Patent number: 11738562Abstract: A logic circuitry package for a replaceable print apparatus component comprises an interface to communicate with a print apparatus logic circuit, and at least one logic circuit. The logic circuit may be configured to identify, from a command stream received from the print apparatus, parameters including a class parameter, and/or identify, from the command stream, a read request, and output, via the interface, a count value in response to a read request, the count value based on identified received parameters.Type: GrantFiled: July 14, 2022Date of Patent: August 29, 2023Assignee: Hewlett-Packard Development Company, L.P.Inventors: James Michael Gardner, Scott A. Linn, Stephen D. Panshin, Jefferson P. Ward, David Owen Roethig, David N. Olsen, Anthony D. Studer, Michael W. Cumbie, Sirena Chi Lu

Patent number: 10940693Abstract: Disclosed herein are sensor circuits for a replaceable print material container, the sensor circuit to communicate with a printer logic circuit. An example sensor circuit includes a first sensor to detect at least one of a pneumatic stimulus or a pressurization applied by a printer, a second sensor, and an interface to communicate with at least one of a voltage source or a data source of the printer logic circuit. The example sensor circuit also includes logic circuitry, responsive to a class parameter, to: (a) output a first signal based on at least one of the pneumatic stimulus or the pressurization sensed by the first sensor when the class parameter is a first class parameter; and (b) output a second signal based on at least one of an output of the second sensor, different data, or a different algorithm when the class parameter is a second class parameter.Type: GrantFiled: December 27, 2019Date of Patent: March 9, 2021Assignee: Hewlett-Packard Development Company, L.P.Inventors: James Michael Gardner, Scott A.
