Publication number: 20130049938Abstract: The present invention relates generally to the field of a system and method of interaction between an end user and a sewing machine. The sewing stitch patterns are transmitted to the mobile device through a wireless signal along with a user identification number to either a server or a wireless receiver module. The server uses the user identification number to look up the user's preferred Internet vendor and content provider. Once the preferences have been determined, this information is sent from the server to a wireless receiver module. The wireless receiver module will serve as a duel function as a receiver and transmitter of signals or send a signal directly to the wireless receiver module. The wireless receiver module transmits a control signal and controls the operation of a motor unit The wireless receiver module transmits a feedback wireless progress signal.Type: ApplicationFiled: August 24, 2012Publication date: February 28, 2013Inventor: David Hooke

Patent number: 7521108Abstract: One leg of a connector connector is embedded inside a slot cut in a base panel structure. Adjacent laterally extensive legs overlap and are bonded to the face sheet of the base panel structure. Structural members can be attached to the remaining leg(s) of the connector. The legs bonded to the base panel structure enable loads to be transferred to or from the panel structure, and enable peel-off loads to be distributed through the base panel structure.Type: GrantFiled: June 4, 2003Date of Patent: April 21, 2009Assignee: Lockheed Martin CorporationInventors: Walter M. Franklin, III, David A. Hooke

Patent number: 7233837Abstract: An apparatus for performing machining operations on an object includes a carriage, a movable head configurable with an operating attachment to perform the machining operations on the object, and a position determination system operable to determine the spatial relationship of the carriage and the object and provide a first signal representative thereof. The position determination system periodically determines the spatial relationship of the head to the object during machining operations on the object and provides a second signal representative thereof. The second signal is used to re-position the head to a desired position during the machining operations.Type: GrantFiled: October 12, 2004Date of Patent: June 19, 2007Assignee: Lockheed Martin CorporationInventors: Matthew G. Swain, David A. Hooke

Publication number: 20050145149Abstract: This invention comprises a means to control stitch length of household sewing machines when used on free-motion quilting frames. A sensor in the form of a computer mouse or a pair of sensors in the form of optical encoders is used to determine the translational speed of the set of carriages that hold the sewing machine. This information is sent to electronic circuitry that converts this information to an electrical resistance which is applied to the foot pedal control electrical connector on the sewing machine. When thusly applied, this resistance sets the rotational speed of the sewing machine. This invention achieves stitch length uniformity by maintaining the proper relationship between the input signal from the sensor or sensors caused by carriage translation and the output resistance to the sewing machine which controls its rotational speed.Type: ApplicationFiled: October 26, 2003Publication date: July 7, 2005Inventor: David Hooke

Patent number: 6873880Abstract: A machine for performing machining operations on a work-piece is disclosed that includes a carriage with a robotic arm mounted thereon. The arm includes a movable head containing a tool for performing the machining operations on the work-piece. A laser position determination system is included for determining the actual spatial relationship position the carriage and the work-piece and providing a first signal representative thereof and further determining the spatial relationship of the head to the work-piece during actual machining operations on the work-piece and providing a second signal representative thereof. A computer having a computer program provides a third signal to the robotic arm for machining the work-piece based on a predetermined spatial relationship between the carriage and the work-piece and for receiving the first and second signals and adjusting the third signal based on the actual spatial relationship between the carriage and the work-piece and the head and the work-piece.Type: GrantFiled: December 26, 2001Date of Patent: March 29, 2005Assignee: Lockheed Martin CorporationInventors: David Hooke, Matt Swain

Patent number: 6536090Abstract: Improved joints for cryogenic liquid-containing tanks are disclosed. The joints include a support plate, a lower arm mounted on the support plate, an upper arm mounted on the support plate spaced from the lower arm, and tank skins extending into the space between the lower and upper arms. Sealing layers are provided between the tank skins and the joint arms. The joints are particularly useful for space launch vehicle cryogenic liquid propellant tanks which must be lightweight, withstand high structural loads and maintain leak-free conditions.Type: GrantFiled: August 28, 2000Date of Patent: March 25, 2003Assignee: Lockheed Martin CorporationInventors: Walter McRae Franklin, III, David A.

Publication number: 20010035259Abstract: Disclosed is a method and apparatus for applying large or pull-off loads to a base sandwich panel structure through a wide range of temperatures, including cryogenic temperatures. The apparatus comprises a “+” shaped connector having a vertical leg and laterally extending horizontal legs. The lower portion of the vertical leg is secured in a slot formed in the base sandwich panel structure, while the horizontal legs are secured to a major surface of the base sandwich panel structure adjacent the slot. A load application member is then secured to the upper portion of the vertical leg. The vertical leg facilitates the transfer of loads to or from the base sandwich panel member and the laterally extensive horizontal legs facilitate peel-off shear loads to be distributed through the major surface of said panel.Type: ApplicationFiled: May 21, 2001Publication date: November 1, 2001Applicant: Lockheed Martin CorporationInventors: Walter M.
