Abstract: Magnetic locking mechanisms, linear movement generators, and holders are disclosed. According to an aspect, a magnetic locking mechanism includes a first component defining a first recess. The magnetic locking mechanism also includes a second component defining a second recess. Further, the magnetic locking mechanism includes a third component being attached to a first magnet and capable of being positioned in a first position such that the third component is partially within the first and second recesses for holding the first and second components together in at least one direction. Further, the third component is capable of being positioned in a second position such that the third component is outside of the first recess.

Abstract: Systems and methods for notifying a user of a user entry that matches security information and for hiding display of a user entry that matches security information are disclosed. According to an aspect, a method includes receiving user text input. The method also includes determining whether the user text input matches a predetermined portion of security information. Further, the method includes presenting notification of the match via a user interface in response to determining that the user text input matches the predetermined portion of the security information.

Abstract: Systems and methods for interaction with objects to implement a retail function are disclosed. According to an aspect, a system may be implemented by a computing device and a wearable detection device. The detection device may obtain data associated with a user part and an object. For example, the detection device may be an image capture device, such as a camera, that captures one or more images of a retail item and interaction of a user's finger with the item. The computing device may implement a retail function manager operable to receive data associated with a user part and an object. For example, the detection device may communicate to the computing device image data representative of the interaction of the user's hand or finger with the retail item. Further, the retail function manager may implement a retail function based on the interaction of the user part and the object.
