Abstract: The present application concerns a method for identifying the nature of a bacterial infection from a peritoneal sample, in particular, whether it is a Gram-negative or Gram-positive infection, based upon the determination of one or more cellular and/or humoral markers in a sample.

Abstract: A photoacoustic gas sensor includes a hermetically sealed housing filled with a reference gas. The photoacoustic gas sensor furthermore includes a microphone arranged in the housing and configured to generate a microphone signal as a function of a sound wave based on light incident in the housing. Furthermore, the photoacoustic gas sensor includes a controllable heat source arranged in the housing and configured to selectively thermoacoustically excite the reference gas in order to generate a thermoacoustic sound wave phase-shifted with respect to the sound wave.

Abstract: A photoacoustic gas sensor is provided. The photoacoustic gas sensor includes a hermetically sealed housing filled with a reference gas. Further, the photoacoustic gas sensor includes a microphone system arranged inside the housing. The microphone system is configured to generate a first microphone signal comprising a first signal component related to a photoacoustic excitation of the reference gas and a second microphone signal comprising a second signal component related to the photoacoustic excitation. The photoacoustic gas sensor additionally includes a circuit configured to generate an output signal based on the first microphone signal and the second microphone signal by destructively superimposing a third signal component of the first microphone signal related to mechanical vibrations of the photoacoustic gas sensor and a fourth signal component of the second microphone signal related to the mechanical vibrations.

Abstract: An apparatus containing an optical emitter configured to emit optical radiation is provided. Further, the apparatus includes a first hermetically sealed measurement cell filled with a first gas. The first gas is configured to absorb the optical radiation at least partially at one or more predetermined wavelengths. Additionally, the apparatus includes a first microphone arranged in the measurement cell and configured to generate a first microphone signal on a basis of a photoacoustic excitation of the first gas by the optical radiation. The apparatus moreover includes an evaluation circuit configured to take the first microphone signal as a basis for generating a first measurement signal indicating an emission intensity of the optical emitter at the one or more predetermined wavelengths.

Abstract: An example of a system comprises a volume filled with a gas, a gas excitation device configured to excite the gas inside the volume, a microphone configured to output a microphone signal on the basis of the gas excited by the gas excitation device, and a testing unit configured to take the microphone signal as a basis for testing a gas-tightness of the volume. An example of a photoacoustic sensor comprises a hermetically sealed sensor cell, a gas excitation device and a testing unit configured to take the microphone signal dependent on the thermally excited gas as a basis for testing a gas-tightness of the sensor cell. One example comprises a method for testing a gas-tightness of a volume filled with a gas.

Abstract: A microelectromechanical light emitter component comprises an emitter layer structure of the microelectromechanical light emitter component and an inductive structure of the microelectromechanical light emitter component. The inductive structure of the microelectromechanical light emitter component is configured to generate current in the emitter layer structure by electromagnetic induction, such that the emitter layer structure emits light. The emitter layer structure is electrically insulated from the inductive structure.
