Abstract: The invention relates to a system of self-adjusting straps that allow the weight or load contained in the element-holding object, such as a briefcase, backpack or suitcase, to be distributed evenly and automatically over the user's two shoulders, ensuring that the object is perfectly balanced and that it fits ergonomically on the user's back. The invention also to a rear protection mechanism with a magnetic opening system, intended for objects used to hold elements, such as, for example, briefcases, backpacks or suitcases. The mechanism acts an anti-theft system for rear, side and/or lower pockets on said objects. The rear mechanism with a magnetic opening system comprises flaps with non-visible magnets located inside said flaps, which, upon coming into contact with other magnets located on the rear surface of the object, generates an attraction that secures the flaps.

Abstract: A power supply including an input configured to receive input power, an output configured to provide output power to a load, at least one relay, a crowbar circuit configured to selectively divert the input power away from the load, and a controller configured to detect a high-voltage condition at the input, activate, in response to detecting the high-voltage condition at the input, the crowbar circuit to divert the input power away from the load, output, in response to detecting the high-voltage condition at the input, a signal to operate the at least one relay to transition from a first state to a second state, and deactivate the crowbar circuit in response to a determination that the at least one relay has transitioned to the second state.

Abstract: The invention relates to a rear protection mechanism with a magnetic opening system, intended for objects used to hold elements, such as, for example, briefcases, backpacks or suitcases, said mechanism acting as an anti-theft system for rear, side and/or lower pockets on said objects. The rear mechanism with a magnetic opening system (positioned against the user's body) consists of flaps with non-visible magnets located inside said flaps, which, upon coming into contact with other magnets located on the rear surface of the object, generate an attraction that secures the flaps, such as to prevent third parties from gaining access to pockets on the outside of the briefcase, backpack or suitcase. The invention also relates to a system of self-adjusting straps that allow the weight or load contained in the element-holding object.

Abstract: A method of forecasting well production in an accurate and computational cost-efficient manner implementing a hybrid, iterative approach which is computationally efficient, numerically stable, and improves the accuracy of results. The iterative method of forecasting well production can estimate a set of scaling factor, determining the average adjusted pressure in the matrix, conductive reservoir volume, and oriented hydraulic fracture, applying an algorithm to convert the average adjusted pressure to an actual average pressure, using actual average reservoir pressure to estimate a new set of scaling factor, estimating a relative error based upon the new scaling factor, determining if the relative error is within a user-defined tolerance, and performing the above steps again if relative error is not within the user-defined tolerance or storing the new scaling factors. The new scaling factors can be used to determine a production rate.

Abstract: A recursive method of optimizing rate of penetration while drilling a well. The method can include collecting historical data on a plurality of drilling parameters, performing a mathematical analysis on the historical data to correlate each drilling parameter to a rate of penetration, determining an importance of each drilling parameter, establishing an operating envelope for each drilling parameter, and adjusting at least one drilling parameter to achieve a desired rate of penetration. The steps can then be repeated at a user defined interval.

Abstract: A control system for controlled access to a user by means of verifying a physical element defined in an optical and low level of power context, which includes: a setup (1) for the creation of arbitrary spatial light patterns, with control of amplitude and phase; which includes: a source of light (9) which emits a Laser beam; toward a first microscope objective (11); a spatial light modulation set (2) which receives the light of the first microscope objective (11) and said spatial light modulator set (2) sends a profile modulated in amplitude and phase which form an image to a beam splitter BS (17) which divides the image into an initial CCD camera (6) and to a second microscope objective (12); a defined physical element (7) which receives the initial image from the second microscope objective (12), and transmits the image without diffracting it as a final image to a third microscope objective (13); a final CCD camera (8), that receives the final image of the third microscope objective (13) and sends it to a c
