Publication number: 20240043108Abstract: The technology relates to techniques for drogue deployment for a lighter than air (LTA) vehicle descent. A drogue deployment system for an LTA vehicle descent can include a drogue comprising a drogue parachute coupled to a carrier. A spring can be configured to launch the drogue from a launch tube directed outward from an apex of the LTA vehicle in an acute angle from a horizontal plane. A core can be placed around the launch tube and placed around the spring, the core compressing the spring and holding the spring in a compressed state prior to deployment, and a riser can couple the carrier to the envelope of the LTA vehicle. In some cases, the drogue deployment system can comprise two or more drogues, wherein intervals between the two or more drogues can be selected such that horizontal components of drogue deployment forces approximately cancel out.Type: ApplicationFiled: October 20, 2023Publication date: February 8, 2024Applicant: Aeorstar International, LLCInventors: Nicolas Bergeron, Adam French

Publication number: 20220076909Abstract: The technology relates to techniques for an electromagnetic inertial switch. An electromagnetic inertial switch can include an electrically conductive and magnetic mass located within a cavity, where portions of the cavity are electrically conductive and are electrically coupled to terminals of the electromagnetic inertial switch. A first magnetic field can be configured to apply a first force on the mass to attract the mass towards a first location, and a second magnetic field can be configured to apply a second force on the mass to attract the mass towards a second location. The electromagnetic inertial switch can be in a first electrical state when the mass is in the first location, and in response to an acceleration event greater than a threshold acceleration, the mass can move to the second location, thereby changing the electromagnetic inertial switch to a second electrical state.Type: ApplicationFiled: September 9, 2020Publication date: March 10, 2022Applicant: LOON LLCInventor: Nicolas Bergeron

Patent number: 9607557Abstract: An electrowetting display apparatus includes a first substrate including a first electrode that receives a gray-scale voltage and a second electrode insulated from the first electrode and receiving a reference voltage, a second substrate, a fluid layer, and a color filter. The color filter has a first thickness in an area corresponding to the first electrode and a second thickness in an area corresponding to the second electrode, and the first thickness is larger than the second thickness. Accordingly, a cell gap of the electrowetting display apparatus is reduced, and color reproducibility of the electrowetting display apparatus is improved without sacrificing brightness.Type: GrantFiled: August 18, 2014Date of Patent: March 28, 2017Assignee: Amazon Technologies, Inc.Inventors: Sanghyun Lee, Yungkyung Park, Dohyoung Kwon, Gichang Park, Jongseo Lee, Andrea Giraldo, Nicolas Bergeron

Patent number: 8730555Abstract: An electrowetting display device comprises a plurality of picture elements (2) having a first support plate (5) including a surface (68) and a second support plate. A space (10) of a picture element between the surface of the first support plate and the second support plate includes at least one first fluid and a second fluid immiscible with each other, the second fluid being electroconductive or polar. The first support plate includes an electrode (46) for applying an electric field in the picture element. It also includes a layer (44) arranged on a side of the electrode facing away from said space. The layer forms an electronic component (33) for applying a voltage to the electrode. The electrode comprises a height difference (86) corresponding to a thickness of the layer (44). The height difference causes an inhomogeneous electric field in the space, providing a preferred direction of motion of the first fluid on application of the electric field.Type: GrantFiled: June 4, 2010Date of Patent: May 20, 2014Assignee: Liquavista B.V.Inventors: Jo Aubert, Nicolas Bergeron, Roy Van Dijk, Andrea Giraldo

Publication number: 20080211999Abstract: A transflective display device has a color filter portion for each pixel which includes portions of two different thicknesses. In one implementation, both thicknesses are used for the reflective part of the pixel, and the relative thicknesses as well as the proportion of different thickness layers can be controlled to enable independent control of the color filtering characteristics in the reflective and transmissive modes of operation. Another implementation uses different portions of light absorbing material for the functions of pixel definition and height adjustment, but these may be achieved with a single patterned layer.Type: ApplicationFiled: September 15, 2005Publication date: September 4, 2008Applicant: TPO Hong Kong Holding LimitedInventors: Samuel Gu, Charles Richard Manuel Schmidgall, Nicolas Bergeron, Harrie Hermens, Wk Mok, Xy Gong
