20080265887 | SYSTEM AND APPARATUS FOR DETECTING GAMMA RAYS IN A PET/MRI SCANNER - A gamma ray detector ring for a combined positron emission tomography (PET) and magnetic resonance imaging (MRI) system is integrated into a radio frequency (RF) coil assembly such that the detector ring is integrated with a RF shield. Each gamma ray detector in the detector ring includes a scintillator component that emits light when a gamma ray is detected and a photodetector component designed to be sensitive to the frequency of light produced by the scintillator. A RF shield may be integrated into a detector ring such that the RF shield is positioned between the scintillator and photodetector components of each detector, thereby saving valuable radial space within the imaging system. Multiple such detector rings may be located adjacent to one another to increase axial coverage and enable three-dimensional PET imaging techniques. | 10-30-2008 |

20090117851 | QUALITY OF SERVICE SEEKER - This invention concerns quality of service (QoS) mapping in wireless space. QoS maps represent measurements, or predictions, of one or more quality of service metrics in the space. The maps are useful in the management of wireless communications systems. The map is comprised of several layers of information visit e at the same time. The a first layer shows the physical features within the space. Additional layers indicate the value of respective quality of service metrics at locations indicated by the first layer. Users of the communication network can contract with the service provider to have the selected services provided at respective selected service levels by using the map. | 05-07-2009 |

20130340039 | LOCATION-ENABLED SECURITY SERVICES IN WIRELESS NETWORK - A method, an apparatus, and a computer program product for providing location enabled security services in a wireless network. In the method, a network access request from a node requesting access to the wireless network is received. A probability level for a position for the requesting node is calculated using position information claimed by the requesting node and position information about the requesting node derived from signal measurements for the requesting node received by at least one existing authorized node in the wireless network. Access for the requesting node to the wireless network is denied if the probability level does not satisfy a specified threshold condition for network security. Access for the requesting node to the wireless network is granted if the probability level does satisfy the specified threshold condition. | 12-19-2013 |
