A method for providing a low-power IoT communication-based geo-fence service on the basis of context awareness information of a position tracking device can comprise the steps of: allowing a context analysis engine of a position tracking device to measure context awareness information, obtained from peripheral sensors capable of receiving signals from the surroundings, such as a user's heart rate, body temperature, and movement state; determining whether a situation is emergency or ordinary on the basis of the context awareness information measured by the context analysis engine of the position tracking device; transmitting an emergency message and a measured position value to a server by using low-power IoT communication when the situation is determined to be emergency; after transmitting the emergency message, selecting a module capable of stably tracking a position from among a global positioning system (GPS), wireless fidelity (Wi-Fi) sniffing, Bluetooth low energy (BLE), and ultrawide band (UWB) modules of the position tracking device for position tracking; measuring mobile position information of a position tracking device user by using the selected position tracking module; checking whether the measured mobile position information, and the context awareness information, obtained from the peripheral sensors capable of receiving signals from the surroundings, such as the user's heart rate and body temperature can be transmitted by being converted through real-time communication; transmitting the context awareness information to the server at a frequent transmission cycle and at a data rate higher than that of ordinary times through real-time communication, if transmission through real-time communication is possible; receiving an emergency cancellation message from a server manager on the basis of the mobile position information and the context awareness information; and receiving the emergency cancellation message, and then transmitting, to the server, the context awareness information, obtained from the peripheral sensors capable of receiving signals from surroundings of the position tracking device user, such as the heart rate, body temperature and movement state, by converting the context awareness information through low-power IoT communication at a reduced transmission cycle and at a data rate lower than that of an emergency.

Disclosed are techniques for calculating a predicted location of a location tracking device. In an aspect, a wireless communications device detects a breach of a geofence made by the location tracking device, receives data representing a state of the location tracking device, the state of the location tracking device comprising at least a current location of the location tracking device and a velocity of the location tracking device, and determines, based on the data representing the state of the location tracking device, the predicted location of the location tracking device.

A tracking device with a screen that displays the mode of the tracking device on a screen. The device modes may include sleep mode, monitor mode, locate mode, and emergency mode. Each mode represents a frequency of transmission and which can be changed by the software developer or by the consumer in their software application. The sleep mode will be the fewest frequency pings and may be the mode in which the tracking device is operating while it is in a geofence. Monitor mode will be a higher frequency of pings and a locate mode may be yet a further increased number of pings per given time interval. The emergency mode will be entered when, for example, the pet is outside of the geofence and the owner needs to receive an intense number of pings to assure proper location, especially if the pet is moving. A charge may be made to the customer to enable readouts showing the mode and battery life left, and that the revenues derived from the customer, and in the case where the tracking device is used for pets, may be shared with the pet store. The user will be able to know the battery life remaining in any of the modes. The software application will communicate with the tracking device to change the frequency of the pings.

A wireless power transmitting device is disclosed. The wireless power transmitting device includes a first communicator comprising communication circuitry configured to communicate with a wireless power receiving device, a wireless power transmitter configured to supply wireless power to the wireless power receiving device, and a first controller configured to control the wireless power transmitter to supply initiating power for obtaining wireless power efficiency to the wireless power receiving device and to control the wireless power transmitter to supply driving power for driving an electronic device including the wireless power receiving device to the wireless power receiving device based on the wireless power efficiency being a predetermined value or greater based on information received from the wireless power receiving device through the first communicator.

The present invention provides an improved electronic fall monitoring system comprising a device having multiple sensor ports for flexibly monitoring various sensors associated with a single patient without requiring repeated connections and disconnections of sensors. With several sensors simultaneously connected at different locations, a processor can execute to ensure that only one sensor, corresponding to one patient, is monitored at any given time, including by triggering an alarm when a second sensor is triggered while a first sensor is in use. Accordingly, the system can provide a one step transfer in which a caregiver may simply press hold once to transfer a patient from one sensed area to another. In addition, the caregiver can simply actuate a single input with only a momentary press to allow suspension of monitoring for a shorter duration (hold) or a longer press to allow suspension of monitoring for a longer duration (extended hold).

The present invention provides a wearable device, comprising: a power source; a position sensor electrically connected to the power source, for sensing a position of a wearer of the wearable device and generating a position signal; a signal transceiver electrically connected to the power source, for receiving the position signal, sending the position signal to a monitoring apparatus, and receiving an indication signal from the monitoring apparatus; and a body of the wearable device comprises a first part and a second part, wherein a relative position of a moveable end of the first part and a moveable end of the second part can switch between a first relative position and a second relative position.

This invention relates to system and a method for supervising a person in an area, the system comprising a mobile base (100), such as for example a wristband,attached to the person, the mobile base (100) comprising a first radio frequency tag (11) prepared for radio frequency triangulation or positioning for deciding a position of the mobile base (100) and for communicating health, safety and environment (HSE) related components, the system comprising a controller (400) in communication with the mobile base (100). Furthermore, the invention relates to a system and a method for activated communication between an object and a reader,comprising a first radio unit (11) attached to the object, the first radio unit being configured for communicating with the reader.

A wireless, proximity-based security system for securing or tracking a valuable object. The system includes a base station and a plurality of security fobs.
