Abstract: A modulation method and apparatus is provided which can coexist with conventional Manchester (Ethernet) coding schemes and which can be transmitted and received over twisted pair cabling. The method according to the invention is a three-level D.C.-free code without bipolar violations wherein intersymbol interference is sufficiently controllable that the received signal can be detected as a two-level code. The code has a different power spectrum than Manchester coding for the same baud rate. The modulation method is a modified frequency modulation (Miller) code comprising three levels wherein each of the transitions is of a limited duration and the transition returns to zero d.c. after a predetermined pulse duration. The modulation method may be termed pulsed modified frequency modulation or pulsed Miller encoding. The signal so modulated is intended to be transmitted over twisted pair cabling of limited bandwidth such that the cabling serves as a low-pass filter. The pulsed modified frequency modulation encoding method according to the invention produces a fundamental at a frequency which is about half of the fundamental of a Manchester coding scheme at the same bit rate.

Abstract: An image information code processing system in this invention compresses and encodes a 2-valued image information in a facsimile, etc. For example, an image is expressed by a set of component patterns using bit patterns of divided 4 × 4 bits rectangular blocks, and a codeword train of matched codewords of the component patterns are determined as a block code. In this system, using a four times expanded block process, the one block code of the expanded block is determined and the system expands to determine a partial pattern of three other blocks. A division mark located between the codewords of a codeword train can be abbreviated where a special condition exists between adjacent codewords. Further shortening can be obtained by coding wherein a prediction pattern is obtained and only a portion in which a real pattern is different from the prediction pattern is encoded. As a result, the 2-valued image information is compressed and the 2-valued image information can be transmitted and processed with a higher efficiency.

Abstract: An apparatus and method for debugging a forward-­chaining (rule-based) expert system are disclosed. A single STEP command controls the expert system and automatically presents prefire and postfire displays for observing the system's performance. The debugger alter­nates between prefire and postfire states. In the prefire state, before the selected rule is fired, the conflict set of rules eligible to be fired, the selected rule to be fired, and the data for that rule are display­ed in separate windows. Entry of the STEP command fires the rule and changes the debugger's state to postfire. In the postfire state, the just-fired rule and data updated thereby are displayed. Entry of the STEP command in the postfire state changes the state to prefire and automatically presents the prefire display for the next selected rule.
