Publication number: 20160267610Abstract: A datastore that includes property listings (e.g., for rental properties) may be accessed by a computing resource configured to execute a thumb printing algorithm to generate summary data values (e.g., thumbprint values, hash values) of digital data included one or more images of a property listing. The summary data values along with listing attributes (e.g., address, zip code, geolocation, brand, number of bedrooms/bathrooms/sleeps, amenities) of the property listing may be compared with summary data values and listing attributes of other property listings to determine if the summary data values of one or more images match and if one or more listing attributes match. A threshold number of image matches and listing attribute matches may indicate that the property listings are duplicate property listings, which may be merged, removed or replaced with links/pointers by the computer resource to increase data storage space and/or reduce data search latency times of the datastore.Type: ApplicationFiled: March 11, 2015Publication date: September 15, 2016Applicant: HomeAway, Inc.Inventors: Bill Corbett, Bryon Jacob, David Petty

Patent number: 9032248Abstract: The disclosed system and method can use memory change tracking to lessen an amount of data that is synchronized between a primary virtual machine and a failover virtual machine so that the failover virtual machine can take over operations should the primary virtual machine become unavailable. A hardware-based memory synchronization manager on a primary physical host can be used to track the changes in the memory and transmit the same to a failover physical host so that the changes can be available, if necessary, by the failover virtual machine. The change tracking can be synchronized in nearly real time between the two physical hosts and can be small enough data updates to allow minimal network bandwidth over the network.Type: GrantFiled: October 4, 2012Date of Patent: May 12, 2015Assignee: Amazon Technologies, Inc.Inventors: Heath David Petty, Daniel Christianto

Patent number: 8968660Abstract: A chemical analyzer analyzes a sample for a target chemical. The sample and reagent are added to a measurement cell until a detectable change is observed. A reference compound, which does not take part in the reaction between the target chemical and reagent, is added to the reagent. By measuring the concentration of the reference compound, the amount of reagent used may be determined. In one embodiment, a mechanism introduces the sample, adds reagent, mixes, cleans, and flushes the measurement cell, which incorporates a longitudinal chamber having inlets for the sample and reagent and an outlet for measured sample/reagent mixtures. A detector located in or adjacent to the chamber between the inlets and outlet and a piston movable in the chamber carries seals such that movement of a piston sequentially opens the inlets and expels the fluid. The analyzer also includes a device that delivers reagent to a measurement cell.Type: GrantFiled: August 17, 2011Date of Patent: March 3, 2015Assignee: Aqualysis Pty LtdInventors: Stephen Charles Davis, John David Petty, John Thomas Huberts

Publication number: 20100059423Abstract: A liquid sample is analysed for a target chemical. A sample solution is added to a measurement cell of known volume and a reagent is incrementally added to the cell until a detectable change is observed. A reference compound, of a known concentration, that does not take part in the reaction between the target chemical and reagent, is added to the reagent and by measuring the concentration of the reference compound the amount of reagent used may be determined. A single mechanism introduces a sample, adds reagent mixes cleans and flushes the measurement cell which incorporates a longitudinal chamber having a number of fluid inlets for sample and reagent and an outlet for measured sample/reagent mixtures, a detector being located in or adjacent to said chamber between the inlets and said outlet and a piston movable in said chamber carrying a series of seals such that movement of the piston sequentially opens the inlets and expels the fluid.Type: ApplicationFiled: November 23, 2007Publication date: March 11, 2010Applicant: Aqualysis Pty LtdInventors: Stephen Charles Davis, John David Petty, John Thomas Huberts

Publication number: 20070062353Abstract: A food slicing machine using a linear servo motor to reciprocate a carriage holding food products through a path that includes a slicing blade. The slicing apparatus is a modular apparatus that can be mounted to and removed from slicing machines as a unit without the need for disassembly of the components of the slicing apparatus. An adjustment mechanism for the blade guide uses two shafts that extend from a bearing plate into a finger that is mounted to the blade guide. The lower shaft has a cam nut that displaces the finger about the upper shaft to bend the blade guide. There is also an adjustment mechanism for the idler pulley of the band blade apparatus.Type: ApplicationFiled: September 21, 2005Publication date: March 22, 2007Inventors: Todd Bodey, Tony Thomas, David Petty

Publication number: 20050022870Abstract: A flow divider for use with fluent materials, such as raw sausage. The flow divider is a combination of at least two housing bodies with chambers defined by elliptical cylindrical sidewalls. Hubs with transverse vanes have necked-down regions at one end that are rotatably mounted in a similarly-sized aperture in an endwall of each housing body. The vanes' tips follow the elliptical cylindrical sidewalls in the manner of a vane pump. Sausage is conveyed from a conventional pump into the inlet of the flow divider, and flows through passages into inlet cavities, one inlet cavity per chamber, through the sub-chambers formed by the space between the vanes, and outlet cavities, one outlet cavity per chamber. The amount of sausage that flows through each chamber is equal due to the driving linkage between the hubs of each housing body.Type: ApplicationFiled: July 23, 2003Publication date: February 3, 2005Inventors: Mark Brick, David Petty
