摘要:
The present invention relates to a method of fabricating optical devices and in particular to a method of fabricating integrated opto-electronic devices, and to an opto-electronic device. A plasma enhanced chemical vapor deposition process (PECVD) is used to deposit an optical device integrated in silicon onto an electronic device fabricated in silicon. Relatively low temperatures are utilized and, in order to reduce losses of a waveguide in the optical device in the wavelength range 1.50 to 1.53 .mu.m, the deposition process is carried out in the absence of nitrogen. An optical device is disclosed which comprises an integrated construction incorporating an optical waveguide in silica and a photonic transducer in silicon.
摘要:
There is disclosed a method of constructing photosensitive waveguides on silicon wafers through the utilization of a Plasma Enhanced Vapor Deposition (PECVD) system. The deposition is utilized to vary the refractive index of resulting structures when they have been subject to Ultra Violet (UV) post processing.
摘要:
A system for a clinical lab that is capable of automatically processing, including sorting, of multiple specimen containers. The system comprises a central controller, a workstation, one or more analyzers, and an automated centrifuge. The workstation has automatic detectors for detecting the presence of a holder holding specimen containers. The workstation has a bar code reader for reading bar codes on the containers. The system has a transport subsystem, preferably a workstation robotic arm and an analyzer robotic arm for transporting the specimen containers, moving them to and from the workstation, to and from the analyzers, and to and from the centrifuge. The centrifuge is loaded with buckets containing specimen containers. The workstation can be provided with a balance system for balancing the weight of the buckets used. The workstation can also have a decapper for automatically removing caps from the specimen containers.

An edge-sealed barrier film composite. The composite includes a substrate and at least one initial barrier stack adjacent to the substrate. The at least one initial barrier stack includes at least one decoupling layer and at least one barrier layer. One of the barrier layers has an area greater than the area of one of the decoupling layers. The decoupling layer is sealed by the first barrier layer within the area of barrier material. An edge-sealed, encapsulated environmentally sensitive device is provided. A method of making the edge-sealed barrier film composite is also provided.

A retractable stethoscope comprising a case, at least one piece of acoustic tubing, at least one ear piece, and a chest piece. The chest piece is coupled to one end of the acoustic tubing, and at least one ear piece is coupled to another end of the acoustic tubing. The length of the acoustic tubing may extend from and retract into the case from the ear piece end, the chest piece end of the acoustic tubing, or both ends either independently or simultaneously. The retractable stethoscope may further comprise a belt clip.
