We have developed a new system for measuring dental, gnathic, and facial areas with cephalogram-equivalent images created from computed tomographic imaging data. An advantage of this collaborative is that measurement template automated processing are used. First, experienced orthodontists were provided the templates; they then moved markers to specified landmarks on cephalogram in template. Sub...

This paper presents a 3D shape measurement system for stationary objects which features reduced cost, high accuracy, and ease of implementation. An integral part of this system is a 2D multi-plane camera calibration technique, implemented with improvements to the automation and corner extraction over traditional techniques. A binary coded structured light plus phase shifting technique is implem...

A cell-impedance measurement system is presented that can measure an effective parallel resistance and capacitance of a cell to within 1% in 1ms. It is proven to be functional at ten logarithmically-spaced frequencies between 100 kHz and 100 MHz, with ten parallel structures simultaneously calculating each of these. This system is further shown to be implementable with commercial parts – namely...

The paper describes new approach of potentiostat for very low sensor current measurements. Recent potentiostats were used as measurement devices which were standalone and sensors were connected by a screened wire. These concepts are inconvenient for the presented very low current measurements. The new approach is based on the potentiostat circuitry integrated on a chip that should be directly c...

The instrument described in this manuscript was developed to perform objective, quantitative measurements of wound healing, which will enable service providers to assess, improve, and individualize the treatment given to each wound patient. It was designed to produce measures that will enable the care provider to assess the current state of the wound as well as gain insight into the time course...

A new stiffness measurement method is proposed that utilizes the lateral deformation profile of an object under indentation. The system consists of a force measurement module between a pair of equidistant touch sensing modules. Unique feature of the method is that by adjusting the touch module separation, indenter protrusion, and spring constant of the force sensing module, one can choose a des...

Turning Point for Measurement System Although the current performance measurement system has served VA well, we are at a turning point. The Executive Career Field (ECF) plan for 2008 is the beginning of a new use of performance measurement. In 1995, when measures became a formalized part of the ECF plan by which all Senior Executives in the Veterans Health Administration are evaluated, all VA p...

A novel distributed wireless measurement system, which is consisted of a base station, wireless intelligent sensors and relay nodes etc, is established by combining of Bluetooth-based wireless transmission, virtual instrument, intelligent sensor, and network. The intelligent sensors mounted on the equipments to be measured acquire various parameters and the Bluetooth relay nodes get the acquire...
