20140118399 | DISTORTION CORRECTION FOR VISUAL OBJECTS IN MOTION - This disclosure provides implementations of systems, devices, components, computer products, methods, and techniques for correcting or compensating for moving visual object distortions. In one aspect, a method includes combining image data from a first frame with image data from a second frame to generate a fused image frame. Additionally or alternatively, the method can include applying a shear transformation to the image data in the first frame to generate a sheared image frame. One of, or a combination of, the fused image frame and the sheared image frame may be displayed as a pre-distorted image frame so that, when viewed on the display, the pre-distorted image frame compensates for distortion that can otherwise be perceived by a user when viewing the displayed moving visual object. | 05-01-2014 |
20140125707 | COLOR PERFORMANCE AND IMAGE QUALITY USING FIELD SEQUENTIAL COLOR (FSC) TOGETHER WITH SINGLE-MIRROR IMODS - This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for applying field-sequential color (FSC) methods to displays that include single-mirror interferometric modulators (IMODs), which may be multi-state IMODs or analog IMODs. In one aspect, grayscale levels may be provided by varying a mirror/absorber gap height between black and white states. In other implementations, grayscale levels may be obtained by varying the gap height between the black state and second-order color peaks. | 05-08-2014 |
20140159587 | DYNAMIC ADAPTIVE ILLUMINATION CONTROL FOR FIELD SEQUENTIAL COLOR MODE TRANSITIONS - This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting an operational mode of a display device from a plurality of operational modes. The operational modes may include at least one field-sequential color mode in which a display is illuminated with white light while data are written to the display. The operational mode may be selected based, at least in part, on ambient light data. The ambient light data may include ambient light intensity data, ambient light spectrum data and/or ambient light direction data. The operational mode may be selected based, at least in part, on other criteria, such as color gamut data, display application type and/or battery state data. | 06-12-2014 |
20140160137 | FIELD-SEQUENTIAL COLOR MODE TRANSITIONS - This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for selecting an operational mode of a reflective display device from a plurality of operational modes that include at least one field-sequential color mode. The operational mode may be selected based, at least in part, on ambient light data. The ambient light data may include ambient light intensity data, ambient light spectrum data and/or ambient light direction data. The operational mode may be selected based, at least in part, on other criteria, such as display application type and/or battery state data. | 06-12-2014 |
20140168040 | MOTION COMPENSATED VIDEO HALFTONING - This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for halftoning video images for presentation on an electronic display. In one aspect, input frames of video data may be received, where each input frame includes a number of input pixels, each input pixel having a respective first spatial coordinate location. For each input pixel, an output pixel is generated using a selected halftone value. The selected halftone value is substantially identical to a halftone value of a corresponding pixel in a comparison frame, where a spatial coordinate location of the “corresponding pixel” is determined based on a motion vector of an image element with which the pixel is associated. | 06-19-2014 |
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 |
20150066538 | Communication Device Resource Allocation Based On Medical Data Criticality and Resource Status - Methods and devices are disclosed for managing a resource of a communication device configured to process and communicate medical data in addition to other data. The systems and devices may implement the method, including determining whether to switch to a medical mode based on at least one signal. In response to determining to switch to the medical mode, the communication device may be switched to the medical mode. A resource status associated with a plurality of resources used by the communication device may be weighed against a medical data criticality associated with the medical data managed by the communication device. The method may include allocating a resource of the plurality of resources on a sliding priority scale. The allocating may include allocating a resource of the plurality of resources preferentially to the medical data over the other data. | 03-05-2015 |
20150234986 | Medical Air Interface - Systems, methods, and devices of the various embodiments enable classification levels to be assigned to air interfaces used to transmit medical data based on health regulatory requirements. A medical communication abstraction layer executing on a computing device (or node) may determine the requirements associated with a classification level and establish air interfaces meeting those requirements with other devices (or nodes) also having medical communication abstraction layers, thereby establishing a medical data network between the devices (or nodes) meeting the requirements for the classification level. Medical data may also be assigned classification levels, and the assigned classification level of the medical data may be used by the medical communication abstraction layers to determine the medical data networks over which the medical data may be transmitted. | 08-20-2015 |
20150241393 | Ultrasonic Authenticating Button - Embodiments of an ultrasonic button and methods for using the ultrasonic button are disclosed. In one embodiment, an ultrasonic button may include an ultrasonic transmitter configured to transmit an ultrasonic wave, a piezoelectric receiver layer configured to receive a reflected wave of the ultrasonic wave, a platen layer configured to protect the ultrasonic transmitter and the piezoelectric receiver layer, a first matching layer configured to match an acoustic impedance of the platen layer with an acoustic impedance of ridges of a finger, and an ultrasonic sensor array configured to detect the finger using the reflected wave. | 08-27-2015 |
20150242601 | TRUST BROKER AUTHENTICATION METHOD FOR MOBILE DEVICES - A mobile device may perform authentication with an authenticating entity. The mobile device may comprise a plurality of sensors and a processor. The processor may be configured to: receive an authentication request from the authenticating entity requesting authentication information; and determine if the authentication request satisfies predefined user privacy preferences. If so, the processor may be configured to: retrieve the authentication information from at least one sensor to form a trust vector in response to the authentication request and to command transmission of the trust vector to the authenticating entity for authentication. | 08-27-2015 |
20150242605 | CONTINUOUS AUTHENTICATION WITH A MOBILE DEVICE - A mobile device may perform continuous authentication with an authenticating entity. The mobile device may include a set of biometric and non-biometric sensors and a processor. The processor may be configured to receive sensor data from the set of sensors, form authentication information from the received sensor data, and continuously update the authentication information. | 08-27-2015 |
