    摘要: In a scanning backlight for an LCD display, several backlights (101, 102, 103, 10n) provide a precisely positioned dimming pulse corresponding to a transition point of the LCD screen. The dimming pulse must be variable with video synchronization frequency and dimming duty cycle, which is a performance intensive calculation. One microcontroller performing this operation is limited in scope. By using several ballast controllers (141, 142, 143, 14n), the solution is scalable, in that it is flexible if the number of backlights (101, 102, 103, 10n) changes. Additionally, by using several controllers (141, 142, 143, 14n), added functions can be performed by the ballast controllers (141, 142, 143, 14n).

    摘要: Systems and methods are disclosed that facilitate switching a lamp ballast between DALI and analog control states as a function of control state information stored prior to the ballast being powered of and control information received by an interface circuit for the ballast circuit. A depolarization circuit is coupled to the interface circuit and ensures consistent polarity across a rectifier circuit regardless of the polarity of two control wires coupled to a miswiring protection circuit in the interface circuit. In this manner, a single interface circuit provides dual 0-10V analog and DALI control for dimming a lighting device regardless of whether a wall-mounted controller coupled to the interface circuit is an analog or a DALI type controller, thereby mitigating a need to switch out a ballast circuit coupled to the lighting device when changing between DALI and analog type controllers.

    摘要: A steam turbine rotor has at least a first stage and a last stage. The rotor is optimised for operation in a wet steam environment at steam temperatures of less than 300° C. by being made more resistant to stress corrosion cracking (SCC). The yield strength of the rotor varies along its axial length such that the yield strength of the rotor in the region of the last turbine stage is more than the yield strength of the rotor in the region of at least one earlier turbine stage.

    摘要: In order to obtain a novel binding protein against a chosen target, DNA molecules, each encoding a protein comprising one of a family of similar potential binding domains and a structural signal calling for the display of the protein on the outer surface of a chosen bacterial cell, bacterial spore or phage (genetic package) are introduced into a genetic package. The protein is expressed and the potential binding domain is displayed on the outer surface of the package. The cells or viruses bearing the binding domains which recognize the target molecule are isolated and amplified. The successful binding domains are then characterized. One or more of these successful binding domains is used as a model for the design of a new family of potential binding domains, and the process is repeated until a novel binding domain having a desired affinity for the target molecule is obtained. In one embodiment, the first family of potential binding domains is related to bovine pancreatic trypsin inhibitor, the genetic package is M13 phage, and the protein includes the outer surface transport signal of the M13 gene III protein.
