Appl. No.:

09/715837

Inventors:

Piyush Gupta - Cupertino CA, US

Assignee:

Softface, Inc. (a Subsidiary of Ariba, Inc.) - Sunnyvale CA

International Classification:

G06Q 30/00

US Classification:

705 26, 705 1, 705 27, 705 37

Abstract:

A system of performing reserve price reverse auctions is disclosed. In one embodiment, the reverse auction immediately ends if an offer below the reserve price is received. In another embodiment, the reverse auction continues until the buyer accepts an offer such that transaction with the accepted offer is consummated or a time period expires. If the time period expires and no offer is below the reserve price, then the user select from the received offers. If there is at least one offer below the reserve price and at least one other offer, then the system presents the user with the received offers and gives the user a time period to select one. If the user selects an offer, a transaction with the select offer is consummated. If no offer is selected, then a transaction with the lowest received offer is consummated.

US Classification:

700232

Abstract:

A pickup location that includes a control station and one or more storage compartment modules provides the ability for items to be ordered and delivered for pickup by a user without having to pack those items in a shipping package prior to shipping from a materials handling facility. Delivering items for pickup by a user without having to package the items prior to shipping, may provide a better experience for the customer, reduce waste in packaging material and a lower cost of delivering the ordered items to the customer.

International Classification:

G01P 2100
H01L 41107

US Classification:

73 1D

Abstract:

A rotation rate sensor which employs a built-in (i. e. internal) test circuit. The rotation rate sensor includes a piezoelectric structure. Deposited on the piezoelectric structure are at least two pickup high and two pickup low electrodes. A pickup circuit is coupled to the pickup high and pickup low electrodes. During a normal mode of operation, the piezoelectric structure is subject to a rotation about one of its axis. In response, the pickup circuit generates a rate signal which corresponds to the rotation rate of the piezoelectric structure. The test circuit is coupled to the pickup low electrodes. During a test mode of operation, the piezoelectric structure is also subject to a rotation about the axis. But, the test circuit generates at the same time a test signal which is provided to the pickup low electrodes and which corresponds to a pseudo rate of rotation. In response, the pickup circuit generates a rate signal which corresponds to the sum of the actual rate of rotation of the piezoelectric material plus the pseudo rate of rotation.

Assignee:

New S.D., Inc. - Concord CA

International Classification:

H01L 4108
G01C 1956

US Classification:

310370

Abstract:

A rotation rate sensor which uses a double ended tuning fork having a mounting base with only a single exclusive mounting surface. The mounting base is surrounded and centrally disposed within the body of the tuning fork. The mounting base is joined to the body by a suspension system which is also disposed within the body of the tuning fork. The tuning fork is mounted in the housing only at the single exclusive mounting surface.

International Classification:

H04L 43/16
G06F 16/28

Abstract:

Techniques are described herein that are capable of performing an aggregation-based determination of resiliency of a cloud computing service to chaos events. Chaos events are executed against a cloud computing service during a time frame that includes multiple time periods. For each chaos event, service health indexes (SHIs) that correspond to the time periods are calculated. Each SHI indicates an extent to which indicators, which represent respective measurements of performance of the cloud computing service during the respective time period, satisfy respective criteria. The SHIs for each chaos event are analyzed to provide a respective resiliency score. At least some of the resiliency scores of the respective chaos events are aggregated to provide an aggregated resiliency score, which represents resiliency of the cloud computing service to the chaos events.

Abstract:

Methods, systems, and computer-readable media for global column indexing in a graph database are disclosed. A plurality of data elements of a graph database are stored. The triples comprise identifiers, column names, and values. The column names are globally scoped in the graph database and are associated with data types. Indices corresponding to the column names are created. A particular one of the indices comprises one or more of the values associated with the corresponding column name. A query is performed on the graph database using one or more of the indices corresponding to one of more of the column names associated with the query.

Abstract:

Methods, systems, and computer-readable media for query language interoperability in a graph database are disclosed. Data elements are inserted into a graph database using one or more of a plurality of graph database query languages. The graph database query languages comprise a first graph database query language associated with a first data model and a second graph database query language associated with a second data model. The data elements are stored in the graph database using an internal data model that differs from the first and second data models. One or more of the data elements are retrieved from the graph database based at least in part on a query. The query is expressed using a different graph database query language than the graph database query language used to insert the one or more retrieved data elements.
