Claims29
A method for setting a date and time in a medical device to a time zone in which the medical device is located, the medical device having a microcontroller responsive to blood glucose values and connected to a wireless receiver, the method comprising:
- scanning a predetermined range of frequency values with the wireless receiver, in which at least one frequency value has a wireless signal, the wireless signal having a current date and time information encoded therein;
- determining a frequency value having a signal strength greater than as compared to any other frequency values in the predetermined range;
- setting the wireless receiver to the determined frequency value;
- and
- synchronizing a clock in the medical device to the current date and time encoded at the determined frequency value.
A method for wirelessly setting a date and time in a medical device including a microcontroller coupled to a wireless receiver, the method comprising:
- determining that a new battery has been installed into the medical device;
- automatically turning on a wireless receiver in the medical device when there is a determination that the new battery has been installed;
- receiving a wireless signal with the wireless receiver, the wireless signal comprising a current date and time information encoded therein;
- synchronizing a clock in the medical device to the wireless signal;
- and
- turning off the wireless receiver.
A method for wirelessly setting a date and time in a medical device including a microcontroller responsive to blood glucose values and connected to a wireless receiver, the method comprising:
- determining that a glucose measurement was performed with the medical device;
- automatically turning on a wireless receiver in the medical device when there is a determination that the glucose measurement was performed;
- receiving a wireless signal with the wireless receiver, the wireless signal comprising a current date and time information encoded therein;
- synchronizing a clock in the medical device to the wireless signal;
- and
- turning off the wireless receiver.
A glucose test meter comprising:
- a circuit configured to measure a glucose concentration;
- a wireless receiver configured to select a wireless signal with a signal strength greater than as compared to any other frequency values in a predetermined frequency range, the wireless signal having encoded information on a current date and time;
- a clock;
- a microprocessor configured to turn on the wireless receiver when a glucose measurement is performed with the circuit, and synchronize the clock with the current date and time information encoded by the wireless signal with the strongest signal strength;
- and
- a display configured to illustrate a current date and time therein of a time zone in which the meter is located in with a measured glucose concentration thereon, the display being connected to the microprocessor.
A glucose test meter comprising:
- a circuit configured to measure a glucose concentration;
- a wireless receiver configured to select a wireless signal with a signal strength greater than as compared to any other frequency values in a predetermined frequency range, the wireless signal having encoded information on a current date and time;
- a clock;
- a microprocessor configured to turn on the wireless receiver when a new battery is installed into the glucose test meter, control the circuit, and synchronize the clock with the current date and time information encoded in the wireless signal;
- and
- a display configured to illustrate a current date and time therein of a time zone in which the glucose meter is located in with a measured glucose concentration thereon, the display being connected to the microprocessor.
