    摘要: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a light-to-frequency sensor conversion. In some implementations, a first output waveform is generated from a light signal, a frequency of the first output waveform being based on an intensity of the light signal, including integrating the light signal across multiple clock cycles. In response to receiving a notification, a hold operation is performed to stop integrating the light signal for a period of time. In response to an end of the hold operation, a second output waveform is generated that includes integrating the intensity of the light signal starting from the end of the hold operation over a count of the multiple clock cycles that start after the end of the hold operation by a delay amount. The first output waveform and the second output waveform are summed to determine the intensity of the light signal.

    摘要: An airbag venting device (10) comprises a housing (24) which includes a first flow orifice (18) facing away from the airbag (12) and a second flow orifice (20) facing the airbag (12). The housing (24) has an axial total length (26), the first flow orifice (18) has a first axial opening length (34) and the second flow orifice (20) has a second axial opening length (34). An adjustable closure element (22) assigned to the housing (24), in an open position, releases at least one of the two flow orifices (18, 20). An actuator device (30) interacts with the closure element (22) to release and/or to close the flow orifice (18, 20), and, in doing so, the axial total length (26) of the housing (24) is less than 3 times the length of the longer axial opening length (34) of the two flow orifices (18, 20).
