Abstract: The present invention provides a system and method for degrading and disabling a vehicle's engine throttle. The vehicle disable system includes a throttle position sensor that generates a throttle position signal, an electronic control module (“ECM”) input connected to the ECM on which the throttle position sensor provides the throttle position signal to the ECM, and an override input that enables an idling signal to be transmitted to the ECM instead of the throttle position signal. The method of the present invention includes the steps of receiving an input signal related to the state of the driver input mechanism, interpreting the input signal, and at least one of degrading and disabling the throttle based on the interpretation of the input signal.

Abstract: A technique for providing management of a motor vehicle information system includes a number of steps. Initially, a wake-up message is received from a portable transmitter. In general, the wake-up message, unique to the portable transmitter, is provided responsive to user activation of a button that is electrically coupled to the portable transmitter. Next, it is determined whether power capability of the motor vehicle is adequate responsive to receipt of the wake-up message. When the motor vehicle power capability is adequate, power is provided to a wireless interface, a vehicle information system and a mass storage device, all of which are located within the motor vehicle. Information is then received via the wireless interface and stored in the mass storage device, when the power capability of the motor vehicle is adequate.

Abstract: A vehicle disable system including an onboard computer linked to a throttle control relay. The onboard computer is capable of communicating to a remote control center by way of telecommunications link. If certain security protocols are breached, the control center communicates a shutdown command to the vehicle by way of the telecommunications link and the vehicle initiates a shutdown procedure for incapacitating the vehicle throttle controls.

Abstract: Techniques for providing static and dynamic event data are disclosed. In one implementation, a mobile user interface device has the capability to determine whether static event data has been received, determine whether an event wireless network has been detected, establish a wireless network session if an event wireless network has been detected, and determine whether dynamic event data has been received in a wireless network message. When static and/or dynamic event data have been received, a user interface may be generated to present at least some of the static event data and at least some of the dynamic event data. A wireless network may have the capability to determine whether a wireless network session is authorized and to determine the level of service required for the session.

Abstract: A method of detecting combustor dynamic pressures in combustors of a gas turbine combustor includes the steps of: a) mounting at least one accelerometer (24) on a combustor casing; b) establishing a baseline vibration signature for the casing when combustion dynamics are minimal; and c) measuring subsequent vibration signatures and comparing those signatures to the baseline signature.

Abstract: A multichannel data acquisition system for physical measurements on rotating members of operating machinery avoids slip rings and radio telemetry for data transfer by providing a capacitive coupling link between rotating and stationary members. Electronic circuitry mounted on the rotating member provides a pulse-code modulated signal containing the measured information for transmission through the capacitive coupling link. Power required to operate the rotating circuitry is inductively coupled from a stationary high-frequency source. The rotating circuitry includes a digital counter whose count is incremented by a momentary power interruption and whose digital output corresponds to a particular measuring range, allowing a range selection to be made during machinery operation.
