Abstract: An electric-powered personal transport vehicle with a board to support a weight of a user and one or more wheels driven by one or more electric motors is discussed. The electric motors are powered by one or more batteries. A throttle has a thumb wheel speed controller on a handlebar. The thumb wheel speed controller has a horizontal manipulation between accelerate, neutral, and brake input positions such that pressing the thumbwheel speed controller in a vertical direction will not result in an unintentional acceleration or braking.

Abstract: 3D glasses including features for an enhanced viewing experience with lower production and operating costs for theaters. Keyed lenses and removable temples facilitate assembly and field repairs. Specific angles of lens placement and the provision of specific anti-reflective areas on the frames enhance the quality of the optical path content being viewed. RFID and radio chips increase accountability and collection of use statistics. Smooth areas enhance cleaning and lower the time and material costs for between use cleanings.

Abstract: Eyewear includes a set of lenses, a frame, and a pair of arms. A primary attachment feature facilitates attachment of the arms to the frames. A secondary attachment feature facilitates attachment of the arms to the frames in case the primary attachment feature becomes partially or wholly dysfunctional. A concealment feature at least partially conceals the secondary attachment feature. The concealment feature is detachable to permit use of the secondary attachment feature. In an example embodiment, the concealment feature is formed as an integral breakaway component of the arms.

Abstract: A novel pair of eyewear includes a frame, one or more optically active eyepieces, a first temple piece and a second temple piece. The first and second temple pieces each include an adjustment mechanism for adjusting the length and angle of the first and second temple pieces. In a particular embodiment, the first and second temple pieces each include a locking mechanism for fixing the length and angle of the first and second temple pieces with respect to the frame.

Abstract: A 3D projection and viewing system comprising viewing glasses having a frame including a receptacle mechanism on an eyewear frame, the receptacle mechanism configured to receive a corresponding portion attached to a temple part of eyeglasses comprising the eyewear frame. The corresponding portion may be, for example, an insertable snap device that fits into the receptacle mechanism and includes a barb or other latch mechanism that “snaps” into place.
