Room temperature nanowire IR, visible and UV photodetectors
Patent No. 8,946,678
Room temperature IR and UV photodetectors are provided by electrochemical self-assembly of nanowires. The detectivity of such IR detectors is up to ten times better than the state of the art. Broad peaks are observed in the room temperature absorption spectra of 10-nm diameter nanowires of CdSe and ZnS at photon energies close to the bandgap energy, indicating that the detectors are frequency selective and preferably detect light of specific frequencies. Provided is a photodetector comprising: an aluminum substrate; a layer of insulator disposed on the aluminum substrate and comprising an array of columnar pores; a plurality of semiconductor nanowires disposed within the pores and standing vertically relative to the aluminum substrate; a layer of nickel disposed in operable communication with one or more of the semiconductor nanowires; and wire leads in operable communication with the aluminum substrate and the layer of nickel for connection with an electrical circuit.

Synthesis and incorporation of high-temperature ammonia-release agents in lit-end cigarettes
Patent No. 8,950,409
A tobacco smoking mixture and/or a cigarette wrapper with high-temperature ammonia-release agents therein are provided, wherein the high-temperature ammonia-release agents are present in an amount effective to reduce the cytotoxicity of gas phase or particulate matter formed during smoking of the cigarette. The high-temperature ammonia-release agents are capable of reducing the cytotoxicity of gas phase or particulate matter by evolving ammonia at temperatures greater than about C., wherein the ammonia can interact with the particulate matter. Additionally, the high-temperature ammonia-release agents can be formed by heating an aqueous mixture of an iron precursor compound, an ammonia source compound and an acid.

System asset repository management
Patent No. 8,955,036
A plurality of system entities described in an asset repository are identified, the asset repository defining a particular hierarchical organization of the plurality of system entities within a computing environment. A particular system entity in the plurality of system entities is tagged with a particular tag. The particular system entity is associated with a particular security policy based on the particular system entity being tagged with the particular tag. The particular security policy is applied to system entities in the asset repository tagged with one or more tags in a particular set of tags including the particular tag.

Network address repository management
Patent No. 8,954,573
A first Internet protocol version 6 (IPv6) address of a particular computing device within a network is identified using a first passive discovery sensor performing a first discovery task. A second discovery task is caused to be performed using the first IPv6 address and an attribute of the particular computing device is identified from results of the second discovery task. The first IPv6 address and attribute of the particular device is added to a repository maintaining a record of detected IPv6 addresses within the network. In some instances, a first passive discovery sensor can be one of an event-based discovery sensor, a latent-type discovery sensor, and an indirect-type discovery sensor.

Magnetic random access memory device
Patent No. 8,953,366
The present invention proposes an electronic memory device comprising a memory line including a memory domain. The memory line may contain a number of memory domains and a number of fixed domains, wherein each memory domain stores a single binary bit value. A multiferroic element may be disposed proximate to each memory domain allowing the magnetization of the memory domain to be changed using a spin torque current, and ensuring the stability of the magnetization of the domain when it is not being written. The domain boundary between the memory domain and one of its adjacent fixed domains may thereby be moved. An antiferromagnetic element may be disposed proximate to each fixed domain to ensure the stability of the magnetization of these. The value of each memory domain may be read by applying a voltage to a magnetic tunnel junction comprising the memory domain and measuring the current flowing through it.

Systems and methods for percutaneous intravascular access and guidewire placement
Patent No. 8,951,276
A device for allowing passage of a guidewire from a primary blood vessel to an adjacent secondary blood vessel includes a main body having a primary lumen and a secondary lumen, and a piercing member disposed in the secondary lumen, and configured to be moved distally out of the secondary lumen, and to pierce through tissue while being distally moved. A third lumen located within the piercing member is configured to allow placement of a guidewire from the primary blood vessel to the adjacent secondary blood vessel. In one embodiment, the secondary lumen is configured to allow articulation of the distal end of the piercing element. The piercing member has a sharp point on one end to facilitate cutting a small communicating aperture from the primary blood vessel to the secondary blood vessel.
