Abstract: According to examples, an apparatus may include a first hardware component including a first memory and a first processor. The first processor may initiate pairing between the first hardware component and a second hardware component to establish a trusted relationship between the first hardware component and a second hardware component. In response to a successful pairing between the first hardware component and the second hardware component, the processor may compare a first setting of the first hardware component with a second setting of the second hardware component.

Abstract: Examples described herein relate to systems and methods consistent with the disclosure. For instance, the system may comprise a processing resource, and a non-transitory machine-readable medium storing instructions executable by the processing resource to send an identification code to a server to initiate a system configuration, receive a payload including a configuration instruction responsive to the sent identification code, configure the system utilizing the payload including the configuration instruction, where the system is permanently configured, and store a receipt including the payload responsive to the configuration of the system.

Abstract: One example discloses a method for calibrating an imager. A plurality of images of a target, each having an associated integration time, are captured at the imager. A representative digital count is determined for each of the plurality of images. Integration time is represented as a function of digital count from the respective digital counts and integration times associated with the plurality of images. A calibrated integration time is calculated from a target digital count.
