Patent number: 9758369Abstract: A manufacturing method for a MEMS element, by which both a microphone including a microphone capacitor and a pressure sensor including a measuring capacitor are implemented in the MEMS structure. The components of the microphone and pressure sensor are formed in parallel but independently in the layers of the MEMS structure. The pressure sensor diaphragm is structured from a first layer, which functions as a base layer for the microphone diaphragm. The fixed counter-electrode of the measuring capacitor is structured from an electrically conductive second layer which functions as a diaphragm layer of the microphone. The fixed pressure sensor counter-element is structured from third and fourth layers. The third layer functions in the area of the microphone structure as a sacrificial layer, the thickness of which in the area of the microphone structure determines the electrode distance of the microphone capacitor. The microphone counter-element is structured from the fourth layer.Type: GrantFiled: April 14, 2016Date of Patent: September 12, 2017Assignee: Robert Bosch GmbHInventors: Florian Schoen, Bernhard Gehl

Patent number: 9758370Abstract: Systems and methods are disclosed for manufacturing a CMOS-MEMS device. A partial protective layer is deposited on a top surface of a layered to cover a logic region. A first partial etch is performed from the bottom side of the layered structure to form a first gap below a MEMS membrane within a MEMS region of the layered structure. A second partial etch is performed from the top side of the layered structure to remove a portion of a sacrificial layer between the MEMS membrane and a MEMS backplate within the MEMS region. The second partial etch releases the MEMS membrane so that it can move in response to pressures. The deposited partial protective layer prevents the second partial etch from etching a portion of the sacrificial layer positioned within the logic region of the layered structure and also prevents the second partial etch from damaging the CMOS logic component.Type: GrantFiled: October 31, 2016Date of Patent: September 12, 2017Assignee: Robert Bosch GmbHInventors: John Zinn, Brett Diamond, Jochen Hoffmann

Patent number: 9758413Abstract: A process for treating contaminated water has the steps of filtering the contaminated water through a filter so as to produce a filtrate therefrom, introducing nutrients and a biomass into an interior volume of the of a light reactor, passing the filtrate into the light reactor, reacting light with the nutrients and the biomass so as to produce a light-reacted biomass, transferring the light-reacted biomass to a dark reactor, reacting the transferred light-reacted biomass with carbon dioxide in the dark reactor, and filtering the reacted biomass from the dark reactor so as to remove the biomass therefrom. The nutrients in the biomass are continuously stirred within the light reactor in a toroidal circulation pattern.Type: GrantFiled: June 17, 2013Date of Patent: September 12, 2017Assignee: MISSING LINK TECHNOLOGY, LLCInventor: Samuel L. Shepherd

Patent number: 9758416Abstract: A wastewater treatment process that produces primary sludge and biological sludge. The system and process hydrolyzes the biological sludge in a hydrolysis reactor. The primary sludge is directed to a pasteurization unit and pasteurized. Thereafter, the hydrolyzed biological sludge and the pasteurized primary sludge are directed to an anaerobic digester where the combined sludges are subjected to anaerobic digestion.Type: GrantFiled: April 15, 2013Date of Patent: September 12, 2017Assignee: Veolia Water Solutios & Technologies SupportInventors: Richard W. DiMassimo, Soren J. Hojsgaard

Patent number: 9758418Abstract: Methods for producing a glass ribbon include drawing a quantity of molten material from a forming vessel into a glass ribbon with the forming vessel positioned within a first portion of a housing located within an upper chamber. The methods further include drawing the glass ribbon along a draw path passing through a second portion of the housing at least partially located within a lower chamber. The methods further include venting gas from an interior of housing through a wall of the second portion of the housing. In one example, the method further includes maintaining a pressure difference between the lower chamber and the upper chamber. In another example, the method includes maintaining a pressure difference between the interior of the housing and the upper chamber.Type: GrantFiled: April 6, 2016Date of Patent: September 12, 2017Assignee: Corning IncorporatedInventors: Ahdi El-Kahlout, Soongyup Lee, Yi-Ming Liu, Douglas John Tanaka
