  • Patent number: 9645085
    Abstract: This invention generally relates to optical devices that can collect and detect signal emissions effectively while allowing the excitation light path and the sample flow path to coexist non-obstructively in a compact format. More specifically, this invention relates to a compact device having a multilayer coating on the structure surface and a wave guiding structure. In the device, using the surface plasmon coupling effect, the majority of the optical emission from the emitter on top of the multilayer coating is distributed toward the wave guiding structure. The wave guiding structure then further directs on signal to the detector with a high efficiency.

  • Patent number: 9452237
    Abstract: A smart antimicrobial material and dressing to inhibit microbial growth is provided. Endogenous chemicals, such as metabolites produced from bacteria are utilized as chemical substrates and converted by enzymes to produce a disinfecting compound that will in turn inhibit the targeted microorganism. The material shall remain passive until such time as it encounters a microbe which expresses and/or secretes specific metabolites or markers. The enzyme or enzymes embedded in the smart material converts the metabolite into a disinfecting compound, which in turn either kills the microorganism or prevents it from multiplying on the surface of the material.

  • Patent number: 9012853
    Abstract: A highly scalable platform for radiation measurement data collection with high precision time stamping and time measurements between the elements in the detection array uses IEEE 1588 with or without Synchronous Ethernet (timing over Ethernet) to synchronize the measurements. At a minimum, the system includes at least two radiation detector units, an IEEE 1588 and SyncE enabled Ethernet switch, and a computer for processing. The addition of timing over Ethernet and power over Ethernet (PoE) allows a radiation measurement system to operate with a single Ethernet cable, simplifying deployment of detectors using standardized technology with a multitude of configuration possibilities. This eliminates the need for an additional hardware for the timing measurements which simplifies the detection system, reduces the cost of the deployment, reduces the power consumption of the detection system and reduces the overall size of the system.
