Title: Apparatus for producing powder from biomaterials
Inventor: KUDRA TADEUSZ
IPC: F26B3/092
Filed: 2003-09-04
Abstract: A jet spouted fluidised bed drier is described in which the bottom half of the drier chamber comprises a first lower conical part, and the top half of the drier chamber comprises a second upper conical part surrounding a conical grid located near to the top end of the second part. The drier chamber thus comprises two conical parts connected together at their wide ends. The result of this arrangement is that the collision zone becomes a toroid with an essentially triangular cross-sectional shape defined essentially by the conical internal surface of the top part and the conical outer surface of the conical grid. This revised structural arrangement has been found to be able to process materials which either cannot be processed, or cannot be processed efficiently, with known jet spouted fluidised bed driers. Additionally, this revised structural arrangement has been found to be able to process materials more efficiently, and to a lower desired final liquid content values.

IPC: G01N21/35
Filed: 2002-03-13
Abstract: A device and a method for measuring body fluid-related metrics using spectrophotometry to facilitate therapeutic interventions aimed at restoring body fluid balance. The specific body fluid-related metrics include the absolute volume fraction of water in the extravascular and intravascular tissue compartments, as well as the shifts of water between these two compartments on the absorbance of water and the sum of the absorbances of non-heme proteins, lipids and water in the difference between the fraction of water in the intravascular fluid volume ("IFV") and extravascular fluid volume ("EFV") compartments are also determined using a differential method that takes advantage of the observation that pulsations caused by expansion of blood vessels in the skin as the heart beats produce changes in the received radiation at a particular wavelength that are proportional to the difference between the effective absorption of light in the blood and the surrounding tissue. This difference, integrated over time, provides a measure of the quantity of the fluid that shifts into and out of the capillaries. A mechanism for mechanically inducing a pulse is built into the device to improve the reliability of measurements of IFV-EFV under weak-pulse conditions.

A qubit can be initialized by grounding the qubit and applying a current across the qubit in a selected direction for a time sufficient that the quantum state of the qubit can relax into the selected state. In some embodiments, the qubit can be initialized by grounding the qubit and applyin g a current across the qubit in a selected direction and then ramping the current to zero in order that the state of the qubit relaxes into the select ed state. The states of two qubits can be entangled by coupling the two qubits through a switch. In some embodiments, the switch that is capable of groundi ng the qubits can also be utilized for entangling selected qubits.

Title: Method and apparatus for assay based on light diffraction
Inventor: LOO RICHARD
IPC: G01N33/543
Filed: 2002-09-13
Abstract: The present invention relates to a method and apparatus for detecting analytes in a medium, and more particularly the present invention relates to an assay based on light diffraction which appears or changes upon the binding of analytes to their specific receptors laid out in patterns on a substrate, which has high sensitivity due to the appropriate choice of such patterns. The present invention is based on the principle that the pattern of recognition elements, which gives rise to the diffraction of the incident light in a diffraction-based assay, can be chosen in such a way so as to facilitate detection, and to enhance the signal to be detected compared to known gratings such as parallel straight lines. In one aspect the substrate itself has a surface topography designed to enhance the diffraction pattern signals. In another aspect the substrate is a diffractive optic element having the analyte-specific receptors affixed to the optic element. In another aspect the diffractive optic element is used as a master stamp for producing patterns of analyte-specific receptors which give the signal enhancements.
