Abstract
A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and at least one logic circuit to receive, via the interface, requests corresponding to different sensor IDs with the component connected to the apparatus. The logic circuit is to transmit, via the interface, a digital value in response to each request. The digital values corresponding to the different sensor IDs are distinct.

A logic circuitry package for a replaceable print apparatus component comprising an interface to communicate with a print apparatus logic circuit, and at least one logic circuit configured to:
- receive, via the interface, requests corresponding to different sensor IDs with the component connected to the apparatus;
- and
- transmit, via the interface, a digital value in response to each request;
- wherein the digital values corresponding to the different sensor IDs are distinct.
A logic circuitry package for a replaceable print apparatus component comprising an interface to communicate with a print apparatus logic circuit, and at least one logic circuit configured to:
- receive, via the interface, initial requests to read sensor IDs with the component connected to the apparatus and the apparatus not pneumatically actuating the component;
- transmit, via the interface, a resting state digital value in response to each initial request;
- receive, via the interface, first actuated state requests corresponding to the sensor IDs with the component connected to the apparatus and the apparatus pneumatically actuating the component at a predetermined pressure;
- and
- transmit, via the interface, a first actuated state digital value in response to each first actuated state request;
- wherein delta values corresponding to a difference between the first actuated state digital value and the resting state digital value for each sensor ID are distinct.
A logic circuitry package for a replaceable print apparatus component comprising an interface to communicate with a print apparatus logic circuit, and at least one logic circuit configured to:
- receive, via the interface, initial requests to read a first sensor ID and a second sensor ID with the component connected to the apparatus and the apparatus not pneumatically actuating the component,
- transmit, via the interface, a resting state digital value in response to each initial request;
- receive, via the interface, first actuated state requests corresponding to the first sensor ID with the component connected to the apparatus and the apparatus pneumatically actuating the component;
- transmit, via the interface, a first actuated state digital value in response to each first request;
- receive, via the interface, second actuated state requests corresponding to the second sensor ID with the component connected to the apparatus and the apparatus pneumatically actuating the component;
- transmit, via the interface, a second actuated state digital value in response to each second request;
- wherein first delta values corresponding to a difference between each first actuated state digital value and the resting state digital value for the first sensor ID are distinct,
- wherein second delta values corresponding to a difference between each second actuated state digital value and the resting state digital value for the second sensor ID are distinct, and
- wherein the first delta values are different from the second delta values.
The logic circuitry package of claim of 52, wherein the dynamic signature comprises a first predetermined function that corresponds to the first delta values and a second predetermined function that corresponds to the second delta values.
