Abstract: An ultrasonic filtration device may be incorporated into or otherwise installed in an extractor hood in a cooking environment. The ultrasonic filtration device aids in the elimination and/or reduction of contaminants in the air produced as a byproduct of cooking. Particulate contaminants are bombarded with high-energy pressure waves, thereby breaking up the particulates and reducing their size until they are no longer noticeable and/or hazardous to the user.

Abstract: A cooktop ventilation system for providing ventilation of a domestic cooking appliance, includes a domestic ventilation appliance including housing having at least a first opening and a second opening, the first opening for capturing exhaust air from the domestic cooking appliance and the second opening for permitting secondary air to exit an interior of the housing to form an air curtain that enhances a capture ability of the domestic ventilation appliance to capture the exhaust air, and a dual direction flow blower/fan configured both to convey the exhaust air through the housing from the first opening in a first direction and to convey the secondary air through the housing to the second opening in a second direction, the second direction being opposite the first direction.

Abstract: Antennas used aboard aircraft to communicate with satellites or ground stations may have complex antenna patterns, which may vary as the aircraft moves throughout a given coverage area. Techniques are disclosed for dynamically adjusting the instantaneous power fed to an antenna system to ensure that the antenna transmits at the regulatory or coordinated effective isotropic radiated power (EIRP) spectral limit. The antenna may transmit, in accordance with aircraft location and attitude, steerable beam patterns at different scan and skew angle combinations, causing variations in antenna gain and fluctuations in the transmitted EIRP. Using on-board navigational data, an antenna gain and ESD limit may be calculated for a particular scan and skew angle, which may be used to adjust power fed to the antenna such that the antenna transmits substantially at maximum allowable EIRP as the steerable beam pattern is adjusted.

Abstract: A radome having localized areas of reduced radio signal attenuation includes a body having a first portion and a second portion. The first portion has a reduced radio signal attenuation property in a transmit band and a second portion has a reduced radio signal attenuation property in a reception band.

Abstract: A method and system facilitate communication between a constellation of satellites and a mobile platform-mounted mobile communicator. The method and system may include the use of a first antenna suited for operation using a first frequency band in a first geographic region and a second antenna suited for operation using either the first or a second frequency band in a second geographic region. The method and system may use a controller to determine which antenna to activate based on one or more of a geographic indicator or a signal indicator. The system used by the method to facilitate the communication may have one or more enclosures over the antennas and controller for mounting to a mobile platform.

Abstract: A cooktop ventilation appliance or system provides ventilation of a domestic cooking appliance, and includes a complex curve interior flow surface in the housing, the complex curve interior flow surface partitioning the interior of the housing for separately conveying secondary air and exhaust air. A first side of the complex curve interior flow surface configured to guide and smooth a flow of the secondary air from an opening for receiving secondary air into the interior of the housing to an opening for permitting the secondary air to exit the housing to form an air curtain that enhances a capture ability of the domestic ventilation appliance.

Abstract: A flow washer assembly includes a housing with a channel for fluid flow, a seat positioned in the channel and including an upstream surface, and a washer press fit in the channel and engaging the upstream surface of the seat. The washer may be provided with a central opening that is sized according to predefined flow characteristics. An outside diameter of the washer at least adjacent an upstream end may be greater than an inside diameter of the channel such that the washer assumes a flexed orientation when press fit into the channel. Since the washer is pre-deflected, it will deflect further as inlet fluid pressure increases, effectively keeping the fluid flow rate relatively constant. The “pre-flexing” of the washer eliminates a spike in flow rate that occurs with conventional flow washer assemblies.
