Abstract: An electric drive unit is provided having an electric motor-generator coupled with a torque converter. Vehicles and machines employing the same, as well as methods of using the same, are also disclosed. The motor-generator may be configured to selectively drive a rotatable shaft with a motor output torque and generate electrical power from rotation of the rotatable shaft. The electric drive unit may further include a torque converter having an input and an output separated by a fluid coupling. The fluid coupling may be configured to selectively multiply torque received at the input such that a drive unit output torque at the output is selectively increased in at least a predetermined rotational speed range of the electric motor-generator.

Abstract: A system and method may collect telematics and/or other data, and apply the data to insurance-based applications. From the data, an insurance provider may determine accurate vehicle usage information, including information regarding who is using a vehicle and under what conditions. An insurance provider may likewise determine risk levels or a risk profile for an insured driver (or other drivers), which may be used to adjust automobile or other insurance policies. The insurance provider may also use the data collected to adjust behavior based insurance using incentives, recommendations, or other means. For customers that opt-in to the data collection program offered, the present embodiments present the opportunity to demonstrate a low or moderate risk lifestyle and the chance for insurance-related savings based upon that low or moderate risk.

Abstract: In systems and methods for accident scene reconstruction, accident data associated with a vehicle accident involving a driver may be collected. The accident data may include vehicle telematics and/or other data, and/or the driver may be associated with an insurance policy. The accident data may be analyzed and, based upon the analysis of the accident data, a sequence of events occurring before, during, and/or after the vehicle accident may be determined. Based upon the determined sequence of events, a virtual reconstruction of the vehicle accident and/or a scene of the vehicle accident may be generated. The virtual reconstruction may include images of vehicles and/or road, weather, traffic, or construction conditions at the time of the accident. Based upon the virtual reconstruction, fault of the driver, or lack thereof, for the accident may be determined. The determined fault may be used to handle an insurance claim associated with the vehicle accident.

Abstract: An apparatus comprising one or more pairs of analyzers measures light absorbing particulates, including black, brown, and ultraviolet light absorbing organic aerosols, suspended in gaseous samples, such as air. One analyzer receives an ambient gas sample, while the other analyzer is coupled to a dilution inlet that mixes ambient gas with a proportion of clean gas, whereby the two received samples have different particulate concentrations. Filters with identical filter areas accumulate particulates as the respective samples flow through with equal flow rate and velocity. An optical source and detector for each filter measures a changing property (e.g. attenuation at one or more wavelengths) as particulates accumulate. A computer uses the differential particulate accumulation from the ambient and diluted samples to compensate for filter loading effects upon the measurement to provide an accurate indication of particulate concentration in the ambient sample.

Abstract: In system and methods for theft prevention or mitigation, driver-related data associated with one or more authorized drivers of an insured vehicle may be collected over time. The authorized drivers and the insured vehicle may be covered by an insurance policy issued by an insurance provider. Based upon the collected driver-related data, a database associated with the authorized drivers may be built. Current driver-related data associated with an individual currently driving, attempting to start, or sitting in a seat of the insured vehicle may be collected. It may be determined, using both the database and the current driver-related data, that the individual is not among the authorized drivers. A disablement of an operation of the insured vehicle may be caused, and/or the individual may be caused to be prevented from starting or otherwise operating the insured vehicle, to facilitate preventing or mitigating theft of the insured vehicle.
