Abstract: The present application is directed to a host-based IDS on an HP-UX intrusion detection system that enhances local host-level security within the network. It should be understood that the present invention is also usable on, for example, Eglinux, solaris, aix windows 2000 operating systems. It does this by automatically monitoring each configured host system within the network for possible signs of unwanted and potentially damaging intrusions. If successful, such intrusions could lead to the loss of availability of key systems or could compromise system integrity.

Abstract: A glass composition consisting essentially by mol percent of about 55<SiO2<75; 5<BaO<30; and 2 <MgO<22 for use as a matrix of composite materials. A method of making a glass matrix-ceramic particulate composition useful for sealing electrochemical structures, such as solid oxide fuel cells is also disclosed. Method steps include the admixture of finely divided Mg2SiO4 particulates with the matrix glass, to reach an overall composition by mol percent of about 55<SiO2<65; 5<BaO<15; and 25<MgO<35.

Abstract: This invention is directed to metal-matrix composites which include a substantially continuous phase of metal and reinforcing ceramic particulate substantially uniformly dispersed therein and comprising at least two of barium titanium, titanium dioxide, and titanium nitride. The composite may include other reinforcing ceramic particulate materials like metal carbides such as titanium carbide and other titanates like calcium titanate. The reinforcing particulate can comprise up to about 70 volume percent of the composite and have an average particle diameter of between about 0.1 micron and 100 microns. In forming the composite, the metal powder employed has an average particle diameter between about 1 and 20 microns. The composite is useful to manufacture, e.g., automotive parts such as brake rotors and structural components.

Abstract: Method of surface finishing covalent-ionic ceramics comprising: (a) repeatedly rubbing a finishing medium against an exposed surface of the ceramic, the medium being constituted of an ionic bonded oxide having grains harder than the grains of the covalent-ionic bonded ceramic; (b) interrupting the rubbing at frequent intervals to dress the medium by a single point diamond tool; and (c) continuing the repeated rubbing and dressing interruptions of steps (a) and (b) until a surface roughness of about 0.04 micrometer Ra has been achieved on the ceramic and the exposed surface of the ceramic retains an ionic residue of the finishing medium. Also, a method of effecting reduced friction between lubricated rubbing surfaces, comprising: (a) forming one of the rubbing surfaces of silicon nitride based ceramics having a polished surface roughness about 0.

Abstract: Method for the determination of chlamydial or gram negative bacterial antigen comprising contacting a sample potentially containing extracted antigen with an optically active surface comprising an attachment layer, and a layer of non-specific protein.

Abstract: A method for forming an optical device for detecting the presence or amount of an analyte of interest comprising a substrate which supports an optically active layer, an attachment layer provided on the optically active layer, and a receptive layer specific the analyte provided on the attachment layer. The method comprises forming the optically active layer with a chosen refractive index on the substrate by curing the optically active layer on the substrate at a controlled temperature or for a controlled length of time and subsequently providing the attachment and receptive layers on the optically active layer.

Abstract: Method for detecting the presence or amount of an analyte of interest in a sample by providing a substrate having an optically active surface exhibiting a first color in response to light impinging thereon, and exhibiting a second color comprising a combination of wavelengths of light different from the first color or comprising an intensity of at least one wavelength of light different from the first color, in response to the light when the analyte is present on the surface in an amount selected from any one of 0.1 nM, 0.1 ng/ml, 50 fg, 2.times.10.sup.3 organisms comprising the analyte; and contacting the optically active surface with a sample potentially comprising the analyte of interest under conditions in which the analyte can interact with the optically active surface to cause the optically active surface to exhibit the second color when the analyte is present.

Abstract: Optical assay device having an active receptive surface supported on a pedestal and held within a first container; the first container comprising first absorbent material located at the base of the pedestal, configured and arranged to absorb liquid draining from the surface, and having a second container, hingedly connected to one side of the first container, the second container comprising a second absorbent material, wherein the second container can be closed to the first container by rotation about the hinge, and wherein such closing causes the second absorbent material to contact the surface.
