  • Papermaking belts having offset openings, papermaking processes using belts having offset openings, and paper products made therefrom
    Patent number: 11578460
    Abstract: A belt for creping a web in a papermaking process. The belt includes a surface onto which the web is transferred during the papermaking process. A plurality of openings extend through the surface, with the openings being arranged in lines that are offset from lines in the machine direction (MD) and cross-machine direction (CD) of the belt. Paper products, such as absorbent sheets, made from the belt have hollow dome regions and connecting regions between the domes, with the domes being arranged in lines that are offset from lines in the MD and CD of the paper products.
    Type: Grant

  • Multilayer creping belt having connected openings, methods of making paper products using such a creping belt, and related paper products
    Patent number: 11559963
    Abstract: An absorbent sheet made by a process that includes the steps of forming a nascent web from an aqueous papermaking furnish, and creping the nascent web on a multilayer belt that includes (i) a first layer made from a polymeric material having a plurality of overlapping openings, and (ii) a second layer attached to the first layer, with the nascent web being deposited onto a surface of the first layer. The absorbent sheet includes a plurality of hollow domed regions projecting from a side of the absorbent sheet.

  • Detection of variation in load impedance of wireless communications devices
    Patent number: 11381328
    Abstract: Systems, methods, and devices detect variations in load impedances of wireless communications devices. Methods include determining a first distortion measurement of a transceiver based on a first comparison of a digital loopback path and a radio frequency (RF) loopback path, and determining a second distortion measurement of the transceiver based on a second comparison of the digital loopback path and the RF loopback path. Methods also include implementing, using a processor, a third comparison of the first distortion measurement and the second distortion measurement, and determining if there is a change in a load of the transceiver based on the third comparison.
