Patent application numberDescriptionPublished
20080198499Continuous mode velocity control of voice coil motor - A method of controlling the velocity of a voice coil motor (VCM), including sensing a voltage difference between the VCM and a sense resistor and driving a velocity control loop (VCL) based on the voltage difference. There is also a control loop circuit, including a current output connected to drive a voice coil motor, the voice coil motor producing a back electromagnetic field (BEMF) voltage. The circuit also includes a sense resistor connected to the BEMF output, and a BEMF resistive network comprising a first resistor and a second resistor. The circuit also includes a velocity control loop (VCL) connected to control the voltage output according to a voltage difference between (i) a junction of the sense resistor and the current output and (ii) a junction of the first resistor and the second resistor.08-21-2008

20080202403APPARATUS FOR ALTERING THE COURSE OF TRAVELLING OF A MOVING ARTICLE AND A METHOD THEREOF - The present invention relates to an apparatus for altering the course of a moving article and a method thereof comprising of a launching aircraft or surface craft to deploy said apparatus towards a moving article. The apparatus comprises of a driving mechanism (08-28-2008
20090007832METHOD FOR CHANGING THE DIRECTION OF TRAVEL OF A WATERCRAFT AND APPARATUS THEREFORE - An apparatus for retarding and/or changing the direction of travel of a sailing vessel is disclosed. The apparatus includes a watercraft (01-08-2009
20090013916Method of Intercepting and Yawing a Sailing Vessel With External Propulsion Means - A method for intercepting and yawing an errant sailing vessel is disclosed, wherein the vessel might have been hijacked or malfunctioned and in danger of colliding with an object. The method comprises dispatching a watercraft to approach the sailing vessel and secures itself to one side of the sailing vessel's hull. Preferably, a second watercraft is secured to the other side of the vessel's hull. At least one of the watercrafts is then operated to direct propulsion thrust to yaw the vessel in a desired direction. Preferably still, the first and second watercrafts are each secured respectively to the right and left sides of the vessel's hull proximate to the stem or bow end. The first (right side) watercraft then operates a fluid propulsion which thrust is directed away from the vessel's right side while the second (left side) watercraft's propulsion is on standby. As a result, the vessel is turned rightward or clockwise. Conversely, the first watercraft may be put on standby while the second watercraft's propulsion is operated such that the thrust is directed away from the vessel's left side, thereby causing the vessel to turn leftward or anti-clockwise.01-15-2009
20090020062Method of Intercepting and Yawing a Sailing Vessel - A method for intercepting and yawing an errant sailing vessel is disclosed, wherein the vessel might have been hijacked or malfunctioned and in danger of colliding with an object. The method comprises dispatching a pair of watercraft to approach said sailing vessel, providing a tow rope to be secured at one end to first watercraft and the other end to second watercraft. The tow rope is brought to extend between the first and second watercrafts over the hull of said sailing vessel. The first watercraft is then secured to one side of said sailing vessel's hull, while second watercraft pulls the tow rope away from the direction of sailing on the other side of said vessel's hull. In an alternative embodiment, the tow rope end held by the first watercraft may be secured directly to the vessel's hull, thus freeing the first watercraft to evacuate crew from the vessel to a safer distance.01-22-2009
20100058966DIVERSION OF SAILING VESSEL BY TETHERING METHOD AND APPARATUS THEREFOR WITH HARPOON MEANS - A method for diverting a sailing vessel is disclosed. A watercraft equipped with a harpoon having a hull-piercing head and a tail attached to a cable may swiftly approach the vessel in the aft position. Upon piercing the hull, an extraction-preventing means, such as spokes unfolded from the head, latching it in the hull and preventing the harpoon's withdrawal. Via a cable attached to the tail of the harpoon the watercraft may use low-speed high-traction propulsion means such as Voith-Schneider Propulsion (VSP) to pull and divert the vessel at the stern to a desired course. The watercraft may preferably have a combination of lifting hydrofoils with propellers and VSP propellers to provide the respective low-traction high-speed and high-traction low-speed modes of operation.03-11-2010

20100060700Systems and Methods for Storing Printer Cartridges - A printer may include a printer housing, a service station in the printer housing, an automated carriage assembly, and a print cartridge storage compartment. The service station defines an area for servicing one or more print cartridges. The automated carriage assembly is configured to carry the particular print cartridge through a printing area during a printing operation of the printer, and to carry the particular print cartridge to the service station area for servicing. The print cartridge storage compartment is defined by the printer housing and configured to store a spare print cartridge, the print cartridge storage compartment being separate from the service station and inaccessible to the carriage assembly.03-11-2010
