US 5,410,474 A · Buttonless memory system for an electronic measurement device

Abstract

The buttonless memory system of the present invention retrieves and stores the measurement results of a sample for the user of an electronic measurement device, particularly a portable and personal electrical measurement device, with minimal user interaction. The user simply activates the portable measurement device and waits as the buttonless memory system initially cycles through the stored measurement results. The buttonless memory system stops retrieving from memory when the measurement device detects a sample or control solution. After test measurement of the sample, the user can choose to store the measurement result by deactivating the measurement device during the time the memory display is on. If the sample is a control solution, the user can delete the measurement result from memory by waiting and deactivating the measurement device after the memory display is off. In this way, the buttonless memory system provides a simple and effective memory management scheme for measurement devices.

Dependent claims

A buttonless memory system for an electrical measurement device, said measurement device including a measurement mechanism for analyzing a sample, said measurement device further including a display for displaying a result derived from said analysis, said measurement device being characterized as a measurement device for analyzing liquid samples, comprising:

a memory for storing said result along with previous results stored in said memory;
and
a processor coupled to said measurement mechanism, said processor controlling said analysis of said sample by said measurement mechanism and calculating said result from said analysis, said processor further coupled to said display and said memory, said processor displaying said previous results and indicating during a first time period that said display is displaying said previous results stored in said memory, said processor storing said result for a second time period after calculating said result such that said result remains stored in said memory if said measurement device is turned off during said second time period, said processor deleting said result from said memory if said measurement device is not turned off during said second time period.
