Abstract: An example storage medium is described, wherein the storage medium comprises instructions that, when executed, cause a processor of an electronic device to determine whether data private key is stored in a first memory of the electronic device and whether a network connection is available. If the private key is stored and no network is available, emulated responses of a networked service are generated for decryption of data in the electronic device.

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.
