A recovery device can include a bladder, a canister, an opening mechanism, and a tether. The bladder can be disposable in an inflated configuration and an un-inflated configuration. The canister can contain a compressed fluid and be coupled with the bladder. The opening mechanism can be configured to selectively open the canister and direct the compressed fluid into the bladder. The tether can extend between a first end coupled to the bladder and a second end engageable with a vehicle. The bladder in the inflated configuration can define a volume of less than one-tenth of a cubic meter.

A lighthouse lantern comprising a power supply and a phosphor-containing emitter is disclosed. The lighthouse lantern includes a power supply; a laser diode configured for receiving power from the power supply and irradiating laser in one direction; a phosphor-containing emitter positioned on a traveling line of the laser, wherein the emitter is configured for receiving the laser and emitting light; and a pair of reflective structures disposed symmetrically with respect to the phosphor-containing emitter, wherein each reflective structure has a reflective surface inclined in a direction away from the phosphor-containing emitter, wherein the reflective surfaces of the reflective structures are symmetrical with each other with respect to the phosphor-containing emitter. In accordance with the present disclosure, the lighthouse lantern may generate high output with low input power and thus has improved power efficiency, may suppress frequent failures near sea or seawater, and may reduce production costs.

A system and method for managing information related to marine activities and selectively sharing such information is provided. The system is designed to collect environmental data and create buoy profiles that may be analyzed by users to scout environmental conditions that may be conducive to catching fish in certain geolocations. Buoy profiles are updated in real time by fisherman using the system. The system is also designed to collect information pertaining to a catch and create an activity profile that may be analyzed by users to scout optimal geolocations in which to catch fish. A user's activity profiles may be shared with other users or kept private depending on permission levels within the system. Additionally, the system is designed to alert users of dangerous weather conditions and optimal fishing geolocations based on the buoy profiles and environmental states created by the system.

The present disclosure discloses a system wherein coin-sized beacons can be attached to marine and other hazards such as buoys, shipwrecks, jetties and the like. The beacons can also be configured to a user's life jacket or other intimate item worn by divers or passengers. The beacon is equipped with an ability to emit sound/radio or light (Bluetooth or otherwise) waves that are detected by a user's receiving device hardware located aboard a vessel to alert the user of an approaching hazard. The signal can be configured to provide the location or distance and proximity to the vessel of the beacon and contact information of the beacon's registered owner. The beacon can continuously transmit these signals to alert oncoming vessels of the location of the beacon, or aid in the recovery of an overboard passenger or keep track of underwater divers. Further, the receiving device hardware can be adapted to a vessel's navigation system to automatically avoid marine hazards using the vessel's autopilot system.
