Publication number: 20140115849Abstract: A mechanical amplifier and method for converting a small motion amplitude to a larger motion amplitude are disclosed. The method includes using two or more beams which are connected in series at angles to each other. Undesirable movements arising in the structure are absorbed by the structure through torsion. Each beam is a mechanical motion amplifier, and by connecting these in series, the total amplification is the product of the amplification of the comprised beams. The disclosure also pertains to a device comprising two or more beams connected together at an angle of 90 degrees in one embodiment.Type: ApplicationFiled: January 7, 2014Publication date: May 1, 2014Inventor: Göran Cewers

Patent number: 8393228Abstract: A method is described for measuring a flow of gas passing a flow meter device. The device causes a pressure drop when a gas flows through it. The pressure drop across the device is a measure of the gas flow. The device is configured as a gas permeable tube that has a flow channel on the upstream side along the tube configured so as to decrease the cross-section of the channel downstream of the gas permeable tube. This provides for a minimum volume in the channel upstream of the device's pressure-drop-generating component.Type: GrantFiled: May 16, 2011Date of Patent: March 12, 2013Assignee: Mindray Medical Sweden ABInventor: Göran Cewers

Patent number: 8230857Abstract: The invention pertains to a ventilator that delivers a flow of gas to an airway of a user, and to communicate a flow of gas from the airway of the user in a controlled manner. The ventilator includes a conduit (1, 3) that carries a flow of gas from the airway of a patient, a first valve (7) coupled to the conduit and adapted to control a pressure or rate of the flow of gas exhausted from the conduit, a first sensor (10) coupled to the conduit and adapted to monitor a pressure of the gas in the conduit, and a controller (12) adapted to control the first valve based on an output of the first sensor. A restrictor (8) is provided in the conduit between the pressure sensor and the patient such that a first volume is defined in the conduit between the first valve and the restrictor and a second volume is defined in the conduit between the patient and the restrictor. The controller controls actuation of the first valve based on a pressure of the first volume monitored by the first sensor.Type: GrantFiled: November 9, 2005Date of Patent: July 31, 2012Assignee: RIC Investments, LLC.Inventor: Göran Cewers

Patent number: 8161970Abstract: A system that provides a flow of gas to an airway of a user that includes a source of gas, a conduit that carries the flow of gas to the airway of a patient, a first valve that controls a pressure, flow, or volume, of the flow of gas, a pressure sensor coupled to the conduit between the valve and the patient that monitors a pressure of the gas in the conduit, and a controller that controls the valve based on an output of the pressure sensor. A restrictor is provided in the conduit between the pressure sensor and the patient that divides the fluid delivery system with a first smaller volume in the conduit between the valve and the restrictor and a second larger volume between the patient and the restrictor. The system controls the pressure, flow, or volume relative to the first volume.Type: GrantFiled: September 1, 2005Date of Patent: April 24, 2012Assignee: RIC Investments, LLCInventor: Göran Cewers
