20080262903 | SYSTEM AND METHOD TO DETERMINE THE PRICES AND ORDER QUANTITIES THAT MAXIMIZE A RETAILER'S TOTAL PROFIT - The present invention provides a system and method for determining the prices and order quantities that maximize a retailer's expected profit by using a multi-dimensional distribution of the highest prices that customers are willing to pay. This is novel, as well in the literature as in the patent database. Brand switching is dealt with, taking into account that consumers who come into the store with a-priori preferences for products build a-posteriori preferences at the point of purchase based on actual retail prices and availabilities in the store. | 10-23-2008 |

20110112998 | METHODS AND SYSTEMS FOR VARIABLE GROUP SELECTION AND TEMPORAL CAUSAL MODELING - A “variable group selection” system and method in which constructs are based upon a training data set, a regression modeling module that takes into account information on groups of related predictor variables given as input and outputs a regression model with selected variable groups. Optionally, the method can be employed as a component in methods of temporal causal modeling, which are applied on a time series training data set, and output a model of causal relationships between the multiple times series in the data. | 05-12-2011 |

20110074436 | IDENTIFICATION OF FALSE POSITIVES IN HIGH IMPEDANCE FAULT DETECTION - A method, system and computer program product are disclosed for identifying false positive indications of high impedance faults in an AC electric power transmission and distribution network. In one embodiment, the method comprises using a procedure to monitor a phase conductor of the network for faults, said procedure generating a fault signal indicating a specified fault in the conductor. In this embodiment, the voltage and current waveform of the electric power conducted through the conductor are monitored. When a phase shift in said waveform is detected over a defined period of time, and said detected phase shift meets one or more given criteria, a correction signal is generated indicating that said fault signal is a false indication of the specified fault. The given criteria may include, for example, that the phase shift is more than a threshold value for a specified period of time. | 03-31-2011 |

20080249723 | INTELLIGENT, SELF-PROPELLED AUTOMATIC GRID CRAWLER HIGH IMPEDANCE FAULT DETECTOR AND HIGH IMPEDANCE FAULT DETECTING SYSTEM - A self-propelled, automated, autonomic grid crawler which, when attached to a wire, moves along the wire to sense conditions of the wire. The grid crawler includes a central processing unit (CPU), working memory, such as random access memory (RAM), persistent money, such as read only memory (ROM) and hard drive (HD), sensor electronics, a wireless interface, a location device, such as a global positioning satellite (GPS) receiver, motive power system, and a battery. The sensor electronics serves to sense various types of faults. The CPU analyzes the data from the sensor electronics using pre-analysis and pre-qualification algorithms, which are stored in the HD. Depending on the results of the analysis, the CPU transmits information to the central station, either directly or indirectly via mounted docking devices, that potentially indicates a fault including the location of the fault as determined by the GPS receiver. The pre-processing and pre-qualifying of the data at the autonomic grid crawler limits the amount of data that needs to be transmitted to the central station, thereby saving battery power. | 10-09-2008 |
20090204347 | METHOD FOR DETECTING HIGH IMPEDANCE FAULTS BY ANALYZING A LOCAL DEVIATION FROM A REGULARIZATION - A method for detecting high impedance faults, including: receiving an input waveform from a circuit; computing a root mean square of the input waveform; fitting a regression line to the root mean squares; computing a deviation between the regression line and the root mean squares; determining whether the deviations are above a threshold; and outputting a value indicating that a fault has occurred in the circuit when the deviation is above the threshold and outputting a value indicating that a fault did not occur in the circuit when the deviation is below the threshold. | 08-13-2009 |

Ossining NY US - Methods, apparatus, and articles of manufacture are disclosed. These perform the following: accessing records of previous usage within a billing period of service units for customers, wherein the service units are discrete sizes of services for resource types, wherein each usage of an individual one of the service units has start and stop events, and wherein each resource type has a price fixed as of a date of the previous usage; dividing the billing period into time periods determined using the start and stop events for the usage of all of the service units; using the accessed records and the time periods and based on one or more criteria, assigning resource types to the previous usage in the time periods of the service units by the customers; and determining total charge for a selected customer based on the assignments of the resource types and corresponding prices for the selected customer. | 01-17-2013 |
