    摘要: A method to perform secure boot procedure using a multi-stage security verification is provided. The procedure includes, within a microcontroller, referring to a table to identify a first defined memory region including code useful to start-up application programming of the microcontroller, wherein the application programming is operable to provide a function of the microcontroller to the vehicle, and a second defined memory region, including programming and data useful to operation of the application programming of the microcontroller. The procedure further includes, within a first stage, verifying authenticity of contents of the first region and starting-up the application programming of the microcontroller based upon verifying the authenticity of the contents of the first region. The procedure further includes, within a second stage, verifying authenticity of contents of the second region and operating the application programming to provide the function based upon verifying the authenticity of the contents of the second region.

    摘要: An impairment detection system is provided and includes an emitter, first and second beam selectors, a reference reflector, a sensor and a control module. The emitter is configured to emitter a first light signal. The first beam selector is configured to forward the first light signal to a touch probe. The reference reflector is configured to reflect the first light signal received from the first beam selector to generate a second reflected signal. The second beam selector is configured to receive (i) a first reflected signal from the touch probe based on reflection of the first light signal on an area of a person, and (ii) the second reflected signal. The sensor is configured to receive from the second beam selector the first reflected signal and the second reflected signal. The control module is configured to determine an impairment level of the person based on an output of the sensor.
