PERSONAL SAFETY DEVICE AND ASSOCIATED ACCESSORIES

原文（中国語）

A personal safety device is disclosed. The personal safety device comprises an inner core and an outer layer disposed on the inner core. The personal safety device is selectively transformable between a rigid first state and a flexible second state. The inner core and/or the outer layer may be produced from a material or combination of materials, which results in the personal safety device having a desired buoyancy rating. A void/cavity may be formed in the inner core, the outer layer, and/or between the inner core and the outer layer, to contain air or another gaseous material, which results in the personal safety device having the desired buoyancy rating. An accessory device may be coupled to the personal safety device for added benefits and features.
