Abstract: Abstract of the Disclosure A condition responsive control device is disclosed for affecting operation of a choke control system in response to variable ambient and system temperatures, as well as the  use of such a device in a system in which it is desired to adjust an operating parameter of the system in response to such tempera-tures.  The device includes an ambient temperature sensing switch which remains de-energized in response to ambient temperatures below a first preselected temperature level and is energized in response to temperatures in excess of this level so as to transmit an electrical signal in response to energization. The device also includes a system temperature sensing switch which remains unactuated in response to system temperatures below a second preselected temperature level and is actuated in response to temperatures above this level so as to effect an operating parameter of the system.  A self-regulating heating element is thermally coupled to the system temperature sensing switch and is adapted to generate heat at a substan-tially constant temperature level in response to electrical energization thereof.  The heating element is electrically coupled to the ambient temperature sensing switch and is energized in response to the electrical signal to effect accelerated heating of the system temperature sensing switch to said second preselected temperature level.

Abstract: DIGITAL REFERENCE MATRIX FOR WORD VERIFICATION          Abstract:   A digital reference matrix apparatus is disclosed for ver-ifying input alpha words from a keyboard, character recognition machine, or voice analyzer as valid linguistic expressions.  The organization of the digital reference matrix is based upon the character transfer function of the input apparatus.  The digital reference matrix contains a vector representation for each dic-tionary word in the form of a calculated vector magnitude and unique vector angle.  The set of magnitudes and angles is stored in the digital reference matrix using a form of run length cod-ing by storing a single magnitude pointer followed by the chain of unique angles for words having the same magnitude.  The vec-tor magnitude so calculated constitutes the address data for accessing the digital reference matrix.  When an input word is received for verification, the word's magnitude and angle att-ributes are calculated and the digital reference matrix is ac-cessed at the magnitude of the input word and the corresponding angles are searched for a match.  An output signal is generated indicating whether or not the input word is valid.  The organ-ization of the digital reference matrix minimizes the size of the array needed for accurate word verification representation through the use of the combination of digital angle represent-ation and run length compaction of the magnitude/angle verifica-tion syntax.
