A behavioral modeling technique that captures driver delay. The output characteristics of a typical driver are represented by two basic element types: switching and non-switching. Switching elements are functions of both time-varying and non-time-varying parameters, and non-switching elements are functions of non-time-varying parameters only. The outputs of these elements are characterized and tabulated by applying a DC voltage on the output of the driver and measuring the current through each element. The time-varying switching element are represent by time-controlled resistors. The invention provides a methodology to account for variations in input transition rate, supply voltage(s) or temperature.

The present invention described secures a computer account against unauthorized access caused as a result of identity-theft, and insider-espionage using artificial intelligence and behavioral modeling methods. The present invention has the ability to detect intruders or impersonators by observing “suspicious” activity under a computer account. When it sees such suspicious behavior, it uses artificial intelligence to authenticate the suspect by interrogation. The present invention asks the suspect questions that only the legitimate computer account owner can verify correctly. If the suspect fails the interrogation, that proves that he / she is an impersonator and therefore further access to the computer account is denied immediately. On the other hand if the suspect passes, access to the computer account is restored. The present invention uses a Programmable Artificial Intelligence Engine (PAIE) to interact with computer users in human natural language. The PAIE can also be programmed to suit other applications where natural language interaction with humans is helpful.

A communications controller is provided for empowering the user of a communications device, such as a telephone or other device, to assume control over incoming communications. This communications controller is based on artificial intelligence and behavior modeling techniques. Each communication is identified by unique identification information associated with an incoming communication. The user selects one of a plurality of different priority rating levels for a particular communication. The user also selects or infers block time intervals for each priority to indicate times during which incoming communication is not desired. Dynamic communications control is achieved by also determining the mood of the user or mode of the device. Undesirable communications will be “blocked”. For example, when that particular caller places a call to the user, the user's communication controller determines the caller's identification information and recalls the priority and corresponding blocking time interval for that particular caller. The user's mood or the mode of the communications device is determined. The call is accordingly passed to the communication device or blocked.

A hardware design emulation system that includes one or more emulators and one or more associated run-time assist units (RTAUs). The emulator logic is a combination of user model logic, reflecting the hardware design, and non-user model logic. A handshaking controller produces a domain step signal and a model step signal. The domain step signal indicates that the emulator is entering a state for executing the next step of the logic with which it is programmed, be it user model logic or non-user model logic. The model step signal indicates that the emulator is entering a state for advancing the user model defined by the user model logic. This dual handshaking protocol enhances versatility by enabling a wide variety of RTAUs to be used, particularly in combination with one another. Also, a RTAU can, in accordance with its programming, "skip steps" (either model steps or domain steps) to enhance efficiency if there is a known relationship between cycles of the emulator logic and cycles of the user model. In addition, system stoppage logic efficiently alerts other RTAUs when one RTAU has caused the emulation to stop. Furthermore, the emulation system can be scaled to accommodate a greater number of RTAUs by cascading the master panels to which they are connected.
