Timer The TV Timer is a low-cost channel control designed for use in the hospital and hospitality industries, or any situation where access to specific television channels needs to be controlled. Existing solutions such as set-top decoder boxes or scramblers provide functionality but can be quite expensive. The TV Timer has an on-screen status display, is operated via a custom infrared remote control, is self-contained within the television, and best of all, only costs about $40 to build. The TV Timer allows access control of “pay” channels while allowing transparent access to free programming.
Projector
Assisted Sculpture Turntable To obtain an accurate likeness, a sculptor must utilize some form of reference material. Photographs are the most widely used reference material, but they offer a limited dimensional perspective and can cause distractions when the artist looks away from the sculpture to study the photograph. However, by joining a rotary table mechanism and a slide projector, the rotary table actuated slide projector provides a continuously correct three-dimensional perspective of a slide-projected image to the sculpture in progress.
The
Geo-Mite The Geo-Mite is
a small microprocessor-controlled vibration alarm system. It uses a
sensor that was developed to perform acoustic surveying for the oil
industry. This sensor can detect small vibrations and generate an output
voltage proportional to the vibration. The Geo-Mite converts this output
to a binary condition and then counts the number of these vibrations
occurring each second. This level of vibration is displayed on an LED
bar graph on the front of the Geo-Mite. If this level exceeds a programmable
threshold, the Geo-Mite will sound an alarm and send an X-10 On command
to a selected device. The unit also can operate without the X-10 interface
and function as a simple audible vibration alarm.
