20080320485 | Logic for Synchronizing Multiple Tasks at Multiple Locations in an Instruction Stream - Logic (also called “synchronizing logic”) in a co-processor (that provides an interface to memory) receives a signal (called a “declaration”) from each of a number of tasks, based on an initial determination of one or more paths (also called “code paths”) in an instruction stream (e.g. originating from a high-level software program or from low-level microcode) that a task is likely to follow. Once a task (also called “disabled” task) declares its lack of a future need to access a shared data, the synchronizing logic allows that shared data to be accessed by other tasks (also called “needy” tasks) that have indicated their need to access the same. Moreover, the synchronizing logic also allows the shared data to be accessed by the other needy tasks on completion of access of the shared data by a current task (assuming the current task was also a needy task). | 12-25-2008 |
20090282408 | SYSTEMS AND METHODS FOR MULTI-TASKING, RESOURCE SHARING, AND EXECUTION OF COMPUTER INSTRUCTIONS - In a multi-tasking pipelined processor, consecutive instructions are executed by different tasks, eliminating the need to purge an instruction execution pipeline of subsequent instructions when a previous instruction cannot be completed. The tasks do not share registers which store task-specific values, thus eliminating the need to save or load registers when a new task is scheduled for execution. If an instruction accesses an unavailable resource, the instruction becomes suspended, allowing other tasks' instructions to be executed instead until the resource becomes available. Task scheduling is performed by hardware; no operating system is needed. Simple techniques are provided to synchronize shared resource access between different tasks. | 11-12-2009 |

20090296302 | SURGE PROTECTION SYSTEMS AND METHODS FOR OUTSIDE PLANT ETHERNET - The present disclosure generally pertains to surge protection systems that protect outside plant equipment from high-energy surges. In one exemplary embodiment, a protection system is used for protecting Ethernet equipment that is coupled to an outside Ethernet cable. The protection system provides protection and remains capable of coupling signal energy between an Ethernet cable and Ethernet equipment without significantly degrading Ethernet performance. However, the protection system, while allowing the desirable Ethernet signals to pass between the cable and the equipment, prevents the electrical voltages and currents of high-energy surges, such as surges from lightning or AC power faults, from damaging the Ethernet equipment. | 12-03-2009 |
20100322363 | ADAPTIVE INTERFERENCE CANCELING SYSTEM AND MEHOD - A communication system adaptively cancels noise and/or interference from signals communicated through a communication channel, such as signals communicated by a telecommunication network. The system, based on a common mode signal of a received signal, generates an estimate of noise or interference within a differential mode signal of the received signal. The system then subtracts the estimate from the differential mode signal in an effort to remove noise from the differential mode signal thereby providing a differential mode signal that is substantially free of the estimated noise or interference. | 12-23-2010 |

20120236856 | SYSTEMS AND METHODS FOR COMMUNICATIONS ACROSS DROP CONNECTIONS - A controller at a distribution point (DP) of a communication system is coupled to a plurality of customer premises (CP) transceivers via drop connections in a point-to-multipoint architecture. Each drop connection is coupled to at least one switch that operates under the control of the controller for selectively isolating the drop connection from the controller, as well as the CP transceivers of other drop connections. In this regard, by controlling the states of the switches, the DP controller can control to which of the CP transceivers it is communicatively connected, and during operation the DP controller controls the switches such that it is communicatively connected only to the CP transceivers for which communication is desired or needed during a particular time interval. | 09-20-2012 |
20120250840 | SYSTEMS AND METHODS FOR POWERING NETWORK ACCESS DEVICES FROM CUSTOMER PREMISES EQUIPMENT - A communication system has a network access device (NAD) that is designed to deliver Plain Old Telephone Service (POTS) along with high-speed data to Customer Premises Equipment (CPE). The NAD is backpowered by the CPE across a subscriber line. When backpower is provided from the CPE, circuitry (referred to as a “POTS signaling element”) within the network access device converts POTS control signaling to digital data for transmission to the CPE. The band vacated by the POTS control signaling is used for the power signal on the subscriber line. In the absence of backpower, components of the network access device are bypassed, thereby providing POTS in the event of a power failure. The NAD receives advance warning of the backpowering so that it can disable the bypassing in order to prevent the power signal from leaking through the NAD to the network. | 10-04-2012 |
20130187457 | DEVICE AND METHOD FOR POWERING ETHERNET MIDSPAN DEVICE AND ENDSPAN DEVICE - A midspan device for providing power and data from a one-pair power sourcing equipment to a two-pair powered device is described. The midspan device is connected to the one-pair power sourcing equipment and takes a portion of the power from the power sourcing equipment to power a converter. The converter converts one-pair data into a two-pair data and forwards the converted data to the two pairs of the powered device. Another portion of the power from the power sourcing equipment is on a DC path and coupled through center tap transformers to provide power to the powered device. | 07-25-2013 |

The OSA comprises a laser diode configured to transmit optical signals across the optical fiber, and the OSA further comprises an avalanche photodiode (APD) configured to receive optical return signals from the optical fiber. The system further comprises a crosstalk canceller configured to estimate an amount of electrical crosstalk affecting measurements of the return signals in order to cancel such crosstalk from measurements of subsequent optical signals received by the APD. | 08-08-2013 |
20130202287 | CORRELATION SYSTEMS AND METHODS WITH ERROR COMPENSATION - A correlation system, such as a correlation optical time domain reflectometer (OTDR) system, transmits a correlation sequence, such as an M-sequence, and measures the returns of the correlation sequence over time. The system correlates the transmitted sequence with the returns to provide correlation measurement values that respectively correspond to different distances from the point of transmission. A correlation error compensation element estimates a correlation error floor based on at least one correlation measurement value corresponding to a point along the fiber beyond a finite impulse response (FIR) length from the transmitter. The correlation error compensation element adjusts each correlation measurement value estimate in order to cancel the contribution of the correlation error floor from the measurements to provide compensated measurement values that are substantially free of the effects of the correlation error floor. | 08-08-2013 |
20130251363 | SYSTEMS AND METHODS FOR REDUCING THERMAL TAILS ON OPTICAL TIME DOMAIN REFLECTOMETER (OTDR) MEASUREMENTS - An optical communication system has a power dissipating element that is thermally coupled to an optical transmitter. The currents supplied to the transmitter and the power dissipating element are controlled such that the sum of such currents is constant. Accordingly, temperature fluctuations in the transmitter due to patterns in the transmitted data are prevented or at least reduced, thereby reducing thermal tails on measurements. In one exemplary embodiment, a light source is used as the power dissipating element, and the output of such light source is beneficially used to probe another optical fiber or to enhance the OTDR performance or analysis. | 09-26-2013 |
