A projective MEMS device, including: a fixed supporting structure made at least in part of semiconductor material; and a number of projective modules. Each projective module includes an optical source, fixed to the fixed supporting structure, and a microelectromechanical actuator, which includes a mobile structure and varies the position of the mobile structure with respect to the fixed supporting structure. Each projective module further includes an initial optical fiber, which is mechanically coupled to the mobile structure and optically couples to the optical source according to the position of the mobile structure.

A device controller controls access to a device, such as a television, having a power input for receiving power and a data input for receiving control data. When in standby mode, the device controller disconnects the device from a power source, such as the AC mains of the building in which the device is situated. As a result, in standby mode only the device controller is powered, which uses much less power than prior art devices in standby mode. The device controller includes an input device structured to provide control data based on control instructions received from a user, a power switch coupled between a power source and the device power input, and a data coupler coupled to the device data input and structured to convert electrical data into non-electrical data and back to the electrical data for delivery to the device data input. The device controller also includes a controller structured to cause the data coupler to provide the control data to the device data input, decode the control data, and if the control data indicates that the user desires to turn on the device when in standby mode, then causes the power switch to deliver power from the power source to the device power input.

A cathode-ray tube video device connected to a power source and having a first normal operating state and at least a second operating state at reduced power (stand-by mode) includes a switching power supply and a circuit portion for demagnetizing the cathode-ray tube coupled to the power source through an electrically actuated switch. The switch is closed to demagnetize the cathode-ray tube during the first operating state of the device, and opened during the second operating state at reduced power of the device.
