Abstract: A positioning system, attachable to a vehicle for remote operation of the chain saw by a user sitting in the vehicle. A shock absorber indicator functions to tell the user when the weight on the limb is appropriate to engage the saw, and additionally cushions the drop when the saw cuts through the limb.

Abstract: Eyewear for enhanced hearing includes a first sound detector positioned on or adjacent a first lens of the eyewear, and a second sound detector positioned on or adjacent a second lens of the eyewear. A processing unit positioned on the eyewear is in communication with the first and second sound detectors. The processing unit utilizes software that includes instructions for determining a time differential between detection of a sound by the first sound detector and detection of the same sound by the second sound detector. Because the time differential is proportional to the angular displacement of the sound from directly in front of the eyewear or person wearing the eyewear, sound signals corresponding to detected sounds having an angular displacement less than a stored maximum angular displacement value can be preferentially enhanced and transmitted via a data transmission module to a hearing aid device.

Abstract: A transparent lens microphone comprises (a) a refractive eyeglass lens; (b) a sound sensitive coating on an outer surface of the refractive lens; and (c) electrical contacts connected to the sound sensitive coating so as to provide an electrical analog signal representative of an acoustic signal striking the outer surface of the transparent lens microphone.
