A method for engineering of a connection in a WDM photonic network with a plurality of flexibility sites connected by links comprises calculating a physical end-to-end route between a source node and a destination node and setting-up a communication path along this end-to-end route. An operational parameter of the communication path is continuously tested and compared with a test threshold. The path is declared established whenever the operational parameter is above the margin tolerance. The established path is continuously monitored by comparing the operational parameter with a maintenance threshold. A regenerator is switched into the path whenever the operational parameter is under the respective threshold, or another path is assigned to the respective connection. An adaptive channel power turn-on procedure provides for increasing gradually the power level of the transmitters in the path while measuring an error quantifier at the destination receiver until a preset error quantifier value is reached. As the connection ages, the power is increased so as to maintain the error quantifier at, or under the preset value. The path operation is controlled using a plurality of optical power / gain control loops, each for monitoring and controlling a group of optical devices, according to a set of loop rules.

The display driver achieves the balance between the image quality and power-cutting ratio by controlling the backlight dimming ratio to keep the image quality after backlight dimming constant. The display driver uses e.g. MSE (Mean Square Error) as an index of image quality. The reference gradation control unit controls the data decompression and backlight dimming ratios, thereby to keep the image quality after backlight dimming constant. Assuming display data decompression, and backlight dimming, the error calculating unit calculates a decrease of luminance for an input displayed image as MSE based on the decompression and dimming ratios of a preceding frame, in advance. In the case of MSE over a predetermined value, the decompression unit and light-adjustment control unit decrease the decompression and dimming ratios to below those of the preceding frame, respectively. In the case of MSE below the value, the ratios are lowered to below those of the preceding frame.

A data processing apparatus and method are provided for controlling access to memory. The data processing apparatus comprises main processing logic operable to execute a sequence of instructions in order to perform a process, and subsidiary processing logic operable to perform at least part of the process on behalf of the main processing logic. A memory is provided that is accessible by the main processing logic when performing the process, the main processing logic defining a portion of the memory to be allocated memory accessible to the subsidiary processing logic when performing part of the process on behalf of the main processing logic. Further, a memory management unit is provided that is programmable by the main processing logic and operable to control access to the allocated memory by the subsidiary processing logic. The main processing logic is arranged to program the memory management unit such that for an access request issued by the subsidiary processing logic relating to the allocated memory, the memory management unit produces a memory address and one or more associated memory attributes identifying one or more properties of the allocated memory at that memory address.

A rotor core which has relatively high rigidity, can ensure sufficient magnetic performance, and can be produced at a cheaper cost with a relatively small-scale facility. A claw-equipped core and a yoke are manufactured separately. After fitting the yoke to a fitting portion formed in the claw-equipped core, a part of the claw-equipped core in the vicinity of the fitting portion is axially pressed to plastically flow into an annular groove formed in the yoke, thereby integrally joining the claw-equipped core and the yoke to each other. Thus, a large-scaled manufacturing facility is not required, and claws of the claw-equipped core are hard to open in the radial direction even under the action of a centrifugal force during high-speed rotation. A stator core and the claws of the claw-equipped core can be positioned closer to each other, and deterioration of magnetic performance can be avoided.

A device used to ensure that a ladder is properly leveled includes an L-shaped base having one arm oriented at a right angle with respect to a second arm in one plane and at a 75° angle with respect to the second arm in a second plane. One arm includes a clip element for releasable attachment to a ladder. Bubble levels are located in each arm and are used to ensure that a ladder on which the device is mounted is level in two planes.
