Resettable count-up timer for beverage dispense
View Patent ↗A beverage dispensing system which includes a server, a sensing system coupled to the server for detecting a quantity of beverage retained in the server, a display coupled to the sensing system, and a count-up timer coupled to the system. The display may provide indicia as to the time and/or freshness of the beverage in the server. A method for sensing and displaying a quantity of beverage in a beverage server which can also include a freshness indicator. A resettable timer is incorporated which cannot be reset until at least the sensing system has been physically or operatively uncoupled from the server. The resetting may also require the sensing system to detect an empty server upon recoupling the sensing system with the server. Further, the resetting may also require monitoring a refill function for refill occurring within a predetermined rate parameter or time.
1. A beverage dispensing system which includes a server, a sensing system coupled to the server for detecting a quantity of beverage retained in the server, a display coupled to the sensing system, and a count-up timer coupled to the system, the count-up timer being operable to begin counting the time from the start of filling of the beverage server with beverage and operable to being reset only after uncoupling the server from the sensing system, sensing the server is empty and detecting filling of the beverage server to a predetermined quantity of beverage.
2. A method for sensing a quantity of beverage in a beverage server comprising,
providing a beverage server,
providing a timer coupled to the server,
operating the timer to begin counting the time from filling of the beverage server with a predetermined quantity of beverage, and
resetting the timer to begin counting the time from filling of the beverage server with a predetermined quantity of beverage only after,
sensing the server is empty, and
detecting filling of the beverage server with a predetermined quantity of beverage.
3. The method as set forth in claim 2 further comprising providing a freshness indicator.
4. The method as set forth in claim 2 further comprising
detecting a quantity of beverage retained in the server via a sensing system coupled to the server, and
preventing resetting until sensing the sensing system has been uncoupled from the server.
5. The method of claim 2 further comprising
detecting a quantity of beverage retained in the server via a sensing system coupled to the server, and
preventing resetting of the timer unless removal of the sensing system from the server is detected and after recoupling of the sensing system with the server the sensing system indicates a predetermined quantity of beverage is dispensed into the server.
6. The method as set forth in claim 2 further comprising resetting the timer to begin counting the time from filling of the beverage server with a predetermined quantity of beverage only after uncoupling the server from a sensing system operable to sense the level or quantity of beverage in the beverage server.
7. The method as set forth in claim 2 further comprising operating the timer to count the time to a first predetermined time and then to continue counting to a second predetermined time, stopping counting upon reaching the second predetermined time and displaying an indicia of the second predetermined time.
8. The method as set forth in claim 2 wherein the step of detecting filling comprises filling for at least a minimum time whereby filling for less than the minimum time does not satisfy the requirement of detecting filling of the beverage server with a predetermined quantity of beverage.
9. The method as set forth in claim 2 wherein the step of detecting filling comprises detecting the rate of filling and if the rate is greater than a predetermined maximum rate then the filling does not satisfy the requirement of detecting filling of the beverage server with a predetermined quantity of beverage.
10. The method as set forth in claim 7 further comprising displaying the time to a first predetermined time using a first indicia and displaying the time from the first predetermined time to the second predetermined time using a second indicia.
