The equipment should be synchronized with a cathodic protection system through a GPS antenna. It should perform high-speed analog measurements and log the synchronized data.

In recent years, it has become common practice for Mexican companies to acquire replacement machinery from other countries. Important production processes are often running with machines that are mostly outdated, require maintenance, do not have available replacement parts, and represent a monetary risk in the absence of solutions to address stoppages or unexpected failures. The plastics industry and its transformation has had sustained growth that has generated many new providers who dramatically increased the competitiveness of the sector. Add-ons to plastics products, such as hot-stamping decoration, are becoming the differentiating factor for many companies.

El equipo, mediante la manipulación de un microscopio digital, genera automáticamente reportes con los datos de la instrumentación e imágenes con sus medidas dimensionales.

Based on the relationship between lung volume and pleural pressure, we hypothesized that the time delay (∆t) between the start of a respiratory cycle and the occurrence of lung sounds associated with inspiration would correlate with lung volume. Additionally, we developed a research tool, consisting of a respiration belt, digital stethoscope, data collection system and MATLAB algorithm, to measure this delay. We conducted a feasibility study with three healthy individuals that involved safely manipulating lung volume, through subject position and activity, and plotting ∆t against volume measurements obtained via spirometry. The results indicated that ∆t was measurable and changed with lung volume and, therefore, has the potential to serve as a lung condition monitoring tool. Clinical Relevance-Developing this metric and measurement method into a noninvasive monitoring tool would provide means to better detect declining pulmonary function and intervene earlier and more appropriately.
