A filter device is installed in the chamber for filtering the lubricating oil. An access cove...

Living, fermentable yeast cells are prepared having an enzyme or mixture of enzymes coupled thereto. Enzyme coupling is carried out by contacting at least partially dehydrated living yeast cells with an aqueous enzyme solution to cause the yeast cells to rehydrate and a layer of enzyme to form on the surface of the yeast cells, and than contacting the rehydrated yeast cells with an enzyme-precipit...

A system for remote measurement of structural forces includes a plurality of microbend transducers mounted along the length of the structure for microbending an optical fiber in response to structural forces, such as stress acting upon an oil or gas pipeline or the like. An optical time domain reflectometer (OTDR) has a light source for launching a pulsed optical signal for passage through the fib...

A guidance method and system for an automotive vehicle which switches from an electronic navigational signal method to a dead reckoning method when any of the field strengths of three navigational electromagnetic wave signals drops below a predetermined lower limit or vice versa when the field strengths of the three navigational electromagnetic wave signals all exceed the lower limit. Therefore, e...

An apparatus in which optical measurement of liquid, especially blood, may be carried out quickly and easily, at low cost and with great accuracy.
