摘要:
A method for passive cancellation of substrate noise for a buck converter uses an on-chip capacitor to reduce the substrate noise. The capacitor achieves a close-magnitude noise with opposite phase for better noise cancellation effect in the substrate. The capacitor can be realized as a MOS capacitor, NMOS isolation ring n-well capacitor, n-well junction capacitor, isolated p-well junction capacitor, etc. The capacitor is easy to implement. Further, bond wire parasitic inductance in the buck converter is used to reduce substrate noise.

A method, system, and relevant apparatuses for selecting a Multimedia Ring Back Tone (MRBT) are disclosed. The method for selecting an MRBT includes: receiving a call request sent by a calling party, where the call request carries an MRBT type required by the calling party; sending the MRBT type required by the calling party to the MRBT server; obtaining MRBT information sent by an MRBT server, according to the MRBT type required by the calling party; and sending the MRBT information to the calling party. With the present invention, the calling party sends the required MRBT type, and the MRBT server provides the corresponding MRBT information for the calling party. Therefore, the calling party has an opportunity of selecting the MRBT type required by the calling party, and thus user experience is improved.

The present invention provides a method and apparatus of synchronizing AAL2 path states between ATM adaptation layer type 2 (AAL2) signaling nodes, wherein a AAL2 signaling node as a synchronization requesting end sends a path state request message to a peer AAL2 signaling node of an AAL2 path, the peer AAL2 signaling node performs local check on the state of the AAL2 path designated by the request message after receiving the request message, and the peer AAL2 signaling node controls consistency synchronization processing on the AAL2 path states at two ends based on the result of the check. The present invention may avoid initial call failure incurred by inconsistency between states at two ends of an AAL2 path and improves success ratio of AAL2 path establishment.

The present disclosure describes various antenna assemblies, each antenna coil being disposed about a tool body section in an antenna pathway. The antenna pathway passes through alternating grooves and lands. In each embodiment, at least one of the grooves is disposed in the tool body section at a non-axial direction relative to the longitudinal axis of the tool body section. In an embodiment, the antenna coil is an axial coil or a tilted coil. Additional grooves oriented at axial direction may be disposed on the tool body section. Each of the antenna assemblies disclosed may be employed in an electromagnetic logging tool for providing directional measurements while drilling.

A method, system, and apparatus for processing a service message with multiple terminals are disclosed. The method includes: receiving a request message from a terminal, where the request message carries request information of the terminal; and sending a service message to the terminal according to the request information. When a user has multiple terminals, the PPG selects a specific terminal for receiving an incoming service according to the SUBSCRIBE request of the terminal and the terminal request information carried in the SUBSCRIBE request. When a service arrives, the service message is sent to the selected terminal, thus avoiding sending of the service message to all terminals of the user.
