20090204860 | Data signal handling circuitry and methods with error analysis capabilities - To help identify a noise (interference) source in an electronic device that may be causing data errors in the device, relatively low level data receiver circuitry in the device is provided with one or more error signal output leads. An error signal on such a lead includes an error indication as soon as possible after the associated low level circuitry detects a data error. The timing of such an error indication is compared to the timing of noise from various possible noise sources in the device.

20140375679 | Dual Duty Cycle OLED To Enable Dynamic Control For Reduced Motion Blur Control With Constant Brightness In Augmented Reality Experiences - A head-mounted display (HMD) device is provided with reduced motion blur by reducing row duty cycle for an organic light-emitting diode (LED) panel as a function of a detected movement of a user's head. Further, a panel duty cycle of the panel is increased in concert with the decrease in the row duty cycle to maintain a constant brightness. The technique is applicable, e.g., to scenarios in which an augmented reality image is displayed in a specific location in world coordinates. A sensor such as an accelerometer or gyroscope can be used to obtain an angular velocity of a user's head. The angular velocity indicates a number of pixels subtended in a frame period according to an angular resolution of the LED panel. The duty cycles can be set, e.g., once per frame, based on the angular velocity or the number of pixels subtended in a frame period. | 12-25-2014 |
