  • Patent number: 7215357
    Abstract: A line blanker system for converting a stereoscopic image into a line-blanked stereoscopic image suitable for stereoscopic viewing on a standard non-interleaved display device is provided. The system includes a method for controlling the line blanker. According to the invention, one can enable and disable the line blanker, identify the first line of the image being processed and determine whether the first line is for viewing by the left eye or the right eye of a viewer. In addition, the invention includes a line doubler. The line doubler provides enhanced brightness and resolution by replacing the blanked line with a double of the line immediately adjacent to the blanked line.

  • Patent number: 6456432
    Abstract: The present invention relates to a system and method of viewing pairs of perspective images of 3-D objects (i.e. stereoscopic image pairs) displayed from a CRT display surface in a time-multiplexed or field-sequential manner, and more particularly to a universal method of generating control signals for synchronously changing the optical state of liquid crystal (LC) shutter panels through which the time-multiplexed perspective. images can be sequentially viewed in a substantially flicker-free manner by the left and right eyes of a human viewer, independent of whether the images are displayed on NTSC, PAL, VGA or SVGA styled CRT display devices.

  • Publication number: 20020026321
    Abstract: An improved system and method of fairly and securely enabling timed-constrained competitions over the Internet among millions of competitors while compensating for the variable network communication latencies experienced by client machines used by the competitors. The system employs globally time-synchronized Internet information servers and client machines in order to synchronize the initial display of each invitation to respond (e.g. stock price to buy or sell, query to answer, or problem to solve) on a client machine so each competitor can respond to the invitation at substantially the same time, regardless of his or her location on the planet, or the type of Internet-connection used by his or her client machine. Also, by using globally time-synchronized client machines, each competitor's response is securely time and space stamped at the client machine to ensure that competitor responses are resolved within microsecond accuracy.

  • Patent number: 5657584
    Abstract: A joint mechanism having a movement between relative members about a center of rotation located at a point where a first line extends from one of the members intersects a second line extending from the opposite member is disclosed. Multiple joint mechanisms may be aligned together along with common lines being the axis of rotation of each joint mechanism to provide a concentric spherical joint mechanism. Concentric spherical joint mechanism may be used to assemble truss frame structures.
