Abstract: A rotating coalescer having an ejected coalesced liquid separating device is described. The separating device prevents re-entrainment of liquid into a stream of filtered gas. The rotating coalescer includes a rotating filter element or coalescing cone stack positioned within a rotating coalescer housing. The outer surface of the rotating filter element or the outlet of the coalescing cone stack is displaced from the inner surface of the rotating coalescer housing. The gap between the rotating filter element or the coalescing cone stack and the rotating coalescer housing allows for ejected coalesced liquid, such as oil, to accumulate on the inner surface of the rotating coalescer housing for drainage and allows for filtered gas, such as air, to exit through a clean gas outlet of the rotating coalescer housing.

Abstract: A inflation sealing system is provided for sealing a filter element in a housing at a mating interface therebetween. The sealing system includes a keyed interface. A replacement filter element is provided for such filtration sealing system, with the replacement filter element including a keyed interface.

Abstract: Rotating coalescer crankcase ventilation (CV) systems are described. The described CV systems utilize a pumping pressure created by the porous media of the rotating coalescer to maintain positive recirculation of filtered blowby gases through a potential leak gap between a static housing inlet and a spinning component of the rotating coalescer. In some arrangements, the porous media is fibrous media. The filter media may be pleated or non-pleated. The positive recirculation caused by the pressure balance prevents unfiltered blowby gases from bypassing the media of the rotating coalescer from the upstream side to the downstream side of the filter media through the gap. During operation, the pressure balance between the upstream side and downstream side of the filter media maintains the positive recirculation, which in turn maintains a high filtration efficiency.

Abstract: A computing network data layer architecture or system includes an open data layer module comprising a translation layer. Translation flags are within the translation layer and each flag is associated with a database language of an underlying database that can be coupled architecture or system. The open data layer module is disposed at the lowermost layer of the architecture directly above the underlying backend database. The open data layer module allows for a system to replace or modify its backend databases without affecting the higher level visualization framework or user interface such that a user of the system is unaware which database is utilized or after one database has been replaced or swapped for another even though the databases may be disparate hand have different database language requirements.

Abstract: A network system provides architecture for transmitting data across low-bandwidth links via user datagram protocol (UDP) via a scheduler that schedules, prioritizes, and collaborates data for transmission. The schedule coordinates low priority data and high priority data that may interrupt the low priority data in response to preset rules programmed into an automatic decision module. The automatic decision module may also include variable rules that can vary in response to machine learned information occurring or incoming to the system in situ.

Abstract: Receptors are selectively attached by introducing blocking materials in the areas outside the active sensor surface area, and/or selectively attaching the bio receptors to one or more active sensor surface areas. Methods for selective attachment include the use of optical attachment using a patterned exposure to assist in the creation of receptor bonding to pre-selected regions of the one or more chips. Blocking agents are attached to regions where blocking the receptor attachment is beneficial. Biased conducting regions may also affect selective attachment. Such controlled blocking may be accomplished using optical patterning exposure with optical assisted bonding of the blocking molecule or lift off processes. Patterned exposure for either attachment assists or liftoff processes employs photo masks. Conducting regions outside of the active sensor gate region are biased, affecting biochemical binding or non binding, and shielding of the semiconductor region outside of the active biosensor region.

Abstract: A new class of electronic devices suitable for Si IC incorporation and of diverse utility are described. The devices are useful for many sensing applications as well as for special circuit applications. Sensing applications include chemical and biochemical sensing, photo detection (UV, visible, IR and FIR), magnetic field sensing, electric field sensing, and force sensing. The devices are MEMs compatible. Sensor sensitivity is voltage and current tunable over a wide range. The devices further constitute a new and useful class of IC reference voltage devices. Selective non linear features are also achievable in support of non-linear device applications. These unique devices may be considered as distributed merged bipolar and FET structures. The new distributed channel bipolar devices (DCBDs) have a channel of a selected shape formed in a surface of a substrate by doping or by influencing of a coating. In the device structure, the channel acts as an NPN or PNO BJT collector or emitter.

The receptors are contacted for changing current flow between the source and the drain. The source and the drain are relatively wide compared to length between the source and the drain through the conducting channel.

This invention involves both a physical system and a methodology.

Abstract: A top incident spectrometer includes a first distributed wavelength wedge filter region of order n.sub.1 that discriminates incoming radiation as a function of wedge location, at least one second wedge region order n.sub.2 (which region may be a graded dielectric film), and an underlying detector array. In another embodiment, a second dielectric wedge element includes a Fabrey-Perot etalon, a wedge dielectric film, or a graded index film matching the second dielectric wedge region to an underlying substrate. One or more slopes associated with wedge elements may also be varied to alter filter characteristics. Spatial characteristics may further be modified by including a dielectric material whose dielectric constant varies as a function of location. Wedge filter crosstalk is minimized by partitioning a wedge dielectric region in the lateral dimension.

Abstract: A method and application for detecting and measuring the presence of a binding target material employs a semiconductor device having a receptor-covered surface topgate, separated by a dielectric layer from a substrate. Receptors attached to this surface exhibit a chemical selectivity function. Binding occurs in a test solution, with charge associated with the target material modulating at least one device characteristic. According to the present invention, measurement may occur under dry conditions, at a time and location different from when binding occurred, thus substantially eliminating problems associated with ionic shielding and reference electrodes, so prevalent with prior art wet measurement techniques. Preferably the device includes a backgate to which a bias may be applied to restore the device's pre-binding characteristics. Measurement of the restorative backgate bias provides a signal indicating binding of the desired target material.

Abstract: A stationary spindle shaft assembly supports and controllably rotates a disc pack within the housing of a magnetic disc drive. The shaft assembly includes an elongate spindle shaft fixed with respect to the drive housing, and a stator surrounding and integral with the spindle shaft. A centered, axial bore in the spindle shaft is open to one end of the spindle shaft to receive a bundle of electrically conductive lines for mechanical and electrical coupling to the stator through a printed circuit. A pair of radial apertures are formed in the shaft near the inward end of the axial bore. Each aperture is open to the bore and to the spindle shaft exterior, and accommodates approximately one-half of the conductive lines as they extend from the bore to the stator. The radial apertures are spaced apart from one another 180 degrees, such that a selected axial plane bisecting the shaft also bisects each of the apertures.
