Title: Use of ultrasound imaging equipment in classroom as a teaching aid
Inventor: HAIDER MUHAMMAD R
IPC: A61B8/00
Filed: 2008-04-21
Abstract: The inventive process named SWITCH is a unique teaching aid for students and teachers of biology to help them better understand the basic concepts and remove the ambiguities left behind by traditional teaching methods. It utilizes a portable ultrasound machine in a class room setting to obtain real time images of internal organs of human/animal body and project them on a big screen while the audience watches. The images so produced are not only vivid and multidimensional but also carry information like organ size, shape, texture, position and physical relationship to other organs in the body. In case of heart and blood vessels the real time images demonstrate exact function of chambers and valves and flow of blood in color from arterial to venous tree. The technique aims at fortifying truthful concepts of systems in a living body from the very basic to advanced levels of biology education. It has been developed in accordance with curricular guidelines for various levels and therefore has different modules dedicated to those levels (high school, colleges, universities, technical training institutes and other professional training institutions). Modules are based on chapters of respective recommended text books and can be utilized at the beginning, during or at the end of a chapter.

Abstract: A vital sign measurement device includes a sensor fixation device, an optical sensing system, and an output unit. The sensor fixation device is adapted to be placed against an anatomical location of a subject, within which is an artery. The optical sensing system includes an optical source, an optical refractor, and an optical detector, all of which are held by the sensor fixation device and move with movement of the sensor fixation device. The optical sensing system is positioned with respect to the sensor fixation device to sense movement corresponding to an arterial pulse when the sensor fixation device is placed against the anatomical location of the subject. The optical sensing system can sense an arterial pulse from the movement, bending, or compression of at least one portion of the optical sensing system relative to other portions of the optical sensing system resulting in a change in an optical signal received by the optical detector. The output unit receives, from the optical sensing system, an input indicative of movement corresponding to an arterial pulse and generates, using the input, a measure of the vital sign.

IPC: C12Q1/56
Filed: 2007-06-06
Abstract: A reliable, fast and convenient method is provided to determine the change in concentration of enzyme in time in a biological medium in the presence of a signal substrate that corrects for substrate consumption, color-dependency of the signal and non-linearity between the concentration of the leaving group of the signal substrate and the amount of signal. The method comprises the measurement of a calibrator curve in a suitable medium, such as a buffer, to determine the characteristics of the measured curve. These characteristics will then allow to obtain this whole curve or a sufficient part thereof again through a mathematical procedure based on a single-point measurement in a sample of a medium in which the enzyme generation takes place. This has the great advantage that there is no need to measure the whole calibrator curve in each individual medium, since a single-point measurement is adequate.
