20090060496 | Method and system for enabling diagnosing of faults in a passive optical network - In a passive optical network (PON), multiple optical network terminals (ONTS) transmit data to an optical line terminal (OLT) using a common optical wavelength and fiber optical media. Various components of the PON, including the OLT and ONT(s), can malfunction.

Thus, fault conditions may occur and not be diagnosed due to lost or overwritten information. Therefore, a distributed approach based on information related to ranging of ONTs within the PON is employed in an example embodiment of the invention. This distributed approach can improve monitoring and diagnosis of fault conditions that may lead to instability of the PON. | 03-05-2009 |

20090187436 | Online Marketplace for Moving and Relocation Services - Methods and systems for operating an online marketplace for the sale of goods and services associated with self-help moving and relocating are described. A customer enters an online marketplace where vendors offer services and goods relating to moving and relocating, specifically in the “do-it-yourself” moving field. The venue for the online marketplace is an Internet web site or a site on a computer network and is operated by a host that determines which vendors will be listed on the site. Once in the marketplace, the customer can view informational content on numerous vendors providing services relating to moving and relocating. Based on the estimates provided by the marketplace as well as reviews, ratings, customer feedback, and background information on the vendors, the customer selects a vendor and “prepays for” the vendor's services on the marketplace. The customer is then provided a confirmation code. The code is given to the vendor upon completion of service or delivery of the good to the customer's satisfaction. The vendor accesses the online marketplace and enters the confirmation code to activate a payment for the service or good. | 07-23-2009 |

20100320956 | Energy Saving System and Method for Devices with Rotating or Reciprocating Masses - A system and method are provided for reducing the energy consumed by a pump jack electric motor by reducing the supply voltage to the motor when the motor would be generating energy in open loop mode. By substantially eliminating the energy generation mode, the braking action of the utility grid in limiting the acceleration of the motor and system that would otherwise occur is substantially removed. The motor and system will speed up, allowing the natural kinetic energy of the cyclic motion to perform part of the pumping action. A closed loop controller in electrical connection with the motor computes the necessary information from the observed phase angle between the voltage and current supplied to the motor. By reducing the supply voltage to the motor, the observed phase angle may be reduced to a target phase angle value. By allowing some current flow, primarily of a reactive nature, an observable feedback parameter may be used in the closed loop control system as an indication of the load condition, to which the closed loop motor controller may react, supplying power when needed, such as in the energy consumption mode. The electric motor may be effectively turned off, but without completely cutting the power to the motor. During both the energy consumption mode and the period that open loop energy generation would be occurring, the closed loop motor controller may reduce the observed phase angle to a target phase angle by reducing the supply voltage. Any further reduction in the observed phase angle below the target phase angle may be interpreted as an increase in motor load, to which the motor controller may respond by increasing the supply voltage to the motor until the target phase angle is once again reached. | 12-23-2010 |
20110080130 | METHOD TO SAVE ENERGY FOR DEVICES WITH ROTATING OR RECIPROCATING MASSES - A system and method are disclosed for turning off the voltage to a pump jack electric motor during predetermined periods of time to save energy. In the method, the motor's response to closed-loop control may be evaluated over several pump strokes. The periods of the pump stroke when it is feasible to turn off the motor may be identified. The consistency of the measurements over several strokes may be evaluated. The motor may be turned off during predetermined periods on subsequent pump strokes when each pump stroke shows sufficiently similar behavior to that predicted during the closed-loop control process. The system may return to the closed-loop control process after a predetermined period of time to adjust to any changes in the system. | 04-07-2011 |
20120213645 | Energy Saving System and Method for Devices with Rotating or Reciprocating Masses - A system and method are provided for reducing the energy consumed by a pump jack electric motor by reducing the supply voltage to the motor when the motor would be generating energy in open loop mode.

20140176040 | SYSTEM AND METHOD FOR SAVING ENERGY WHEN DRIVING MASSES HAVING PERIODIC LOAD VARIATIONS - A system and method are described for conserving energy by decoupling a supply voltage to an electric motor operating under periodic load variations. A time segment value corresponding to a duration of periodic load variations is obtained and the supply voltage is adjusted to maintain an observed phase angle for a supply voltage and current at a value corresponding to a target phase angle. At least one off-time period is identified during the time segment value that corresponds to when the adjusted supply voltage is applied to the motor. During a remainder of the time segment value, at least one turn-on time period is provided when the supply voltage is coupled to the motor. The system may enter to a closed-loop control process after a predetermined period of time to adjust to any changes in the periodic load variations. | 06-26-2014 |
20140294602 | ENERGY SAVING SYSTEM AND METHOD FOR DEVICES WITH ROTATING OR RECIPROCATING MASSES - A system and method are provided for reducing the energy consumed by a pump jack electric motor by reducing the supply voltage to the motor when the motor would be generating energy in open loop mode. By substantially eliminating the energy generation mode, the braking action of the utility grid in limiting the acceleration of the motor and system that would otherwise occur is substantially removed. The motor and system will speed up, allowing the natural kinetic energy of the cyclic motion to perform part of the pumping action. In particular, when the energy consumption for the electric motor connected with the device having a rotating or reciprocating mass goes to zero, the line voltage to the motor is switched off, causing the frequency of the voltage across the motor terminals to increase. When the period of the voltage across the motor terminals returns to substantially the same as the period of the line voltage, the line voltage is switched on or reapplied to the motor. | 10-02-2014 |
