Abstract: Embodiments described herein include methods and apparatus for dynamically selecting antenna settings for reception of wireless signals in multiple radio frequency band by wireless devices. A wireless device includes at least two SIM/eSIM profiles that each use different radio frequency bands and dynamically selects an antenna tuner setting based on requirements of one or more applications in use and key radio frequency performance indicators. In some embodiments, the antenna hardware tuner setting is selected to improve paging reception for a secondary SIM/eSIM from a second cellular wireless network when applications communicating using a first SIM/eSIM via a first cellular wireless network can accommodate performance degradation for a period of time.

Abstract: Maintaining the integrity of a virtual currency and by reducing the impact of hacking and otherwise fraudulent manipulation of an electronic game, and thereby encouraging end users to use freemium model software, may include managing the distribution of virtual currency giveaways. In some embodiments, virtual currency may be distributed in a secure manner by a server. In addition, user interest also may be maintained by providing unique features such as a double-up mini-game that allows a user to wager an amount won on a winning slot reel spin. The user may select one of two options and either win or lose the amount wagered. In some embodiments, a user may wager more or less virtual currency by applying a multiplier to the amount won on the winning slot reel spin. In addition, user interest may be maintained by integrating story elements into the one or more themed slot games.

Abstract: A method for producing an aliphatic polyester resin including a melt polymerization step and a subsequent solid phase polymerization step, using a sulfonic acid group-containing compound as a catalyst, wherein the addition amount of the sulfonic acid group-containing compound during melt polymerization is 300 to 3000 ppm with respect to a raw material monomer calculated as sulfur atoms, the content of the sulfonic acid group-containing compound during melt polymerization is 300 to 3000 ppm with respect to a produced polymer calculated as sulfer atoms, and a residual rate of the sulfonic acid group-containing compound after solid phase at polymerization is more than 50.
