Abstract: A computer security system and method comprises a security device (1) which incorporates a connection arrangement (12i) which is configured to be connected to a communication port of a computer (2). The security device (1) comprises a communication module (14) which is configured to communicate data between the security device (1) and a remote management device (5). The security device (1) further comprises a control unit (13) which is configured to control remote data communication between the communication port of the computer (2) and the remote management device (5) via the connection arrangement (12) and the communication module (14). The control unit (13) is configured to enable the remote data communication in response to an authorization signal received from the remote management device (5) and the control unit (13) is configured to disable the remote data communication when the control unit (13) is not authorized by a signal from the remote management device (5).

Abstract: An improved wafer holder design is described which has manufacturing and performance advantages over present state-of-the-art holders used in various wafer processing applications. The new wafer holder design incorporates a series of short radial grooves. The grooves extend from the base of a circular channel, which runs along the outside diameter of the substrate wafer recess, to a fixed radial location which varies based on wafer size and thickness. The grooves provide a slight overlap with the wafer to facilitate the free exchange of gases beneath the wafer necessary for wafer loading and unloading operations. The short length of the radial grooves make the wafer holder easier to manufacture and offer more robust performance compared to the present state-of-the-art holders.
