  • Publication number: 20200078015
    Abstract: Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site. The detections may then be used to aide in the placement of the end effector and to confirm which objects to operate on, or alternatively, to avoid. Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

  • Patent number: 8655861
    Abstract: In one example, a method comprises receiving, with a data access service, an input query from an enterprise software application, wherein the data access service is positioned between the enterprise software application and a multidimensional data source; parsing the input query into a parse tree; generating an abstract syntax tree based on the parse tree, the abstract syntax tree comprising input query elements and multidimensional expression query elements based on the input query; performing an evaluation of metadata comprised in the multidimensional expression query elements of the abstract syntax tree; restructuring the abstract syntax tree based on the evaluation of the metadata; executing a query based on the restructured abstract syntax tree on the multidimensional data source; and retrieving a query result set from the multidimensional data source comprising results that are responsive to the query based on the restructured abstract syntax tree.

  • Patent number: 8635229
    Abstract: Techniques for constructing query operations associated with a report specification are described. The query operations may include a mixture of multidimensional operations and relational operations. The application of the query operations are sequenced with the computing device to reduce or eliminate certain complexities and ambiguities during generation of reports, thereby providing an improved experience for user. For example, any multidimensional rollup operation may be applied to the multidimensional representation of the data within a first timeframe and that any aggregation operation and second level filtering are applied within a second timeframe subsequent to the first timeframe. A report may be output based on a resultant data set produced by application of the query operation in accordance with the sequencing.

  • Publication number: 20130111267
    Abstract: Provided are techniques for improving a test suite. A list of tests in a test suite is created, sorted in order of increasing run time, wherein multiple tests having a same run time are sorted in order of decreasing code block coverage. For each test on the list, it is determined whether the test covers one or more code blocks not already covered by at least one previously processed test. In response to determining that the test does cover one or more code blocks not already covered by the at least one previously processed test, the test is added to an optimized test suite. The optimized test suite is stored.

  • Patent number: 6389013
    Abstract: A method of providing a back up communications link for control messages within a delivery unit. The primary means of transport for both network data and control data within the delivery unit is by means of ingress and egress buses between application modules of the delivery unit. However, control messages from a unit controller can also be delivered by means of a separate link, typically to a bus control module.
