This patent document describes, among other things, methods, apparatus, and systems for tracking those resources that a server has pushed to a client, e.g., using the HTTP 2.0 or other server push mechanism. Pushed resources may be cached at the client. By tracking such pushed resources, a server can avoid pushing such cached resources in response to subsequent requests from that client; doing so would be wasteful if the client already has the resource cached. Among other things, techniques for storing, encoding, organizing, and managing data about pushed resources in cookies are disclosed. |

High energy broadband laser system, methods, and applications
The present invention demonstrates a technique for achieving milli-joule level and higher energy, broad bandwidth laser pulses centered around 2.4 micrometer with a kilohertz and other repetition rate. The key to such technique is to start with a broadband micro-joule level seed laser at around 2.4 micrometer, which could be generated through difference frequency generation, four-wave mixing process and other methods. This micro-joule level seed laser could then be amplified to above one milli-joule through chirped pulse amplification in a Cr2+:ZnSe or Cr2+:ZnS crystal pumped by a commercially available Ho:YAG or other appropriate suitable lasers. Due to the high seed energy, fewer gain passes are needed to achieve a milli-joule level output thus significantly simplifies laser architectures. Furthermore, gain narrowing effect in a typical chirped pulse amplifier is also mitigated and thus enable a broadband output. |

Profile element comprising lighting means accommodated therein
An illumination or display element includes a hollow profile (1) which has a recess extending in a longitudinal direction for receiving a plurality of lighting means (2) and the electric lines thereof. The hollow profile includes two parallel, spaced apart limbs connected by a base body, and the recess is located between the limbs. The recess of the hollow profile is closed by a foil extending at least over a part of an outer lateral surface of the limbs. The foil may completely surround the hollow profile. The lighting means may face the base body of the hollow profile, provided that at least the base body of the hollow profile is transparent or translucent. |

Data processing system with machine learning engine to provide roadside assistance functions
Systems, methods, computer-readable media, and apparatuses for receiving requests for roadside assistance, generating user interfaces and using machine learning to generate roadside assistance instructions are provided. In some examples, a request for roadside assistance may be received. A user and one or more partners may be identified based on the request. In some examples, a profile associated with the user, partner or the like may be identified. A user interface may be generated based on the profile and may include features unique to the profile, partner, or the like. In some arrangements, the interface may include a first portion and a second portion. Selection of an option from the first portion may cause the system to identify data for display in the second portion and cause the data to be displayed in the second portion. Machine learning may be used to determine or identify one or more roadside assistance instructions and a roadside assistance instruction may be generated and executed. |

System and method for vision sensor detection
Vision sensor detection systems and methods for mobile platforms that proactively prepare for impending lighting scenarios. The method includes determining or predicting a lighting scenario (LS) as a function of GPS data and wirelessly received mapping data. An on-board camera system is then operated in the LS using an associated predefined profile (PDP) having a tone-mapping setting associated with the LS. Received sensor data and camera data is used to confirm each predicted and current LS; Each predicted LS change results in retrieval of an associated PDP with its tone-mapping setting. Each confirmed LS results in using the sensor data and camera data to customize the tone-mapping setting. The method cycles during operation of the mobile platform. |
