Abstract: A system, apparatus, and method for passive dissipation of deconstructive harmonics during audio amplification and reproduction. An apparatus including an advantageous form and type of speaker baffle/enclosure is provided to isolate and/or dissipate deconstructive harmonics in an electrical loudspeaker system. A system for passive dissipation of deconstructive harmonics during audio amplification or reproduction from an audio speaker (the speaker having a front face and a rear) includes an encapsulation and isolation body within which the audio speaker is placeable, a mounting means upon the isolation body exterior, and a resiliently flexible baffle connected to the mounting means and extending rearwardly from the speaker. The baffle optionally is vented.

Abstract: An ergonomic worker support system. There is provided an apparatus for ergonomically supporting a user in any of a variety of positions while working. The stand apparatus includes a base from which an upright stem extends to an extension of stems fitting, which fitting in turn supports an upper torso support member. A stem extender piece may be provided between the upright stem and the upper torso support member. These various components are adjustable relative to one another to permit versatility in apparatus configuration. Convenience features are disclosed for reducing stress and supporting either the upper or lower portion of a user's body. The apparatus includes features that reduce stress, conserve energy, and facilitate increased work productivity of physically challenged persons as well able-bodied users. The ergonomic stand, in operational position, provides a sturdy, balanced, adjustable, and ergonomic platform for the support of the worker, appliances and tools.
