A method and system for transferring information from a first computer-based device to a web site, for temporary storage and later transfer of the stored information from the web site to a second computer-based device. First, a communication link is established between a first computer-based device and the web site. Next, the first computer-based device is scanned, via the web site, to determine the information contained on the first computer-based device. The user then selects which of the scanned information is to be uploaded from the first computer-based device onto the web site for temporary storage. Finally, the selected information is transferred from the first computer-based device onto the web site for temporary storage. Once retrieval of the temporarily stored information is desired, the user establishes a communication link between a second computer-based device and the web site. The second computer-based device is scanned, via the web site, to determine the information contained on the second computer-based device. The temporarily stored information, from the first computer-based device on the web site, is then displayed to the user and the user selects which of this temporary information, from the first computer-based device, is to be downloaded from the web site onto the second computer-based device. The selected information is finally downloaded from the website onto the second computer-based device.

Embodiments of the invention enable the synchronization of clocks across packet switched networks, such as the Internet, sufficient to drive a jitter buffer and other quality-of-service related buffering. Packet time stamps referenced to a local clock create a phase offset signal. A shortest-delay offset generator uses a moving-window filter to select the samples of the phase offset signal having the shortest network propagation delay within the window. This shortest network propagation delay filter minimizes the effect of network jitter under the assumption that queuing delays account for most of the network jitter. The addition of this filtered phase offset signal to a free-running local clock creates a time reference that is synchronized to the remote clock at the source thus allowing for the transport of audio, video, and other time-sensitive real-time signals with minimal latency.

The embodiments of the present invention enable multimedia communication use cases without the need for duplication of the state machine at each node, thereby conserving resources.

An improved information retention management mechanism is disclosed wherein an information set may be purged from an information system without having to delete the information set from the system. Whenever an information set enters an information system, a key is associated with the information set. The information set is encrypted using the associated key, and the encrypted form of the information set is stored in the information system. The unencrypted form of the information set is not stored. To render the information set to a user, the encrypted form of the information set is accessed along with the associated key, and then decrypted using the associated key to derive the original information set. Once derived, the information set is rendered to the user. So long as the associated key remains in the system, this process may be carried out to render the information set to a user. At some point, in accordance with an information retention policy, the information set is selected for purging. To purge the information set, all that needs to be done is to delete the associated key. By deleting the associated key, all copies of the encrypted information set stored within the information system are made unrenderable; as a result, the information set is effectively “purged” from the system. This purging is achieved without having to delete the encrypted information set from the system.

Remote Procedure Call (RPC) is implemented using XML-based message encoding wherein elements in the message corresponding to arguments of the RPC are associated with element type indicators selected from a defined set. The type indicators may allow the message itself to identify structural aspects of the message, particularly useful in the context of array elements, but useful for other types of elements as well.

A method for protecting an item of software, wherein at least one first challenge means is associated with said protected item of software, and at least one first response means accesses one private keying material. At least a third means (either challenge or response also exists). The first challenge means has no access to the said private keying material. The first response means proves to the first challenge means that the first response means has access to the private keying material. The first challenge means validates this proof using the public keying material that corresponds to the first response means' private keying material.

An illumination system comprises at least two light sources (101,102,103) having different emission spectra to one another; a detection circuit (131,132,133) for sensing a light intensity using at least one of the light sources as a photosensor; and driving means (161,162,163) for driving the light source in dependence on the sensed spectral distribution of light. The emission spectrum of a light source with the smallest bandgap overlaps the emission spectrum of a light source with the second-smallest bandgap. The illumination system is possible to measure the intensity of light emitted by the light source with the smallest bandgap by putting the light source with the second-smallest bandgap in detection mode. The illumination system may also sense the spectral distribution of ambient light, to allow the output from the illumination system to be adjusted in dependence on the ambient light.

Methods, apparatus, and systems are provided for tracking and analyzing data of consumer activity. The tracked data can be organized (e.g. as stored in cache, RAM, hard drives) in certain types of tables, where the tables can be associated with certain tags (keys) for efficiently accessing the data. The organization and associations of the data can also provide simple mechanisms for manipulating the data to obtain results specifically relevant for a task, such as detection of fraud or prediction of consumer behavior to provide better customer service or new services. For example, the tables may contain counters that store the number of times that two correlated consumer events occur within specific time intervals of each other. Such time data can provide efficient determination of patterns of consumer activity.

A vertical cavity surface emitting laser (VCSEL) is described using a sub-wavelength grating (SWG) structure that has a very broad reflection spectrum and very high reflectivity. The grating comprises segments of high and low refractive index materials with an index differential between the high and low index materials.
