Abstract: A method of making a multilayer filter and the multilayer filter made by the method. The method includes generally two steps. The first step is to coat a layer of nanofibers on a single side or both sides of a substrate medium to obtain a composite filter medium, and the second step is to fold the composite filter medium in a serpentine fashion to form a multilayer filter. The second step may alternatively be accomplished by stacking up a number of sheets of the composite filter medium to form a multilayer filter having a structure of two layers of nanofibers being sandwiched between two layers of said substrate medium. The resulting multilayer filter produced by either method contains at least one structural unit which has two layers of nanofibers being sandwiched between two layers of the substrate medium.

Abstract: Current methods of delivering drug usually require a certain degree of human intervention. For example, a doctor, a paramedic or a patient is required to inject insulin manually when the blood sugar level becomes low. This invention provides a medical device for use with a patient for performing at least one of the functions of delivering drug and performing physical therapy to the patient. The device of this invention includes a sensor for measuring at least one parameter from the patient, an analyzer for analyzing the parameter to determine appropriate function to be carried out on the patient by said medical device, and at least one actuator to perform at least one of the functions of delivering drug and performing physical therapy.

Abstract: A method for quantifying an intention of movement of a user, the method comprising: extracting (61) a mechanomyogram (MMG) signal in response to surface vibration of a muscle of the user; and averaging (62) the MMG signal by calculating the MMG root mean squared (RMS) amplitude (63) or frequency variance (64) in a predetermined time window; where an increasing RMS amplitude of the MMG signal corresponds to increasing muscle voluntary contraction or a decreasing frequency variance of the MMG signal corresponds to increasing muscle voluntary contraction.

Abstract: A method for identifying, diagnosing, and monitoring cancerous lung tissues in a subject may include measuring the expression of at least one biomarker in a biological sample in the subject, and comparing the expression against a normal value. When a differential expression of the at least one biomarker between the biological sample and the normal value is more than 1.5-fold, the lung tissue sample is cancerous.

Abstract: The present invention relates to a method for microfluidic mixing in a “lab-on-a-chip” environment. The methodology focuses on constant acceleration and deceleration about a mean angular speed with a rotating disk serving as the mixing platform. The methodology results in good mixing between different fluids.

Abstract: An improved screen basket for use with a centrifuge includes two adjoining screen sections. The first screen section is formed from a wear resistant material and is located proximate to the point at which slurry is introduced into the basket. The length of the first screen section is chosen so that the majority of potential wear caused by the abrasive slurry occurs within the first section of the basket. The second screen section is preferably formed from less expensive materials, such as steel wedge wire. The second screen section smoothly joins the first screen section and provides for further dewatering or separation of the accelerated slurry so that a dry cake is produced by the centrifuge.

Abstract: In a continuous-feed filtering- or screening-type centrifuge, first dewatering a particulate material, then reslurrying the particulate material, and subsequently again dewatering the particulate material in a sequence along a cake flow path extending through the continuous-feed filtering- or screening-type centrifuge. The first dewatering, the reslurrying and the subsequent dewatering are performed in respective compartments disposed along the cake flow path. The compartments are defined in part by a plurality of gates, baffles, or weirs extending outwardly from a hub of the centrifuge. Outer ends of the gates are spaced from a bowl wall to define respective cake flow gaps which limit the thickness of a cake layer moving along the cake flow path.
