The invention relates to a control unit (10) for an electrical apparatus, in particular a vehicle component such as, for example, a heating, ventilation and/or air conditioning installation, which is provided with a housing (12) having a front wall (14), with a control strip (18) that projects beyond the front wall (14), which has an elongated control surface (20) with a plurality of adjacently arranged control fields (22, 24, 26, 28, 30), and with a support element (32) for the control strip (18), which is arranged in the housing (12). The control strip (18) is connected to the support element (32) by means of connecting webs (48) which protrude in the respective areas between the control panels (22, 24, 26, 28, 30) of the control strip (18). Flexible webs (50), which protrude from the control strip (18) for each operating field and are connected to the support element (32), are arranged between the connecting webs (48), namely in an elastic manner and more flexible than the connections of the control strip (18) to the support element (32) via the connecting webs (48). At least one control field actuation sensor (70, 72) for detecting a local bending of the control strip (18), when a manual actuating force is exerted on a control field (22, 24, 26, 28, 30) of the control strip (18), is arranged on the support element (32) for each flexible web (50). In addition, the control unit (10) comprises an evaluation and control unit (78) for receiving the signals of the control panel actuating sensors (70, 72) and for determining, on the basis of said signals, the control field (22, 24, 26, 28, 30) on which, upon manual actuation of the control strip (18), the finger of one hand is applied, and for triggering an apparatus function that is associated with the respective control field (22, 24, 26, 28, 30) corresponding to the determined control field (22, 24, 26, 28, 30).

The description relates to a control circuit for recording the actuation of an optical key, in which there is a light-sensitive diode operated in open circuit as a key actuation sensor. A microprocessor circuit monitors the no-load voltage of the diode to differentiate an actuation of the optical key from variations in the brightness of the ambient light. The invention is characterized by an easily producible voltage-time-conversion process for monitoring the no-load voltage. To this end, there is a capacitor connected to the diode which assumes a load operating status corresponding to the no-load voltage of the diode and can be discharged in a discharge operating status via a discharge resistor, where the microprocessor circuit has a high-resistance input port connected to the capacitor to monitor the capacitor discharge and, as a measure of the no-load voltage, determines the time elapsing until the voltage at the input port during the capacitor discharge process reaches a predetermined input port switching threshold.

The invention relates to a display device (10) of a motor vehicle, comprising at least one display element (12, 20, 28, 30, 32), by means of which at least one value can be displayed and which has at least one illumination element for adjusting the display luminosity of the display element (12, 20, 28, 30, 32). The display device also comprises at least one piece of detection equipment comprising at least one detection element (38) for detecting the ambient luminosity surrounding the display element (12, 20, 28, 30, 32), the display luminosity being adjustable by means of the illumination element in accordance with the detected ambient luminosity. When a change in the ambient luminosity is detected, the detection equipment is designed to effect at least one function in the motor vehicle that is different from the adjustment of the display luminosity. The invention also relates to a method for operating a display device (10) of this type.

Ein Bedienfeld für ein elektronisches Gerät, insbesondere Haushaltsgerät, enthält mehrere Bedienelemente (10, 12) zum Eingeben von Stellwerten in eine Steuerung (µC) des elektronischen Geräts und eine Anzeigeeinheit zum Anzeigen von eingegebenen Stellwerten und/oder anderen Informationen, wobei die mehreren Bedienelemente (10, 12) fortlaufend im Wechsel freigegeben werden. Die mehreren Bedienelemente (10, 12) weisen wenigstens ein Bedienelement einer ersten Art (10) und wenigstens ein Bedienelement einer zweiten Art (12) auf, wobei das wenigstens eine Bedienelement der zweiten Art (12) ein Berührungsschalter mit einem digitalen (High/Low-)Ausgangssignal ist und zwischen die Steuerung und das Bedienelement der zweiten Art (12) eine Transistorschaltung (16) geschaltet ist, welche das Schaltverhalten des Bedienelements der zweiten Art (12) an das Schaltverhalten des wenigstens einen Bedienelements der ersten Art (10) adaptiert. Auf diese Weise können Bedienelemente der zweiten Art (12), wie beispielsweise kapazitive Berührungsschalter, in bereits bestehende Bedienfelder beispielsweise ausschließlich mit Infrarot-Sensoren (10) integriert werden.

The invention relates to a device and method for evaluating a useful signal U(t) originating from a proximity sensor. The device comprises a first recognition means (17) which changes the switching state thereof when the value (U1(t)) of a first signal produced from the useful signal exceeds a first limit value that characterizes the proximity of an object. In addition, a second recognition means (34) is provided which changes the switching state thereof from a first to a second state when the value (U(t)) of the useful signal exceeds a second limit value that characterizes the removal of an object. A decision means (32), which is connected to the first recognition means (17) and to the second recognition means (34), changes its switching state when the first recognition means (17) changes the switching state thereof from its first to a second switching state, and the second recognition means does not change the switching state thereof during a predetermined first time span (Δt1) after the switching state of the first recognition means is changed.
