Patent ID: 7170387

Claim:
A bus configured for use with a removable printer component, the bus comprising: a plurality of elongated, electrically-conductive first segments; a plurality of microfuses, one microfuse being provided along each of the first segments at least one of the microfuses comprising a laminate comprising a first layer and a second layer, said first layer having a lower electrical resistance than said second layer, wherein said second layer comprises: a first region adapted to be coupled to a voltage source; a second region adapted to be coupled to a ground; and a current flow region disposed between said first and second regions, wherein said current flow region is uncurved between said first and second regions and wherein said current flow region defines a recess in the plane of said second layer, said recess extending from one side of said current flow region into said current flow region, wherein said recess extends more than approximately halfway across said current flow region; an elongated, electrically-conductive second segment from which each of the first segments extends; and an elongated, electrically-conductive third segment from which the second segment extends; wherein the first segments extend from the second segment in the same direction and are substantially parallel to each other, wherein the microfuses are spaced from the second segment in a manner in which the microfuses are thermally insulated from the second segment, wherein the second segment is sized and configured to reduce the amount of heat the second segment can store, and wherein the third segment is sized and configured to reduce the amount of heat the third segment can store and is spaced from the microfuses in a manner in which the microfuses are thermally insulated from the third segment.
