  • Patent number: 10256600
    Abstract: The Hybrid Photonic Plasmonic Interconnect (HyPPI) combines both low loss photonic signal propagation and passive routing with ultra-compact plasmonic devices. These optical interconnects therefore uniquely combine fast operational data-bandwidths (in hundreds of Gbps) for light manipulation with low optical attenuation losses by hybridizing low loss photonics with strong light-matter-interaction plasmonics to create, modulate, switch and detect light efficiently at the same time. Initial implementations were considered for on-chip photonic integration, but also promising for free space or fiber-based systems. In general two technical options exist, which distinguished by the method the electric-optic conversion is executed: the extrinsic modulation method consists of an continuous wave source such as an LED or laser operating at steady power output, and signal encoding is done via an electro-optic modulator downstream of the source in the interconnect.

  • Patent number: 10254436
    Abstract: A scanning system, corresponding bracket and method are for scanning an object. The system has a frame defining a scanning chamber in which the object to be scanned is placed. The system also has a displacement assembly which displaces the object into and out of the scanning chamber. The system can also have a source which emits electromagnetic radiation or X-rays against the object within the scanning chamber such that the EM radiation passes through the object. The system can also have detectors arranged around the scanning chamber which detect the EM radiation which passes through the object. Each of the detectors forms a detector angle with a plane which can vary from one detector to the next. Similarly, the source can form an angle with the horizontal plane. The system, bracket, and method allow for the production of representative three-dimensional views of the object.

  • Patent number: 10247645
    Abstract: A system for tracking one or more subjects for collecting airborne contaminants. The system includes one or more subjects configured to collect air contaminants. Each of the one or more subjects includes an identification tag encoded with identification information identifying the each subject. The system further includes an identification reader configured to decode the identification information encoded within the identification tag of a scanned one of the one or more identification tags. A computer receives and stores the decoded identification information in a record in a database. The computer may also receive and stored an identification code for a user who scanned the scanned identification tag in the record in the database. Additional records in the database are created each time the identification tag of one of the one or more subjects is scanned. The one or more subjects are thereby tracked as they collect airborne contaminants and are incubated.

  • Patent number: 10175366
    Abstract: A radiation detector that improves accurately a fluorescence emission-time. A limiter circuit instead of a low-pass filter and a high-pass filter removes a noise component of the amplifier output. The limiter circuit blocks passing through the amplification signal when the amplification signal output from the amplifier a is lower than the limit level. Accordingly, a noise component output not related to the fluorescence detection from the amplifier a is blocked by the limiter circuit L and is unable to reach to the addition circuit. When the amplification signal output from the amplifier a is larger than the limit level, the limiter circuit L passes through such amplification signal; so that the signal, which is related to a fluorescence detection, that the amplifier a outputs can be absolutely input into the fluorescence emission-time calculation element.

  • Patent number: 10139283
    Abstract: Methods and systems for performing non-contact temperature measurements of optical elements with long wavelength infrared light are described herein. The optical elements under measurement exhibit low emissivity to long wavelength infrared light and are often highly reflective or highly transmissive to long wavelength infrared light. In one aspect, a material coating having high emissivity, low reflectivity, and low transmission at long wavelength IR wavelengths is disposed over selected portions of one or more optical elements of a metrology or inspection system. The locations of the material coating are outside the direct optical path of the primary measurement light employed by the metrology or inspection system to perform measurements of a specimen. Temperature measurements of the front and back surfaces of an IR-transparent optical element are performed with a single IR camera. Temperature measurements are performed through multiple optical elements in an optical path of a primary measurement beam.

  • Patent number: 10120099
    Abstract: Devices and methods for a rugged semiconductor radiation detector are provided. The semiconductor detector may include a hermetically sealed housing and a semiconductor disposed within the housing that has a first surface and a second surface opposite one another. A first metallization layer may at least partially cover the first surface of the semiconductor and a second metallization layer may at least partially cover the second surface of the semiconductor. The first metallization layer or the second metallization layer, or both, do not extend completely to an edge of the semiconductor, thereby providing a nonconductive buffer zone. This reduces electrical field stresses that occur when a voltage potential is applied between the first metallization layer and the second metallization layer and reduces a likelihood of electrical failure (e.g., due to arcing).
