Rotatable wireless electrical coupler
First Claim
1. A rotatable wireless electrical coupler having a first rotatable section that is rotatable relative to a second section, and designed to provide for the wireless transfer therethrough of electrical power and data signals between the first rotatable section and the second section, comprising:
- a rotatable transformer, including a first rotatable winding section and a second winding section, which winding sections rotate relative to one another, for transferring electrical power therethrough;
a rotatable electrical capacitor, including a first rotatable capacitor electrode and a second capacitor electrode, which capacitor electrodes rotate relative to one another, for transferring analog or digital data signals therethrough.

Abstract
A rotatable wireless electrical coupler is disclosed that presents a wireless alternative to mechanical slip rings, such as are used in rotatable mechanical assemblies such as dome cameras. The rotatable wireless electrical coupler is designed to provide for the wireless transfer therethrough of electrical power, video and data signals. A rotatable multi-function transformer of the electrical coupler is designed primarily for the transfer of electrical power therethrough, and can also be used for the transfer of data signals. A rotatable electrical capacitor of the electrical coupler is designed primarily for the transfer of video data signals therethrough, and can also be used for the transfer of control and feedback data signals. In a dome camera, the rotatable wireless electrical coupler transfers power and data signals to and from a rotatable platform/section on which is mounted a video camera, pan and tilt motors and other associated electrical components.
