Granted: 2006-11-07
Abstract: The present invention is a method of preparing a high internal phase ratio emulsion without phase inversion comprising the steps of: a) continuously merging into a dispenser and in the presence of an emulsifying and a stabilizing amount of a surfactant, a continuous phase liquid stream having a flow rate R1, and a disperse phase liquid stream having a flow rate R2; and b) mixing the merged streams with a sufficient amount of shear, and with R2:R1 sufficiently constant, to form the high internal phase ratio emulsion without phase inversion or stepwise distribution of an internal phase into an external phase; wherein R2:R1 encompasses a range, the lower limit of which range being defined by a point where the volume average particle size of the high internal phase ratio emulsion begins to show an inverse dependence on R2:R1, and wherein the upper limit of which range is just less than an R2:R1 where a phase inversion of the high internal phase ratio emulsion takes place. Monodisperse submicron particles can be prepared using the process of the present invention. Useful latexes can be prepared from these high internal phase ratio emulsions.

Abstract: An artificial retina device and a method for stimulating and modulating its function is diclosed. The device is comprised of plural multi-phasic microphotodiode subunits, which, when surgically implanted into the subretinal space, may allow useful formed articifial vision to develop. One device, called an MMRI-4 (8), is configured in a flattened cubic shape and transduces light into electric currents to stimulate the retina. The MMRI-4 comprises two subunits in a PiN configuration (10a) and two subunits in an NiP configuration (10b), both present on each of the flattened sides, thereby allowing induced sensations regardless of which side faces incident light. Filter layers (20, 22) disposed on the PiN and NiP configurations allow for visible and infrared light respectively to induce currents. An Adaptive Imaging Retinal Stimulation System (AIRES), with a Projection and Tracking Optical System (PTOS), which may be worn as a headset, is also disclosed.

Abstract: An optical disc and an optical disc recording apparatus have been disclosed which provide an improved protection against undesired or illegal copying. Information on optical discs is arranged in sectors, whi ch each has an address label. The address value of the address labels increases linearly from the start of the disc or from the start of th e program area of the disc. The address labels of specific sectors, which may have an informationless content, are given different, e.g. zero, address values, which prevent copying CD-ROM discs on a standard CD-Recorder apparatus. Said address labels may be stored in the mai n data stream or e.g. the subcode channel of a CD system.

Title: Progressive image coding
Inventor: CHRISTOPOULOS CHARILAOS
IPC: H04N7/30
Filed: 1997-03-05
Granted: 2004-11-02
Abstract: A method and a transmission system for use in coding and Progressive Image Transmission (PIT), in which the transmitter at the initial stages of the transmission uses a Region Based Coding (RBC) scheme (905) in order to provide the receiver with an image of good visual quality at a high compression ratio, which the RBC is known to be able to provide. At a later stage of the transmission, when the visual quality of the RBC image is no longer superior to other compression techniques such as JPEG, the PIT switches (903) use a continuous tone compressor (907) for the further transmission, without losing the information contained in the RBC image already transmitted. Also a hybrid RBC-DCT (Discrete Cosine Transform) is used for further improving the performance of the transmission scheme, in which the image segmented by the RBC algorithm is divided into rectangular blocks, and those blocs that are fully contained inside a region of the segmented image are transmitted using predefined base functions such as DCT  base functions. Also a method for video coding using a similar scheme is disclosed.

Abstract: The invention concerns receivers for positioning by satellites. To increase the speed measurement reliability of the receiver, it is proposed that the divergence between the effected measurements on n satellite main axes (n>4) be measured and that an alarm is given if this divergence exceeds a predetermined threshold. The divergence is measured by the root mean square deviation between the computed speed vector and the speeds as measured along the main axes and projected on the computed speed vector.

Abstract: A system for determining the spatial position of a target having an active target adapted to emit energy in response to an active signal and a passive target adapted to reflect energy impinging upon such passive target from an active energy source. A common energy detector is provided for detecting both the energy emitted by the active target and the energy reflected by the passive target. A common processor is provided for determining the spatial positions of both the passive and active targets in response to the energy detected by the common detector. During a sensor cycle the spatial position of the active target is determined and during a sensor cycle the position of the passive target is determined. The sensor cycles may be interspersed or may be the same cycle to enable simultaneous determination of both the active target and the passive target during a single sensor cycle. The system also enables the determination of the spatial position and angular orientation of both a rigid object having affixed thereto active targets and/or another rigid object having affixed thereto passive targets and/or an object having affixed thereto both an active and passive targets.

Abstract: Multilayer fluoropolymer films are formed from a layer of a fluoropolymer, a tie layer and a thermoplastic layer. The tie layer is a blend of an olefin-containing polymer, preferably at least one polyolefin having at least one functional moiety, such as an unsaturated carboxylic acid or anhydride thereof, and a styrene-containing polymer. Preferably, the fluoropolymer is a chlorotrifluoroethylene homopolymer or copolymer and the thermoplastic layer is a polyethylene. The preferred styrene-containing polymer is a styrene-ethylene-butylene-styrene block copolymer. The films exhibit increased adhesion between the layers as compared to a multilayer structure in which the tie layer is formed only from the olefin-containing polymer. The multilayer films are useful in packaging applications, including pharmaceutical packaging.

Abstract: A cryogenic liquid transfer system releases stored cryogen from a bulk stora ge tank (12) to a gas supply tank (16, 26) and a dispenser tank (18. 28). The liquid cryogen (10) in the gas supply tank (16, 26) is circulated through a heat exchange (54) and the gas generated is returned to the gas supply tank (16, 26) to pressurize it. The pressurize d liquid cryogen is released from the gas supply tank (16. 26) so that it flows through a vaporizer (64). The gas produced by the vaporizer is bubbled through the liquid cryogen in the dispenser tank (18, 28) so as to raise its temperature and pressure to the level required b y the use device being serviced. Gas from the vaporizer is then delivered to the space above the liquid cryogen in the dispenser tank (18, 2 8) to create a pressure head to cause the liquid cryogen to flow to the use device. A venturi (40) is used to reduce the pressure in the bulk storage tank.
