Abstract: The present invention is directed to polymers comprising glycolipids and methods for producing and using the same. In particular, the polymers of the invention comprise a polymer backbone and a plurality of glycolipid side chains. The glycolipid moieties present in polymers of the invention are metal ion complexing agents. As such, polymers described herein can be used for the remediation of aqueous solutions to remove metal ions.

Abstract: Embodiments of display control based on dynamic user interactions generally include capturing a plurality of temporally sequential images of the user, or a body part or other control object manipulated by the user, and computationally analyzing the images to recognize a gesture performed by the user. In some embodiments, the gesture is identified as an engagement gesture, and compared with reference gestures from a library of reference gestures. In some embodiments, a degree of completion of the recognized engagement gesture is determined, and the display contents are modified in accordance therewith. In some embodiments, a dominant gesture is computationally determined from among a plurality of user gestures, and an action displayed on the device is based on the dominant gesture.

Abstract: The present disclosure involves enabling a parent and child account relationship. One example method includes identifying a child account associated with a parent account, the parent account including a monetary amount, the child account being different than the parent account; identifying a communication associated with the child account; transferring at least a portion of the monetary amount from the parent account to the child account after identifying the communication associated with the child account; and debiting the portion of the monetary amount in the child account for charges associated with the communication.
