The present disclosure relates to the field of wearable safety device. More particularly, it relates to an automatic wearable device for safe landing from an elevation.
BACKGROUND
[0002] Background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed disclosure, or that any publication specifically or implicitly referenced is prior art. [0003] Maintenance workers working in high rise buildings are always at risk of a fall from a height. In most cases such a fall involves severe injuries which can be life threatening. Conventional wooden platforms and platforms suspended by rope support are not reliable structures and can fail any time. [0004] Therefore there is need of a safety device that can ensure that a user can land safely on the ground in the event of a fall. Existing literature discloses a life-saving jacket coupled to a parachute which can be deployed manually during a fall and eventually help the user to land safely. Other literatures describe a set of airbags or inflatable parasails coupled to a suit that can be worn by the user and inflated for emergency evacuation from a high rise building. In another literature, an air filled suit is disclosed that can reduce air friction and mitigate impact force on hitting the ground. In all of these cases the safety suits need to be activated or prepared manually before jumping off an elevation and do not disclose a solution to accidental falling.
[0005] Hence, there is need in the art to develop an automatic wearable safety device that can be configured to activate a parachute automatically by receiving a set of input signals from a set of sensors coupled to the suit worn by the user. The proposed automatic wearable safety device can be used even when the user is unconscious or unfit to deploy the parachute or falls accidentally.
