Disclosed herein are systems and methods for providing VR/MR experiences to users in water through a headset and at least one special-effects device. During a VR/MR experience, a controller may send commands to a special-effects device at particular times to cause the special-effects device to create effects in synchronism with the visual portion of the VR/MR experience. A headset application that provides the visual portion of the VR/MR experience may communicate with the controller before the experience begins to establish the identity of the experience and the start time. The VR/MR experience may be selected by reading a storage medium (e.g., a near-field communication (NFC) card) that identifies the experience and/or the controller. Some information on the storage medium may be included in a metadata file transferred to the application. The application may send information read from the storage medium to the controller via an over-the-air network.

A wearable safety system for either diving, harsh or anoxic environments, or for individuals at high risk for respiratory and/or cardiac failure is disclosed. The wearable safety system includes biometric monitoring and provides cardiac and/or respiratory support in the event that the wearer experiences cardiac and/or respiratory failure. There are different configurations of the wearable safety system designed to work with different use cases, and to provide different levels of protection. In the case of diving, the wearable safety system additionally utilizes data collected by the dive computer to advise a rescue diver as to the best course of action in managing an unconscious diver's ascent and can also inflate the diver's buoyancy control device (BCD) or onboard personal flotation device.

Described are various embodiments of a system and method for adaptive user experience cycle profiling under anomalous environmental respiratory conditions, such as in hyperbaric or hypobaric environments. In one embodiment, the system comprises an environmental sensor operable to monitor a respiratory environment parameter representative of the anomalous environmental respiratory condition that defines the experience cycle; and a physiological sensor operable to concurrently monitor a physiological parameter representative of the user's cumulative physiological response to the anomalous environmental respiratory condition over time during the experience cycle.

The present invention relates to a waterproof device for diving including a mobile terminal and an openable and closable waterproof housing for diving adapted to detachably mount the mobile terminal thereonto, wherein the mobile terminal includes an I/O module for displaying at least one of an information pop-up and a functional mode, a first sensor part for detecting internal pressure of the waterproof housing for diving, and a control unit for determining whether the waterproof housing for diving is normally fastened using the detected internal pressure.

The present disclosure generally relates to underwater user interfaces. In some embodiments, a method includes at an electronic device with a display and one or more input devices, receiving a first request to display a user interface for accessing a first function of the electronic device. In response to receiving the first request, and in accordance with a determination that the electronic device is under water, the method includes displaying a first user interface for accessing the first function. In response to receiving the first request, and in accordance with a determination that the electronic device is not under water, the method also includes displaying a second user interface for accessing the first function.

According to an example aspect of the present invention, there is provided an apparatus comprising memory configured to store a dive log, at least one processing core configured to receive the dive log from a dive computer, the dive log comprising information concerning a dive, the received dive log not including a location where the dive took place, obtain a geographic location of the apparatus, and add the location where the dive took place to the dive log based at least in part on the geographic location, and/or provide the dive log and the geographic location of the apparatus to a server.

The present invention refers to a device for detecting the pressure of compressed gas cylinders in breathing apparatuses for scuba diving which can be powered by means of a battery, provided with a pressure sensor. The device allows the housing of sensors with sufficiently large dimensions, guaranteeing precise gas cylinder pressure readings. Furthermore, the elements that guarantee the watertight seal of the device can be replaced in a practical effective manner.

Described are various embodiments of a self-monitoring oxygenation system and method. In one embodiment, a system is provided for monitoring for abnormal blood oxygenation levels. The system comprises: an optical spectroscopy probe for acquiring blood oxygenation data representative of deoxyhemoglobin levels over time; and a digital data processor operatively connected to said probe and programmed to: monitor relative variations in said deoxyhemoglobin levels to output a signal representative of a higher health risk rating of hyperoxia.

The present invention relates to instrumentation for underwater use powered by means of a battery and provided with a pressure sensor capable of periodically detecting pressure values inside the main body of the instrumentation.

The present invention also relates to a method for detecting possible pressure drops inside the main body of the instrumentation over time.

The instrumentation of the present invention enables carrying out efficient and inexpensive self-diagnosis of the pressure inside the body of the device, every time the battery is changed or also during manufacture of the instrument.

Equipment for underwater use with battery compartment cover provided with bayonet type connection system for fastening and unfastening the cover to/from the body of the equipment.
