| 20110034797 | NON-INVASIVE MEASURING OF LOAD-INDUCED ELECTRIC POTENTIALS IN DIARTHROIDIAL JOINTS - There is described a method for non-invasively measuring electrical activity in a joint of a subject, the method comprising: removably attaching in a non-invasive manner at least two electrodes to a skin surface around an articulation comprising the joint; generating electroarthrographic potentials within the joint by loading the articulation; capturing the electroarthrographic potentials using the at least two electrodes; discriminating between electroarthrographic potentials originating from joint tissue activity and those from other sources; and generating measurement signals representing the electrical activity of joint tissue. | 02-10-2011 |
| 20100061689 | Process for Fabricating Buried Optical Waveguides Using Laser Ablation - The present invention is concerned with a process for fabricating a buried optical waveguide, comprising providing a multi-layer piece of material having a waveguide core layer, generating a laser beam and producing by ablation at least two trenches by applying the laser beam onto the multi-layer piece of material. The two trenches extend through the multi-layer piece of material including the core layer. Upon the ablation, melted material from the multi-layer piece is produced and the core layer is encapsulated between the two trenches with the melted material to produce the buried optical waveguide in the multi-layer piece of material. The present invention also relates to a buried optical waveguide comprising a multi-layer piece of material having a waveguide core layer, at least two trenches laser ablated through the multi-layer piece of material including the core layer and encapsulating material having melted from the multi-layer piece upon laser ablation and leaked to cover and therefore encapsulate the core layer in the at least two trenches to thereby form the buried optical waveguide. | 03-11-2010 |
| 20090231682 | HIGH-POWER FIBER AMPLIFIER - Fiber light amplifiers adapted for high power application are provided. In embodiments of the invention, the light signal to be amplified is coupled to a cladding mode of an active waveguide region which is cladding doped. The amplified light is coupled to an output fiber have waveguiding properties matching those of the active cladding of the active waveguide region. In other embodiments, two or more amplifying stages are provided coupled by a wavelength selective loss element which couples the Stokes wave co-propagating with the signal to be amplified out of the signal guiding mode prior to the onset of SRS. | 09-17-2009 |
| 20090097809 | Ferroelectric all-polymer hollow bragg fibers for terahertz guidance - A method for fabricating a terahertz waveguide comprises forming a multilayer reflector formed of alternating layers of first and second polymer materials with distinct refractive indices, and defining with the multilayer reflector a hollow core through which terahertz radiation propagates. The corresponding terahertz waveguide comprises the multilayer reflector formed of the alternating layers of the first and second polymer materials with distinct refractive indices, and a hollow core defined by the multilayer reflector and through which terahertz radiation propagates. | 04-16-2009 |
| 20080249194 | STABLE EMULSION AND PROCESS OF PREPARATION THEREOF - This document relates to a stable emulsion comprising a continuous phase and a dispersed phase comprising droplets. The droplets are at least partially covered with a powder and the powder comprises particles having an average size which is at least 10 times smaller than the average size of the droplets. A process for preparing the emulsion is also presented. | 10-09-2008 |
