Patent number: 6573800Abstract: In the particular embodiments of the invention described in the specification, a first signal generator produces a signal which changes in cycles having approximately straight line segments between maximum and minimum values at a first rate and a second signal generator produces a signal which changes in cycles having approximately straight line segments at a second rate which is an order of magnitude greater than the first rate. The maximum level of the second signal during any cycle is dependent upon the instantaneous signal level of the first signal and the minimum level of the second signal during any cycle is dependent upon a selected fraction of the instantaneous signal level of the first signal. The second signal is used to control the speed of a motor in a continuously changing random manner.Type: GrantFiled: June 15, 2001Date of Patent: June 3, 2003Assignee: Electric Boat CorporationInventors: Marvin E. Rosen, Vladimir Odessky, Michael J. Lubas, David Atwell

Patent number: 5879375Abstract: In one embodiment described in the specification, a surgically implantable reciprocating pump employs a check valve as the piston, which is driven by a permanent magnet linear electric motor to assist either side of the natural heart. The pump is implanted in the aorta or pulmonary artery using vascular attachment cuffs such as flexible cuffs for suturing at each end with the pump output directly in line with the artery. The pump is powered by surgically implanted rechargeable batteries. In another embodiment, pairs of pumps are provided to replace or assist the natural heart or to provide temporary blood flow throughout the body, for example, during operations to correct problems with the natural heart.Type: GrantFiled: June 7, 1995Date of Patent: March 9, 1999Assignee: Electric Boat CorporationInventors: Carl O. Larson, Jr., James S. Smith, John H. Chapman, Scot A. Slimon, John D. Trahan, Robert J. Brozek, Alberto Franco, John J. McGarvey, Marvin E. Rosen, Michael K. Pasque

Patent number: 4696244Abstract: A bag closing container device applies a strip of closure tape to a container, and sews stitches through the tape and container walls, as the container is moved past a closure station. A first sensor, located near an encoder disc driven by the container transport motor, generates a signal proportional to the container transport speed. An idler roller frictionally engaged with the closure tape carries an indicator wheel, which generates in a second sensor a signal proportional to the tape speed. The thread used in stitching the containers is wrapped around a detector wheel on its way to the closure station, and is frictionally engaged with the wheel. Wheel rotation generates in a third sensor a signal proportional to thread speed. The device includes a microprocessor which receives the signals as inputs, continually compares container transport speed and thread speed, and generates a thread fault indication if the thread and container speeds deviate from a preselected ratio.Type: GrantFiled: December 22, 1986Date of Patent: September 29, 1987Assignee: Doboy Packaging Machinery, Inc.Inventors: Mark E.
