Abstract

An electrochemical metal alloy identification device employing electrolytes to measure and identify different potentials of alloys is presented. This includes physical structure, disposables, electrical systems, control circuitry, and algorithms to identify alloys.

Claims (22)

1. An alloy identification device comprising:

a housing;

a carrier configured with multiple compartments configured to be received within the housing, the housing and carrier further including locking and unlocking mechanisms to lock the housing and carrier together and to allow the housing and carrier to be unlocked, wherein in the unlocked state the carrier is removable from the housing; and

multiple cartridges, each cartridge configured to be removably inserted within one of the multiple compartments of the carrier, wherein the cartridges are configured to be interchangeable between each of the compartments of the carrier, wherein the carrier is designed to hold at least some of the interchangeable multiple cartridges at a same time, and

wherein the housing configured to receive the carrier extends substantially a full length of each of the multiple cartridges, out to dispensing tip ends of the multiple cartridges.

2. The device of claim 1 wherein each of the multiple cartridges includes a reservoir designed to hold a fluid.

3. The device of claim 2 wherein the fluid in each of the multiple cartridges is an electrolyte.

4. The device of claim 3 wherein each of the multiple cartridges includes an electrolyte which is distinct from an electrolyte in other ones of the multiple cartridges.

5. The device of claim 3 wherein at least one of the electrolytes associated with the multiple cartridges is a customized electrolyte.

6. The device of claim 1 wherein each of the multiple cartridges include:

(i) a body portion having an interior area, a first end opening, a second end opening, and a slot portion within an outer surface of the body portion,

(ii) a reservoir formed in a configuration to fit within the interior area of the body portion through the second end opening of the body portion, wherein the reservoir is formed of a material having absorptive characteristics including a capability of absorbing a fluid,

(iii) an electrode component sized and inserted in operational contact with the first end opening, the electrode component having an upper portion with an open area therein and an arm portion extending from the upper portion into the slot portion within an outer surface of the body portion;

(iv) and wherein the dispensing tip end of each of the multiple cartridges includes a porous material inserted into the open area of the upper portion of the electrode component and into the interior of the body portion, wherein at least a portion of the dispensing tip end is in operational contact with the reservoir, and

(v) a cartridge cap inserted into contact with the second end opening of the body portion.

7. The device according to claim 1 further including an electrical system configured to provide electrical connection between the housing, the carrier and the cartridges.

8. The device of claim 7 wherein the electrical system includes multiple distinct electrical circuits each associated with one of multiple distinct electrolytes, wherein each distinct electrical circuit generates distinct output signals.

9. The device of claim 8 wherein the housing includes intelligent computing components configured to receive the distinct output signals and to generate an output to identify an alloy being tested, wherein the intelligent computing components store algorithms which are used to generate at least one of classification algorithms and look-up tables for the alloy identification.

10. The device according to claim 9 wherein the electrical system includes arm portions of electrodes in a movable operational contact with a portion of electrical connection lines extending through the carrier.

11. The device according to claim 1 wherein a stationary ground extends from the carrier to define a distance between a surface of an alloy being tested and the device.

12. The device according to claim 1 wherein the device is a handheld device.

13. The device of claim 1 wherein the locking and unlocking mechanisms of the housing and carrier are configured for tool-less operation.
