Systems, methods, and devices for locating items, people, and/or animals are provided. In accordance with some embodiments, locator devices for locating a target device are provided, the locator devices comprising: a first transceiver configured to communicate with a second transceiver in the target device; a Global Navigation Satellite System (GNSS) receiver configured to receive data from a plurality of satellites for calculating a location; a visual indicator; and a hardware processor that: receives signals from the first transceiver; calculates an estimated distance between the locator device and a target device based on the signals; controls whether the GNSS receiver is powered on or off based on the estimated distance; and causes the visual indicator indicate an estimated direction to the target device from the locator device.

Systems and methods are provided for machine learning based monitoring. Image data from a camera is received. On the hardware accelerator, a person detection model based on the image data is invoked. The person detection model outputs first classification result. Based on the first classification result, a person is detected. Second image data is received from the camera. In response to detecting the person, a fall detection model is invoked on the hardware accelerator based on the second image data. The fall detection model outputs a second classification result. A potential fall based on the second classification result is detected. An alert is provided in response to detecting the potential fall.

Disclosed herein is a method for facilitating supervision of individuals based on geofencing. Accordingly, the method may include receiving, using a communication device, a parameter from a supervisor device associated with a supervisor and a geographical location from the supervisor device. Further, the method may include analyzing, using a processing device, the geographical location based on a security parameter and generating a geofence corresponding to a geographical area based on the analyzing. Further, the method may include receiving, using the communication device, supervisee data associated with a supervisee from a supervisee device, including supervisee emergency input or nearby audio and video sensor data. Further, the method may include analyzing, using the processing device, the supervisee data based on the geofence and generating a supervision notification based on the analyzing of the supervisee data. Further, the method may include transmitting, using the communication device, the supervision notification to the supervisor device.

Disclosed are a safety service system and a method thereof. The safety service system comprises: a collection unit for collecting position information and image information related to a protected person who is registered by a protector; and a service providing unit for providing the position information and the image information to one or both of the protector and a security company upon detection of a signal that the protected person is in danger.

Various embodiments of the present invention provide systems and method for identifying three-dimensional zone areas for use in relation to the monitoring of physical movement of a target monitor device.

An embodiment of a minder device includes a selector and a transceiver. The selector is configurable in one of multiple configurations each corresponding to a respective one of multiple responses. And the transceiver is configured to receive, from a host server via a cellular network, a message from a monitor device associated with the minder device, and to send, to the monitor device via a cellular network and the host server, the one of the responses corresponding to the one of the configurations in which the selector is configured. For example, such a device can be a less-expensive alternative to, and can allow more monitor control, than a smart phone. Furthermore, such a device can be suitable for tracking and locating children too young to have a smart phone, for tracking and locating pets, and for tracking and locating objects.

An “invisible” leash that wirelessly connects a pet device to a user device and provides signals to a pet device for controlling pet behavior is disclosed. The pet device can include one or more sensors and output devices to communicate instructions and control pet behavior.

Disclosed are a safety service system and a method thereof. The safety service system comprises: a collection unit for collecting position information and image information related to a protected person who is registered by a protector; and a service providing unit for providing the position information and the image information to one or both of the protector and a security company upon detection of a signal that the protected person is in danger.

An exemplary virtual boundary system determines a refined geolocation of a tracking device based on a positioning signal and a correction signal that are accessed from distinct signal sources. The virtual boundary system compares the refined geolocation of the tracking device and a geographic boundary. Then, based on the comparing of the refined geolocation and the geographic boundary, the virtual boundary system provides an alert indicative of the refined geolocation with respect to the geographic boundary. Corresponding methods and systems are also disclosed.

A method and system are described for automated child monitoring. The system comprises wearable sensor device wirelessly connected to a mobile device. The system comprises sensors configured to detect environmental factors and activities of a child. In one or more embodiments, the activities may be one or more of drinking, vaping, smoking, driving and presence of a threat for a child. The system may be configured to determine real-time location of a wearer as well as contextual information. The sensor device is communicably coupled to one or more mobile devices, additional wearable devices or fixed units. The mobile device is configured to control one or more operations of the inconspicuous wearable device.
