To date, the universal metric for road safety has been historical crash data, specifically, crash frequency and severity, which are direct measures of safety. However, there are well-recognized shortcomings of the crash-based approach; its greatest drawback being that it is reactive and requires long observational periods. Surrogate measures of safety, which encompass measures of safety that do not rely on crash data, have been proposed as a proactive approach to road safety analysis. This white paper provides an overview of the concept and evolution of surrogate measures of safety, as well as the emerging and future methods and measures. This is followed by the identification of the standards needs in this discipline as well as the scope of SAE’s Surrogate Measures of Safety Committee.

In this paper, we present a universal architecture for a reliable self-powered Smart Sensor Interface (SSI) in avionic applications. The SSI module consists of data acquisition and signal excitation paths. The power recovery unit harvests energy from data field bus to power up the SSI module entirely. Using integrated CMOS technologies, the interface is flexible and configurable to be integrated with and fully controlled by Transducer Interface Module (TIM) introduced in IEEE1451 standard. Employing data converters within the signal paths makes the SSI well suited for full digital control over specifications of the excitation signal and data processing algorithms. The interface can be used along with various types of position sensors including legacy R/LVDT, MEMS-based and optical ones. The analog parts of the SSI are implemented using IBM 0.13 μm CMOS process while its digital modules are realized in FPGAs. The Power Conversion Chain (PCC) of the SSI is also presented and its complex components are modeled in Verilog-A using a top-down modeling approach. The models make it possible to study over power transfer and…

SAE MOBILUS® Search Tips
Please note: All terms not contained within quotes, will be evaluated using the OR operator. This means that your search results will contain all results that contain ANY of the entered terms.
AND, OR, NOT
SAE MOBILUS supports the use of the AND, OR and NOT BOOLEAN operators ONLY function with the Advanced Search.
Using the asterisk, ( * ) allows you to search for a partial word. For example, entering a keyword search of aero* will search for any word beginning with aero.
Using the question mark, ( ? ) allows you to search for a word with a single character wildcard. For example, searching for t?re would match both tire and tyre
Words in double quotes " " are treated as a phrase. Conducting a search for "heat model" will return all results in which the exact phrase "heat model" is found, while "heat modeling" would NOT be included.
A term combined with a phrase will be joined with an OR operator.
Searching for Standards
When searching for a standard please use the entire Document Number assigned, which includes the abbreviation. A space can be used, or omitted between the abbreviation and number.
