System and method of monitoring temperature
First Claim
1. A device for monitoring temperature over a period of time, said device comprising:
- (a) a temperature sensor for taking temperature measurements, and(b) a central processing unit (CPU) in electrical connection with said temperature sensor, said CPU comprising memory, said memory consisting of volatile memory into which the temperature measurements are stored, said volatile memory storing no more than a single temperature measurement at a time,(c) wherein said device is free of memory external to said CPU.

Abstract
A temperature monitoring system includes a device for monitoring temperature over a period of time, an adaptor in communication with the temperature monitoring device (TMD) and a data programming device (DPD) in communication with the adaptor. The TMD includes a temperature sensor, a central processing unit (CPU) electrically connected to the temperature sensor, and a power source for continuously supplying power to the CPU. The CPU includes volatile memory into which measurements made by the temperature sensor are stored, the volatile memory in the CPU serving as the sole memory device in the TMD. The TMD is free of means for suspending power from the power source to the CPU. In use, each successive measurement taken by the temperature sensor overwrites the previous measurement stored into the CPU volatile memory. In this manner, the TMD stores no historical data throughout its monitoring process.

12. A method of monitoring temperature using a temperature monitoring device, said temperature monitoring device including a temperature sensor and a central processing unit (CPU), the CPU comprising memory, said memory consisting of volatile memory that stores no more than a single temperature measurement at a time, said method comprising the steps of:
-
(a) taking a first temperature measurement using said temperature sensor, (b) storing the results of said first temperature measurement into the volatile memory of said CPU, (c) taking a second temperature measurement using said temperature sensor, and (d) storing the results of said second temperature measurement into the volatile memory of said CPU, the results of said second temperature measurement overwriting the results of said first temperature measurement stored in the volatile memory of said CPU.

13. A method of monitoring temperature using a temperature monitoring device, said temperature monitoring device including a temperature sensor and a central processing unit (CPU), the CPU comprising memory, said memory consisting of volatile memory that stores no more than a single temperature measurement at a time, said method comprising the steps of:
-
(a) taking a first temperature measurement using said temperature sensor during a first time interval; (b) storing the results of said first temperature measurement into the volatile memory of said CPU during the first time interval; (c) analyzing the results of said first temperature measurement using said CPU during a second time interval; (d) taking a second temperature measurement using said temperature sensor during the second time interval; and (e) storing the results of said second temperature measurement into the volatile memory of said CPU during the second time interval, the results of said second temperature measurement overwriting the results of said first temperature measurement stored in the volatile memory of said CPU.
