Compositions and methods of preparing functional thin films or surface coatings with low non-specific binding are described. The thin films contain specified functional groups and non-specific binding repellant components. The thin films are either covalently bound to or passively adsorbed to various solid substrates. The specified functional group provides specified activity for the thin film modified solid surfaces and non-specific binding repellant components significantly reduce the non-specific binding to the thin film modified solid surfaces. Non-specific binding repellant components do not affect specified functional group's activity in the thin films. In these methods, specified functional groups are anchored to the solid substrates through a spacer. Surface coatings are also described having both non-specific protein binding properties combined with functional groups for specific binding activity thereby providing surface coating that specifically recognize target proteins but limit binding to non-specific protein.

A small diameter spark plug configuration is provided, the configuration has been found to provide additional volume for the insulator member. That is, by limiting the overall number of threads on the intermediate portion along with a limit of the overall diameter of the spark plug, additional volume of insulator material may be achieved in an interior cavity of a metal shell of the spark plug. This additional volume enables a portion of the insulator member to have a larger diameter and hence greater material thickness. The larger diameter of the insulator provides enhanced dielectric properties and protects internal components of the spark plug from high combustion chamber temperatures while simultaneously providing a robust attachment of the spark plug with an engine head.

The present invention refers to hybrid anode disk structures for use in X-ray tubes of the rotary anode type and is concerned more particularly with a novel light weight anode disk structure (RA) which comprises an adhesion promoting protective silicon carbide (SiC) interlayer (SCI) deposited onto a rotary X-ray tube's anode target (AT), wherein the latter may e.g. be made of a carbon-carbon composite substrate (SUB′). Moreover, a manufacturing method for robustly attaching a coating layer (CL) consisting of a high-Z material (e.g. a layer made of a tungsten-rhenium alloy) on the surface of said anode target is provided, whereupon according to said method it may be foreseen to apply a refractory metal overcoating layer (RML), such as given e.g. by a tantalum (Ta), hafnium (Hf), vanadium (V) or rhenium (Re) layer, to the silicon carbide interlayer (SCI) prior to the deposition of the tungsten-rhenium alloy. The invention thus leverages the tendency for cracking of the silicon carbide coated carbon composite substrate (SUB′) during thermal cycling and enhances adhesion of the silicon carbide / refractory metal interlayers to the carbon-carbon composite substrate (SUB′) and focal track coating layer (CL) by an interlocking mechanism. Key aspects of the proposed invention are: a) controlled formation of coating cracks (SC) in the silicon carbide layer (SCI) and b) conformal filling of SiC crack openings with a refractory metal.

A method using optical coherence tomography to capture the microvascular network of the superficial layer of the finger skin for the purpose of fingerprint authentication and liveness detection. At the dermal papilla region, the vascular pattern follows the same pattern of the fingerprint and this vascular pattern forms a live vascular fingerprint. This live vascular fingerprint provides for ultrahigh security and a unique way for fingerprint-based personal verification. Because the system is based on blood flow, which only exists in a living person, the technique is robust against spoof attaching. After performing non-contact in-vivo imaging of a human fingertip, a three dimensional vasculature image is reconstructed from a plurality of vasculature tomography images and at least one vasculature fingerprint image which corresponds to the fingertip is extracted from the three dimensional vasculature image. This extracted image may then be compared to known fingerprint database for authentication or for liveness detection.
