Abstract: The disclosed embodiments provide a method and apparatus for optimizing power efficiency in liquid crystal displays. A microprocessor or embedded microcontroller associated with circuit control modules eliminates redundancy by allowing a single inverter to equalize the intensity of illumination for an array of multiple CCFLs. The microcontroller optimizes power management by continuously sensing the operating currents of every lamp and automatically adjusts for variations in illumination of individual lamps by parallel switching of capacitance that ensures an equal current is applied to each lamp. The microcontroller produces the appropriate control signals and executes a digital servo control algorithm to modify the currents for carrying out the luminance adjustments.

Abstract: The present invention provides an apparatus and a method for digital control of a backlight system in an LCD display. More specifically, the system utilizes a control system in embedded firmware and a mixed signal micro controller unit (MCU) to allow servo digital control of the operation of the backlight system. The MCU provides multiple input and output ports. The ports operate digital and analog signals, which connect a processor to the backlight system and allow the processor to operate the functions of the inverter and the lamps. The embedded firmware control implements digital servo functions and several algorithms used to precisely and automatically set lamp operation, control individual lamps, compensate for aging, perform diagnostics, optimize power consumption and automate manufacturing tests.

Abstract: The present invention provides for a method for configuring a laser operating system. More specifically, the system utilizes a graphical user interface (GUI) to allow an operator to interact with an embedded controller and set parameters for an optical communications transceiver. The system adjusts parameters such as laser bias and modulation currents, wavelength, qualification tests, and file management “the GUI (100) manages configurations of a transceiver operating system”. The system provides for an efficient method to design a laser transceiver and to perform and manage qualification tests. The embedded controller may contain a real time operating system that controls multiple functions in the transceiver and an optical channel. The GUI interacts with an operating system to download embedded firmware into an embedded micro controller unit “MCU”. Downloading of firmware allows for multiple special programs from different sources to be integrated.

Abstract: Methods for controlling lasers or other light emitting devices to compensate for performance degradations due to temperature changes and aging without disrupting the transmission of information are presented. Disclosed embodiments describe various methods of applying mathematical models and digital signal processing algorithms to continuously calculate and execute precise output power adjustments. A synthesized test signal is injected into the normal data stream is applied to the laser system. The magnitude of the test signal is sufficiently small that it is buried in system noise and will not alter the noise margin of the signal or the transmitted data. Micro-detection, recovery and digital signal processing of the embedded test signal produces precisely monitored output power and modulation amplitude measurements used to accurately adjust performance characteristics regardless of temperature or age.

Abstract: A system contains a laser output measurement circuit used in a laser control system (210). The circuits contain a photodiode sensor (109), sample and hold amplifier (202), IC with synchronizer and delay circuits (206), and an analog to digital converter (204). The circuits measure the laser light output (107) while the laser Module (106) transmits signals. The measurement circuit tracks and stores the laser light output (107) signal using a Photodiode Sensor (109) and with a Sample/hold (202). The methods calculate the value of the laser light output (107) from mathematical relationships, which correlate the light output (107) of the laser Module (106) to the current value of the drive signal (100). Some of the distinguishing features in the present invention are 1) feedback information from the photodiode is obtained in a synchronous manner as a snapshot of the laser performance, and 2) the measurements are precise and calibrated, and 3) no disruption of the signal transmission occurs.

Abstract: A controller (320) for controlling various operational parameters of the Laser Module (303). The modulation drive signal (300) causes the circuits in the driver (301) to send a signal to the output (302) so that the laser can send an optical power output (304) proportional to the drive signal (300). The control methods in Laser Controller IC (320) consist of control algorithms embedded in firmware. The Laser Controller IC (320) includes support circuits for control of a laser. Some of the distinguishing features in the present invention are 1) feedback information from the sensors is obtained in a synchronous manner as a snapshot of the laser performance, and 2) algorithms handle the entire set of controls in firmware. The algorithm feature allows for advanced servo controls, which precisely stabilize the laser, can accommodate adaptive controls, and can be leveraged from one laser transmitter design to another.
