Abstract: An image-capture-scope indication device for an image-capture apparatus. The image-capture-scope indication device includes: a light source, fixed on a surface of the image-capture apparatus on which a lens of the image-capture apparatus is provided; a light ray selection member, which is provided in front of the light source and has a light transmission portion; and a drive member. The drive member is configured for moving the light ray selection member so that a scope surrounded by light rays emitted from the light source and passing through the light transmission portion of the light ray selection member is provided that is consistent with an image-capture-scope of the image-capture apparatus.

Abstract: A system for sharing a USB Key by multiple virtual machines located at different hosts including at least two virtual machine managers, each virtual machine manager including a virtual machine transceiver module which is configured to receive a request for accessing a USB Key from a virtual machine within its host; a storage module which is configured to store an association relationship between a USB Key and the virtual machine authenticated by the USB Key; a verification module which is configured to, in response to judging that the virtual machine of the received request can access the USB Key, transmit the request for accessing the USB Key to a USB Key transceiver module of a virtual machine manager of the host where the USB Key is located; and a USB Key transceiver module which is configured to receive a request for accessing a USB Key, and to transmit an access request to a connected USB Key.
