Quality control material monitor
View Patent ↗An apparatus is disclosed designed to monitor the thermal status of a quality control material. The apparatus has the ability, with visual and/or audible means, to alert the user when the quality control material has become thermally equal to the local, ambient environment by way of natural thermal entropy. The apparatus alerts the user by visual and/or audible indicators when the quality control material, after removal from the monitor, should be returned to cool storage after a pre-determined period to maintain its designed criteria, integrity and/or purpose.
1. An apparatus to determine the thermal status of a material sample, the apparatus comprising;
a) at least one receptacle for receiving said material sample defined in said apparatus,
b) at least one sample temperature sensor in communication with said receptacle so as to be sufficient to detect material sample temperature,
c) at least one indicator,
d) at least one reference temperature sensor to detect ambient temperature,
e) a power supply to provide electrical power to operate said apparatus, and
f) at least one micro controller comprising a first program code module for causing said microcontroller to obtain a sample temperature signal from said at least one temperature sensor and to compare said temperature signal only with an ambient temperature signal from said at least one reference temperature sensor; and a second program code module for causing said at least one indicator to actuate upon said sample temperature signal equating, within a range of five percent, to said ambient temperature signal.
2. The apparatus in claim 1 further comprising an actuator and at least one material sensor in communication with said at least one receptacle so as to be sufficient to detect a presence of said material sample, and wherein said microcontroller comprises a third program code module for causing said microcontroller to obtain a signal from said at least one material sensor upon actuating said actuator, whereby a presence of a material sample in said at least one receptacle is determined.
3. The apparatus in claim 1 further comprising of a means to monitor the temperature said material sample.
4. The apparatus of claim 1 , further comprising an LCD or LED display screen, or analog display device.
5. The apparatus in claim 1 , wherein said indicator comprises a sound-producing device.
6. The apparatus in claim 1 , wherein said power supply provides electricity comprising at least one of a battery and AC power.
7. The apparatus in claim 1 , wherein said apparatus comprises a plurality of receptacles and a plurality of sample temperature sensors and said micro-controller comprises a program code module for causing said microcontroller to detect signals from said plurality of sample temperature sensors whereby a temperature of more than one material sample can be monitored and compared to ambient temperature.
8. The apparatus in claim 1 , wherein said apparatus comprises a keypad to enter programmable data about said material sample.
9. The apparatus in claim 1 , wherein said indicator is a meter.
10. The apparatus in claim 1 , wherein said indicator comprises an illuminating device.
11. The apparatus of claim 10 , wherein said illuminating device is an LED light or incandescent light.
