| 20120136372 | Robotic System for Laparoscopic Surgery - It comprises a supporting structure in which at least one arm is slidably attached. Each arm comprises first and second members hinged to each other. The first member is rotatably hinged to the supporting structure and it can be rotated about a longitudinal axis and the second member may receive a joint having at least two degrees of freedom for attaching a tool. The longitudinal axis of the first member is substantially perpendicular to an axis joining the first member and the second member to each other. A simplified architecture is obtained allowing for accurate and efficient spatial movement of the tool holding arm. | 05-31-2012 |

| 20110191359 | PROCESS FOR TRANSFORMING AND CONSULTING DIRECTED AND ATTRIBUTED MULTIGRAPHS BASED ON THE USE OF MAPS AND BITMAPS - The present invention establishes a process for creating a set of structures that allows efficient storage and subsequent handling. The multigraph is represented using bitmaps with element counters and mappings between values and organized bitmaps to faciliate the handling of the multigraphs. The bits in the bitmaps represent two aspects of the multigraph: 1) indexing of all the objects of the multigraph as a function of their identifiers and 2) connectivity between objects of the multigraph, whether they are vertices or edges. Mappings allow, given a value, accessing the objects of the multigraph which contain such value. Multigraph operations are solved by accessing the mappings and applying logical operations on the bitmaps. This way of representing a graph allows efficiently performing graph operations such as: inserting a vertex or an edge, inserting an attribute, acquiring the incoming and outgoing edges of an attribute, etc. | 08-04-2011 |
| 20110173152 | Method and device for detecting the On and Off states of a Parkinson patient - A method for detecting the on and off states of a Parkinson patient, including obtaining inertial data from a patient and verifying if the patient is in an on or off state by using a transformation of the obtained inertial data which uses a model derived from a set of stored data referred to patients in on state and patients in off state. | 07-14-2011 |
| 20110109877 | METHOD AND SYSTEM FOR THE OBJECTIVE MEASUREMENT OF OCULAR ACCOMMODATION - The invention relates to a method and system for the objective measurement of ocular accommodation. A double-pass ophthalmoscopic system is used which incorporates a periscope allowing the patient to binocularly see real objects in an open field and images of the retinal plane to be recorded on a CCD camera. The method includes obtaining, for different values of accommodation stimulation, a set of retinal images corresponding to different focal values in the retina, obtaining the different focal positions in the retina by moving the two lenses incorporated in the ophthalmoscopic system. The image with the best optical quality is obtained for each set of images and by associating the selected image with the known value of the accommodation stimulation it is possible to objectively measure the accommodation. | 05-12-2011 |
| 20110100797 | PROCEDURE FOR OBTAINING FILMS OF INTERMEDIATE BAND SEMICONDUCTOR MATERIALS - This invention describe a process for obtaining thin films of intermediate band semiconductor materials consisting of obtaining a target of compressed particles of the said material for its use in sputtering equipment. The target is obtained by means of the thermal process of a mixture of semiconductor material components, following a specific profile of temperatures and times, in order to obtain a material in a polycrystalline form of the same composition as the intermediate band semiconductor material. The polycrystalline material is disintegrated again by means of mechanical processes in the form of a powder and is then compacted, through the application of a suitable pressure in order to form a target. | 05-05-2011 |
| 20110092759 | MOBILE SYSTEM FOR ELECTRON BEAM INTRAOPERATIVE RADIATION THERAPY - A mobile system for electron beam intraoperative radiation therapy uses a race-track microtron placed in a housing playing the role of the vacuum chamber, which is supported by a positioner providing its motion with six degrees of freedom with respect to a patient. The positioner is a part of a mobile mechanical structure which houses an ion pump, a microwave source, waveguide elements, a modulator with a pulse transformer and a cooler. The intraoperative radiation therapy system has a tube-like unit which couples the vacuum chamber with the mobile supporting mechanical structure and provides three functions, namely pumping out of the air from the vacuum chamber, feeding of the race-track microtron accelerating structure with radiofrequency power and rotation of the vacuum chamber with respect to the horizontal axis of the unit. | 04-21-2011 |

| 20100277199 | System For Diagnosing Defects in Electric Motors - The invention relates to a device for the diagnosis of flanges in tri-phase motors. More specifically, the invention relates to a device comprising means for the inductive acquisition of currents in a common mode for the simple and practical diagnosis of the defects in the flanges of a tri-phase motor. The invention also relates to a current-measuring device comprising means for capturing currents by inductive methods. The invention further relates to a device and a method for detecting defects in alternating-current electric motors, and more specifically, to a device and a method for obtaining parameters relating to the possible defects in an electric motor, in order to carry out a reliable diagnosis of the defects during the normal operation of the motor. | 11-04-2010 |
| 20100195876 | SYSTEM AND METHOD FOR MEASURING LIGHT SCATTERING IN THE EYEBALL OR EYE REGION BY RECORDING AND PROCESSING RETINAL IMAGES - The invention relates to a system and method for measuring light diffusion in the eyeball or eye region, by recording and processing retinal images. The inventive system includes a double-pass ophthalmoscopic system having means for correcting low-order aberrations. Said system can be used to record images of the plane of the retina on a CCD camera, the outer part of said images containing information relating to ocular scattering. The aforementioned images can be used to obtain the objective scattering index (OSI), providing the ratio between the energy on the outer part of the image and the energy in the central part, or, alternatively, the modulation transfer function (MTF) area can be used for this purpose once the low frequencies have been filtered. According to the inventive method, the low-order aberrations are corrected before a retinal image or a temporal sequence of retinal images is captured and recorded. | 08-05-2010 |
| 20100143564 | PROCESS FOR THE PRODUCTION OF FROZEN FOODS, PARTICULARLY VEGETABLES OR FRUITS - A process for the production of frozen foods, particularly vegetables or fruits, including the stages of subjecting the food to a slight and slow dehydration, preferably by air convection, to partially eliminate its water content by between approximately 2 and 10% by weight, especially its outermost layer; allowing the food to rest to favor the redistribution of the free water contained therein and subjecting the food, after its packaging, to a rapid convection freezing treatment, either by immersion in an aqueous solution of salts or by the use of liquid nitrogen. In the case of chopped fruits, before the dehydration stage the portions are sprayed with an antioxidant product. | 06-10-2010 |
