Abstract: An emergency locator apparatus includes a transceiver configured to periodically send and receive communications with a plurality of other emergency locator apparatus including a target emergency locator apparatus using an ad-hoc wireless local area network. A processor is operably coupled to the transceiver and configured to determine location information of the target emergency locator apparatus utilizing at least context information associated with the communications received from at least a subset of the plurality of other emergency locator apparatus over the ad-hoc wireless local area network. A display is configured to display the location information determined by the processor.

Abstract: The present invention relates to a wearable assembly, such as an article of clothing or a life-jacket, for providing a rescue function, such as buoyancy, the wearable assembly comprising:—a support structure which can be arranged round the body, being wearable as for instance an article of clothing or life-jacket,—a fluid holder such as a buoyancy provider able to at least temporarily hold a fluid, preferably a gas, with a density lower than water,—a gas generator comprising a precursor for generating gas for the purpose of generating a gas substantially at a temperature which does not damage the human body or the human skin, preferably a corresponding ambient temperature.
