Abstract: A unidirectional roller chain sprocket (112, 114) for use primarily in automotive engine chain drive applications which incorporates an asymmetrical tooth (132, 136) for improved noise reduction. The asymmetrical tooth profile incorporates a flank flat (144) which is tangent to an engaging flank radius (Rf) and a first root radius (Ri). The asymmetrical tooth profile also incorporates one or more inclined root surfaces (146) which provide tooth space clearance for maintaining the chain rollers (118, 128, 130) in hard contact with the root surface (146) in the sprocket wrap (158). The asymmetrical tooth profile further incorporates pitch mismatch wherein the sprocket chordal pitch (Ps) is less than the chain chordal pitch (Ps) to facilitate a "staged"  roller-tooth contact as a roller moves into full mesh from an initial tangential impact at the flank flat (144).

Title: System and method for measuring channel quality information in a communication system
Inventor: NANDA SANJIV
IPC: H04L1/12
Filed: 1999-02-26
Granted: 2003-12-09
Abstract: A system and method to measure channel quality in terms of signal to interference plus noise ratio for the transmission of coded signals over fading channels in a communication system. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure for coherent and non-coherent transmission schemes. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes speeds. The filtered metric is mapped to the signal to interference plus noise ratio per symbol using a threshold based scheme. Use of this implicit signal to interference plus noise ratio estimate is used for the mobile assisted handoff in a cellular system, power control and data rate adaptation in the transmitter.

Title: Centrifugal separator with injection of fluidizing liquid between non-fluidized recesses
Inventor: KNELSON BENJAMIN V
IPC: B04B1/00
Filed: 1997-11-27
Granted: 2000-02-08
Abstract: A centrifuge concentrator bowl includes a plurality of fluidized recesses at axially spaced positions along the peripheral wall and between each fluidized recess and the next is provided a shallower recess which is non-fluidized which provides some collection of materials. The bowl is of a frusto-conical shape so that the open mouth is larger than the base and a restricting ring is attached at the open mouth to define an inner edge of a diameter less than that of the uppermost recess and approximating that of a recess lower in the bowl. The uppermost recess is a fluidized recess and a series of the lowermost recesses are non-fluidized. In one embodiment, the bowl includes a first frusto-conical wall portion with no recesses, a second portion with a series of non-fluidized recesses with a fluidized land portion between each and the next, and a third portion having two fluidized recesses with inserts to provide a reduced volume. The bowl acts to reduce water requirement and to improve the richness of the concentrate by reducing the volume of start-up material retained with the heavier materials collected.

Abstract: An apparatus and method for performing vertebroplasty are provided. In one embodiment of the invention, there is provided a kit for performing vertebroplasty having two packs, each pack having the necessary components for performing vertebroplasty via each pedicle of the damaged vertebrae. Each pack is sterilized, so that if the vertebroplasty performed via one pedicle is sufficient, then the second pack can be saved for later use. In another embodiment, each pack within the kit has two cements, each cement having different imaging properties, such that each cement will appear different when viewed with an imaging device in the lateral plane and/or will be viewable when overlapping. A presently preferred embodiment involves two packs having methylmethacrylate powder but each pack has a different amount of opacifier, either as supplied or added by the vertebroplasty professional, such that when each cement is mixed and injected, each cement is visible when exposed to X-ray lateral fluoroscopy. A method is also provided that utilizes the kit, and which allows a medical professional to monitor a second injection of cement via the second pedicle and thus reduce the risk of spinal cord compression or venous filling due to unwanted flow of cement into the spinal canal.

In this way, a transgenic plant can be produced with the capability of degrading fumonisin, as well as with the capability of producing the degrading enzymes. In addition, the present invention provides methods for producing the APAO enzyme in both prokaryotic and non-plant eukaryotic systems. Methods for detoxification in grain, grain processing, silage, food crops and in animal feed and rumen microbes are also disclosed.

Title: Stabilizing the position of an active element in a magnetomechanical eas marker
Inventor: GADONNIEX DENNIS M
IPC: G08B13/14
Filed: 1999-07-02
Granted: 2009-09-08
Abstract: A magnetomechanical EAS marker (20) is formed of a housing (22, 24), a magnetostrictive active element (12) in the housing and a bias element (not separately shown) fixedly mounted on the housing. A central portion of the active element is secured to the housing to keep the active element from shifting in a longitudinal direction relativ e to the bias element and to keep ends of the active element spaced from the housing. The active element remains free to mechanically resonate in response to an EAS interrogation signal. The stable positioning of the active element prevents variations in the bias magnetic field due to shifting relative to the bias element, while keeping ends of the active element free from frictional damping due to mechanical loading from contact with the housing.
