20080316588 | APPARATUS AND METHOD FOR GENERATING AN RF SIGNAL - An apparatus for generating an RF signal is provided includes a driver configured to generate a timing control for two optical signals. The apparatus further includes at least one optical pulse source configured to generate the two optical signals based on the timing control. In addition, the apparatus includes a photodetector configured to receive the two optical signals as input and further configured to generate an RF signal based on the two optical signals. A method for generating an RF signal is also provided. | 12-25-2008 |
20100289594 | MODULATOR DRIVER CIRCUIT HAVING CHIRPED COMPONENTS - Embodiments of the present invention provide arrays of electrical circuits having one or more chirped elements or components for providing output signals to corresponding arrays of electro-optic devices. Certain embodiments of the present invention include a plurality of modulator driver circuits, each of the plurality of driver circuits configured to be substantially identical to each other and provide a corresponding one of a plurality of modulator drive signals to a respective one of a plurality of electro-optic modulators, each of the plurality of modulator driver circuits being chirped to provide a desired output to the corresponding electro-optic modulator for enhanced operation. Each of the plurality of modulator driver circuits comprises a plurality of electrical components, at least one of the electrical components being chirped such that a design or operating parameter of the electrical component differs from an electrical component having a similar function in at least one of the remaining modulator driver circuits of the plurality of driver circuit. In certain embodiments, each of the plurality of modulator driver circuits is provided on a common substrate. | 11-18-2010 |
20110076019 | SYSTEM FOR GENERATING OPTICAL RZ SIGNALS BASED ON ELECTRICAL RZ SIGNALS - Consistent with the present disclosure, polarized optical signals having the same wavelength are modulated in response to ERZ drive signals, to thereby yield corresponding RZ optical signals. Each of the polarized RZ optical signals includes a plurality of RZ transitions wherein the power of the optical signal returns to zero or a minimal power between bits or symbols. The phase or timing of the ERZ drive signals, however, is controlled, so that the RZ transitions in one polarized optical signal remain interleaved with the RZ transitions of the other polarized optical signal. Alternatively, the RZ transitions of the two polarized optical signals may be controlled so that the two are temporally aligned with one another. Thus, the timing of the RZ transitions of one polarized optical signal relative to the other polarized optical signal may be adjusted to optimize system performance. | 03-31-2011 |
20110150481 | ELECTRICAL RETURN-TO-ZERO (ERZ) DRIVER CIRCUIT - Consistent with the present disclosure, clock-and-data recovery (CDR) circuitry and driver circuitry are provided on a chip that is separate from the driver circuitry, thereby reducing the amount of power consumed by the driver circuitry and simplifying system design. In one example, timing of the ERZ signals is controlled by a feedback loop that adjusts the phase of a data carrying signal relative to a clock signal, such that the phase has a desired value. Timing of the ERZ signals may thus be adjusted to minimize errors. | 06-23-2011 |

20110167349 | ANNOTATION FEATURE FOR PRODUCTION PARTS IN A MEDIA PRODUCTION SYSTEM - A system providing a user interface to annotate different items in a media production system such as in a digital non-linear post production system. Parts of the production, such as clips, frames and layers, that have an associated annotation are provided with a visual annotation marker. The annotation marker can use shape, color or animation to convey source, urgency, status or other information. Annotations can be text, freehand drawing, audio, or other. Annotations can be automatically generated. Annotations can be compiled into records, searched and transferred. A state of an application program can be stored and transferred to a remote system. The remote system attempts to recreate the original state of the application program. If the remote system is unable to do so, an image of the state of the application program is obtained, instead. Assignment of control to various functions of an application program is achieved by associating a function (i.e., modifying a parameter) with a user control at a remote location. | 07-07-2011 |
20120159342 | ASSIGNMENT OF A LOCAL FUNCTION TO A REMOTE USER CONTROL IN A MEDIA PRODUCTION SYSTEM - A state of an application program can be stored and transferred to a remote system. The remote system attempts to recreate the original state of the application program. If the remote system is unable to do so, an image of the state of the application program is obtained, instead. Assignment of control to various functions of an application program is achieved by associating a function (i.e., modifying a parameter) with a user control at a remote location. | 06-21-2012 |
20120294589 | DIGITAL VIDEO EDITING SYSTEM INCLUDING MULTIPLE VIEWING WINDOWS OF A SAME IMAGE - The system provides different ways for users to select an object and an action to be applied to the object in computer applications such as image processing or digital post-production. The user can select an object first and then an action, or vice versa. The user can also use gestural input to designate both an object and action virtually simultaneously. Multiple view, or windows, of an image can be independently sized, zoomed, panned, etc. Any effects performed on the image appear in all of the windows since each window shows (potentially) different portions of the same image content. A navigation window helps a user move within a large image or diagram that does not fit entirely on a single display screen. The navigation window includes an inner box that shows, in miniature, the principal objects in the screen display. | 11-22-2012 |
