One embodiment of the present invention provides a system for determining whether software is likely to exhibit malicious behavior by analyzing patterns of system calls made during emulation of the software. The system operates by emulating the software within an insulated environment in a computer system so that the computer system is insulated from malicious actions of the software. During the emulation process, the system records a pattern of system calls directed to an operating system of the computer system. The system compares the pattern of system calls against a database containing suspect patterns of system calls. Based upon this comparison, the system determines whether the software is likely to exhibit malicious behavior. In one embodiment of the present invention, if the software is determined to be likely to exhibit malicious behavior, the system reports this fact to a user of the computer system. In one embodiment of the present invention, the process of comparing the pattern of system calls is performed on-the-fly as the emulation generates system calls.

A method for accurate signal detection begins by receiving a radio frequency signal, which is then converted into baseband signals. The processing then continues by performing a normalized auto correlation on the down-converted baseband signal to produce a normalized auto correlation signal. The process continues by performing a periodic pattern detection on the down-converted baseband signal to produce a normalized detected periodic signal. The process then continues by comparing the normalized auto correlation value with an auto correlation threshold and by comparing the normalized detected periodic signal with a set of thresholds. When the normalized auto correlation value compares favorably with the auto correlation threshold and when the normalized detected periodic signal compares favorably with the set of thresholds, the down-converted baseband signal is indicated to be a valid signal.

A video game controller for home video game systems is situated between a player's feet and is used to detect positions outside the footprint of the controller. The controller transmits the position data to the video game system and enables game play. In dance games, the controller detects dance steps when the player dances around the controller. A signal is transmitted from locations at the perimeter of the controller, reflected by the player's foot, and then received back at the controller. In a preferred embodiment the location is detected as a function of the time the signal is transmitted / received and by the matrix of signals received. Modulation of the transmission and reception minimizes detection of noise and distant reflections and therefore minimizes or eliminates false position detection.
