Currently, users in an artificial reality (XR) experience cannot travel with a group to a specific destination or between destinations (e.g., to and from virtual worlds, levels, applications, etc.). Thus, some implementations assign users within a group in a multiplayer XR experience (e.g., a virtual lobby) a same session identifier. When the users select a destination, some implementations can provide a computing system hosting the destination with the session identifier associated with the users, such that the hosting computing system can ensure that the users travel to the same instance of the destination together. If a user does not already have the destination installed, some implementations can allow the user to acquire access rights to the destination, then travel to the same instance of the destination as the other users. |

Techniques and architecture are described for initializing, reviewing/approving, and deploying changes within a network. Each change is associated with a particular change ticket. When a change needs to be rolled back, the original change ticket may be analyzed to determine what actions need to be performed to roll back the change. A plan of the needed actions may then be presented to a reviewer in a rollback ticket. The original change ticket may be cancelled and a new ticket, e.g., the rollback ticket, may be prepared that includes the plan for the rollback, e.g., the one or more actions needed to roll back the initial change. In configurations, a change ticket may include multiple changes and thus, for rollback, either all the changes associated with the change ticket may be rolled back or only the last change or action that was initially made may be rolled back. |

System and method for driving assistance along a path
Various aspects of a system and method for driving assistance along a path are disclosed herein. In accordance with an embodiment, a unique identifier is received from a communication device at an electronic control unit (ECU) of a first vehicle. The unique identifier is received when the first vehicle has reached a first location along a first portion of the path. A communication channel is established between the first vehicle and the communication device based on the received unique identifier. Data associated with a second portion of the path is received by the ECU from the communication device based on the established communication channel. Alert information associated with the second portion of the path is generated by the ECU based on the received data. |

Detecting abnormal events for a monitoring system
Systems, apparatuses, and methods are described for detecting a state transition for sensors of a monitoring system, and determining whether the state transition is abnormal such that further action is warranted. The determination may be based on a history of state transitions in the monitoring system, and may be based on whether the same state transition has previously occurred at a corresponding time in the history, whether the new state has previously occurred following the corresponding time in the history, and other factors. |

Watching support system, watching support device, and watching support program
A watching support system ensures that a person in charge of watching can be efficiently and effectively arranged in a watching system capable of detecting a position of an object person with high power efficiency and accuracy. An object person terminal transmits identification information via short-range wireless communication. A detection terminal is carried by a person in charge of watching who detects and performs watching over an object person, and transmits the identification information transmitted from the object person terminal that can be communicated to a server. The server specifies the position of the object person terminal based on information transmitted from a detection terminal, acquires watching need information regarding a necessity of watching by the person in charge of watching, and outputs an instruction regarding watching to the detection terminal based on the watching need information. |

Apparatus for enabling installation of recessed ceiling components
One or more embodiments of the invention introduces a novel recessed mounting system for ceiling components such as smoke detectors, improving their installation, aesthetic integration, and functionality. By recessing all electronics into the ceiling, the system achieves a streamlined appearance, leaving only the sensing element exposed. The system comprises three major components: the recessed housing, the sensor module, and the finish trim. The recessed housing seamlessly integrates with remodel and new construction projects, providing an unobtrusive look. The sensor module supports various sensor types, ensuring adaptability to different detection needs. The finish trim offers customization options, enabling field changes from round to square shapes and providing a selection of custom finishes to match architectural elements. This innovative system enhances the aesthetic appeal, smoke detection capabilities, and ease of installation of smoke detectors in residential, commercial settings. |

Obscuration cloud generator
An obscuration cloud generation device (100) is disclosed. It may comprise a container (104) for holding an obscuration cloud generating canister (110), wherein a composition for forming the obscuration cloud is emitted from the obscuration cloud generating canister (110) in response to activating the obscuration cloud generating canister (110). It may further comprise a housing (101) having a frame (103) wherein the container (101) is removably held inside the frame (103). The housing (101) has an opening (105) and a door (102), the door (102) being movable between a closed state for covering the opening (105) and an open state for emission of the composition from the device (100) via the opening (105). The opening (105) is shaped and sized to allow the container (104) to be extracted from the housing (101) through the opening (105) when the door (102) is open to replace the obscuration cloud generating canister (110). |
