Abstract
Abstract A totalizer system having a first electronic device coupled to the vending machine for storing the number of vends (data) made by the vending machine, and a second device for interrogating the first device and providing a readout of said vends, e.g., in code, actual money value, or actual number of vends, or any form desired. The present system preferably includes an optical interrogation scheme using modulated light for transmitting stored vends in the first device to the second device thus eliminating human error, and an electronic memory in the first device that will store vends for a prolonged period of time even if the vending machine is unplugged.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
182 words
A totalizer transmitter for being fixedly coupled to a money operated machine for making sales, said transmitter providing a light output signal while coupled to the machine, said transmitter comprising counter means for counting data representing the number of times the machine makes a sale, a free running clock means for providing a plurality of clock signals, serial transmission means coupled to said counter, the data in said serial transmission means continuously updated from said counter in response to one of said plurality clock signals, said serial transmission means continuously providing a transmitted signal in response to another of said plurality of clock signals, said transmitted signal having an output waveform of data and clock information in a coded form in which each bit of the clock information is in the period of the output waveform and the data is the pulse width of the output waveform, and a light emitting diode coupled to said serial transmission means for transmitting light signals representing the coded output signal, whereby the transmitted signal is read out without the necessity of any external interrogation signal.
Claim 2
Dependent Claim
182 words
A totalizer transmitter for being fixedly coupled to a money operated machine for making sales, said transmitter providing a light output signal while coupled to the machine, said transmitter comprising counter means for counting data representing the number of times the machine makes a sale, a free running clock means for providing a plurality of clock signals, serial transmission means coupled to said counter, the data in said serial transmission means continuously updated from said counter in response to one of said plurality clock signals, said serial transmission means continuously providing a transmitted signal in response to another of said plurality of clock signals, said transmitted signal having an output waveform of data and clock information in a coded form in which each bit of the clock information is in the period of the output waveform and the data is the pulse width of the output waveform, and a light emitting diode coupled to said serial transmission means for transmitting light signals representing the coded output signal, whereby the transmitted signal is read out without the necessity of any external interrogation signal.
Claim 3
Dependent Claim
12 words
The transmitter of claim 1 in which said counter means is non-resettable.
Claim 4
Dependent Claim
30 words
The transmitter of claim 1 including means for providing an identifier code along with the data for transmission as part of the signal, said identifier code identifying the particular transmitter.
Claim 5
Dependent Claim
17 words
The transmitter of claim 1 in which said free running clock is disabled upon loss of power.
Claim 6
Independent Claim
239 words
A system comprising a totalizer transmitter for being fixedly coupled to a money operated machine for making sales, said transmitter providing a light output signal while coupled to the machine, said transmitter comprising counter means for counting data representing the number of times the machine makes a sale, a free running clock means for providing a plurality of clock signals, identifier generating means, serial transmission means coupled to said counter and said identifier generating means, the data in said serial transmission means continuously updated from said counter and said identifier means in response to one of said plurality of clock signals, said serial transmission means continuously providing a transmitted signal in response to another of said plurality of clock signals, said transmitted signal having an output waveform of data and identifier code and clock information in a coded form in which each bit of the clock information is in the period of the output waveform and the data and identifier code is the pulse width of the output waveform, a light emitting diode coupled to said serial transmission means for continuously transmitting light signals representing the coded output signal, whereby the transmitted signal is read out without the necessity of any external interrogation signal, and interrogating means for positioning adjacent to said light emitting diode for converting the output waveform to information representing the amount of sales detected by the totalizer transmitter and the identification of the totalizer transmitter.
Claim 7
Independent Claim
239 words
A system comprising a totalizer transmitter for being fixedly coupled to a money operated machine for making sales, said transmitter providing a light output signal while coupled to the machine, said transmitter comprising counter means for counting data representing the number of times the machine makes a sale, a free running clock means for providing a plurality of clock signals, identifier generating means, serial transmission means coupled to said counter and said identifier generating means, the data in said serial transmission means continuously updated from said counter and said identifier means in response to one of said plurality of clock signals, said serial transmission means continuously providing a transmitted signal in response to another of said plurality of clock signals, said transmitted signal having an output waveform of data and identifier code and clock information in a coded form in which each bit of the clock information is in the period of the output waveform and the data and identifier code is the pulse width of the output waveform, a light emitting diode coupled to said serial transmission means for continuously transmitting light signals representing the coded output signal, whereby the transmitted signal is read out without the necessity of any external interrogation signal, and interrogating means for positioning adjacent to said light emitting diode for converting the output waveform to information representing the amount of sales detected by the totalizer transmitter and the identification of the totalizer transmitter.
Claim 8
Dependent Claim
12 words
