20140280283 | Database System with Data Organization Providing Improved Bit Parallel Processing - A database system provides vertical or horizontal pre-packing of database data elements according to a size of physical processor words in order to obtain improved parallel processing at the bit level. After processor words are populated with data from multiple data elements of the database, query operations are used which may simultaneously process the multiple data elements in each data word simultaneously in the computer arithmetic logic unit. | 09-18-2014 |
20140379691 | DATABASE QUERY PROCESSING WITH REDUCE FUNCTION CONFIGURATION - A distributed system that includes multiple database compute nodes, each operating a database. A control node provides a database interface that offers a view on a single database using parallel interaction with the multiple compute nodes. The control node helps perform a map reduce operation using some or all of the compute nodes in response to receiving a database query having an associated function that is identified as a reduce function. The control node evaluates the target data of the database query to identify one or more properties of the content of the target data. The reduce function is then configured based on these identified properties. | 12-25-2014 |
20150220583 | EXTERNAL DATA ACCESS WITH SPLIT INDEX - A split-index can be employed for access to external data. The index can be created on a primary data storage system for data stored externally on a secondary data storage system. After creation, the index can be utilized to expedite at least query execution over the externally stored data. The index can be updated upon detection of changes to data. Further, even when the index is not completely up to date, the index can be exploited for query execution. Furthermore, hybrid execution is enabled with the index and without the index. | 08-06-2015 |
20150302058 | DATABASE SYSTEM WITH HIGHLY DENORMALIZED DATABASE STRUCTURE - A database system converts a multi-table relational database into a wide table incorporating all of the information of the relational database tables and converts queries for the relational database system into a form applicable to the wide table. Dictionary compression and/or columnar store allow faster query processing despite a substantially larger size of the wide table. | 10-22-2015 |

The headgear includes a first side member positioned on a first side of the headgear, a second side member positioned on a second side of the headgear opposite the first side, a forehead strap coupled to the first and second side members and positioned on a front half of the headgear, and an occipital strap having an end coupled to one of the first side member and the second side member on the front half of the headgear and the occipital strap extending to a rear half of the headgear. | 12-17-2015 |
20150359676 | HEADGEAR FOR PROTECTIVE HEADWEAR - In one aspect, a headgear for engaging and supporting protective headwear on a wearer's head is provided. The headgear may include a first side member on a first side of the headgear, a second side member on a second side of the headgear, and a forehead strap pivotally coupled to and extending between the first and second side members. The forehead strap may be configured to engage a wearer's forehead with the headgear worn by a wearer. The headgear may also include a second strap coupled to and extending between the first and second side members. | 12-17-2015 |
20150359677 | HEADGEAR FOR PROTECTIVE HEADWEAR - In one aspect, a split forehead strap of headgear is provided. In one aspect, a headgear for engaging and supporting protective headwear on a wearer's head is provided. The headgear includes a first side member on a first side of the headgear, a second side member on a second side of the headgear, and a forehead strap coupled to and extending between the first and second side members. The forehead strap is configured to engage a wearer's forehead with the headgear worn by a wearer. The forehead strap includes an upper member and a lower member spaced-apart from the upper member along at least a portion of the lower member to provide a cavity between the upper and lower member. In one aspect, a protective headwear is provided and includes a forehead strap defining a longitudinally extending cavity that alters in thickness. | 12-17-2015 |
20150359679 | REMOVABLE SHIELD FOR PROTECTIVE HEADWEAR - In one aspect, a protective headwear is provided and includes a headgear, an outer shell rotatably coupled to the headgear, and a first shield coupled to the outer shell and rotatable between a first position and a second position. The first shield is selectively removable from the outer shell without the use of tools. The protective headwear also includes a second shield coupled to the outer shell. The first shield covers the second shield to a greater extent in the first position than in the second position. In one aspect, a method of manufacturing a protective headwear is provided. | 12-17-2015 |
20150359680 | PROTECTIVE HEADWEAR WITH AIRFLOW - In one aspect, a protective headwear is provided and includes an outer shell, a first shell duct coupled to the outer shell and including a first exhaust port, and a second shell duct coupled to the outer shell and spaced apart from the first shell duct. The second shell duct includes a second exhaust port. The protective headwear also includes a manifold positioned externally of the outer shell and configured to divert airflow into at least a first potion of airflow and a second portion of airflow. The manifold includes a first diversion member coupled to and in fluid communication with the first shell duct to provide the first portion of airflow to the first shell duct, and a second diversion member coupled to and in fluid communication with the second shell duct to provide the second portion of airflow to the second shell duct. | 12-17-2015 |
