In one example of the disclosure, subject audio data, indicative of a subject audio captured via a transducer during an operation of a subject electromechanical device, is accessed. Baseline audio data, indicative of a baseline audio captured during an operation of a baseline electromechanical device, is accessed. An electronic file that includes differences between the subject audio data and the baseline audio data is created.

Audio data compression

In one example, an integrated circuit device for a replaceable printer component to communicate information about the component to a printer controller when a component with the integrated circuit device is installed in a printer. The integrated circuit device includes a controller, a memory operatively connected to the controller to store and/or generate information about the component, a single pair of conductors to supply power to the controller and to carry data signals to and from the controller, a detector to detect incoming data signals with a signal property associated with the component, and two electrical contacts each connected to one of the conductors to connect the integrated circuit device to a printer controller when a component with the integrated circuit device is installed in a printer.

Integrated circuit device for a replaceable printer component

In one example, an article for a replaceable printer component includes an integrated circuit device having a device controller, a conductor to supply power to the device controller and to carry a signal to and from the device controller, and a sensor operatively connected to the device controller to sense a voltage and/or a frequency on the conductor. The device controller to send an indication of a sensed voltage and/or a sensed frequency to the printer controller.

An example device includes a physical interface to connect to a system. The device also includes a power source to deliver power to a diagnostic portion of the system via the physical interface. The diagnostic portion draws a small amount of power. The power source delivers the power based on the system not receiving power from an internal source. The device also includes a reporting engine to communicatively couple to the system via the physical interface. The reporting engine retrieves an indication of whether a cable in the system is connected.

Detection of cable connections

Device

Apparatuses, systems, and methods are provided for processing data. In one method embodiment, the method includes defining a number of color channels, each channel to transfer a particular color element of a stream of color type pixel data. The method can also include identifying monochrome type pixel data within a data stream and allocating a color channel to transfer the identified monochrome type pixel data.

Monochrome and color transfer

An embodiment of a bus management device permits scheduling of transactions to allow concurrent execution of the transactions. Data bus usage is scheduled by setting shift register bits. Each position in the shift register corresponds to one clock cycle. When a current transaction is in a data phase, the value in the shift register is used to determine when to begin a control phase of the next transaction so that a desired number of idle clock cycles are present between data bus usage time periods for successive transactions.
