Various examples are provided for surveillance of an audio stream. In one example, a method includes identifying presence or absence of a sound type of interest at a location during a time period; selecting the sound type from a library of sound type information to provide a collection of sound type information; incorporating the collection on a device proximate to the location; acquiring an audio stream from the location by the device to provide a locational audio stream; analyzing the locational audio stream to determine whether a sound type in the collection is present in the audio stream; and generating a notification to a user or computer if a sound type in the collection is present. The device can acquire and process the audio stream. In another example, a bulk sound type information library can be generated by identifying sound types of interest including them based upon a confidence level.

Technologies and implementations for machine coordination and management of pickup of a minor with a guardian. The machine coordination and management may be facilitated by a child pickup module (CPM).

Disclosed herein are apparatuses and methods for managing building pathway information. A building and/or security management system can detect, based on receiving input from multiple sensor devices, a possible safety issue in a first pathway to an egress of a building, determine, based on detecting the possible safety issue and based on information regarding other pathways in the building, a second pathway to the egress of the building, and indicate at least the second pathway to another system.

An auxiliary system for intelligent well control includes augmented reality (AR) glasses, a server, and a first sensor group. The first sensor group is configured to collect real-time data of a wellbore and the surface and transmit the real-time data to the server. The server is configured to analyze a target pressure value of a choke valve of the surface according to the real-time data, obtain an actual pressure value of the choke valve of the surface from the real-time data, and transmit the actual pressure value and the target pressure value to the AR glasses. The AR glasses are configured to dynamically display the actual pressure value and the target pressure value in real time. Through the first sensor group and the server, the actual pressure value and the target pressure value can be accurately received by an operator in real time.

An image processing apparatus includes an image processing unit and a risk information generation unit. By processing at least one image, the image processing unit identifies a caution-requiring location being a location where a proximity indicator being an indicator related to a proximity state between a plurality of persons satisfies a criterion. The risk information generation unit outputs information indicating the caution-requiring location. For example, the information is displayed on a display unit through a display control unit. For each person, the image processing unit computes a first distance being the distance to the closest person to the person. Then, for each of a plurality of locations, the image processing unit counts the number of times the first distance has a reference value or less. Then, the proximity indicator is set by using the number of times the first distance has the reference value or less.
