Abstract:
Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.

Abstract:
A communication comprises a plurality of digital subscriber line (DSL) links, a first node having at least one application port configured for an elastic service and a plurality of DSL ports, and a second node having at least one application port configured for an elastic service and a plurality of DSL ports. Each of the first and second nodes is configured to interleave data received over the at least one application port across the plurality of DSL ports, each DSL port allocated a set of DSL timeslots for transport of the data received over the at least one application port. When a failure is detected on one of the DSL links, each of the first and second nodes is configured to interleave the data received over the at least one application port across the remaining DSL ports not connected to the failed DSL link without adjusting the set of DSL timeslots allocated to each of the remaining DSL ports for transport of the data from the at least one application port.
Abstract:
A semiconductor structure is fabricated by etching semiconductor material (100) to form one or more recesses having side walls. The semiconductor material on the side walls is then reacted to form an oxide (302) of the semiconductor material. This oxide may be then selectively removed from the side walls of the recess(es). This leads to a semiconductor structure having a high aspect ratio which is defined as the depth of the recess(es) divided by the width of the semiconductor material between the recess(es).

Abstract:
Methods and systems for IMEI registration are provided. In accordance with exemplary embodiments of the present invention, when an IMEI registration fails due to a network failure, the mobile station implements a back-off algorithm for future IMEI registration attempts. Specifically, the present invention provides a back-off algorithm which determines a different amount of time for the time period between each unsuccessful IMEI registration.

System and methods for High-speed Digital Subscriber Line Software Download are provided. In one embodiment, a Digital Subscriber Line (DSL) Transceiver Unit is provided. The transceiver unit comprises at least one DSL transceiver, wherein the at least one DSL transceiver implements an Embedded Operations Channel (EOC) and a data path over at least one DSL pair; a first memory for storing a software file for transfer over the DSL pair, wherein the software file comprises a header and at least one file record; and a second memory for storing a provisioning table, wherein the provisioning table establishes timeslot allocations for a plurality of channels communicated over the data path, including provisions for a software download channel for transmitting the software file from the first memory to a target unit over the data path.
Abstract:
A parallel operation keyboard (POK) which enables a user to provide multiple inputs simultaneously in managing a process control plant. A lock is provided to disable such simultaneous inputs. In an embodiment, multiple groups of keys are provided, with each group of keys being operable independently to modify the parameter value of a corresponding control loop. A network management station (NMS) and a server are designed to provide a suitable interface. In one implementation, each group of keys contains four keys respectively specifying increasing the parameter value, decreasing the parameter value, manual mode (in which the present level of the variable is controlled by the increase/decrease keys) and normal mode (in which the set point, i.e., the desired value, for the variable is controlled).
