Elastomer masterbatch is processed in a continuous compounder having multiple parallel elongate rotors axially oriented in an elongate processing chamber. Optionally, additional materials are compounded into the masterbatch, e.g., additives, other elastomeric compositions, etc. Preferably, the masterbatch then is further processed in an open mill. Excellent control of Mooney Viscosity is achieved.In certain preferred embodiments, elastomer composites are produced by novel continuous flow methods and apparatus in which fluid streams of particulate filler and elastomer latex are fed to the mixing zone of a coagulum reactor to form a coagulated mixture in semi-confined flow continuously from the mixing zone through a coagulum zone to a discharge end of the reactor. The particulate filler fluid is fed under high pressure to the mixing zone, such as to form a jet stream to entrain elastomer latex fluid sufficiently energetically to substantially completely coagulate the elastomer with the particulate filler prior to the discharge end without need of adding acid or salt solution or other coagulation step. The coagulated elastomer and particulate filler composite is fed into the aforesaid continuous compounder for processing and control of its moisture level and Mooney Viscosity. Novel elastomer composites are produced. Such novel elastomer composites combine material properties and characteristics, such as choice of filler, elastomer, level of filler loading, moisture level, Mooney Viscosity, balance between molecular weight and amount of bound rubber, and macro-dispersion not previously achieved.

This specification describes techniques for fabricating connections between pairs of components. Each connection includes an array of bumps on a male component, and a matching array of wells filled with bonding material on a female component. The bump / well connections can be spaced with a pitch of less than 100 microns. One application of the invention is the attachment of electronic components to interconnection circuits or circuit assemblies to form electronic modules. The electronic components may be IC chips or high-density interconnect cables. Another application is alignment of optical components. The direct chip attachment techniques are described in the context of fabrication, assembly, test, rework, and cooling of electronic modules employing flip chip components. The preferred method is to fabricate the module on a glass carrier using a release layer so that the carrier can be removed after most of the processing is done.

Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeability. The inventive inflatable fabrics are primarily for use in automotive restraint cushions that require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessarily low permeability levels. Thus, the inventive coated inflatable airbag comprises a film laminated on at least a portion of the target fabric surface wherein the film possesses a tensile strength of at least 2,000 and an elongation at break of at least 180%. The film provides a low permeability airbag cushion exhibiting a leak-down time of at least 5 seconds as well as a very low packing volume (for more efficient use of storage space within a vehicle) for the target side curtain airbag.

An implantable vagal stimulation device with high-energy efficiency and novel data sensing is provided for use in a wide variety of applications where neural stimulation is required, including human heart rate control. The stimulation device uses low-impedance circuitry and digital waveforms to minimize energy losses, thereby requiring a relatively small battery. Front-loaded, passive filtering is employed to reduce electromagnetic noise sensitivity, leaving a clear physiological signal without degradations. This physiological signal is processed by a derivative zero transition detector (DZD), which is immune to variations in input signal dynamic range unlike traditional methods. Information that the DZD receives can be then interpreted and used along with an algorithm to execute appropriate vagal nerve stimulation.

The present invention relates to automatic registration and tracking of the eyes of at least one subject. An optical system, including a lens structure, a mask and an image sensor, receives incoming light from a scene containing the subject and directs at least a portion of this light towards the image sensor, which registers spatially distributed light and thus produces primary data. The mask is adapted to alter a basic optical transfer function of the lens structure and the image sensor into an enhanced optical transfer function, which is substantially less sensitive to variations of an unknown distance between the optical system and the subject than the basic optical transfer function. The processing unit is adapted to receive the primary data and process this data to produce resulting eye-tracking data representing a position estimate of the at least one eye and / or a gaze direction for the at least one eye.

Coated inflatable fabrics, more particularly airbags to which very low add-on amounts of coating have been applied, are provided which exhibit extremely low air permeabilities. The inventive fabrics are primarily for use in automotive restraint cushions which require low permeability characteristics (such as side curtain airbags). Traditionally, heavy, and thus expensive, coatings of compounds such as neoprene, silicones and the like, have been utilized to provide such required low permeability. The inventive fabric utilizes an inexpensive, very thin coating to provide such necessary low permeability levels. Thus, the inventive coated airbag possesses a coating of at most 3.0 ounces per square yard, most preferably about 0.8 ounces per square yard, and exhibits a leak-down time (a measurement of the time required for the entire amount of gas introduced within the airbag at peak pressure during inflation to escape the airbag at 10 psi) of at least 5 seconds as well as very low packing volumes (for more efficient use of storage space within a vehicle). All coatings, in particular elastomeric, preferably, though not necessarily, non-silicon coatings, and coated airbags meeting these criteria are intended to reside within the scope of this invention.

A self-aligned fabrication process for three-dimensional non-volatile memory is disclosed. A double etch process forms conductors at a given level in self-alignment with memory pillars both underlying and overlying the conductors. Forming the conductors in this manner can include etching a first conductor layer using a first repeating pattern in a given direction to form a first portion of the conductors. Etching with the first pattern also defines two opposing sidewalls of an underlying pillar structure, thereby self-aligning the conductors with the pillars. After etching, a second conductor layer is deposited followed by a semiconductor layer stack. Etching with a second pattern that repeats in the same direction as the first pattern is performed, thereby forming a second portion of the conductors that is self-aligned with overlying layer stack lines. These layer stack lines are then etched orthogonally to define a second set of pillars overlying the conductors.
