This disclosure concerns the determination of improved exposure parameters of an image capturing device, such as a multi-spectral or hyper-spectral camera. A processor receives or determines image values for multiple points of an image and receives first one or more exposure parameters that were used to generate the image values.

Finally, the processor determines the one or more improved exposure parameters of the image capturing device, such that the one or more improved exposure parameters adjust the received or determined image values towards the enhanced image values. When the exposure parameters are used for capturing a further image, the further image will be enhanced. |

Application based hardware identifiers
An application based hardware identifier is generated for an application on a device. The application based hardware identifier is generated based on both information describing the application and information describing one or more hardware components of the device. The application based hardware identifier can also optionally be based on an identifier of a user of the device. The application based hardware identifier can be provided by the application to a service provider, allowing the service provider to associate the application based hardware identifier with a particular user or user account.

Fabric-based anonymity management, systems and methods
Based on a hidden service address table stored in a memory, a virtual circuit related to a hidden service is mapped to a corresponding port-level channel based on the hidden service's address. Data associated with the hidden service is routed between the virtual circuit and the port-level channel. This enables binding of high level anonymity protocols to low level communication services of a network fabric and ensures that other nodes in the network fabric can leverage fabric-hosted hidden services without requiring updates to an existing anonymity protocol. |

Intercepting intra-network communication for smart appliance behavior analysis
A system and method for intercepting intra-network traffic for smart appliance behavior analysis. A network traffic hub is configured to intercept network traffic between a switch and a router. A smart appliance sends a message to the router, such as a DHCP request when the smart appliance joins the network. The router sends a response to the smart appliance. The network traffic hub intercepts and modifies the response to instruct the smart appliance to send all future intra-network traffic through the network traffic hub and the router. In some embodiments, the network traffic hub alters a network mask in the response message to instruct the smart appliance to send traffic through the network traffic hub. The network traffic hub then extracts data from the network traffic and uses that data for behavior analysis of smart appliances. |

Furthermore, the apparatus has a phase setter (5), which effects phase setting of the electromagnetic radiation of the pulses laser (1). In accordance with the invention, the offset frequency of the spectral lines of the optical frequency comb is adjustable by time-proportional phase setting by means of the phase setter (5). |

Limited power outlet with changeable protective bezel
A jack receptacle for a plug connector is configured with a receptacle profile having one or more keying features disposed on a removable bezel which correspond to complementary keying features formed on a plug connector. The jack receptacle with removable keyed bezel can be configured to allow only plug connectors with the corresponding keying features to mate therewith, while preventing plugs without the corresponding keying features from mating. These features can prevent non-certified devices from being plugged into a power-delivering data circuit, and also permit the keying of receptacles with removable bezels based on ratings for transmission of different power levels. Other embodiments of the keyed jack receptacle can be configured to allow both plug connectors with the corresponding keying features and plug connectors without the corresponding keying features from mating therewith. This provides a means to migrate specific circuits within the system to limited power usage. |
