20100063421 | SENSOR APPARATUS AND METHOD FOR GENERATING SIGNALS INDICATIVE OF THE POSITION OR CHANGE IN POSITION OF LIMBS - The invention relates to a sensor apparatus and to a method for generating electronic signals which indicate a spatial position and/or the movement of limbs, particularly the hand of a user relative to the sensor apparatus. These electronic signals can then be used for carrying out input processes in data processing, communication and other electrical devices. The object of the invention is to create solutions by which signals indicative of the position and/or the movement of limbs can be generated in a particularly advantageous manner. This object is achieved by a sensor apparatus for generating electrical signals which indicate the position or movement of limbs relative to a reference area, the apparatus comprising a transmitter electrode apparatus, a voltage generator for applying an alternating voltage to the transmitter electrode, a first receiver electrode apparatus, a second receiver electrode apparatus, and a third receiver electrode apparatus, wherein the first, second, and third receiver electrode apparatuses are each connected to high-impedance tapping systems. The first, second, and third receiver electrode apparatuses are preferably each connected to high-impedance inputs of an impedance transformer system, wherein information indicative of a location or movement is obtained on the basis of differences between the electrical events present at the outputs of the respective impedance transformer. | 03-11-2010 |
20110012584 | SAFETY DEVICE, PARTICULARLY FOR HOUSEHOLD APPLIANCES - The invention relates to a safety system for detecting the presence of living beings inside a lockable, or alternatively dangerous housing area, particularly the washing housing area of a washing machine or of a clothes dryer, of a stove, of a microwave oven, as well as particularly also in closets and chests. According to a first aspect of the present invention the aim at the beginning is solved by means of a safety device for detecting the presence of living beings inside a dangerous housing area with a first electrode device which, as such, is facing the housing area and is a component of a LC network, and a second electrode device which is also facing the housing area and is a component of a LC network, and an evaluation circuit for detecting the dynamics of electric field interactions with at least one of the two electrode devices in which the detected dynamics is compared with the comparison values provided for the current working condition of the housing area, so that, if the detected dynamics differs from the provided comparison values, a safety function is activated. | 01-20-2011 |
20110241700 | CAPACITATIVE SENSOR DEVICE - A capacitive sensor device is provided, especially for determining a rotational frequency of a rotary body, for example of a washing drum and for detecting the amount and/or of the humidity grade of a laundry situated in the washing drum. | 10-06-2011 |
20110287838 | INPUT DEVICE - The invention relates to an input device for generating input signals, that as such correlate with the motion as well as the position of a user standing on a contact area. The present invention concerns an input device for generating input signals that as such correlate with the load of a contact area, with a contact area structure that constitutes a substantially horizontally oriented contact area, a foot structure that passes under that contact area structure and supports it as to a support area, a detection circuit for detecting detection events that correlate with the shifting of the. contact area structure as to the foot structure, in which the detection circuit comprises a first electrode device and a second electrode device and both these electrode, devices are operatively coupled with the contact area structure in such a way that during a change of the load of the contact area structure causes a change of the capacity correlated with this loading change of a capacitor system formed each time including the two electrode devices. | 11-24-2011 |
20120001647 | TOUCH AND APPROACH DETECTION WITH CAPACITATIVE SENSORS - Provided by the invention is a sensor device for the detection of touch or approach of an object. A server circuit of the sensor device according to the invention is formed in such a manner, that the server circuit alone (i.e. without co-operation with a client circuit) may be used as approaching sensor, at the same time however also together with one or several client circuits may be implemented a sensor network, in which the client circuits preferably are fed with energy with the electric field of the server electrode. | 01-05-2012 |
20120313852 | SENSOR SYSTEM FOR GENERATING SIGNALS THAT ARE INDICATIVE OF THE POSITION OR CHANGE OF POSITION OF LIMBS - The invention relates to a sensor device for generating electronic signals which as such provide information on a position in space, and/or the movement of limbs, especially of the hand of a user in relation to the sensor device.
