  • Patent number: 10135113
    Abstract: Techniques and mechanisms for enabling the positioning of a communication terminal in or on a vehicle, building or other structure. In an embodiment, the communication terminal includes an electronically steerable antenna which is disposed in a housing. A plurality of support legs, coupled to the housing, are each configured to rotate about a respective first axis, and to further rotate about a respective second axis. For a given support leg, an orientation of the respective second axis varies with rotation of that support leg about the respective first axis. Two such support legs are mechanically coupled to one another with respect to their respective first axis rotations or with respect to their respective second axis rotations. In another embodiment, the communication terminal is operable by a user to selectively enable or disable first axis rotation and/or second axis rotation of a given support leg.

  • Patent number: 10116893
    Abstract: A communication device, having an antenna, determines a direction substantially in a direction to an intended transceiver. A desired direction that is different from the direction to the intended transceiver, and an anticipated direction that is offset from the desired direction, are determined. Based on the desired direction, parameters of expected energy values corresponding to a multiple pre-defined antenna directions of the antenna around the desired direction are determined. The communication device receives, using the antenna, multiple measured energy values corresponding to multiple antenna directions of the antenna around the anticipated direction. A directional offset is calculated using the multiple expected energy parameters and the multiple measured energy values. An updated anticipated direction is generated by updating the anticipated direction using the calculated directional offset.

  • Patent number: 9912402
    Abstract: A direct broadcast satellite (DBS) reception assembly may receive a desired satellite signal and process the desired satellite signal for output to a gateway. The DBS assembly may also receive one or more undesired satellite signals and determine a performance metric of the one or more undesired satellite signals. The elevation angle of the assembly and/or the azimuth angle of the assembly may be adjusted based on the performance metric(s) of the undesired satellite signal(s). The adjusting of the elevation angle and/or the azimuth angle may comprise electronically steering a directivity of a receive radiation pattern of the DBS reception assembly and/or mechanically steering one or more components of the assembly via motors, servos, actuators, MEMS, and/or the like. The performance metric may be received signal strength of the undesired signals, received signal strength of the desired signal, SNR of the desired signal, and/or SNR of the undesired signals.

  • Patent number: 9699517
    Abstract: The satellite television antenna device scans the sky and locks onto a first satellite candidate by measuring microwave radiation. The antenna acquires identification (ID) of a first satellite candidate from a set top box (STB), if possible. Then, the antenna moves to a second satellite candidate and acquires the corresponding ID from the STB, if possible. Antenna dish orientation information is stored in memory for at least all satellites that were identified as corresponding to a user's television programming package. The antenna can switch directly between two or more stored dish positions in response to the user changing channels on the STB. The antenna can be powered solely by the STB. A two-way communication conduit can be established between the STB and the antenna via a single cable. The communications conduit can also be used to transmit power to the antenna.
