  • Patent number: 10503264
    Abstract: Systems and methods for radial gesture navigation are provided. In example embodiments, user input data is received from a user device. The user input data indicates a continuous physical user interaction associated with a display screen of the user device. An initial point and a current point are detected from the user input data. A radius distance for a circle that includes the current point and is centered about the initial point is determined. An action is selected from among multiple actions based on the radius distance being within a particular range among successive ranges along a straight line that starts at the initial point and extends through the circle. Each range among the successive ranges corresponds to a particular action among the multiple actions. The selected action is performed in response to detecting a completion of the continuous physical user interaction.

  • Patent number: 10448292
    Abstract: A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.
