In an approach to invention purpose, for controlling evacuation of a plurality of individuals carrying corresponding portable computing devices from a venue having a plurality of exits associated with corresponding exit computing devices, wherein the method comprises, under the control of the portable computing device of each of the individuals. One or more computer processors receive one or more of evacuation messages of wireless type each being transmitted by a source entity. The one or more computer processors select a selected evacuation message of the received evacuation messages according to the hop number of the received evacuation messages. The one or more computer processors subscribe to a directed exit being set to the origin exit of the selected evacuation message.

A projection processing device comprises a processor control unit that acquires, in response to acceptance of input information, projection position information associated with the input information, and instructs a projector to emit light or project an image enabling a user to identify a position based on the acquired projection position information.

A user, such as an elderly person, may be assisted by an assistance device in his or her caregiving environment that operates in conjunction with one or more server computers. The assistance device may execute a schedule of assistance actions where each assistance action is associated with a time and is executed at that time to assist the user. An assistance action may present an input request to a user, process a voice input of the user, and analyze the voice input to determine that the voice input corresponds to a negative response event, a positive response event, or a non-response event. Based on the categorization of one or more voice inputs as negative response events, positive response events, or non-response events, it may be determined to notify a caregiver of the user, for example where the user has not responded to a number of assistance actions.

A visual signaling system includes smart signage with a set of three or more lights visible from a single direction. Activation of the lights in a first pattern indicates a hazard and for individuals to move away from the sign. Activation of the lights in a second pattern indicates safety and for individuals to move toward the sign. Activation of the lights in a third pattern indicates a need for caution and for individuals to refrain from approaching the sign. The visual signaling system may include a plurality of smart signs which display different patterns on different signs depending on the location of each sign relative to the hazard, thereby guiding individuals away from the hazard.

A computer system in included in a system for providing wildfire evacuation support. The computer system operates to obtain sensor data that represents a wildfire in a target region from a UAV which is deployed within the target region, obtain a current location of an individual in a hazardous situation in the target region, and obtain a desired destination for the individual in the target region. Based on the sensor data, the computer device identifies one or more danger zones that pose a fire-related threat to the individual, and determines at least one evacuation path that extends from the current location to the desired destination while avoiding the one or more danger zones. The computer system may be located at the UAV or on a central computer resource in communication with the UAV.

This disclosure relates to an intelligent smart glasses that may be worn by a customer. The smart glasses may sense cash information on automated teller machine (“ATM”). The smart glasses may accordingly split up a cash transaction across various ATM units in close to proximity to the customer. The smart glasses may split a requested cash transactions among various ATMs so that if the desired amount/denomination of cash is not available at an ATM to the customer, the customer is seamlessly directed to one or more other ATMs that are capable of dispensing the desired amount of cash.

A passenger aircraft includes a plurality of passenger seats arranged in seat rows, and a disembarkation guidance system. The disembarkation guidance system includes a plurality of electronically operable visual indicators, each of the plurality of electronically operable visual indicators being assigned to a respective seat row. The disembarkation guidance system further includes an indicator control device coupled to each of the electronically operable visual indicators. The indicator control device is configured to individually control electronically operable visual indicators to indicate passengers in the assigned seat row whether they are permitted to disembark the passenger aircraft.

A system for generating emergency egress advisement for a building having at least one first computing device that determines a floormap and generates initial emergency egress advisement for the building and at least one second computing device that improves generation of initial emergency egress advisement. The second computing device can receive the initial emergency egress advisement, iteratively train a model for the building by correlating the initial emergency egress advisement to corresponding information about intended egress outcomes for different emergency situations in the building across one or more model layers using one or more machine learning algorithms, predict, based on real-time information about the emergency and historic user presence information, presence and location information of users in the building, generate egress routes that can be used by the users, and update, based on a trained model and the generated egress routes, the initial emergency egress advisement for the building.

Provided is a wearable device to provide guidance to a user related to a movement trajectory path of an exercise. The wearable device includes a band, a plurality of vibration motors, at least one processing unit, and a processor. The band is configured to be disposed on a body part to be moved in the exercise. The vibration motors are connected about the band and configured to vibrate when activated. The processing unit is connected to the band and is configured to determine motion data of the motion processing unit as the body part is moved in the exercise. The processor is configured to determine three-dimensional orientation of the band in relation to the trajectory path based on the motion data of the at least one motion processing unit, and configured to activate one or more of the vibration motors to provide guidance to the user based on the trajectory path.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for group identification and monitoring. The methods, systems, and apparatus include actions of determining, using one or more first frames of a video sequence, that two people each of whom is depicted in at least one of the first frames satisfy a grouping criteria that indicates that the two people should be grouped for video analysis, determining, using one or more second frames of the video sequence at least some of which were captured after the one or more first frames and which depict at least one of the two people, that the two people satisfy a degrouping criteria that indicates that the two people should not be grouped for video analysis, determining that a physical distance between the two people violates a distance criteria, and providing an alert that the distance criteria is violated.
