To perform link adaptation at radio interfaces of an enhanced packet data cellular network the system behavior is simulated for different C / I conditions. Two sets of tables are obtained, each table including upgrade and downgrade thresholds expressed in terms of Block Error Rate (BLER). The tables are specialized for taking into account EGPRS type II hybrid ARQ, Incremental Redundancy (IR). Transmitted blocks are checked for FEC and results are sent to the network that continuously updates BLER. A reliability filter output is used to decide the weight between new and old measurements. IR efficiency is tested for each incoming block and an indicative variable IR_status is filtered. Each threshold of BLER to be used is obtained by linear interpolation between the tabulated threshold without IR and with perfect IR, both weighed with filtered IR_status. Filtered BLER is compared with interpolated thresholds for testing the incoming of a MCS switching condition.

Disclosed is a symmetric multiprocessor data processing system (SMP) that implements a TLBI protocol, which enables multiple TLBI operations from multiple processors within a partition to complete concurrently. Thus, a global TLB lock, synchronization, and TLB unlock is not necessary. When a TLBI instruction is executed, the master dynamically manages the behavior of the TLBI operation based on asynchronously snooping another TLBI. If concurrent TLBI management is required, then the master dynamically degrades the TLBI to a “barrier” class instruction.

A metering system is provided including a smartcard reader and peripheral computer in communication with a metering apparatus. A smartcard with memory, microprocessor, and license counter may then be engaged with a smartcard reader in the metering system to effect meter license transactions. The license transactions may be purchased by a user either to enable enhanced functional meter features via a meter upgrade process or to disable functional meter features via a meter downgrade process. Such features are typically enabled or disabled by respectively either providing or restricting access to selected portions of the meter firmware. Since both upgrades and downgrades can be effected at a utility meter, the smartcards provide transferable meter licenses. Advantages of the disclosed smartcard technology facilitate secure and reliable license transactions. Such advantages more particularly result from data encryption techniques when communicating with a smartcard and a random communication protocol implemented between smartcard and utility meter modules.

A system evaluates file metadata for files maintained in the secondary storage of a host system to determine whether one or more image files are to be downgraded. The image files selected for downgrading are reduced in size by one or more downgrading operations. The resulting file is stored in secondary storage so an image file remains in secondary storage that does not require the memory space of the previous image file. The downgrade operations may include lossless compression, lossy compression, bit depth reduction, resolution reduction, color palette, binary imaging, or a combination of a plurality of downgrade operations.

A warning document that includes the identified warning statement is generated.

Method to perform link adaptation at the radio interfaces of an enhanced packet data cellular network handling several Modulation and Coding Schemes (MCS) for maximizing data throughput. In a preliminary off-line step the system behaviour, in terms of net throughput of the various available MCSs, is simulated for different C / l conditions. From the simulation two sets of tables are obtained, each table including upgrade and downgrade thresholds expressed in terms of Block Error Rate (BLER). Thresholds correspond to switching points from an MCs to the two available MCSs having the immediate less or more protection. The two sets of tables are referred to higher or lower diversity RF environments and are further specialized for taking into account EGPRS type II hybrid ARQ, namely Incremental Redundancy (IR). During transmission the transmitted blocks are checked for FEC and the results are sent to the network. The network continuously updates BLER using exponential smoothing. In order to achieve the correct time response, in spite of that RLC blocks can be received or not, a reliability filter is provided whose output is used to decide the weight between the new and old measurements to make the BLER filter impulse response exponentially decreasing with time. The IR efficiency is tested for each incoming block and an indicative variable IR status is filtered using the same approach used for BLER. Each actual threshold of BLER to be used in link adaptation is obtained by a linear interpolation between the tabulated threshold without IR and with perfect IR, both weighed with filtered IR status. Filtered BLER is then compared with said interpolated thresholds for testing the incoming of a MCS switching condition. Power control pursues the goal of maintaining constant QoS peak throughput per time slot(Fig 16).

A navigation apparatus and a map matching method are provided which enable correct determination that a vehicle is traveling a downgrade or an upgrade link. Information on gradients of road links is incorporated and stored in a map database. An acceleration sensor detects an acceleration of the vehicle. A gradient determination section determines an angle of inclination θ of the road link being currently traveled or a value corresponding to the angle θ (sin θ) using the acceleration detected by the acceleration sensor. The gradient determination section determines a vertical distance traveled from the inclination angle and from a speed of the vehicle to accumulate the distances, each serving as a vertical deviation. If the accumulated value of the vertical deviations H is larger than a set value TH, the determination section determines that the road link being traveled is the upgrade or downgrade link. A map matching processor performs map matching processing using a result of the determination and the gradient information.

Systems and methods provide control the amount of battery SOC of a hybrid vehicle prior to reaching a downgrade section of roadway in order to offset the amount of energy that the hybrid vehicle will recuperate when traveling the downgrade. Navigation systems and methods are used to identify upcoming road conditions, such as downgrades. In this way, the battery SOC of the hybrid vehicle can maintain the capacity to allow a motor of the hybrid vehicle to assist in decelerating the hybrid vehicle during the downgrade if need be. Additionally, a situation where the battery is fully charged before reaching the end of the downgrade is avoided, which if not, could result in overcharging the battery, or having to switch to an engine-only mode of travel, where a driver must supplement engine braking with friction braking.

Implementations are provided herein for non-disruptive upgrade including rollback capabilities for a distributed file system within a cluster of nodes. To continue availability of the file system to external clients during the upgrade process, nodes can be upgraded piecemeal, for example, in one implementation, one node at a time. When a node is undergoing certain stages of the upgrade process, external clients can be directed toward the remaining nodes of the file system that are not currently being upgraded, including already upgraded nodes, to perform client activity. During the upgrade process, a first subset of nodes can be running in an upgraded state while a second subset of nodes can be in a non-upgraded state, both providing access to external clients in a seamless manner. In one implementation, a second namespace can be established at the onset of the upgrade process that reflects the new version of the operating system. The second namespace can be maintained in parallel with the original namespace during the pendency of the upgrade and / or downgrade process. A configuration translation layer can also be established on each node of the cluster of nodes. The configuration translation layer can provide the necessary key value pair translations that allow a request made an old version node to be performed by a new version node and vice versa. At the conclusion of an upgrade or a rollback, the cluster can enter a committed state and the namespace data that is no longer needed can be expired.

A system and method for reducing unrecoverable errors in a disk drive by undertaking an aggressive reassignment of slow-reading or currently recoverable-but-erroneous sectors to the spares pool is provided. A recovered error is treated by the system operating system as a fatal error and thereby the sectors involved are reassigned to the spares pool immediately. Reassignment is recommended by a reassignment utility at the disk interface level, which passes a status up to the RAID subsystem by which reassignment is performed. In order to prevent a double-disk panic, the RAID subsystem is instructed to ignore reassignment recommendations of this type (e.g. reassignment of recoverable errors) if the RAID group is currently operating in a degraded state. However, if the RAID group is undegraded, then immediate assignment of the sectors encountering the recoverable error is undertaken.

Embodiments are provided for a scheme of link adaptation (LA) in uplink grant-less random access (RA) communications. The scheme includes changing a modulation and coding (MCS) of a user, instead of using a fixed MCS over time, as the user link, channel, or non-link conditions vary during the RA communications. In an embodiment, a transmission point (TP) receives from a UE a packet encoded using aMCS, and detects a condition associated with uplink measurements or other non-link based condition of the UE. The TP then initiates an upgrade or a downgrade of the MCS in accordance with the condition, and signals the UE indicating a second MCS as a result. The UE thus sends a second packet encoded using the second MCS. In another embodiment, the UE initiates the MCS change in accordance to detecting a link or non-link based condition, such as change of mobility.
