Title: Distributed processing ethernet switch with adaptive cut-through switching
Inventor: GRIDLEY CURTIS D
IPC: H04L12/56
Filed: 1995-09-11
Abstract: A packet switching system includes at least two network cards (100) each receiving data packets via a plurality of associated ports (P1-P8), a system card (200), and an interconnect (20) for connecting the system card to the network cards. Each one of the network cards comprises a plurality of port controllers (110) for sending and receiving packets to and from a corresponding port and a packet processor (130) for buffering packets received by the port controllers. The packet processor then sends destination addresses to the system card via the interconnect and receives forwarding information from the system card. The processor then forwards the packet in response to the forwarding information. The processor begins forwarding the packet in response to the forwarding information before the packet has been entirely received and checks the integrity of the packet by reference to check sum information contained in the packet as in cut-through switching. Future packets from the source port have their validity checked prior to forwarding in response to receiving an invalid packet from the source port as in store and forward switching.

Abstract: In this method for producing capacitive alumina-ceramic absolute pressure sensors sorted in high-precision zero-point long-term stability defect classes referred to a measured-value span csp, the sensors are firstly produced conventionally: a substrate is provided with an annular first electrode and, at the center, a circular second electrode insulated from the first; a diaphragm is provided with a third electrode, and the substrate and diaphragm are joined tightly together in a vacuum by the mutually facing electrodes, at an outer edge through the interposition of an active brazing ring with the formation of a chamber, with the result that a pressure-dependent capacitance Cp and a pressure-independent capacitance Cr are produced. Then, using the equation c = (Cp-Cr)/Cp = k1(p-p0)+k0, at room temperature and under a vacuum (= p --> 0 ) a first zero value cn2 = -k1p0+k0 is determined by means of a capacitance zero-point measuring device having the zero-point measuring error Fn. A second zero value cn2 = -k1p0 ' +k0 is determined f or each sensor by means of the same measuring device after the sensors have been stored in a gas during a period t in such a way that the pressure and/or temperature of the gas was raised, or its molecular weight was lowered, with respect to normal atmospheric conditions. Then the difference .delta.cn between the first and second zero values .delta.cn = cn1 - cn2 k1.delta.p0 is formed, and the value .delta.cn/csp is compared with the value Fn/csp. It is also possible to make use analogously of the zero-point temperature coefficient.

Title: Protection from viral infection via colonization of mucosal membranes with genetically modified bacteria
Inventor: LEE PETER POON-HANG
IPC: A01N63/60
Filed: 1996-03-08
Abstract: This invention relates to the use of genetically modified, non-pathogenic bacteria on the mucosal surfaces of a host to inhibit infection by specific viruses at mucosal surfaces. Specifically, non-pathogenic bacteria are modified to acquire the capacity to bind and functionally inactivate specific viruses. Further manipulations are devised to ensure the persistent colonization of said bacteria on the desired mucosal surface of a host. The capacity to bind a pathogen by said bacteria may be accomplished through the expression on the bacterial surface of a molecule, either a polypeptide or carbohydrate moiety, which binds specifically to a molecule on the target virus. Such a capacity may be conferred upon said bacteria via genetic manipulations. Genetic manipulations of said bacteria may be carried out in vitro and the genetically-engineered bacteria applied onto the desired mucosal surface of a host, or genetic material may be directly introduced into bacteria which are already resident on the desired mucosal surface of a host through a vector.

Title: Multiple data layer optical disk drive system with fixed aberration correction and optimum interlayer spacing
Inventor: ROSEN HAL JERVIS
IPC: G11B7/24
Filed: 1996-02-01
Abstract: A multiple data layer optical disk drive system has fixed aberration correction and uses a disk with maximum interlayer spacing for reduced interlayer crosstalk. In one embodiment the multiple data layer disk has a substrate with a thickness that is reduced by approximately one-half the thickness of the spacer layer that separates the first and last data layers. The disk is designed to operate with a lens that has spherical aberration correction to compensate for the thickness of a conventional single data layer disk. This allows the disk drive to handle multiple data layer disks as well as to be backward compatible and thus handle conventional single data layer disks. The thickness of the substrate material plus one-half the thickness of the spacer layer material (which may have a different index of refraction than the substrate material) is equivalent, for purposes of spherical aberration correction, to the thickness of the substrate material used in the conventional single data layer disk. The focused spot with minimum spherical aberration is thus located at the middle of the spacer layer rather than one the first data layer. The spacer layer thickness is selected so that when the focused spot is located on either the first or last data layer there is some deliberately designed spherical aberration, although an amount that is acceptable. As a result the thickness of the spacer layer can be significantly increased to thereby reduce interlayer crosstalk. In another embodiment the substrate thickness and spacer layer thickness are selected and then the lens is corrected for spherical aberration corresponding to the thickness of substrate material plus one-half the thickness of spacer layer material.

Abstract: A diagnostic method and kit for assessing the risks of smoking and CYP2A6-related cancers in an individual. Specifically, there is disclosed a diagnostic method and kit which facilitates identification of individuals who: (i) are at risk of becoming smokers, (ii) smoke more or less if they become dependent, and/or (iii) may be at relatively higher or lower risk for cancer due to both decreased smoke exposure and decreased CYP2A6-mediated activation of procarcinogens. The diagnosis involves analyzing (via a genotype or phenotype assay) a DNA-containing bodily sample from the individual for the presence of a mutant allele of human cytochrome P450 enzyme CYP2A6. If at least one mutant allele of human cytochrome P450 enzyme CYP2A6 is present in the individual, that individual: has a lower risk of becoming a smoker, smokes less if he/she becomes dependent and is at relatively lower risk for cancer due to both decreased smoke exposure and decreased enzyme-mediated activation of tobacco smoke procarcinogens. Various prophylactic (i.e., prevention and treatment) compositions and methods are also described.
