An apparatus may include a device and an image projection system configured to form an image on a surface viewable by a user. The image projection circuit may be configured to receive signals from the device, generate a pattern representative of data, process the pattern into a mirror image of the image, and project the mirror image from the device. The image projection system may include an electro optic system for generating the pattern, and an optics system for projecting the mirror image onto the surface. A method for projecting data may include providing the device with the image, and providing the image to the surface with the image projection system. The method may also include manipulating the device and/or a body part to locate and focus the image, sensing an orientation of the device, and orienting the image based, at least in part, on the sensing step.

A portable phone includes a handset and a data projection system configured to form a visual image of data, such as caller waiting ID data, on a viewing surface viewable by a user during a two way conversation. The handset also includes a speaker, a microphone, conventional phone circuitry and a keyboard. The data projection system is configured to receive signals from the phone circuitry, to generate a pattern representative of the data, to process the pattern into a mirror image of the visual image, and to project the mirror image from a bottom end surface of the handset. The projection system includes an electro optic system for generating the pattern, and an optics system for projecting the mirror image onto the viewing surface. A method for projecting data in a portable phone includes the steps of: providing the handset with the data projection system, conducting a two way conversation with the handset held against the head of the user, and forming the visual image on the viewing surface during the two way conversation with the handset held against the head. The method can also include the steps of manipulating the handset and a body part to locate and focus the visual image, sensing an orientation of the handset during the two way conversation, and orienting the visual image as a function of the sensing step.

A memory device includes isolation devices located between-memory cells. A plurality of isolation lines connects the isolation devices to a positive voltage during normal operations but still keeps the isolation devices in the off state to provide isolation between the memory cells. A current control circuit is placed between the isolation lines and a power node for reducing a current flowing between the isolation lines and the power node in case a deflect occurs at any one of isolation devices.

A method for controlling a field emission display to reduce emission to grid during turn on and turn off is provided. A field emission display (FED) includes emitter sites formed on a baseplate; a grid for controlling electron emission from the emitter sites; a display screen for collecting electrons to form an image and a power supply. In order to reduce emission to grid during turn on, the display screen is enabled by the power supply prior to enabling of the emitter sites. An anode-baseplate voltage differential is thus established prior to electron emission. For turn on, the method includes varying the capacitances of the control circuits for the display screen and grid such that a time constant (RC) for the grid is larger than a time constant (RC) for the display screen. Alternately the method of the invention can be implemented during turn on using software, using time delay circuit components, or using an emitter site control circuit to control electron flow to the emitter sites. During turn off, the electron emission and anode-baseplate voltage differential are eliminated while a path to ground is provided for the grid.
