20120131155 | CONTEXT-BASED DYNAMIC POLICY SYSTEM FOR MOBILE DEVICES AND SUPPORTING NETWORK INFRASTRUCTURE - Systems and methods dynamically adapt network policies for mobile devices by accessing context-based values to allocate or restrict capabilities on the mobile devices or within the network. Context-based values may include position or velocity as well as more general environment features such as proximity of other devices, the presence or absence of other wireless signals or network traffic, parameters measured by local or remote sensors, user credentials, or unique user or signal inputs to the device. Relevant capabilities may include access to hardware and software interfaces and related parameter sets including priority settings. | 05-24-2012 |
20130067044 | MANAGING NETWORK INTERACTION FOR DEVICES - Signals from an unidentified device at a location related to a communications network are correlated with identification patterns of managed devices to identify whether or not the unidentified device corresponds to a managed or unmanaged device in the communications network. Both managed and unmanaged devices can be tracked, and network interaction can be managed for devices that are identified as managed devices. | 03-14-2013 |

20100289408 | SINGLE PHOTON SOURCE - A photon source capable of emitting, for example, a single photon or a single pair of photons on demand. The photon source may include an excitation region where a single instance of a quantum system is excited using excitation energy. A Stimulated Raman Adiabatic Passage (STIRAP) technique can be used for exciting the quantum system to a desired energy level. The photon source may include a photon emission region physically displaced from the excitation region. A transport device can be used for controllably moving an excited quantum system from the excitation region to the photon emission region. The photon emission region may include a resonant cavity tuned to the de-excitation frequency of the quantum system for inducing de-excitation of the quantum system and emission of a photon. The photon emission resonant cavity may be switchably coupled to an output port by a tunable resonant cavity coupling device. | 11-18-2010 |

20110248651 | TEMPERATURE STABILIZED MICROWAVE ELECTRON GUN - The temperature rise due to the backstreaming electrons is canceled by an equal and opposite fall in temperature at the surface of the cathode due to the conduction of heat deposited at the surface immediately prior to the microwave pulse by a pulsed laser focused to uniformly illuminate the cathode surface. Variations in temperature across the surface of the cathode attributable to the non-uniform spatial distribution of the backstreaming electrons may be compensated using a second laser pulse fired during the RF pulse to maintain constant thermal power input across the surface of the cathode during the RF pulse. This second pulse can also be used to compensate for the time-dependent rate of decay of temperature due to conduction of the heat deposited by the first laser into the body of the cathode. | 10-13-2011 |

20140235231 | SYSTEM OF EDGE BYTE CACHING FOR CELLULAR NETWORKS - The present invention is a method and system that reduces the amount of data traffic across communication links in a cellular network. In this system, the cellular device of a user receives and stores state information about a byte of data. During the implementation of the method of this invention, when a user desires to retrieve dam from the Network Core, tokens containing a description of the state information for the requested data are sent to the cellular device. The cellular device can then have these tokens resolved by a Node B cell site that has stored the requested data. This approach reduces the need to resend the data from the Network Core over communications links. Further, the cellular devices can freely move from cell site to cell site with little interruption or loss of information. | 08-21-2014 |

20140013492 | PROTECTIVE HELMET FOR MITIGATION OF LINEAR AND ROTATIONAL ACCELERATION - Embodiments provide protective helmets configured to protect the head from linear and rotational acceleration in an impact. In various embodiments, the helmets may include an outer layer, an inner layer, and at least one intermediate layer coupled to the outer and inner layers by alternate fixation sites, thereby providing a suspension between the outer and inner layers. In various embodiments, the intermediate layer may be made from a honeycomb material, such as an aluminum honeycomb. In use, in-plane deformation of the honeycomb may allow for translation of the outer layer in a substantially tangential direction relative to the inner layer, thereby mitigating rotational acceleration imparted by the tangential impact component. Additionally, crumpling of the honeycomb in a substantially non-elastic manner may deplete impact energy to minimize the elastic rebound that can contribute to linear and rotational head acceleration, thereby mitigating linear acceleration imparted by the perpendicular impact component. | 01-16-2014 |

20110319942 | FLEXIBLE PLATE FIXATION OF BONE FRACTURES - Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone. In various embodiments, the systems and plates may provide elastic suspension of the receiving holes relative to the osteosynthesis plate. This elastic suspension may promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments, for instance if fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate may enable small, controlled amounts of relative motion between bone fragments connected by the plate, which may promote fracture healing by callus formation. | 12-29-2011 |

20130204304 | BONE PLATE FOR ELASTIC OSTEOSYNTHESIS - Embodiments provide a method and device for plate osteosynthesis of a bone fracture that allows angle-stable fixation of the bone fracture, while permitting elastic axial motion at the fracture site in a controlled, symmetric manner to stimulate fracture healing. Embodiments pertain to a bone plate having an outer surface and a bone-facing surface. The bone plate incorporating internal sliding elements containing a threaded receiving hole for bone screws that have a correspondingly threaded screw head. The sliding elements undergo controlled displacement parallel to the longitudinal axis of the plate but are substantially constrained against displacement perpendicular to the longitudinal axis of the plate. The bone screws with threaded heads may be rigidly fixed to the threaded receiving holes in the sliding elements without compressing the bone plate onto the bone surface. Sliding elements are elastically suspended inside the bone plate and undergo dynamic motion. | 08-08-2013 |
