Abstract: A level discrimination circuit includes two offset compensation circuits. Each offset compensation circuit receives a differential pair of input signals, detects their peak values, and adds the peak value of each input signal to the other input signal, thereby generating an offset-compensated differential pair of output signals. The output signals of the first offset compensation circuit are used directly as the input signals of the second offset compensation circuit. The output signals of the second offset compensation circuit therefore have the correct duty cycle, and can be correctly discriminated by a comparator, even if the input signals to the first offset compensation circuit are burst signals in which each burst includes a large direct-current bias. This level discrimination circuit is suitable for receiving optical signals transmitted in bursts.

Abstract: A computer system includes a computer, operatively connected to a network, and having at least one memory with a plurality of messages and a message agent stored therein. The message agent generates a time score for each message based on how long visitors interact with the message. The message agent also generates a skip score for each message based on whether visitors skip the message. In response to a request to view one or more messages, the message agent creates a filtered set of messages by using a minimum time score and/or a maximum skip score to omit, from the requested messages, any messages having time scores and/or skip scores less or greater than the minimum time score and/or maximum skip score, respectively. The message agent then sends the filtered set of messages to the visitor for viewing. A visitor may set a minimum time score and/or maximum skip score according to preference.

The second IC chip also includes a sampling circuit coupled to receive the compare signal. With the sampling circuit, an output signal indicative of skew existing between the first and the second clocks can be asserted according to the compare signal.

Abstract: A composite liquid crystal panel includes a plurality of liquid crystal panels and a picture display surface. It cuts the border of each liquid crystal panel to a width of only one pixel, then bonding the panels together, installing the picture display surface on the liquid crystal panel, and distributing a portion of light from the normal pixels adjoining the border to the pixels corresponding to the border to resolve the gap problem. Light distribution is accomplished by using a pair of mirrors and a pair of reflecting surfaces to reflect the light of the pixels, so that light may be reflected above the pixels on the border and generate light. Then the pixels on the border and the pixels adjoining the border are redefined to form an image dot. Finally, through redistributing the light, the seams on the border may be completely eliminated.
