An implanted medical device (e.g. infusion pump) and an external device communicate with one another via telemetry messages that are receivable only during windows or listening periods. Each listening period is open for a prescribed period of time and is spaced from successive listening periods by an interval. The prescribed period of time is typically kept small to minimize power consumption. To increase likelihood of successful communication, the window may be forced to an open state, by use of an attention signal, in anticipation of an incoming message. To further minimize power consumption, it is desirable to minimize use of extended attention signals, which is accomplished by the transmitter maintaining an estimate of listening period start times and attempting to send messages only during listening periods. In the communication device, the estimate is updated as a result of information obtained with the reception of each message from the medical device.

In a system for providing access control management to electronic data, techniques to secure the electronic data and keep the electronic data secured at all times are disclosed. According to one embodiment, a secured file or secured document includes two parts: an attachment, referred to as a header, and an encrypted document or data portion. The header includes security information that points to or includes the access rules and a file key. The access rules facilitate restrictive access to the secured document and essentially determine who / when / how / where the secured document can be accessed. The file key is used to encrypt / decrypt the encrypted data portion. Only those who have the proper access privileges are permitted to retrieve the file key to encrypt / decrypt the encrypted data portion.

Methods, apparatuses and systems that facilitate the classification of web services network traffic. In one implementation, the present invention provides an automated mechanism that facilitates synchronization of a web services traffic classification database with the current or latest definitions of one to a plurality of web services of interest. In one implementation, the present invention processes interface definitions corresponding to a given Web service to construct a traffic classification configuration for the Web service, including one or more traffic classes and corresponding matching rules or attributes for each traffic class. In one implementation, the present invention automatically creates traffic classes and matching rules that allow for differentiation between the operations supported by a Web service. Implementations of the present invention provide a mechanism allowing for classification of Web services network traffic on a granular basis to enhance network monitoring and analysis tasks, as well as network control functions, such as bandwidth management, security and other functions.

The aim is to provide high-speed data synchronization. To achieve the aim, in data synchronization using a plurality of key databases with respect to same data pieces, a key for one key database, which has been determined in advance, is used for updating the data piece managed under the other key database. This reduces the number of key decryption operations. A key management software 116, which manages a key database A120 and a key database B121 each having a tree structure, determines whether to perform data synchronization when requested by an upper-level application to perform data encryption, and performs synchronization of encrypted data by using a key of the other database which has been determined in advance. This reduces the number of times the encrypted key is loaded onto a cryptographic processing unit 114, and realizes high-speed cryptographic processing on data.

Techniques for securing electronic data and keeping the electronic data secured at all times are disclosed. According to one embodiment, a client module in a client machine is configured to provide access control to secured documents that may be located in a local store, another computer machine or somewhere over a data network. The client module includes a document-securing module configured to operate in a path through which a document being accessed is caused to pass so that the document can be examined or detected for the security nature. If the document is secured, the document-securing module obtains a user or group key to decrypt security information in the secured document for access rules therein. If a user accessing the document is determined to have the access privilege to the secured document, a file key is retrieved from the security information and a cipher module is activated to decrypt the encrypted data portion with the file key. Likewise, if a document is to be secured, the cipher module encrypts clear data from the document to create the encrypted data portion. The document-securing module integrates proper or desired security information with the encrypted data portion to produce the secured document.

A machine-to-machine (M2M) gateway (GW) includes reachability, addressing, and repository (RAR) capability. The GW maintains a local mapping table and local device application repository, performs data aggregation, address / name translation, provides event reporting and establishes GW reachability and wake-up time. The GW supports requests from M2M applications or other capabilities within the GW, and from a network and application (N&A) domain RAR. The GW may include an M2M device and M2M gateway management (MDGM) capability that receives management requests for an M2M device and functions as a network proxy. The MDGM accepts and processes requests from the N&A domain on behalf of the M2M device and performs management functions of the M2M device on behalf of the N&A domain. The MDGM may request the N&A domain for permission to interact with the M2M device, initiate an interaction for device management tasks with the M2M device, and report to the N&A domain.

Interference in ultrasound imaging when used in connection with high intensity focused ultrasound (HIFU) is avoided by employing a synchronization signal to control the HIFU signal. Unless the timing of the HIFU transducer is controlled, its output will substantially overwhelm the signal produced by ultrasound imaging system and obscure the image it produces. The synchronization signal employed to control the HIFU transducer is obtained without requiring modification of the ultrasound imaging system. Signals corresponding to scattered ultrasound imaging waves are collected using either the HIFU transducer or a dedicated receiver. A synchronization processor manipulates the scattered ultrasound imaging signals to achieve the synchronization signal, which is then used to control the HIFU bursts so as to substantially reduce or eliminate HIFU interference in the ultrasound image. The synchronization processor can alternatively be implemented using a computing device or an application-specific circuit.

A system and apparatus for control and distribution of data files in large-scale distributed networks. Members of a group of servers in a multicast network elect a group leader whenever a new group leader is required, as detected by absence of a periodic message published by the leader. Election is carried out by a system of voting by each candidate whereby each candidate has a priority calculated from its configuration, and the server with the highest priority is configured to claim the leadership faster than the other candidates. As part of the claim, each candidate multicasts its priority. Each candidate that receives a multicast claim for leadership from another candidate compares its own priority against the claimant and only votes for itself if its own priority is higher. After a preconfigured period of hearing no other claimants with higher priority, the candidate with the highest priority becomes the new leader.

Real time data integration services are deployed in a services oriented architecture for supply chain management.

A media spooler system is described that provides a methodology for efficient transmission of media content from client devices, such transmission of digital images from wireless digital cameras. The media spooler or gateway addresses wireless transmission problems by acting as a protocol gateway between a thin-client device and a target host or server (supported by a server infrastructure). More particularly, the media spooler of the present invention acts as a protocol gateway between thin-client devices (e.g., “mobile visual communicator” in the form of a wireless digital camera) and server infrastructure (e.g., server-based computer systems or “Web servers” of a photographic service provider). This task entails accepting multiple, simultaneous connections from various client devices (e.g., wireless digital cameras), extracting information from those devices (e.g., digital photographs or other media content), and then uploading that information to the target server infrastructure. In basic operation, the media spooler queries each client device for the information (e.g., media, such as pictures) the client device thinks should uploaded, and then the media spooler queries the server infrastructure for the subset of pictures that have not been already uploaded. This improved coordination or synchronization of information between a device and target host allows for efficient recovery of dropped cellular data calls by essentially allowing the media spooler to “pick up where it left off.”
