Patent number: 8646108Abstract: Disclosed is a hardware based secure multi-level security computing system system. The system comprises a chassis enclosing multiple separate, secure computer devices or domains, each within an electromagnetic shielding Faraday cage. The chassis structure includes internal electromagnetic shields and other features to prevent cross domain electromagnetic interference or compromising emanations. The chassis may be the size of a standard computer tower. The computer devices or domains may be configured for handling information of different classification levels. Optionally, each of the computer devices may operate on significantly less power than a standard computer. Preferably, each computer operates on no more than 50 Watts of power, more preferably on less than 35 Watts of power.Type: GrantFiled: August 3, 2012Date of Patent: February 4, 2014Assignee: Secutor Systems, LLCInventors: Peter P. Shiakallis, Ed Harvey, John McGinn, Jr., Guy Purser

Patent number: 8120383Abstract: A virtual zero delay unidirectional high voltage logic to low voltage CMOS logic voltage level translator can be achieved using a capacitive voltage divider coupled with the standard protection diodes commonly incorporated in low side logic (e.g. Xilinx Spartan-3E FPGA's). The complete voltage level translator will work equally well on frequencies from DC up to the rated operational frequency of the driver and receiver. Load side parasitic CMOS input capacitance in this case is ironically an asset rather than a liability since it can be used effectively as one element of the capacitive voltage divider. High voltage logic (e.g. 0 to 5V) can thus interface to lower voltage CMOS logic (e.g. 2.5V or 3.3V) with a minimum of additional external components and with virtually zero time delay.Type: GrantFiled: November 7, 2007Date of Patent: February 21, 2012Assignee: Avaya Inc.Inventor: John McGinn

Publication number: 20070100842Abstract: An electronic catalog is provided that stores items and attributes associated with the items. One or more of the attributes may have more than one value. Items are stored in an item table with different attributes for items stored in different rows in an attribute table. Additional items may be added to a catalog by adding additional rows to the item table, with attributes related to the additional items added as rows into the attribute table. Particular attributes may have multiple values, and attributes with multiple values are associated with sub-items that correspond to different attribute trees or attribute sets associated with the item. Searching can be performed for attribute values and search results returned indicating all items and sub-items that satisfy the search criteria.Type: ApplicationFiled: November 2, 2005Publication date: May 3, 2007Applicant: Click Commerce, Inc.Inventors: Nathan Wykes, Kevin Brackney, John McGinn, Brian Doyle, Jeff Wang, James Brown, James Harman

Publication number: 20060171785Abstract: Sediment collection devices (SCDs) which can be used to collect sediment from sediment-bearing liquid, for example runoff from construction sites, and which have improved durability, particularly when wheeled vehicles pass over them. The SCDs include a horizontal location member; and a generally vertical member comprising (1) a filter which has relatively small apertures therethrough, and (2) threshold and outflow members each of which have relatively large apertures therethrough and which together provide a sediment control chamber (SCC) between them. The height of the SCC is at least 1.5 times its width; and/or the SCC is shaped so that a vehicle wheel approaching the SCD contacts the SCD at a defined height and angle; and/or one or both of the threshold member and the outflow member has a bending or stiffening line such that different parts of the SCD respond differently to bending forces. Precursors and methods for making such SCDs are described.Type: ApplicationFiled: January 17, 2006Publication date: August 3, 2006Inventors: John McGinn, Vincent Morris

Publication number: 20060039761Abstract: A sediment control roll includes a threshold member having large apertures therethrough, a hollow sediment collection chamber, and an outflow filter having small apertures therethrough. The sediment control roll can be used to collect sediment in runoff from a construction site, or to reduce removal of sediment from an existing land mass. The sediment control roll can for example be made by rolling up extruded polymeric netting with filter cloth attached thereto.Type: ApplicationFiled: October 25, 2005Publication date: February 23, 2006Inventor: John McGinn

Publication number: 20060002773Abstract: A drain inlet cover for a drain in a road which is bordered by a sidewalk and separated from the sidewalk by a curb, with access to the drain through an opening in the curb. The cover includes a horizontal section which lies on the road and a vertical section which covers the opening in the curb. Each section includes a filter member which lies between two apertured polymeric members.Type: ApplicationFiled: May 11, 2005Publication date: January 5, 2006Inventor: John McGinn

Publication number: 20050154775Abstract: A method, apparatus, system, and signal-bearing medium that in an embodiment determine a server and a preferred delivery technique for a recipient based on information encoded in a page. In various embodiments, an identification of the server may be encoded in the page. The recipient is selected via the page, and a message is sent to the recipient via the server and the preferred delivery technique.Type: ApplicationFiled: January 8, 2004Publication date: July 14, 2005Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: John McGinn, Thomas Murphy, Paul Rieth, Jeffrey Stevens

Publication number: 20040035772Abstract: The present invention is a basket that is sealingly insertable in a grated drain. The basket is formed from inexpensive but surprisingly tough and effective polymer grating to which is bonded polymer sheet at the upper basket edges. The polymer sheet is wide enough so that it the grate of the grated drain can be picked up and put back into its concrete inset, capturing the polymer sheet edges under its heavy weight. The captured polymer sheet forms a peripheral seal between the pavement surface and the drain so that substantially all the water must pass through the basket.Type: ApplicationFiled: August 20, 2002Publication date: February 26, 2004Inventor: John McGinn

Patent number: 6595752Abstract: An improved impeller for a centrifugal pump is disclosed. The impeller is particularly suited for use in pumps in which a high head is required and in which only low shear forces must be applied to the fluid moving through the pump. The impeller comprises vanes which sweep an arc around an impeller axis to provide a smooth path past the impeller and through the pump. The vanes of the impeller are formed to cause the fluid moving over the vanes to apply a hydrodynamic force to the vane that opposes the force applied to the vane by fluid as the vane urges fluid through the pump. An impeller according to this invention does not require the supporting structures that are required by known impellers.Type: GrantFiled: July 9, 2001Date of Patent: July 22, 2003Inventors: John McGinn, Leroy S. Finnigan

Patent number: 6497532Abstract: The present invention is a general structural member assembly. A basic structural unit of the present invention has two adjacent shafts, both further having a cross sectionally triangular shape with a longitudinal side completely or substantially mostly removed to form legs. The leg ends are formed or machined such that they present two outward surfaces generally parallel to the open face of a first adjacent shaft. The outward surfaces of the leg ends are then positionally fixed, albeit with some flexible movement in some embodiments, to generally have a parallel and longitudinal interface with the longitudinal outside edges of a solid side of a second shaft. A stacked assembly may be formed from the structural members capable of sediment retention or accumulation.Type: GrantFiled: December 9, 1999Date of Patent: December 24, 2002Inventor: John McGinn
