20160033652 | SURVEYING SYSTEM - A surveying system for a construction site has a restricted antenna system with a plurality of fixed location antennas each defined by a set of location data associated with a specific deployment position. The surveying system also has a computing device with a data processor and a display screen. A communications module establishes a data transfer link with the restricted antenna system over which spatial data for distances between current positions of the computing device and one or more of the plurality of fixed location antennas are received. The computing device is loadable with project drawings corresponding to the construction site and displayable on the display screen. A position marker is overlaid on the display of the project drawing at a position thereon corresponding to a computing device location value derived from the spatial data and the location data of one or more of the fixed location antennas. | 2016-02-04 |
20160033653 | Chromotropic Detection of Ionizing Radiation - A high contrast dosimeter is constructed where a plastic support is at least partially coated with a layer having a colored radical trapping compound. The plastic is a polymer that can contain a radiation sensitive plasticizer. The plastic forms radicals upon irradiation with high-energy (low wavelength) radiation. Upon diffusion of the radicals to the layer of radical trapping compound, reaction forms a compound with a different color than the radical trapping compound. In an embodiment of the invention, the plastic support is celluloid and the radical trapping compound is an azulenyl nitrone (AZN). | 2016-02-04 |
20160033654 | PHOTON-COUNTING TYPE X-RAY CT APPARATUS - Provided is a photon-counting type X-ray CT apparatus according to embodiments including a detector, a first collecting unit, a second collecting unit, and an image reconstruction unit. The detector detects an X-ray and outputs a signal. The first collecting unit collects count data of photons of the X-ray for every energy band with a predetermined time width by using the signal output from the detector. The second collecting unit corrects integration data obtained by integrating the signal with the predetermined time width by using the signal output from the detector. The image reconstruction unit corrects the count data by using the integration data. The image reconstruction unit generates a reconstructed image by performing a reconstructing process on the corrected count data. | 2016-02-04 |
