A floatation attachment system may include a floatation attachment device configured to be attached to an object. The floatation attachment device may include a floatation material configured to provide buoyancy to the object it attaches and an attachment surface configured to directly attach the object. The floatation material may include a material that expands or generates gas upon contact with water. The system may include a dispenser such as a sheet of pre-cut floatation attachment devices or for manual cutting for customized shapes and sizes. In one instance, the system includes a tape roll dispenser for dispensing floatation attachment devices from a roll.

The present disclosure provides a loudspeaker device. The loudspeaker device may include an earphone core configured to transfer an electrical signal to a vibration signal; an auxiliary function module configured to receive an auxiliary signal and perform an auxiliary function; a first flexible circuit board configured to electrically connect to an audio signal wire and an auxiliary signal wire of an external control circuit, the audio signal wire and the auxiliary signal wire being electrically connected with the earphone core and the auxiliary function module, respectively through the first flexible circuit board; and a core housing configured to accommodate the earphone core, the auxiliary function module, and the first flexible circuit board. The wiring process inside the loudspeaker device provided in the present disclosure may be simplified, thereby further reducing a volume of the loudspeaker device.

Detachable wearable electronic eyeglasses and head mounted gear with a plurality of electronic functions and interchangeable electronic function, and a wearable computer with optimal weight distribution and stretchable arms.

A modular electronic communication system is disclosed with interchangeable components attachable on eyewear. A plurality of pre-existing eyewear models can each be retrofitted by attachment of one or more of such interchangeable components to that eyewear. Such components can be configured for custom attachment with a particular eyewear or such components can be configured for universal attachment with one or more different eyewear models. The communication system can be configured to produce an adjustable heads-up display for the wearer of the eyewear. The electronic communication system can comprise a plurality of interchangeable, electronically interconnected components, such as a first optical module, a first base module, a base link, a second base module, and/or a second optical module. In some embodiments, one or more or all of the components of the electronic communication system are integrally and permanently attached to an eyewear and are not interchangeable or modular.

Eyewear including an optical element, a controller, a support structure configured to support the optical element and the controller, light sources coupled to the controller and supported by the support structure, and a diffuser positioned adjacent to the light sources and supported by the support structure, the diffuser including microstructures that diffuse light emitted by the light sources in a radial anisotropic diffusion pattern or a prism-like diffusion pattern.

An electronic contact lens. In some embodiments, the electronic contact lens includes a radio antenna and radio receiver contained within the contact lens, the receiver comprising antenna impedance matching and in-phase and quadrature signal generation such that signals from the antenna are projected into in-phase and quadrature components before mixing with a local oscillator signal in the receiver. The electronic contact lens may further include electronic circuits contained within the contact lens, the electronic circuits receiving data from the radio receiver.

In one embodiment, an eyewear for a user includes an eyewear frame, electrical circuitry at least partially in the eyewear frame, and a touch sensitive input surface on the eyewear frame configured to provide an input to the electrical circuitry to perform a function via touching the touch sensitive input surface. In another embodiment, the eyewear includes a switch with at least two operational states. The operational states of the switch can be configured to be changed by sliding a finger across the touch sensitive input surface of the frame.

Methods, systems, and devices are disclosed for implementing switchable dispensing and/or delivery of scented substances. In one aspect, a device includes a cartridge structured to include one or more chambers containing one or more scented substances contained in a corresponding chamber, a housing structured to include a compartment to hold the cartridge, an opening to allow the scented sub stances to dispense to an outer environment from the device, and one or more transporting channels formed between the compartment and the opening, in which each of the one or more transporting channels is configured to accelerate a scented substance from the corresponding chamber to the opening, and an actuator switch arranged in a corresponding transporting channel and operable to move between an open position and a closed position based on an applied signal to selectively allow passage of the scented substance from the corresponding transporting path.

Eyewear including a multi-layered display having an adhesive bonding the layers together at an offset distance inward from an outer edge of the layers. The display has an image display layer, such as an optical waveguide in one example, and a pair of layers encompassing the image display layer and which may comprise optically transparent substrates, such as glass. A respective adhesive is positioned the offset distance inward from the outer edge of the display layer between the image display layer and each of the pair of layers to reduce stress in the display. Each of the adhesives may be a continuous bead such that there is no adhesive between the pair of layers and the image display layer at the outer edges. In one example, the offset distance may be at least double the thickness of the image display layer to reduce stress in the image display layer.

A first determination unit determines whether a movement of an eyelid or an eyebrow of a wearer has occurred, based on an electric signal measured by a first measurement electrode with a common electrode as a ground potential. A second determination unit determines whether a movement of a jaw of the wearer has occurred, based on an electric signal measured by a second measurement electrode with the common electrode as a ground potential. An output unit outputs a command due to operation of a spectacle frame by the wearer when the first determination unit determines that the movement of the eyelid or the eyebrow of the wearer has occurred and, at the same time, the second determination unit determines that the movement of the jaw of the wearer has occurred.
