A method for data distribution, including distributing logical addresses among an initial set of devices so as provide balanced access, and transferring the data to the devices in accordance with the logical addresses. If a device is added to the initial set, forming an extended set, the logical addresses are redistributed among the extended set so as to cause some logical addresses to be transferred from the devices in the initial set to the additional device. There is substantially no transfer of the logical addresses among the initial set. If a surplus device is removed from the initial set, forming a depleted set, the logical addresses of the surplus device are redistributed among the depleted set. There is substantially no transfer of the logical addresses among the depleted set. In both cases the balanced access is maintained.

A tubing head adapter which operates to provide a supplemental sealing barrier for a tubing head while maintaining access to the interior of the tubing head. The adapter includes an annular body adapted to be secured in fixed relation to the tubing head and a dummy hanger adapted to be matedly inserted into the annular body. The dummy hanger includes an annular sleeve insert and a removable axial plug disposed within the annular sleeve insert. A plurality of extendable and retractable locking pins secure the dummy hanger in place.

Systems and methods are presented to allow or prohibit any or all services between a network and a node in the network based upon the geographic location and rate of travel of the node. One exemplary application is for the prevention of texting while driving. For example, in FIG. 1: Typical Wireless Communications Network, the location and rate of travel of the mobile station, (MS), 140, can be determined from the use of Global Positioning System, (GPS), information received by the MS, (140), and transmitted to the network. The MS, (140), may have any or all of its subscriber services enabled or disabled by the network based upon the speed that the MS, (140), is traveling and / or its geographical location. Other methods are possible to determine the location and rate of travel of a mobile station as well. In the preferred exemplary embodiment, it is possible for a mobile wireless network to determine the location and speed of an MS. The preferred exemplary embodiment will disallow the operation of features like text messaging or speaking on the mobile phone, when an individual is driving over a range of predetermined speeds. Additionally, this embodiment would disallow the operation of similar features in specific locations, like schools, and jails. In this embodiment it is also possible to allow any MS to access predetermined destinations for emergencies, like 911, at any time. This embodiment also allows services at otherwise forbidden speeds and / or locations to specific MSs or end-users. In this way public safety officials are not restricted and “hotspot” service can be offered on buses or trains. This enhancement to the network would permit more fine-grained control over where and when services can be allowed.

A method for storing data, consisting of distributing a first plurality of groups of logical addresses among one or more storage devices in a storage system, receiving a second plurality of data-sets containing the data to be stored, and assigning each data-set among the plurality of data-sets a random number chosen from a first plurality of different numbers. The method further consists of partitioning each data-set into multiple partitions, so that each partition among the multiple partitions receives a sequential partition number, assigning each partition within each data-set to be stored at a specific group of logical addresses in the storage system in accordance with the sequential partition number of the partition and the random number assigned to the data-set, and storing each partition in the storage system at the assigned specific group of logical addresses.

A swing-away hitch adapter system couples a vehicle hitch mounted device of a vehicle while maintaining the ability of the user to access the rear storage of the vehicle. The swing-away hitch adapter has a receiver insert, a base-member, a secondary-member, a hitch receiver, a hinge-pin, a swing-limiting pin, a restraining-pin, and a return limiting pin. Additional embodiments of a swing-away hitch adapter system may further include a wiring harness extension, a plug adapter, a handle attached to the secondary-member, a handle attached to the restraining-pin, and a wire attached to the restraining-pin. The swing-away hitch adapter system, in a folded condition, is ready for transportation of the vehicle. When in a swing-away condition, the swing-away hitch adapter system allows access to the rear entry of the vehicle.

A tissue puncture assembly includes an elongate tubular member having a lumen, a distal portion having a side wall, a side port opening extending through the side wall and, and a guiding surface having a distal end that extends adjacent to a distal edge of the side port opening. The tissue puncture assembly further includes a flexible puncture member insertable through the lumen of the elongate tubular member. The flexible puncture member deflects upon contacting the guiding surface to exit the elongate tubular member through the side port in a lateral direction relative to a longitudinal direction of the elongate tubular member. The tissue puncture member is capable of puncturing tissue at an oblique angle. The tissue puncture member may further adopt a pre-formed shape at its distal end to prevent inadvertent puncture of tissue and to maintain access to the puncture site. The transseptal puncture assembly may include various sensors to identify tissue structures and precisely locate the desired puncture site.

A storage system includes a RAID adapter, disk array switches, sub-processors, and hard disk drives. A disk-related operation is initiated in the RAID adapter which dispatches a command to a disk array processor (or sub-processor) in an enclosure for the processor to perform the operation on one or more drives. The adapter may dispatch the command to a processor in a single enclosure through a disk array switch or to processors in multiple enclosures through switches in upstream enclosures. The adapter is then free to perform other functions. The processor commences the specified operation on one or more selected drives. Upon completion of the operation, the results are transmitted by the processor and received by the adapter. Offloading the task to the distributed sub-processors reduces the burden on the RAID adapter, reduces system bandwidth usage, and enables access to other drives to be maintained.

A system and method are disclosed that reduce collisions on a wireless medium shared by devices associated with a wireless network, thereby improving throughput on the wireless medium. For some embodiments, a first device reserves access to the medium for a first interval, and then grants medium access to a second device for a remainder of the first interval. If the second device transmits data during the remainder of the first interval, medium access is maintained with the second device and then the second device is prevented from contending for medium access during a subsequent contention period. Otherwise, medium access is returned to the first device and the second device is allowed to contend for medium access during the contention period.
