Automatic detection of hair characteristics using a formulation dispensing device

A system for automatically determining at least one hair characteristic for a subject, the system comprising:

• circuitry configured to receive signals from a formulation delivery device indicative of application of one or more dispensed formulation products, wherein the signals indicate power consumed by a motor of the formulation delivery device while operating a reciprocating nozzle assembly of the formulation delivery device;
• circuitry configured to analyze the signals to automatically determine the at least one hair characteristic;
• and
• circuitry configured to store the at least one hair characteristic in a usage data store.

A system, comprising:

• a formulation delivery device;
• and
• a usage analysis system;
• wherein the formulation delivery device includes:
• a motor;
• a formulation dispensing assembly comprising a reciprocating nozzle assembly operated by the motor;
• circuitry configured to generate signals indicative of application of one or more formulation products dispensed by the formulation dispensing assembly;
• and
• circuitry configured to transmit the signals indicative of the application of the formulation products to a usage analysis system;
• and
• wherein the usage analysis system includes:
• one or more processors;
• and
• a non-transitory computer-readable medium having computer-executable instructions stored thereon that, in response to execution by the one or more processors, cause the usage analysis system to perform actions comprising:
• receiving, by the usage analysis system, the signals from the formulation delivery device indicative of the application of one or more formulation products, wherein the signals indicate power consumed by the motor of the formulation delivery device while operating the reciprocating nozzle assembly of the formulation delivery device;
• analyzing, by the usage analysis system, the signals to automatically determine the at least one hair characteristic;
• and
• storing, by the usage analysis system, the at least one hair characteristic in a usage data store.
