Abstract: A shaft voltage reduction structure is mounted on an electric machine having a bearing house and a rotor shaft rotatably connected together, and includes an electrically conductive main body, at least one electrically conductive bearing, and an electrically conductive shaft. The conductive main body is mounted to a bottom of the bearing house and includes a conductive shaft barrel projected from a center thereof. The conductive shaft barrel internally defines a shaft receiving hole, in which the conductive bearing is received. The conductive shaft includes a connecting end and a pivotal end connected to the rotor shaft and the shaft receiving hole, respectively. A shaft voltage across the rotor shaft of the electric machine is guided by the conductive shaft to release in a closed loop formed among the conductive main body, the conductive bearing and the bearing house, so as to reduce the shaft voltage of the electric machine.

Abstract: There is provided an image capturing apparatus able to be draped onto a stand. The apparatus includes an image capture module for capturing at least one image; and a flexible cable originating from the image capture module for connection of the image capture module to a host. The flexible cable may be for supporting the image capture module at a desired position when the image capturing apparatus is draped onto the stand. Advantageously, locating the image capture module at the desired position enables a user to look at a lens of the image capture module in a manner where a recipient of an image of the user views the user looking directly at the recipient during a video conference session. There are also provided methods for enabling a user to appear to be looking directly at a recipient of an image of the user during a video conferencing session.
