Patent number: 8727516Abstract: In one example, a fluid cartridge includes a reservoir for holding a fluid, an electrical interface, an alignment feature, and a keying feature. The alignment feature is configured to, as the cartridge is inserted into a receiver, bias the electrical interface against a corresponding electrical interface on the receiver. The keying feature discriminates the cartridge from other fluid cartridges to prevent the cartridge from being inserted incorrectly into the receiver.Type: GrantFiled: July 22, 2011Date of Patent: May 20, 2014Assignee: Hewlett-Packard Development Company, L.P.Inventors: David C. Harvey, David Olsen, Ralph L. Stathem

Publication number: 20140055537Abstract: An ink cartridge for an inkjet printer includes a bottom face and a front face; an ink interface on the front face of the ink cartridge for connection to a cartridge receiving structure; a guide interface in the bottom face for guiding the cartridge along a straight line during insertion into the cartridge receiving structure for connecting the ink interface; a latch track disposed in the bottom face of the ink cartridge to guide a latch of the cartridge receiving structure; a latch stop disposed in the latch track for engaging the latch, where the latch track comprises a locking track and an unlocking track to accommodate movement of the latch with respect to the latch stop, the locking track being at least partly separate from the unlocking track; and a latch guide for redirecting the latch towards the locking track, rather than the unlocking track.Type: ApplicationFiled: October 25, 2013Publication date: February 27, 2014Applicant: HEWLETT-PACKARD DEVELOPMENT COMPANY, L.P.Inventors: David C. Harvey, Curt Gonzales, Ralph L. Stathem, David Olsen, David Welter

Patent number: 3964748Abstract: A mechanical apparatus for playing a game of chance for entertainment. By manipulation of a mallet-like device a resilient ball is caused to bounce about within a hollow open-space, then settle into any one of nine indentures in a scoring face which is marked to represent a tic-tac-toe board. A matching tic-tac-toe score card for marking results and determining the winner of the game may be included. Although designed primarily as a toy for children, it has appeal to those of all ages.Type: GrantFiled: April 28, 1975Date of Patent: June 22, 1976Inventor: David C. Harvey, Jr.
