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: 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.

Abstract: The invention presents a method that calibrates the laser optical power (202) in a continuous manner without disrupting the flow of information in the optical communications link. The method utilizes knowledge of the measured value of the laser optical power (202) and makes necessary adjustments to optimize the values of the Extinction Ratio, Bit Error Rate and to compensate for aging. The method utilizes knowledge of the temperature from a sensor (114) and mathematical models, which contain parameters which are updated for a specific laser configuration.
