International Classification:

G06F 12/00

US Classification:

711154, 711100, 711108, 718100, 718102, 718103, 718104, 3703957, 37039572, 370411, 370412, 370413, 370414, 370415, 370416, 719320

Abstract:

Mechanisms for reducing the number of block masks required for programming multiple access control lists in an associative memory are disclosed. A combined ordering of masks corresponding to multiple access control lists (ACLs) is typically identified, with the multiple ACLs including n ACLs. An n-dimensional array is generated, wherein each axis of the n-dimensional array corresponds to masks in their requisite order of a different one of the multiple ACLs. The n-dimensional array progressively identifies numbers of different masks required for subset orderings of masks required for subsets of the multiple ACLs. The n-dimensional array is traversed to identify a sequence of masks corresponding to a single ordering of masks including masks required for each of the multiple ACLs.

Sing Chin - Pleasanton CA, US
Amit Agarwal - Mountain View CA, US
Patrick Morin - Fremont CA, US

International Classification:

A61B 18/18
A61B 18/04

US Classification:

606033000

Abstract:

An adjustable surgical clamp including one or more ablation elements creates a circular lesion in a first operating mode and a linear lesion in a second operating mode. A “box” lesion surrounding all four pulmonary veins may be formed by using the clamp to create two complimentary C-shaped lesions about pairs of the veins. A thermochromic liquid crystal strip that changes color at a tissue-ablating threshold temperature may be mounted on the surgical clamp to monitor temperature of the ablated tissue. Two microwave antennae may be positioned on the jaws of the clamp relative to each other to produce a combined substantially uniform field of tissue-ablating energy between the jaws.

International Classification:

A61B 17/08

US Classification:

606157

Abstract:

Devices, tools and methods for occluding fluid flow between two walls of tissue in a patient. Two walls of tissue are compressed together with sufficient compressive force to prevent fluid flow between the two walls, while ensuring that the compressive force is not so great as to cause tissue necrosis. The devices, tools and methods may be carried out using minimally invasive surgical techniques, such as in reduced-access surgical sites. Devices, tools and methods are provided for occluding an atrial appendix.

International Classification:

A61M 37/00

US Classification:

604 24

Abstract:

A surgical blower for providing a directed stream to clear a surgical site, that can be used in multiple different use modes. In one use mode, the surgical blower is handheld by a user during operation. In another mode, a distal end portion of the blower is fixed to a foot of a stabilizer instrument and the handle of the blower is handheld. In another mode, a distal end portion of the blower is fixed to a foot of a stabilizer instrument and the handle of the blower is fixed to a stationary object such as a sternal retractor. In another mode, the distal end of the blower is free and the handle of the blower is fixed to a stationary object. An apparatus including a blower and a stabilizer is provided. Methods of using the blower as well as the apparatus are also provided.

Abstract:

In general, the subject matter described in this specification can be embodied in methods systems, and program products. A request to store data is received. The data is stored as an object in a repository. A request to create a table is received, where the request identifies a name for the table. The table is created with the name. A request to import the data into the table is received. The data is imported into the table, where importing the data in the object into the table includes converting the data in the object into columnar stripes, and storing the columnar stripes in association with the table. A request to perform a query on the table is received, where the request includes the query and identifies the table. The query is performed on the table, where performing the query includes querying one or more of the columnar stripes.
