Abstract: The invention concerns an active electronically steerable antenna including: a planar or quasi-planar radiating array configured to transmit and/or receive radiofrequency or microwave signals, and a plurality of three-dimensional U-shaped modules, each arranged behind, and coupled to, a respective planar or quasi-planar radiating subarray of N radiating elements arranged in two rows or columns, each of N/2 radiating elements, N being an even integer. Each three-dimensional U-shaped module comprises: a respective base wall; two respective side walls that are orthogonally arranged with respect to the respective base wall so as to form therewith a respective three-dimensional U-shaped structure, and are arranged, each, behind a respective row or column of N/2 radiating elements of the respective planar or quasi-planar radiating subarray; and respective transmit and/or receive electronics distributed on said respective base and side walls and configured to implement N respective transmit and/or receive modules.

Abstract: A mobile sanitization system includes a movable trolley having an arm that is extendable between a first position in which the arm is in a collapsed state and a second position in which the arm is extended outwardly. The mobile sanitization system includes at least one ultraviolet light source coupled to the arm that is configured to illuminate to disinfect. The mobile sanitization system includes a source of liquid disinfectant and at least one nozzle fluidly coupled to the source of liquid disinfectant. The nozzle is coupled to at least one of the trolley and the arm, and the nozzle is configured to dispense the liquid disinfectant. The mobile sanitization system includes a spray wand removably coupled to the trolley and fluidly coupled to the source of liquid disinfectant. The spray wand is removable from the trolley to dispense the liquid disinfectant to disinfect a targeted area.

Abstract: A Multi-Beam on Receive Electronically Steerable Antenna comprising a Tx array comprising a phased array of Tx antenna elements and having a geometric aperture with one or more pairs of parallel opposite sides; and an Rx array comprising a phased array of Rx antenna elements and having a geometric aperture with one or more pairs of parallel opposite sides. One or more pairs of parallel opposite sides of the geometric aperture of the Tx array are inclined relative to one or more pairs of parallel opposite sides of the geometric aperture of the Rx array.

Abstract: A distributed bleed system temperature management scheme utilizes a distributed, closed loop temperature protection function. By allowing consumer systems to limit the consumer flow to meet a specified bleed system outlet temperature (which may be different for each consumer or group of consumers), each system can be penalized according to their level of importance. The closed loop approach allows optimization of the performance reduction instead of relying on conservative assumptions as is done with conventional systems. In some embodiments, each consumer system may have a different temperature limit at which the consumed flow is limited to maintain a given bleed system exit temperature. The temperature setpoints may be separated by a minimum temperature, based on sensor and controls tolerances, to ensure that the flow limiting functions do not interact with each other.

Abstract: A fuel tank inerting system uses two “half systems” for providing inerting gas for the fuel tanks. Each inerting system may be composed of a temperature control and air pressurization unit (TCPU) and an air separation unit (ASU). A cross-ship duct and valve allows using one TCPU (sized for about half capacity or more, but less than full system capacity) connected to two ASUs. The inerting system may provide for redundancy in the TCPU section.
