The present invention relates to water goggles, and particularly relates to water goggles having an excellent waterproofing effect, including a rim, a lens sealedly arranged on the rim, an elastic waterproofing ring sealedly arranged on an inside edge of the rim, and a head band whereof two ends are separately connected to the elastic waterproofing ring. The flexible waterproofing ring includes a first connection part connected to the rim, a support part connected to the first connection part, a left-eye contact part connected to the support part and pressed against the rim of a person's left eye, and a right-eye contact part connected to the support part and pressed against the rim of a person's right eye. The left side of the head band is connected to the left-eye contact part, and the right side of the head band is connected to the right-eye contact part.

A system and method of measuring bioelectric signals generated by an individual, inclusive of humans or other living organisms, comprises a plurality of sensors, at least one of the plurality of sensors being constituted by a capacitive-type sensor. Sensor has an associated insulated layer of material preventing the conduction of direct current between an electrode and individual, wherein a bioelectric signal of individual can be measured underwater.

An underwater mask includes a frame, a transparent part, a seal part mounted on the frame, and a snorkel. The seal part has a partition wall forming an upper and a lower chamber, the lower chamber receiving nose and mouth of the user. The two chambers communicate through a passage in the partition wall and a one-way valve so that air can pass only from the upper chamber to the lower chamber. The snorkel has first and second channels through which the upper and respectively lower chamber communicate with the outside. A connection end between snorkel and mask is fastened at an opening of the seal part to put the first channel of the snorkel in communication with the upper chamber of the mask, and further has a side inlet for a corresponding exhaust tube that puts the lower chamber in communication with the second channel of the snorkel.

Systems and methods for configurable dive masks in accordance with embodiments of the invention are illustrated. In one embodiment, a configurable dive mask including a dive mask frame, at least one lens located within the dive mask frame, a display device viewable through the at least one lens, a processor, a dive device data circuit that obtains dive device data from a set of sensor devices, a configuration interface circuit that communicates with configuration devices to obtain configuration data when the configuration interface is above water; and memory storing configuration data and dive device data, wherein the processor receives configuration data via the configuration interface, receives dive device data via the dive device interface, determines a portion of the dive device data to display based upon the configuration data, and displays dive device data in accordance with configuration data.
