The invention relates to an eyeglass joint for an eyeglass frame with a first joint part assigned to a rim of the eyeglass frame, and a second joint part assigned to an eyeglass temple of the eyeglass frame, wherein the joint parts are movably connected to each other by means of at least one spring element attached to both joint parts, wherein the spring element preferably has a closed annular shape and/or is rubber-elastic. Furthermore, the invention relates to a joint set, an eyeglass frame, an eyeglass frame set, and the use of a spring element.

A head-mounted wearable device (HMWD) may incorporate bone conduction speakers (BCS) to generate audio output that is perceptible to a wearer. During operation, vibrations of the BCS may produce sound in the surrounding air that is perceptible to bystanders. An active noise cancellation module monitors the output and generates cancellation audio that is out of phase with the sound leaked by the BCS. An air conduction speaker emits the cancellation audio, producing destructive acoustic interference to the leaked sound. As a result, the user of the HMWD is able to hear audio clearly while bystanders are not.

A head-mounted wearable device incorporates a channel inset into a front frame. A flexible printed circuit (FPC) is arranged within the channel and allows communication between a left side of the front frame to a right side. Using the FPC, electronics in a left temple attached to the front frame are connected to the electronics in a right temple attached to the front frame. A retention piece is used to maintain the FPC within the channel, provide protection from an external environment, and so forth. The retention piece may comprise an overmold of silicone plastic.

Spectacles including auricular devices are described. The spectacles include a structure having a front frame for supporting respective lenses, and a pair of arms articulated to the front frame on laterally opposite sides, each of the arms extending longitudinally between a first end that is articulated to the front frame and a second, opposite end, close to which an end arm portion can make contact with the head at the ear. Each arm extends from the second end into an arm portion that is made of flexible material and bears an element for supporting an auricular device, and the arm portion can move, on account of its flexibility, between an operating position in which the support element is worn at the ear to allow the auricular device to be positioned, and a non-operating position in which the support element is removably held on the end arm portion.

Spectacles are provided with sensors for detecting biometric data when worn and when in contact with the head of the user. The spectacles include a frame having a front mount for supporting respective lenses, a nose support device and a pair of arms articulated on the front mount on laterally opposite sides, each of the arms extending longitudinally between a first end and a second, opposite end, close to which an end portion of the arm can make contact with the head at the ear. Each arm extends from the second end to a section of the arm made of flexible material that can support an auricular sensor, and the section of the arm can move, on account of its flexibility, between an operative position and a non-operative position, in which the sensor supported by the section of the arm is removably retained on the end portion of the arm.

Smart glasses comprise a glasses frame. The smart glasses further comprise a pair of glasses legs connected to two lateral portions of the glasses frame respectively, each of the glasses legs having a first end and a second end, wherein the second end of each of the glasses legs bends inwardly to form a first arc portion. In addition, the smart glasses further comprise a pair of clamping members each disposed at one of the glasses legs, wherein each of the clamping members comprises an elastic clamping element, said elastic clamping element being disposed at the inner side of said second end, wherein said elastic clamping element having a free end that bends inwardly to form a second arc portion.

An eyewear retention device is disclosed that includes a length of resilient braided or monofilament line, terminating at each end in a tapered, rubberized retention tubing. One or more retractable spring loaded mechanisms have a locking mechanism for easy extraction and retraction back and forth by simply pulling on said line. The combination of the resilient line and the mechanisms produces a tensioned arc such that in addition to retaining eyeglasses around wearers head when in use when not in use with a simple pull on said line, the retention device forms a suspended arc over the wear's upper torso such that the device does not contact the wear's upper torso or their vestment when donned over a wear's eyes.

Wearable electronic devices, for example wearable camera systems, and methods for attaching electronic devices such as camera systems to eyewear or other wearable articles are described.

Glasses that are provided with biosensors for detecting signals and are in contact with the user's head are described, which glasses comprise a front frame (2) for supporting respective lenses (4), a pair of sides (6) articulated to the frame (2) on laterally opposing sides, and a nasal-bearing device (8), a pair of sensors (10a, 11a) being integrated in the nasal-bearing device (8) in order to make contact with the surface of the nose, a third sensor (12) being mounted in the centre of the nasal-bearing device (8) in order to make contact with the surface of the face in the zone of the bridge of the nose, and each of the sides (6) comprising a side body (6a) extending into an end side portion in which a particular sensor that makes contact with the head is integrated.

Glasses that are provided with biosensors for detecting signals and are in contact with the user's head are described, which glasses comprise a front frame (2) for supporting respective lenses (4), a pair of sides (6) articulated to the frame on laterally opposing sides, and a nasal-bearing device (8), each of the sides (6) extending in a longitudinal extension direction and comprising a side body (6a) extending into an end side portion (6b) in which a particular sensor (25) that makes contact with the head is integrated, and in which the end side portion (6b) comprises a pair of branches (26a, 26b), which extend from a common end (27), which is connected to the side body (6a), in the longitudinal extension direction of the side (6) in a manner spaced apart from one another, one (26a) of the branches being provided with an internal cavity (29) for housing a core (30) made of a conductive metal material and both the branches (26a, 26b) being made of a resiliently pliable and electrically conductive material.
