An apparatus configured for use with a first power cord, a second power cord and safety glasses including a first wireless communication device. The apparatus includes at least one line conductor, an electrical isolation device configured to prevent current flow in the at least one line conductor, a second wireless communication device configured to wirelessly couple to the first wireless communication device and a body housing the electrical isolation device and the second wireless communication device. The body includes a collar configured to move in a direction parallel to the longitudinal axis while coupled to the body. The collar includes an interior wall that defines a hollow region sized and configured to receive at least a portion of the body therein, the collar configured to secure to one of the female electrical socket and the male electrical plug with the respective one of first power cord and the second power cord electrically coupled to the distal end of the body and the collar at least partially extended from the body in a direction of the distal end. The electrical isolation device is configured to allow current flow in the at least one line conductor when the information provided by the wireless signal indicates that the safety glasses are being worn by the user.

An electronic spectacle frame including: a face element including a housing for at least partially receiving a lens; and at least one electronic component. The face element includes at least one recess for receiving the at least one electronic component.

A customizable eyeglass system for use in any remote situation, and which is ideal for use in third-world countries or areas where electrical power and typical machinery for manufacturing eyeglasses is lacking. The system includes a frame with receivers for the temples to connect into and lock into place. A pair of customizable lenses is connected to the front of the frame. The lenses can be rotated to dial in the correct prescription for the patient and then locked into place as well. Thus, the invention corrects near and distance vision while also correcting astigmatism. If adjustments need to be made, the patient can easily unlock the lenses, rotate them to a proper orientation for proper sight, and then lock the lenses into place again. The replacement lenses can be used with optical enhancement scopes such as telescopes, firearm scopes, and binoculars.

A head-mounted wearable device incorporates a transducer into a nosepiece. Vibrations from the user's speech are transferred through the bridge of the nose and are detected by the transducer to produce an audio signal. In one implementation, a nose plate with a pair of attached nosepieces is mounted to a transducer, such as an accelerometer. The nose plate may be affixed to a front frame of the head-mounted wearable device using a motion limiter mechanism.

Methods and devices for wired charging and communication with a wearable device are described. In one embodiment, a symmetrical contact interface comprises a first contact pad and a second contact pad, and particular wired circuitry is coupled to the first and second contact pads to enable charging as well as receive and transmit communications via the contact pads as part of various device states.

A head mounted device intended to be worn by a wearer comprising: a battery, and a flexible wireless power system receiver connected to the battery through at least one electrical connection mean, the flexible wireless power system receiver being arranged to receive an electromagnetic field so as to allow charging of the battery through the electrical connection means.

A pair of electronic eyeglasses includes an eyeglasses frame and an eyeglasses lens mounted within the eyeglasses frame. At least one femtoprojector is embedded within the eyeglasses lens. The femtoprojector includes an image source and an optical system that projects an image from the image source onto the retina of the wearer. The femtoprojector is small enough that is does not significantly interfere with the wearer's view through the eyeglasses lens.

The invention relates to a glasses frame having a main frame provided with two openings for respectively receiving two lenses, at least one opening having an inner peripheral edge for cooperating with an outer peripheral edge of a lens, the glasses frame having at least one functional member. According to the invention, the peripheral inner edge of said opening of said frame has at least one recess in which said functional member is mounted, said functional member being designed so as to be locked in position by said lens when it is mounted in said opening.
