20140354608 | DEVICES AND METHODS OF SENSING - A method is disclosed, including detecting a signal representative of an object with a piezoelectric device. A display is powered up from a sleep mode based upon the detected signal. The display can be powered up based upon a comparison of the signal to a threshold value. The threshold value can be a predetermined value or based upon a previous signal detected by the piezoelectric device or a previous signal detected by the piezoelectric device. | 12-04-2014 |
20140355387 | ULTRASONIC RECEIVER WITH COATED PIEZOELECTRIC LAYER - This disclosure provides systems, methods and apparatus related to an ultrasonic receiver for detecting ultrasonic energy received at a first surface of the ultrasonic receiver. The ultrasonic receiver includes an array of pixel circuits disposed on a substrate, each pixel circuit in the array including at least one thin film transistor (TFT) element and having a pixel input electrode electrically coupled to the pixel circuit. The ultrasonic receiver is fabricated by forming a piezoelectric layer so as to be in electrical contact with the pixel input electrodes. Forming the piezoelectric layer includes coating a solution containing a polymer onto the array of pixel circuits, crystallizing the polymer to form a crystallized polymer layer and poling the crystallized polymer layer. | 12-04-2014 |
20140359757 | USER AUTHENTICATION BIOMETRICS IN MOBILE DEVICES - An authentication process may involve presenting an image on a display device, such as an icon associated with an application, indicating an area for a user to touch. At least partial fingerprint data may be obtained during one or more finger taps or touches in the area. Based on a comparison of the partial fingerprint data and master fingerprint data of the rightful user, a control system may determine whether to invoke a function. Invoking the function may involve authorizing a commercial transaction or unlocking the display device. In some implementations, determining whether to invoke the function may be based on a level of security. | 12-04-2014 |
