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.

A device for estimating a fixed position of a wireless communication is provided. The device comprises a radio connected to an antenna array, a memory and a process. The radio can receive a first signal transmitted from a first direction by the wireless communication device to the movable device, and a second signal transmitted from a second direction by the wireless communication device to the movable device. The processor can calculate a first angle of arrival (AOA) a second AOA. The processor can estimate the fixed position of the wireless communication device based on the first AOA, the second AOA, the first position and the second position.

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.

Determining a user identity associated with a detected device is disclosed. A presence of a device at a location is detected based at least in part on traffic data obtained from a sensor. An identity of a user associated with the device whose presence is detected at the location is determined. An action is performed based at least in part on the determined user identity.

Disclosed is a system including one or more smart utilities, and a personal smart device configured to: communicate with the one or more smart utilities over one or more networks, instruct the one or more smart utilities to return self-identifying information, and instruct one or more of the one or more smart utilities, individually or as a subgroup, to activate an identifying beacon.

The embodiments of the present application provide an indoor positioning system, including an information source module, a gateway, a first leaky cable and a first positioning device; where the information source module is connected to a first end of the first leaky cable through a feeder; the first positioning device is arranged between the first end of the first leaky cable and the feeder, and the first positioning device is configured to transmit a positioning signal through the first leaky cable, so as to enable the terminal to perform positioning according to the positioning signal. There is no need to set up a new positioning system, thus reducing costs for network construction as well as space requirements for the network construction.

In accordance with an embodiment, an information processing apparatus uses a reader for reading tag information from an RF tag added to each of objects, to thereby manage the objects. The information processing apparatus includes a display device and a controller. The controller acquires information for identifying an allocated range of management of the objects at the information processing apparatus. The controller causes the display device to display individual progress information indicating by what degree of the allocated range reading by the reader has been finished.

High-accuracy locating systems and methods are used for determining successful caregiver rounding, monitoring whether housekeepers have properly cleaned patient beds, or determining whether patients have ambulated sufficient distances during recovery. Patient beds having at least two locating tags are used for establishing patient care zones around the patient beds. Locating anchors and equipment tags are moved around a patient room to determine optimum locating anchor placement within the patient room based on signal quality values. A locating tag on a patient bed switches roles to operate as a locating anchor in response to the patient bed becoming stationary. A locating tag has a digital compass which is used to determine a field of good ranging relative to a front of a caregiver wearing the locating tag.
