20130197774SYSTEM AND METHOD FOR IDENTIFYING NON-EVENT PROFILES - A system for identifying non-events comprising an event capture device and one or more processors in communication with the event capture device. The event capture device is associated with a vehicle that captures driving event data. The one or more processors is configured to receive the captured driving event data; classify the captured driving event data as a non-event or driving event by comparing the captured driving event data to a non-event profile; in the event that the captured driving event data is classified as a non-event, store an abbreviated record of the captured driving event data.08-01-2013
20120059565OPTIMAL ENGINE OPERATING POWER MANAGEMENT STRATEGY FOR A HYBRID ELECTRIC VEHICLE POWERTRAIN - A method for managing power in a hybrid electric vehicle powertrain having multiple components including at least two of a group comprising an engine, a motor, a generator and a high voltage battery includes computing power losses for the individual components. An engine operating speed and torque for a given vehicle speed and total power command is determined so that total power losses for powertrain components are minimized.03-08-2012
20120095662ELECTRONIC ENGINE CONTROL SOFTWARE RECONFIGURATION FOR DISTRIBUTED EEC OPERATION - A system for configuring a full authority digital engine controller (FADEC) for use with an engine and an airframe combination. The system includes the FADEC and a data entry plug. The FADEC includes an electronic engine controller (EEC) attached to the engine, an airframe data concentrator (ADC) attached to the airframe, and a digital bus electrically connecting the ADC to the EEC. The ADC includes a data storage device and a data entry plug socket. The data entry plug includes electrical components configured for the engine and the airframe combination. The data entry plug is inserted into the data entry plug socket to direct the ADC to recall configuration data from the data storage device for the engine and the airframe combination and send the configuration data over the digital bus to the EEC.04-19-2012
20120095661DISTRIBUTED SMALL ENGINE FADEC - A full authority digital engine controller (FADEC) controls an engine attached to an airframe. The FADEC includes an electronic engine controller (EEC) attached to the engine, an airframe data concentrator (ADC) attached to the airframe, and a digital data bus electrically connecting the ADC to the EEC. The ADC is electrically connected to a plurality of airframe sensors to convert the airframe sensor signals to airframe sensor digital data. The digital bus conducts the airframe sensor digital data to the EEC.04-19-2012
