摘要:
A device for electronic body monitoring, more particularly for infants, is disclosed. The device has a sensor part and a signaling part. The sensor part has a sensor apparatus for monitoring parameters of an infant, a fixation apparatus for affixing the sensor part to the infant and a first radio interface. The device includes an evaluation apparatus for evaluating the sensor signals and for triggering an alarm. The signaling part has a signaling apparatus for signaling the alarm and a second radio interface, which can at least receive data transmitted by the first radio interface.

A method for detecting a leak in an intake tract of an internal combustion engine involves operating the engine at two operating points and comparing a deviation of measured mass flows from expected mass flows at the first and at the second operating points.
摘要:
A method for detecting a leak in an intake tract of an internal combustion engine including the following steps: operating the internal combustion engine at a first operating point having a rotational speed and a first pressure difference between the ambient pressure and the pressure in the intake tract of the internal combustion engine; computing a first expected mass flow into the intake tract; measuring a first mass flow into the intake tract and computing a difference between the measured first mass flow and the first expected mass flow; operating the internal combustion engine at a second operating point having the same rotational speed and a second pressure difference between the ambient pressure and the pressure in the intake tract of the internal combustion engine, the second pressure difference being different from the first pressure difference; computing a second expected mass flow into the intake tract; measuring a second mass flow into the intake tract and computing the difference between the measured second mass flow and the second expected mass flow; and comparing the mass flow differences ascertained at the first and at the second operating point.
摘要:
An electronic functional adhesive bandage includes an adhesive layer and a cover layer, between which an electric energy source, an electric connection element, and an electronic control device are arranged. The electronic functional adhesive bandage also includes a switching element configured to control the power consumption of the electronic control device and to establish an electric connection between the electronic control device, the electric connection element, and the electric energy source.
