Appl. No.:

12/478257

Inventors:

Richard J. Skertic - Carmel IN, US

Assignee:

Anzen Electronics LLC - Carmel IN

International Classification:

G05B 19/00
G08C 19/00

US Classification:

340 564, 340 56, 340 585, 340 572

Abstract:

A vehicle security and monitoring control system having one or more vehicle security and monitoring control (VSMCM) controllers, one or more wireless remotes and one or more base stations connected to a computer. The VSMCM controller prevents operation of a vehicle in a safe manner by requesting protected state configuration changes within the control module within the vehicle when prompted to disable the vehicle, and changes the protected state configuration back to the original state within the control module when prompted to enable the vehicle. The wireless remote prompts the VSMCM controller to lock doors, unlock doors, enable vehicle operation or disable vehicle operation of the control module within the vehicle. The base station communicates with the VSMCM controllers to update and change operation of the controllers, as well as record events and vehicle information taken by the controllers.

Appl. No.:

12/868213

Inventors:

Steven J. Riggs - West Lafayette IN, US
Richard J. Skertic - Carmel IN, US

International Classification:

H04M 11/04
H04W 64/00

US Classification:

4554042, 4554561

Abstract:

A system and methodology for monitoring and restricting the use of a mobile communication device while operating a moving vehicle is disclosed. The mobile communications device environmental/geometrical context and the vehicle environmental/geometrical context are self determined, shared and stored locally. This information context is used to restrict a mobile communication device communication channel when motion conditions have been met. Further methods are disclosed to allow the mobile communication device to function normally when local vehicle location and synchronization have been established or an emergency communication channel initiated.

International Classification:

B64D 45/00
F02D 41/30
B64D 31/06
B64D 31/04

Abstract:

A system is described that includes a controllable component of an engine configured to regulate fuel flow to the engine, a digital control unit configured to control the engine by at least communicating with the controllable component of the engine, and a protection component configured to disable communication between the digital control unit and the controllable component of the engine. The system further includes an analog control unit configured to control the engine by at least communicating with the controllable component of the engine in response to the protection component disabling communication between the digital control unit and the controllable component of the engine.

Inventors:

- Indianapolis IN, US
Richard Joseph Skertic - Carmel IN, US

International Classification:

G05B 7/02

Abstract:

In some examples, a method includes determining, by a controller in a system, a result of a first control loop based on a first sensed signal in a first instance and determining, by the controller, a result of a second control loop based on a second sensed signal in a second instance. The method also includes clamping, by the controller, the result of the second control loop to be equal to the result of the first control loop in the first instance and clamping, by the controller, the result of the first control loop to be equal to the result of the second control loop in the second instance. The method further includes outputting, by the controller and to a component of the system, a control signal based on the result of the first control loop.

International Classification:

F02C 9/40
F02C 9/28
F02C 7/232

Abstract:

A gas turbine engine fuel additive control system includes a sensor positioned to sense an operational parameter of a gas turbine engine that includes a compressor section, a combustion section, and a turbine section. The system also includes a control valve positioned to supply a fuel additive to a fuel line. The fuel line contains fuel for supply to the combustion section of the gas turbine engine to which the fuel additive is selectively added by injection into the fuel line. The system also includes a controller configured to monitor the operational parameter in real time during operation of the gas turbine engine and adjust the control valve to dynamically modulate an amount of the fuel additive being supplied in the fuel in accordance with operation of the gas turbine engine.

Richard J. Skertic - Carmel IN, US

International Classification:

F01D 11/22
F01D 11/24
F01D 25/24

Abstract:

An assembly in a turbine engine having a dynamically moveable flowpath boundary member for encasing a rotatable bladed disc and maintaining a clearance gap between the flowpath boundary member and the blade tips of the bladed disc. The assembly comprises a static casing, a flowpath boundary member carried by the casing, and a refrigeration system configured to remove heat from the flowpath boundary member to thereby thermally expand and contract the flowpath boundary member to control blade tip clearance.

Assignee:

Rolls-Royce North American Technologies Inc. - Indianapolis IN

International Classification:

F04D 29/62
F01D 25/24
F01D 11/24

Abstract:

A system for controlling the clearance distance between an impeller blade tip of a centrifugal compressor and a radially inner surface of an impeller shroud in a turbine engine. The system comprises a thermal driver coupled between the impeller shroud and engine casing by hinged linkages. The thermal driver is coupled to a closed form refrigeration system having an evaporator, a compressor, a condenser, an expansion valve, and a refrigerant contained therein. The thermal driver is cooled by the refrigeration system, and the rate of cooling causes expansion and contraction of the thermal driver that is translated by linkages into axially forward and aft motion of the shroud.
