Abstract: A media marker mechanism may be used a cloud service to determine up-to-date context regarding playback of a media content stream on a user device. The cloud service may insert a media content item into a media content stream and/or combine media content items into a media content stream. The cloud service may implement the media marker mechanism to tag a content item with metadata that can be read by the user device. The user device can play the streaming media content and, when the tagged content item plays, read the metadata and send it to the cloud service. The cloud service can use the metadata to enrich the media content delivery by, for example, sending the user device a companion image to display, providing a link to make the companion image clickable, handling requests referring to the media content, etc.

Abstract: A media marker mechanism may be used to send, to a cloud service, up-to-date context regarding playback of a media content stream on a user device.

The user device can play the streaming media content and, when the tagged content item plays, read the metadata and send it to the cloud service.

Abstract: Techniques are described for maintaining contextual data to support content-related actions. In an example, a system stories second content at a source. The source is associated with first content. The system sends, to a device, an object that indicates the first content. From the device at a first time, the system receives first data indicating a first request for the second content and including source information that indicates the source. From the device at a second time, the system receives second data indicating a second request for the second content, the second data including the source information, the first data and the second data received at a frequency indicated by the object. The system determines that the requests are associated with the first content based on the source information included in the received data, and stores third data indicating a presentation of the first content by the device.

Abstract: A network security modeling system which simulates a network and analyzes security vulnerabilities of the network. The system includes a simulator which includes a network vulnerabilities database and a network configuration module having network configuration data. The simulator determines vulnerabilities of the simulated network based on the network configuration data and the vulnerabilities database.

Abstract: An inventive security framework for supporting kernel-based hypervisors within a computer system. The security framework includes a security master, one or more security modules and a security manager, wherein the security master and security modules execute in kernel space.

Abstract: A security framework for wrapping standard, commercially-available software applications in order to limit the amount of potential damage that a successful attacker or corrupt program can cause. The security framework includes a security master that coordinates installation and removal of kernel-based security modules and that provides a means for managing these modules. The security module are loadable kernel modules that include security information for enforcing application-specific or resource-specific policies. The security module are easy to install and require no modification to the existing operating system or to the software applications that they are monitoring. The security framework has a number of potential applications, including protecting a computing system from malicious software downloaded via a web browser, for wrapping web servers and firewalls in order to limit possible compromise and for replicating file operations.

Abstract: The incipient fire detector employs a particulate monitor for detecting particulates in the atmosphere. During an incipient fire condition, prior to ignition, a large mass of particulates less than 5 microns in size is generated by the combustible material which increases the concentration of such particulates in the atmosphere. The detector samples and responds to the rate of increase of such particulates to provide an alarm when such rate exceeds a predetermined rate indicative of a hazardous condition. The particle collector employed in the incipient fire detector is specially designed to collect particulates less than five microns in size and reject those above this size.
