Interfacing with a one-wire device that is in parallel with a low-impedance element, and related systems and devices

A system, comprising:

• a replaceable module comprising:
• an element electrically coupled between a first line and a second line;
• and
• a one-wire authentication element electrically in parallel with the element between the first line and the second line;
• and
• a user device to operably couple to the replaceable module, the user device comprising:
• an authentication unit to perform a verification process for verifying authenticity of the replaceable module, and to permit operable coupling between the user device and the replaceable module responsive to verifying the authenticity of the replaceable module.

A method, the method comprising:

• receiving an authentication response;
• conditioning a first signal carrying the authentication response thereby generating a conditioned signal carrying the authentication response that is detectable by an authentication unit;
• performing a verification process using the authentication response carried by the conditioned signal;
• in response to performing the verification process:
• operably coupling a replaceable module to a user device in response to verifying the authentication response, the replaceable module and the user device, when operably coupled, forming a system that performs a process for depleting an item;
• or
• refraining from operably coupling the replaceable module to the user device in response to failing to verify the authentication response,
• wherein the replaceable module comprising:
• an element electrically coupled between a first line and a second line, the element forming a first current path between the first line and the second line;
• and
• a one-wire authentication element electrically in parallel with the element between the first line and the second line, the one-wire authentication element forming a second current path between the first line and the second line, the one-wire authentication element to provide an authentication response,
• wherein the replaceable module to divide a first current into a second current along the first current path and a third current along the second current path and wherein the one-wire authentication element to modulate the first current utilizing the third current.
