A wearable device is provided. A wearable device according to an exemplary embodiment of the present invention comprises: a body unit comprising at least one function module; a wearing unit that has a predetermined length and is connected to the body unit such that the body unit remains worn on the user's face; and at least one flexible battery embedded in the wearing unit so as to provide the body unit with power such that the function module can be driven.

A SWIM GOGGLES HEADWEAR AND COSTUME SYSTEM WITH A COSTUME SWIM MASK, HAVING A MASK ELEMENT ATTACHED TO AT LEAST ONE COSTUME ELEMENT, AND AT LEAST ONE INTEGRATED GOGGLES, EYEWEAR, AND/OR LENSES ELEMENT providing under water vision with a water-tight sealing portion or mechanism securing the eyepieces around the eye area of a user during use of the goggles and a material or fabric costume mask element conducive to being worn by a child or adult and to even help in aiding the process of learning to swim.

The present invention is to provide a head strap device which includes a head strap having a first set of connecting section, a second set of connecting section, and a central section, and an adjustment buckle for positioning and adjusting the head strap, characterized in that: the central section of the head strap is a curved surface that can be naturally approach engagement on a back of the head while worn to avoid the head strap sliding, in addition, an opening disposed within a body of the adjustment buckle, and a pins and a guide posts disposed with misaligned each other on the opening that can separate the overlapping head strap after assembled, so that there is no need to remove the swimming goggles when the head strap is worn and adjusted, to achieve the effect of easily use.

A waterproofed wearable displaying device with an augmented reality function. The wearable displaying device is in form of goggles. A waterproofer is attached in front of a lens of the goggle. A receiving space defined between the waterproofer and the lens is sealed. The wearable displaying device further includes an image capturing device and a display in the receiving space. When the user wears the wearable displaying device indoors or outdoors, the display faces to the user's eyes, and modules in the device can detect air pressure and humidity in the goggles, to maintain air pressure within the goggles at a slight vacuum compared to the air pressure outside.

An underwater mask includes a buckle with a strap that can be moved and adjusted in the up-down and lateral directions on a wearer's head. The buckle includes a base including a spring with a locking hook, a strap adjuster body turnably attached to the base and including a plurality of engaging teeth configured to sequentially engage with the locking hook according to the turn, a handling member held inside the body and operated from outside the body, and a stopper held by the body. The handling member includes a spring, sliding portion, and a pair of finger pads exposed outside the body by the spring. The stopper includes a sliding contact tapered protrusion that slides sliding against the pair of sliding portions to cause the stopper to swing toward a direction opposite to the strap adjuster body and release the pawl from the engaging teeth of the strap.

An accessory mount for goggles is disclosed which may be attached to the strap or straps of goggles worn on the face of a person. The accessory mount may include a body and a mounting structure. The body may include one or two slits through which the strap or straps of the goggles may be inserted. The body may also include a facial section contoured to fit a person's face, and the facial section may have a cushion configured to rest against the face. The mounting structure may be configured so that different types of accessories, such as a camera or flashlight, may be removably affixed to the mounting structure.

Systems and methods for lap timing and counting in athletic events are disclosed. The systems and methods do not require the athlete to wear a counter/timer, a transmitter, a reflector or another kind of marker. A portable computing device with a sensor, such as a tablet computer with a camera, is positioned in an appropriate location. Data from the sensor is transformed into a time series of data, and one or more learned statistics are calculated in real time as benchmark ambient conditions. The learned statistics are essentially continuously updated and data that indicates irrelevant volatility is excluded. A detection threshold is determined and essentially continuously updated based on the learned statistics, and lap completion is determined based on the threshold. Times, lap counts, and other data are displayed on the portable device in real time.

The present invention provides a strap for securing a garment/article (e.g. swimming goggles) to a wearer's/user's body. The strap comprises a first portion comprising a tensioner end including a tensioner having an attachment portion. The attachment portion is for attachment to the tensioner end. The strap further comprises a second portion having indicia provided along at least a part of its length. In use, the second portion passes through the tensioner and the tensioner frame defines a window in which at least one of the indicia on the second portion is visible.

A structure of a mask (1) is provided. The structure includes a frame (10), a viewing window assembly (20), and a waterproof skirt assembly (30). The face portion (32) of the waterproof skirt assembly has a circumferential contact area (33). The face portion has a first shape and is made of a material that includes a re-moldable material. When a user (U) puts on the mask through a fastening device (40), the face portion is adapted to be squeezed and deformed to be in a second shape by the user's face, whereby making the circumferential contact area be capable of further following the contour of the user's face; whereas when the user takes off the mask, the face portion remains in the second shape.

The invention relates to spectacles. Said spectacles comprise a spectacle lens having a liquid crystal cell (LC) the transmission (TR) of which can be switched between transmitting and blocking. Furthermore, the spectacles comprise an eye tracker (ET) which can detect the viewing direction of the eye. They further comprise at least one sensor (IL, IR) for measuring the brightness of the visible light incident on it, said sensor being arranged on the eye side of the spectacle lens and measuring the brightness entering through the at least one spectacle lens in a spatially resolved manner. The sensor can determine the brightness of the visible light incident on it from the viewing direction of the eye detected by the eye tracker. The spectacles also have a closed loop control system for controlling the transmission of the liquid crystal cell, a desired value for the brightness at the level of the eye being predetermined, and the closed loop system using the brightness measured by the sensor in the viewing direction of the eye as the actual value.
