Techniques for determining information about an incident by one or more sensors in a streetlight, utility meter, and / or other device are described herein. A device proximate a sensor(s) can process sensor data to determine an incident type and / or an incident location in an environment. For example, the device can detect presence of a weather event, an accident, a crime, a crowd control event, a fire, a flood, and so on. In some examples, the device can identify other sensors in a vicinity of the incident (e.g., attached to other streetlights, utility meters, transformers, etc.), and select sensors for gathering additional information about the incident based on the incident type and / or the incident location.

The invention described herein relates to an emergency aerosol retainer, designed to securely hold the aerosol canister while providing quick access in emergency situations. The aerosol retainer features a durable and lightweight construction with an ergonomic design which allows for easy attachment to belts, backpacks, vehicles, or structures. The aerosol retainer facilitates rapid deployment in emergency situations by minimizing interference when deploying the aerosol spray. This invention offers enhanced safety and convenience for hikers, campers, motorists, law enforcement, firefighters, and others by ensuring that emergency aerosol sprays are always within reach. The primary initial application for this invention is for wildlife deterrent spray, such as bear spray.

This specification provides a robot swarm control system and method. The robot swarm control system includes a swarm controller and multiple robots. When a target robot among the multiple robots forms a temporary wired communication link with the swarm controller via a physical connection interface, it reads the controller identification information corresponding to the swarm controller and establishes a communication identity binding relationship with the swarm controller based on the controller identification information. A wireless channel for bidirectional communication with the swarm controller is established based on the communication identity binding relationship. The wireless channel is constructed based on a radio frequency communication chip and operates in the target frequency band. When the swarm controller establishes wireless channels with each of the multiple robots, it responds to robot control operations by sending control commands to each robot through the wireless channels established with each robot. The target robot verifies the control commands through a hardware protocol layer. If the verification passes, it executes the motion task associated with the control commands.

An electronic ticket processing system that includes the management of a venue with auction-based, during event, peer-to-peer electronic ticket exchanges. The peer-to-peer during event ticket exchange may be limited by the location of the electronic device of a user and may allow the event attendees enhancement of their experience (e.g. by upgrading their seat location or rights to access). In some embodiments, the during event peer-to-peer ticket exchange may be encouraged or controlled by the venue based on certain factors, such as, broadcasting considerations, crowd control, analytics, to encourage consumer spending, memberships, and / or other real time updates (e.g., weather, game scores, security concerns).
