The invention also relates to a switch device, especially a switch device on a capacitive basis, for a cooktop, for operating the cooktop. | 07-14-2011 |
| 20100194209 | APPLIANCE SAFETY SYSTEM FOR PROTECTED OPERATION OF DANGEROUS MOTOR APPLIANCES, ESPECIALLY GARDENING APPLIANCES AND TOOLS - The invention relates to a system for protected operation of dangerous motor appliances, especially gardening appliances, such as hedge or edge clippers, power saws and lawnmowers. The object of the invention is to provide solutions by which advantages in terms of operating safety are achieved during operation of motor appliances, especially hand-held gardening and forestry appliances as well as power tools. In an initially abstract description, this object is achieved according to the invention by an appliance safety system for averting dangerous operating situations in the use of motor-powered appliances. This system comprises field-preparing means for generating a capacitive spatial alternating field and detecting means for detecting a condition that can be classified as dangerous and/or shutdown by detecting relevant electric-field effects during penetration of an object into the zone being sensed by each field. | 08-05-2010 |
| 20100044120 | INPUT DEVICE - The invention relates to an input device for a user to perform switching, control and other input and selection operations. Input devices of this type are known in particular in the form of switches, sliders and touch screens on electrical equipment and other controls, e.g. in the vehicle field. The object of the invention is to create solutions that make it possible to create with a large degree of freedom of design an input interface that is advantageous for a user, particularly one that is easy to operate intuitively. This object is attained according to the invention with an input device for providing an input surface for generating switching, control and other input and selection operations, according to an input operation performed by a user, with at least one input organ for forming an input point provided for the generation of that signal, and an evaluation circuit for detecting the input operation performed by the user near the input point, wherein the input organ is embodied such that it supplies a haptic feedback, and the evaluation circuit defines a detection zone in which the input organ is located. | 02-25-2010 |
| 20090066346 | DETECTION CIRCUIT DEVICE AND METHOD FOR DETECTING THE PRESENCE OF AN OBJECT IN THE VICINITY OF A MOTOR VEHICLE - The invention relates to a circuit device and a method for detecting the presence of an object in the vicinity of a motor vehicle. The aim of the invention is to provide solutions which allow monitoring the vicinity of a motor vehicle with regard to the presence of an object. In particular, the aim of the invention is to provide solutions which allow detecting the approach of human body parts to danger-relevant structures, such as for example soft top devices, window openings, door openings and trunk lids, and taking the appropriate safety measures. According to the invention, this problem is solved by a motor vehicle that comprises a detection circuit with a first electrode system, a second electrode system and an alternative current generator for generating a potential difference between the two electrode systems, the first electrode system being arranged in the lower region of the vehicle for inputting the shift current events in the region supporting the vehicle. The detection circuit further comprises an evaluation device by means of which a feedback of the shift current events in the second electrode system is determined via the object to be detected. | 03-12-2009 |
| 20090033342 | Sensor Device - The invention relates to a sensor device for producing signals that provide information as to whether an object, especially the limbs of a person, are present in an area of observation. The aim of the invention is to provide a sensor device which allows generation of measuring signals that have high informative value with respect to the presence of an object in an area of observation. For this purpose, a sensor device comprises a support structure extending along an area of observation. A plurality of detection sections is configured one after the other on the support structure for detecting detection events in the zone of observation defined by the respective detection section. The invention provides a monitoring circuit which allows an area of observation, extending along a boundary zone of some length, subdivided into small sections, for example a closing edge, to be monitored in an especially precise manner. | 02-05-2009 |
| 20080204117 | Electrical Circuit Arrangement - The invention relates to an electrical circuit arrangement for generating signal events for initiating or carrying out switching, adjusting or releasing processes. According to the first invention aspect, the inventive electric circuit arrangement comprises an input component for carrying out a selection process for generating an input event and a switching component for generating a switching signal according to the input event evaluation, wherein said input component is constructed in such a way that, in framework of said selection process, the input event is injected into the user actuating the switching component on the base of the interactive effect of electric fields and said switching component is provided with an interface device for detecting the input event injected into the user or acting therein, the input component and the interface device are placed in the operating position in such a way that the signal transmission therebetween is carried out in a signal transmission path integrating the user when it actuates the input component, thereby making it advantageously possible to transmit the user input operation indicative signals to the switching component through said user, wherein said transmission can be carried out only when the user actually initiates an input and thereby can be used in the form of a signal transmitting medium. | 08-28-2008 |
