Abstract: A repositionable frame system includes a repositionable wall mount configured for being repositionably secured to a support surface. The repositionable wall mount includes a first magnetic element. The system further includes a frame having a rear face that includes a second magnetic element that is magnetically attracted to the first magnetic element resulting in a magnetic coupling between the frame and the repositionable wall mount.

Abstract: A lifting aid for an attic ladder includes a track system having a plurality of attachment means configured to secure about a corresponding number of attic ladder rungs. A hand winch is secured to the base of the device and is in mechanical operation with a tray which runs up and down the attic ladder to which the track system is secured.

Abstract: A markerless augmented reality (AR) can track 2D feature points among video frames, generate 2D point clouds and 3D point clouds based thereon, and match a 3D model against 3D point cloud to obtain proper positional information of the model with respect to a frame. The AR system can use the 3D model with the obtained positional information to render and project AR content to a user's view. Additionally, the AR system can maintain associations between frames and 3D model positional information for search and retrieval.

Abstract: Teethers are configured with a base, a biting structure that extends distally from the base, and one or more handles that extend proximally from the base. The base has a hollow interior with both a proximal opening and a distal opening. The biting structure is also hollow and includes a proximal opening such that the biting structure has a proximally-facing concave interior. As a result of this design, a baby may use the teether by either grasping the one or more handles or by inserting his or her fingers through the base and into the concave interior of the biting structure. With the baby's fingers inserted into the concave interior of the biting structure, the baby can satisfy the desire to insert his or her fingers into the mouth while also biting on the teether.
