Development of a multi-axial load distribution measurement device
… one at greater risk for ulceration. Clinical measurement of plantar pressure distribution, therefore, is commonly used to identify feet at risk of ulceration. However, plantar pressures are poor predictors and there is evidence that shear load is at least equally important in ulcer …

Design of a measurement device for bread dough proofing
… proofed. This research work seeks to design a device that quantitatively measures the dough's level of proofing and identifies when the dough is optimally proofed and ready for baking. By using a precise measurement for dough structure, the non-industrial baker can then adapt to any variable …

An exploration of through-the-eye intraocular pressure measurement device
… essential in the treatment of glaucoma, the IOP measurement techniques described in patents and patent applications since 1950 are examined. None of the methods provides a simple and comfortable approach for patients to self monitor their IOPs at different times throughout the day. A …

Determining phosphate levels in natural water using a novel electrochemical measurement device
Current measurement of the phosphorus level in natural water are based on the phosphomolybdenum blue (PMB) method. In this method, the phosphate and molybdate ion form 12-molybdophosphoric acid (12-MPA) which is reduced to yield intensely coloured PMB, and its intensity is correlated with the …

High Accuracy Real-time GPS Synchronized Frequency Measurement Device for Wide-area Power Grid Monitoring
… The FDR works as a sensor, which performs local measurements and transmits calculations of frequency, voltage magnitude and voltage angle to the remote servers via the Internet. Compared with its commercial counterpart Phasor Measurement Unit (PMU), FDR provides less expensive version for …

Measurement of finger coordination during a motor learning task
… are measured using a custom designed force measurement device. Many stroke patients do not fully recover hand function after a stroke. It has previously been shown that stroke subjects have an increase in finger enslavement or an increase in unintended force production between adjacent …

Implementation of a Conrad Probe on a Boundary Layer Measurement System
… on an autonomous, compact boundary layer measurement device and its first application for subsonic in-flight measurements of a swept wing boundary layer. Calibration of the Conrad probe was accomplished using two calibration functions and a non-nulling method for resolving in-plane flow …

Evaluation and Standardizing of Phasor Data Concentrators
… major blackouts. In order to isolate the fault, measurements taken at different times throughout the blackout need to be collected and analyzed. With each measurement device having its own time source, time alignment can be a quite tedious and lengthy process. The need for a new time synchronized …

Fast, accurate power measurement and optimization for microprocessor platforms
… far behind performance focused tools. Existing measurement apparata have low analog bandwidth, do not explicitly correlate power data with processor activity, and are not explained in sufficient detail to quantify uncertainty in their data. We present the design, implementation, and application …

Measurements of knee rotation in vivo - Development and evaluation of an external device
… of this work was to evaluate a newly developed measurement device, the Rottometer, for measuring knee rotation in different flexion angles with different applied torques, in order to establish the normal range of healthy knee rotation reference values and to study possible differences due to age …

Measurement and modelling of errors for relaying current transformers and voltage transformers
A measurement tool has been developed to estimate errors in relaying current transformers and voltage transformers. The tool has been developed to collect data in a substation and send it to a remote location over a telephone line. Different schemes were evaluated and tested in the laboratory. The …
