Abstract: An example electronic device includes a network communication interface to connect to a conference server, a central control device communication interface to connect to a local central control device, a microphone and a processor. The processor is to receive audio at the microphone and send the audio to the local central control device and to the conference server. The processor is to send the audio to the local central control device such that it is received by a nearby electronic device before the audio is received from the conference server by the nearby electronic device.

Abstract: In some examples, an electronic device includes a port and a controller. The controller compares an encrypted identifier received via a side-band communications channel of the port to a trusted identifier retrieved from a storage device. Responsive to the encrypted identifier being equivalent to the trusted identifier, the controller compares an encrypted user credential received via the port to a trusted user credential retrieved from the storage device. Responsive to the encrypted user credential being equivalent to the trusted user credential, the controller enables a user access to the electronic device.

Abstract: In an example of the disclosure, a system to service a print blanket includes a rotatably mounted endless cleaning surface (“ECS”), a doctor blade, a heating element, and a container. The ECS is to carry a polymeric material and positioned to engage the print blanket. The doctor blade is disposed in relationship to the ECS and to a container to scrape a portion of the polymeric material from the ECS into the container. The heating element is to heat the container. The container is positioned to collect the scraped portion of polymeric material, and make heated polymeric material available to be picked up by the ECS as the ECS is rotated adjacent to the container.

Abstract: A logic circuitry package includes a logic circuit and an interface to communicate with a host logic circuit. The logic circuit includes a memory arrangement storing an asymmetric key, and/or a certificate corresponding to the asymmetric key. The logic circuit is configured to transmit, to the host logic circuit, the certificate; receive, from the host logic circuit, a static signature request comprising challenge data; and/or, transmit, to the host logic circuit, a signature computed based on the challenge data and the asymmetric key in response to the static signature request.
