An information display device, after detecting the completion of charging of a battery, counts the number of times that display content of a nonvolatile display part is rewritten. Based on the number of times of rewriting processing, the information display device derives information on a remaining battery capacity of the battery. The information display device displays the derived information on the remaining battery capacity.

A three-dimensional sense adjusting unit displays three-dimensional images to a user. If a displayed reaches a limit of parallax, the user responds to the three-dimensional sense adjusting unit. According to acquired appropriate parallax information, a parallax control unit generates parallax images to realize the appropriate parallax in the subsequent stereo display. The control of parallaxes is realized by optimally setting camera parameters by going back to three-dimensional data. Functions to realize the appropriate parallax are made into and presented by a library.

The unit includes a first set of three modulated visible-light lasers co-aligned and adapted to provide a laser beam with selectable color and a first scanner unit providing both horizontal and vertical scanning of the laser beam across a portion of the curved reflector in directions so as to produce a reflection of the color laser beam through the pupil of the eye onto a portion of the retina large enough to encompass the fovea. The unit also includes a second set three modulated visible-light lasers plus an infrared laser, all lasers being co-aligned and adapted to provide a color and infrared peripheral view laser beam, and a second scanner unit providing both horizontal and vertical scanning of the visible light and infrared laser beams across a portion of the curved reflector in directions so as to produce a reflection of the scanned color and infrared laser beams through the pupil of the eye onto a portion of retina corresponding to a field of view of at least 30 degrees×30 degrees.

An active type of display panel arranged with light-emitting elements such as organic electroluminescent elements, capable of effecting correct tonal display even during a long-time use, a display device using the display panel and a method of driving the display panel. In each of pixel portions on the display panel, a driving element is activated according to a data signal, to supply a light-emitting element with a drive current in an amount corresponding to the data signal. The data signal is corrected such that the drive current becomes equal to a current corresponding to a light-emitting luminance represented by the data signal.

A method and system for sharing content between web clients. Specifically, a client computes and transmits its displayed content and web client state to one or more other web clients, which display the content. This enables the web clients to share the exact displayed content, even in the presence of dynamic modifications of the content local to the client.

An active type display panel comprises a plurality of pixel sections each having a series circuit constituted by a light emitting element and a drive element for supplying a drive current to the light emitting element, a pair of power supply lines which connect the series circuits of the pixel sections in parallel, and a plurality of measurement lines. Each of the pixel sections includes a switch element between a point connecting the light emitting element and the drive element, and one line of the measurement lines. A display device, in which the display panel is used, detects the voltage across the terminals of the light emitting element and controls the drive element such that the voltage across these terminals is a predetermined voltage.

The encoding method obtains a video stream including pictures and display information, the pictures being L-R containing images each having a display area split into two sub-areas, one storing a left-view image and the other storing a right-view image. The display information includes 2D display information and 3D display information, each of which including cropping information specifying an area in the display area as an area to be cropped, the area in the display area specified by the cropping information of the 3D display information is for 3D display, and the area in the display area specified by the cropping information of the 2D display information is for 2D display, and is one of the left-view image and the right-view image.

A system and method for managing graphics applications include the capability to receive graphics data from an unaware graphics application and convey the graphics data to at least one of a plurality of graphics pipes having different display directions. The system and method further include the capability to modify the graphics data to account for non-planar display of the graphics data.

A system and method for describing local area geo-reference features and landmarks in providing high resolution asset location information. Geo-image data is integrated to a mapping application and geo-reference data to add more detailed scale levels to the map. The geo-image data includes geo-images and its features to provide more detailed references to the asset and support the larger references of the geo-reference data. To describe a geo-reference landmark, an original landmark representation is selected with a center point and a radius. The asset location points located at the original landmark representation are compiled along with the asset location points generated by events occurring at the landmark to create a point set. The point set replaces the original landmark representation when a prescribed number of points is reached. The asset location points that are within a specified distance from any of the points in the point set are added to the point set to complete the landmark representation. The geo-image data and landmark representation data are combined to provide high resolution asset location information.

Detector signals in a pulse oximeter are analyzed to determine a quality of the signals in relation to desired information content or artifact content. The analysis involves performing a transform on a signal to obtain frequency related information and analyzing the frequency related information to obtain a value independent of a shape and waveform of a spectrum of the time-based signal. In one implementation, the analysis involves the relative amplitude or power measures of corresponding peaks in the red and infrared spectra. For example, the ratio of the amplitude of the fundamental peak in the red spectrum and the amplitude of the fundamental peak in the infrared spectrum may be tracked over time. In another implementation, the analysis involves consideration of the relative phase of the fundamental and harmonic components of a signal. In either case, signals including desired physiological information can be distinguished from artifact affected signals. Based on this analysis, signals can be validated or an appropriate processing algorithm can be selected.

An obstacle detecting unit detects whether an obstacle exists in an area surrounding a vehicle in the direction a camera installed on the vehicle is pointed. If the obstacle is determined to have a portion at a predetermined height above a road surface with which the vehicle may make initial contact when the vehicle moves toward the obstacle, a virtual projection surface is set to the height of the predicted contact portion and viewpoint conversion processing is performed so as to project pixels of an image captured by the camera onto the virtual projection plane. In this way, the height of the projection plane and the height of the predicted contact portion match each other and the distance between the predicted contact portion and the vehicle is accurately expressed on a bird's-eye view image resulting from the viewpoint conversion.

A surgical drill for use with a computer assisted surgery system. In a first embodiment, at least three localizing emitters are mounted on and integral with each side of the drill housing, the emitters on each side arranged such that they are visible to a localizing device when that side is facing the localizing device. The emitters on each side are spaced sufficiently apart from one another to provide accurate pose information. In a second embodiment, the emitters are mounted on both sides of a two-sided fin assembly attached to the housing.
