The present disclosure relates an evacuation management system, EMS, (40, 52, 60, 00, 200) operative to provide real-time evacuation information for evacuation of a building, triggered by alarm notification (S202). Based on determined (S214) precise real-time positions of personal ultra-wide band, UWB, devices, as determined by UWB real-time localization system, RTLS, a controller determines (S210) evacuation plans being personal UWB device specific in real-time. Based on individual evacuation plans and input from building facilities, real-time guidance information is defined (S208) and sent to each personal UWB device, providing guidance to person carrying said personal UWB device, in what direction to move (S212), to reach a safe area. Based on localization signals the UWB RTLSA then calculates updated positions of the personal UWB devices and sends to the evacuation management system. It is an advantage that trapped or injured people can be found, even in low visibility areas.

An alarm management system includes a control arrangement, an alarm device, a blockchain, a blockchain application, and a plurality of nodal access sites. The arrangement includes a processor and a storage medium. The device is configured to output an event signal to the control arrangement. The blockchain is stored in the medium, and includes a plurality of transaction types. Each transaction type includes at least one linked transaction, and the at least one linked transaction is time stamped. The blockchain application is stored in the medium, and is executed by the processor, and is configured to time stamp each one of the transactions. The blockchain is applied by the application to determine a current associated transaction with any one of the transaction types, and output data associated with the current transaction. The plurality of nodal access sites are configured to receive and output the data associated with the current transaction.

A detection system (10) for hazard detection is provided. The detection system (10) includes a control loop (16); an addressable base unit (18) connected to the control loop (16), the base unit (18) including a first near-field communication module (22) storing a unit address; and a mounting unit (20) removably coupled to the base unit (18), the mounting unit (20) including a second near-field communication module (24) operable to read the unit address from the first near-field communication module (22) and store the unit address so that the mounting unit (20) is thereby addressable via the control loop (16).

A system and method for quieting unwanted sound. As a non-limiting example, various aspects of this disclosure provide a system and method, for example implemented in a premises-based or home audio system, for quieting unwanted sound at a particular location.

An action detection unit (110) analyzes monitor data obtained by monitoring a monitoring place, and detects a relevant action performed at the monitoring place and having a characteristic that is common to a violating action. A situation analysis unit (120) analyzes visual data obtained by photographing the monitoring place, and detects a surrounding situation of an action position equivalent to a position where the relevant action was performed. The situation analysis unit decides a nuisance degree of the relevant action on a basis of the surrounding situation. A presentation control unit (130) determines an alert level on a basis of the nuisance degree. The presentation control unit presents presentation information corresponding to the alert level with using a presentation apparatus installed at the monitoring place.

A method for monitoring a dangerous situation in a space based on a frequency response pattern according to an embodiment includes loading, by a processing unit of a mobile terminal located in the arbitrary space, a setting value corresponding to an operational mode selected through control software installed on the mobile terminal, controlling, by the processing unit, a speaker of the mobile terminal to generate a frequency corresponding to the loaded setting value, receiving the frequency which was generated in the controlling and reflected in the space through a microphone of the mobile terminal, determining, by the processing unit, whether the dangerous situation occurred in the space by comparing the frequency response pattern with a preset reference value, and taking, by the processing unit, a follow-up action when it is determined that the dangerous situation occurred in the space by the determining.

One example method of operation may include identifying an emergency location based on a received emergency communication, determining enhanced information is available in a memory for the emergency location, retrieving the enhanced information, and forwarding the enhanced information to one or more emergency service entities and one or more registered devices located at the emergency location.

Logical boundaries enclosing a physical area are defined. A segment of the logical boundaries is defined as a directional gate, wherein traversing the gate into the physical area is defined as an ingress and traversing the gate out of the physical area is defined as an egress. The directional gate is monitored, and ingresses and egresses are detected. An occupancy count of the physical area is maintained, based on monitoring the gate and detecting ingresses and egresses. One or more conditions are tracked in addition to the occupancy count. Artificial intelligence (AI) processing is applied to the maintained occupancy count and the additional tracked condition(s), in real-time as the monitoring, maintaining and tracking are occurring. One or more responsive actions are automatically taken as a result of applying the AI processing to the maintained occupancy count and the additional tracked condition(s).

A graphical audio station of a nurse call system is operable to permit a user to perform one or more of the following functions: establish a two-way voice communication link with another computer device in another patient and/or with a another computer device located in another staff work area and/or with a wireless communication device carried by caregiver and/or with a telephone of the healthcare facility; broadcast a voice page to a group of other selected computer devices; compose and send a text message to a portable device that is carried by a caregiver and that has wireless communication capability; browse web pages and/or view multimedia content, such as videos, hosted on servers of the healthcare facility and/or that are accessible via the Internet; view and/or acknowledge and/or answer and/or cancel alerts or nurse calls originating in a plurality of patient rooms.
