Abstract: A method of controlling access to an automated media library receives a request or access to the library from an individual having an identity. Access may include importing media to the library, exporting media from the library, and opening a locked door to a cabinet containing the library.

Abstract: A method and system for utilizing the heat dissipated by quiescent IC leakage currents to control the start-up temperature of components. A temperature control sub-system utilizes a thermal sensor to sense the junction temperature of the component. When the temperature is below an operating threshold, the control sub-system applies power to the component, and the component is self-heated due to the quiescent leakage current inherent to the component. This quiescent self-heating property serves as a source of pre-heat to elevate the temperature of the component, until the temperature, as indicated by the thermal sensor, rises above the minimum specified operating temperature of the component. The system may then be reliably initialized by applying full system power, and triggering a hardware reset or defined initialization sequence/procedure. Once the component(s) is operational, self-heating continues to maintain the component's temperature above the minimum operating threshold.
