Patent number: 11894613Abstract: Vehicles with adjustable metamaterial systems, integrated on the outside or inside of their non-conductive fuselage, have the ability to control their radar cross section dynamically for the purposes of evading detection or spoofing their size by looking larger or more numerous. The frequency response of a metamaterial system can be obtained by combining the RF properties of the individual metamaterial layers that comprise it. A first metamaterial layer that can controllably switch between transmissive and reflection in a relevant frequency band and a second absorptive layer results in a controllable radar cross-section with the ability of controlling the amplitude of the reflected radar pulse. The first layer can be modulated with a repetitive waveform to change the phase of a reflected wave that results in a doppler shift in frequency. The frequency of the modulation can result in a change in range, velocity, or combinations of both.Type: GrantFiled: March 28, 2023Date of Patent: February 6, 2024Assignee: Notch, Inc.Inventor: Shahriar Khushrushahi

Publication number: 20220187922Abstract: The present disclosure provides touch communication devices that can convey touch information to a human user and/or receive touch information from the human user. As one example, a touch communication device can include a plurality of tactile units. The touch communication device can individually control each of the tactile units to apply a respective pressure to a surface adjacent to such tactile unit. For example, the touch communication device can control the plurality of tactile units to convey a touch communication to a human user that has the touch communication device adjacent to a portion of his body. As another example, the touch communication device is configured to determine a counter-pressure applied to each tactile unit by the surface adjacent to such tactile unit. The touch communication device can generate information descriptive of a touch communication performed by the human user on the touch communication device.Type: ApplicationFiled: March 7, 2022Publication date: June 16, 2022Inventors: Kelly Elizabeth Dobson, Rafeed A. Chaudhury, Nicolai Munk Petersen, Steve Albert Oh, Demetrious Mark Harrington, Ara Knaian, Shahriar Khushrushahi, Elena Koukina, Rachel Chaney, Veton Saliu, Yvan Stephane Pearson Lecours

Patent number: 10833402Abstract: A reconfigurable antenna system includes an antenna array; a set of metamaterial panels configured to surround the antenna array; a control unit, coupled to each of the metamaterial panels, for selectively addressing each of the metamaterial panels to control separately at least one property of each of the metamaterial panels; and a receiver coupled to the antenna array and to the control unit. The control unit is configured to monitor signal reception by the antenna array via the receiver and to establish a set of configurations of the metamaterial panels to produce a pattern of reception according to a set of prespecified criteria that include a set of azimuthal and elevational ranges characterizing the configurations. Optionally, the system further includes a transmitter coupled to the antenna array and to the control unit.Type: GrantFiled: February 15, 2019Date of Patent: November 10, 2020Assignee: Notch, Inc.Inventors: Shahriar Khushrushahi, Wardah Inam

Publication number: 20190389598Abstract: Embodiments of systems, devices, and methods are described that relate to module structures for use in forming a cabin interior of an aircraft. Many embodiments relate to a support structure including a lattice configurable to provide a standardizable frame for connection to the interior of the aircraft and to provide a space within the frame in which module fixtures can be positioned and secured to the frame. Embodiments of the support structure can include a floor with a number of structures and devices that can be used to provide support for the module and secure the module to the floor of the aircraft fuselage. Embodiments of transport systems for the modules are also described and such can be integrated with the floor of the module such that the modules transport mechanism, or a significant portion thereof, is contained within the module itself.Type: ApplicationFiled: September 4, 2019Publication date: December 26, 2019Inventors: Jason Lim Chua, Martin Sieben, Angelica Cardona, Guy M.
