Abstract: A sensor detects partial discharges (PDs) in an electrical power system and generates a corresponding analog electrical signal. A data acquisition component receives the signal from the sensor and converts it to digitized zero span data for a series of uniformly spaced frequencies in a frequency spectrum of interest. A digital signal processing component receives the digitized zero span data, analyzes such data, and generates a corresponding phase resolved spectrum signal in three dimensional format including dimensions of amplitude, phase and frequency for each of the uniformly spaced frequencies. A display component receives the analyzed data stream from the processing component and actuates one or more displays from which characteristics of the PD can be identified, such as different types of PDs from different sources, and information on the location of a PD relative to the sensor.

Abstract: The accuracy of photovoltaic simulation modeling is predicated upon the selection of a type of solar resource data appropriate to the form of simulation desired. Photovoltaic power simulation requires irradiance data. Photovoltaic energy simulation requires normalized irradiation data. Normalized irradiation is not always available, such as in photovoltaic plant installations where only point measurements of irradiance are sporadically collected or even entirely absent. Normalized irradiation can be estimated through several methodologies, including assuming that normalized irradiation simply equals irradiance, directly estimating normalized irradiation, applying linear interpolation to irradiance, applying linear interpolation to clearness index values, and empirically deriving irradiance weights. The normalized irradiation can then be used to forecast photovoltaic fleet energy production.

Abstract: Normalization coefficients in are computed for positron emission tomography (PET) continuous bed motion acquisition (CBM). The normalization coefficients for the lines-of-response in CBM account for the change in decay of the injected isotope over time and/or changes in velocity of the bed motion.

Abstract: Probabilistic forecasts of the expected power production of renewable power sources, such as solar and wind, are generally provided with a degree of uncertainty. The expected power production for a fleet can be projected as a time series of power production estimates over a time period ahead of the current time. The uncertainty of each power production estimate can be combined with the costs and risks associated with power generation forecasting errors, and displayed or visually graphed as a single, deterministic result to assist power grid operators (or planners) in deciding whether to rely on the renewable power source.

Abstract: An electronic inspection apparatus includes a probe, a sensor, a memory unit, and a controller. The apparatus senses a condition, and stores data representative of the sensed condition at a high bit rate. The inspection apparatus transfers the sensed data to a computing device or database via a lower bit rate. In one embodiment, a data queue or memory unit of a temperature probe temporarily stores data before transmitting the data to a computing device (e.g., a mobile device). The method of the present invention provides two separate data logging parameters: (1) how fast to read and log data which determines a data logging period and (2) how fast to send the data to the mobile device which determines a data transmit period. Thus, the data transfer period is isolated or decoupled from the data logging period.

The method also includes determining the ambient temperature (Tamb), calculating an estimated maximum power point voltage (Uest) by using maximum power point current (IMPP) and the determined ambient temperature (Tamb), comparing the estimated maximum power point voltage with the determined maximum power point (UMPP), and determining on the basis of the comparison whether the generator is operating under uniform conditions or in conditions with two maximum power points.

Abstract: Methods and systems for determining and removing swell noise from electric field data collected from streamers towed at different are disclosed. In one aspect, a first set of streamers called upper streamers is towed at a shallow depth, and the second set of streamers called lower streamers is towed below the upper streamers. Receivers located along the streamers measure surrounding electric fields and produce electric field signals. A proportionality parameter is calculated as a function of the electric field signals generated by vertically aligned receivers. The proportionality parameter can be used to calculate an approximate swell noise that is used to remove swell noise from electric field data measured by the receivers.

Abstract: This disclosure concerns estimating the number of people within building-based device networks. Increasingly, local area network (LAN) devices are capable of sensing people (e.g. smart appliances). Features of building layout, and physical arrangement of devices provide that only a subset of sensor data patterns can be accounted for by a single user (e.g. simultaneous activation of a smart TV and a motion sensor). Over time, a central controller (e.g. LAN gateway) can gather these building-specific sensor patterns and learn single occupant characteristics for a network (e.g. features or boundaries of single occupant capability). In one embodiment, the central controller generates a single occupancy criterion (e.g. a building-specific test), comprising single occupant characteristics, operable to test a subset of sensor data for single occupancy.

Abstract: Disclosed is a system and method for processing LiDAR return data prior to analyzing the data to detect planted trees. LiDAR return data for an area in question is filtered to remove data that are not within a predetermined area of where trees have been planted. Planting data such as GPS data that is collected by tractors or other equipment records the location of where trees are planted. The planting data is used to filter the LiDAR return data by eliminating or ignoring LiDAR return data that are not within a buffer zone around the location where the trees have been planted. Once filtered, the LiDAR return data can be analyzed to detect trees or other items of interest in the LiDAR return data.

Abstract: A method and device for dynamically altering the signal-space-to-physical-space mapping database of a set of access points for use in localizing of an object, by obtaining a location profile for the object and obtaining an estimated location of an object by measuring the signal parameter induced by at least one access point and using the signal-space-to-physical-space mapping database for deriving an estimated location from the measured signal parameter, and determining whether the obtained estimated location complies with the obtained location profile for the object. If the obtained estimated location does not comply with the location profile, the mapping database is dynamically adjusted to obtain an adjusted signal-space-to-physical-space mapping database based on a difference between the measured signal parameter and the signal parameter corresponding with the signal space for the location expected based on the location profile.

Abstract: A wall area estimation system generates an estimated wall area measurement of a building based on the received roof measurements (e.g., those generated by, received from or found in a three-dimensional model of the roof) and a reference distance. The reference distance is a measurement indicative of a distance between the roof and a model ground surface placed on an image of the building where the walls of the building meet the ground. This reference distance may be used to determine how for down to extend the walls of the building (e.g., to a ground level) when building a three-dimensional digital model of the building to aid in generating wall area measurements. The resulting wall measurements, roof measurements, measurements of areas missing from the wall used to generate a wall estimate report, or a combined roof and wall estimate report including various different identifiers indicating the different features and measurements based on the three-dimensional model.
