Abstract:
An illuminated walking assistance apparatus is disclosed. In at least one embodiment, the apparatus provides an elongated staff having a ground-engaging tip portion at a first end and a handle at an opposing second end. The staff provides a light pipe positioned proximal the tip portion and having a light-emitting member disposed therein to selectively illuminate the ground proximal the tip portion. The staff further provides a red nightlight which is always on so as to facilitate locating the apparatus in a dark environment.

Abstract:
A system for treating target cells with both positive and negative ions comprises a bi-polar beam delivery system configured to create and deliver both positive ion beams and negative ion beams. The bi-polar beam delivery system comprises a bi-polar accelerator configured to accelerate positive and negative ions in the same direction making such a bi-polar bema delivery system practical.
Abstract:
A cooling fan for dissipating heat requiring relatively little electrical power to operate. The fan includes a fan blade, constructed from flexible metal or plastic, anchored at one end and having a permanent magnet mounted at the other end. An external drive mechanism, such as a position sensor or an oscillator, provides a drive pulse to the coil. The fan blade is placed in motion by energizing a coil which is disposed about a core constructed of magnetically permeable material and positioned adjacent the magnet. Upon energization of the coil, the magnet mounted on the blade reacts to the magnetic field generated by the coil, causing the blade to move away from the coil. When the magnet, due to the flexibility of the fan blade, moves back towards the coil, a voltage is induced in the coil by the magnet, thus causing current to flow through the coil to apply a kick or power pulse of magnetic energy to the magnet. This process continues as the blade moves from side to side. The fan blade thus functions as a resonant mechanical oscillator and as it moves, air is caused to move over the device to be cooled.
Abstract:
A method for measuring accurately the optical thickness and index of refraction of thin, optical membranes includes directing light onto the membrane at one or more known angles of incidence, finding at least one angle of incidence, called a null angle, where the membrane reflects substantially none of the incident light, then calculating the optical thickness of the membrane, its index of refraction, or both, from one or more such null angles. Apparatus for this purpose includes means for directing a light beam onto thin, optical membranes, means for varying the angle of incidence of a light beam upon the membrane, and means for detecting the angles of incidence of the light beam on the membrane, including the null angles.
