    Abstract: A three-dimensional printing kit can include a particulate build material including from about 80 wt % to about 100 wt % metal particles, a binder fluid including water and latex particles in an amount of from about 5 wt % to about 30 wt % based on a total weight of the binder fluid, and an amine-bearing phosphonic adhesion promoter included in the binder fluid in an amount of from about 0.05 wt % to about 3.5 wt % based on a total amount of the binder fluid, or a separate adhesion promoter fluid in an amount of from about 0.1 wt % to about 5 wt % based on a total amount of the adhesion promoter fluid.

    Abstract: An example apparatus may include a hardware component, a memory, and a processor. The processor may retrieve a firmware for the hardware component subsequent to the firmware being loaded on the hardware component. The processor may determine that a firmware signature associated with the firmware is stored in the memory. In some examples, in response to a determination that the firmware signature associated with the firmware is stored in the memory, the processor may initiate authentication of the firmware.

    Abstract: An example computing device comprises a memory to store control instructions, and a processor to: perform a first authentication of the control instructions using a first key; and in response to receipt of a command to enable a second authentication of the control instructions, add a second key to a one-time programmable portion of the memory, wherein the command is signed using the first key, the second key to perform a second authentication of the control instructions with the first key to perform the first authentication of the control instructions.

    Abstract: A method may include obtaining, using a head detection model and for an image of a video stream, head detection information, where the head detection information identifies heads detected in the image. Method may also include obtaining buffer bounding boxes. Obtaining the buffer bounding boxes may include obtaining head buffer bounding boxes for the heads detected in the image, and combining at least two of the head buffer bounding boxes into a proximity buffer bounding box. The method may furthermore include identifying a set of templates based on the buffer bounding boxes. Method may in addition include creating, individually, head frame definitions for the buffer bounding boxes using the set of templates, generating an image frame definition that combines the head frame definitions, and processing the video stream using the image frame definition.

    IPC: G06F1/26

    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.
