Abstract

Systems, devices, and methods are described that facilitate the transmission of image data collected by a sensor within a gimbal assembly. A gimbal assembly includes one or more sensors positioned within the gimbal assembly. The one or more sensors collect data. The gimbal assembly is controllable to aim the one or more sensors. The gimbal assembly further includes a communications module within the gimbal assembly. The communications module transmits at least one directional optical signal to communicate data collected by the sensor. At least one transducer is positioned to receive the at least one directional electromagnetic signal.

Claims

1. A system, comprising:

a gimbal assembly;

a sensor carried by the gimbal assembly, wherein the sensor collects data and wherein the gimbal assembly is controllable to aim the sensor, wherein the gimbal assembly has a range of motion for the sensor to collect the data;

a biological sensor;

a radiological sensor; and

a nuclear sensor.

7. The system of claim 1, wherein the at least one directional electromagnetic signal is an optical signal.

8. The system of claim 1, wherein the at least one directional electromagnetic signal is at least one of a narrow-beam electromagnetic signal or a broad-beam electromagnetic signal.

9. The system of claim 1, further comprising:

an operations module that processes data collected by the sensor and generates at least one signal to be transmitted by the communications module.

10. The system of claim 1, further comprising:

a second communications module positioned external to the gimbal assembly, wherein the second communications module transmits at least one second directional electromagnetic signal to the gimbal assembly.

11. The system of claim 10, wherein the at least one second directional electromagnetic signal includes at least one indication of control information for controlling the gimbal assembly.

12. The system of claim 10, wherein the at least one second electromagnetic signal includes energy, and wherein the gimbal assembly is operative to convert received energy into power.
