摘要:
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.

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.

摘要:
An oscillometric blood pressure measuring device (200) is disclosed for determining systolic, mean and diastolic blood pressures. The device (200) includes a cuff (202) adapted to be continuously deflated during a measuring cycle. Analog signals representative of pulsatile changes in cuff pressure are utilized to generate signals representative of pulse characteristics, including peak amplitude and pulse integral characteristics. Difference signals are then generated for the pulses, representative of the difference between peak amplitudes and pulse integrals, and a determination is made as to the systolic and diastolic blood pressure based on these difference signals and static cuff pressures.
