Abstract

A cartridge engageable with a medical device, the method of making a cartridge comprising an ordered arrangement of N electrical components each with different respective values of an electrical property, and an ordered arrangement of N conductors operably coupled to the ordered arrangement of the N electrical components.
A medical device is arranged to receive a cartridge comprises for each of N conductors on the cartridge, at least a first respective contact arranged to electrically couple with the corresponding conductor when the cartridge is engaged with the medical device; the medical device also comprises an evaluation means operable to evaluate the different respective values of an electrical property of N electrical components on the cartridge, wherein the N electrical components form an ordered arrangement which is operably coupled to the N conductors on the cartridge, and a switching arrangement operable to selectively electrically couple a respective pair of contacts to said evaluation means.

First claim

1 . A method of manufacturing a cartridge engageable with a medical device, comprising the steps of:
selecting a code, responsive to the intended contents of the cartridge; selecting a value of the electrical property within a respective one of N non-overlapping sets of value ranges of an electrical property; designating a respective one of the N non-overlapping ranges to each of N conductors; associating with the cartridge an ordered arrangement of N electrical components, each of the N electrical components having a first electrical contact and a second electrical contact, the arrangement of the N electrical components operably coupled to an arrangement of the N conductors; and selecting a particular order of the N electrical components with respect to the ordered arrangement of N conductors, wherein the selected of values of electrical properties together with the selected order with respect to the N conductors of the N electrical components embodying these values signify in combination the selected code.

2 . A method of manufacturing a cartridge engageable with a medical device, the method comprising the steps of:
selecting a code, responsive to the intended contents of the cartridge; selecting a respective one of M possible values of an electrical property from each of N non-overlapping sets; associating with the cartridge an ordered arrangement of N electrical components operably coupled to an ordered arrangement of N conductors, wherein each component embodies a respective one of the selected values of the electrical property; and selecting a particular order of the N electrical components with respect to the ordered arrangement of N conductors, wherein the selected of values of electrical properties together with the selected order with respect to the N conductors of the N electrical components embodying these values signify in combination the selected code.

3 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , wherein within the ordered arrangement of N electrical components, the order of the N electrical components is arranged with respect to the ordered arrangement of N conductors to encode information.

4 . The method of manufacturing a cartridge engageable with a medical device according to claim 2 , wherein each of the N components has a first electrical contact and a second electrical contact;
the first electrical contact of each of the N electrical components share a common connection; and the second electrical contact of each respective one of the N electrical components is connected to a respective one of the N conductors.

5 . The method of manufacturing a cartridge engageable with a medical device according to claim 2 , wherein each of the N components has a first electrical contact and a second electrical contact;
the first electrical contact of each respective one of the N electrical components is connected to the second electrical contact of a respective other of the N electrical components to form N links; and each respective one of the N links is connected to a respective one of the N conductors.

6 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , wherein the electrical property is impedance.

7 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , wherein all of the N electrical components are one selected from the list consisting of:
i. resistors; ii. capacitors; iii. inductors; and iv. diodes.

8 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , wherein the cartridge further comprises a conductor separate to the ordered arrangement of N conductors and not electrically coupled to the ordered arrangement of N electrical components on the cartridge.

9 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , wherein the conductors and the ordered arrangement of N electrical components are mounted on an outer surface of the cartridge.

10 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 ,
wherein the conductors and the ordered arrangement of N electrical components are mounted on a label; the label is affixed to an outer surface of the cartridge; and the label extends around the cartridge and overlaps itself to cover the ordered arrangement of N electrical components.

11 . The method of manufacturing a cartridge engageable with a medical device according to claim 1 , further comprising a non-conductive protective layer applied over at least the N conductors.
