The disease detection circuitry is configured to apply the model to the data events to detect an occurrence of the disease. The model is generated using machine learning technique based on time-series data events from patients that are diagnosed with/without the disease. The memory circuit is configured to store configurations of a model for detecting a disease. The interface circuit is configured to receive data events associated with a patient sampled at different time for disease detection. The system includes an interface circuit, a memory circuit, and a disease detection circuitry. METHOD AND APPARATUS FOR DISEASE DETECTION - Aspects of the disclosure provide a system for disease detection. Some embodiments amplify an optical signal in a gain fiber having an output end, output the forward-propagating amplified signal as a high-brightness optical beam (having a first Rayleigh range) into a removable delivery fiber having a non-circular waveguide, output the amplified signal from a distal end of the delivery fiber, and, without the use of a non-linear optical isolator, inhibit backward-propagating light from re-entering the gain fiber. Some embodiments use a delivery fiber having a non-circular core in order to spread a single-mode signal into multiple modes such that any backward-propagating reflection is inhibited from reentering the single-mode amplifier. Eliminating the isolator improves efficiency and reduces cost. SYSTEM AND METHOD FOR A DELIVERY FIBER FOR ISOLATION AGAINST BACK REFLECTIONS - An apparatus and method that provide optical isolation by permitting substantially all forward-propagating light into a delivery fiber from an optical amplifier and substantially preventing backward-traveling light from the delivery fiber entering the optical amplifier without the use of a conventional optical isolator. The resulting set of conforming layers can be sealed. The process may be repeated to form multiple layers of conforming circuits with electrical connections between layers formed by blind microvias. The first set of conforming layers is created by applying an oxide dielectric layer to the surface, applying a conductive material layer to the oxide dielectric layer, applying a resist layer to the conductive material layer, patterning the resist layer according to a desired circuit layout, etching the surface to remove exposed conductive material, and stripping the resist layer. As a result, the light will be either reflected or absorbed.Lockheed Martin Corporation Lockheed Martin Corporation Patent applicationsįINE LINE 3D NON-PLANAR CONFORMING CIRCUIT - A method of producing a non-planar conforming circuit on a non-planar surface includes creating a first set of conforming layers. Then the light of 90° polarization becomes vertical to the input polarizer and can not leave the isolator. Next, as it passes through the Faraday rotator, it continues to be rotated for anther 45° in the same direction. ![]() However in the backward mode, the light first enters into the output polarizer with a 45° polarization. Thus, the light finally leaves the output polarizer at 45° polarization. When laser light reaches the Faraday rotator, the Faraday rotator rod will rotate by 45° polarization. ![]() The forward mode enables light enter into the input polarizer and become linearly polarized. One is the forward mode and the other is the backward mode. The rotation direction depends on the direction of the magnetic field instead of the direction of light transmission.Īccording to different light directions, there are two types of operation modes. Faraday effect refers to a phenomenon that the plane of polarized light rotates while transmitting through glass (or other materials) that is exposed to a magnetic field. The operation of optical isolator is based on the Faraday effect which was discovered by Michael Faraday in 1842.
