Abstract: A multi-editing mode LOGIC BLOCK object editor is disclosed for creating and modifying LOGIC BLOCK objects that are incorporated into control strategies for process control systems (both distributed and discrete). The editor includes an RPN text editing mode wherein logic incorporated into a LOGIC BLOCK is represented by a list of text instructions. The editor also includes a graphical function block diagram editing mode wherein LOGIC BLOCK logic is defined via instruction shapes dragged/dropped from a pallet and connected via GUI line connection actions by a user. The editor supports automated transitioning between the text and graphics modes wherein conversion of text-to-graphics and graphics-to-text is performed without user intervention. Furthermore, synchronization procedures are performed when LOGIC BLOCK objects are opened in the editor and when transitioning between editing modes to track and/or maintain synchronous status between graphical and text representations of LOGIC BLOCK logic.

Abstract: A method and apparatus for ultrasonic frequency expansion is characterized by expanding audiometric frequencies before translation into the ultrasonic range. The audiometric signals are first expanded in time by a factor of 1/.beta. where .beta.<1 while generally maintaining the frequency content of the audiometric signals. Next the frequency of the signals is expanded by a factor 1/.beta. while compressing the time scale to that of the original signal. The frequency expanded signal is processed via a single-sideband upconverter to translate the frequency expanded signal into a single sideband signal in the ultrasonic range.

Abstract: A direction finding method and apparatus for a radio signal source, modulated by a digital information signal and existing in a heavy interference environment, is based on cyclic crosscorrelation. The direction finding technique exploits the second order periodicity of a transmitted signal having digital modulation, whereby the technique is immune to narrow-band interference. Radio frequency signals are received by two spaced antennas, and the signal of interest can be considered as a cyclostationary process. The signal time of arrival difference between the two antennas is determined using a cyclic crosscorrelation method. This is implemented by sending the electrical signals, developed by the antennas, through a variable delay device, then to a balanced mixer. The composite signal from the mixer is sent to a band-pass filter whose center frequency is equal to the baud rate of the signal of interest.
