The invention consists in structuring scintillation radiation detectors as Photonic Bandgap Crystals or 3D layers of thin filaments, thus enabling extremely high spatial resolutions and achieving virtual voxellation of the radiation detector without physical separating walls. The ability to precisely measure the recoil electron track in a Compton camera enables to assess the directions of the gamma rays hitting the detector and consequently dispensing with collimators that strongly reduce the intensity of radiation detected by gamma cameras. The invention enables great enhancements of the capabilities of gamma cameras, SPECT, PET, CT and DR machines as well as their use in Homeland Security applications. Methods of fabrication of such radiation detectors are decribed.

A security paper indicates exposure to a solvent by a solvent resistant color signal. A metal mordant dye first co-reactant and a mordant dye second co-reactant form an organic solvent-insoluble colored reaction product when the paper is washed with an organic solvent. The metal mordant dye first co-reactant and a mordant dye second co-reactant are chemically isolated from each other so as to prevent the coordinate covalent bond from forming until the paper is washed with an organic solvent. The chemical isolation can be effected by encapsulation or other physical separation of the co-reactants. The organic solvent-insoluble colored reaction product, once formed, remains entrapped in the web when the paper is washed with an organic solvent. The chemical isolation prevents the organic solvent-insoluble colored reaction product from forming upon the application of pressure alone to the paper.

In an exemplary embodiment, a stylus operates with a capacitive touch screen only when the stylus tip is in contact with the touch screen. The stylus is used as a sensor to determine the location where a user is touching the surface of a capacitive touch screen, but is not active until the stylus tip is pressed against the touch screen. In an exemplary embodiment, pressing the stylus tip against the touch screen activates the stylus by creating a physical separation in the circuit and disconnecting the stylus tip from ground. When the stylus tip is no longer grounded, it becomes active and is able to operate with a capacitive touch screen. In an exemplary embodiment, signal attenuation may be performed by diverting the sense signal to ground via a capacitor or other electronic component.

The invention belongs to the technical field of lithium ion batteries and particularly relates to a membrane for a lithium ion battery, which is good in safety performance and mechanical performance. The membrane for the lithium ion battery comprises a porous membrane substrate, a ceramic material layer coated on the surface of the porous membrane substrate, and a polymer sticking layer which is coated on the ceramic material layer and is located on the surface layer. Compared with the prior art, the ceramic material layer can form a microcosmic physical separation on the surface of the membrane so as to reduce the piercing effect of a lithium pine-tree crystal on the membrane; the ceramic material layer coated on the porous membrane substrate can improve the heat resistance of the membrane; the polymer sticking layer which is coated on the ceramic material layer and has a sticking effect can be used for preventing an inner short circuit caused by staggering of the membrane and an electrode, so that the safety performance of the battery is enhanced. In addition, the membrane, an anode sheet and a cathode sheet are joined together through the effect of the polymer sticking layer, so that the mechanical performance of the battery can be enhanced. Furthermore, the invention further discloses the lithium ion battery containing the membrane.

A process for the fractionation of valuable fractions from cereal brans (e.g. wheat, barley and oat brans, and rice polish) is described. In particular, this invention describes a two step process, in which the said bran is first subjected to a combination of enzymatic treatment and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main bran factions, i.e. insoluble phase (pericarp and aleurone layer), germ-rich fraction, residual endosperm fraction and soluble sugars. A second step consists of fractionating cereal brans substantially free of soluble compounds, hence insoluble phase from the above-mentioned first step, by enzymatic treatment with xylanases and/or beta-glucanase and wet milling, followed by sequential centrifugation and ultrafiltration, which aims at physically separating the main fractions, i.e. insoluble phase (remaining cell wall components), protein-rich fraction, soluble hemicellulose and oligosaccharide, and therefore maximizes the extraction rate of valuable cell wall components and aleurone cells from previously cleaned bran.

An apparatus and method for shielding non-target tissues and organs during thermotherapy, brachytherapy or other treatment of a diseased target tissue. The apparatus includes a catheter shaft having input and output lumens and at least one inflatable balloon. A plurality of input lumens within the catheter shaft allows the passage of liquid or gas through an input port and into the interior of the balloon thereby inflating the balloon. The gas or liquid can then be cycled through the inflated balloon through an output port and output lumen and out of the catheter shaft. Temperature sensors or other sensors may be attached to the balloon or catheter to monitor temperature or other conditions at the treatment site. The catheter is positioned between the target tissue or organ and sensitive non-target tissues in proximity to the target tissue and inflated causing a physical separation of tissues as well as a physical shield.

A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterfication process, may proceed by the addition of a mineral or an organic acid.

A broadband optical via provides a low loss interconnection between waveguides in two vertically adjacent planar waveguiding layers. Two waveguides, one in each planar layer, evanescently interact over an interaction length, and substantially all of the power on one waveguide is transferred to the second waveguide. The relative detuning between waveguides is varied along the interaction region by tapering the width of one or both guides along the direction of propagation. The interaction strength is also varied by varying the physical separation between the two waveguides such that the interaction approaches zero near the two ends of the interaction length. The performance of the broadband optical via is fabrication tolerant, polarization tolerant, wavelength tolerant, and dimensionally tolerant.

An automatic system is provided for alerting ground personnel as to the existence of a threat to commercial aircraft in which the threat is determined by a classified system, but in which the local area network employed by the military missile warning is isolated from an unclassified local network coupled to the aircraft's transponder which transmits the threat existence and status to ground personnel. The barrier to transmitting classified information involves both filtering between the classified LAN and unclassified LAN, the use of only discrete signaling lines in the classified LAN isolated by opto-electronics to provide physical separation between the two local area networks, and communications formatting which precludes the transmission of classified information across the barrier between the classified local area network and the unclassified local area network.
