Abstract: It is determined whether an installed firmware of a device matches a reference firmware for the device. In response to a determination that the installed firmware of the device does not match the reference firmware for the device, different types of content sections of the installed firmware of the device are extracted. At least one of the content sections is identified as a dynamic section. A portion of the installed firmware selected to exclude at least the dynamic section is compared with a corresponding portion of the reference firmware to determine a comparison result. A security action is performed based at least in part on the comparison result.

Abstract: According to one embodiment of the present invention, a method for selecting metadata for sensor data streams may be provided. The method may include receiving a first sensor data stream associated with a user. The first data stream may be generated by one or more sensors co-located with the user. A plurality of tags that are each associated with one or more sensor value ranges may be accessed. A first tag may be selected from the plurality of tags according to a relationship between the first sensor data stream and the one or more sensor value ranges associated with the first tag. The method may further include facilitating reporting of the first tag.

Abstract: In one embodiment, modeling topics includes accessing a corpus comprising documents that include words. Words of a document are selected as keywords of the document. The documents are clustered according to the keywords to yield clusters, where each cluster corresponds to a topic. A statistical distribution is generated for a cluster from words of the documents of the cluster. A topic is modeled using the statistical distribution generated for the cluster corresponding to the topic.

Abstract: In particular embodiments, a method includes accessing data streams from a first group of physiological sensors monitoring a person, a second group of deconfounding sensors monitoring the person, and a third group of sensors monitoring a stressor, analyzing data sets collected from the person when the person is exposed and not exposed to the stressor, and determining a current stress factor for the stressor with respect to the person based on the analysis.

Abstract: The present invention provides a highly scalable architecture for a three-dimensional graphical, multi-user, interactive virtual world system. In a preferred embodiment a plurality of users interact in the three-dimensional, computer-generated graphical space where each user executes a client process to view a virtual world from the perspective of that user. The virtual world shows avatars representing the other users who are neighbors of the user viewing the virtual word. In order that the view can be updated to reflect the motion of the remote user's avatars, motion information is transmitted to a central server process which provides positions updates to client processes for neighbors of the user at that client process. The client process also uses an environment database to determine which background objects to render as well as to limit the movement of the user's avatar.

Abstract: In one embodiment, a set of target search terms for a search is received. Candidate terms are selected, where a candidate term is selected to reduce an ontology space of the search. The candidate terms are sent to a computer to recommend the candidate terms as search terms. In another embodiment, a document stored in one or more tangible media is accessed. A set of target tags for the document is received. Terms are selected, where a term is selected to reduce an ontology space of the document. The terms are sent to a computer to recommend the terms as tags.

Abstract: In particular embodiments, a method includes generating a 3D display of an avatar of a person, where the avatar can receive inputs identifying a type of a physiological event, a location of the physiological event in or on a person's body in three spatial dimensions, a time range of the physiological event, a quality of the physiological event, and rendering the physiological event on the avatar based on the inputs.
