The invention relates to measuring devices used in measuring angular velocity and, more precisely, to vibrating micro-mechanical sensors of angular velocity. The sensor of angular velocity according to the invention is adapted to measure angular velocity in relation to two or three axes, and at the least two seismic masses (34-36, 52-53, 71-75) of the sensor of angular velocity are adapted to be a...

Rubber particles in a water and polyhydric alcohol solution are added to an asphalt whereby the polyhydric alcohol substantially coats the rubber particles resulting in an easily mixed composition with the mixing temperature being reduced to a rang e of from about 250.degree.F to about 310.degree.F resulting in considerable ener gy savings. In a similar manner, a filler can be substantially coated...

A lighting system comprises a light fixture (100) and a corresponding remote control transmitter (200). The light fixture can comprise at least one electrically energizable light source (102), at least one local condition sensor (103), a receiver (105), a memory (104), and a controller (101). The controller automatically controls energization of the light source as a function of input from the loc...

Methods and systems for roof estimation are described. Example embodiments include a roof estimation system, which generates and provides roof estimate reports annotated with indications of the size, geometry, pitch and/or orientation o f the roof sections of a building.

Poly(trimethylene)terephthalate filaments are used alone or in combination with other types of filaments to make medical or surgical devices and to achieve wound closure or tissue approximation.

Normally hydroelectric dam powerhouses use river flow once before discharging it as turbulent tailwater, ineffective to spin turbines. The present invention uses tapered channels to confine and constrict turbulent tailwater into laminar flow that drives turbines both submersible and floatable utilizing the same water three times concurrently to generate new electricity. Channels originate adjacent...
