Patent number: 10568315Abstract: The present invention consists of a collapsible trap for insects, particularly male and female Aedes aegypti mosquitoes, the trap preferably being made of card and designed for use in a domestic or commercial environment. Specifically, the present invention discloses a foldable trap for insects, particularly male and female Aedes aegypti mosquitoes, the trap being formed by a hollow, prismatic main body which comprises an upper cover and a lower cover. The hollow, prismatic main body also comprises a translucent window in one of the sides, the internal surface of which translucent window is impregnated with an adhesive for insects. An attractive mosquito bait is located inside the hollow main body. The mosquitoes, attracted by the bait, enter the trap through at least one curved interior conduit which is located inside the hollow main body and has an entrance in the upper cover and an exit inside the trap.Type: GrantFiled: November 10, 2015Date of Patent: February 25, 2020Assignee: Universidad Industrial de SantanderInventors: Luz Marina Arboleda Parra, Laura Vanessa Bueno Capacho, Héctor Julio Parra Moreno, Jonny Edward Duque Luna

Patent number: 9666403Abstract: An X-ray source, which includes a resonant cavity preferably of a cylindrical shape, is excited in a microwave mode TE11p and affected by a static and non-homogeneous magnetic field that grows longitudinally. An electron beam is injected longitudinally through one of the lateral walls of the cavity and is continuously accelerated until it reaches an energy sufficient to produce X-rays after the electrons bombard a metallic target located in the plane where they stop their longitudinal movement. The profile of the magnetic field grows in such a way that it maintains the conditions of electron cyclotron resonance along the helical paths of the electrons, The device can be used to obtain radiographic images and even produce hard X-rays.Type: GrantFiled: August 31, 2012Date of Patent: May 30, 2017Assignee: UNIVERSIDAD INDUSTRIAL DE SANTANDERInventors: Valeriy Dondokovich Dugar-Zhabon, Eduardo Alberto Orozco Ospino

Publication number: 20150043719Abstract: The present invention discloses an X-ray source which uses a rectangular cavity resonator, which is excited with a microwave TE10p mode. The present invention also can be used as a source of cyclotron radiation, using the cylindrical cavity, but carrying out some structural changes thereof to achieve this purpose. This system allows significantly increasing the energy of the electron beam by compensating the diamagnetic force by an axially symmetric electrostatic field. The electrostatic field is generated longitudinally by ring-type electrodes placed inside the cavity, preferably in the node planes of the TE11p electric field. The electrodes should be made transparent to the microwave field, such as graphite.Type: ApplicationFiled: August 31, 2012Publication date: February 12, 2015Applicant: UNIVERSIDAD INDUSTRIAL DE SANTANDERInventors: Valeriy Dondokovich Dugar-Zhabon, Eduardo Alberto Orozco Ospino

Publication number: 20140349800Abstract: The present invention consists of the use of a control rotary actuator coupled to a worm gear mechanism for changing the transmission ratio by varying the speed of the crown of the epicyclic gear mechanism. The claimed CVT is characterized by a combined mechanical system with a low power motor, which serves as a positioner. The design of the present invention is based on the use of a rotary control actuator worm gear instead of traditional continuously variable transmission pulleys or the continuously variable toroidal transmission, in order to modify the transmission ratio by varying the speed of the epicyclic crown mechanism. This continuously variable transmission does not require any clutch to vary the gear ratio or transmission throughout its operating range.Type: ApplicationFiled: August 31, 2012Publication date: November 27, 2014Applicant: UNIVERSIDAD INDUSTRIAL DE SANTANDERInventors: Carlos Rodrigo Correa Cely, Jhony de Jesus Leyva Ricardo, Gisell Bernate Izquierdo
