摘要： A switch and method for adjusting the switching threshold of a contactlessly operating proximity switch comprising a sensor for converting a physical variable into an electric sensor signal S(x), a control unit for evaluating the electric sensor signal S(x) and for generating a binary switching signal by comparing with a switching threshold Sein, and comprising an operating element for adjusting the switching threshold Sein according to a control value P, wherein the control value P is mapped in a non-linear manner on the movement path of the operating element, wherein the resolution of the operating element is largest when the electric sensor signal S(x) is in the vicinity of the switching threshold Sein(P) and decreases in a non-linear manner at increasing distance such that the influence of the switching threshold Sein(P) is fine in the vicinity of the current sensor signal S(x) and increasingly coarser at increasing distance.

摘要： The invention relates to a housing comprising a venting device (10) which is arranged on the housing (2) and which allows an ambient pressure to be supplied to the interior of the housing (2). The venting device (10) is made of a sleeve-like protective cap (11) with lateral openings (12) and a liquid-repellant membrane, and a cavity for receiving the membrane is formed in the interior of the venting device (10). The membrane is arranged such that an opening, which is provided for the pressure supply, in the wall of the housing (2) is covered. In order to prevent the so-called teapot effect and therefore allow a light dripping of a liquid on the venting device (10), the sleeve-like protective cap (11) has a narrow circumferential expansion (14) in the region of the lateral surface of the protective cap such that a defined dripping edge is formed.

摘要： The invention relates to a method for monitoring the function of a capacitive pressure measurement cell (10) which has a measuring capacitor (CM) and a reference capacitor (CR), to which an internal excitation voltage UE0 in the form of an alternating square-wave signal is applied. According to the invention, in order to allow the detection of a disturbing influence on the measurement result owing to, in particular, moisture-induced leakage currents, it is proposed that the corresponding voltage values U1, U2 be sensed from the voltage signal UCOM during the falling and/or rising signal curve at least two defined times t1, t2, and the two pairs of values t1; U1 and t2; U2 are used to determine a linear equation U=f(t), wherein the linear equation U=f(t)
within the falling or rising signal curve is used to calculate the time tx at which the voltage value Ux set as a threshold value or switchover point in the comparator-oscillator (SG) is reached, wherein—either the time tx is compared with the actual switchover time of the comparator-oscillator (SG) and an error signal is generated in the event of significant deviation,—or the time tx is used to define a hypothetical switchover point of the comparator-oscillator (SG), from which a hypothetical working frequency is calculated, and an error signal is generated if there is significant deviation of said hypothetical working frequency from the actual working frequency of the comparator-oscillator (SG).

摘要： The disclosure relates to a device for converting a pressure into an electric signal. The device has a first deformation body in the form of a first membrane, via which the pressure can be introduced into the device, and a second deformation body in the form of a second membrane, by means of the deflection of which the applied pressure can be converted into an electric signal. The device has a force transmitting means for transmitting pressure and/or tensile forces from the first deformation body to the second deformation body. Either the force transmitting means is designed as a separate part and the two membranes have a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to the respective membrane, or the force transmitting means is integrally formed with one of the two membranes and the corresponding other membrane has a bore into which the force transmitting means is at least partly introduced and in which the force transmitting means is connected to said membrane.

摘要： A time-of-flight camera includes a photosensor and a reference photosensor. Each of the photosensors have accumulation gates and each are configured as a photomixing detector (PMD). A readout device is connected to the accumulation gates of the photosensor and to the accumulation gates of the reference photosensor. The readout device is configured to read out an electric quantity that corresponds to a charge that is present at respective ones of the accumulation gates. An integration time of accumulating the charges is the same for the photosensor and for the reference photosensor and is dimensioned so as to prevent the reference photosensor from reaching saturation during operation of the time-of-flight camera.
