20130154586 | SYSTEM AND METHOD FOR CONTROLLING OUTPUT RIPPLE OF DC-DC CONVERTERS WITH LEADING EDGE MODULATION CONTROL USING CURRENT INJECTION - In a preferred embodiment, a voltage converter comprises a voltage converter circuit, an output adjuster and a controller. The controller provides a control signal at a duty ratio determined dynamically by a set of input signals. The dynamic output adjuster determines the set of input signals by adjusting the ac component of an output voltage based on a gain Q. The dynamic output adjuster alleviates dependence on the value of R | 06-20-2013 |
20140361754 | ANALOG INPUT OUTPUT LINEARIZATION CONTROL - A voltage converter for converting an input voltage to an output voltage is disclosed. The voltage converter includes a voltage converter circuit having a set of switches, a switch driver connected to the voltage converter circuit, a controller connected to the switch driver and the output voltage, a target output voltage connected to the controller, a control signal generated by the controller for the switch driver that includes a duty ratio based on the target output voltage and the output voltage. The switch driver is configured to apply the control signal to the set of switches and the voltage converter circuit generates the output voltage based on the duty ratio to match the target output voltage. | 12-11-2014 |

20110149948 | ON-NET DIRECT ACCESS TO VOICEMAIL - A device in a provider network receives a Session Initiation Protocol (SIP) request message from an originating device, where the SIP request message includes a general number for a voicemail service and where the voicemail service includes multiple voicemail systems. The device determines whether the originating device is associated with a voice-over-Internet-protocol (VoIP) account on the provider network and, when the originating device is associated with a VoIP account, selects a direct access number assigned to a voicemail system, from the multiple voicemail systems in the network, that services the VoIP account. The device also associates the direct access number and the SIP request message, and forwards, based on the direct access number, the SIP request message to an application server. | 06-23-2011 |
