Spinnable frames for spectacles are provided. A spinnable frame allows a user to hold a distal end of one of the temples and freely spin the remainder of the spectacles around that end of the temple. A spin joint is provided in at least one of the temples that allows this spinning action. The spin joint may span an interface between the distal end of the temple and a proximal end of the temple, the proximal end being coupled to a front portion of the frame at a hinge interface. In this way, the temple arm is allowed to fold against the front portion for compact storage, as with conventional eyeglass frames, while facilitating spinning of the spectacles in a way that avoids excess forces on the hinge interface and/or other portions of the frame or lenses mounted therein.

Systems and methods herein describe an actuator control system for intelligent actuated temple attachments on a pair of eyeglasses. The actuator control system receives current measurements corresponding to a length of eyeglass temple attachments on a pair of eyeglasses, and generates predicted measurements for the temple attachments using a machine learning model. The actuator control system transmits the predicted measurements to pneumatic actuators coupled to the eyeglass temple attachments and determines pressure measurements corresponding to a pressure of eyeglass temples against a user of the pair of eyeglasses. Based on the pressure measurements, the actuator control system generates adjusted measurements for the temple attachments and transmits the adjusted measurements to the pneumatic actuators coupled to the eyeglass temple attachments.

Systems and methods herein describe an actuator control system for controlling intelligent actuated temple tips of a pair of eyeglasses. The actuator control system receives a set of measurements corresponding to a length of eyeglass temple tips on a pair of eyeglasses, receives, from a user of the pair of eyeglasses, user feedback corresponding to a position of the eyeglass temple tips, generating a predicted set of measurements for the length of the eyeglass temple tips using a machine learning model, and transmits the predicted set of measurements to pneumatic actuators coupled to the eyeglass temple tips.

A temple unit for an eyewear includes two temples each including pivotally connected front and rear segments. The front and rear segments respectively include adjacent rear and front ends. One of the front and rear ends is formed with a protruding portion, and the other one of the front and rear ends is formed with a recess portion. The protruding portion has at least three non-coplanar first flat surfaces defining two convex corner sections. Any two adjacent ones of the first flat surfaces are connected to each other to define one of the convex corner sections. The recess portion has at least two non-coplanar second flat surfaces connected to each other to define a concave corner section engaging a selected one of the convex corner sections so as to position the rear segment relative to the front segment.

Systems and methods for adjusting a level of force exerted by the temple arm portions of a frame of a head mounted wearable device are provided. Hinge mechanisms that provide for the rotatable coupling of a temple arm portion to a rim portion of a frame of the head mounted wearable device, or glasses, may include a rotation mechanism that facilitates rotation of the temple arm portion relative to the rim portion, and a biasing mechanism that can be adjusted to apply a desired level of lateral force to a head of a user wearing the glasses. The hinge mechanisms may allow for adjustments to biasing rates and/or pre-load levels and/or amounts of temple arm portion rotation prior to engagement to adjust the applied force to desired levels and maintain user comfort.
