  • Logic circuitry
    Patent number: 10894423
    Abstract: A logic circuit for a replaceable print component is configured to, in response to a plurality of commands including a first command specifying the new I2C communications address and a first calibration parameter, a second command specifying the new I2C communications address and a second calibration parameter, a third command specifying the new I2C communications address and a class parameter, and/or fourth commands specifying the new I2C communications address and sub-class parameters, and at least one read request, generate count values in a count value range defined by a highest and lowest count value.
    Type: Grant
    Filed: July 3, 2019
    Date of Patent: January 19, 2021
    Assignee: 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
  • LOGIC CIRCUITRY
    Publication number: 20210001635
    Abstract: In an example, a logic circuit comprising a communications interface including a data contact to communicate via a communications bus, an enablement contact, separate from the communication interface, to receive an input to enable the logic circuit, and at least one memory register, comprising at least one reconfigurable address register. The logic circuit may be configured, such that, when enabled, it responds to communications sent via the communication bus which are addressed to the address held in a reconfigurable address register.

  • Logic circuitry
    Patent number: 10875318
    Abstract: A sensor circuit for a replaceable print material container to be connected to a host print apparatus logic circuit comprising a first sensor to detect a pneumatic stimulus or pressurization applied by a print apparatus, and an interface including contact pads to connect to a voltage and/or data source of the print apparatus logic circuit, the sensor circuit configured to output signals conditioned by the pneumatic stimulus or pressurization via the contact pads.
