Publication number: 20210404539Abstract: A belt drive system includes a drive sheave and a driven sheave. A drive motor turns the drive sheave when the drive motor is activated. A drive belt is connected to the drive sheave and the driven sheave so that the driven sheave is turned when the drive motor is activated. The drive motor is mounted upon a shuttle and the shuttle is slidingly mounted on a base. A drive system moves the shuttle when the adjustment motor is activated so that a position of the drive sheave relative to the driven sheave may be adjusted so as to increase a tension in the drive belt. A controller activates the adjustment motor when slippage of the drive belt on either the drive sheave or the driven sheave is detected.Type: ApplicationFiled: June 16, 2021Publication date: December 30, 2021Inventors: Jeffrey Scoville, Michael Lanphier, Michael Lee, David Snell

Publication number: 20100070656Abstract: In association with a storage system, dividing or splitting file system I/O commands, or generating I/O subcommands, in a multi-connection environment. In one aspect, a host device is coupled to disk storage by a plurality of high speed connections, and a host application issues an I/O command which is divided or split into multiple subcommands, based on attributes of data on the target storage, a weighted path algorithm and/or target, connection or other characteristics. Another aspect comprises a method for generating a queuing policy and/or manipulating queuing policy attributes of I/O subcommands based on characteristics of the initial I/O command or target storage. I/O subcommands may be sent on specific connections to optimize available target bandwidth. In other aspects, responses to I/O subcommands are aggregated and passed to the host application as a single I/O command response.Type: ApplicationFiled: September 11, 2009Publication date: March 18, 2010Applicant: ATTO TECHNOLOGY, INC.Inventors: David A.

Publication number: 20080122456Abstract: A capacitive sensor for mounting to a body, particularly a body such as a van door (55). The sensor has a sensor plate (51) to which a first signal is applied. A first guard plate (52) is interposed between the sensor plate (51) and the body (55), and a second guard plate (53) is interposed between the first guard plate (52) and the body (55). The first and second guard plates (52, 53) each have signals applied thereto which are the same or at least similar to the first signal applied to the sensor plate (51). In this way, the second guard plate (53) acts as a rear guard to the first guard (52) and reduces its capacitance to ground. This reduces the current drawn by the first guard (52), allowing it to more accurately track the signal on the sensor and consequently better mask the sensor plate (51) from the body (55).Type: ApplicationFiled: July 28, 2004Publication date: May 29, 2008Inventors: Anthony Moon, David Snell, Cynthia Anne Snell

Publication number: 20030056033Abstract: The present invention provides an improved method of ensuring the integrity of command instructions exchanged between a host and an ATA device of an array of one or more ATA devices. The invention discloses a method of error detection for transfers of both control information and command information. The invention broadly includes the steps of: writing control information to one or more locations on the selected ATA device; reading the information stored at the corresponding locations; and comparing the control information to the information stored. Other aspects of the invention include writing command information to the ATA device; reading the information stored at the location to which the command information is written; and comparing the command information to the information stored. Other aspects of the invention terminate the command instruction if any compared information is not equal; or if the command instruction is not completed within a preset time interval.Type: ApplicationFiled: September 17, 2001Publication date: March 20, 2003Applicant: ATTO Technology, Inc.Inventors: Barry J.

Patent number: 6277196Abstract: Apparatus for applying a coating of an insulation lacquer to a moving surface of a strip comprises a rotatable roller whose surface defines a multiplicity of cells and a reservoir containing a bath of heated organic/inorganic insulating lacquer in which a part of the roller surface is immersed when rotating. Insulating lacquer enters the cells of the roller surface and excess lacquer is wiped from the roller surface. A rotatable applicator roll having a substantially plain surface free of grooves or other indentations is rotated with its surface in contact with the surface of the lacquer carrying roller whereby lacquer present in the cells of the roller is transferred to the surface of the applicator roll. The surface to be coated is moved continuously past and in contact with the roll surface to apply a uniform coating of lacquer to that surface. The strip is preferably a strip of non-oriented electrical steel.Type: GrantFiled: July 21, 1999Date of Patent: August 21, 2001Assignee: European Electrical SteelsInventors: Gwilym Leslie Woodman, David Snell, Philip Beckley
