Abstract: A method for operating an optical detection device provided for monitoring at least one monitoring region is disclosed. The method includes actuating at least one light-emitting element to transmit a light signal, receiving at least one reflected light signal using at least two monitoring regions of at least one receiver, and using at least one received light signal to determine at least on receive variable. The eye safety of the detection device is checked by configuring at least one of the receiving regions as a measurement receiving region and at least one of the receiving regions as a test region, generating at least one measurement receive variable that characterizes a quantity of light captured in one measurement time interval, and generating at least one test receive variable that characterizes a quantity of light captured in one test time interval.

Abstract: Proposed is a process for producing methanol from synthesis gas by means of multi-stage, for example 2-stage, heterogeneously catalyzed methanol synthesis, wherein the methanol product formed in every synthesis stage is removed by condensation and the remaining residual gas is applied to the downstream synthesis stage or after removal of a purge stream recycled to the first synthesis stage as a recycle stream. According to the invention a substream is removed from the synthesis gas fresh gas and introduced into the second methanol synthesis reactor as a bypass stream.

Abstract: An airbag module for a motor vehicle, including a cover. The airbag may be deployed through an openable region of the cover into the outside space of the airbag module. When the airbag is inflated, the outflow orifice is arranged in the inside space of the airbag module such that gas emerging from the first outflow orifice passes through the openable region of the cover. The gas generator includes at least one gas outlet orifice fluidly connected to the airbag. The airbag module further includes a second openable outflow orifice, which is formed on a chamber surrounding the gas generator and is in fluid communication with the gas outlet orifice of the gas generator so that the gas flowing out through the gas outlet orifice is conducted at least partially into the outside space.
