an open position, a closed direct view mode, wherein sufficiently sized characters are displayed in a manner visible to the user without further magnification when the lid is in a closed position, and in “projection view” mode, wherein more content can be displayed over that of direct view mode.
