Abstract: A hybrid airbag inflator includes a pyrotechnic booster gas generant disposed in a booster combustion chamber and a pyrotechnic main gas generant disposed in a main combustion chamber. The hybrid airbag inflator also includes an initiator and a pressurized gas. The pyrotechnic booster gas generant and the pyrotechnic main gas generant are the same pyrotechnic composition but take different physical forms. The initiator deploys into the booster combustion chamber to ignite the pyrotechnic booster gas generant which in turn ignites the pyrotechnic main gas generant. The pressurized gas is in fluid communication with both the booster combustion chamber and the main combustion chamber prior to deploying the initiator, such that the pyrotechnic booster gas generant in the booster combustion chamber is under pressure before the initiator deploys.

Abstract: A method of making Voice over Internet Protocol (VoIP) calls, legacy circuit calls, sending/receiving Short Message Service (SMS) over Long Term Evolution (LTE) modem or a legacy modem on a mobile terminal with both kinds of modems, and providing all legacy modem functions is disclosed. In addition, methods for dynamic selection of radio in a mobile terminal capable of Rich Communications Services (RCS) capabilities, and a method for redirecting RCS traffic to an alternate network interface is also disclosed. Methods for Session Initiation Protocol module (SIP) stack functions to be distributed across different processors on a mobile terminal, and directed to different network interfaces is disclosed. Methods of adding video calling and RCS functions without encountering the dual registration problem are also disclosed.

Abstract: Methods of IP to IP handover for VoIP calls are disclosed. Handover can occur using UDP in connectionless mode to switch networks, a hybrid approach including establishing both a TCP session and a UDP session and handing off using the UDP session, utilizing a network SIP proxy to maintain connection with the IMS server while the mobile device switches networks connecting the mobile device to the SIP proxy, using a modified Connection Manager that permits multiple IP connections simultaneously, and connecting via an on-device virtual network to an on-device router which reroutes calls to the appropriate network are detailed.
