摘要： A capacitance detection device includes a first electrode and a second electrode that at least partially face each other on opposite sides of a transfer path. An oscillator circuit forms an electric field between the first electrode and the second electrode. A detection circuit detects a change in capacitance between the first electrode and the second electrode. At least one of the oscillator circuit and the detection circuit is included in each of a first board and a second board. The first board is disposed such that a side surface of the first board faces the first electrode in an electric field direction, and the second board is disposed such that a side surface of the second board faces the second electrode in the electric field direction.

摘要： The invention relates to a method and a measuring arrangement for detecting an object (3) hidden behind an article (1). The method comprises the following steps: applying a first alternating voltage (5) to a first sensor (7); applying a second alternating voltage (9) to a second sensor (11) arranged adjacent to the first sensor (7); determining an effect (15) of the article (1) on at least one of the alternating voltages (5, 9) depending on a distance (13) of the sensor (7, 11) to the article (1); determining a change (17) in the dependent effect (15) occurring during a movement (19) of the sensor (7, 11) along the article (1); and detecting the object (3) in accordance with the change (17) of the dependent effect (15). In this way, a detection of an object hidden behind an article is improved such that the object can be recognized as independently as possible from a relative position of the device to the article, in particular, an angular position, in particular also if the device for detecting the object is manually moved beyond the article.

摘要： Provided is a detection circuit that has a first inductor connected to two opened input ends and detects an external signal having a waveform with a gradient at each input end. The detection sensor further includes an output circuit that has a second inductor magnetically coupled with the first inductor as a primary side. In the output circuit, a third inductor constituting a delay circuit having one end connected to an intermediate tap of the second inductor is connected. Diodes are respectively connected to terminals of the second inductor in a forward direction. Other terminals of the diodes are connected to another terminal of the third inductor via elements each having an impedance characteristic. The output circuit outputs a detection signal detected at the input ends, from the other terminal(s) of at least one of the diodes.

摘要： The disclosure relates to a method of detecting an object using a detection signal supplied by a proximity sensor. The method comprises the steps of generating a reference signal by filtering the value of the detection signal, defining a first detection threshold, and going from an object non-detecting state to an object detecting state when the value of the detection signal becomes greater than the first detection threshold. When the value of the detection signal becomes greater than the first detection threshold, the value of the reference signal is readjusted in a manner such that the value of the detection signal again becomes less than or respectively greater than, the first detection threshold.

摘要： A positioning device for capacitively detecting an object enclosed in a medium includes a measuring electrode, a reference electrode, and a receiving electrode. The measuring electrode with the receiving electrode forms a measuring capacitance, which can be influenced by the object. The reference electrode with the receiving electrode forms a reference capacitance, which cannot be influenced by the object. The positioning device further includes an oscillator configured to supply the measuring capacitance and the reference capacitance with phase-shifted AC voltages and a control device configured to control amplitudes of at least one of the AC voltages, in order to adapt effects of electrical fields of the measuring electrode or of the reference electrode on the receiving electrode to one another. The measuring, reference, and receiving electrodes are planarly formed. The measuring electrode has a larger surface area than the reference electrode.

摘要： A system and method for incorporating occupancy-detecting technology into furniture is provided. More particularly, the invention relates to detecting occupancy in a recliner using a sinuous wire detection array incorporated into a seat. Further embodiments of the invention are directed to a system and method for incorporating capacitance detection technology with one or more conductive features of a recliner mechanism. In some aspects, a sensor is provided based on coupling one or more conductive features to a control component of the capacitance detector control component. A controller may determine the corresponding response based on occupancy detection and/or presence detection. A processor may receive information regarding changes in capacitance and determines when a change in voltage satisfies a threshold. Based on a determination of occupancy and/or presence, a variety of corresponding features of the adjustable recliner may be activated.
