20160162722
A body-part relief image scanning device (scanner), such as a fingerprint recognition device, is used for a variety of purposes including security. A person's body-part can contact a surface of the scanner, where an image may be captured of the body-part, such as a finger print or some other biometric marker. The resulting image may be compared to a database of body-part images to verify the person's identity, for example. A body-part relief print image device may use an electrode-based, electro-luminescence component that can utilize an electrical connection between a relief object and the electro-luminescence component.
This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key factors or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.
Accordingly, among other things, one or more techniques and/or systems are disclosed for mitigating a perceived electric shock to a user of a body-part relief print image device. As an example, a base current (e.g., an electrical current having a first current configuration) may be used to capture an initial image (e.g., a first image) of the body-part relief print, and, if based on an analysis of the resulting image, one or more subsequent images may be captured using modified current characteristics.
In one implementation, where a perceived electrical sensation may be mitigated for a relief print scanning device, a current determination component can identify a desired current configuration for electrical current that is provided to an electroluminescent-based relief print scanning device. In this implementation, the desired current configuration can be identified based on a first image characteristic of a first relief print image, where the first relief print image may be provided by the relief print scanning device while utilizing a first current configuration of the electrical current. Further, in this implementation, a current adjusting component, which is operably coupled with the current determination component, may adjust the first current configuration to a second current configuration; where the adjustment can be based on current adjustment data that is provided by the current determination component.
To the accomplishment of the foregoing and related ends, the following description and annexed drawings set forth certain illustrative aspects and implementations. These are indicative of but a few of the various ways in which one or more aspects may be employed. Other aspects, advantages and novel features of the disclosure will become apparent from the following detailed description when considered in conjunction with the annexed drawings.
The claimed subject matter is now described with reference to the drawings, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate describing the claimed subject matter.
A user of a relief print scanner, for example, that comprises an electro-luminescent based film, typically places their finger on the surface of the scanner in contact with both the surface film and a contact electrode. As a non-limiting example, the contact electrode can be a source of electrical current that may be used to activate the electro-luminescent particles in the film, where the electrical current passes through the user's finger to the surface film. In one implementation, an electro-luminescent-based relief print scanning device may comprise an electro-luminescent based film that operates in a voltage range of about sixty to about six hundred volts (e.g., 60-600 VAC), inclusive. In this example, a user of this type of scanner may perceive an electrical sensation (e.g., electrical shock), which, in some instances, may be somewhat uncomfortable. In one implementation, the perceived electrical sensation may be reduced by reducing one or more characteristics of the electrical current (e.g., voltage and/or frequency), thereby improving the user's comfort during use.
In one implementation, the relief print generator 102 may comprise an electrode-based (e.g., single electrode), electro-luminescence component 106, and/or an electrical connection 108 (e.g., a power source, such as an A/C source), which may provide an electrical connection between a relief object 118 and the electro-luminescence component 106. Further, in one implementation, the electrode-based, electro-luminescence component 106 may comprise a transparent electrode 110 (e.g., comprising an indium tin oxide (ITO) material, which may be attached to a polymer substrate), a luminescent layer 112, and/or a dielectric layer 114 (e.g., a conductive/insulating layer that allows current to pass). In one implementation, the relief print generator 102 and the sensor arrangement 104 may be separated at a distance 116 to each other or may be arranged such that the sensor arrangement 104 is in contact with the relief print generator 102. As one example, when a relief print recognition system is activated (e.g., by placing a finger at an image capture location), light produced by the luminescent layer 106 is emitted in respective directions, such as directed toward the sensor arrangement 104.

In one implementation, a relief object 244 may contact both the contact surface of the dielectric layer 210 and the contact electrode 218. In this implementation, for example, upon contacting both the dielectric layer 210 and the object contact electrode 218, an electrical circuit may be created between the contact electrode 218 and the transparent electrode 212, thereby allowing current 246 to flow between the two electrodes. Further, in this implementation, those portions of the relief object 244 (e.g., body-part relief ridges) that come in contact with the contact surface of the dielectric layer 210 can allow current 246 to pass from the contact electrode 218 to the dielectric layer 210. Additionally, the current 246 passing through the dielectric layer can activate the fluorescent particles 204 merely at the location of the contact. Upon activation, the activated particles 208 may emit photons 242 merely at the location of the contact of the portions of the relief object 244 (e.g., fingerprint ridges). In this way, for example, an illuminated relief print (e.g., fingerprint) of the relief object 244 (e.g., finger) may be produced when the relief object 244 contacts both the contact electrode 218 and the contact surface of the dielectric layer 210.
As shown in
In the example implementation 250, a photo-sensitive layer 256 (e.g., comprising SiH, amorphous silicon) may be formed between a first source electrode 258 and a first drain electrode 260 of a light sensing unit 262. When an electrical charge is applied to a first gate electrode 264, the photo-sensitive layer 256 becomes responsive to light, for example, where the photo-sensitive layer 256 may become electrically conductive when incident to photons of light. As one example, when light is incident on the photo-sensitive layer 256 over a predetermined, threshold light amount, the first source electrode 258 and the first drain electrode 260 may become electrically connected. Therefore, in this example, light generated from the light emitting component 254 (e.g., comprising a fingerprint pattern) may be received by the photo-sensitive layer 256, which may cause an electrical signal to pass from the first source electrode 258 to the first drain electrode 260 (e.g., providing an electronic signal indicative of the light received).
Further, a switching unit 266 of the image sensor portion 252 can comprise a second source electrode 268, a second drain electrode 270 and an intrinsic semiconductor layer 272. As one example, when a negative charge is applied to a second gate electrode 274, the intrinsic semiconductor layer 272 may become electrically conductive, thereby allowing the electrical signal created at the light sensing unit 262 to pass from the second source electrode to the second drain electrode (e.g., and to an electrical signal reading component for converting to a digital image). In this way, for example, the switching unit 266 may be used to control when an electrical signal indicative of a particular amount of light may be sent to an electrical signal reading component (e.g., for processing purposes and/or to mitigate signal interference with neighboring light sensing units).
Additionally, in this implementation 250, a light shielding layer 282 may be resident over the top portion of the switching unit 266. As one example, the light shielding layer 282 may mitigate intrusion of light to the intrinsic semiconductor layer 272, as light can affect the electrical conductivity of the intrinsic semiconductor layer 272. The image sensor portion 252 may also comprise a substrate 284 of any suitable material, onto which the layers of the image sensor portion 252 may be formed. As one example, when a relief object 276 (e.g., 244 of
In the implementations 320, 350 and 370, the contact electrode 304 can comprise a conductive element disposed at least partially around a perimeter of a print scanning surface 310. In this way, for example, when a relief object 302 is applied to the print scanning surface 310 at least a portion of the relief object 302 may contact the contact electrode 304. In the example implementation 350 of
As provided herein, a system may be devised that provides for mitigating a perceived electrical current for a relief object scanner. As an example, a perceivable current for a human may depend on the current type (e.g., alternating or direct) and/or a current frequency (e.g., in Hertz (Hz)). For example, as little as 1 milliampere (mA) of alternating current (AC) (e.g., 5 mA of direct current (DC), 12 mA of AC at 10 kHz) may be perceived by a person at 60 Hz, resulting in a perceived electrical shock. While these types of electrical shocks typically present little or no danger to a person, they may be uncomfortable to the scannee whose relief prints are being scanned.
In one aspect, a reduction in the voltage for the relief object scanner device may be implemented, for example, where an amount of reduction may be based on circumstances at a time of relief object scanning. Further, the current used to scan a relief object may be increased, for example, merely at the time the relief object contacts a scanning surface of the relief object scanner device. In one implementation, data, indicative of one or more relief object scanning variables, may be collected and processed at the time of relief object scanning. In this implementation, the data may be used to identify a desired voltage and/or current (e.g., or some other characteristic of current, such as resistance, electrical impedance, frequency, and/or amperage) for the scanning that can provide a more comfortable experience to the scannee, while also providing a desired image quality for the resulting image of the relief object.
In the exemplary system 400, the current adjusting component 402 is operably coupled with the current determination component 404. The current adjusting component 402 is configured to adjust the first current configuration, resulting in a second current configuration, based at least upon current adjustment data provided by the current determination component 404. In one implementation, the current adjusting component 402 can adjust at least one characteristic 450 of the electrical current 454 provided to the electroluminescent-based relief print scanning device 458, resulting in an adjusted current configuration.
For example, one or more current characteristics may include a voltage, amperage, frequency, resistance, and/or impedance. As one example, decreasing (or increasing) an amount of voltage provided to the relief print scanning device 558 may also decrease (or increase) a perceived electrical shock felt by a user of the relief print scanning device 558. Therefore, in this example, the current configuration comprising a particular amount of voltage provided to the relief print scanning device 558 may be identified by the current monitoring component 510, and this current characteristic 550 (e.g., voltage level) may be provided to the current determination component 404. In one implementation, one or more current characteristics 550 comprised in the current configuration (e.g., first current configuration) may be identified and provided to the current determination component 404 by the current monitoring component 510. For example, one or more of the provided current's voltage, amperage, frequency, resistance, and/or impedance may be identified for the first current configuration.
In the example implementation 500 of
In one implementation, one or more image characteristics 552 may include brightness, contrast, edge detection, object detection, luminance, luma, noise, and/or chrominance. As one example, decreasing (or increasing) an amount of voltage (e.g., and/or one or more other current characteristics) provided to the relief print scanning device 558 may also decrease (or increase) a brightness of a resulting relief print image 556 from the relief print scanning device 558. Therefore, in this example, an amount of brightness (e.g., 552) in the relief print image 556 may be identified by the image determination component 512, and this image characteristic 552 can be provided to the current determination component 404. In one implementation, one or more image characteristics 552 may be identified and provided to the current determination component 404.
With continued reference to
In one implementation, the current determination component 404 can be configured to identify the current adjustment data, where the current adjustment data comprise an indication to the current adjusting component 402 to adjust the current 554 to an adjusted current configuration (e.g., the second current configuration). That is, for example, the current monitoring component 510 (e.g., an electrical sensor or transducer) can identify the first current configuration for the current 554, comprising predetermined levels for current characteristics 550 such as voltage, resistance, electrical impedance, frequency, and/or amperage. In this example, the relief print scanner 558 can capture a first image (e.g., 556) using the current having the first current configuration. The image determination component 512 can identify one or more first image characteristics (e.g., 552), such as brightness, contrast, edge detection, object detection, luminance, chrominance, noise, and or luma, and provide them to the current determination component 404. The current determination component 404, in this example, may compare the one or more first image characteristics 552 to corresponding image threshold values 562 to determine whether the image comprises a usable image for relief print recognition (e.g., bright enough, enough contrast, appropriate edges, objects, low noise, etc.).
Further, in this example, if one or more threshold values are not met by the first image characteristic(s) 552, the current determination component can determine current variation data 560. For example, the current variation data 560 may comprise information indicative of an adjustment for one or more of the current characteristics, resulting in a second current configuration. For example, the second current configuration may comprise a change in voltage (e.g., increase) to a predetermined second voltage level; a change in resistance (e.g., decrease) to predetermined second resistance level; a change in electrical impedance (e.g., decrease) to a predetermined second impedance level; a change in frequency (e.g., increase) to a predetermined second frequency level; and/or a change in amperage (e.g., increase) to a predetermined second amperage level.
Further, in this example, the change to the second current configuration may be adjusted by the current adjusting component 402, thereby providing adjusted electrical current 554 to the relief print scanner 558 during capture of a second relief print image 556. Again, the second relief print image 556 can be analyzed, for example, by the image determination component 512 to identify one or more second image characteristics 552, which can be compared to the one or more image characteristic thresholds 562 by the current determination component 404. If the one or more second image characteristic thresholds 562 meet the respective image characteristic thresholds 562, the second relief print image 556 may be used, for example, for relief print recognition (e.g., security, identification, etc.) and/or for storage (e.g., image collection). Alternately, if the one or more image thresholds 562 are not met, the process may be iterated to create a third current configuration, a third relief print image, etc. (e.g., and a fourth, fifth, etc. until a desired image is captured).
In one implementation, the first current configuration of the electrical current 554 can comprise an available configuration in an operating range for the electro-luminescent based film disposed in the electroluminescent-based relief print scanning device 558 that provides a desired level of perceived electrical sensation to a user. That is, for example, the initial setting for the current configuration may comprise the lowest voltage (e.g., or other current characteristic 550) in an operating range for the relief print scanner 558. In this way, for example, there is a higher chance that the user may be provided a more comfortable image capture experience.
Further, in one implementation, the second current configuration can comprise a next available configuration in the operating range for the electro-luminescent based film that provides a next level of perceived electrical sensation to the user. That is, for example, if the first current configuration does not provide a useable image, the second current configuration (e.g., comprise a next higher level of voltage) may be able to provide the usable image, while still remaining at a low enough level to mitigate the electrical sensation to the user. In this way, for example, the electrical characteristics may be stepped up sequentially, at least until a usable image is obtained; thereby providing an electrical current configuration to the user that has a least perceived electrical sensation.
As provided herein, a method may be devised that provides for mitigating a perceived electrical current for a relief object scanner. As one example, a reduction in the voltage (e.g., or a change in some other current characteristic) for the relief object scanner device can be used to reduce the perceived electrical shock. For example, the reduction of voltage (e.g., or change of current) can be based on characteristics of a resulting image. Further, the current can be altered at the time the relief object contacts the scanning surface of the relief object scanner device.
If the first image characteristic does not meet the first image characteristic threshold (NO at 606), an electrical current characteristic of the first current configuration may be adjusted, at 608, resulting in a second electrical configuration. Here, at least a portion of the resulting second current configuration, comprising the adjusted electrical current 656, can be used to capture a second relief print image 652, using the electroluminescent-based relief print scanning device 650. For example, an electrical current providing component 654 may adjust an output of the electrical current 656, based on the adjusted electrical current characteristics, at 608. The adjusted electrical current 656 may be used by the electro-luminescent relief print scanner 650 to capture an image 652 of the relief print object (e.g., fingerprint). In one implementation, the process 604-608 may be iterated, at least until one or more image characteristics meet the desired threshold at 606. Having met the desired threshold at 606, and using the image, at 610, the exemplary method 600 ends at 612.
As one example, the relief print scanning device may have a baseline standard for a current configuration, comprising a baseline set of current characteristics, where the baseline set of current characteristics comprise a desired current level (e.g., providing a lowest perceived electrical sensation to a user) that may still yield a useable image (e.g., one that can be used to identify/match the resulting print with a database print). In one implementation, the current provided to the device may be set at the device's baseline standard (e.g., comprising the lowest voltage, frequency, amperage, and/or highest resistance, or impedance). In this implementation, for example, the baseline current characteristics may mitigate the perceived electrical shock to the user.
At 706 in the example implementation 700, a relief print image may be captured using the provided current (e.g., the first electrical configuration set to the baseline). As described above, an electrical current is supplied to a contact electrode, which can be contacted by the scannee (e.g., user) when touching the scanning surface of the device, for example. In this example, the provided current can be used to create an image of the relief print (e.g., as described in
At 708, a resulting image can be analyzed. As described above, the relief print device can produce an image of the relief print, where the initial image (e.g., first relief print image 456 of
At 714, the one or more image characteristics, identified at 708, can respectively be compared against an associated threshold. In one implementation, the analysis can comprise comparing the first image characteristic with a first image characteristic threshold, to determine whether the image characteristic meets the desired threshold. As one example, an image's brightness level and/or contrast level may affect the device's ability to detect the relief print, and/or compare the print against a comparison database of prints. Therefore, for example, an image brightness level threshold and/or an image contrast level threshold may be compared against the one or more image characteristics identified for the image. As an example, an image brightness for an image may comprise and average (e.g., or some other suitable statistic) brightness value for the respective pixels in the image. As another example, likewise, the image contrast for an image may comprise and average (e.g., or some other suitable statistic) contrast value for the respective contrasting pixels in the image.
In one implementation, comparing the first image characteristic with the first image characteristic threshold can comprise determining whether the first relief print image comprises data that is usable for relief print recognition. That is, for example, if the image does not comprise a desired number of relief print edges or objects (e.g., indicative of the ridges of a fingerprint), the image may not be useable for relief print recognition (e.g., comparison, storage and identification).
If the one or more image characteristics meets (e.g., or exceeds) their corresponding image characteristic threshold (YES at 714), the example implementation 700 can end, at 718, for example, and the resulting image may be utilized by the relief print object scanning device (e.g., for storage and/or identification). If the one or more image characteristics does not meet their corresponding image characteristic threshold (NO at 714), the starting current settings for the relief print object scanning device may be adjusted to a next level, at 716. In one implementation, a second electrical current configuration can be identified, if the first image characteristic does not meet the first image characteristic threshold.
In one implementation, identifying the second electrical configuration can comprise adjusting the electrical current configuration to a next available configuration in the operating range for the electro-luminescent based film that provides a next level of perceived electrical sensation to the user. In this implementation, one or more characteristics of the electrical configuration may be identified for adjustment, including: voltage, resistance, electrical impedance, electrical frequency, and/or amperage. As one example, a voltage level for the current provided to the scanning device may be increased by a desired amount (e.g., determined by empirical evidence), and used to collect a second image, where the second current configuration provides a next lowest perceived electrical sensation to the user.
Returning to 706, a second image can be collected by the relief print scanning device, using the second current configuration comprising the adjusted current (e.g., adjusted to the next level). The resulting image (e.g., second relief print image) may be analyzed, at 708, and the identified image characteristic(s) can be compared against the threshold(s). If the image is suitable (e.g., usable for relief print recognition), for example, the example implementation 700 may end at 718. However, if one or more of the thresholds are not met, the process 716-706-714 may be iterated, at least until a suitable image is identified. In this way, for example, the current provided to the scanning devices is merely incremented enough to provide a suitable image, which may result in a lower perceived electrical shock to a user of the device.
