A liquid sensor includes a light receiver configured to receive light. The light receiver is attachable to an outside of an accommodation unit into which a liquid is introduced and which has translucency. The light receiver receives light that has passed through the liquid in the accommodation unit or light reflected by the liquid, and outputs a signal related to a physical quantity of the liquid.

A sensor and method for determining the state of a humidification chamber in a respiratory gas humidifier. The sensor comprises a transmitter for emitting an electromagnetic radiation signal, a receiver for receiving the electromagnetic radiation signal and providing an output signal, and a controller for varying the intensity of the electromagnetic radiation signal emitted by the transmitter and/or the gain setting of the receiver. The controller has two sensor configurations, a first configuration in which the transmitter emits an electromagnetic radiation signal having a first intensity, the receiver has a first gain setting, and the receiver provides a first output signal, and a second configuration in which the transmitter emits an electromagnetic radiation signal having a second intensity, the receiver has a second gain setting, and the receiver provides a second output signal, wherein the first intensity is different to the second intensity, and/or the first gain setting is different to the second gain setting, and the controller determines a state of the humidification chamber by comparing the first and second outputs of the receiver with one or more threshold values.

The invention relates to an articulated vehicle including a plurality of vehicles or vehicle parts connected to one another in an articulated manner, a passage arranged between adjacent ones of the vehicles or the vehicle parts, the passage having an inner lining and an outer lining laterally spaced from the inner lining so as to define an empty cavity therebetween, one front wall on each side of the passage between the two adjacent vehicles or vehicle parts, the inner lining and the outer lining being arranged at the front walls of the two adjacent vehicles or vehicle parts while forming the empty cavity therebetween, a noise-absorbing noise insulation layer applied to a free surface on each of the front walls in the empty cavity between the inner and outer lining, wherein each of the noise-absorbing noise insulation layer extends into the empty cavity and terminates at a surface facing opposite to the each of the front walls respectively.

An atomization device according to the present invention is provided with: a main body part which has a container space that contains a hydrogen peroxide solution; and a diaphragm which is provided with through holes where the hydrogen peroxide solution contained in the container space passes, and which atomizes the hydrogen peroxide solution passing through the through holes.

This liquid surface detection device comprises: a liquid retention part in which hydrogen peroxide water is retained, the hydrogen peroxide water to be atomized by a vibrating plate in which a through-hole is provided; a float positioned inside the liquid retention part; and a sensor that detects, via the float, the arrival of the liquid surface of the hydrogen peroxide water retained in the liquid retention device at a prescribed position.

An automatic liquid density measurement device includes a receptacle configured to contain the liquid, a float configured to be submerged in the liquid when it is contained in the receptacle, and an electronic system. The electronic system includes a first electromagnetic sensor configured to make a reference measurement relative to the electrical properties of the liquid, a second electromagnetic sensor configured to make a measurement of the volume of the liquid displaced when the float is submerged in the liquid, and an electronic circuit coupled with said first and second electromagnetic sensors to determine the density of the liquid based on the measurement of the physical properties of the liquid and the measurement of the volume of the liquid displaced.
