Mode for Carrying Out the Invention

[0006] In the following detailed description of the embodiments, reference is made to the accompanying drawings. The same reference numerals in different figures may indicate the same or similar elements.

[0007] The user device may include a sensor device that executes a sensing function. The optical transmitter of the sensor device may emit light directed at an object. For example, in an object detection system, the optical transmitter transmits near-infrared light toward the object, and the near-infrared light may be reflected from the object toward the sensor device. The optical receiver of the sensor device, such as an array of sensor elements, may receive light directed at the sensor device. For example, in an object detection system, the array of sensor elements may acquire information regarding light of one or more wavelengths. The array of sensor elements may include a set of sensor elements (e.g., optical sensors, spectral sensors, and / or image sensors) that acquire information regarding light of one or more wavelengths. Thus, based on the information regarding light of one or more wavelengths, the sensor device can detect an object. and / or image sensors) that acquire information regarding light of one or more wavelengths. Thus, based on the information regarding light of one or more wavelengths, the sensor device can detect an object. Based on the information regarding light of one or more wavelengths, the sensor device can detect an object.

[0008] Similarly, using the information acquired by the optical receiver of the sensor device, the characteristics of the object can be recognized. For example, the sensor device utilizes the information regarding the wavelength of the light reflected from the object. and the characteristics of the object can be recognized. For example, the sensor device utilizes the information regarding the wavelength of the light reflected from the object. to determine the distance to an object, the size of the object, the shape of the object, the spectral signature of the object, the type of the object, the speed of the object, etc. Similarly, the sensor device can determine the identity of a person, the characteristics (e.g., height, weight, moving speed, health characteristics, etc.) of the person, etc.

[0009] Some user devices such as mobile phones, wearable devices (e.g., smartwatches or smart glasses), etc. may include multiple sensor devices to perform multiple sensing functions. For example, the user device may include a camera for imaging, a fingerprint reader providing a fingerprint identification function, etc. Similarly, the user device can be connected to an external peripheral device to provide a function, for example, connected to an external heart rate monitor to provide a health parameter monitoring function . However, if a user device includes multiple separate sensor devices, excessive cost, excessive package size, excessive power resource utilization, and / or excessive processing resource utilization may occur. Further, connecting to an external peripheral device may result in excessive cost and / or package size for providing the connection function, excessive traffic via the network connection, etc.

[0010] Some embodiments described herein may provide a user device incorporating a multi-sensing sensor device. For example, the user device may include a multi-spectral filter and a sensor device that performs sensing related to multiple functions such as the execution of one or more health monitoring functions, one or more security functions, etc. In this way, the user device can incorporate multiple separate single-function sensor devices and / or multiple external peripheral devices. ​​​​​Compared with connecting to a peripheral device, it can be accompanied by a reduction in package size, cost reduction, reduction in power resource utilization, reduction in network resource utilization, etc.

[0011] Figures 1A and 1B are diagrams of Example 100 described in this specification. As shown in Figure 1A , Example 100 may include a user device including a sensor device and a sensor window. In an embodiment , the sensor window may be opaque in the visible spectrum range and transmissive in the sensing spectrum range (for example, near-infrared spectrum range, mid-infrared spectrum range, etc.). In an implementation mode, the sensor window may be configured to be a specific color in the visible spectrum range so as to conceal the sensor device in accordance with the adjacent surface of the user device . In an embodiment, the sensor window can improve the durability of the sensor device compared to the case of providing an exposed sensor device by protecting the sensor device from the external environment .

[0012] As further shown in Figure 1A, the sensor device can transmit light for spectroscopic measurement and can receive reflected light to enable spectroscopic measurement. In an embodiment, the sensor device can determine biometric authentication based on the tissue structure of the finger (for example, based on receiving light reflected by the capillaries and / or veins of the finger to determine the vascular structure of the finger) . For example, the sensor device can transmit near-infrared light through the sensor window to enable subcutaneous biometric authentication (for example, identification of the tissue structure of a finger or other body part). In this case, based on the use of subcutaneous identification techniques (for example, sensing up to an invasion depth of more than about 0.1 micron, more than about 0.5 micron, more than about 1 micron, more than about 3 microns, more than about 5 microns, etc.), the sensor device can detect surface damage of the finger, Surface-based fingerprint identification that may be hindered by dirt on the finger, water on the finger, etc. Improve the accuracy of biometric authentication compared to techniques.

[0013] Additionally or alternatively, the sensor device can transmit near-infrared light to enable heart rate determination. For example, the sensor device can transmit near-infrared light towards the user's hand, receive the reflected light, and detect the user's pulse based on measurements of one or more wavelengths of the reflected light. Based on the heart rate determination, the sensor device can determine the liveness of an object. For example, the sensor device can distinguish between an artificial imprint of a fingerprint or tissue structure and the actual fingerprint or tissue structure of a living person to improve the security of the biometric function. In some embodiments, the sensor device can perform other determinations such as blood oxygenation determination, blood glucose determination, etc. based on measurements of one or more wavelengths of the reflected light. Additionally or alternatively, the sensor device can perform classification, quantification, etc. by spectroscopy using the measurement values of near-infrared light. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device. Based on the measurements of one or more wavelengths of the reflected light, the sensor device can perform other determinations such as blood oxygenation determination, blood glucose determination, etc. Additionally or alternatively, the sensor device can perform classification, quantification, etc. by spectroscopy using the measurement values of near-infrared light. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device. Based on the measurements of one or more wavelengths of the reflected light, the sensor device can perform other determinations such as blood oxygenation determination, blood glucose determination, etc. Additionally or alternatively, the sensor device can perform classification, quantification, etc. by spectroscopy using the measurement values of near-infrared light. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device. Additionally or alternatively, the sensor device can perform classification, quantification, etc. by spectroscopy using the measurement values of near-infrared light. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device. Thus, by using surface measurements and subsurface measurements, the sensor device improves the sensing of the user device.

[0014] As shown in FIG. 1B, the user device can provide object information based on measurements (e.g., spectroscopic measurements) by the sensor device via the user interface. For example, the sensor device can provide information for identifying a user based on a fingerprint, information for identifying a heart rate, information indicating that the fingerprint is from a human rather than an artificial imprint, information for identifying a blood oxygenation level, etc. via the user interface. In some embodiments, the user device can provide information for identifying a user based on a fingerprint, information for identifying a heart rate, information indicating that the fingerprint is from a human rather than an artificial imprint, information for identifying a blood oxygenation level, etc. via the user interface.

In some embodiments, the user device can provide information for identifying a user based on a fingerprint, information for identifying a heart rate, information indicating that the fingerprint is from a human rather than an artificial imprint, information for identifying a blood oxygenation level, etc. via the user interface. In some embodiments, the user device can perform a response operation based on sensor determination. For example, the user device can automatically unlock the user interface of the user device based on biometric authentication and liveness determination. Additionally or alternatively, the user device can, based on the user's preferences and based on the identification of the user using biometric authentication and liveness determination, automatically change the layout of the screen of the user interface and / or one or more preferences. Additionally or alternatively, the user device can identify the user, identify the location of the user, and, based on biometric authentication and one or more health metrics (e.g., heart rate determination, blood oxygenation determination, blood glucose determination, etc.), issue a warning about the health status (e.g., to an emergency response dispatch device) automatically.

[0015] Thus, by using a single sensor device to perform, for example, biometric authentication and heart rate determination, the user device can achieve a reduction in size, cost, complexity, power resource utilization, network utilization, etc., compared to a plurality

[0016] of separate single - function sensor devices. As described above, FIGS. 1A and 1B are merely provided as one or more examples. Other

[0032] FIG. 4 is a diagram of Example 400 described herein. As shown in FIG. 4, Example 400 includes a sensor device 220 incorporated in a user device 210. The user device 210 includes a sensor window 410 disposed on a substrate 420 and a sensor element array 430 of the sensor device 220. In some embodiments, the sensor window 410 may include an optical filter that performs a filtering function. For example, the sensor window 410 may provide color selectivity and direct light to a plurality of sensor elements of the sensor element array 430 associated with a plurality of wavelength channels by including alternating high refractive index material

[0033] As further shown in FIG. 4 by reference numeral 440, an input optical signal is sent towards the sensor window 410. The input optical signal may include, but is not limited to, light associated with a specific spectral region (e.g., near-infrared spectral region, mid-infrared spectral region, visible spectral region, etc.). For example, an optical transmitter (e.g., of the sensor device 220 and / or the user device 210) can direct light to the sensor element array 430 and cause the sensor element array 430 to measure the light (e.g., the optical transmitter can direct light to an object and reflect the light towards the sensor element array 430). Rather than transmitting towards the body and reflecting the light towards the sensor element array 430, the sensor may be the reflected ambient light directed towards the sensor element array 430.

[0034] As further shown by reference numeral 450 in FIG. 4, the first portion of the input optical signal having the first spectral region does not pass through the sensor window 410. For example, a dielectric filter stack including a high refractive index material layer and a low refractive index material layer of the dielectric thin film layer of the sensor window 410 can cause reflection of the first portion of the input optical signal in the first direction, absorption of the first portion of the input optical signal, etc. In some embodiments, the first portion of the input optical signal may include a first light that is reflected to make the sensor window 410 opaque and / or appear a specific color, and a second light that is absorbed.

Additionally or alternatively, by making the sensor window 410 transmissive at least in part in the visible spectral region, for example enabling visible light imaging by the sensor element array 430, the need for a separate camera in the user device 210 can be eliminated.

[0035] As further shown by reference numeral 460 in FIG. 4, the second portion of the input optical signal passes through the sensor window 410. For example, the sensor window 410 can pass the second portion of the input optical signal having the second spectral region towards the sensor element array 430 in the second direction. In this case, the second portion of the input optical signal is greater than 50% of the incident light in the near-infrared spectral region, greater than 90% of the light, greater than 9 5% of the light, greater than 99% of the light, etc., within the bandpass of the sensor window 410 towards the sensor window 410. ​​​​ It may be the threshold portion of the incident light. According to some embodiments, the sensor window 410 may be associated with a multi-component filter related to a plurality of spectral ranges. For example, based on the thickness of the sensor window 410 and / or the thickness change of its layer subset, different optical wavelengths are passed through different sensor elements of the sensor element array 430 for each part of the sensor window 410, enabling multispectral sensing. It may be associated with a multi-component filter related to a plurality of spectral ranges. For example, based on the thickness of the sensor window 410 and / or the thickness change of its layer subset, different optical wavelengths are passed through different sensor elements of the sensor element array 430 for each part of the sensor window 410, enabling multispectral sensing. It may be associated with a multi-component filter related to a plurality of spectral ranges. For example, based on the thickness of the sensor window 410 and / or the thickness change of its layer subset, different optical wavelengths are passed through different sensor elements of the sensor element array 430 for each part of the sensor window 410, enabling multispectral sensing. It may be associated with a multi-component filter related to a plurality of spectral ranges.

For example, based on the thickness of the sensor window 410 and / or the thickness change of its layer subset, different optical wavelengths are passed through different sensor elements of the sensor element array 430 for each part of the sensor window 410, enabling multispectral sensing.

[0036] As further shown by reference numeral 470 in FIG. 4, based on the second portion of the input optical signal being sent to the sensor element array 430, the sensor element array 430 can supply an output electrical signal for the sensor device 220 for use in, for example, fingerprint identification, heart rate determination, imaging, ambient light sensing, object presence detection, person identification, measurement implementation, communication simplification, etc. As further shown by reference numeral 470 in FIG. 4, based on the second portion of the input optical signal being sent to the sensor element array 430, the sensor element array 430 can supply an output electrical signal for the sensor device 220 for use in, for example, fingerprint identification, heart rate determination, imaging, ambient light sensing, object presence detection, person identification, measurement implementation, communication simplification, etc. As further shown by reference numeral 470 in FIG. 4, based on the second portion of the input optical signal being sent to the sensor element array 430, the sensor element array 430 can supply an output electrical signal for the sensor device 220 for use in, for example, fingerprint identification, heart rate determination, imaging, ambient light sensing, object presence detection, person identification, measurement implementation, communication simplification, etc. As further shown by reference numeral 470 in FIG. 4, based on the second portion of the input optical signal being sent to the sensor element array 430, the sensor element array 430 can supply an output electrical signal for the sensor device 220 for use in, for example, fingerprint identification, heart rate determination, imaging, ambient light sensing, object presence detection, person identification, measurement implementation, communication simplification, etc. According to some embodiments, other arrangements of the sensor window 410 and the sensor element array 430 may be utilized. For example, instead of passing the second portion of the input optical signal on the same line as the input optical signal, the sensor window 410 can direct the second portion of the input optical signal in a different direction towards the sensor element array 430 at a different location. According to some embodiments, other arrangements of the sensor window 410 and the sensor element array 430 may be utilized.

[0048] According to embodiments, the optical filter 500 has a transmittance exceeding about 50%, exceeding about 80%, exceeding about 90% for a specific spectral region (e.g., the sensing spectral region), exceeding about 95%, exceeding about 99%, etc., such as a threshold transmittance. It may be accompanied by an excessive rate. According to an embodiment, the optical filter 500 may be accompanied by a threshold opacity (e.g., based on reflectance, absorption, etc.). For example, the optical filter 500 has a transmittance of more than about 50%, more than about 80% for a specific spectral range (e.g., the visible spectral range), more than about 90% transmittance, more than about 95% transmittance, more than about 99% transmittance, etc. Thus, the optical filter 500 enables color selectivity of the sensor window and enables sensing by a sensor element disposed in the optical path of the sensor window.
