摘要： A trainable transceiver may comprise an electro-optic element comprising a first substrate having an electrode coating on a surface; a second substrate generally parallel to and in a spaced-apart relationship with the first substrate and having an electrode coating on a surface; and a window in at least one of the first substrate and the second substrate from which the electrode coating has been at least partially removed. The trainable transceiver may also comprise a machine-readable optical image selectively visible through the window; a light source disposed in proximity to the machine-readable optical image; and a controller capable of controlling the light source. Upon receipt of an appropriate input, the controller causes the activation of the light source which, in turn, causes the machine-readable optical image to be visible through the electro-optic element.

摘要： The present invention provides a system for control and guidance of an unmanned aerial vehicle (UAV) using modulated laser light in radio frequency (RF) contested environments. The system enables the user to send light signal communications to the UAV from a handheld device. In one embodiment, where the handheld device is capable of being incorporated into a firearm fore-grip with built-in controls that allow for control of the UAV by a user in a shooting/aiming position. The UAV includes an optical array for detecting and receiving the light signal communications, as well as filtering systems for filtering out unnecessary image data for better control in different weather and time conditions, as well as an avoidance system to avoid objects and other UAVs when used in a swarm of UAVs.

摘要： A robust wireless communications network is deployed by retrofitting spatially distributed light sockets with integrated light/communicator modules. Each light/communicator module comprises an electric lamp and a communicator unit, the communicator unit having an RF transceiver, an antenna, and a Broadband processor for communicating with other nodes in the wireless communication network, using a suitable mesh network protocol. A power conversion unit is optionally provided in each integrated light/communicator module so that the individual components of the module may operate on the standard light socket power or selectably from other power sources.

摘要： Disclosed is a light intensity signal transmitting device based on a high-speed LED array. The light intensity signal transmitting device includes an LED array and a control board card; through a novel arrangement and driving mode, the LED array has a high-speed modulation characteristic and can transmit high-bit light intensity information at the switching speed of single-point LEDs; the control board card performs high-speed display by gating an I/O port of the LED array, and is used as a light intensity signal transmitting end to transmit a light signal. According to the light intensity signal transmitting device, on the premise that the switching rate of the LED array is ensured, multi-bit binary data transmission is realized, and the transmission rate is improved.
