v ENVIRONMENTAL SENSOR AND METHOD OF OPERATING THE SAME By www.freepatentsonline.com Published On :: Thu, 22 Jun 2017 08:00:00 EDT A gaseous-fluid environmental sensor having a gaseous-fluid flow system that defines a flow path coupling an intake port to an exhaust port. The gaseous-fluid flow system includes a blower and a flow sensor. The blower includes a motor and the flow sensor is for sensing a flow parameter. The gaseous-fluid environmental sensor further includes a controller electrically coupled to the flow sensor and the motor. The controller is configured to drive the motor with a first commutation sequence and to drive the motor with a second commutation sequence different than the first commutation sequence. The controller is further configured to select the first commutation sequence and the second commutation sequence based on the sensed flow parameter. Also discloses is a method for controlling the gaseous-fluid environmental sensor. Full Article

v Electrical Control Valve for an Air Conditioning Compressor By www.freepatentsonline.com Published On :: Thu, 29 Jun 2017 08:00:00 EDT A control valve for an air conditioning compressor is disclosed. The control valve comprises a control piston, an electric motor, a sensor, and a control unit. The control piston connects a refrigerant flow between a high-pressure area and a crankcase pressure area of the air conditioning compressor in a first position. The control piston further connects the refrigerant flow between the crankcase pressure area and a low-pressure area of the air conditioning compressor in a second position. The electric motor moves the control piston between the first position and the second position. The sensor determines the position of the control piston. The control unit is connected to the sensor and the electric motor. The control unit controls the electric motor to move the control piston and control the refrigerant flow based on the position of the control piston determined by the sensor. Full Article

v Integrated processes for refining syngas and bioconversion to oxygenated organic compound By www.freepatentsonline.com Published On :: Tue, 21 Apr 2015 08:00:00 EDT Integrated processes are provided for syngas refining and bioconversion of syngas to oxygenated organic compound. In the integrated processes ammonia contained in the syngas is recovered and used as a source of nitrogen and water for the fermentation. The integrated processes first remove tars from syngas by scrubbing using a first aqueous medium under conditions that ammonium bicarbonate is unstable. With tars removed, contact between the syngas and a second aqueous medium enables ammonia and carbon dioxide to be removed from the syngas without undue removal of components adverse to the fermentation, processing or oxygenated product such as benzene, toluene, xylene, ethylene, acetylene, and hydrogen cyanide. At least a portion of the second aqueous medium is supplied as a source of water and ammonia for the fermentation. Full Article
