Abstract: A terminal provided in the present disclosure, acquires values of one or more monitoring parameters. The terminal sets, according to the monitoring parameter, a blue light output value of a to-be-adjusted pixel displayed on a screen of the terminal when a value of at least one of the monitoring parameters meets a preset rule corresponding to the monitoring parameter, where the blue light output value is less than an original blue light output value of the to-be-adjusted pixel. The screen of the terminal displays the to-be-adjusted pixel according to the blue light output value such that the terminal can set, according to the monitoring parameter, the blue light output value of the to-be-adjusted pixel displayed on the screen of the terminal, and therefore the blue light can be adjusted intelligently, and an objective of vision protection without affecting user experience is achieved.

Abstract: A method of determining whether a biometric object is part of a live individual is described. In one such method, image information is acquired from the biometric object by using a sensor, such as an ultrasonic sensor. The image information may be analyzed in at least two analysis stages. One of the analysis stages may be a temporal analysis stage that analyzes changes in the image information obtained during a time period throughout which the biometric object was continuously available to the sensor. For example, a dead/alive stage may analyze differences between image information taken at two different times in order to identify changes from one time to the next. Other stages may focus on aspects of a particular image information set, rather than seeking to assess changes over time. These other stages seek to determine whether an image information set exhibits characteristics similar to those of a live biometric object.

Abstract: Some methods may involve determining whether an object is positioned on or near a portion of a fingerprint sensor system. If an object is positioned on or near the portion of the fingerprint sensor system, an acoustic impedance of at least a portion of the object may be determined. Based at least in part on the acoustic impedance, it may be determined whether the object is a finger.

Abstract: A fingerprint sensing apparatus includes a fingerprint sensor system and a control system capable of receiving fingerprint sensor data from the fingerprint sensor system. The control system may determine, according to the fingerprint sensor data, whether an object is positioned proximate a portion of the fingerprint sensor system.

The control system may determine whether the fingerprint sensor data includes fingerprint image information of at least an image quality threshold.

Abstract: Systems and methods for multi-spectral ultrasonic imaging are disclosed. In one embodiment, a finger is scanned at a plurality of ultrasonic scan frequencies. Each scan frequency provides an image information set describing a plurality of pixels of the finger including a signal-strength indicating an amount of energy reflected from a surface of a platen on which a finger is provided. For each of the pixels, the pixel output value corresponding to each of the scan frequencies is combined to produce a combined pixel out put value for each pixel. Systems and methods for improving the data capture of multi-spectral ultrasonic imaging are also disclosed.

Abstract: Disclosed are a substrate with a microstructure and a method for producing the same. In this method microparticles of a random allocation by means of a natural self-assembly mechanism are used to coat on a master mold. Firstly, hollow micro glass particles within a specific size range are mixed with a UV-curable adhesive to become a mixed solution. Afterwards, the master mold is dip-coated in the mixed solution and the microparticles coated on the master mold are self-assembled. To fix the microparticles on the master mold to form a sphere array microstructure with a three dimensional random allocation, a UV light source is used to radiate the master mold for curing. Afterwards, an inverse mold with the corresponding microstructure is fabricated by electroforming or polydimethylsiloxane (PDMS) casting the master mold. Thus, the inverse mold can be applied to the fabrication of a substrate with the corresponding microstructure.
