Abstract: Techniques are disclosed for analyzing a wireless communications device. The techniques include, for instance, assessing vulnerability of the device, including its susceptibility to jamming, by applying one or more interfering signals to the device and observing the device's response. The techniques further include identifying one or more vulnerabilities that can be exploited in defeating malicious behavior involving use of the device (e.g., such as using the device for remote detonation of explosives). Applying one or more interfering signals to the device may include, for instance, applying a trigger signal and a jamming signal to the device, and adjusting the jamming signal until the trigger signal is rendered ineffective in acting as a trigger signal. Identifying one or more vulnerabilities that can be exploited in defeating malicious behavior may include, for instance, reporting parameters of the one or more interfering signals that result in defeating the malicious behavior.

Abstract: A method of selecting textual advertisements for display on a web page based on user history. In the method, a user accessing a web site is identified. Keywords in articles displayed on web pages viewed by the user are identified and stored in a user profile. The advertisements displayed on a current user selected web page are based on keywords from the articles viewed by the user in the past that are stored in the user profile.
