  • Method and apparatus for alphanumeric data entry using a keypad
    Patent number: 6847706
    Abstract: A keypad for entering letters includes an array of keys with each key being assigned to at least one letter of an alphabetical system based on the frequency of occurrence of the least one letter in a typical body of written work. Thealphabetical system comprises at least one most-frequently-occurring letter that is entered by activation of the same key twice and at least one less-frequently-occurring letter that is entered by activation of two different keys.
    Type: Grant

  • Apparatus and method identifying false timing paths in digital circuits
    Patent number: 5675728
    Abstract: A method for identifying false paths in a digital circuit. A list of paths corresponding to the digital circuit is either provided or generated. For each path, an AND gate is created. For each element in the path, the off-path signals of the monitor circuits corresponding to the elements of the path are coupled to the input of the AND gate. A plurality of different signals are input to the digital circuit in an attempt to generate a "1" at the output of the AND gate. A false timing path signal is generated for that path if the AND gate does not output a "1" within a pre-determined amount of time. This process is repeated for each path of the digital circuit to identify all false timing paths.
