This invention discloses an inflator mechanism for rafts and life vests that performs a multitude of functions required for rescue and underwater deployment of personnel and devices. The inner cylinder in this disclosure is actuated by a plethora of inputs, manual, automatic selectable pressure sensing, or dualled hydrostatic sensors which can each be safely selected by function selection. Since the inflator uses spring discs to drive a penetrator which mechanically punctures a membrane of an inflation gas source and actuated by an electronically controlled solenoid, dissolvable elements, conductivity switches and preset check valve actuators are eliminated increasing the safety and reliability of the actuator. Electronic control further permits user enabling of inflation depth actuation and the multiple water sensors prevent failure of actuation due to splashes and humidity effects on sensors. The actuator mechanism is self cocking, indicates proper installation of gas source enables use of several gas source cylinders and is multiply reusable.

A safety device and a method of assisting a user using the safety device. The safety device has a wearable component worn by a user or portable component able to be carried by the user, one or more sensors configured to measure the environment and/or biological attributes of a user, and a controller in communication with the one or more sensors. The controller is configured to issue a notification upon determining a predetermined condition from the one or more sensors. The issuance of the notification preferably calls for assistance and/or activates an assistance device to assist the user.

A safety, rescue, and recovery device that compressively secures to a limb of a user when inflated. The device can be easily adjusted to be negatively buoyant, neutrally buoyant, or positively buoyant before inflation depending on whether the application is safety, rescue, or recovery. The device may also be integrated into an article of clothing for certain applications. An elongated handle is attached to the device to provide a sliding attachment point for a rescue rope that automatically reduces torque applied to the limb of the user. Consequently, a rescue force applied to the rescue rope can act at a variety of angles along an arc relative to the device.

An inflation device for an inflatable article comprises a housing for supporting a container of pressurized fluid and for supporting piercing means which is displaceable from a retracted position to penetrate the container and allow release of pressurized fluid, said container being contained within a protected casing which is secured non-releasably to the housing thereby to prevent removal of the pressurized container.
