Smart personal safety device, system, and method. A personal safety device for dispensing a chemical irritant includes a body for receiving a product cannister, a first actuation mechanism for dispensing product from a product cannister received within the body, and a wireless data communication module coupled to the body for wirelessly transmitting a triggering signal to a remote receiver when the first actuation mechanism is actuated to dispense product from a product cannister received within the body. The wireless data communication module is separable from the body. The wireless data communication module includes a second actuation mechanism configured to actuate the data communication module when the wireless data communication module is separated from the body. The personal safety device can be incorporated into a personal safety system that can send an emergency alert signal to third parties when the chemical irritant is dispensed.

Compact self-defense devices and alert systems are disclosed. An example compact self-defense device includes a housing defining a chamber configured to house a cartridge of an inflammatory agent. The compact self-defense device includes a spray nozzle including a button and at least partially housed in the housing. The spray nozzle is configured to receive the cartridge in the housing. The spray nozzle is configured to spray the inflammatory agent when the button is engaged. The compact self-defense device includes a sensor housed in the chamber and configured to detect when the spray nozzle is spraying the inflammatory agent. The compact self-defense device includes a communication module housed in the chamber and configured to transmit a signal for alerting one or more preselected emergency contacts in response to the sensor detecting that the spray nozzle is spraying the inflammatory agent.

The present disclosure pertains to the field of personal safety systems, and particularly to wearable electronic devices that detect distress through multi-modal sensing and autonomously initiate defensive, evidentiary, and emergency-communication actions. A personal safety device is disclosed that autonomously detects and responds to user distress. The device includes a deformable housing acting as an activation interface, a processing core executing a multi-modal threat-detection algorithm, and physiological, inertial, positional, and acoustic sensors. A location module, imaging and illumination units, and self-defence systems—including a controlled non-lethal electric-discharge unit and a forensic marking-fluid dispenser—are activated when a multi-condition threat rule is satisfied. The system computes a dynamic threat index from heart-rate variability, motion deviation, oxygen-saturation change, electrodermal activity, and distress-signature analysis, and transmits diagnostic and positional information to designated recipients. A cloud-based behavioural-learning platform updates user-specific thresholds to enhance detection accuracy without requiring deliberate user action.

Repellent spray dispensers and methods of their use. Such a repellent spray dispenser includes a case configured to enclose a canister containing a repellent, an exit orifice configured so that a stream of the repellent propelled from the canister exits the case through the exit orifice, an audible alarm, a first actuating member operable to cause the audible alarm to be generated simultaneously with the stream of the repellent being propelled through the exit orifice of the case, and a second actuating member operable to cause the audible alarm to be generated without causing the stream of the repellent to be propelled through the exit orifice of the case.

An emergency alert apparatus for providing stimuli such as alarms, lights, and data transmission to alert others to an emergency includes a garment which locks onto a user via a lock mechanism. An alert assembly is mounted to the garment and may include speakers, light emitters, data transmission electronics, and the like. An actuator is provided which triggers the alert assembly to exhibit stimuli intended to draw attention to the user. The alert assembly continues to exhibit the stimuli when the actuator is returned to an initial state and terminates the stimuli when the lock mechanism is unlocked.

There is described a method for identifying potential personal safety incidents of an individual (5), the method comprising the steps of receiving a sample data set comprising motion data and vital sign data from one or more sensors (14, 16, 18) associated with the individual, determining one or more motion features and one or more vital sign features, and determining whether the sample data set is indicative of a potential personal safety incident of the individual based on a model and at least one of the motion and vital sign features. The sensors can be provided by a fitness tracker and / or an activity tracker, such as a smartphone and / or a smart watch. The method can also include determining one or more responses such as alerting another party of the potential personal safety incident or triggering a deterrent mechanism.

In a linked notification system configured by communication-connecting at least one external device to a portable notification device, on receipt of a state signal indicating a state of the external device from the external device, the portable notification device refers to the notification control information in which a notification destination is associated with a notification condition defined by using a state of the external device, and determines whether the notification condition is satisfied or not on the basis of the state signal. When it is determined that the notification condition is satisfied, the portable notification device notifies the notification destination associated with the notification condition.

Systems and methods to provide a portable alarm, are disclosed herein. The system may include a top component that includes a connector, a first securing protrusion, and a second securing protrusion that extend out a bottom side of the top component; and a base component that includes a narrow cavity, a first notch, a second notch, and a battery-powered circuit board, the first securing protrusion, the second securing protrusion, and the connector engaging with or otherwise connecting with the first notch, the second notch, and the narrow cavity, respectively, to provide secure contact between the top component and the base component, the narrow cavity is linked to the battery-powered circuit board so that responsive to the connector being disengaged from the narrow cavity, an alarm is activated and responsive to the connector being engaged with the narrow cavity, the alarm is deactivated.
