  • Publication number: 20240063344
    Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and a semi-transparent metallic layer deposited on an LED chip that can dim a light output of the LED chip are disclosed. The thickness of the semi-transparent metal layer can be adjusted based on the desired dimming level. In an embodiment, the metallic layer can be deposited on top of a passivation layer over the LED structure, so that the metallic layer is not electrically coupled to the LED. The metallic layer can additionally cover the mesa sidewalls of the LED structure. The metallic layer can be titanium, or platinum, or other suitable metals in other embodiments. In an embodiment, the metallic layer can be deposited on to the passivation layer, where a length of time the metallic layer is deposited, can be based on the amount of dimming desired.

  • Patent number: 11094848
    Abstract: Solid-state lighting devices including light-emitting diodes (LEDs) and more particularly LED chip structures are disclosed. LED chip structures are disclosed that include reduced bonding topography between active LED structures and carrier submounts. For certain LED chip structures, active LED structures are formed on a growth substrate and subsequently bonded to a carrier substrate. Bonding between active LED structures and carrier submounts is typically provided by metal bonding materials. By providing reduced bonding topography between active LED structures and carrier submounts, bonding strength of metal bonding materials may be improved. Electrical connection configurations for certain layers of active LED structures are disclosed that promote reduced bonding topography. Peripheral border configurations of carrier submounts are also disclosed with that promote reduced bonding topography along the peripheral borders.

  • Publication number: 20200350676
    Abstract: A method of assembling an antenna aperture from a plurality of antenna aperture segments is described. The method may include placing a first aperture segment relative to a second aperture segment to partially form the antenna aperture. Furthermore, an overlap of the first aperture segment overlaps a complementary underlap of the second aperture segment at a seam. The method may also include joining the overlap of the first aperture segment to the underlap of the second aperture segment to partially form the antenna aperture.

  • Patent number: 10535919
    Abstract: Techniques and mechanisms for providing a low-profile terminal for satellite communication. In an embodiment, a communication terminal includes a radome, an array of radio frequency (RF) elements and a foam layer disposed therebetween. The foam layer includes a first side and a second side opposite the first side, wherein the array of RF elements and the radome are coupled to the foam layer via the first side and the second side, respectively. The communication device provides contiguous structure between the radome and the array of RF elements. In another embodiment, the first side forms a machined surface which contributes to flatness of one or more antenna panels having the array of RF elements disposed therein or thereon.

  • Patent number: 7554527
    Abstract: There is described an apparatus which monitors the orientation of or the rotational movement of a substantially spherical body. The apparatus comprises a substantially spherical body with at least one resonant circuit fixed thereto. A transmit aerial generates an alternating magnetic field in the region of space including the spherical body which induces an electric signal in the or each resonant circuit, and a receive aerial receives an induced sense signal generated in response to said induced electric signal in the or each resonant circuit. The electromagnetic coupling between the transmit aerial and the receive aerial via the or each resonant circuit varies in accordance with the orientation of the spherical body so that the induced sense signal in the receive aerial varies in accordance with the orientation of the spherical body.
