Abstract: An amplification device for use with a phone or other electronic device having a speaker. The amplification device typically includes an amplification structure having an input end and an output end, and an adapter located proximal to the input end and configured to engage a phone or other electronic device such that a speaker on the phone or other electronic device emanates sound into the input end, whereby the sound is amplified by the amplification structure.

Abstract: The present invention relates to a portable self-propelled transport device. In some embodiments, a drive system is provided that includes a hand-pumped tiller coupled to the front wheel of a three-wheel chair. Pumping of the lever provides propulsion to the device in the forward or reverse direction as determined by how the lever is pumped. In some embodiments, the tiller is collapsible to enable the operator to approach a table while sitting in the wheel chair. In some embodiments, the chair may be collapsed for easy storage of the device.

Abstract: A glass grinder or saw arrangement that includes a work surface that may tilt at an angle relative to the floor or surface on which the arrangement rests. Additionally, the arrangement also includes a pump for providing coolant to the grinder bit. The pump, in one aspect, is operably coupled to a motor for the glass grinder and recirculates water from an internal water tray to a diamond tool by means of tubing. The pump is powered by the motor and thus, turns off when the grinding head is turned off. Alternatively, a separate pump or a gravity water system, such as a tower that is in use with current grinders, may be provided in place of the motor-controlled pump. Adjustable feet may be used to adjust the tilt angle and/or a rotatable base portion may be rotated to obtain the tilt angle.
