Abstract: A security device restricting access to various machines, places or data, using a security device that is kept in close proximity to a portion of the body of a person and is activated by an activation station to provide access to those machines, places or data to that person only when that person is confirmed to be an authorized person, and which is automatically deactivated when it ceases to be in close proximity to that person's body.

Abstract: A security device restricting access to various machines, places or data, using a security device that is kept in close proximity to a portion of the body of a person and is activated to provide access to those machines, places or data to that person only when that person is confirmed to be a designated person, and which is automatically deactivated when it ceases to be in close proximity to that person's body.

Abstract: A method for communicating between a camera and a computer includes determining whether it is possible to transmit data at a requested resolution and a requested frame rate. If not, the data is transmitted at an adjusted reduced resolution (a reduced resolution, for example).

Abstract: An intelligent power strip circuit for providing automatic computer system power down features and for providing automatic restoration of power for the computer system. The intelligent power strip circuit may be used by conventional computer systems that do not have internal power management features to retrofit them to provide power conservation modes. The circuit is responsive to an incoming phone call and will provide automatic power on and system initialization to enable the computer system to respond to a call. The circuit is responsive to the keyboard, mouse, and other user interface devices (for automatic power up and conditional timed power off) because these devices are routed through the external circuit to the computer system. Peripherals and the CPU chassis of the computer system receive their AC power via the circuit and therefore may be automatically powered down under control of the CPU when appropriate.
