20090160740 | ELECTROLUMINESCENT DISPLAY COMPENSATED ANALOG TRANSISTOR DRIVE SIGNAL - Apparatus for providing an analog drive transistor control signal to the gate electrode of a drive transistor in a drive circuit that applies current to an EL device, the drive circuit including a first supply electrode of the drive transistor and the EL device connected to a second supply electrode of the drive transistor, comprising a measuring circuit for measuring the current passing through the supply electrodes at different times to provide an aging signal representing variations in the characteristics of the drive transistor and EL device caused by operation of the drive transistor and EL device over time; a compensator for changing a linear code value in response to the aging signal to compensate for the variations in the characteristics of the drive transistor and EL device; and a linear source driver for producing the analog drive transistor control signal in response to the changed linear code value. | 06-25-2009 |
20090167644 | RESETTING DRIVE TRANSISTORS IN ELECTRONIC DISPLAYS - A method for resetting drive transistors associated with subpixels in an electroluminescent display, comprising providing an electroluminescent display having a plurality of subpixels, each subpixel including an electroluminescent device and a drive circuit having a drive transistor for providing current through its associated electroluminescent device; providing a separate aging signal for each subpixel during operation of the electroluminescent display after a predetermined operating time period by responding as a function of the current passing through each of the subpixels or as a function of a voltage associated with each drive circuit; comparing each of the separate aging signals with a corresponding threshold level to produce a separate staleness signal for each subpixel representing whether or not the associated drive transistor should be reset; and resetting the associated drive transistors in response to staleness signals that indicate such drive transistors should be reset. | 07-02-2009 |
20100123699 | ELECTROLUMINESCENT DISPLAY INITIAL-NONUNIFORMITY-COMPENSATED DRIVE SIGNAL - An electroluminescent (EL) panel with 2T1C subpixels is compensated for initial nonuniformity (“mura”). The current of each subpixel is measured at a selected time to provide a status signal representing the characteristics of the subpixel. A compensator receives a linear code value and changes it according to the status signals. A linear source driver drives the panel with the changed code values. | 05-20-2010 |

20150149355 | SYSTEM AND METHOD FOR STAGING VOUCHER TRANSFERS - Various embodiments concern methods of operating a server to facilitate transfer of a voucher to a receiver. Such methods include receiving a request at a server from a sender, the request indicating an identity of a receiver and a value designation, and receiving a selection of one or more vendors at the server. The methods further include sending a reference number to the sender from the server and receiving the reference number at the server from the receiver. The reference number is communicated from the sender to the receiver independently of the server. The methods further include authorizing release of a voucher to the receiver based on the reception of the reference number at the server and authentication of the identity of the receiver, the voucher redeemable only for goods and services with the selected one or more vendors. | 05-28-2015 |

20140161169 | JOINT PAPR REDUCTION AND RATE ADAPTIVE ULTRASONIC OFDM PHYSICAL LAYER FOR HIGH DATA RATE THROUGH-METAL COMMUNICATIONS - A link adaptive orthogonal frequency-division multiplexed (OFDM) ultrasonic physical layer is provided that is capable of high data rate communication through metallic structures. The use of an adaptive OFDM subcarrier-based modulation technique mitigates the effects of severe frequency selective fading of the through-metal communication link and improves spectral efficiency by exploiting the slow-varying nature of the channel. To address the potential ill effects of peak-to-average power ratio (PAPR) and to make more efficient use of the power amplifiers in the system, the invention modifies and implements a symbol rotation and inversion-based PAPR reduction algorithm in the adaptive OFDM framework. This joint adaptive physical layer is capable of increasing data rates by roughly 220% in comparison to conventional narrowband techniques at average transmit powers of roughly 7 mW while constrained to a desired BER. | 06-12-2014 |
