Measuring very small angles with high precision from a distance on the order of meters or more, as is needed in applications such as calibrating coordinate measuring machines (CMMs), or aligning gravitational wave detector or particle accelerator components, currently requires the use of laser interferometry,
This invention relates to (a) ducted turbine(s) coupled with (a) generator(s), driven by the airstream of a moving vehicle. This unit(s) can be installed into existing aerodynamic rooftop-fairings of trucks, and / or be part of specially designed aerodynamic rooftop, or in the case of trains, in front of or on top of railroad cars.
I/ Meissner Effect
1/ Diamagnetism will occur if the orbital velocity of electrons vary.
2/ At low temperatures( near absolute zero ), the electrons of the phonon’s atoms move slowly & thus cause the diamagnetic effect.
3/ Therefore there is no magnetic field inside a superconductor.
Modern fabrication techniques permit manufacture of economical personnel and package security scanners integrating traditional metal detection with high-resolution ultrasound imaging of dense materials, such as explosives, concealed in clothing or small packages.
This scanner can be manufactured using present semiconductor fabrication methods,
The reciprocating engine has been a paradigm for industry and a touchstone for engine technology for over one hundred years. Engines used today though, are only five to seven percent mechanically efficient at best. They expel more than 75% of the thermal energy of its fuel out the radiator and exhaust! Wasted!
I suggest that we combine infrastructure elements; ie: topping the sound barrier walls that buffer neighborhoods from traffic sounds with solar panels. These walls are supported by metal I-beams footed in concrete.
East-west highways (Interstate 70-80-90) have at least one wall facing south across lanes of traffic.
Cancer is the second biggest killer in the world after cardiovascular disease, and is projected to overtake it in the near future. Just in the US, every year there are 140k new cases and 49k deaths of colorectal cancer, and 221k new cases and 157k deaths of lung cancer.
Cancer mutations are very important in the treatment of cancer,
This invention will present 3D displays without the need for special glasses. It will permit an observer to move about and see different views.
This device makes extensive use of holographic optical elements. HOEs are holograms that function as optical elements such as lenses and mirrors for narrow band light such as that produced by a laser.
According to a recent survey conducted by the UN, the population of elderly people will increase to a large extent by the year 2020. People 65+ represented 12.4% of the population in the year 2000 but are expected to grow by 19% by 2030. Also, the population of elderly staying alone at home is increasing day by day.
The Hospital Air Cleaner is a direct contact dessicant air conditioner, intended to remove airborn bacteria and dust particles (skin and hair flakes) carrying surface bacteria. This device is intended for full high volume airflow use throughout hospitals to reduce incidence of hospital aquired infections, by the removal of pathogens in locations where hepa filtration is not used.
