Patent number: 9377017Abstract: A pump comprising a pump housing member having a chamber with inner walls and an open end having a first area, the pump housing member comprises an enlarged surface surrounding the open end of the chamber. The pump further comprises a second pump housing member and a membrane element with a second area. The membrane element has a first central section having a third area with same size as the first area of the open end of the chamber. The membrane element is arranged on the pump housing element with the first central section positioned over the open end, forming a sealed chamber. A portion of the membrane element is slidably clamped between the enlarged surface and the second pump housing member.Type: GrantFiled: November 15, 2013Date of Patent: June 28, 2016Assignee: SHENZHEN MINDRAY BIO-MEDICAL ELECTRONICS CO., LTD.Inventors: Johan Werner, Joakim Gabrielsson

Patent number: 9360004Abstract: A pump comprising a membrane element and a pump housing having a chamber with a bevelled inner wall. The chamber comprises an open end having a third area. The membrane element has a first area, and comprises a central section with a second area which is surrounded by a periphery section. The central section is thicker than the periphery section. Further, the second area of the central section is smaller than the third area of the open end of the chamber and the membrane element is arrangable over said pump housing forming a sealed chamber, whereby the central section of the membrane element is arranged over the open end, and the central section is protruding away from the chamber.Type: GrantFiled: November 15, 2013Date of Patent: June 7, 2016Assignee: SHENZHEN MINDRAY BIO-MEDICAL ELECTRONICS CO., LTD.Inventors: Johan Werner, Joakim Gabrielsson

Publication number: 20140134019Abstract: A magnetic circuit for a voice coil, comprising, a magnet cup with a one sided open cylindrical shape with a base. The magnetic circuit further includes a conical magnet with a side including a partial conical shape. The magnetic circuit includes a pole shoe which has a side with a recessed conical shape corresponding to the conical shape of said magnet. The magnet cup, the conical magnet and the pole shoe are stacked so that the conical magnet is centrally arranged on the base inside said magnet cup, the pole shoe is arranged on the conical magnet so that the side with a recessed conical shape of the pole shoe is in contact with the side with a conical shape of the conical magnet, such that an air gap is obtained between an inner wall surface of the magnet cup and the stacked conical magnet and the pole shoe.Type: ApplicationFiled: November 15, 2013Publication date: May 15, 2014Inventors: Johan Werner, Joakim Gabrielsson, Torbjorn Boxell

Patent number: 4053947Abstract: In a computer which includes function units interconnected by a bus system there is a first type of instruction which selects one function unit and orders the performance of an internal function and a second type of instruction which selects two function units for the interchange of data through the bus system and orders the data receiving function unit to perform an internal function using the transferred data. The execution period of the second instruction type has a first part during which the first function unit is ordered to transmit data, a second part during which the data are transferred to the bus system and a third part during which the other function unit receives the transferred data. The design of the bus system makes possible the simultaneous performance of the second and third parts. The instructions are successively obtained by a fixed-cycle reading of an instruction memory and are transferred therefrom through the bus system to the function units.Type: GrantFiled: April 30, 1976Date of Patent: October 11, 1977Assignee: Telefonaktiebolaget L M EricssonInventors: Karl-Johan Werner Carlsson, Erik Ivar Sjoqvist
