US Classification:

372 25, 372 6, 372 21, 372 99

Abstract:

Femtosecond pulse trains in waveguide lasers with high fundamental repetition rates are achieved by exploiting the nonlinearity in the waveguide. Components of the apparatus include an optical resonator, a saturable absorber for starting and stabilizing mode-locking, and a gain element. Part of the laser cavity or the entire laser cavity is made of waveguide or fiber (collectively called “waveguide” herein). The net dispersion of the laser cavity can be anomalous. This anomalous dispersion in combination with the positive self-phase modulation nonlinearity in the waveguide creates soliton formation to shorten the pulse duration in the invented lasers. Conversely, a normal dispersive waveguide with negative self-phase modulation nonlinearity can also be used.

International Classification:

G06F 19/10

US Classification:

700135

Abstract:

Techniques which employ structure-from-motion modeling techniques to produce 3-D models of any desired accuracy of any surface I the techniques, a pattern is applied to the surface to be modeled The pattern includes elements which are unique within the pattern as applied to the surface and which have a density in the pattern such that when two-dimensional images are made of the surface, correlatable features having the density required for the desired accuracy may be extracted from the two dimensional images In one example of the techniques, a consumer may make the images required to produce a model of his or her body by donning a garment with a pattern having the necessary uniqueness and density, and then using any digital camera to take pictures of their body wearing the garment The model may then be produced from the pictures.

International Classification:

H03H 9/215
H03H 9/02
H01L 41/04

Abstract:

The disclosed technology generally relates to quartz crystal devices and more particularly to quartz crystal devices configured to vibrate in torsional mode. In one aspect, a quartz crystal device configured for temperature sensing comprises a fork-shaped quartz crystal comprising a pair of elongate tines laterally extending from a base region in a horizontal lengthwise direction of the fork-shaped quartz crystal. Each of the tines has formed on one or both of opposing sides thereof a vertically protruding line structure laterally elongated in the horizontal lengthwise direction. The quartz crystal device further comprises a first electrode and a second electrode formed on the one or both of the opposing sides of each of the tines and configured such that, when an electrical bias is applied between the first and second electrodes, the fork-shaped quartz crystal vibrates in a torsional mode in which each of the tines twists about a respective axis extending in the horizontal lengthwise direction.
