  • Patent number: 7226448
    Abstract: Devices and methods provide for ablation of cardiac tissue for treating cardiac arrhythmias such as atrial fibrillation. Although the devices and methods are often be used to ablate epicardial tissue in the vicinity of at least one pulmonary vein, various embodiments may be used to ablate other cardiac tissues in other locations on a heart. Devices generally include at least one tissue contacting member for contacting epicardial tissue and securing the ablation device to the epicardial tissue, and at least one ablation member for ablating the tissue. Various embodiments include features, such as suction apertures, which enable the device to attach to the epicardial surface with sufficient strength to allow the tissue to be stabilized via the device. For example, some embodiments may be used to stabilize a beating heart to enable a beating heart ablation procedure. Many of the devices may be introduced into a patient via minimally invasive introducer devices and the like.

  • Patent number: 7221741
    Abstract: A telephone and voice mail (voice processing) system, which is implemented using only a single processing means for controlling operation of both the telephone system and the voice mail system, permits a user to call back a party using caller ID data stored with a voice mail message left by the party calling into the system. This is accomplished by storing caller ID information associated with an incoming call along with the message placed by the incoming caller and stored within the mailbox associated with the called party. Additionally, the caller ID information may be used to create a speed dial list within the telephone and voice mail system for later use by the user. Such caller ID information may be retrieved from a voice mail message left by the calling party, or may be retrieved while conducting a conversation with the incoming call.

  • Patent number: 7068684
    Abstract: An information handling system comprises a TCP/IP network connecting a hub to a multimedia server and the hub to a data server, and the hub to an IP telephony device that is then coupled to a network device. Data sent from the network device is addressed for transmission to the data server and is transmitted through the IP telephony device to the TCP/IP network. The IP telephony device monitors when an amount of data being received over the network falls below a predetermined threshold. If this occurs, the IP telephony device will send a signal to the multimedia server, which will then generate a congestion signal to send to all or selected IP telephony devices in the network to throttle data being received by the IP telephony devices from their respective connected network devices.

  • Patent number: 6940962
    Abstract: A telephone and voice mail (voice processing) system, which is implemented using only a single processing means for controlling operations of both the telephone system and the voice mail system, permits a caller, which has been placed on-hold, to request and be connected to another destination, such as another telephone extension in the system. Such a process may be performed by a recognition of digits dialed by the caller placed on-hold and then making a connection of the call to the requested extension number associated with the digits dialed.

  • Patent number: 6842505
    Abstract: A communications system, which has a plurality of terminals connected thereto, has one or more object presence detecting devices associated with the individual terminals. The detecting devices detect whether or not an object, such as a person, has been detected near any particular and associated terminal and informs the system. The telephone system can then provide a visual indication to other terminals within the system that a person is near their terminal. Such detecting capabilities can also be used to forward communications to another terminal if a user is not near their terminal.

  • Publication number: 20030125604
    Abstract: Tissue stabilization and ablation devices and methods provide techniques for stabilizing and ablating body tissues during surgical ablation procedures. In many embodiments, for example, devices may be used in minimally invasive techniques for ablating epicardial tissue adjacent one or more pulmonary veins to treat atrial fibrillation. Tissue stabilization and ablation devices generally include a rigidifying bladder coupled with an ablation member. The devices may additionally include a tissue stabilizing bladder or means within the rigidifying bladder for enhancing tissue stabilization. The rigidifying bladder conforms to a tissue surface and then stiffens to help the device hold its shape and position and to stabilize the tissue. The ablation member is then used to ablate an area of tissue. Such cardiac stabilization and ablation devices and methods may be used to ablate one or more patterns on the epicardial surface of a heart to treat atrial fibrillation and/or other cardiac arrhythmias.

  • Patent number: 6252944
    Abstract: A telephone and voice mail (voice processing) system is implemented using only a single processing means for controlling operations of both the telephone system and the voice mail system. The single processing means communicates with a hard disk, which stores programs for running the various operations of the system, voice prompts and all voice mail messages. The single processing means is coupled to signal processing circuitry, which emulates analog electronics that would be used for filters, tone decoder, generators, etc. The single processing means and signal processing circuitry are coupled to central office lines and station lines by a digital cross-point matrix, which can connect any voice path to another voice path. The system integrates call processing and voice processing into one system controlled by one set of software and a single processing means.

  • Patent number: 6160493
    Abstract: A low-cost and reliable radio warning system that alerts system users of potential hazardous conditions is disclosed. The system makes use of a transmitter and at least one receiver. The transmitter generates and transmits a radio warning signal that carries a digital data sequence that includes information concerning a particular potential hazardous condition from which the transmission was initiated, such as an approaching ambulance, fire truck, bus, train, or the like. Other information, such as GPS coordinates, may also be included. Through the use of digital encoding techniques, the system's susceptibility to false alarms or "false triggers" is minimized. The radio warning signal is transmitted in burst transmissions and may use a number of signaling techniques, including spread spectrum transmission, which increases system reliability and performance even in the presence of interference or multipath distortion.
