Abstract
A timer device comprising a first timer in communication with control means, the control means being in communication with an external component and the first timer sending an order to the control means after a first preset time period is counted by the first timer, the timer device also comprising a second timer in communication with the control means, the second timer counting a second preset time period that is a portion of the first preset time period. The timer device permits an accurate operation, even with changes of temperature and voltage, and with a reduced cost.
Claims5
A fragrance dispenser comprising:
- a timer device comprising a first timer in communication with a controller;
- said controller being in communication with a fragrance dispenser unit of the fragrance dispenser;
- said first timer sending an order to the controller after a first preset time period is counted by the first timer;
- the timer device further comprising a second timer in communication with said controller, said second timer counting a second preset time period, wherein the second preset time period is shorter than said first preset time period and is a portion of said first preset time period,
- wherein when said second time period is expired and said first time period is also expired, said controller is reset, and the fragrance dispenser unit starts a new operation cycle,
- wherein when the second time period is expired but the first time period is not expired, the value in a memory is incremented, and the second timer is immediately restarted to run from zero for the second preset time period;
- when said second time period is expired and said first time period is also expired, the value in the memory is read and is used to calculate a new time base, and
- wherein the new time base is used as the first time period for a next operation cycle of the fragrance dispenser unit.
A method for operating the fragrance dispenser, the method comprising:
- setting a first time period to be counted by a first timer;
- setting a second time period to be counted by a second timer, wherein said second time period is shorter than said first preset time period and is a portion of the first time period;
- when said second time period is expired, but said first time period is not expired, the second timer beginning again the measure of the second time period;
- and
- when said second time period is expired and said first time period is also expired, resetting a controller, and starting a new operation cycle of the fragrance dispenser,
- wherein when the second time period is expired but the first time period is not expired, incrementing a value in a memory, and the second timer is immediately restarted to run from zero for the second preset time period;
- when said second time period is expired and said first time period is also expired, reading the value in the memory and using the value to calculate a new time base, and
- wherein the new time base is used as the first time period for a next operation cycle of the fragrance dispenser unit.
