20120282478 | METHOD AND APPARATUS FOR THE MULTI-LAYER AND MULTI-COMPONENT COATING OF THIN FILMS ON SUBSTRATES, AND MULTI-LAYER AND MULTI-COMPONENT COATINGS - The present invention pertains to a process for depositing multi-component and nanostructured thin films. Various parameters are monitored during the process to produce the structure of the thin films, on one hand the residence time of the gas mixture in the reactor is controlled by the pumping rate, on the other side to generate the plasma direct current (DC) or radio frequency (RF) sources are used, plus the combination of three unbalanced magnetrons allows alternative emission of elements that make up the multi-component and nanostructured films. The process is monitored by an optical emission spectrometer (EOE) and a Langmuir probe (SL), the EOE can follow the emission corresponding to the electronic transitions of atoms and molecules in the plasma. Emissions occur in the visible, infrared and ultraviolet domains. The relationships between spectral networks of different elements have been identified that ensure structural characteristics of thin films. Through SL, operating conditions have been identified by measuring the electron temperature and measuring the density of electrons. It was decided in the prototype to make this measurement at significantly important points in the process. | 11-08-2012 |
20110008054 | MODULATOR AND DEMODULATOR FOR A DIFFERENTIAL OPTICAL MODULATION FORMAT WITH EIGHT PHASE CHANGES - The invention relates to a system comprising an optoelectronic modulator device and demodulator device for establishing communication between optical communication systems by means of differential modulation with eight phase changes. Said system can increase the information transmission capacity by up to three times that of a system with two phase changes. The modulation formats transmittable by the system are called: NRZ-D8PSK, RZ-D8PSK, D8PSK. The invention also relates to the design of the modulator which is formed by a differential modulation precoder and optical signal phase modulators, in which the signals leaving the precoder control the phase modulators in order to perform differential modulation with eight phase changes in relation to the optical signal originating from a semiconductor laser. The invention further relates to the design of a demodulator positioned at the terminal end of the communication system, formed by three receiver branches each containing different electronic devices used for the electronic processing of the signals received. | 01-13-2011 |
20100234761 | BONE BIOPSY AND BONE MARROW ASPIRATION DEVICE - The invention relates to a device for taking a liquid bone marrow sample (aspiration) and a solid bone sample (biopsy) in the same procedure, which can thus replace specialized needles for taking bone marrow and needles exclusively used for taking bone biopsies. The device for taking liquid bone marrow samples and a solid bone sample has a simple mechanism that uses two grooved clamps, it is easy to disassemble for sterilization and its handle is designed to perform the puncture easily. The needle of the device is hollow, and within it a guide is placed with two sections of different diameters. The guide makes it possible to open up the empty needle channel to allow the bone marrow liquid to flow and be extracted, and also to close the channel to be able to penetrate the tissue. The purpose of this invention is to combine the procedures of bone marrow aspiration and bone biopsy, thus reducing the patient's discomfort and the time needed for the procedure. | 09-16-2010 |
20100224183 | Flat Vacuum Solar Collector Having Chamber-Type Heads - The invention relates to a flat solar collector comprising individual vacuum chambers. The invention is formed by two heads and a series of parallel tubes having high transmittance in the solar spectrum, which is disposed between said heads. The opposite side of the heads is provided with vacuum chambers which closure the connections of the conducting tubes. One of the vacuum chambers is characterized in that it is fitted with a vacuum valve at one end thereof. In addition, conducting tubes are disposed inside the aforementioned tubes having high transmittance in the solar spectrum and said conducting tubes are in turn connected to collector plates, all under vacuum conditions which minimize convection energy losses. When the conducting tubes are configured in series, the collector can raise the temperature of the working fluid to above 200° C. All of the above is performed in a novel, simple and economical manner. | 09-09-2010 |

20090306799 | Mechatronic system and method for positioning bolts in order to provide a frame with a reconfigurable surface using memory effect actuators - The invention relates to a reconfigurable computer-controlled system based on the positioning of bolts. A greater density of bolts per unit area increases the variety of figures or shapes that can be defined by a frame or tool used in the industry, such that it is no longer necessary to construct rigid surfaces with each change made to the shape of the product to be produced or surface to be formed. The use of the memory effect material as an actuator in the reconfigurability mechanism is the key to the success of the reconfigurable system and the control system owing to the permissibility of small bolts which can be adapted to standard sizes and shapes. The invention also relates to the application of the mechatronic system which uses the positioning of bolts for the reconfigurability of surfaces in order to manufacture and shape materials. | 12-10-2009 |
