The invention relates to a security system designed to recognise, by means of the presence and/or content of a status enquiry signal of at least one security unit, whether or not at least one security unit is located inside the security zone. The security system includes an alarm generating unit which is designed to generate an alarm signal if it has been recognised that the at least one security unit is located outside the security zone. The invention further relates to a method for emitting an alarm signal, a bus with a security system and a use of a security system.

An information processing device that transmits a detection result to another device when abnormal detachment of a wearing device worn by a user is detected.

A safety alert system for alerting a user to a person, animal, or article unintentionally left in a vehicle includes an alert module that is configured to couple to an ignition key of a vehicle and sensing module that is configured to selectively couple to a person, animal, and article that is positioned in the vehicle. The alert module comprises a first transceiver, a first proximity sensor, and a first speaker. The sensing module comprises a second transceiver and a second proximity sensor, which is operationally coupled to the first proximity sensor so that a separation between the sensing module and the alert module is measurable. The second transceiver signals the first transceiver in event the separation exceeds a predefined distance, positioning the alert module to broadcast an alarm via the first speaker to alert the user that the person, animal, or article still is positioned in the vehicle.

A system enabling children for communicating with parent and friend through a wearable device is enclosed. The system includes a memory unit and a processor that executes a set of modules that includes an information exchange module 304, a digit code generation module 306, and a voice message transfer module 308. The information exchange module 304 exchanges and transfers information between the first child wearable device 104 and the second child wearable device 114 when the first child 102 chooses to add the second child 116 within a close proximity, to a contact list of the first child wearable device 104. The digit code generation module 310 generates a random digit code when the first child 102 chooses to add the second child 116 in a remote location, to the contact list of the first child wearable device 104.

A wireless asset location tracking system and related techniques are disclosed. The system may include one or more beacon tags and one or more micro-zone (mZone) transmitters disposed at designated locations. A given mZone transmitter may transmit an mZone signal including data pertaining to its identity, and thus location. A given beacon tag receiving the mZone signal may pull mZone identification data therefrom and relay it in its own beacon signal, along with other data. In this manner, a given mZone transmitter may provide information pertaining to the location within the host space of a given beacon tag within its transmission range. The beacon signal may be received by any gateway or reader device within range, and information therefrom may be delivered through the internet to a server database. The information stored at the server database may be accessed to monitor and track tagged assets and control overall system operation.

Various embodiments provide systems and methods for encouraging progress toward a lower level of monitoring for a monitored individual.

A system, management device, SCBA and wearable device are provided. In one or more embodiments, a wearable device for use with a self-contained breathing apparatus (SCBA) is provided. The device includes device processing circuitry configured to: determine a wireless personal accountability report (PAR) signal has been received, and transition into an alarm state based on the received wireless PAR signal. The alarm state configured to trigger at least one notification while in the alarm state where the triggering of at least one notification is configured to recur until an indication is received.

Active radio-frequency identification, RFID, tag, and a product surveillance method using active RFID tags. The method includes: transmitting (202), by an active RFID tag, continuously a signal comprising an own identifier according to a predetermined schedule; receiving (204), by the active RFID tag, continuously a plurality of signals comprising a plurality of foreign identifiers transmitted by a plurality of other active RFID tags according to the predetermined schedule; measuring (206), by the active RFID tag, a received signal strength indication, RSSI, of each received signal; storing (208), by the active RFID tag, each foreign identifier of a signal whose RSSI exceeds a predetermined strength threshold; detecting (210), by the active RFID tag, that a signal with a stored foreign identifier is no more received according to the predetermined schedule and marking (212), by the active RFID tag, said stored foreign identifier.

Various embodiments provide systems and method for monitoring individuals.

A vehicle occupant alarm assembly includes a remote unit that is carried by a caregiver driving a vehicle. The remote unit broadcasts a location signal. A base unit is attachable to a child that is seated in a vehicle and the base unit is in remote communication with an extrinsic communication network. The base unit receives the location signal and the base unit transmits an alert signal to the extrinsic communication network when the location signal falls below a pre-determined signal strength. The remote unit receives an alert from the extrinsic communication network when the base unit transmits the alert signal to the extrinsic communication network. In this way the remote unit alerts the caregiver that the child may be unattended in the vehicle.
