A passenger tracking system that combines fobs carried by passengers and a passenger detector that detects when a fob is nearby. The fobs are battery powered and consume very little power; therefore, they can be sealed and waterproof, and may last for years before replacement. A fob is asleep until awakened by a short-range magnetic field broadcast by the passenger detector. After awakening, the fob listens for an encrypted message from the passenger detector, and responds with an encrypted response that contains the fob's identity. Tracking is secure because a fob is completely invisible unless and until it receives a magnetic field of the correct frequency and time-varying pattern, and an encrypted request message from an authorized sender; responses are also encrypted so that listeners cannot discover the fob's identity. The system is suitable for example for tracking schoolchildren entering or exiting a school bus.

A method of monitoring objects capable of wireless communications is provided. The method comprises detecting an activity performed by a user of a wireless communications device, acquiring information identifying an expected set of objects which are associated with the detected activity, determining whether at least one of the objects in the expected set is not in proximity of the wireless communications device, and if so notifying the user that at least one of the objects in the expected set is not in proximity of the wireless communications device.

A method for assessing health risk of a resident at a facility includes: tracking a first series of locations of a first wearable device associated with a resident of the facility; and tracking a first series of activities detected by the first wearable device; calculating a baseline action profile of the resident based on the first series of locations and the first series of activities; tracking a second series of locations of the first wearable device; tracking a second series of activities detected by the first wearable device; calculating a second action profile of the resident based on the second series of locations and the second series of activities; and in response to a deviation between the baseline action profile and the second action profile exceeding a deviation threshold, transmitting a prompt to a care provider associated with the facility to investigate a health status of the resident.

A device for preventing mobile phone loss for reducing the times of erroneous occurrences of an alarm, and to a method for providing an alarm for mobile phone loss prevention are disclosed. A device for preventing mobile phone loss according to an embodiment of the inventive concept includes a receiving unit that receives a predetermined signal from a pre-registered tag, a calculating unit that calculates a distance between a mobile phone and the tag based on the received signal, a controller that determines whether the mobile phone is in a predetermined safe place, and an alarm providing unit that provides an alarm for preventing the mobile phone loss based on whether the mobile phone is in the safe place and whether the calculated distance is equal to or greater than a predetermined reference distance.

An electronic sitter management system coupled to patient surveillance network having a plurality of video cameras, each camera transmitting a stream of surveillance video of a respective patient room. The sitter management system includes at least one sitter management device and a plurality of sitter devices. Each device being assigned a plurality of patient rooms and capable of receiving a plurality of streams of surveillance video for the corresponding plurality of patient rooms and simultaneously displaying a plurality of video images of the corresponding plurality of patient rooms. Each device is also capable of transmitting sitter device availability information to the sitter management device. The sitter management device being capable of recognizing a sitter device being unavailable and reassigning the plurality of patient rooms previously assigned to the unavailable device to other of the plurality of sitter devices that are available.

A check-in and tethering system for monitoring persons such as released in court-ordered supervised programs and a method for operating such a system is disclosed. The system includes a tethered mobile device that provides a check-in procedure that requires a response from a user of the tethered mobile device in the form of at least one of a device identifier from a monitored tethered device attached to the user, a biometric response, or a performed action by the user. The tethered mobile device determines whether the response is valid and transmits a notification to a monitoring center in response to the determination.

A tracking system determines a location of a tracking device associated with a user using one or more access points at the location. Each access point at the location is configured to detect and couple with the tracking device when the tracking device is within a communicative range of the access point. An access point provides updates on the tracking device's presence, as well as the tracking device's arrival to and departure from the communicative range of the access point, to a tracking server. The tracking server determines, from these updates, whether the tracking device is at the location. The user may be notified, via a mobile device, of the tracking device's location.

A system and method of alerting and responding to a school emergency allows faculty members to alert other faculty members and students of an educational institution of an emergency all at the same time. Moreover, the method allows faculty members to automatically contact a first responder in order to resolve the emergency. The faculty member is able to include details of an emergency such as, but not limited to, the location of the emergency and the type of emergency situation. Additionally, the method notifies parents after the emergency is resolved and provides a feature which allows parents to find their children using a global positioning system (GPS) module.

An object monitoring system including a plurality of location beacons, each location beacon being configured to generate a location broadcast message indicative of a beacon location and a tag associated with a respective object in use. The includes a tag memory configured to store object rules, a tag transceiver configured to transmit or receive messages and a tag processing device configured to determine context data at least partially indicative of a tag context by at least one of determining a tag location in accordance with at least one location broadcast message received via the tag transceiver from at least one of a plurality of location beacons and using stored context data, use the object rules and the context data to identify a trigger event, determine an action associated with the trigger event and cause the action to be performed.

In one embodiment, a method to monitor a proximity of an item within the confines of an automation system is described. The method may comprise setting one or more monitoring thresholds for an item. The monitoring threshold factors are communicating by a sensor proximate the item. The method may receive one or more notifications via the sensor that the item has exceeded at least one monitoring threshold and activating a monitoring aspect of the sensors based at least in part on the receiving. The method may monitor the item for one or more alarm thresholds based at least in part on the receiving. One or more alarms may be activated based at least in part on the monitoring.
