20080253764 | Methods and systems to stabilize an optical network against nodal gain changes - The present invention provides methods and systems to stabilize an optical network against nodal gain changes through two nested control loops for controlling node gain and node output power. The present invention includes two nested control-loops running at different update speeds including: an inner, faster, control-loop which sets the gains and losses within a node to achieve a node-gain target, and a node-gain target for the inner loop is set by an outer, slower, control loop that whose target is the node output power. Advantageously, the present invention reduces the problem of concatenated overshoot by minimizing the control-loop response to events that occur at other nodes. | 10-16-2008 |
20080267631 | Systems and methods for a multiple-input, multiple-output controller in a reconfigurable optical network - The present invention provides systems and methods to convert a reconfigurable optical node multiple-input multiple-output (MIMO) system to a single-input single-output (SISO) system suitable for a proportional-integral-differential (PID) control process. Advantageously, the present invention allows PID control to apply to a MIMO optical node by modeling the node as two SISO systems. The present invention optimizes the division of gain and loss between components in the reconfigurable optical node. This provides means to control the net gain and loss of a series of components when the component chain being controlled includes those components that have a single action affecting multiple channels and components that affect only one channel. The present invention utilizes control of a single quantity of amplifier gain minus attenuation for each channel, and the coupling together of all channels in the amplifier which makes the channels inter-dependent. | 10-30-2008 |
20090297140 | MEASURING CHROMATIC DISPERSION IN AN OPTICAL WAVELENGTH CHANNEL OF AN OPTICAL FIBER LINK - Two intensity modulated test signals are generated with precise frequency offset from a single laser source, and multiplexed into a combined test signal. The two modulated signals are demultiplexed at a receiver using a fixed periodic optical filter with complementary output ports. Group velocity dispersion/chromatic dispersion is measured over a large dynamic range, using pseudo-random intensity modulation and digital demodulation techniques. | 12-03-2009 |

20080262978 | Mail processing system including dimensional rating with true length support - A mail processing system that includes dimensional rating capability that provides true length support for carrier rates to prevent improper classification of mail pieces. The mail processing system determines a first dimension, parallel to the path of travel, and a second dimension, transverse to the path of travel, of a mail piece. The first dimension and second dimension are compared to each other to determine which is greater. The greater of the two dimensions is assigned to be the length of the mail piece, regardless of the orientation of the mail piece. The format of the mail piece is then determined based on a comparison of the assigned length and assigned width dimensions to maximum dimensions specified by a format table. Based on the determined format of the mail piece, a delivery fee is then calculated, and an indicium can be generated for the mail piece. | 10-23-2008 |
20090031903 | RECONFIGURABLE MAILING MACHINE FOR PRINTING AND OPENING MAILPIECES - A mailing machine for processing mailpiece envelopes, wherein a print station thereof is reconfigurable to process envelopes in two operating modes. The reconfigurable print station includes a displacement device having an integrated cutting mechanism to perform both printing and cutting operations. The displacement device includes a displacement surface for urging the mailpiece envelopes against a registration surface to facilitate print operations and a cutting mechanism coupled to the displacement device for cutting the sheet material in a direction substantially parallel to the processing path of the mailpiece envelope. The cutting device is adapted to be repositioned relative to the displacement surface such that, (i) in a first operating mode, the cutting device is retracted beneath or below the plane of the displacement surface, and (ii) in a second operating mode, the cutting device is extended above the plane of the displacement surface to cut the sheet material as it traverses the processing path. In the first operating mode, the print station is adapted to print delivery information/images, such as postage indicia, on a face surface of the mailpiece and, in the second operating mode, the print station is adapted to cut an edge of the mailpiece to open the envelope. The print heads may remain operational in the second operating mode to print mailpiece opening information such as the date, time, and/or location of mailpiece processing. | 02-05-2009 |
20100165066 | METHOD AND SYSTEM FOR PROVIDING EVIDENCE OF PRINTING IN EVENT OF PRINT HEAD FAILURE - Systems and methods for providing evidence of printing in metering systems even in the event of a print head failure are provided. Along with generating a primary image for an indicium that evidences payment, a secondary image for the indicium, identical to a corresponding portion of the primary image but at a lower density, with physical boundaries that are within the boundaries of the primary image, is also generated. The primary image is printed by a first nozzle array, and the secondary image is printed by a second nozzle array. Because the primary image completely overlaps the secondary image, the secondary image is undetectable if the primary image is properly printed. The secondary image provides evidence of printing of the indicium that can be used to obtain a refund for the indicium in the event that the primary image was not printed due to failure of the first nozzle array. | 07-01-2010 |
