An underwater observation apparatus includes an observation apparatus body, a weight structure, a coupling device, and a fusion cutting device. The observation apparatus body is configured to house at least a power source, a communication circuit for a communication device, and a signal processing device. The coupling device couples the observation apparatus body with the weight structure via a remote-controlled release structure capable of releasing the observation apparatus body from the weight structure. The underwater observation apparatus also includes a power feeding coil located inside of a glass sphere to generate magnetic flux, and a power receiving coil located outside of the glass sphere. The power receiving coil generates an induced voltage when interlinked by the magnetic flux generated by the power feeding coil. The power receiving coil is configured to supply drive power to the fusion cutting device.

A communication system 100 is configurable to operate in either a transparent mode or a data streaming mode. In the transparent mode data is transferred to a data requesting component 112 from a data source 102 using a request-response protocol. In the data streaming mode a second data transfer component 106 is configured to obtain 606 data from the data source component via a third data link 104, and to transfer 608 the data to a first data transfer component 110 via a second data link 106, which has a relatively higher latency, without using the request-response protocol. The first data transfer component is configured to store 610 the transferred data and to transfer 614 the stored data to the data requesting component via the first data link upon receiving a request for the stored data from the data requesting component.

Embodiments described herein provide a system, apparatus and methods to enable a diver to communicate more clearly with other divers or locations Embodiments process the speech to add clarity, or otherwise convert speech into an outputted form that is more intelligible e.g. so as to simulate the diver's unhindered speech. Embodiments provide hardware and software for receiving and recognizing hindered speech of a diver (e.g., speech hindered by a mouthpiece) and then augmenting the speech with generated output sounds corresponding to the intended speech sound or generating or replacing at least some of the diver's speech with synthesized words. The output sounds may be in the speaker's own voice or a synthesized voice. Embodiments may be configured to add clarity to and/or augment speech that is hindered by the wearing of a mouthpiece from a snorkel, SCUBA or other diving apparatus.

The Adaptable Pulse Position Modulation (APPM) optical communication system and process facilitate wireless communications through turbid mediums including, but not limited to, smoke, airborne dust, mist, fog, clouds, water, seawater and water-to-air (air-to-water) interfaces by controlling the signal gain at the optical detector and controlling of the signal encoding to allow high data rate operation when the signal to noise ratio is high. The system also supports signal encoding redundancy to maintain good connectivity at the cost of the communication channel data rate as the signal to noise degrades.

Methods and apparatus for air to underwater communications. In one example, an optical transceiver configurable between two operational modes includes a laser assembly configured to transmit a modulated laser beam when in a first mode of the two operational modes and to transmit an unmodulated beam when in a second mode of the two operational modes, an optical receiver configured to receiver reflections of the unmodulated laser beam from a surface of a body of water and to output measurement data based on the reflections of the unmodulated laser beam, and a controller configured to determine surface conditions of the surface of the body of water based on the measurement data, to adjust at least one property of the modulated laser beam based on the surface conditions, and to operably switch the laser assembly between the first and second modes.

An aquatic environment audio system for communication of wireless audio signals between a smartwatch and headphones worn by a user includes one or more wireless repeaters. Each of the one or more wireless repeaters includes a waterproof housing, an attachment mechanism for attaching the waterproof housing to the user between the smartwatch and the headphones. Each of the one or more wireless repeaters further includes a first antenna for receiving wireless signals from the smartwatch, repeater circuitry coupled with the first antenna for processing the wireless signals received from the smartwatch, and a second antenna coupled with the wireless repeater circuitry for transmitting the processed wireless signals to the headphones. One or more of the first antenna, repeater circuitry, and second antenna are contained in the waterproof housing.
