Abstract: A virtual router spans a number of physical routing devices. A set of physical ports on one of the physical routing devices is logically represented as a trunk. A respective port priority value is associated with each of those ports, and a device priority value is associated with the physical routing device. If a port in the trunk is out-of-service, then the device priority value can be adjusted by the port priority value associated with the out-of-service port. A corrective action can be implemented if the device priority value fails to satisfy a condition. For example, the physical routing device may failover to another one of the physical routing devices spanned by the virtual router.

Abstract: An interleaver and scheme for interleaving in which highly correlated bits are maximally separated. The scheme involves interleaving a set of bits to be delivered to a modulation system that utilizes a quantity of N carrier frequencies. A first block of N consecutive bits is assigned to each of N bins, on a one-bit-per-one-bin basis. The aforementioned assignment proceeds in a particular sequence. A second block of N consecutive bits is assigned to each of the N bins, on a one-bit-per-one-bin basis. The second block is assigned in the same sequence the first block was assigned. The second block is consecutive to the first block.

Abstract: A disposable air freshener configured to be connected to a USB port of a computer or computer peripheral device. In one embodiment, the disposable air freshener comprises a casing fabricated from a plurality of sections that have generally the same shape. At least one of these sections is configured as scented cardboard. The disposable air freshener has a printed circuit board and a heating element electrically connected to the printed circuit board. A portion of the printed circuit board extends from the casing and is configured to be inserted into a USB port so that electrical power can be applied to the printed circuit board. The heating element generates heat when it receives electrical power from the printed circuit board. Thus, when electrical power is applied to the printed circuit board, the heating element generates heat which causes the scented cardboard to emit a pleasant scent or aroma. The casing of the air freshener can be configured to have almost any geometric shape, e.g. pine tree, hamburger, chocolate bar, etc.

The oxidized organo silane film has excellent barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organo silane film can also be used as an etch stop or an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organo silane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organo silane film is produced by reaction of methyl silane, CH3SiH3, and N2O.

Abstract: A method and apparatus for depositing a low dielectric constant film by reaction of an organosilicon compound and an oxidizing gas at a constant RF power level from about 10 W to about 200 W or a pulsed RF power level from about 20 W to about 500 W. Dissociation of the oxidizing gas can be increased prior to mixing with the organosilicon compound, preferably within a separate microwave chamber, to assist in controlling the carbon content of the deposited film. The oxidized organosilane or organosiloxane film has good barrier properties for use as a liner or cap layer adjacent other dielectric layers. The oxidized organosilane or organosiloxane film may also be used as an etch stop and an intermetal dielectric layer for fabricating dual damascene structures. The oxidized organosilane or organosiloxane films also provide excellent adhesion between different dielectric layers. A preferred oxidized organosilane film is produced by reaction of methylsilane, CH3SiH3, dimethylsilane, (CH3)2SiH2, or 1,1,3,3-tetramethyl-disiloxane, (CH3)2—SiH—O—SiH—(CH3)2, and nitrous oxide, N2O, at a constant RF power level from about 10 W to about 150 W, or a pulsed RF power level from about 20 W to about 250 W during 10% to 30% of the duty cycle.
