In an optical waveguide fabrication process, medium weight, relatively stable ions, such as oxygen ions, are implanted, preferably in a multiple-step, multiple-energy level process, into GaAs, InP or other like III-V materials and heterostructures and then annealed by radiant heat, in order to produ.....

Ultra-precision freeform surfaces are important to the development of complex and micro-optical-electro-mechanical devices used in many photonics and telecommunication products such as F-theta lenses for laser printers. These surfaces are complex and large scale surface topologies with shapes that g.....

A portable ultrasound palpation device for measuring the Young's modulus and the thickness of a soft tissue layer includes a hand-holdable palpation probe having an ultrasonic transceiver connected in series with a load cell. During a test, the probe is placed on the tissue surface with a bony subst.....
