  • Publication number: 20120128140
    Abstract: A communication manager establishes a call between two or more participants on two or more communication devices. The call can be an audio or video call. A call request is sent from one of the communication devices to conference an additional communication device to the call. For example, a participant in the call decides to conference an additional person to further discuss an idea. An information manager gets a roster of the participants. In addition to the call request, the roster of the participants is sent to the additional communication device. The additional communication device receives the call request and the roster. The roster is displayed to the user of the additional communication device. The user can then indicate to answer the call request. If answered, the additional communication device sends an indication that the call was answered and the additional communication device is conferenced into the call.

  • Patent number: 8124491
    Abstract: Disclosed is a container capacitor structure and method of constructing it. An etch mask and etch are used to expose portions of an exterior surface of electrode (“bottom electrodes”) of the container capacitor structure. The etch provides a recess between proximal pairs of container capacitor structures, which recess is available for forming additional capacitance. Accordingly, a capacitor dielectric and a top electrode are formed on and adjacent to, respectively, both an interior surface and portions of the exterior surface of the first electrode. Advantageously, surface area common to both the first electrode and second electrodes is increased over using only the interior surface, which provides additional capacitance without a decrease in spacing for clearing portions of the capacitor dielectric and the second electrode away from a contact hole location.

  • Patent number: 8120300
    Abstract: An apparatus, system, and method are disclosed for fault tolerant cooling in a redundant power system. The apparatus receives power from a common power bus to power one or more power supply fans. The apparatus detects a non-functioning redundant power supply. The apparatus receives a fan control signal within a non-functioning redundant power supply. In addition, the apparatus uses the received fan control signal to synchronize a fan speed of a power supply fan within the non-functioning redundant power supply. The fan speed is synchronized with at least one fan control signal of a power supply fan within a functioning redundant power supply. Thus, the power supply fans of a non-functioning power supply continue to operate and are synchronized with power supply fans in functioning power supplies.
