| 20080320024 | Portal and Key Management Service Database Schemas - In a pay-per-use computer environment, particularly when network access is limited, self-monitoring tools on a pay-per-use computer may require special support from a host/server. The host/server must be able to respond to requests quickly and efficiently and yet maintain full information required to service requests and updates. A key management table and a device management table provide critical information required to service requests. Use of SQL notifications allows local database caches to remain current but quickly accessible. | 12-25-2008 |

| 20090099634 | CONDUCTIVE COMPOSITE ELECTRODE MATERIAL - A medical electrical lead and body implantable electrode suitable for a variety of medical applications are disclosed. In general, the electrode includes a composite material having particles of pseudo-capacitive material, such as iridium oxide, dispersed within a polymer matrix including a polyelectrolyte. The polymer matrix can also include a conductive polymer doped with an excess of the polyelectrolyte. The composite may used to form the electrode itself or an electrode coating. The presence of a pseudo-capacitive material within the composite may increase the charge-storage capacity of the electrode and may allow for safe deliveries of charge densities within an electrochemical window suitable for pacing a patient's heart. | 04-16-2009 |
| 20100030326 | Bioerodible Endoprosthesis - An endoprosthesis includes a plurality of struts defining a flow passage. At least one strut includes (a) a body comprising a bioerodible material and having a thickness and (b) a coating overlying the body. The coating includes a plurality of regions that allow physiological fluids to contact a plurality of corresponding areas of the underlying body when the endoprosthesis is implanted in a physiological environment. The plurality of regions are sized and arranged so that the contacted areas of the body erode substantially through the body in the thickness direction while the coating remains on the body when the endoprosthesis is implanted in the physiological environment. | 02-04-2010 |

| 20090003533 | MANAGEMENT AND DIAGNOSIS OF TELEPHONIC DEVICES - Systems and methods of managing and diagnosing enterprise telephonic devices are disclosed. A provisioning request can be received from an enterprise telephonic device. The provisioning request can include a domain name system lookup request. An enterprise network address of a device management server can be provided to the enterprise telephonic device. A voice data link can be established with the enterprise telephonic device so as to permit the enterprise telephonic device to communicate over a data network with endpoint telephonic devices. The device management server can periodically receive heartbeat data from the enterprise telephonic device. The heartbeat can be indicative of a status of at least one functionality of the enterprise telephonic device. The enterprise telephonic device can provide diagnostic logs when requested by the device management server. In addition, the enterprise telephonic device can be configured to periodically request software updates. | 01-01-2009 |
| 20090007091 | Techniques for automatic software provisioning - Techniques to perform automatic software provisioning are described. An apparatus may comprise a provisioning database, a client provisioning module and a network interface. The provisioning server may be operative to store software update packages for different packet telephony devices. The client provisioning module may be operative to automatically provision packet telephony devices in response to provisioning requests from the packet telephony devices. For example, the client provisioning module may receive device configuration information for a packet telephony device, and retrieve a software update package from the provisioning database based on the device configuration information. The network interface may send the software update package to the packet telephony device on behalf of the client provisioning module. Other embodiments are described and claimed. | 01-01-2009 |

| 20110185166 | Slider Control for Security Grouping and Enforcement - A group of security functions may be configured and managed by organizing the security functions and their features into a ranked list and made available through an administrative console. The ranked list may represent various levels of security from which a user may select. Once selected, the security functions may be configured according to the selected level. The console may determine a current security level by analyzing the configuration or status of each of the security functions and presenting a single status level from the ranked list determined by the least secure setting of the various security functions. | 07-28-2011 |
