  • Patent number: 12253623
    Abstract: Example embodiments relate to corrugated radomes for protecting and concealing components of radar units. An example radar system may include a radar unit that includes at least one antenna having a radiation pattern. The radar unit is configured to transmit a radar signal based on the radiation pattern and receive radar signals. In addition, the radar system further includes a radome located in a direction of transmission of the radiation pattern. Particularly, the radome includes a stepped surface having at least one step that includes a height equal to one-quarter of a wavelength at a frequency of operation of the radar unit. The least one step is positioned on the radome such that the at least one step causes deconstructive interference of reflections of the transmitted radar signal caused by the radome.

  • Patent number: 12225629
    Abstract: A wireless device system can include lighting devices, sensing devices, and other wireless devices in a wireless mesh local area network. The devices are configured for rapid provisioning with provisioned site network data by using a process in which each device stores data for a default provisioning network, and a provisioning device, for example a smart phone or other mobile device, is used to wirelessly connect with at least one of the devices in the default provisioning network, enabling distant wireless devices to be reached by relay of messages in the default provisioning network. Devices can be individually provided a new network address, for example, from the provisioned site network data, and all devices are provided remaining data from the provisioned site network data using the mesh network broadcast feature, thus provisioning and switching devices near simultaneously from the default provisioning network to the provisioned site network.

  • Publication number: 20240399224
    Abstract: In a flat roll-up structure for rolling up net body flatly, at upper and lower end of net body, it is installed respectively with protruding object, meanwhile, at roll-up mechanism, it is installed with upper and lower positioning roller module to limit the movement scope of net body, therefore, when net body is to be expanded, net body, through the guidance of upper and lower positioning roller structure, can be withdrawn flatly; when protruding object used to roll up net body is limited for its movement scope by upper and lower positioning roller module, and is limited by the limiting part of upper and lower positioning roller module, the net body can then be rolled up flatly without generating up and down shift, which can avoid the generation of tying problem due to unbalanced receiving in net body.
