Publication number: 20250350503Abstract: This disclosure relates to joint communications and sensing. A system is disclosed and comprises a first AP as a sensing AP, a second AP as a communications AP, and a network device as a controller. The communications AP and the sensing AP both receive an uplink signal from a UE. The communications AP is configured to send a processed form of the signal to the controller. The controller then provides the processed form of the signal (e.g. the decoded payload) to the sensing device. The sensing AP performs channel estimation based on the processed form of the signal and the received uplink signal. A result of the channel estimation may be provided by the sensing AP to the controller for monitoring the UE or the environment. In this way, sensing with zero wireless communications cost can be achieved.Type: ApplicationFiled: July 22, 2025Publication date: November 13, 2025Inventors: Mahdi SHAKIBA HERFEH, Yun Yaw CHU, Mohamed KAMOUN, Sami MEKKI, Stefano BUZZI

Publication number: 20190151067Abstract: An arrangement for storage of a self-expanding stent-like device includes a container for storing the stent-like device and a stent delivery system arranged at the container and including an outer tube and an inner shaft axially moveable relative to the outer tube. The container includes an interior space and one stent passage opening. A distal end of the outer tube is connected to the stent passage opening. An insertion part of ring-like shape is located at the stent passage opening. The inner shaft extends through the insertion part and includes a retainer to prevent the stent-like device from axial movement relative to the inner shaft. When the stent-like device is stored in the interior space of the container, a proximal end of the stent-like device is compressed to a diameter smaller than a diameter of the insertion part and is held radially compressed by the insertion part.Type: ApplicationFiled: May 9, 2017Publication date: May 23, 2019Applicant: Qvanteq AGInventors: Arik ZUCKER, Armin W.
