"CPTS" constant product temperature scanner

Abstract

The CPTS is a new device that allows the refrigerator or freezer to run about half the time of normal and maintain food freshness while saving from 50% to almost 70% on the monthly electric bill by using a laser sensor which operates at a 360 Degree and 90 Degree functionality that senses food temperature inside the box and renders a reading that sends an output signal to the compressor in the refrigeration unit and brings the temperature to its proper setting.

What is claimed is: 
     
         1 . The device has a pre-programmable ability to allow 6 or more position settings to enable the laser sensor to constantly sense temperature changes and send an output signal to the control box to start the compressor motor to cool the room to a proper food temperature from low to high with a IR non-contact visible light pointer with a 200 msc response time with an approximate range of 20 feet with a temperature range of −50 C (−58 F) to 950 C (1742 F) with a temperature resolution of 1 degree C. (1.8 degree F.). 
     
     
         2 . The device has 2 stepper motors which allow the first motor to operate at a 360 Degree functionality with the second motor operating at a 90 Degree functionality therefore allowing a full movement for the laser sensor to point in any location within the refrigeration unit. 
     
     
         3 . The device uses a separate control box mounted outside the refrigeration unit which is programmable to numerous settings:
 A. The multi-point pyrometer which is used to set the 6 or more positions the laser sensor will use to pin point food temperatures every 30 to 45 minutes.   B. The system set up which begins the programming process.   C. The Scan Programming procedure is the time standard setting.   D. The system enabled display to indicate the system is ready to begin the process.
