Patent number: 8600592Abstract: A submarine homing system includes an acoustic emitter configured to emit an acoustic signal comprising at least two narrow-band tones, each narrow-band tone having a respective predetermined center frequency. An acoustic receiver is configured to receive the acoustic signal from the acoustic emitter, and produce one or more receiver signals. A processor is operatively connected to the acoustic receiver. The processor is configured to process the receiver signals to calculate a direction between the acoustic receiver and the acoustic emitter.Type: GrantFiled: June 26, 2012Date of Patent: December 3, 2013Assignee: Her Majesty the Queen in Right of Canada as Represented by the Minister of National DefenceInventors: Garry J. Heard, Carmen E. Lucas, Nicos Pelavas, Derek A. Clark, Gordon R. Ebbeson, Richard A. G. Fleming, George Schattschneider

Patent number: 8072172Abstract: A redundant electromechanical actuator is provided that includes first and second electric motors, a common output shaft, first and second drive cable drums, first and second driven cable drums, a first cable, and a second cable. The first and second electric motors are each adapted to be controllably energized to supply a drive torque. The common output shaft is coupled to receive the drive torque supplied from one or both of the motors. The first and second drive cable drums are coupled to the common output shaft to receive the drive torque from one or both of the motors. The first and second driven cable drums are each configured, upon being driven, to rotate. The first cable is coupled between the first drive cable drum and the first driven cable drum, and the second cable is coupled between the second drive cable drum and the second driven cable drum.Type: GrantFiled: January 29, 2009Date of Patent: December 6, 2011Assignee: Honeywell International Inc.Inventors: Casey Hanlon, David M. Eschborn

Patent number: 7920941Abstract: A dust detection method and apparatus of a cleaning robot. The dust detection method involves acquiring a floor image as a current floor image of a predetermined place at a current location of the cleaning robot in the predetermined place; obtaining a difference image between the current floor image and a background image selected from a feature map consisting of a plurality of floor images of the predetermined place; and detecting a dusty area based on the difference image and adjusting a cleaning power of the cleaning robot.Type: GrantFiled: January 6, 2005Date of Patent: April 5, 2011Assignee: Samsung Electronics Co., LtdInventors: Jun-ho Park, Dong-ryeol Park

Patent number: 4933617Abstract: In a servo steering system for motor boats comprising a steering wheel which mechanically acts on the position of a hydraulic control valve, and a rubber cylinder connected to a hydraulic power unit by way of the control valve, the control valve comprises an additional adjustment unit which is connected to an autopilot unit and is controllable by this latter. In this way both normal servo-assisted hand-steering and autopilot steering are made possible in a simple manner.Type: GrantFiled: August 8, 1988Date of Patent: June 12, 1990Assignee: Hoerbiger Hydraulik GmbHInventors: Gerhard Huber, Ferdinand Gruber

Patent number: 4757243Abstract: Method and means for a regulator for the servo control of a marine craft, for instance a torpedo, with variable speed and angle of attack. A first sensor (1) monitors the angle of attack, while a second sensor (8) monitors the depth of the craft. A revolution counter (3) and a filter (4) create an acceleration-compensating signal which is subtracted from an angle-of-attack signal emitted by the first sensor (1), whereupon the signal is transmitted to a rudder servo system.Type: GrantFiled: May 1, 1986Date of Patent: July 12, 1988Assignee: Affarsverket FFVInventors: Leif Bengtsson, Nils Danielsson

Patent number: 4538230Abstract: The invention provides a vertical velocity signal and an integration signal, respectively, of two detected ambient conditions. The signals are summed, in a selectable ratio, and compared with a predetermined altitude set point. When there is a difference between the summed outputs and the altitude set point, an altitude control signal is provided to control a vertical propulsion system of an object whose altitude is to be maintained above a terrain.Type: GrantFiled: October 29, 1982Date of Patent: August 27, 1985Assignee: Conoco Inc.Inventors: Dennis K. Reust, John S. Gergely

Patent number: 3995205Abstract: A maneuvering control system particularly for use in controlling a vehicle such as a submarine or surface craft, which utilizes both manual and automatic control. Electrical signals in accordance with the manipulation of a manual control device are generated by means of a synchro transmitter and fed to a synchro differential transmitter. Automatic control signals generated in an automatic control signal generator are converted to a mechanical form by a synchro follower which provides a mechanical input to the differential transmitter. Adjustable limit stops are provided for the synchro follower output shaft to limit the automatic signal input to the differential transmitter, thereby preventing an "out-of-control" condition in the event of a malfunction in the automatic control signal generator. The output of the differential transmitter which represents the algebraic sum of the manual and automatic inputs is used to drive a synchro control transformer, which in turn drives a servo amplifier.Type: GrantFiled: April 24, 1975Date of Patent: November 30, 1976Assignee: Rockwell International CorporationInventor: George N. Klees

Patent number: 3940674Abstract: Four direct current motor systems are controlled by a single hand grip cool device. Two of the motor systems have interacting control parameters while the remaining two are controlled independently of the other motor systems. The hand operated control mechanism is moved about three mutually perpendicular control axes to control three of the motor systems and carries thereon a fourth control which is positioned so as to be actuatable by the thumb of the operator using the control. The system of the invention has particular applicability in the control of submarine vehicles.Type: GrantFiled: April 14, 1972Date of Patent: February 24, 1976Assignee: The United States of America as represented by the Secretary of the NavyInventor: George H.
