Abstract: Methods, apparatuses, and computer readable media for communicating elements between multi-link devices are disclosed. Apparatuses of a first access points (AP) of an AP multi-link device (MLD) are disclosed, where the apparatuses comprise processing circuitry configured to encode a first portion of a first beacon frame or first response frame, and in response to a second AP of the AP MLD transmitting, on a second frequency band, a second beacon frame or a second probe response frame comprising a channel switch announcement element or an enhanced channel switch announcement frame, encoding a second portion of the first beacon frame or the first probe response frame, the second portion comprising the channel switch announcement element or the enhanced channel switch announcement frame. The processing circuitry is further configured to configure the first AP of the AP MLD to transmit, on a first frequency band, the first beacon frame.

Abstract: A machine suitable for placement in a freezer for making slush or ice cream in a cylindrical container. The machine comprises a platform which is lengthwise adjustable, at least four rollers which have an adjustable distance support container, a driving means to drive the rollers and rotate the container, a scraping means disposed on the shaft of the container to scrape freezing slush or ice cream and to be used as a second safety means, and a first safety means which comprises a base plate, a control plate and a flexible element engaged together. When the slush or ice cream is hard enough, the control plate and the flexible element will rotate respective to the base plate so that the shaft will rotate together with the container. Further, even if the first safety means is out of order, the scraping means will free from the shaft of the container, then the scraping means will rotate together with the container in order to be used as a second safety means.
