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

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.

In an example, a method comprises, by logic circuitry associated with a replaceable print apparatus component, responding to a first validation request sent via an I2C bus to a first address associated with the logic circuitry with a first validation response; and responding to a second validation request sent via the I2C bus to a second address associated with the logic circuitry with a second validation response.

In an example, a method includes, by logic circuitry associated with a replaceable print apparatus component installed in a print apparatus, responding to a sensor data request received from the print apparatus by returning a first response; receiving a calibration parameter from the print apparatus; and returning a second response which is different from the first response.

Logic circuitry for sensor data communications

A logic circuitry package for a replaceable print apparatus component includes an interface and at least one logic circuit. The at least one logic circuit is configured to respond to communications sent to a first address via the interface and respond to communications sent to a second address via the interface. The at least one logic circuit is configured to in response to a hibernate command sent to the first address, respond to communications sent to the second address.

Logic circuitry package

A logic circuitry package for a replaceable print apparatus component includes an interface to communicate with a print apparatus logic circuit, and a logic circuit having a communication address to communicate with the print apparatus logic circuit. The logic circuit is configured to detect, via the interface, communications that include an other communication address. The logic circuit is configured to respond, via the interface, to a command series directed to the logic circuit that include the communication address of the logic circuit, based on the detected communications.

A logic circuitry package includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit. The logic circuit is configured to receive, via the interface, a plurality of first requests in a heater disabled mode, each first request corresponding to a different sensor ID of a plurality of sensor IDs; transmit, via the interface, a first digital value in response to each first request; receive, via the interface, a plurality of second requests in a heater enabled mode, each second request corresponding to a different sensor ID of the plurality of sensor IDs; and transmit, via the interface, a second digital value in response to each second request. Delta values corresponding to a difference between the first digital value and the second digital value for each different sensor ID of the plurality of sensor IDs are indicative of a print material level.

This disclosure describes integrated circuits which may be provided in logic circuitry packages and/or replaceable print apparatus components with print material reservoirs. An integrated circuit or 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.

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.

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.

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.

An embodiment of an auscultation device can be constructed using electronic components to provide improved acquisition, processing, and communication of sound signals. An input device can be used for detecting sounds, and electrical signals representing the sounds can be processed and transmitted via Bluetooth and/or another form of wireless communication. Such embodiments can employ, at least in part, one or more of several commercially available wireless receiver devices, such as, without limitation, headsets and headphones, mobile phones, PDAs and/or other handheld devices, desktop, laptop, palmtop, and/or tablet computers and/or other computer devices and/or electronic devices.
