Abstract
Abstract A method and apparatus for scanning a fingerprint using a linear optical sensor. A finger or palm is rolled over a transparent roller. A light source directs light through the roller to illuminate or detect the finger. Light directed through the roller is focused onto a linear imaging device. A full 2D recreation of the fingerprint is assembled from the discrete line-image data collected by the linear array imaging sensor. The apparatus contains a rotation detector to detect rotational movement of the roller.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
72 words
An apparatus for a cursor control device that may be used for scanning a fingerprint comprising: a roller for controlling a display; and a fingerprint scanning device comprising: a linear imaging device; a light source positioned to direct light through the roller; a focusing device positioned to focus light directed through the roller onto the linear imaging device; such that the roller is used to control a cursor and for fingerprint scanning.
Claim 2
Independent Claim
72 words
An apparatus for a cursor control device that may be used for scanning a fingerprint comprising: a roller for controlling a display; and a fingerprint scanning device comprising: a linear imaging device; a light source positioned to direct light through the roller; a focusing device positioned to focus light directed through the roller onto the linear imaging device; such that the roller is used to control a cursor and for fingerprint scanning.
Claim 3
Dependent Claim
18 words
The apparatus of claim 1 , further comprising a rotation detector to detect rotational movement of the roller.
Claim 4
Dependent Claim
43 words
The apparatus of claim 2 , wherein the rotation detector comprises: a slotted wheel coupled to the roller; a second light source positioned to direct light through the slotted wheel; and a light detector positioned to detect light directed through the slotted wheel.
Claim 5
Dependent Claim
24 words
The apparatus of claim 2 , wherein the rotation detector comprises: roller indicia; and an indicia detector positioned to detect movement of the indicia.
Claim 6
Dependent Claim
15 words
The apparatus of claim 4 , wherein the indicia detector comprises the linear imaging device.
Claim 7
Dependent Claim
27 words
The apparatus of claim 4 , wherein the roller indicia comprises markings selected from the group consisting of bumps, pits, ridges, slots, optical decals, and optical marks.
Claim 8
Dependent Claim
16 words
The apparatus of claim 1 , further comprising a finger guide positioned adjacent to the roller.
Claim 9
Dependent Claim
35 words
The apparatus of claim 1 , wherein controlling the cursor comprises using the roller as a scrolling and zooming wheel that provides universal scrolling in applications directly from the cursor control device without using scrollbars.
Claim 10
Dependent Claim
13 words
The apparatus of claim 1 , wherein the roller controls cursor movement directly.
Claim 11
Dependent Claim
45 words
The apparatus of claim 9 , wherein the linear image device recognizes a movement of the finger on the roller, and further comprising a cursor control software for determining an appropriate movement of the cursor based on the movement of the finger on the roller.
Claim 12
Dependent Claim
24 words
The apparatus of claim 1 , wherein the apparatus is embedded in one of the following devices: a mouse, a trackball, or a keyboard.
Claim 13
Dependent Claim
23 words
The apparatus of claim 1 , further comprising software for recognizing an area requesting authentication information and prompting a user for the fingerprint.
Claim 14
Dependent Claim
28 words
The apparatus of claim 12 , wherein the software further comprises: light control for lighting up the roller when the cursor is over the area requesting authentication information.
Claim 15
Dependent Claim
29 words
The apparatus of claim 12 , wherein the software further comprises: an authentication inserter for inserting authentication information into the area requesting authentication information based on the user's fingerprint.
Claim 16
Independent Claim
70 words
A method for using a cursor control device for scanning a fingerprint comprising: controlling a cursor in response to movement of a roller; determining if the cursor is over an authentication area; and if the cursor is over an authentication area: lighting up the roller; and illuminating a finger with light directed through the roller; and capturing an image of the fingerprint through the roller with a linear imaging device.
Claim 17
Independent Claim
70 words
A method for using a cursor control device for scanning a fingerprint comprising: controlling a cursor in response to movement of a roller; determining if the cursor is over an authentication area; and if the cursor is over an authentication area: lighting up the roller; and illuminating a finger with light directed through the roller; and capturing an image of the fingerprint through the roller with a linear imaging device.
Claim 18
Dependent Claim
25 words
The method of claim 15 , further comprising: recognizing the fingerprint; and inserting an appropriate authentication information in the authentication area, based on the fingerprint.
Claim 19
Dependent Claim
58 words
The method of claim 16 , wherein inserting comprises: determining whether the authentication area requests fingerprint data or other data; and inserting fingerprint data into the authentication area if the authentication area requests fingerprint data; and looking up other data in a memory if the authentication area requests other data, and inserting other data into the authentication area.
Claim 20
Dependent Claim
38 words
The method of claim 15 , further comprising: recognizing a fingerprint received from the linear imaging device; determining whether the fingerprint is associated with a function; and if the fingerprint is associated with a function, performing the function.
