Patent number: 11150147Abstract: A woven fabric includes first and second woven fabric layers with an intermediate layer in between, which form a sensor with an electrical characteristic that changes while a force is acting on the woven fabric. The first layer includes electrically conductive strips and electrically non-conductive strips arranged adjacent to one another in an alternating manner. The second layer includes alternating conductive strips and non-conductive strips that extend transverse to the strips of the first layer. At least some of the threads in each of the conductive strips of the first layer are conductive weft threads. At least some of the threads in each of the conductive strips of the second layer are conductive weft threads. The non-conductive strips of the first and second layers are weft threads.Type: GrantFiled: September 19, 2018Date of Patent: October 19, 2021Assignee: Pilz GmbH & Co.

Patent number: 11112317Abstract: A safety device for monitoring a technical installation with a pressure-sensitive sensor. The pressure sensitive sensor having a plurality of first and second electrodes, wherein each first electrode overlaps each second electrode in an associated coupling site. Furthermore, each first electrode is spaced apart from the associated second electrode in the associated coupling site by a pressure sensitive material. Upon application of a force at the coupling site, an electrical resistance between the associated first and second electrode changes. A measuring circuitry coupled to said plurality of first and second electrodes successively determines the electrical resistance at associated coupling sites. For determining the electrical resistance at a coupling site via the associated first and second electrode, the measuring circuitry connects the further first and second electrodes to a terminal for receiving a defined potential to enable isolated measurement of the electrical resistance at the coupling site.Type: GrantFiled: January 23, 2019Date of Patent: September 7, 2021Assignee: Pilz GmbH & Co.

Patent number: 10350764Abstract: A sensor assembly comprising first, second and third layers of flexible material forming, when superposed, a pressure-sensitive sensor having at least two sensor cells. The first layer comprises first and second electrically conductive regions mechanically connected to each other via an electrically non-conductive region. The second layer comprises a third electrically conductive region.
