Filed:

Jul 11, 2012

Appl. No.:

13/546893

Inventors:

Keith Adams - San Carlos CA, US
Andrew John Paroski - San Francisco CA, US
Jason Owen Evans - Palo Alto CA, US

International Classification:

G06F 9/45

US Classification:

717140

Abstract:

Scripts are incrementally compiled at runtime to generate executable code. The incremental compilation generates executable code corresponding to a basic block of the script. The executable code for a basic block of script is generated for a set of types of variables of the basic block resulting from execution of the script in response to a request. The generated executable code is stored and executed for subsequent requests if these requests result in the same types of variables for the basic block. The incremental compilation of the script is performed in a lazy fashion, such that executable code is not generated for combinations of types of variables of the script code that are not obtained from requests received at runtime. The script may dynamically generate portions of a web page that is returned in response to a request for execution of the script.

Abstract:

An intelligent sports video and data generating system using AI detection engines in Sports Detection Devices, broadcasting commands that incorporate global time stamp information to a plurality of the Sports Detection Devices, such that the recorded sports action data can be time-aligned with video data, wherein an automatically spliced together video or data set can be generated based on the parameters of an input query.

International Classification:

G06N 5/04

A63B 24/00

Abstract:

A Sports Detection System including Sports Detection Device having an artificial intelligence (AI) recognition embedded therein and configured to run an Action Detection Model (ADM) that identifies and stores one or more individual sports actions on the Sports Detection Device for later offloading onto a secondary computing device. Methods for training and improving the ADM include tagging time-aligned portions of sensed and video data to be confirmed by profilers where the feedback can be run through a supervised learning algorithm to generate or update an ADM. The process of identifying and tagging identified portions of time-aligned data can be aided by integrating data mining and pattern recognition techniques.

Abstract:

Disclosed here are methods, systems, paradigms and structures for deleting shared resources from a cache in a multi-threaded system. The shared resources can be used by a plurality of requests belonging to multiple threads executing in the system. When requests, such as requests for executing script code, and work items, such as work items for deleting a shared resource, are created, a global sequence number is assigned to each of them. The sequence number indicates the order in which the requests and work items are created. A particular work item can be executed to delete the shared resource if there are no requests having a sequence number lesser than that of the particular work item executing in the system. However, if there is at least one request with a sequence number lesser than that of the particular work item executing, the work item is ignored until the request completes executing.

International Classification:

G06F 17/30

Abstract:

Disclosed are a method and system for implementing an array data type of a programming language using various data structures. The disclosed method includes a plurality of implementations in which the array data type may be implemented. The implementations provide an efficient way to retrieve elements from the array, especially in the order they are inserted into the array. The data structures also minimize the computing resources required to manage and access the array. The disclosed technique also selects one of the many implementations based on criteria such as access pattern or size of the array.
