Abstract:
A method for switching from a multimedia broadcast multicast services (MBMS) download to a hypertext transfer protocol (HTTP)-based delivery of dynamic adaptive streaming over HTTP (DASH) formatted content in an internet protocol (IP) multimedia subsystem (IMS) network is disclosed. The method can include a service control function (SCF) module receiving a session initiation protocol (SIP) re-invitation from a mobile device while the mobile device is receiving a MBMS download in a content delivery session including DASH formatted content. The SCF module can send a SIP invitation to an HTTP/SIP adapter to select an HTTP server for an HTTP-based delivery. The SCF module can receive a SIP acknowledgement from the HTTP/SIP adapter indicating a selection of the HTTP server for the content delivery session. The SCF module can forward the SIP acknowledgement to the mobile device indicating a switch to the HTTP server for the content delivery session.

Abstract:
Complementary metal oxide semiconductor transistors are formed on a silicon substrate. The substrate has a {100} crystallographic orientation. The transistors are formed on the substrate so that current flows in the channels of the transistors are parallel to the direction. Additionally, longitudinal tensile stress is applied to the channels.
Abstract:
Described herein is an apparatus and system for generating a signal with phase angle configuration. The apparatus comprises an array of switch-resistors, each switch resistor to receive a control signal, wherein the array of switch-resistors to generate an output signal; and a circuit to configure phase angle of the output signal. The apparatus can be used for different package and inductor configurations. The apparatus provides flexibility to mitigate switching noise by adjusting phase angles, and provides the ability to enable and disable switch-resistors on the fly without ripples. The apparatus also saves power consumption by selectively turning off switch-resistors when phases are disabled. The output signal of the apparatus has smooth triangular waveforms for improving the quality of power supply generated using the output signal. Overall, the apparatus exhibits reduced sensitivity to process variations compared to traditional signal generators.

In one embodiment, each primary inductor is coupled to one of N input nodes (201-1, 201-2, 201-3, 201-4) and a common output node (205). The transformer further includes N-1 secondary inductors (222-242) coupled in series between one input node (201-1) and the common output node (250). In one embodiment, the N-1 secondary inductors (222-242) are arranged to couple energy from N-1 of the primary inductors (220-240) to provide a common node voltage (250) as an average of N input node voltages (201-1, 201-2, 201-3, 201-4), wherein N is an integer greater than two. Other embodiments are described and claimed.
