AUTOMATED FLUID DISPENSING SYSTEM

摘要

A method for automated dispensing of a fluid. The method includes providing a light pulse to a location proximate a dispensing outlet from which said fluid will be dispensed, sensing a light received from that location, where the sensed light includes at least one of an ambient light or a reflection of said light pulse, generating a signal corresponding to the sensed light, generating a transistor-transistor logic (TTL) signal if the reflection of the light pulse is determined and pumping a fluid to the dispenser outlet in response to said TTL signal.

1. A method for automated dispensing of a fluid comprising:
providing a light pulse to a location proximate a dispensing outlet from which said fluid will be dispensed; sensing a light received from that location, wherein said light comprises at least one of an ambient light or a reflection of said light pulse; generating a signal corresponding to said sensed light; determining from said signal if said sensed light comprises a reflection of said light pulse or if said sensed light is ambient light; generating a transistor-transistor logic (TTL) signal if the reflection of said light pulse is determined; pumping a fluid to said dispenser outlet in response to said TTL signal; and discharging a capacitor for generating said light pulse in 5 milliseconds or less after determining that said light is ambient light.
