Patent number: 7258434Abstract: The invention teaches placing labels over air diffusion vents on inkjet printheads depending upon a content of the inkjet printhead. In one embodiment, the inkjet printhead contains one or three inks in its interior and has three air diffusion vents in a lid that fluidly communicate with the interior. If the interior has one ink, a label covers the entirety of two of the three air diffusion vents to substantially prevent the two air diffusion vents from communicating with atmosphere. If the interior has three inks, a label only covers a portion of each of the three air diffusion vents and allows each to fluidly communicate with atmosphere. In this manner, single or tri-color inkjet printhead manufacturing can occur with a single lid having a multiplicity of label placement positions. The labels can have similar dimensions, dissimilar length dimensions or other.Type: GrantFiled: November 24, 2003Date of Patent: August 21, 2007Assignee: Lexmark International, Inc.Inventors: Brian D. Smith, David E. Greer, Sara M. Coneway

Patent number: 7123187Abstract: A technique uses “phase windup” to determine relative yaw of a craft from a plurality circularly polarized signals transmitted from one or more transmission sources. A first difference in carrier phase measurements taken simultaneously at time t1 is determined for first and second circularly polarized signals from a given transmitting source A second difference is then determined from simultaneous carrier phase measurements taken at time t2. A third difference, which is the difference between the first and second differences, is then used to determine the relative yaw based on a difference in wavelengths of the two signals. If more than one transmitting source is in view, a mean average of the third differences associated with the respective transmitting sources may be used to determine the relative yaw.Type: GrantFiled: December 13, 2004Date of Patent: October 17, 2006Assignee: NovAtel, Inc.Inventors: Kim Deimert, Brian D.

Patent number: 6142277Abstract: Socket-type wrenches using a magnetic ratchet/clutch-type apparatus are disclosed. The apparatus preferably employs several pawls, as well as a ratchet-type wheel for engaging the pawls. The apparatus also utilizes the wrench's body which defines a chamber in which the wheel is received for rotation relative to the wrench body. The chamber also defines pockets for positioning the pawls adjacent the wheel to facilitate their movement between a drive position and a release position. In the drive position, at least one pawl is sandwiched between the wheel and a wall of the pocket to prevent the wrench body and the wheel from rotating relative to each other which enables a drive stroke to be made with the wrench. In the release position, the pawl is disengaged from the wheel which permits one to make a return stroke with the wrench. The apparatus further includes a ring magnet mounted on at least one side of the wheel for magnetically attracting the pawls to facilitate their movement into the drive position.Type: GrantFiled: October 11, 1999Date of Patent: November 7, 2000Inventors: Franklin E.

Patent number: 4839474Abstract: A low profile switch or keypad has one or more touch buttons of circular or polygonal shape in plan formed integrally with and raised from a surrounding membrane of elastomeric material by a wall of resiliently deformable material of thickness and angle relative to the membrane so that the wall can flex under finger pressure on the or each button without deflecting the surrounding membrane. The membrane and at least the periphery of the button are relatively thick and the wall is relatively thin so that deformation during the keystroke is localized in the wall. The length of the wall is about equal to the keystroke and is relatively small compared to the width of the touch button. The junction between the wall and the membrane is located a distance greater than the keystroke above the lower surfaces of the membrane so that the wall passes overcenter during the keystroke resulting in a change in tactile sensation.Type: GrantFiled: December 10, 1987Date of Patent: June 13, 1989Assignee: Key Innovations LimitedInventors: Richard P.
