Positional control features between replaceable units of an electrophotographic image forming device
Patent number: 9471027Abstract: A replaceable unit for an image forming device having features for aligning the replaceable unit when installed in the image forming device and to ensure alignment between the replaceable unit and a detachable unit attachable to the replaceable unit. End walls support a photoconductive drum and have a first bullet nose, second bullet nose and stop arm used for alignment of the replaceable unit in a frame of the image forming device. Support members are on a top surface of the bottom plate with a top planar surface of one of the support members forming a rotational stop and a datum surface for the detachable unit when attached. A mounting channel in one end wall provides a second datum surface for the detachable unit and a mounting channel in the other provides a deskewing plug to adjust axial alignment between the photoconductive drum and a roll in the detachable unit.Type: GrantFiled: February 3, 2016Date of Patent: October 18, 2016Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Jeffrey Alan Abler, Paul Douglas Horrall, Michael David Maul, Jennifer Marie Murphy, Joshua Carl Poterjoy -
Patent number: 9420809Abstract: Methods and systems for customized pet food are described. Generally, the systems and methods comprises obtaining a pet profile information from a user, which includes at least one of a species, an activity level, a medical history, a breed, a gender, a breeding status, a feeding method, an age, a spayed/neutered status, a snack schedule, a biological sample, a body condition, a dental health, a coat information, a digestive health information and a weight of the pet. The methods and systems may also comprise obtaining a second pet profile information from a user, related to a preference regarding an ingredient, a food form, a flavor, a protein source, a shape and a texture.

Patent number: 9411303Abstract: A replaceable unit for an electrophotographic image forming device includes a housing and a positioning stop on the housing that is translatable between a latching position and an unlatching position. The positioning stop limits the travel of the replaceable unit in the image forming device when the positioning stop is in the latching position. A compression spring that biases the positioning stop toward the latching position is positioned in line with the translation of the positioning stop between the positioning stop and a first side of a post on the housing. A deflectable arm extends from the positioning stop in line with the translation of the positioning stop proximate the compression spring. The deflectable arm includes a hook that wraps over the post in position to contact a second side of the post to limit translation of the positioning stop away from the post.Type: GrantFiled: May 29, 2015Date of Patent: August 9, 2016Assignee: Lexmark International, Inc.Inventor: Brian Lester Boettcher

Patent number: 9389576Abstract: A deskewing plug and assembly mountable in a frame having a first and a second shaft forming a nip therebetween with the second shaft rotatably mounted in a pair of opposed channels and biased toward the first shaft for adjusting the axial alignment of the shafts. The deskewing plug has a generally cylindrical body having first portion, a second portion and a tab portion. The second portion has a circumferential camming surface cooperatively engageable with the second shaft. Rotation of the plug and camming surface adjusts the axial alignment of the second shaft. The tab portion radially extends from the first portion and has radially extending ridges frictionally engageable with a wall of the opening in the frame to prevent rotation of the deskewing plug after adjustment. A cap may be provided to cover and frictionally engage the tab with the cap being fastenable to the frame.Type: GrantFiled: December 19, 2014Date of Patent: July 12, 2016Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Mark Duane Foster, Michael David Maul, Joshua Carl Poterjoy

Patent number: 9317004Abstract: A replaceable unit for an electrophotographic image forming device includes a housing having a photoconductive drum rotatably mounted thereon. The photoconductive drum has a rotational axis. A guide channel on an exterior of the housing extends parallel to the rotational axis of the photoconductive drum and is positioned to guide insertion of the housing into the image forming device. A positioning stop on the housing is movable between a latching position and an unlatching position. In the latching position the positioning stop obstructs at least a portion of the guide channel to limit the travel of the replaceable unit in the image forming device parallel to the rotational axis of the photoconductive drum. A release handle on the housing is operatively connected to the positioning stop to move the positioning stop from the latching position of the positioning stop to the unlatching position of the positioning stop.Type: GrantFiled: May 29, 2015Date of Patent: April 19, 2016Assignee: Lexmark International, Inc.Inventors: Brian Lester Boettcher, Michael David Maul, Jennifer Marie Murphy, Joshua Carl Poterjoy

Patent number: 8301057Abstract: A printer cartridge is provided that allows a charge roller to be separated from a photoconductive drum when the printer cartridge is not used within an image forming device. The printer cartridge includes the photoconductive drum, the charge roller, and a separating member having a resilient member disposed thereon with the separating member being disposed on the charge roller. The separating member engages and disengages the photoconductive drum in a first position and in a second position. The first position provides a spaced relationship between the charge roller and the photoconductive drum and the second position provides an engaged relationship between the charge roller and the photoconductive drum. The printer cartridge also includes the photoconductive drum disposed adjacent to the charge roller in an offset orientation that includes a centerline of a charge roller shaft offset by a predetermined distance from a centerline of a photoconductive drum shaft.Type: GrantFiled: January 15, 2010Date of Patent: October 30, 2012Assignee: Lexmark International, Inc.Inventors: Kevin Agnissey, Brian Lester Boettcher, Darin Michael Gettelfinger, Michael Craig Leemhuis

Patent number: 7399274Abstract: The present invention provides a capsule endoscope (CE) having sensors configured to form or to conform to the shell of the CE. The sensors are curved to correspond to the capsule's shape. According to this embodiment, the sensors may be covered by a coating material to protect the sensors. The sensors may also form the capsule shell. Instead of being covered by a shell associated with the capsule, the sensors are formed as the capsule shell. The sensors may also form part of the capsule shell. For example, one half of the capsule shell may be formed from the sensors.Type: GrantFiled: August 19, 2003Date of Patent: July 15, 2008Assignee: National Semiconductor CorporationInventors: Brian Lester Halla, Joseph Domenick Montalbo, Gobi R.
