    Abstract: In some examples, an electronic device comprises a processor and a power circuit coupled to the processor. The power circuit is to provide power to the processor and to measure a current drawn from the power circuit by the processor. The electronic device also comprises a voltage regulator controller coupled to the processor and the power circuit. The voltage regulator controller is to receive a current usage prediction from the processor, receive the measurement from the power circuit, compare the current usage prediction and the measurement, and, based on the comparison, drive the power circuit in accordance with the measurement instead of the current usage prediction.

    Abstract: The present specification describes examples of position-based switching of display devices. An example augmented reality (AR) device includes an AR display device to render display data. The example AR device also includes a wireless communication device to transmit and receive wireless signals. The example AR device further includes a processor to: 1) determine a position of the AR device relative to a computing device based on wireless signals communicated with the computing device; and 2) switch an activity state of the AR display device based on the determined position of the AR device relative to the computing device.

    Abstract: Examples of the present disclosure are directed toward fusing agent compositions. An example fusing agent composition includes a radiation absorber, a co-solvent mixture, and a balance of water. In various examples, the radiation absorber is present in an amount ranging from about 0.005 weight percent (wt %) to about 1.0 wt % of a total weight of the fusing agent composition, wherein the radiation absorber absorbs radiation at a wavelength range within the visible light spectrum.

    Abstract: Examples include an apparatus comprising a media path assembly for a printer. The assembly comprises a transmission module configured to be connected to a first motor of the printer and a first roller connected to the transmission module. The first roller is driven by the first motor through the transmission module when pulling a continuous sheet from a roll around a spindle of the printer in a forward direction towards a print zone of the printer. The transmission module is configured to be connected to a second roller of the printer, the second roller being driven by the first motor through the transmission module when pulling a cut sheet from a cut sheet tray of the printer in a forward direction towards the print zone.
