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.

A global synchronization unit (GSU) for time and space (TS) stamping of input data elements. The GSU comprises a GPS Receiver and an associated antenna for receiving GPS signals from signal sources associated with a GPS system symbolically embedded within a global reference system, and processing received GPS signals so as to automatically produce time and space (TS) stamp data element representative of the time and space coordinates of the GSU with respect to said global reference system at each data sampling instant occurring within the GSU. The GSU further comprises a central processor, operably connected to the GPS Receiver, and also a data input port, operably connected to a data input device and the central processor, for receiving an input data element from the data input device, at each data sampling instant. During GSU operation, the central processor (i) connects the input data element received at the data input port at each data sampling instant, with the TS-stamp data element generated at the sampling instant so as to produce a TS-stamped input data element, and (ii) stores each TS-stamped input data element in memory. By virtue of the present invention, the GSU enables collection of TS-coordinate information aboard the GSU for storage and subsequent transmission to a host computing device, which may be connected to an information network. The GSU can be used in diverse user applications, in which TS-stamping operations are required.

An Internet-based method of and system for monitoring space-time coordinate information and biophysiological state information collected from an animate object moving along a course through the space-time continuum. The Internet-based system comprise a wireless GSU-enabled client network device affixed to the body of an animate object. The wireless device includes a global synchronization unit (GSU) for automatically generating time and space (TS) coordinate information corresponding to the time and space coordinate of the animate object with respect to a globally referenced coordinate system, as the animate object moves along a course through the space time continuum. The device also includes biophysiological state sensor affixed to the body of the animate object, for automatically sensing the biophysiological state of the animate object and generating biophysiological state information indicative of the sensed biophysiological state of the animate object along its course. The wireless device also includes a wireless date transmitter for transmitting the TS coordinate information and the biophysiological state information through free-space. A TS-stamping based tracking server receives the TS coordinate information and the biophysiological state information through in a wireless manner, and stores the same as the animate object moves along its course. An Internet information server serves Internet-based documents containing the collected TS coordinate and biophysiological state information. An Internet-enabled client system enables authorized persons to view the served Internet-based documents and monitor the collected TS coordinate and biophysiological state information, for various purposes.

An Internet-based system for enabling a time-constrained competition among a plurality of participants over the Internet. The Internet-based system comprises: a primary server having an embedded global positioning system (GPS) receiver; one or more web servers for providing information about the competition on the World Wide Web (WWW); a login server for enabling participants to log-in with the system prior to the competition; a competitor/participant database for storing information about each participant registered to participate in the competition; an invitation-to-respond/response database for storing invitations-to-responds (ITRs) (e.g. queries, problems, etc.) to be simultaneously displayed to participants at the competition, as well as the responses provided by each of the participants in response to the ITRs; one or more competition-promoting servers, each having an embedded GPS receiver, and conducting the competition process; and a plurality of GSU-enabled client machines. Each GSU-enabled client machine has an embedded Global Synchronization Unit (GSU). Each GSU-enabled client machine enables a registered participant to receive and display ITRs simultaneously with each and every other participant, and provide time and space (TS) stamped responses to the competition promoting servers. The competition promoting server fairly determines a winner amoung the participants independent of network latancies. All such components are interconnected with a globally-extensive network (e.g. the Internet) to enable the competition among the participants.

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.
