Abstract: An implantable lead includes an inner lead subassembly contained within and movable relative to an outer lead subassembly. The inner lead subassembly has a helical electrode to pace a target anatomy. The outer lead subassembly includes a ring electrode to sense or pace the target anatomy. A threaded interface interconnects the inner lead subassembly and the outer lead subassembly such that relative rotation of the lead subassemblies causes relative axial movement between the helical electrode and the ring electrode. Other embodiments are also described and claimed.

Abstract: Examples described herein relate to migrating a virtualized execution environment from a first platform to a second platform while retaining use of namespace identifiers and permitting issuance of storage transactions by the virtualized execution environment. The first platform can include a first central processing unit or a first network interface. The second platform can include a central processing unit that is different that the first central processing unit and a network interface that is the same or different than the first network interface. The second platform can retain access permissions and target media format independent of one or more identifiers associated with the migrated virtualized execution environment at the second platform. Unperformed storage transactions can be migrated to the second platform for execution.

Abstract: A fluid injector includes a valve assembly constructed and arranged to control flow of fluid from an inlet to an outlet of the injector. A metal housing surrounds at least a portion of the valve assembly. A plastic body is molded over at least a portion of the housing. A distal end of the body defines an integral stepped portion extending from the body. A carrier surrounds at least the distal end of the body.

Abstract: A mobile communications device may include an RF signal source configured to generate RF signals over an RF frequency band(s), and an RF transmitter coupled to the RF signal source. The RF transmitter may include an RF amplifier configured to operate over a plurality of different power control levels.

The RF transmitter may further include a shunt resistor(s) coupling the output of the amplifier to a voltage reference, and the shunt resistor(s) may be configured to decrease a highest impedance change of the RF amplifier output to below a threshold impedance level. An antenna(s) may be coupled to the output of the RF amplifier to operate over the at least one RF frequency band.

Abstract: A reductant delivery unit for selective catalytic reduction (SCR) after-treatment for vehicles includes a solenoid operated fluid injector associated with an exhaust gas flow path upstream of a SCR catalytic converter. The fluid injector has a fluid inlet and a fluid outlet. The fluid inlet receiving a source of reducing agent and the fluid outlet communicating with the exhaust gas flow path so that the fluid injector controls injection of urea solution into the exhaust gas flow path. The fluid injector has an inlet tube for directing the reducing agent between the fluid inlet and the fluid outlet. A shield is fixed with respect to the fluid injector and surrounds at least portions of the fluid injector. A coil heater is integral with the fluid injector and is constructed and arranged, when energized, to inductively heat the inlet tube to thereby heat the reducing agent within the inlet tube.

Abstract: A system and method for providing redundant access paths to a storage device make use of a processor to analyze instructions received from hosts to allow for command queuing, host switching, and command replacement where necessary. The system allows for either Serially Attached SCSI or Serial ATA hard drives to be connected to the same topology and to require no host intervention on the coordination of drive access in a multi-host environment. A single ported SATA device can then appear multi-ported and can support a redundant architecture within a SAS topology.

Abstract: A multi-port switch and a method of command switching using such a switch. Multiple virtual targets provide multiple hosts with access to the physical target device attached to the target interface of the switch. The switch intelligently dispatches operations received by the virtual targets to the physical storage target device to provide shared access. In doing so, the communication between the switch and the physical target can fully comply with the SATA protocol without the physical target being aware that the operations have originated from multiple physical hosts, and without the multiple physical hosts being aware of the shared nature of the physical SATA target device.

Abstract: The present invention relates to an aqueous quick-setting bitumen-aggregate mix suitable for cold pavement of roads, parking places, sidewalks and the like. The bitumen-aggregate mix is manufactured by mixing a mineral aggregate, water, a de-emulsifier, containing hydraulic cement, and a cationic oil-in-water bitumen emulsion, containing, as an emulsifier, a salt of a tertiary diamine and a phosphoric acid. The diamine has the formula (I), where one or two of the groups R1, R2, R4 and R5 designate a hydrocarbon group of 6–22, preferably 8–20 carbon atoms, and the remaining R1, R2, R4 and R5 groups are an alkyl group with 1–4 carbon atoms, and/or a group —(A)2H, where A is an alkyleneoxy group with 2–3 carbon atoms, and s is a number from 1–4, R3 is an alkylene group with 2–4 carbon atoms and n is a number from 0–2.

Abstract: In a multi-QOS level queuing structure, packet payload pointers are stored in multiple queues and packet payloads in a common memory pool. Algorithms control the drop probability of packets entering the queuing structure. Instantaneous drop probabilities are obtained by comparing measured instantaneous queue size with calculated minimum and maximum queue sizes. Non-utilized common memory space is allocated simultaneously to all queues. Time averaged drop probabilities follow a traditional Weighted Random Early Discard mechanism. Algorithms are adapted to a multi-level QOS structure, floating point format, and hardware implementation. Packet flow from a router egress queuing structure into a single egress port tributary is controlled by an arbitration algorithm using a rate metering mechanism. The queuing structure is replicated for each egress tributary in the router system.

Abstract: Instead of alternatively utilizing only one fabric or the other fabric of a redundant pair, both fabrics simultaneously transmit duplicate information, such that each packet forwarding module (PFM) receives the output of both fabrics simultaneously. In real time, an internal optics module (IOM) analyzes each information chunk coming out of a working zero switch fabric; simultaneously examines a parallel output of a working one duplicate switch fabric; and compares on a chunk-by-chunk basis the validity of each and every chunk from both switch fabrics. The IOM does this by examining forward error correction (FEC) check symbols encapsulated into each chunk. FEC check symbols allow correcting a predetermined number of bit errors within a chunk. If the chunk cannot be corrected, then the IOM provides indication to all PFMs downstream that the chunk is defective. Under such conditions, the PFMs select a chunk from the non-defective switch fabric.
