Provided is a bench top organizer including a substantially rectangular rear panel, connected at opposite edges to two side panels to form a framework. One of the stereo signals is subtracted from the other signal with the aid of a subtraction module to obtain a single subtraction signal in which the correlated and in-phase components of the stereo signals have been removed. Instead of relying upon rotational energy, the present invention contemplates the use of a linear oscillator to produce the vibrations, and preferably utilizes at least one electromagnet to control the frequency and amplitude of a compacting vibration. The method includes, for each pixel in the third plurality of pixels, normalizing the pixel’s value as a function of the pixel values of at least six other pixels in the third plurality of pixels. The signal is generated by means of the oscillator and can be picked up on an output of the oscillator. In particular, the compounds of formula I are inhibitors of the human immunodeficiency virus reverse transcriptase enzyme which is involved in viral replication.
