Abstract: The semiconductor optical amplifier device includes a plurality of active units. Each active unit includes an active stripe structure of an optical amplifying medium and a current circuit configured to inject current into the corresponding active stripe structure. Each active stripe structure extends from an input end to an output end. An optical splitter device is configured to split an incoming signal light and for distributing corresponding parts of the incoming signal light into the different input ends of the active stripe structures. The optical splitter device is configured to supply each active stripe structure with the same signals.

Abstract: A method for determining a value of a local contact potential difference by noncontact atomic force microscopy. For one or more cantilever positions above a surface of a sample: i) performing two atomic force microscopy measurements, using an oscillating cantilever, ii) thereby determining two distinct voltage values of DC voltage applied between the cantilever and the sample, and iii) obtaining a value of a local contact potential difference based, at least in part, on the two distinct voltage values determined. Wherein substantially similar distinct values indicate a substantially similar value of frequency shifts of cantilever oscillation, as measured for each of said distinct values.

Abstract: The present invention includes method and apparatus for storing provisioned information within the optical switches and retrievable by every controller. The optical switches perform failure isolation according to their provisioning information. The optical switches monitor each channel for loss of signal. The provisioning information is shared autonomously between the optical switches allowing the switches to retrieve the provisioning information of the network topology from any other optical switch in the network. Fault isolation is done by the optical switch on the level of optical switch provisioning following the paradigm of “single alarm for single fault,” thus avoiding alarm floods and ambiguous alarms, thereby saving the operator time and money.

Abstract: Spring strut bearing, which has an antifriction bearing that is arranged axially between an upper carrier part and a lower carrier part and a sealing ring. The upper carrier part has two upper rims, and the lower carrier part has two lower rims. The upper rims and the lower rims engage into one another with the result that a combined labyrinth and slip-ring seal is formed.

Abstract: The present invention provides a high capacity switching system for use in a transport network, which contains a number of input/output subsystems and a central interconnection means configurably interconnecting the input/output subsystems. The subsystems have input/output line modules for receiving and transmitting data signals to and from transmission lines of the network, one or more link modules connecting the subsystems to the interconnection means, and local switching means switching data signals in time and space domain between the input/output modules and the one or more link modules within one subsystems. The link modules are adapted to aggregate data signals from different input/output line modules of the same input/output subsystems and destined to input/output line modules of another one of said input/output subsystems into signal bursts and add a payload gap to each signal burst.

Abstract: A device for treating sheet-like substrates with light is made for a suction table, which includes a circulating suction strip for transporting the sheet-like substrates, which suction strip forms a descending loop relative to its table-parallel transport level. The loop has a descending branch and, adjacent to the latter, an ascending branch. There is a gap for the passage of light between the descending branch and the ascending branch of the suction strip, which is bridged by a stationary bridging member which at least partially allows light to pass through it and whose surface is disposed at a level slightly recessed relative to the parallel transport level, so that a high degree of accuracy and trouble-free operation are ensured even at high transport speeds.
