Publication number: 20220398534Abstract: A cargo space is monitored for objects connected to respective beacon-transmitting devices which transmit identification signals associated with the objects. Signal strengths of received signals and repetition periods associated therewith are determined using a monitoring device which checks whether each received beacon identification signal identifies a respective object in an object inventory of the cargo space based on comparisons of the signal strengths with current signal strength threshold values respectively associated with them and on comparisons of the respectively associated beacon repetition periods with respective current repetition period threshold values. The monitoring device detects whether the cargo space is currently in a first state (in which loading and unloading operations of objects in the cargo space is permissible) or a second state (in which loading and unloading is not permissible).Type: ApplicationFiled: May 16, 2022Publication date: December 15, 2022Inventors: Detlef Kuck, Marcel Grein, Nicole Eikelenberg, Walter Pijls, Jörg Christian Kirchhof

Patent number: 9226348Abstract: A light-emission device with a two-dimensional OLED element and an encapsulation element for protecting the OLED element. The light-emission device furthermore has a support, on which the OLED element is arranged in such a way that the encapsulation element points toward the support, and an electrical conductor element for an electrical connection between the support and the OLED element. wherein the electrical conductor element is elastic in a normal direction to the OLED element. By way of example, the conductor element can be helical. As a result of the elastic property thereof, the conductor element can absorb mechanical tension while ensuring reliable electrical contacting. Hence, this can reduce or even avoid the risk of the electrical connection between the support and the OLED element being disadvantageously influenced or impaired by forces which can occur when handling the light-emission device or which can be generated by temperature variations.Type: GrantFiled: April 2, 2013Date of Patent: December 29, 2015Assignee: TRODONIC GMBH & CO.
