This invention relates to 2° order biquad/universal continuous time IF analog active filters for telecommunications and active full self-compensation techniques to improve the frequency range, the stability and/or the selectivity of the filters with a very low, or as if zero, cost. These techniques are the only ones in the world that(fully) erase the parasitic poles using a single resistor or an additional operational amplifier with a functionally filtering output; this means that in several applications the additional manufacturing cost is zero and, however, very low.
This is the key principle which makes very evaluable this patent (37 claims, of which 9 independent, and 38 drawings).

An alternator is described which has no moving parts and replaces the alternator and belt in current vehicle engines.

The alternator works by using waste heat from the car's internal combustion engine to create electricity, instead of a moving magnetic field.

The largest savings on engine drag will be significant at all speeds due to eliminating the belt drive.

The second largest savings will be weight - not only the alternator, but also the starter motor, which has to overcome the alternator to run the engine.

Note, due to using waste heat, the alternator can continue to run after the car is turned off, allowing electric fans to do the same without draining the batteries.

Finally there is an alternative to the common tweezers. H-Square Corporation introduces the new, easy to use Nu-twEZers™.

Used throughout the semiconductor, biotech and many other industries, tweezers have not changed much in 500 years when they were first commercialized. Artifacts of crude tweezers are dated from around 300BC. So it is about time for a new design.

H-Square’s ergonomics minded engineers spring loaded these tools to assure consistent force and eliminate strain on the operator's hands while holding the object. The Nu-twEZers lessens the chance of Carpal Tunnel Syndrome, which can be caused from continued tweezers use. Next, ESD safety protects electronic items and semiconductor chips from damage while keeping particles from sticking to tool for cleanliness.

Everybody is a witness to what is going on in the gulf of Mexico, millions of gallons of fuel are leaking from a broken pipe from a BP offshore drilling platform. It is only getting bigger and is now worse than anyone thought. The oil spill has now surpassed BP's "worst case scenario," meaning it could become a major ecological disaster and could even begin to rival the damage of the Exxon Valdez Oil Spill in Prince William Sound, Alaska, in 1989. BP failed to contain this disaster because they were not prepared to deal with such a disaster. The truth is, no one is prepared to face that kind of problem. We saw BP engineers designing and testing ...

A super-sized cream separator is to be used to gather the oil slick using a properly equipped ship to take the separated oil into its hold and return to the sea. Such a separator needs to be sized to collect thousands of gallons of water/oil-slick and centrifuge it.

Several sizes of such ships can be used, one for open sea collection, one for shallow water use, and even one for inland waterways and marches. The elimination of the use of toxic dispersants with its associated problems.

There are several companies that have the capability and expertise to produce such ...

The idea to utilize waves in elastic solids for generating rotational motion goes back to Sashida (1982) and has become widespread in mechatronic systems, for instance in photo cameras for focusing the lenses.
The basic idea behind the so called travelling-wave-type-motor are the elliptic trajectories of the surface points in the stator. The wave crests in contact with the rotor are producing a directed friction force making the rotor move. Thus the energy is converted twice. First electrical energy is converted into mechanical in terms of high-frequency vibration, which is subsequently converted again by a frictional contact in kinetic energy of a planar motion.
The advantages of this kind of motors are manifold. They offer high positioning resolution, compact ...

Abstract

Porcupine Quill ceramic heat exchanger promotes both - free air circulation and maximization of caloric transfer capabilities. The ceramic has half the weight of copper and three-quarters the weight of aluminum and is resistant to most corrosive or abrasive effluents with caloric conductance of .375, relative to that of copper. For various liquids this type of exchanger offers greater heat conductance per inch of construction than other types of exchangers. The quills originate at the center of the tube, and travel through the wall of the tube to the air. As the construction is molded in place, there are no seams to weaken the structural integrity of the tube. The tubes may be molded in linear, sinusoidal or ...

A radioisotope direct-charging battery, also known as an atomic battery, can normally be compared to a parallel-plate capacitor with a self-charging plate. Electrically-charged particles, such as alpha or beta particles, are emitted from a radioactive source and pass through an insulating or dielectric medium before being deposited onto a collector-plate where the output voltage of the battery as measured between the emitting-plate and the collector-plate can be of a magnitude of tens or hundreds of thousands of volts dc. Radioisotope direct-charging batteries have been around for over a hundred years, yet there is still no effective means for utilizing their high voltage dc output to do anything useful. Electronic components, especially switches, are simply not available for converting the ...

Resonant cyclic energy flow systems (RCEFS) are designed for resonant generation of mechanical or electromagnetic vibratory or oscillatory energy through excitation of not standing but the traveling, namely – revolving, natural waves within a distributed parameter system. The necessary and sufficient condition for realization of natural revolving waves in a system domain is the availability of multiple natural frequencies for this domain shape. Circular annular resonator has the most suitable shape for this technical purpose. An example of acoustical RCEFS is shown in fig.1. The cyclic excitation of such resonator with the natural angular frequency leads to the forced resonant revolving vibration due to accumulation of oscillatory energy. At steady revolving regime the wave power is restricted only with ...

Description

Thanks to a great marketing campaign, most TV watchers are now familiar with the fact that CSX trains can move a ton of freight 432 miles on a single gallon of fuel. But what if we could increase the efficiency of the train technology? The lowly train truck that supports the weight of the car it sits under uses journal bearings and grease to provide the sliding surfaces necessary for both the wheelsets to rotate. At least some portion of the energy needed to move a train is lost to the friction in each bearing. With trains of coal numbering over 160 hopper cars, 1920 sets of bearings contributing to the load the engine must overcome. The cost ...
