  • Patent number: 5659308
    Abstract: Scan code generation for portable personal computers (PCs) using a matrix keyboard operates to produce keyboard output scan codes corresponding to IBM.RTM. compatible PC/AT scan codes. Key numbers are assigned to one or the other of two classes (simple and complex). Two classes of scan code translation tables (simple and complex) are stored in memory, either ROM or internal RAM memory. Whenever a simple key is operated, the simple table is accessed. The complex scan code table is addressed, in accordance with a set of seven edit rules, utilized in conjunction with the state of operation of multiple keys on the keyboard, to determine the appropriate translation. All of the logic needed to generate the necessary scan codes is collapsed into a structured table-driven mechanism.

  • Patent number: 5642104
    Abstract: An automatic lighting controller applies a turn-off control signal to a gate controlled power switch for switching OFF lighting when a timer circuit determines that motion activity above a threshold level has not occurred within the controlled area during a prescribed interval. A counter produces a grace period count signal and a reset count signal, with the grace period count signal occurring within a predetermined sub-interval, for example, one count cycle prior to the reset count signal. The grace period count cycle (N-1) interval is adjustable, for example, from about 0.6 second (for test purposes) to about 14 seconds. The grace period count signal enables an audio transducer which provides an audible alert that the lights are about to be switched OFF automatically. A person in the controlled area can override the impending automatic shutoff simply by initiating some motion activity during the grace period.

  • Patent number: 5642520
    Abstract: A method and apparatus for recognizing the topic structure of language. Language data is divided into simple sentences and a prominent noun portion (PNP) extracted from each. The simple sentences are divided into blocks of data dealing with a single subject. A starting point of at least one topic is detected and a topic introducing region of each topic is determined from block information and language data characteristics. A PNP satisfying a predetermined condition is chosen from the PNPs in each determined topic intro. region as the topic portion (TP) of the topic in the topic intro. region. A topic level indicating a depth of nesting of each topic and a topic scope indicating a region over which the topic continues is determined from the TP and sentences before and after the TP. Sub-topic intro. regions in the remaining area where no topic intro. regions are recognized are determined from block information and language data characteristics.
