As such, a user can provide a freeform input path that resembles a path of interest by the user, but is not as precise as desired. Based on existing paths in the electronic drawing, a path suggestion(s) can be generated to rectify, modify, or replace the input path with a more precise path. In some cases, a user can then select a desired path suggestion, and the selected path then replaces the initially provided freeform input path. |

The residuals are aligned to corresponding acoustic firing pulses of the downhole acoustic tool. The aligned residuals are subjected to a second low-pass filter. The measured waveforms are aligned to the corresponding acoustic firing pulses. Noise associated with the downhole acoustic tool is removed from the pulse-aligned, measured waveforms utilizing the filtered residuals. |

Thus, the certified checkpoint state represents an agreed-upon state, and that one or more subsequent operations on the ledger are relative to that agreed-upon state. Preferably, before a checkpoint is certified, it must be consistent, meaning that all validating peers have reached the same value for the checkpoint. Preferably, the checkpoint is a compression of the current blockchain world state into a compact representation (e.g., a hash) of the ledger that based on an agreed-upon consensus protocol is consistent across the (validating) peers. |

Automatically collecting data regarding assets of a business entity
A system to automatically gather attribute data about elements such as networks, network interface cards, operating systems, device types, installed software, processes in execution, financial data, etc. in an organization or a designated subset of the organization. Fingerprint files are used, each fingerprint file corresponding to an element of a specific type and each containing a list of attributes that will be found if that element exists in the system. Each fingerprint contains or points to one or more collection instructions which control a data collector process to attempt to gather attribute data. Each fingerprint contains or points to rules that are used to analyze the attribute data gathered to calculate the probability that the element exists. The rules can be fired sequentially, in if-then-else fashion or can be incorporated in a script in loops and with mathematical manipulations, tests and branching for more sophisticated analysis. Fingerprints can be turned on and off by configuration data and can be used in a logical order to do discovery without any prior knowledge of the systems being analyzed. A refresh schedule and collection calendar control how often the fingerprints are used in some embodiments, and collected data is stored with time stamps to enable analysis of changes in the data over time. |

Smart shelf system that integrates images and quantity sensors
A system that integrates camera images and quantity sensors to determine items taken from, placed on, or moved on a shelf or other area in an autonomous store. The items and actions performed may then be attributed to a shopper near the area. Shelves may be divided into storage zones, such as bins or lanes, and a quantity sensor may measure the item quantity in each zone. Quantity changes indicate that a shopper has taken or placed items in the zone. Distance sensors, such as LIDAR, may be used for shelves that push items towards the front. Strain gauges may be used for bins or hanging rods. Quantity changes may trigger analysis of camera images of the shelf to identify the items taken or replaced. Images from multiple cameras that view a shelf may be projected to a vertical plane at the front of the shelf to simplify analysis. |

Reservation system and method
A reservation system for travel, accommodation, venue ticketing and other purposes may be accessed on-line, for example via a social networking website. A user enters their social networking identification into the reservation system. When a subsequent user makes a reservation, they also enter their social networking ID and the system retrieves a list of associated parties from the social networking website, which may be a friends or contacts list, and searches for reservations made by any of those parties which have an overlapping criterion, such as date and destination. The overlap may be used to identify parties who will be at the same destination at the same time as the subsequent user, and/or are travelling on the same flight or journey. On check-in, the system may use the list of associated parties to notify the party checking-in that one of their friends or contacts has also checked-in. |

Selective switching of frequency multiplexed microwave signals using cascading multi-path interferometric josephson switches with nonoverlapping bandwidths
A cascading selective microwave switch (cascade) includes a set of Josephson devices, each Josephson device in the set having a corresponding operating bandwidth of microwave frequencies, wherein different operating bandwidths have different corresponding center frequencies. A series coupling is formed between first Josephson device from the set and an nth Josephson device from the set. the series coupling causes the first Josephson device in an open state to reflect back to an input port of the first Josephson device a signal of a first frequency from a frequency multiplexed microwave signal (multiplexed signal) and the nth Josephson device in a closed state to transmit a signal of an nth frequency in the multiplexed signal from an input port of the nth Josephson device to an output port of the nth Josephson device. |
