In an apparatus including a personal monitoring device which includes a microphone, speaker, camera, memory or database, global positioning device, controller, and transmitter, the improvement including a wearable device configured to include at least one of more components of the personal monitoring device on, with, or within, the wearable device, and a smoke detector, the fire detector, or the carbon monoxide (CO) detector. The microphone, speaker, or camera is located on an exterior of the wearable device. The smoke detector, fire detector, or carbon monoxide (CO) detector, is located on an exterior of the wearable device. The smoke detector, fire detector, or carbon monoxide (CO) detector, detects a presence of smoke, a fire, or a presence of carbon monoxide, and the speaker emits an alarm, a siren blare, or an audible and verbal message. The transmitter transmits a message to a computer or communication device.

The invention relates to a method for monitoring a child (2B) implemented by a child monitoring system (50), comprising an electronic control unit (510) and a motion detection module (520), comprising the following steps of: activating a motion detection module (520) and a first timer expiring at the end of a first predetermined duration; the electronic control unit (510) sending a warning message if the motion detection module (520) detects a movement of the child (2B), with said warning message being sent via the antenna module (10) to the communication device (2A-1) of the user (2A); reactivating the presence detection system (40) when said first timer has expired if no movement of the child (2B) is detected by the motion detection module (50) during the first predetermined duration.

Systems and methods are provided herein for detecting a child in a vehicle and then notifying a user and/or emergency service about the detected child. This may be accomplished by processing channel state information (CSI) and audio information related to the inside of a vehicle. The CSI may be generated using radio frequency (RF) sensors placed throughout the vehicle and the audio information may be generated using microphones placed throughout the vehicle. The system may detect a child within the vehicle using both the CSI and the audio information. The system may then transmit a notification to one or more devices based on detecting the child within the vehicle.

Systems and methods of tracking objects, including a sensor configured to detect data related to one or more attributes of the object, a tracking device attachable to the object to transmit data detected by the sensor, a software application modifiable by a user to receive transmitted data from the tracking device according to a frequency of data transmissions selected by the user, including firmware within a chip on the tracking device configured to determine a frequency of data transmissions from the tracking device to the software application based on instructions related to characteristics of transmitted data, wherein the instructions are modifiable by the user based on the characteristics of transmitted data.

In an apparatus including: a monitoring device including: a microphone, speaker, camera, memory or database which stores information regarding a travel schedule/itinerary, global positioning device which determines a position or location of the monitoring device, controller which automatically and continuously monitors a location of the apparatus or monitoring device and compares the location with the travel schedule/itinerary, and transmitter, the improvement including the apparatus further including a wearable device, wherein the monitoring device is integrated with or within the wearable device and the microphone, speaker, or camera, is located or situated on the wearable device; a electrically controlled connector for connecting ends of the wearable device; and a smoke, fire, or carbon monoxide, detector which detects a presence of smoke, fire, or carbon monoxide. The speaker emits an alarm, siren blare, or audible and verbal, message. The transmitter transmits the message to a computer or device.
