摘要:
Improvements a portable elevated lighting system that uses LED lighting elements for illumination. The LED lights are selected based upon the light transmission angle so the fewest number of lighting elements are needed to provide an even flood or focus of light from the system. A reflector works as a heat sink to remove heat from the LED lights and extend the operation life of the LED's. Thermal paste and or a thermal pad is used between the LED lighting element and the frame to conduct sufficient heat away from the LED element. Two versions are shown as a stadium light and as a circular flood light that provides lighting without shadows or bright areas. The system can be operated from a generator or solar for charging batteries so the lighting can operate self-contained without producing noise.
摘要:
An impact resistant device is provided comprising a flexible support matrix and a plurality of energy absorbing elements operatively connected to the support matrix, each element comprising at least one ceramic material and at least one strain rate sensitive material. The impact resistant device can be worn as body armor to protect the wearer from high velocity projectiles.
摘要:
A bone substitute for use in impact testing of a structure simulating the human body which includes a member fabricated from epoxy resin and having a lengthwise dimension, and a fiberglass sheath embedded in an outer circumferential portion of the member, the sheath having glass fibers oriented along the length of the member.
摘要:
A slide bearing surface element is disclosed which can be used in prosthetic joints or mechanical bearing devices. The element has a composite coating made of a matrix of epoxy resin with particles of Al.sub.2 O.sub.3 dispersed therein. Cu or stainless steel particles are included to increase thermal conductivity.
摘要:
A flexographic printing system for printing flat corrugated sheets using radiation curable inks. An ultraviolet curing unit is positioned after each of the printing stations. The ink applied at each station is partially cured before a different color ink is applied at the next printing station.
