  • Patent number: 11657213
    Abstract: The iSlidesMobile system and methods adds POWERPOINT functionalities for text objects and numerical data be inserted (sent), edited, and deleted remotely from mobile devices directly into POWERPOINT Slide Show mode. In brief, POWERPOINT presenters a) control their POWERPOINT presentation through starting and ending presentations, moving slides forward or back, and skipping slides forward or back; and b) edit the interactive slides (iSlides) included in the POWERPOINT presentation via adding, editing, and removing text objects; and perform interactive events for audience members voluntarily participation. Additionally, audience members a) follow intuitively the presentation since slides titles are listed on the mobile's screen, and b) voluntarily participate in the edition of the iSlides that the presenter has on POWERPOINT Slide Show display via sending, editing, and deleting own text objects as well as sending numerical data.

  • Patent number: 11340150
    Abstract: The invention relates to a submersible system (1) for measuring the density and/or concentration of solids in a dispersion, which can be in the form of a liquid, a mixture of multiple liquids, a suspension of solids in liquid, or a combination of these forms, inside of a reactor (11) into which gas in the form of bubbles is introduced, the system comprising: an open, pass-through gas exclusion device (4) having a tubular body (5) with a variable cross-section through which the dispersion without gas bubbles enters, the device coupling to an inlet tube (6); a scaled chamber (8) that has a means for measuring density, when the dispersion circulates between an inlet (14) of the sealed chamber (8) and an outlet (15) of the sealed chamber (8).

  • Publication number: 20210236700
    Abstract: The present invention relates to substrates and composites having dynamic, reversible micron-level luminal surface deformation including texture or geometric instabilities, e.g., surface wrinkling and folding. The surface deformation and its reversal to the original surface form or to another, different surface form, is effective to reduce or prevent surface fouling and, more particularly, in certain applications, to reduce or prevent unwanted platelet adhesion and thrombus formation. The substrates and composites include a wide variety of designs and, more particularly, biomedical-related designs, such as, synthetic vascular graft or patch designs.

  • Patent number: 10554308
    Abstract: The invention relates to a system for communication by means of visible light and to the corresponding method, where a channel for transmitting visible light has abnormal conditions, for example, in tunnels of an underground mine with a high degree of dust concentration in the atmosphere and also in rural and urban tunnels in which the fumes generated by an accident produce high concentrations of powdery material in the transmission channel. This problem is solved by using in the system a transceiver for transmitting visible light, a means for receiving visible light, and a Deep Neural Network (DNN), with a specific arrangement, proximity or distance, of ceiling-mounted transceivers formed by LEDs lamps (arrangement of the plurality of LEDs) and Digital Single Lens Reflex (D-SLR) transceivers (formed by reflex cameras in which the lens that forms the image also provides the image in the viewfinder).
