Abstract
A non-contact coding device working in a magnetic field, for use with a liquor bottle stopper and electromagnetic valve system. The stopper can be provided with a secondary coil and a diode bridge/rectifier circuit for powering a serial number identifier chip, which serially varies the impedance of the secondary coil. A primary coil on activator unit is coupled with the secondary coil to provide power and read the serial number. The activator unit can also be provided with a number of Hall effect transducers, and the stopper a number of metal peg holes, such that when the transducers are aligned on top of the holes, the presence/absence of metal pegs can be read to reproduce the serial number.
Claims10
A beverage dispenser coding device for use with a magnetically activated bottle stopper valve, the device comprising:
- a primary inductance coil provided on an activator coil unit for use in opening the stopper valve;
- a secondary inductance coil provided on the stopper valve;
- rectifier means connected to said secondary coil for rectifying and regulating current generated in said secondary coil;
- serial identifier circuit means connected to said rectifier means for making a pattern of impedance changes in said secondary coil, said pattern being a serial bit pattern representing an identification number;
- an oscillator connected to said primary coil;
- and
- demodulator and decoder means connected to said primary coil for detecting and decoding said pattern to obtain the identification number.
A beverage dispenser coding device for use with a magnetically activated bottle stopper valve, the device comprising:
- a plurality of Hall effect transducers provided on a base of an activator coil unit for use in opening the stopper valve;
- a plurality of metal peg receiving means provided on the stopper valve to be proximate said transducers when said activator coil unit is placed on the stopper valve;
- alignment means for aligning said transducers with respect to said peg receiving means in a predetermined position;
- and
- decoder means for reading said transducers when the activator coil is energized to determine whether a metal peg is present in said corresponding metal peg receiving means and thereby to obtain a binary encoded identification number.
