International Classification:

B41J 2/005

US Classification:

347 59

Abstract:

A micro-miniature fluid ejecting device. The fluid ejecting device includes a semiconductor substrate having fluid ejectors formed on a surface of the substrate. A flexible circuit is fixedly attached to the semiconductor substrate. The flexible circuit has power contacts for providing power to the fluid ejectors. At least one drive circuit is connected to the fluid ejectors. The drive circuit is disposed on one of the semiconductor substrate and the flexible circuit. A fluid sequencer is connected to the drive circuit for selectively activating the fluid ejectors. The fluid sequencer is also disposed on one of the semiconductor substrate and the flexible circuit. The semiconductor substrate is attached to a housing. A fluid source is provided for supplying fluid to the semiconductor substrate for ejection by the fluid ejectors. The fluid ejecting device provides low cost construction for application specific miniature fluid jetting devices.

Appl. No.:

10/736183

Inventors:

Lucas D. Barkley - Lexington KY, US
David C. Stevenson - Lexington KY, US

Assignee:

Lexmark International, Inc. - Lexington KY

International Classification:

B41J 29/38

US Classification:

347 5, 347 9, 347 12

Abstract:

A method and device for providing a plurality of fire pulses in an ink jet printer, which includes a production of a plurality of fire signals. Each fire signal of the plurality of fire signals are asserted at a different timing than the other of the plurality of fire signals. The plurality of fire signals are combined to form a composite fire signal that maintains the different timing.

US Classification:

399 12, 399 79, 347 7

Abstract:

A method for providing a virtual replenishing of a supply item with an imaging substance includes the steps communicating to a database a first serial number associated with a first supply item; comparing the first serial number with a plurality of serial numbers stored in the database; receiving from the database one of a first data indicating non-correspondence between the first serial number with one of the plurality of serial numbers and a second data indicating correspondence between the first serial number with one of the plurality of serial numbers, wherein the second data includes a verification key; and if the verification key corresponds to the first key stored in the memory associated with the first supply item, then performing the step of allocating at least a portion of a surplus amount of the imaging substance contained in the first supply item for use.

International Classification:

G06K 15/00

US Classification:

235383, 235381, 705 14, 705 16, 705 21

Abstract:

A combined in-store and fuel center point-of-sale system having a first point-of-sale system, having a checkout manager and one or more checkout terminals, and a second point-of-sale system, having a fuel center and one or more fuel pumps, in communication with each other and with one or more primary databases containing marketing data, consumer data, customer data, master sales data, discount data, and merchandise product data, for generating a fuel discount at the second point-of-sale system based on first purchasing activity at the first point-of-sale system and/or second purchasing activity at said second point-of-sale system. The fuel discount is maintained for each customer in one of said primary databases and is based on a total purchase of products, a total purchase of product units, a total purchase amount of a product type, time period for total purchase of products, or a tiered spending amount.
