Abstract: A method and system designed to augment, rather than replace, the work habits of its users. These work habits include practices such as drawing on Post-it™ notes using a symbolic language. The system observes and understands the language used on the Post-it notes and the system assigns meaning simultaneously to objects in both the physical and virtual worlds. Since the data is preserved in physical form, the physical documents serve as a back-up in the case of electronic system failure. With the present invention users can rollout a primary paper document such as a map, register it, and place secondary physical documents on the map. The secondary physical documents can be moved from one place to another on the primary document. Once an object is augmented, users can modify the meaning represented by it, ask questions about that representation, view it in virtual reality, or give directions to it, all with speech and gestures.

Therefore, it is possible to provide a display control apparatus that is able to perform intermediate color display, with reduced manufacturing cost and reduced power consumption.

Abstract: The camera reads identification information of the user, which is contained in an identification card, through a card reading part. The camera connects automatically to a server designated in accordance with the read identification information through a communication interface. Then, the camera transmits and stores the data of recorded images to the designated server. The camera retrieves the image data stored in the server, and reproduces and displays the image on an image display at the back of the camera. A plurality of cameras in which the same user's identification information is set can be controlled altogether in the image-recording and reproduction by one camera. One camera in which the identification information of a plurality of user's is set can distribute the recorded image data to the servers of the users simultaneously.

Abstract: A display apparatus includes a scanning assembly that scans about two or more axes, typically in a raster pattern. A light source emits light toward the scanning assembly such that the scanning assembly simultaneously scans more than one of the beams. The light source is positioned such that its beam illuminates a discrete region of the image field. The image may be formed from a set of “tiles” where a single sweep of the scanning assembly scans a plurality of beams simultaneously. Various approaches to controlling the intensity of the light to compensate for variations in light source response or optical system response, or to balance the response of a tiles system are described. Among these approaches are scaling data in a buffer, active multiplication, or control of a D/A converter.

Accordingly, an impedance difference between the radio frequency electrode lines caused by a length difference of radio frequency supply lines is uniformly compensated, so that a maximum power of radio frequency signal can be applied to each radio frequency electrode line to provide a stable operation of the panel as well as to improve a picture quality.

Abstract: A hybrid-level charge recycling method for use in implementing low power LCD column drivers. By having external capacitors of the column driver drive the same column lines of the LCD, the need for a polarity reversing circuit is eliminated, and the time necessary for charge recycling, as well as the amount of power consumed, is reduced. As a result, the multi-level recycling operation in column driving IC is made more practical.

Abstract: The present invention is a portable electronic video display. The display is configured to be worn on the arm or wrist of a user, or stored in a pocket or backpack. The display is raised to eye level and the user looks through an eyepiece to view the video display. Control buttons are located on the display for generating point and click type commands. The display is meant to be used remotely from a computer. The computer could be worn or carried by the person or simply be free standing, some distance away. The computer is configured to convert video signal into a serial data stream and then transmit that stream via an RF signal. The display then receives that signal and converts it back into a video signal, displaying it on a miniature electronic video display. That image is them magnified through various optics to present a final image to the user. The point and click commands are separately transmitted back to the computer, where they are received and acted upon.

Abstract: In conventional liquid crystal display controllers such as for portable telephone sets, the display is reduced in the stand-by state but the liquid crystal display duty is not changed, i.e., even the common electrodes of the rows that are not producing display are scanned, and the consumption of electric power is not decreased to a sufficient degree in the stand-by state. A liquid crystal display controller (2) includes a drive duty selection register (34) capable of being rewritten by a microprocessor (1), and a drive bias selection register (32). When the display is changed from the whole display on a liquid crystal display panel (3) to a partial display on part of the rows only, the preset values of the drive duty selection register and of the drive bias selection register are changed, so that the display is selectively produced on a portion of the liquid crystal display panel at a low voltage with a low-duty drive.

With this circuit construction, there is substantially no electromagnetic noise generated and it is possible to maintain a terminal voltage of the LED substantially constant according to the diode characteristics of the LED even when voltage ripple appears in an output of the booster circuit due to the n/m voltage boost, by setting the switching frequency at high to absorb the ripple component on the side of the constant current circuit.

Abstract: A light modulator is comprised of two unit devices each using surface plasmon generated at the interface between thin metal films respectively formed on prisms and an electro-optical material, and a mirror. Both of the transmitted light due to absorption and re-radiation, and the reflected light arising from the unit devices are made into the outgoing light, the incident light on the next unit device, or the incident light on the mirror. Consequently, all light beams can be utilized as the final outgoing light beams with no loss of light. Further, the color of light can be spatially divided, and still further, it can also be temporally divided by changing the wavelength due to a voltage. As a result, the original light can be divided both temporally and spatially with almost no loss by combining two unit devices so configured as to re-radiate the absorbed light by surface plasmon using surface plasmon and a mirror, and thus utilizing both of the reflected light and the transmitted light.
