Publication number: 20200174742Abstract: A personal monitoring system for musicians playing in a group situation, wherein each musician is allowed to change his or her own personal mix audio signals coming from the other musicians and the sound of his or her own instrument. Each musician has a personal mixer which can receive audio signals wirelessly from the remaining musicians in the group. The mixer also has a wired input for receiving the audio signal from the musician's own musical instrument. The mixer may also be configured to receive mix control commands from a mobile wireless controller device operated by the musician.Type: ApplicationFiled: November 27, 2019Publication date: June 4, 2020Applicant: HAUTE ECOLE D'INGENIERIE ET DE GESTION DU CANTON DE VAUD (HEIG-VD)Inventor: Raphael BUACHE

Publication number: 20120139676Abstract: A magnetic field generator (10) comprising an assembly (20) of permanent magnets (30) inside which the magnetic flux concentrates. The assembly comprises opposed first and second elements (21, 22) that include magnets (30). The elements (21) and (22) are arranged substantially in the same plane and surrounded by respective closing mechanisms (51, 52). The permanent magnets (30) are made up of parallelepipedal blocks, arranged substantially in an arc of a circle according to three areas: a central area (60), a first side area (70) on one side of the central area (60), and a second side area (80) on the other side of the central area (60). The permanent magnets (30) of the first and second (70, 80) side areas have opposite directions of magnetization. Two parts (91) and (92) of a ferromagnetic material, forming a magnetic flux concentrator (90), are arranged on either side of the air gap (40).Type: ApplicationFiled: June 1, 2010Publication date: June 7, 2012Applicant: HAUTE ECOLE D'INGENIERIE ET DE GESTION DU CANTON DE VAUD (HEIG-VD)Inventors: Osmann Sari, Nathanael Alber

Patent number: 8191375Abstract: A device (10) for continuously generating cold and heat by a magnetic effect. The device includes a magnetic field generator (13), which is arranged in at least one crown segment and defines an annular space crossed by a circular coaxial part (11) provided with radial transverse cavities (31) and contains at least one type of magneto-calorific material. The inventive device also includes a circulating pump (27) for axially supplying a heat carrier to the cavities (31). A first collector (33) picks up the heat carrier, which passes through the radial cavities (31) in the area containing the magnetic field generator (13), and a second collector (34) picks up the heat carrier which passes through the radial cavities (31) in an area located outside of the magnetic field generator (13).Type: GrantFiled: December 12, 2006Date of Patent: June 5, 2012Assignee: Haute Ecole d'Ingenierie et de Gestion du Canton de Vaud ( Heig-VD)Inventors: Osmann Sari, Peter W. Egolf, Stefano Bozzini

Patent number: 7481063Abstract: The device (10), for the continuous generation of cold and heat by magneto-calorific effect, comprises a mixture of a heat exchange fluid and particles made from at least one magneto-calorific material, superconductor or phase-change material circulating through a first heat exchanger (11) subject to a magnetic field generated by magnetic device (14), associated with the first heat exchanger (11). On passing into the generated magnetic field, the particles undergo an increase in temperature and heat the mixture in the first heat exchanger (11) and on leaving the magnetic field, the particles undergo a reduction in temperature to cool a mixture entering a second heat exchanger (12). A cold circuit (16) extracts the cold from the second heat exchanger (12) and a hot circuit (15) extracts the heat from the first heat exchanger (11).Type: GrantFiled: December 24, 2003Date of Patent: January 27, 2009Assignee: Haute Ecole d'Ingenierie et de Gestion du Canton de Vaud (Heig-VD)Inventors: Andrej Kitanovski, Peter Williams Egolf, Osmann Sari

Patent number: 7481064Abstract: The device (10) for continuous generation of cold and heat by the magneto-calorific effect, comprises a chamber (11), divided into two adjacent compartments (12, 13), separated by a wall (14). The chamber (11) contains a rotating element (15) made from at least one magneto-calorific material, a first circuit (17a) with a first heat exchange fluid circulating therein and a second circuit (17b) with a second heat exchange fluid circulating therein. The chamber (11) is connected to magnetic device (16) for generating a magnetic field in the region of the compartment (12) in which the rotating element (15) is located. When the above is set in rotation the part thereof located in the first compartment (12) is magnetized upon undergoing an increase in temperature. On passing into the second compartment (13), the part is demagnetized upon undergoing a cooling.Type: GrantFiled: December 22, 2003Date of Patent: January 27, 2009Assignee: Haute Ecole d'Ingenierie et de Gestion du Canton de Vaud (Heig-VD)Inventors: Andrej Kitanovski, Peter Williams Egolf, Osmann Sari
