  • Publication number: 20190268254
    Abstract: A load-controlling interfacing device obtains and processes event data, for example, from a touch-screen user interface and/or other devices, and that processes rules based on the event data to control an electrical load, such as a light fixture. During operation, when the interfacing device obtains event data, the interfacing device selects a rule to process based on the event data from the touch-screen user interface. If the interfacing device determines that the rule's condition is satisfied, the interfacing device can process the rule's action description to perform a corresponding action for controlling power to the electrical load.

  • Publication number: 20190215147
    Abstract: Systems and methods are presented that offer significant improvements in the performance of time division duplex (TDD) systems by utilizing an adaptive synchronous protocol. Conventional TDD systems are limited because data is transmitted during discreet and limited intervals of time, and because TDD transceivers may not simultaneously transmit and receive for reasons of insufficiently separated frequencies and limited receiver selectivity. Typically, TDD systems have significant latency due to the time to change from transmission to reception and the propagation delay time. By synchronizing the master nodes and the one or more remotes and by scheduling the traffic loads between these nodes, remote nodes may begin transmitting before the master node is finished with its transmission, and vice versa. This method reduces latency and improves the frame efficiency. Further, the frame efficiency may improve as the distance from the master node to the remote node increases.

  • Patent number: 10312598
    Abstract: Devices and systems, and methods of using them, for point-to-point transmission/communication of high bandwidth signals. Radio devices and systems may include a pair of reflectors (e.g., parabolic reflectors) that are adjacent to each other and configured so that one of the reflectors is dedicated for sending/transmitting information, and the adjacent reflector is dedicated for receiving information. Both reflectors may be in a fixed configuration relative to each other so that they are aligned to send/receive in parallel. In many variations the two reflectors are formed of a single housing, so that the parallel alignment is fixed, and reflectors cannot lose alignment. The device/systems may be configured to allow switching between duplexing modes. These devices/systems may be configured as wide bandwidth zero intermediate frequency radios including alignment modules for automatic alignment of in-phase and quadrature components of transmitted signals.

  • Publication number: 20190132014
    Abstract: Apparatuses and methods for simultaneously operating as a wireless radio and monitoring the local frequency spectrum. For example, described herein are wireless radio devices that use a secondary receiver to monitor frequencies within the operating band and prevent or avoid interferers, including in particular half-IF interferers. The systems, devices, and methods described herein may adjust the intermediate frequency in a superheterodyne receiver to select an intermediate frequency that minimizes interference. In particular, described herein are apparatuses and methods that use a second receiver which is independent of the first receiver and may be connected to the same receiving antenna to monitor the geographically local frequency spectrum and may detect spurious interferers, allowing the primary receiver to adjust the intermediate frequency and avoid spurious interferes.
